Japanese Patent JP3847320

B1

An explosionproof light source device, enabling an increase in the cooling performance of a light source and a reduction in the number of parts. In the light source device (30), an inner wall member (50) formed of a first inner wall (51), a second inner wall (52), and a third inner wall is installed in a U-shaped casing (31), and a front wall (40) formed integrally with the forward part (42) of one side wall of the casing, the other side wall (60) of the casing, and a rear wall (70) are installed around the casing. The light source (21) is fitted to the inner surface (41c) of the front wall (40), and the heat of the light source (21) is radiated through the front wall (40). A circulation fan (29) is installed at the rear part (34) of the casing (31) forming the one side wall. By the operation of the circulation fan (29), air flows from the duct part (43) of the forward part (42) into the reflector (22) of the light source (21) to cool an illuminant (24) in the reflector (22), and the heated air is circulated along the periphery of the casing (31) and radiated from the other side wall (60) and the rear wall (70).
