LUMINAIRE

摘要

PROBLEM TO BE SOLVED: To provide a luminaire improving indoor illuminance while improving photosensitivity.

SOLUTION: The luminaire 10 includes: a device body 11 constituted so that light is also output to places other than a lower surface from the inside of the device; a discharge lamp 13 formed in a planar shape by bending an arc tube 22; a light reception portion 19 including a light receiving element 20 for receiving a radio light signal transmitted from a remote control device 21 under the discharge lamp 13; and a lighting device 14 performing lighting control of the discharge lamp 13 in response to the radio light signal received by the light reception portion 19. A reflecting plate 17 is provided between a light-emitting part 22 of the discharge lamp 13 and the light reception portion 19, wherein the reflecting plate is formed to have an angle so that light from the discharge lamp 13 does not directly enter the light receiving element 20 and reflected light is also irradiated on places other than the just under the device body 11.
