LIGHT SOURCE UNIT AND LIGHTING DEVICE

摘要

PROBLEM TO BE SOLVED: To reduce a thickness of a translucent cover of a light source unit.SOLUTION: In a light source unit 200 of a lighting device 100, an optical receiver 220 has a light receiving surface 221 for receiving a signal from a remote controller. An attachment plate 230 has a first attachment surface 231 and a second attachment surface 232 which is a rear surface of the first attachment surface 231. A light source module 210 is attached to the first attachment surface 231. A power source device 250 and the optical receiver 220 are attached to the second attachment surface 232. A translucent cover 240 is attached to the attachment plate 230 and covers the first attachment surface 231 of the attachment plate 230. An opening window 233 is formed at the attachment plate 230. The opening window 233 penetrates through the first attachment surface 231 and the second attachment surface 232 of the attachment plate 230 and causes the light receiving surface 221 of the optical receiver 220 to face the translucent cover 240.SELECTED DRAWING: Figure 6
