Abstract
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.
