PROBLEM TO BE SOLVED: To solve such a problem that lighting equipment using a light emission diode (LED) has uneven brightness on a light emission surface (transmission surface).SOLUTION: Lighting equipment 100 includes a reflection surface 50 which reflects light, a transmission surface 60 which transmits light and a plurality of LEDs 70 which are arranged between the reflection surface 50 and the transmission surface 60 and emit light toward the transmission surface 60. Therein, the plurality of LEDs 70 are arrayed in a matrix shape, heights from the reflection surface 50 of the LEDs 70 adjoining each other at least in either direction of row direction and column direction are differentiated from each other and, thereby, the evenness of brightness of the transmission surface 60 is improved. |
