A lighting unit according to one embodiment includes a board, a support member, and a plurality of heat radiation fins. A light emitting element is disposed on a first surface of the board. The support member has an interior surface on which a second surface of the board that is opposite to the first surface is disposed to be in contact therewith to enable heat conduction from the board to the support member. The heat radiation fins are disposed on an exterior surface of the support member substantially parallel with each other and with a clearance between each other, and each having a flat shape that extends outwardly from the exterior surface.

Lighting unit and lighting device

According to one embodiment, a light-emitting unit includes a light-emitting section, a diffusion cover, and a reflector. The light-emitting section includes an LED element. The diffusion cover diffuses light emitted from the light-emitting section. The reflector controls the light diffused by the diffusion cover.

Light-emitting unit and luminaire

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.
