Description

  The present invention relates to eyeglasses with a light emitting function and a spectacle system, and more particularly to eyeglasses with a light emitting function having a light emitting function, and a spectacle system including such glasses with a light emitting function.

  So far, some glasses having additional functions have been proposed. For example, Patent Document 1 describes glasses having a light emitting function as an additional function. The eyeglasses with a light emitting function described in Patent Document 1 have a light emitting member that emits light having an illuminance and a wavelength that promotes an awakening action or a light therapy effect in a frame portion of the eyeglasses. The light emitting member irradiates the wearer's eyes with light having such illuminance and wavelength. The light emitted from the light-emitting member is directly incident on the wearer's eyes, whereby the wearer's brain is stimulated and the secretion of melatonin causing drowsiness is suppressed. By suppressing the secretion of melatonin, the sleepiness of the wearer is awakened or the wearer feels refreshed.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 shows the appearance of eyeglasses with a light emitting function according to the first embodiment of the present invention. In this specification, “front”, “rear”, “left”, “right”, “upper”, and “lower” refer to the state in which the glasses 10 with the light emitting function are worn on the wearer's head. "Front", "Rear", "Left", "Right", "Up", and "Down" as viewed from the wearer. It is assumed that the vertical direction of the front part of the eyeglasses 10 is referred to, and the “front part” is a generic name of the front part of the eyeglasses including the right and left rims, the Grings bridge, and the wisdom.

  The glasses with a light emitting function (hereinafter also simply referred to as glasses) 10 include a frame 101, a bridge 102, a hinge 103, a temple 104, a lens 105, and a nose pad 106, similarly to normal glasses. The glasses 10 further include a light source module 110 and a power supply module 111. At least one of the light source module 110 and the power supply module 111 is detachable from the temple 104 and is configured to be replaceable. The light source module 110 includes a light source. The power supply module 111 includes a power source such as a battery. The positions where the light source module 110 and the power supply module 111 are arranged are arbitrary, and are not limited to the positions illustrated in FIG.

  The glasses 10 of the present embodiment have a beauty function that makes the wearer's eyes look bright as an additional function. The glasses 10 have a light guide member 52 on the wearer side of the frame 101. Light emitted from the light source in the light source module 110 is incident on the light guide member 52. The light guide member 52 emits illumination light toward the wearer's face while guiding light incident from the light source. The light guide member 52 preferably does not irradiate illumination light in front of the glasses 10.

  FIG. 2 is a functional block diagram of the glasses 10. The glasses 10 include a power source 11, a control unit 12, a surrounding environment detection unit 13, a user state detection unit 14, an open / close sensor 15, a contact state sensor 16, a motion sensor 17, and a light emitting unit 50. The light emitting unit 50 includes a light source. The light source of the light emitting unit 50, the control unit 12, the surrounding environment detection unit 13, and the user state detection unit 14 are included in the light source module 110 of FIG. The power supply 11 is included in the power supply module 111 of FIG. The module may be divided by the light source, the control means 12, the surrounding environment detection means 13, and the user state detection means 14.

  The power supply 11 supplies power to each part in the glasses 10. For the power supply 11, for example, a small storage battery is used. The storage battery may be disposable or rechargeable. The power supply 11 is mounted, for example, on the ear pad portion of the temple 104 (see FIG. 1). Instead of mounting the power source on the glasses 10, power may be supplied from the outside of the glasses 10. For example, power may be supplied from an external power source to the glasses 10 through a power line, or power may be supplied from the external power source to the glasses 10 using a wireless power feeding method.

  The light emitting unit 50 irradiates the illumination light toward the outside of the region where the wearer's eye opening portion is assumed to exist when the wearer wears the glasses 10. The light emitting unit 50 is disposed on the frame 101 in a state where, for example, light emitted in the direction with the highest intensity in the intensity distribution of light emitted therefrom does not go to the opening of the wearer's eyes. Alternatively, the light emitting unit 50 has an illuminance of illumination light in an area where it is assumed that there is a part of the wearer's face that is the shortest distance from the light emitting unit 50 when the wearer is wearing. It arrange | positions at the flame | frame 101 in the state which becomes higher than the illumination intensity of the illumination light in the area | region assumed that opening exists.

  Here, the “eye opening” region refers to a region sandwiched between the upper and lower eyelids connecting the top of the eye and the corner of the eye. FIG. 3 shows the eye portion of the wearer. In the figure, an eye head 205 represents a point (outer eye corner point) where the edge of the upper eyelid 207 and the edge of the lower eyelid 208 are in contact with each other on the outer side of the eye 201 when the eye 201 is opened. An eye corner 206 represents a point (inner eye corner point) where the edge of the upper eyelid 207 and the edge of the lower eyelid 208 are in contact with each other on the inner side of the eye 201 when the eye 201 is opened. In the present embodiment, when the wearer opens the eye 201 in a normal state, a tear (eye cleft) between the upper eyelid 207 and the lower eyelid 208 occurs between the eyes 205 and the outer corners 206. This part is defined as an eye opening.

  FIG. 4 shows the light emitting unit 50. The light emitting unit 50 includes a light source 51 and a light guide member 52. For example, as shown in FIG. 1, the light guide member 52 is disposed in a portion around the lens 105 of the frame 101. The light source 51 is a light source of illumination light emitted from the light guide member 52. For the light source 51, for example, a light emitting element such as an LED (Light Emitted Diode) can be used. The light source 51 may emit light of a plurality of colors, or may emit monochromatic light. The light source 51 is preferably configured so that at least one of the color and intensity of the emitted light can be controlled. In the glasses 10, the light source 51 is disposed at each of both ends of the front connected to the temple 104, for example. The light emitted from the light source 51 travels through the light guide member 52 and is irradiated to the wearer as illumination light.

  FIG. 5 shows the positional relationship between the light guide member 52 and the wearer's eyes. The light guide member 52 is disposed on the wearer side of the frame 101, for example, and irradiates illumination light from the periphery of the lens 105 toward the wearer. In general, the optical axis of the lens 105 faces the wearer's eye 201, and the light guide member 52 is disposed at a position away from the eye 201. The portion of the face of the wearer that has the shortest distance from the light emitting unit 50 (particularly the light guide member 52) in a state where the wearer is wearing is away from the opening of the eye 201. It should be noted that the portion of the wearer's face that is the shortest distance from the light guide member 52 when the wearer is wearing may change depending on the unevenness of the wearer's face. Hereinafter, for the sake of convenience, the distance between the light emitting unit 50 and the portion of the position where the straight line extending in the horizontal direction from the light guide member 52 and the surface of the wearer's face intersect with the spectacles 10 being worn is the shortest. It will be described as a part of the wearer's face.

  In FIG. 5, consider a straight line L that is parallel to a straight line passing through the two light guide members 52 above and below the frame 101 and that passes through a position where the opening of the eye 201 is assumed to exist. This straight line L is assumed to be parallel to a straight line extending in the vertical direction when the glasses 10 are worn. A point where the straight line L intersects a perpendicular line extending from the light guide member 52 on the upper side of the frame 101 to the straight line L is defined as a point A. This point A is a point that represents the face portion having the shortest distance from the light guide member in the state where the wearer wears the glasses 10. Considering the illuminance on the straight line L of the light irradiated from the light guide member 52 on the upper side of the frame 101, the illuminance is considered to be maximum at the point A.

  FIG. 6 shows the illuminance on the straight line L. FIG. In the figure, the horizontal axis represents the position on the straight line L, and the vertical axis represents the illuminance (corresponding to the intensity of the irradiated light). The position 0 represents the position of the point A, the plus coordinate position represents the position above the point A, and the minus position represents the position below the point A. Assuming that the light distribution characteristic of the light guide member 52 is not directional, the illuminance on the straight line L is maximum at the position of the point A where the distance to the light guide member 52 is the shortest, and the illuminance at the surrounding positions Decreases. The position where the opening of the eye 201 is assumed is located away from the point A, and the illuminance at that position is lower than the illuminance at the point A. Most of the illumination light emitted by the light guide member 52 is applied to the outside of the opening of the eye 201 of the wearer wearing the spectacles 10, and the light directly applied to the eye 201 is small.

  FIG. 7 is a view of the glasses 10 as viewed from the front. A light guide member 52 (see FIG. 1 and the like) is disposed on the rear side of the frame 101, and the face around the wearer, particularly the portion around the eye behind the frame 101, is emitted from the light guide member 52. Light is irradiated. When this illumination light illuminates the periphery of the eye 201 brightly, when the wearer of the spectacles 10 is observed from the outside, the visual impression tail can be improved, and / or fine lines around the eye 201, etc. Can be made inconspicuous. On the other hand, since the eye 201 is not irradiated with much illumination light, the wearer does not feel the illumination light dazzling.

  FIG. 8 shows the positional relationship between the light source 51 and the light guide member 52. The light source 51 is disposed, for example, at the position of the front portion connected to the temple 104 (see FIG. 1). The light guide member 52 is disposed, for example, behind the frame 101 that surrounds the portion where the lens 105 is mounted, over substantially the entire circumference thereof.

  Here, the light guide member 52 surrounding almost the entire circumference of the frame 101 is considered as being divided into four sections, section A to section D, as shown in FIG. The section A corresponds to a portion arranged along a portion extending in the vertical direction of the frame 101 at the front end. The section B corresponds to a portion arranged along a portion extending in the left-right direction on the lower side of the frame 101. The section C corresponds to a portion arranged along a portion extending in the vertical direction of the frame 101 near the center of the front. The section D corresponds to a portion arranged along a portion extending along the left-right direction on the upper side of the frame 101.

  The light source 51 makes light incident on the light guide member 52 downward from the front end portion connected to the temple 104. The section A is the most upstream section of the light traveling in the light guide member 52. The light traveling through the light guide member 52 decreases as it travels through the light guide member 52. For this reason, the illumination light irradiated to the wearer's face from the light guide member 52 decreases as the distance from the position of the light source 51 increases. The intensity of illumination light applied to the wearer's face in the sections A and B is stronger than the intensity of illumination light applied to the wearer's face in the sections C and D. Further, the intensity of the illumination light applied to the wearer's face in the section A is stronger than the intensity of the illumination light applied to the wearer's face in the section B.

  In general, fine wrinkles and the like are often present at the center of the eye. As described above, when light is incident on the light guide member 52 from the front end portion connected to the temple 104 from the light source 51 toward the lower side in the vertical direction, the wearer's eyes are illuminated most brightly. be able to. Therefore, the effect of making fine lines and the like inconspicuous can be expected more. Also in the section B, it is possible to make the bear under the eyes inconspicuous by irradiating the wearer's face with sufficient intensity with illumination light.

  On the other hand, in the central part of the glasses 10, a shadow may be generated due to the wearer's nose or the like, and when the illumination light emitted from the light guide member 52 is irradiated on the part, the observer feels uncomfortable. Cheap. In the above configuration, the intensity of the illumination light applied to the wearer's face in the section C is weaker than the intensity of the illumination light applied to the wearer's face in the section A, and it is difficult for the observer to feel uncomfortable.

  In addition, the light guide member 52 should just be arrange | positioned along at least one part of the flame | frame 101, and does not need to be arrange | positioned over the perimeter of the flame | frame 101. FIG. It is preferable that the illumination light emitted from the light guide member 52 is applied to at least a portion of the eye that is thought to have many fine lines. From this viewpoint, it is preferable that the light guide member 52 is disposed along at least the portion of the frame 101 that extends downward from the both ends of the front connected to the temple 104 in the vertical direction.

  Returning to FIG. 2, the control means 12 controls at least one of the color of illumination light and the intensity of light emitted from the light emitting unit 50. The control means 12 is composed of control components including, for example, a CPU (Central Processing Unit) and a memory, and a control program that operates on an OS (Operating System) and firmware. The configuration of the control means 12 is not particularly limited, and other configurations may be used. The control means 12 irradiates illumination light from the light emitting unit 50 when the beauty function is on. When the beauty function is off, the control unit 12 stops the illumination light emitted from the light emitting unit 50.

  The open / close sensor 15 detects the open / close state of the temple 104. For example, a limit switch that is turned on when the temple 104 is closed and turned off when the temple 104 is opened can be used as the open / close sensor 15. The close contact state sensor 16 detects close contact with the skin. The contact state sensor 16 is provided, for example, on at least one of the ear hook portion of the temple 104 and the nose pad 106. As the contact state sensor 16, for example, a pressure sensor that outputs a signal corresponding to the pressure can be used.

  Based on at least one of the detection signal of the open / close sensor 15 and the detection signal of the contact state sensor 16, the control unit 12 determines whether the cosmetic function is on or off. In other words, the control unit 12 emits illumination light from the light emitting unit 50 based on at least one of the detection signal of the open / close sensor 15 and the detection signal of the contact state sensor 16 or from the light emitting unit 50. Decide whether to illuminate with illumination light. For example, when the opening / closing sensor 15 outputs a signal indicating that the temple 104 is in the closed state, the control means 12 turns off the cosmetic function because the glasses 10 are not used. Further, for example, when the contact state sensor 16 outputs a signal indicating that there is no contact with the skin, the control unit 12 turns off the beauty function because the glasses 10 are not used.

  The motion sensor 17 detects the movement of the eyeball of the wearer. The motion sensor 17 includes, for example, a light emitting element such as an LED and a light receiving element such as a PD (Photo Detector). The motion sensor 17 detects the movement of the eyeball (mainly the black eye) based on, for example, a change in the amount of light received by the light receiving element accompanying the movement of the black eye. The motion sensor 17 may detect a wearer's line-of-sight direction. The control means 12 may determine whether the cosmetic function is on or off based on the movement of the eyeball detected by the motion sensor 17 in addition to or instead of the above.

  For example, when the motion sensor 17 detects that the eyeball faces in the direction associated with the stop of the illumination light and the state in which the eyeball faces in the direction continues for a predetermined time or longer, the control function 12 Turn off. Regarding the “predetermined time” for determining whether the beauty function is off, this time may always be a fixed time, or the time may be different from one scene to another.

  Instead of or in addition to the above, the beauty function may be turned off when the wearer has closed his eyes for a predetermined time or more. Whether or not the wearer closes his eyes can be determined according to whether or not the motion sensor 17 can detect the black eye. In this case, the “predetermined time” for determining whether or not the beauty function is off, as described above, this time may always be a fixed time, or it may be a time between one scene and another scene. May be different.

  The surrounding environment detection means 13 detects the surrounding environment of the glasses 10. The surrounding environment detection means 13 detects, for example, at least one of the color of the surrounding environment light, the intensity (brightness) of the surrounding environment light, the temperature of the surrounding environment, the humidity of the surrounding environment, the location, and the time zone. The surrounding environment detected by the surrounding environment detection means 13 is arbitrary and is not limited to the above. The control unit 12 controls at least one of the color of illumination light and the intensity of illumination light emitted by the light emitting unit 50 based on information on the surrounding environment detected by the surrounding environment detection unit 13. The surrounding environment detection means 13 notifies the control means 12 of the detected state of the surrounding environment as numerical data and / or data such as a predefined level value.

  The ambient environment detection unit 13 includes, for example, an ambient light color sensor 31, a light intensity sensor 32, a temperature sensor 33, and a humidity sensor 34. The ambient light color sensor 31 detects the color of the surrounding environment of the glasses 10. The light intensity sensor 32 detects the intensity of light in the surrounding environment of the glasses 10. As the ambient light color sensor 31, for example, an image sensor is used. For the light intensity sensor 32, for example, a photodiode or the like is used. The ambient light color sensor 31 and the light intensity sensor 32 do not necessarily need to be physically separated, and one physical means may serve as both sensors. For example, using an image sensor that acquires an image, the color of the ambient environment light is detected based on the color information of the acquired image, and the light intensity of the ambient environment light is determined based on the signal intensity information of the acquired image. It may be detected.

  The temperature sensor 33 measures the temperature of the surrounding environment. The humidity sensor 34 detects the humidity of the surrounding environment. The number and type of sensors included in the surrounding environment detection means 13 are arbitrary, and it is not necessary to have all of the ambient light color sensor 31, the light intensity sensor 32, the temperature sensor 33, and the humidity sensor 34. Moreover, you may have a sensor different from these sensors.

  The control unit 12 mainly controls the color of the illumination light emitted by the light emitting unit 50 based on the color of the ambient environmental light detected by the environmental light color sensor 31. The control means 12 controls the color of the illumination light based on the color of the ambient environment light, thereby making the illumination light applied to the wearer who is the user inconspicuous. For example, when the ambient environment light has a reddish color, the control unit 12 controls the illumination light emitted by the light emitting unit 50 to a reddish color. Instead of or in addition to controlling the color of the illumination light, the control means 12 determines the intensity of the illumination light emitted by the light emitting unit 50 based on the color of the ambient environment light detected by the ambient light color sensor 31. You may control.

  The control unit 12 mainly controls the intensity of the illumination light emitted from the light emitting unit 50 based on the intensity of the ambient environment light detected by the light intensity sensor 32. The control means 12 controls the intensity of the illumination light based on the intensity of the ambient environment light, thereby suppressing the illumination light applied to the wearer from being too conspicuous. For example, when the intensity of the ambient environment mirror light is low, the control unit 12 reduces the intensity of the illumination light. For example, when the intensity of the ambient environment mirror light is high, the control unit 12 increases the intensity of the illumination light. In order to prevent the illumination light from becoming too conspicuous and unnatural when the surroundings are close to darkness, for example, when the ambient light intensity is lower than the threshold (first threshold). The irradiation of illumination light may be stopped. On the other hand, the control means 12 is too bright in the surroundings, for example, the ambient light intensity is greater than a threshold value (second threshold value, the second threshold value is greater than the first threshold value). If it is high, the illumination light irradiation may be stopped because it is hardly visible even when the illumination light is irradiated. Instead of or in addition to controlling the intensity of the illumination light, the control means 12 controls the color of the illumination light emitted by the light emitting unit 50 based on the intensity of the ambient environment light detected by the light intensity sensor 32. May be.

  The control unit 12 controls at least one of the color of illumination light and the intensity of illumination light emitted by the light emitting unit 50 based on the ambient temperature detected by the temperature sensor 33. For example, when the temperature of the surrounding environment is low, the control unit 12 controls the color of the illumination light to a cold color. For example, when the temperature of the surrounding environment is high, the control unit 12 controls the color of the illumination light to a warm color. The control unit 12 controls at least one of the color of illumination light and the intensity of illumination light emitted by the light emitting unit 50 based on the humidity of the surrounding environment detected by the humidity sensor 34.

  The user state detection means 14 detects the state of the wearer. The user state detection unit 14 detects, for example, at least one of the color of the user's skin (skin), the distance between the face and the glasses 10, the body temperature, and the sweating state. The user state detected by the user state detection unit 14 is arbitrary and is not limited to the above. Instead of or in addition to the control of the illumination light based on the surrounding environment detected by the surrounding environment detection unit 13, the control unit 12 is configured so that the light emitting unit 50 is based on the user state detected by the user state detection unit 14. Control at least one of the color of the illumination light to be irradiated and the intensity of the illumination light. The user state detection unit 14 notifies the control unit 12 of the detected user state as numerical data and / or data such as a predefined level value.

  The user state detection unit 14 includes, for example, a skin color sensor 41, a distance sensor 42, a body temperature sensor 43, and a sweat sensor 44. The skin color sensor 41 detects the skin color of the wearer of the glasses 10. As the skin color sensor 41, for example, an image sensor is used. The distance sensor 42 measures the distance between the frame 101 and the wearer's face. The distance sensor 42 includes, for example, a range finder transmitter and a range finder receiver. The body temperature sensor 43 measures the body temperature of the wearer. The sweat sensor 44 detects the sweat of the wearer. The sweat sensor 44 detects that the wearer is sweating, for example, by measuring the reflectance of the skin surface of the wearer.

  The control means 12 mainly controls the color of the illumination light emitted by the light emitting unit 50 based on the skin color detected by the skin color sensor 41. The control means 12 controls the color of the illumination light based on the detected skin color, thereby suppressing the illumination light applied to the wearer who is the user from being noticeable. For example, the control unit 12 instructs the light emitting unit 50 to emit illumination light having a color close to the color of the user's skin. Instead of or in addition to controlling the color of the illumination light, the control means 12 determines the intensity of the illumination light emitted by the light emitting unit 50 based on the skin color of the wearer detected by the skin color sensor 41. You may control.

  The control means 12 mainly controls the intensity of the illumination light emitted by the light emitting unit 50 based on the distance between the glasses 10 detected by the distance sensor 42 and the wearer's face. The control means 12 controls the illuminance of the illumination light emitted to the wearer by controlling the intensity of the illumination light based on the detected distance. For example, when the detected distance is short, the control unit 12 lowers the intensity of the illumination light compared to when the distance is long. Instead of or in addition to controlling the intensity of the illumination light, the control means 12 controls the color of the illumination light emitted by the light emitting unit 50 based on the intensity of the ambient environment light detected by the distance sensor 42. May be.

  Based on the body temperature of the wearer detected by the body temperature sensor 43, the control unit 12 controls at least one of the color of illumination light and the intensity of illumination light emitted by the light emitting unit 50. For example, when the body temperature is low, the control unit 12 controls the color of the illumination light to be whitish. For example, when the body temperature is high, the control unit 12 controls the color of the illumination light to a reddish color. The control unit 12 controls at least one of the color of illumination light and the intensity of illumination light emitted by the light emitting unit 50 based on the detection signal of the sweat sensor 44. For example, when the user sweats and the reflectance of the skin surface increases, the control means 12 reduces the intensity of the illumination light.

  FIG. 9 shows an operation procedure. The control means 12 determines whether or not the user wears the glasses 10 (step S1). For example, when the user performs an operation of wearing the glasses 10, the control unit 12 determines that the user has worn the glasses 10. For example, when the opening / closing sensor 15 detects that the temple 104 is opened, the control unit 12 determines that the user wears the glasses 10. Alternatively, the control unit 12 determines that the user wears the glasses 10 when the contact state sensor 16 detects close contact with the user's skin. The control means 12 may determine that the user wears the glasses 10 when the opening / closing sensor 15 detects the state where the temple 104 is opened and the contact state sensor 16 detects contact with the user's skin. Good. When it is determined that the user does not wear the glasses 10, the control unit 12 repeatedly executes Step S <b> 1 until the user wears the glasses 10.

  When the control means 12 determines that the glasses 10 are worn in step S1, the control function 12 turns on the beauty function and causes the light emitting unit 50 to irradiate the user's face with illumination light (step S2). After the user wears the glasses 10, the control means 12 detects that the motion sensor 17 detects that the eyeball faces in the direction associated with the illumination light irradiation, and the time in which the eyeball faces in that direction is determined in advance. When the above is continued, illumination light may be irradiated. Alternatively, if the light source module 110 (see FIG. 1) is provided with a switch for selecting on / off of the cosmetic function, the control means 12 detects the operation of the switch to detect the cosmetic function. The illumination light may be irradiated from the light emitting unit 50 to the user's face.

  The surrounding environment detection means 13 detects the surrounding environment of the glasses 10 (step S3). The user state detection means 14 detects the state of the user (wearer) wearing the glasses 10 (step S4). Step S3 and step S4 may be performed in parallel or sequentially. Based on the surrounding environment detected at step S3 and the user state detected at step S4, the control means 12 determines the illumination light irradiated to the user from the light emitting unit 50 (step S5). In step S5, the controller 12 determines, for example, at least one of the color and intensity of the illumination light.

  The control means 12 irradiates the illumination light determined in step S5 from the light emitting unit 50 toward the user (step S6). The light source 51 (see FIG. 4) included in the light emitting unit 50 includes, for example, a light emitting element capable of programming the light emission color and intensity. In step S6, the control unit 12 determines the color and color determined in step S5. Intense light is emitted from the light source 51. The light emitted from the light source 51 passes through the light guide member 52 and is irradiated to the user's face, mainly around the eyes. Steps S3 to S5 may be omitted, and illumination light having a predetermined color and intensity may be applied to the user's face in step S6.

  The control means 12 determines whether or not the illumination light stop condition is satisfied (step S7). For example, when the user removes the glasses 10, the control unit 12 determines that the illumination light stop condition is satisfied. More specifically, for example, when the opening / closing sensor 15 detects a state where the temple 104 is closed, the control unit 12 determines that the illumination light stop condition is satisfied, assuming that the user removes the glasses 10. Alternatively, the control unit 12 determines that the illumination light stop condition is satisfied if the user removes the glasses 10 when the contact state sensor 16 does not detect contact with the user's skin. For example, when the opening / closing sensor 15 detects a state where the temple 104 is closed and the contact state sensor 16 does not detect contact with the user's skin, the control unit 12 determines that the user has removed the glasses 10 and illuminates light. It may be determined that the stop condition is satisfied. Instead of the above, the control means 12 detects, for example, that the motion sensor 17 faces the predetermined direction associated with the stop of the illumination light, and the state in which the eyeball faces the direction is predetermined. It may be determined that the illumination light stop condition is satisfied if the illumination light continues for more than a predetermined time.

  When it is determined that the illumination light stop condition is satisfied in step S7, the control unit 12 turns off the cosmetic function and stops the illumination unit 50 from irradiating the illumination light to the user (step S8). If it is determined in step S7 that the illumination light stop condition is not satisfied, the process returns to step S3 and step S4, and the detection of the surrounding environment and the detection of the user state are continued. When at least one of the surrounding environment and the user state changes, the illumination light irradiated to the user is changed accordingly.

  In the present embodiment, the spectacles 10 includes a light emitting unit 50 that irradiates illumination light to the outside of a region where it is assumed that an opening of the eye of the wearer is present when the wearer is wearing the frame 101. The illumination light emitted from the light emitting unit 50 to the wearer can brightly illuminate a region corresponding to the illumination light irradiation region in the wearer's face. In the present embodiment, the light emitting unit 50 mainly irradiates illumination light to a region outside the eye opening. By brightly illuminating the periphery of the eyes, it is possible to make the vicinity of the eyes of the wearer wearing the glasses 10 brighter, and to improve the visual impression. In particular, the effect of making the wearer look younger can be obtained by brightly illuminating the vicinity of the eyes considered to have many fine lines.

  Here, in Patent Document 1, light having a wavelength and illuminance that promotes awakening action or the like is irradiated to the wearer's eyes. In Patent Document 1, for the purpose of suppressing the secretion of melatonin, light having a wavelength and illuminance that directly promotes an awakening action or the like is irradiated to the eyes of the wearer. Therefore, even if the glasses with a light emitting function described in Patent Document 1 are used, the effect of improving the appearance of the wearer wearing the glasses 10 described above cannot be obtained.

  In the present embodiment, it is preferable that at least one of the frame 101, the control unit 12, the light emitting unit 50, the lens 105, and the power source 11 is modularized, and these modules are configured to be replaceable. In this case, the configuration of the glasses 10 can be arbitrarily changed by arbitrarily changing the module. For example, the light source 51 of the light emitting unit 50 is modularized to prepare a plurality of light source modules that emit light of a plurality of colors, and the user selects a light source module that emits light of any color and attaches it to the glasses 10. It is possible.

  Next, a second embodiment of the present invention will be described. The configuration and appearance of the glasses with light emitting function according to the second embodiment of the present invention are the same as those described in the first embodiment shown in FIGS. This embodiment is different from the first embodiment in that a part of the illumination light emitted from the light emitting unit 50 to the wearer's face is reflected in the wearer's pupil. Other points may be the same as in the first embodiment.

  FIG. 10 is a view of the glasses 10 as viewed from the front in the present embodiment. The difference from FIG. 7 described in the first embodiment is that light 203 is reflected in the pupil portion of the wearer's eye 201 in this embodiment. In particular, the illumination light emitted from the light guide member 52 disposed in the lower part of the frame 101 is reflected in the wearer's pupil. In the lower part of the frame 101, the surface of the light guide member 52 is scratched, the amount of light leaking from that part is made larger than the other parts, and the light 203 is intentionally reflected in the wearer's eyes. It is also good to not. When the light 203 is reflected in the pupil, in addition to the effect of making the fine lines around the eye 201 inconspicuous when observed from the outside, the effect of making the pupil shine brightly can be obtained. .

  In the present embodiment, a part of the illumination light applied to the periphery of the eye of the wearer of the glasses 10 is reflected on the wearer's pupil. In the present embodiment, the wearer's eyes appear to shine, and the wearer's appearance can be further improved. Other effects are the same as those described in the first embodiment.

  In the present embodiment, an attachment that can be attached to and detached from the frame 101 of the glasses 10 may be attached to the frame 101. The glasses 10 and the attachment constitute a glasses system. The attachment has a light transmission part and a light shielding part. The light blocking portion blocks a part of the illumination light emitted from the light emitting unit 50 (light guide member) 52, and the light transmitted through the light transmitting portion is reflected on the wearer's pupil, so that it is reflected on the wearer's pupil. The shape of the light 203 is defined. By preparing a plurality of attachments having different shapes of light transmitting portions and replacing them, it is possible to reflect light 203 having an arbitrary shape on the wearer's pupil.

  Subsequently, a third embodiment of the present invention will be described. The glasses with a light emitting function of the present embodiment are different from the first embodiment in the configuration of the light emitting unit. Other parts may be the same as in the first embodiment. FIG. 11 shows a light emitting unit used in glasses with a light emitting function according to the third embodiment of the present invention. As shown in the figure, the light emitting unit 50 a includes a light source 51, a display panel 53, and a projection unit 54. It is preferable that the light emitting part 50a is disposed at each of both ends of the front connected to the temple 104, for example.

  The light source 51 irradiates the display panel 53 with light from the back side of the display panel 53, for example. As the display panel 53, for example, a liquid crystal display panel is used. The projection unit 54 projects the light emitted from the light source and transmitted through the display panel 53 onto the wearer's face as illumination light. The projecting unit 54 may include a lens system (magnifying lens system), and may enlarge and project the light emitted from the light source 51 and transmitted through the display panel 53 onto the face of the wearer. The light projected by the projection means 54 forms an image on the wearer's face. The projection means 54 irradiates illumination light to a portion different from the portion where the opening of the wearer's eye exists, preferably around the wearer's eye. It is particularly preferable that the projecting means 54 irradiates the wearer's eyes with illumination light.

  In the present embodiment, the control unit 12 controls the display panel 53. By controlling the display panel 53, the color and intensity of the light projected on the wearer's face change. For example, when the control means 12 irradiates the wearer's face with illumination light of a predetermined color and intensity, the display panel 53 may be omitted.

  Also in the present embodiment, the light emitting unit 50a irradiates the illumination light toward the outside of the region where the opening portion of the wearer's eye is assumed to be present when the wearer wears the eye. Also in the present embodiment, as in the first embodiment, the effect of improving the appearance of the wearer wearing the glasses 10 can be obtained.

The external device 60 is, for example, a personal computer, a smartphone, a tablet, a mobile phone, or a controller dedicated to glasses with a light emitting function. Various known wireless communication means can be used as the wireless communication means. The communication means 19 may be modularized and configured to be detachable and replaceable with respect to the temple 104 (see FIG. 1).

  The control unit 12 may acquire various types of information from the external device 60 through the communication unit 19 and may control the light emitting unit 50 based on the acquired information. Alternatively, the user may use the external device 60 as an input device for the user to input control content to the control means 12. The user may arbitrarily control the color of illumination light and the intensity of illumination light emitted from the light emitting unit 50 to the wearer using the external device 60.

  For example, the user may operate the external device 60 to give an instruction to turn on or off the cosmetic function in the glasses 10 to the control unit 12 and arbitrarily switch the cosmetic function on and off. Alternatively, the user may operate the external device 60 to give the control means 12 information regarding the gender of the wearer of the glasses 10. The control means 12 holds different control contents for each gender, and may control the light emitting unit 50 according to the control contents corresponding to the gender given by the user.

  In each of the above embodiments, the light source 51 has been described as an example of a self-luminous element such as an LED. However, the present invention is not limited to this. The light source 51 may use ambient light as its light source. For example, a light input device that reflects or partially transmits ambient light may be used as the light source 51. When the ambient light is used as a light source of illumination light that irradiates the wearer's face, power supply to the light source 51 is not necessary.

  The lens 105 constituting the glasses 10 does not necessarily have a vision correction function. A plate-like member made of a light-transmitting material may be used as the lens 105. Alternatively, the lens 105 itself may be omitted, and the glasses 10 may be used in a state where the lens 105 is not attached.
