In the embodiment shown in FIG. 2, the present floodlight uses the vent hole 8 on the rear surface of the socket tube 2 as a mounting hole for the filter case 51, but the structure is not limited to this. A plurality of relatively small through holes are formed on the back surface of the filter case 51, and these small through holes constitute the ventilation hole 8, and the filter case 51 is made so as not to protrude to the front side of the collar 51a. It may be arranged so that the front opening of the socket 51 and the vent hole 8 of the socket cylinder 2 can communicate with each other.

In the above embodiment, the projector according to the present invention does not limit the attachment member of the filter case 51 to the collar 51a, but also includes a screw thread carved into the front outer peripheral surface of the filter case 51, and this screw thread portion used as the attachment member. Alternatively, the filter case 51 may be screwed into a screw hole provided in the socket tube 2 in advance.

本案投光器はこの様なものであるから下記効果

Since the filter cover 52 is made of an elastic material, it is easy to attach and detach from the filter case 51, and therefore, the moisture absorbing material can be easily replaced, and the filter cover 52 can be attached and detached with one hand. Replacement work at high places is less dangerous. Since the filter part 5 is located at an eccentric position on the rear surface of the socket tube 2 and the cord 31 can be inserted from the center of the socket tube 2, the twist of the cord 31 is small and the design is easy.
