PROBLEM TO BE SOLVED: To provide a luminaire capable of returning light leakage efficiently.SOLUTION: A luminaire is configured by: a mirror device M1; and a surface light emitting unit U1 laminated on the mirror device M1. The mirror device M1 is configured by: transparent substrates 1, 2; transparent electrode layers 3, 4; a transparent seal part 5; and electrolyte 6. The surface light emitting unit U1 is configured by: transparent substrates 11, 12 which are parallel with each other; a knurl 13; and a red LED element 14 provided at a light incident end F1. When the mirror device M1 and the surface light emitting unit U1 come into an ON state, in the surface light emitting unit U1, light emitted when the LED element 14 is turned ON is reflected at the knurl 13 from the light incident end F1, travels in a light guide plate while changing a reflection angle, and emits from a light emission surface F2 as brake lamp light L1. At this time, the light goes toward an in-vehicle side from the transparent substrate 12 below as light L2 but is reflected by the mirror device M1 and returned to a rear window W1. |
