Abstract:
1. A light-emitting device comprising: a disk shaped support body; a light-emitting element constituted by a laser diode mounted on the support body; a cylindrical reflector, having openings at opposite ends, fixed to the support body to close one of said opposite ends and provided with a light reflection surface on its inner surface surrounding the light-emitting element; and a cap having a wavelength conversion member positioned at an interior portion of the cap, and a translucent member surrounding the wavelength conversion member, the wavelength conversion member extending completely through the cap and emitting light having a wavelength different from that of the light emitted by the light-emitting element when irradiated with light from the light-emitting element, and the cap being placed on the reflector to cover the other one of said openings of the reflector, wherein the wavelength conversion member being held by the translucent member at its outer periphery, wherein a planar shape of the wavelength conversion member being substantially coincident with a cross-sectional beam pattern shape of emitted output light from the light-emitting element on an irradiated surface and is being evenly wavelength-converted.
