Abstract (en)
According to one embodiment, a lamp includes a lamp main body having a radiation opening on one end side and a base on the other end side, and a luminous body which is provided in the lamp main body so that radiated light of a semiconductor light emitting element is emitted from the radiation opening. In addition, the lamp further includes a lighting unit which is accommodated on the other end side of the lamp main body, and turns on the semiconductor light emitting element; a cylindrical reflecting body which reflects the radiated light of the semiconductor light emitting element, and emits from an emission port to the radiation opening side; and a light-transmissive cover which is attached to the one end side of the lamp main body so as to cover the radiation opening. In addition, the lamp further includes a filter which is formed in a light-transmissive plate shape, is mixed with a color rendering agent, includes a planar portion facing the emission port, and an rugged portion in a region on the outer peripheral side of the planar portion, and is provided between the reflecting body and the cover.
