摘要:
A vehicle lamp includes a phosphor which receives laser light (excitation light) emitted from a semiconductor light-emitting element to emit visible light, a reflector which reflects the visible light (illumination light) emitted from the phosphor forward, and an absorbing member which absorbs excitation light regularly reflected by a surface of the phosphor. A metal plate on which the phosphor is disposed to be inclined to cause the excitation light regularly reflected by the surface of the phosphor to be incident on the absorbing member. An upper end portion of the reflector is disposed at a position lower than a vertical position of the phosphor to prevent the regularly reflected excitation light from being incident on the upper end portion.
