OPTICAL FIBER IRRADIATION APPARATUS

摘要

PURPOSE: An optical fiber light emission device is provided to emit light including enough brightness by enabling an LED(Light Emitting Diode) light source to effectively emitting light to an object through a lens. CONSTITUTION: An LED light source is arranged on an LED substrate(15). A lens(19) collects light emitted from the LED light source. An optical fiber(20) guides light emitted from the LED light source through a lens(18). An optical fiber holder(25) maintains an optical fiber. The optical fiber faces to a light receiving surface through a spacer arranged between the lens and the optical fiber. When a front surface of the LED light source or the lens is fixed at the optical fiber holder, the spacer controls a distance between the optical fiber and the front surface of the LED light source.
