PROBLEM TO BE SOLVED: To provide a luminaire which eases restrictions on the layout of a power source and an optical sensor in a case housing the power source and the optical sensor and efficiently takes light into the optical sensor.SOLUTION: A luminaire (300) includes: an LED (3); a sensor window (101) which takes light thereinto; an optical sensor (71) which senses brightness of a surrounding area on the basis of the light taken from the sensor window (101); a lighting circuit (70) which controls lighting of a light emitting element on the basis of the brightness of the surrounding area sensed by the optical sensor (71); a power source box lower lid (72a) and a power source box upper lid (72b) which house the optical sensor (71) and the lighting circuit (70); and a cover (5) which covers the LED (3), the power source box lower lid (72a), and the power source box upper lid (72b). The power source box lower lid (72a) and the power source box upper lid (72b) have reflection parts which reflect the light taken from the sensor window (101) into the optical sensor (71).SELECTED DRAWING: Figure 1 |
