Next, key portions of hall lantern 7 will be described with reference to fig. 3.
Fig. 3 is a sectional view showing a critical portion of the section at the line a-a of fig. 2.
As shown in fig. 3, one side surface of the upper reflector 14 is disposed at an angle of 90 ° or more with respect to the upper display 10. In the upper light source 12, at least the light emitting section is disposed inside the upper reflecting body 14.
In this state, the light emitting portion of the upper light source 12 emits light in a direction different from the direction of the upper display 10. Specifically, the light emitting portion of the upper light source 12 emits light toward the upper curved surface. The upper curved surface reflects the light efficiently. At this time, the upper curved surface controls the reflection direction of the light according to its curvature. As a result, the light is homogenized and directed toward the upper display 10. Then, the light is transmitted through the upper display 10 in a homogenized state. As a result, the luminance of the upper display 10 becomes uniform.
Although not shown, one side surface of the lower reflector 15 is disposed at an angle of 90 ° or more with respect to the lower display 11. In the lower light emitter, at least the light emitting section is disposed inside the lower reflector 15.
In this state, the light emitting portion of the lower light source 13 emits light in a direction different from the direction of the lower display 11. Specifically, the light emitting portion of the lower light source 13 emits light toward the lower curved surface. The lower curved surface efficiently reflects the light. At this time, the lower curved surface controls the reflection direction of the light according to its curvature. As a result, the light is homogenized and directed toward the lower display 11. Then, the light is transmitted through the lower display 11 in a homogenized state. As a result, the luminance of the lower display 11 becomes uniform.
According to embodiment 1 described above, the upper reflector 14 reflects light emitted from the upper light source 12 by the curved surface and irradiates the upper display 10. The lower reflector 15 reflects light emitted from the lower light source 13 by a curved surface and irradiates the lower display 11. Therefore, light can be dispersed efficiently. In hall lantern 7, light unevenness can be suppressed even if the number of components is small. Further, the hall lantern 7 can be provided with a small size and low cost.
The upper light source 12 emits light in a direction different from that of the upper display 10. For example, when one side surface of the upper reflector 14 is arranged at an angle of 90 ° with respect to the upper display 10, the upper light source 12 emits light in a direction along the rear surface of the upper display 10. The lower light source 13 emits light in a direction different from that of the lower display 11. For example, when one side surface of the lower reflector 15 is disposed at an angle of 90 ° with respect to the lower display 11, the lower light source 13 emits light in a direction along the rear surface of the lower display 11. Therefore, the hall lantern 7 can be made thin.
Further, the upper reflector 14 is formed of a highly reflective material. The lower reflector 15 is formed of a highly reflective material. Therefore, the reflectance of the upper reflector 14 and the reflectance of the lower reflector 15 can be improved. As a result, the luminance of the upper display 10 and the luminance of the lower display 11 can be improved.
Further, a plurality of display bodies may be arranged in the horizontal direction. Further, a plurality of display bodies may be arranged at intervals. Moreover, only 1 display may be used.
Further, the reflector may be surface-treated so as to efficiently reflect light.
The upper light source 12 may be disposed outside the upper reflector 14. The lower light source 13 may be disposed outside the lower reflector 15.
The upper light source 12 may be disposed above or below the upper reflector 14 on the rear side of the upper reflector 14. The lower light source 13 may be disposed above or below the lower reflector 15 on the rear side of the lower reflector 15.
Embodiment mode 2
Fig. 4 is a perspective view of a hall lantern which is a light-emitting device of an elevator in embodiment 2. Note that the same or corresponding portions as those in embodiment 1 are denoted by the same reference numerals. The description of this portion is omitted.
In embodiment 2, the 1 st wall 16a and the 2 nd wall 16b are connected to each other at an angle. For example, the 1 st wall 16a is perpendicular to the 2 nd wall 16 b.
The display 17 is provided corresponding to the 1 st wall 16a and the 2 nd wall 16 b. The display 17 is disposed at the intersection of the 1 st wall 16a and the 2 nd wall 16 b. Specifically, the display 17 includes a 1 st display unit 17a and a 2 nd display unit 17 b.
The 1 st display part 17a and the 2 nd display part 17b are continuously formed. The 1 st display part 17a and the 2 nd display part 17b are formed in a planar shape. The 1 st display unit 17a and the 2 nd display unit 17b are connected to each other at an angle. The 1 st display unit 17a is perpendicular to the 2 nd display unit 17 b. The 1 st display portion 17a is provided corresponding to the 1 st wall 16 a. The 2 nd display portion 17b is provided corresponding to the 2 nd wall 16 b.
Next, key portions of hall lantern 7 will be described with reference to fig. 5.
Fig. 5 is a sectional view showing a key portion of a section at the line B-B of fig. 4.
As shown in fig. 5, the light source 18 is disposed on the opposite side of the 1 st display unit 17a from the 2 nd display unit 17 b. In the light source 18, at least the light emitting section is disposed inside the reflector 19.
In this state, the light emitting portion of the light source 18 emits light toward the curved surface of the reflector 19. The curved surface reflects the light efficiently. At this time, the curved surface controls the reflection direction of the light according to its curvature. As a result, the light is directed to the 1 st display unit 17a and the 2 nd display unit 17b in a homogenized state. Then, the light is transmitted through the 1 st display part 17a and the 2 nd display part 17b in a homogenized state. As a result, the luminance of the 1 st display unit 17a and the luminance of the 2 nd display unit 17b become uniform.
According to embodiment 2 described above, the reflector 19 reflects light emitted from the light source 18 by the curved surface and irradiates the 1 st display unit 17a and the 2 nd display unit 17 b. Therefore, in the 1 st display part 17a and the 2 nd display part 17b, the unevenness of light can be suppressed.
Further, the light emitted from the light source 18 may be reflected by the curved surface of the reflector 19 and irradiated to 3 or more display portions. In this case, the unevenness of light can be suppressed in the 3 or more display portions.
Embodiment 3
Fig. 6 is a perspective view of a hall lantern as a lighting device of an elevator in embodiment 3. The same or corresponding portions as those in embodiment 1 are denoted by the same reference numerals. The description of this part is omitted.
In embodiment 3, the front panel 20 is substantially the same as the front panel 9 of embodiment 1. The display body 21 is substantially the same as the upper display body 10 or the lower display body 11 of embodiment 1.
Next, key portions of hall lantern 7 will be described with reference to fig. 7.
Fig. 7 is a sectional view showing a key portion of the section at the line C-C of fig. 6.
As shown in fig. 7, light source 22 is disposed on the back side of display body 21 above display body 21. In the light source 22, at least the light emitting section is disposed inside the reflector 23. The reflector 23 includes a plurality of bent portions 23 a. The curvature of the plurality of curved portions 23a is different from each other.
In this state, the light emitting portion of the light source 22 emits light toward the plurality of curved portions 23 a. The plurality of curved portions 23a efficiently reflect the light. At this time, the plurality of curved portions 23a control the reflection direction of the light according to their own curvature. As a result, the light is directed toward the display 21 without being homogenized. Then, the light passes through the display body 21 in an ununiformed state. As a result, the luminance of the display 21 is not uniform.
According to embodiment 3 described above, the curvature of the plurality of curved portions 23a differs from each other in the reflector 23. Therefore, the direction of light reflection and the amount of light can be changed. As a result, the luminance of the display 21 can be partially changed arbitrarily. For example, gradation can be given to the luminance of the display 21.
For example, when the curvature of the curved portion 23a is small, the amount of light collected is small, and the brightness of the corresponding portion in the display body 21 can be reduced. On the other hand, when the curvature of the curved portion 23a is large, the amount of light collected becomes large, and the brightness of the corresponding portion in the display body 21 can be increased.
For example, by adjusting the curvature of the curved portion 23a, light can be converged at a set point in the display body 21, and a luminance difference can be locally given to an arrow, a character, or the like. For example, the set point can be made darker in the display body 21.
Embodiment 4
Fig. 8 is a cross-sectional view showing a key part of a hall lantern which is a light-emitting device of an elevator in embodiment 4. Note that the same or corresponding portions as those in embodiment 1 are denoted by the same reference numerals. The description of this part is omitted.
As shown in fig. 8, the light emitting portion of the upper light source 12 emits light in a direction away from the upper display 10. Specifically, the light emitting portion of the upper light source 12 emits light toward the plane of the upper reflector 14. The plane reflects the light efficiently. The light is directed toward the upper display 10. Then, the light passes through the upper display 10. At this time, the upper display 10 has a gradual change in luminance.
Although not shown, the light emitting portion of the lower light source 13 emits light in a direction away from the lower display element 11. Specifically, the light emitting portion of the lower light source 13 emits light toward the plane of the lower reflector 15. The plane reflects the light efficiently. The light is directed toward the lower display 11. Then, the light passes through the lower display 11. At this time, the lower display 11 has a gradation in brightness.
According to embodiment 4 described above, the upper reflector 14 irradiates the upper display 10 with light emitted from the upper light source 12 by planar reflection. The lower reflector 15 reflects light emitted from the lower light source 13 in a plane and irradiates the lower display 11. Therefore, gradation can be provided to the luminance of the upper display 10 and the lower display 11. As a result, in hall lantern 7, light unevenness can be suppressed even if the number of components is small. Further, the hall lantern 7 can be provided with a small size and a low cost.
The structure of hall lantern 7 according to embodiments 1 to 4 may be applied to another lighting device installed in a hall or a car. For example, the structure of hall lantern 7 according to embodiments 1 to 4 may be applied to hall button 6, an indicator, and the like. In these cases, in the light emitting device, the unevenness of light can be suppressed.
