FLUORESCENT ENDOSCOPE SYSTEM HAVING TWO LIGHT SOURCES

摘要

PURPOSE: A fluorescent endoscope system having two light sources is provided to simplify a structure of a light source system and reduce the manufacturing cost by using a dual light source device including an arc lamp and a white light lamp. CONSTITUTION: A light guide fiber bundle(24) is used for illuminating a diagnosing object by using the white light or the exciting light. A light source is automatically selected by a variance of a mirror according to a predetermined condition of an exciting light source or a white light source. An arc lamp(1) is used as the light source of the exciting light. The arc lamp is installed at a detachable lamp assembly(3). The light of the arc lamp is transmitted to the light guide fiber bundle through an optical condenser and an optical filter. The detachable lamp assembly is inserted into a vertical linear antenna(22) of a lamp house(2). Both sides of an electric connector is fixed to the lamp house and the detachable lamp assembly. A fan is installed at the detachable lamp assembly. A ventilation path(29) is formed between an external wall and an internal wall of the lamp house. A white light lamp(4) is used as the light source of the white light. The white light lamp is connected to a power supply(6).
