PROBLEM TO BE SOLVED: To provide a projector capable of dealing with different light distribution angles while utilizing a common structure.SOLUTION: A projector 11 includes at least one light-emitting part 22, a radiator 21, a reflector 23, and an adaptor part 16 attachable/detachable to/from the radiator 21. The light-emitting part 22 is provided with an LED element 22a. The radiator 21 is thermally connected to the light-emitting part 22. The reflector 23 is mounted on the radiator 21 and controls light distribution from the light-emitting part 22. The adaptor part 16 is provided with an extension reflector 56. The extension reflector 56 is connected to the reflector 23 with the adaptor part 16 mounted on the radiator 21 and controls the light distribution from the light-emitting part 22 so as to have an angle narrower than that of the reflector 23 together with the reflector 23. |
