摘要 |
A lighting device 1 includes a planar light-emitting panel 4 and a translucent material 5 disposed on a light-emitting surface side of the planar light-emitting panel 4. The planar light-emitting panel 4 has a light-emitting region 4A and a non-light-emitting region 4B. The translucent material 5 has a reflection part 51 in a region facing the non-light-emitting region 4B. Light emitted from the planar light-emitting panel 4 and guided into the translucent material 5 is reflected by the reflection part 51 and emitted to the front side of the non-light-emitting region 4B. Accordingly, the front side of the non-light-emitting region 4B does not become a dark section, so that it is capable of increasing the light irradiation region and giving the light irradiation surface having uniform illuminance even if the plural lighting devices 1 are arranged in a matrix form. |
