The second light source 120 is realized by a light emitting element. The second light source 120 emits visible light along the direction 122 in which the light emitting surface is directed. The second light source 120 has a color temperature of, for example, 10000K-30000K.

Furthermore, under certain conditions, the ratio of the second material to the first material was 60 ppm to 120 ppm, with the most preferable results being obtained.

Also, under certain conditions, the crystallite diameter of the second material was most preferably 15 nm to 250 nm.

The receiving unit 150 receives a control signal transmitted by a remote controller 200 described later, and outputs the received control signal to the control unit 160.

The control unit 160 acquires the control signal output from the receiving unit 150, and controls lighting or extinguishing of each of the first light source 110, the second light source 120, and the third light source 130 based on the acquired control signal.

The housing 170 is coated with a material that can absorb incident light on the inside of the housing 170. Specifically, the inside of the housing 170 is black, and the absorption coefficient in the visible range is higher than 70%, preferably higher than 90%, more preferably higher than 95%, and most preferably higher than 97%. It is also coated with high material.

The coating on the inside of the housing 170 is the light directly coming in the light irradiated by the first light source 110, the light reflected by the scattering member 140 in the light irradiated by the first light source 110, the light irradiated by the first light source 110 The purpose is to absorb light and the like scattered by the scattering member 140 among the light. In the coating on the inside of the housing 170, the light directly emitted from among the light emitted by the second light source 120, the light reflected from the scattering member 140 among the light emitted from the second light source 120, the second light source 120 It aims at absorbing the light etc. which were scattered by scattering member 140 among the irradiated light. In the coating on the inside of the housing 170, the light directly emitted from among the light emitted by the third light source 130, the light reflected by the scattering member 140 from the light emitted by the third light source 130, and the third light source 130 It aims at absorbing the light etc. which were scattered by scattering member 140 among the irradiated light. In addition, the coating on the inside of the housing 170 is intended to absorb the light transmitted through the scattering member 140 and the like among the light coming from the outside of the housing 170.

The direction of the light emitted by the first light source 110, the direction of the light emitted by the second light source 120, and the direction of the light emitted by the third light source 130 will be described. The first light source 110 emits light in the direction 112 in which the light emitting surface is directed. The second light source 120 emits light in the direction 122 in which the light emitting surface is directed. The third light source 130 emits light in the direction 132 in which the light emitting surface is directed.

In describing the light emitting surface facing direction 112, the light emitting surface facing direction 122, and the light emitting surface facing direction 132, coordinate axes are defined. Two directions parallel to the ground surface and orthogonal to each other are taken as an X-axis and a Y-axis. Further, the vertical direction perpendicular to the X axis and the Y axis is taken as the Z axis. One of the long side surfaces of the scattering member 140 is mounted parallel to the X axis and the Y axis so as to be seen through the opening 171 of the housing 170.

The direction 112 in which the light emitting surface of the first light source 110 is directed is the Z-axis direction. The angle θ between the direction 122 directing the light emitting surface of the second light source 120 and the vertically upward direction (−Z axis direction) from the center of the scattering member 140 is 10 degrees or more and less than 90 degrees. It is more preferable that θ be a direction of 60 degrees or more. In addition, the second light source 120 is installed at a position where it can be viewed only from a position 2 m or more above the ground which is taller than a typical person.

Preferably in the direction of In the present embodiment, a direction perpendicular to the Z axis and going to a plane different from the plane including the long side of the scattering member 140 is taken as the X axis.

(Example of lighting of lighting device)
The control unit 160 controls the lighting of the first light source 110 and the second light source 120, the control of lighting the first light source 110, the second light source 120, and the third light source 130, and the second light source 120 and the third light source 130. Switch between control and lighting. Specifically, the control unit 160 reproduces the situation where the sun is visible in the blue sky by turning on the first light source 110 and the second light source 120, and the first light source 110, the second light source 120, and the third light source 130 By lighting up, the situation where the sun is seen at dusk is reproduced, and by lighting up the second light source 120 and the third light source 130, the situation of dusk is reproduced.

FIG. 2: is a figure which shows the example of illumination of the illuminating device of this embodiment (the 1). In FIG. 2, the first light source 110 and the second light source 120 indicate that light is emitted by not filling them. In addition, the third light source 130 indicates that light is not irradiated by being filled.

The control unit 160 determines control information such as an instruction included in the control signal output by the receiving unit 150. When the control signal includes an instruction to reproduce the situation where the sun is seen in the blue sky, the control unit 160 supplies the power to the control line 114 to cause the first light source 110 to emit visible light, and the control line The second light source 120 is irradiated with visible light by supplying power to 124. The control unit 160 does not supply power to the control line 134 when the control signal includes an instruction to reproduce the situation where the sun is seen in the blue sky. For this reason, the third light source 130 does not emit visible light. Here, the light amount ratio between the light amount of the light emitted by the first light source 110 and the light amount of the light emitted by the second light source 120 is 1: 0.01-2 and more preferably 1: 0.1-1. It is.

The light irradiated in the direction 112 in which the first light source 110 directs the light emitting surface is Rayleigh-scattered by the scattering member 140. The light scattered by the scattering member 140 looks blue because the scattering member 140 scatters particularly short-wavelength blue light particularly strongly. Therefore, the blue sky can be reproduced by the light irradiated from the opening 171 through the scattering member 140 of the lighting device 100. Here, the blue light emitted by the second light source 120 emphasizes that the light emitted by the first light source 110 looks blue as it is Rayleigh-scattered by the scattering member 140. Furthermore, the light emitted by the first light source 110 looks like the sun through the scattering member 140. For this reason, the light irradiated from the opening 171 through the scattering member 140 of the lighting apparatus 100 can reproduce the sun. Therefore, it is possible to reproduce the situation where the sun is seen in the blue sky by the light emitted from the opening 171 of the lighting device 100. Here, the illuminance of the light emitted from the opening 171 through the scattering member 140 is 2000 lx-20000 lx, and more preferably, 5000 lx-15000 lx.

FIG. 3: is a figure which shows the example of illumination of the illuminating device of this embodiment (the 2). In FIG. 2, the first light source 110, the second light source 120, and the third light source 130 indicate that light is emitted by not being filled.

The control unit 160 supplies power to each of the control line 114, the control line 124, and the control line 134 when the control signal output from the receiving unit 150 includes an instruction to reproduce the situation where the sun is seen at dusk. The first light source 110, the second light source 120, and the third light source 130 are caused to emit visible light. Here, the light amount ratio between the light amount of the light emitted by the first light source 110, the light amount of the light emitted by the second light source 120, and the light amount of the light emitted by the third light source 130 is 1: 0.01-2: 0. It is preferable to change in the range of 1-12, and more preferable to change in the range of 1: 0.1-1: 1-6.

The light irradiated in the direction 112 in which the first light source 110 directs the light emitting surface is Rayleigh-scattered by the scattering member 140. Since the scattering member 140 causes the short wavelength blue light to be strongly scattered as compared to the long wavelength red light, the light scattered by the scattering member 140 Rayleigh looks blue. Therefore, the blue sky can be reproduced by the light irradiated from the opening 171 through the scattering member 140 of the lighting device 100. Here, the blue light emitted by the second light source 120 emphasizes that the light emitted by the first light source 110 looks blue as it is Rayleigh-scattered by the scattering member 140. However, since the amount of light emitted by the first light source and the second light source is lower than that emitted by the third light source 130, the influence of the light emitted by the third light source 130 is increased.

The light irradiated in the direction 132 in which the third light source 130 faces the light emitting surface propagates in the X axis direction while repeating total reflection inside the scattering member 140. Of the propagating light, blue light having a short wavelength is Rayleigh-scattered by the scattering member 140, and is irradiated mainly in the perpendicular direction (Z-axis direction) to the light incident surface. On the other hand, long-wavelength red light is less likely to be Rayleigh scattering and propagates in the X-axis direction. Since the light irradiated by the third light source 130 and the light scattered by the scattering member 140 appear to be red, dusk can be reproduced.

In addition, the light emitted by the first light source 110 looks like the sun through the scattering member 140. Therefore, the sun can be reproduced by the light emitted from the lighting device 100. Therefore, the situation where the sun is seen at dusk can be reproduced by the light irradiated from the opening 171 through the scattering member 140 of the lighting apparatus 100. Here, the illuminance of light emitted from the opening 171 through the scattering member 140 is 10 lx to 1000 lx, and more preferably 25 lx to 100 lx.

FIG. 4 is a diagram showing an illumination example (No. 3) of the illumination device of the present embodiment. In FIG. 4, the first light source 110 indicates that light is not irradiated by being filled. In addition, the second light source 120 and the third light source 130 indicate that light is emitted by not filling them.

The control unit 160 supplies power to the control line 124 and the control line 134 when the control signal output from the receiving unit 150 includes an instruction to reproduce the dusk state, thereby the second light source 120 and the second light source 120 The third light source 130 is made to emit visible light. The control unit 160 does not supply power to the control line 114 when the control signal includes an instruction to reproduce the dusk situation. For this reason, the first light source 110 does not emit visible light. Here, the ratio of the light amount of the light emitted by the second light source 120 to the light amount of the light emitted by the third light source 130 is preferably changed in the range of 1: 0.01-1, 1: 0.05 It is more preferable to change in the range of -0.5.

The light irradiated in the direction 122 in which the second light source 120 directs the light emitting surface is Rayleigh-scattered by the scattering member 140. The light scattered by the scattering member 140 looks blue because the scattering member 140 scatters particularly short-wavelength blue light particularly strongly. The light emitted in the direction 132 in which the third light source 130 faces the light emitting surface propagates in the X axis direction while repeating total reflection inside the scattering member 140. Of the propagating light, light having a short wavelength is Rayleigh-scattered by the scattering member 140, and is irradiated mainly in the perpendicular direction (Z-axis direction) to the light incident surface. On the other hand, long-wavelength red light is less likely to be Rayleigh scattering and propagates in the X-axis direction. Since the light irradiated by the third light source 130 and the light scattered by the scattering member 140 appear to be red, dusk can be reproduced. Here, since the light amount of the light emitted by the second light source is lower than the light emitted by the third light source 130, the influence of the light emitted by the third light source 130 is increased. Therefore, it is possible to reproduce the dusk by the light irradiated from the opening 171 through the scattering member 140 of the lighting device 100.
