However, in the method of forced cooling with a fan, dust in the air is also sent into the light source at the same time, and it adheres to the light source, reflector, light guide, etc., reducing the light output and shortening the life of the light source. It was. In order to reduce this inconvenience, some dustproof filters 40 are used as shown in FIG. 3. However, dust smaller than the mesh size of the dustproof filter 40 cannot be captured and enters the interior, and enters the light source section. Adhesion leads to a decrease in light quantity and a shortened life of the light source. In addition, if dust adheres to the surface of the dustproof filter 40 and becomes clogged, the air cannot be blown into the inside and cannot be cooled, so that the light source and its vicinity become hot, and the life of the light source and its accessories is shortened. Inconveniences such as failure or failure. If the frequency of failures is high, a great deal of labor is required for maintenance, which is costly and reduces medical efficiency. An object of the present invention is to solve such problems and to sufficiently protect the light source unit from dust and cool it so that it can be used in an optimal state at all times.
