Abstract
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.
