Luminaire

摘要

According to one embodiment, a floodlight includes at least one light-emitting part, a thermal radiator, a reflector, and an adapter part attachable to and detachable from the thermal radiator. The light-emitting part includes an LED element. The thermal radiator is thermally connected to the light-emitting part. The reflector is provided on the thermal radiator, and controls luminous intensity distribution from the light-emitting part. The adapter part includes an extension reflector. The extension reflector is continuous with the reflector in a state where the adapter part is attached to the thermal radiator and, together with the reflector, controls the luminous intensity distribution from the light-emitting part to provide a luminous intensity distribution angle narrower than the reflector.

1. A luminaire comprising:
at least one light-emitting part; a thermal radiator thermally coupled to the light-emitting part; a reflector that is attached to the thermal radiator and shapes luminous intensity distribution of light emitted from the light-emitting part; and an adapter part attached to the thermal radiator and including an extension reflector that is continuous with the reflector and, together with the reflector, shapes the luminous intensity distribution of the light emitted from the light-emitting part to provide a luminous intensity distribution angle narrower than a luminous intensity distribution angle of the reflector without the extension reflector.
