Abstract
In a semiconductor light-emitting device, light from a laser diode is output to the outside after the luminance of the light being enhanced. It includes a support body provided with lead terminals, one or more laser diodes mounted on the support body, a cylindrical reflector fixed to the support body to surround the laser diode(s) and provided with a light reflection surface formed on an inner surface thereof, and a cap placed to cover an opening distal end face of the reflector and held at an opening distal end part of the reflector, the cap being provided at a central part thereof with a solid fluorescent member including a fluorescent substance that is excited by the light from the laser diode and emits light different in colors from light emitted by the laser diode.
