PROBLEM TO BE SOLVED: To provide a luminaire capable of greatly changing an atmosphere of light in a space.SOLUTION: An LED light bulb 1, which is one example of a luminaire for emitting illumination light, includes: a first light-emitting part 10A constituted by a plurality of first LED elements 11A connected in series; and a second light-emitting part 10B constituted by a plurality of second LED elements 11B connected in series, and for emitting light in a light color different from that of the first light-emitting part 10A. A light distribution angle of the illumination light changes according to the switching of the light colors of the illumination light by selective lighting between the first light-emitting part 10A and the second light-emitting part 10B.SELECTED DRAWING: Figure 1 |
