PROBLEM TO BE SOLVED: To sufficiently illuminate a monitoring object by infrared light, in a warehouse, a factory and the like.SOLUTION: A luminaire 1 includes: a light source part 2 having a white LED 21 for emitting white light; and a wavelength conversion part 3 constituted as a separate body from the light source part 2, and for converting the white light from the white LED 21 into infrared light. In this constitution, as the white light from the white LED 21 which has light emission intensity higher than a general infrared LED and which hardly deteriorates is converted into the infrared light, the infrared light with high luminance can be emitted stably for a long period of time. Thereby, in a warehouse, a factory and the like, a monitoring object can be sufficiently illuminated by the infrared light.SELECTED DRAWING: Figure 1 |
