Detailed Description

To make the objects, technical solutions and advantages of the present application more clear, the technical solutions of the present application will be clearly and completely described below with reference to specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Technical solutions disclosed in the embodiments of the present application are described in detail below with reference to the accompanying drawings.

As shown in fig. 1 and fig. 2, an embodiment of the present application discloses an optical lens 100, and a light distribution effect can be provided for a light source 200 by using the optical lens 100. The optical lens 100 may be made of a material with relatively good light transmittance, such as glass or resin, so as to ensure that the optical lens 100 does not substantially block light.

The optical lens 100 has a first end surface 110 and a second end surface, wherein the first end surface 110 is used for cooperating with the light source 200, that is, in the using process of the optical lens 100, the light source 200 can be disposed at one side of the first end surface 110 of the optical lens 100, so that the light emitted from the light source 200 is incident into the optical lens 100 from the first end surface 110 of the optical lens 100, and the optical lens 100 is utilized to control the light emitted from the light source 200 to be emitted to the second end surface along the axial direction of the optical lens 100.

Specifically, the light source 200 may be a parallel light source, and the light source 200 may be disposed outside the first end surface 110, such that the first end surface 110 is a planar structure. In this case, the first end surface 110 may provide a transmission function for the light source 200, and ensure that the light emitted from the light source 200 can pass through the first end surface 110 and be emitted to the second end surface. Of course, the type of the light source 200 and the position relationship between the light source 200 and the first end surface 110 may be other ways, and may be determined according to the specific configuration of the first end surface 110.

In order to ensure that the optical lens 100 can provide optical effects for light, the second end face is provided with a plurality of optical structure components, and the plurality of optical structure components are adjacently distributed along a first direction perpendicular to the axial direction, so that the plurality of optical structure components are utilized to provide relatively large optical coverage for the second end face. The size of each optical structure component in the first direction and the number of the optical structure components distributed along the first direction can be flexibly determined according to actual requirements, and are not limited herein. Of course, in order to ensure that the optical lens 100 can substantially provide optical effects for light rays emitted to a certain region on the second end surface of the optical lens 100, optical structure components distributed along the first direction can be adjacent to each other and connected with each other, so that the optical structure components are distributed adjacently; further, the optical structure component can be distributed on the second end face of the optical lens 100, so that the light emitted to any position of the second end face can be controlled by the optical structure component.

Accordingly, in order to facilitate the optical structure assembly to be formed on the second end surface, the second end surface may be a planar structure, the outer edge of the second end surface may be in a regular shape such as a circle or a rectangle, and when there is a corresponding need, the outer edge of the second end surface may also be in an irregular shape, which is not limited herein. In addition, the optical structure assembly can be fixed on the second end surface by means of light-transmitting glue bonding and the like. In another embodiment of the present application, a plurality of optical structure components and a structure where the second end surface is located may be formed in an integrated manner, so that on one hand, the processing difficulty of the whole optical lens 100 is reduced, on the other hand, the transmission efficiency of light between the second end surface and the optical structure components may be improved, and the additional structure may be prevented from adversely affecting the propagation process of light between the second end surface and the optical structure components.

Based on the above optical structure assembly, further, as shown in fig. 1 and 3, each optical structure assembly includes a plurality of optical microstructures 170, the plurality of optical microstructures 170 in each optical structure assembly are adjacently distributed along a second direction, the second direction is perpendicular to both the axial direction of the optical lens 100 and the first direction, that is, the first direction, the second direction and the axial direction of the optical lens 100 can be three coordinate axes of a rectangular spatial coordinate system, more specifically, the first direction can be a direction Y in fig. 3, the second direction can be a direction X in fig. 3, and the axial direction of the optical lens 100 can be a direction Z in fig. 2. By connecting the plurality of optical microstructures 170 in each optical structure assembly end to end in the second direction, the plurality of optical microstructures 170 in each optical structure assembly can be ensured to be adjacently distributed in the second direction, so as to ensure that light rays emitted to any position on any optical structure assembly can be controlled by the optical microstructures 170.

The optical microstructures 170 are arranged in a protruding manner relative to the second end face, and the light-emitting surface of each optical microstructure 170, which faces away from the second end face, is an arc-shaped line segment in a figure cut by any first plane perpendicular to the first direction, and the parameters of each arc-shaped line segment are the same. The parameters of the arc line segment are the line type of the arc line segment, and specifically include the radian of the corresponding position of the arc line segment, the overall configuration of the arc line segment and the like. Under the condition of adopting the technical scheme, after the light rays with the same direction are incident to the corresponding position of any optical microstructure 170 at the same incident angle, the optical microstructures 170 can provide the same optical action effect for the light rays, so that the shape and the parameters of the light spots formed after the light distribution of the different optical microstructures 170 are the same or basically the same, and then, as shown in fig. 5 and 6, after the light spots formed by the light distribution of the plurality of optical microstructures 170 are mutually superposed, the formed superposed light spots can still be ensured to be similar to the shape of a single light spot, and the illumination effect is improved.

It should be noted that the protruding direction of any position on the arc line segment of each optical microstructure 170 cut by the first plane is a state protruding out of the optical microstructure 170, so as to ensure that the light distributed by any optical microstructure 170 can generate a diffused effect.

Further, as shown in fig. 3, in the process of arranging the plurality of optical microstructures 170, a pattern obtained by cutting two adjacent optical structure assemblies by a second plane perpendicular to the second direction includes a cross section of at least one optical microstructure 170, and the plurality of optical microstructures 170 of each of the two adjacent optical structure assemblies are arranged in a staggered manner in the second direction. That is, the plurality of optical microstructures 170 included in two adjacent optical structure assemblies are not arranged in a row.

In more detail, taking two sets of optical structure assemblies as a first optical assembly and a second optical assembly respectively as an example, a projection of any optical microstructure 170 in the first optical assembly in the first direction is at least simultaneously located on two adjacent optical microstructures 170 in the second optical assembly, and correspondingly, a projection of any optical microstructure 170 in the second optical assembly in the first direction is at least simultaneously located on two adjacent optical microstructures 170 in the first optical assembly. It should be noted that the optical microstructures 170 located at the two side edges in each of the first optical assembly and the second optical assembly may not be absolutely consistent with the above description due to the location of the optical microstructures 170, which is a relatively special case, but most of the optical microstructures 170 in the first optical assembly and the second optical assembly are consistent with the above description.

In the case that the plurality of optical microstructures 170 of two adjacent optical structure assemblies are staggered along the second direction, the positions of the cross sections of the second plane affect the positions of the cross sections of the two adjacent optical structure assemblies, so that the patterns cut by the second plane may include the cross sections of one or two optical microstructures 170.

Of course, in order to ensure that the light distribution effect of each optical structure assembly is similar, the sizes of the plurality of optical microstructures 170 in each optical structure assembly in the first direction may be equal. More specifically, the optical microstructures 170 may have a size of 0.37 to 0.5mm in the first direction. In addition, for the dimension of the plurality of optical microstructures 170 in the second direction in each optical structure assembly, the dimensions of the different optical microstructures 170 in the second direction may not be equal according to practical situations.

In another embodiment of the present application, the sizes of the plurality of optical microstructures 170 in each optical structure assembly in the second direction may be equal to each other, so as to further improve the light distribution consistency of the plurality of optical microstructures 170 in the same optical structure assembly; moreover, the size of any optical microstructure 170 in any optical structure assembly in the second direction can be made equal, so as to achieve the purpose of improving the illumination effect of the superimposed light spots formed after the light distribution of the plurality of optical microstructures 170 on the optical lens 100.

The embodiment of the present application discloses an optical lens 100, and the optical lens 100 can be applied to an optical module. The optical lens 100 can make the light emitted from the light source 200 disposed at the side of the first end surface 110 of the optical lens 100 emit to the second end surface thereof along the axial direction of the optical lens 100, so that the light is perpendicularly incident on the second end surface. Meanwhile, the second end face is provided with a plurality of optical structure assemblies which are adjacently distributed along the first direction, each optical structure assembly comprises a plurality of optical microstructures 170 which are adjacently distributed along the second direction, and the light emergent face of each optical microstructure 170 is an arc-shaped curved face which is outwards convexly arranged, so that each optical microstructure 170 can distribute light for the light emitted from the second end face, the light can generate a diffusion effect, and the irradiation range of the light is enlarged.

Moreover, even if the light intercepting member 300 is disposed on the light emitting side of the optical lens 100 for obtaining better light shadow modeling when the optical lens 100 is applied to an optical module, the light intercepting member 300 can extend from the outside of the optical lens 100 to the light emitting side of the optical lens 100 along the second direction, and the first side of the light intercepting member 300 is parallel to the first direction, so that at least a portion of the optical microstructure 170 corresponding to the first side in each optical structure assembly is not covered by the first side, that is, the overlapping property of the light emitting area of the optical lens 100 can be better, and under the irradiation of the optical microstructure 170 adjacent to the first side 130 of the light intercepting member 300 in each of the plurality of optical structure assemblies, the shadow generated by the first side 130 can be dispersed, thereby ensuring that no shadow is formed on the irradiated surface at any position on the first side, preventing the light emitted by the light source 200 from having a ripple-shaped light spot formed on the side of the optical lens 100, and improving the illumination effect.

As described above, the specific structure of the first end surface 110 of the optical lens 100 may be related to the specific form of the light source 200, and in the above embodiment, the light source 200 may be a parallel light source. In the embodiment of the present application, the light source 200 may be a diffusion light source, in which case, in order to ensure that the optical lens 100 can provide the function of converging light rays for the diffusion light source 200 and outputting parallel light rays, optionally, as shown in fig. 1, the optical lens 100 is a bowl-shaped structural member, in which case, the side surface 130 connected between the first end surface 110 and the second end surface in the optical lens 100 is a reflective surface, so as to provide a reflective function for diffusing light rays towards the side surface 130 by using the reflective surface, and prevent the light rays from overflowing. In particular, the side 130 may be made reflective by providing the side 130 with a coating.

In the optical lens 100 with the above structure, the optical lens 100 is provided with the light source accommodating cavity 150, the light source accommodating cavity 150 is formed by recessing from the first end surface 110, the light source accommodating cavity 150 is used for accommodating the light source 200, and the inner wall of the light source accommodating cavity 150 can also provide a light distribution effect for the light source 200. Specifically, as shown in fig. 2, the inner wall of the light source accommodating chamber 150 includes an end wall and a side wall 151, the end wall includes a converging surface 152 formed to be concave toward the first end surface 110, and an outer edge of the converging surface 152 is connected to the side wall 151, in other words, the converging surface 152 is located in an area surrounded by the side surface 130. The converging surface 152 can provide a converging effect for the light, so that the part of the diffused light emitted by the diffusion type light source, which irradiates on the converging surface 152, can be converged by the converging surface 152, and after the light emitted by the light source 200 is converged by the converging surface 152, the light can be emitted to the second end surface along the axial direction of the optical lens 100. Specifically, the specific parameters of the converging surface 152 may be determined according to actual conditions, so as to ensure that it can provide a converging effect for the light irradiated by the diffusive light source 200 on the converging surface 152.

In order to improve the utilization rate of the light, the sidewall 151 may be a light-transmitting surface, so that the light irradiated on the side surface 130 by the diffusive light source can be transmitted out through the sidewall 151 and continuously transmitted to the side surface 130, the side surface 130 may provide a reflection effect for the light, and the light emitted from the sidewall 151 can be reflected by the side surface 130 and then emitted to the second end surface along the axial direction of the optical lens 100. Specifically, by making the parameters of the side wall 151 and the side surface 130 correspond to each other, it is ensured that the light emitted from the light source 200 toward the side wall 151 can be reflected by the side surface 130 and emitted toward the second end surface along the axial direction of the optical lens 100.

As described above, the end wall of the light source accommodating cavity 150 includes the converging surface 152, and optionally, the end wall of the light source accommodating cavity 150 includes only the converging surface 152, that is, any position on the end wall of the light source accommodating cavity 150 is recessed toward the side where the first end surface 110 is located, so as to provide a converging effect for light rays.

Considering that the intensity of the light emitted from the central position of the light source 200 is relatively high, in order to further improve the illumination uniformity of the light spot generated by the light source 200 through the optical lens 100, in another embodiment of the present application, as shown in fig. 2, optionally, the converging surface 152 is an annular structure, and the end wall further includes a diffusing surface 153, the diffusing surface 153 is disposed to protrude in a direction away from the first end surface 110, and the diffusing surface 153 is connected to the inner side of the converging surface 152, and the light received by the diffusing surface 153 can be diffused.

Specifically, in the end wall of the light source accommodating cavity 150, the area opposite to the edge is provided with a converging surface 152, the area opposite to the center is provided with a diffusing surface 153, the converging surface 152 protrudes towards the direction close to the first end surface 110, and the middle part of the diffusing surface 153 protrudes towards the direction close to the second end surface, so that the diffusing surface 153 is used for providing a diffusing effect for the light rays which are incident to the end wall from the light source 200 and are relatively centered, the converging surface 152 is used for providing a converging effect for the light rays which are incident to the opposite edge in the end wall from the light source 200, the uniformity of the light rays which are incident to the end wall from the light source 200 at any position on the second end surface is relatively high, and the brightness uniformity of the light irradiation area generated by the light source 200 through the optical lens 100 is improved.

Specifically, the size distribution ratio of the diffusing surface 153 and the converging surface 152 in the radial direction of the optical lens 100 may be determined according to actual parameters such as the size of the light source 200 and the distribution of light of the light source 200, and is not limited herein. Of course, in order to reduce the difficulty of processing the end wall of the light source accommodating cavity 150 in the optical lens 100, the converging surface 152 and the diffusing surface 153 may be formed together by integral molding.

In the above embodiment, the diffusing surface 153 may be formed such that the diffusing surface 153 protrudes with its center position toward the direction of the second end surface with reference to the edge thereof, in which case, if the diffusing surface 153 is cut by a plane passing through the axis of the optical lens 100, the cut pattern may include two arc segments connected to each other, the two arc segments are a first arc segment and a second arc segment respectively, and the two arc segments are connected to each other at a position relatively closer to the second end surface than the end of the two arc segments facing away from each other.

Optionally, the first arc-shaped segment and the second arc-shaped segment are both arcs, that is, the curvatures at any position on the first arc-shaped segment and the second arc-shaped segment are equal. In another embodiment of the present application, optionally, the curvature of the portion of the first arcuate segment proximal to the second arcuate segment is greater than the curvature of the portion of the first arcuate segment distal to the second arcuate segment. In other words, the curvature of the portion of the diffusion surface 153 corresponding to the first arc-shaped segment is larger as the portion is farther from the converging surface 152, and in the case of adopting this technical solution, the diffusion capability of the portion of the diffusion surface 153 corresponding to the first arc-shaped segment is stronger as the distance from the center of the light source 200 is smaller along the radial direction of the optical lens 100, so as to further improve the diffusion uniformity of the diffusion surface 153 on the light emitted from the center of the diffusion-type light source 200, and maximally improve the illumination uniformity of the light diffused by the diffusion surface 153 on the second end surface.

Similarly, the above technical idea can be adopted for the second arc segment, specifically, the curvature of the portion of the second arc segment close to the first arc segment is larger than the curvature of the portion of the second arc segment far from the first arc segment, so as to ensure that the portion of the diffusing surface 153 corresponding to the second arc segment has relatively better diffusing effect on the light source 200.

Alternatively, the curvatures of the first arc-shaped segment and the second arc-shaped segment at the corresponding positions may be different, and in order to improve the uniformity of the diffusion effect of the diffusion surface 153 in the circumferential direction of the optical lens 100, the curvatures of the first arc-shaped segment and the second arc-shaped segment at the corresponding positions may be made the same, in other words, the first arc-shaped segment and the second arc-shaped segment may be symmetrically arranged. Specifically, the specific size of the curvature of the first arc-shaped segment (and the second arc-shaped segment) at the corresponding position can be flexibly determined according to the light distribution of the light source 200, so that the diffusion surface 153 can provide a good diffusion effect for the light source 200.

Under the condition that the light source accommodating cavity 150 is provided, the sidewall 151 of the light source accommodating cavity 150 may be a truncated cone-shaped structure, and the diameter of the sidewall 151 is gradually reduced along the direction from the first end surface 110 to the second end surface, that is, the end with the relatively larger diameter in the sidewall 151 is located at the first end surface 110, and the end with the relatively smaller diameter in the sidewall 151 is located between the first end surface 110 and the second end surface, in this case, the sidewall 151 may provide a deflection function for the light, so that the light incident to the sidewall 151 can be deflected toward the direction close to the first end surface 110, a coverage area of the light is improved, a diffusion effect of the light incident from the light source 200 to the sidewall 151 in the optical lens 100 is relatively good, and a coverage area of the light emitted from the optical lens 100 through the second end surface is improved. Specifically, the difference between the respective diameters of the two opposite ends of the sidewall 151 may be determined according to the illumination area to be covered, and is not limited herein.

As described above, the surfaces of the optical microstructures 170 away from the first end surface 110 are all light-emitting surfaces, and the light-emitting surface of any optical microstructure 170 is an arc-shaped protruding structure. More specifically, a graph obtained by cutting the light emitting surface of any optical microstructure 170 by a first plane perpendicular to the first direction can satisfy an aspheric equation, and in this case, the illumination uniformity of the illuminated surface can be improved.

Further, the light emitting surface of any optical microstructure 170 may be cut by a first plane perpendicular to the first plane to satisfy the same aspheric equation, so as to maximize the illumination uniformity of the illuminated surface through the surface type design of the light emitting surface.

Based on the above embodiment, further, the connecting lines between the centers of the three optical microstructures 170 in two adjacent sets of optical structure assemblies may be equilateral triangles. Taking the first optical assembly and the second optical assembly in the above embodiments as an example, a connection line between respective centers of one optical microstructure 170 in the first optical assembly and two optical microstructures 170 adjacent to the optical microstructure 170 in the second optical assembly forms an equilateral triangle. In the case that the optical microstructure 170 is a structure formed by a uniform material, the center of the optical microstructure 170 may be the center of gravity thereof.

More specifically, the sizes of the plurality of (complete) optical microstructures 170 disposed on the second end surface in the first direction and the second direction are the same, and since the graphs of any optical microstructure 170 cut by the first plane perpendicular to the first direction all satisfy the same non-curved surface equation, the specific structures of any optical microstructure 170 are correspondingly the same. On this basis, the corresponding point locations on the three adjacent optical microstructures 170 in the two adjacent optical structural assemblies are taken, and the connecting lines between the three point locations form an equilateral triangle.

In the case of the above technical solution, as shown in fig. 4, when the optical lens 100 needs to be used together with the light intercepting member 300, because the optical microstructures 170 are arranged in a staggered manner, when a cut-off light spot is formed, as shown in fig. 8, it is possible to maximally prevent the light intercepting member 300 from completely blocking one (or some) optical microstructures 170 in the second direction, so that a wavy shadow is not easily generated in the light spot formed on the illuminated surface.

Based on the optical lens 100 disclosed in any of the above embodiments, as shown in fig. 7, an optical module is further disclosed in the embodiments of the present application, which includes the light source 200, the light-intercepting member 300, the bracket 400 and any of the above optical lenses 100, wherein both the light source 200 and the optical lens 100 are mounted on the bracket 400, so that the bracket 400 is used to provide a supporting function for the light source 200 and the optical lens 100. The bracket 400 may be formed of a relatively strong material such as plastic or metal, and the specific shape and size of the bracket 400 may be determined according to parameters such as the size and shape of the light source 200 and the optical lens 100, which are not limited herein. The light source 200 and the optical lens 100 may be fixed at corresponding positions of the bracket 400 by means of bonding or connecting members. In addition, in the process of assembling the optical module, the light source 200 may be located at a side where the first end surface 110 of the optical lens 100 is located, so as to ensure that the light emitted by the light source 200 can enter the optical lens 100 through the first end surface 110 of the optical lens 100 and exit from the second end surface of the optical lens 100.

The light intercepting part 300 is a device used for providing modeling for the illumination effect in the optical module, can be made of a lightproof material, and can enable the light intercepting part 300 to be a dark structural part such as black and the like, so that the light intercepting effect of the light intercepting part is improved. The light-intercepting member 300 may be fixed on the bracket 400, or may be fixed on other structural members such as the periphery of the bracket 400, and the relative fixed relationship between the light-intercepting member 300 and the optical lens 100 is ensured. Also, the light intercepting member 300 has a first side parallel to the first direction. In the process of assembling the light intercepting member 300 and the optical lens 100, as shown in fig. 4, the first side of the light intercepting member 300 may be extended from the outside of the optical lens 100 to the side of the optical lens 100 away from the light source 200 along the second direction, so that the light intercepting member 300 covers a part of each of the optical structural components in the optical lens 100.

In the above optical assembly, because the first side of the light intercepting member 300 is parallel to the first direction, and the light intercepting member 300 extends into the side where the second end surface of the optical lens 100 is located along the second direction, and meanwhile, the light emitting surfaces of the plurality of optical microstructures 170 in each optical structural assembly are all arc-shaped convex structures, each optical microstructure 170 has an effect of diffusing light, and under the condition that the optical microstructures 170 in each of the two adjacent optical structural assemblies are distributed in a staggered manner, the first side of the light intercepting member 300 can be prevented from generating shadows on the illuminated surface, and the illumination effect of the optical assembly is improved.

Of course, in the process of disposing the light intercepting member 300 and the optical lens 100, the light intercepting member 300 may only shield a small portion of the optical lens 100, so as to prevent light generated by the light source 200 from being excessively wasted, and improve the energy utilization rate while ensuring a relatively high illumination effect.

Based on the above optical modules, optionally, as shown in fig. 9 to 12, an embodiment of the present application further discloses a lamp, where the lamp includes a mounting frame 510 and a plurality of the above optical modules, the mounting frame 510 may be made of a material with relatively high structural strength, such as metal, and the plurality of optical modules may be fixed on the mounting frame 510 through a structure, such as a threaded connector, and the mounting frame 510 may be directly or indirectly fixed on a wall through a structure, such as an expansion bolt. Of course, the lamp may further include other structures such as a base 520, a light-transmitting structure may be disposed on the base 520 to receive and transmit light emitted from the optical modules, the mounting frame 510 may be fixed on the base 520, and the base 520 may be fixed on a mounted surface (a mounted member) through a connector.

A plurality of above-mentioned optical module can be arranged along first direction, and the respective optical lens 100 of arbitrary optical module partly all is sheltered from by light-cutting member 300 for lamps and lanterns can form a plurality of oval faculas that have the effect of cutting off, and the illumination effect of this kind of lamps and lanterns is better, and user experience is higher. Moreover, under the condition that the plurality of optical modules are distributed along the first direction, the same light intercepting member 300 can be used for providing shielding effect for all the optical modules, the assembling difficulty of the light intercepting member 300 is reduced, and the light intercepting consistency of the light intercepting member 300 which is a plurality of optical modules can be improved.

In the embodiments of the present application, the difference between the embodiments is described in detail, and different optimization features between the embodiments can be combined to form a better embodiment as long as the differences are not contradictory, and further description is omitted here in view of brevity of the text.
