LIGHT SOURCE DEVICE AND ENDOSCOPE APPARATUS USING THE SAME

摘要

A light source device includes: a light emission part in which a plurality of illuminants are arranged on a support body; a light guide member in which light emitted from the light emission part is introduced into an incidence surface at one end of the light guide member; and a light collecting member which is located between the light emission part and the light guide member. The light collecting member comprises a plurality of tapered columnar bodies tapered toward the incidence surface of the light guide member. The plurality of tapered columnar bodies are placed so that base end portions thereof are each opposed to an associated one of light emission surfaces of the illuminants. A light emission window is formed at a position of the device, which is opposed to the incidence surface of the light guide member.
