When installing the filter 3, a gap is removed from the beginning to dissipate heat inside the device, or a heat radiation hole 4 is provided in the filter frame 2 as shown in FIG. 3. In other words, when attaching the filter frame 2 with the filter 3 attached to the front of the lighting fixture body 1, if the filter frame 2 is sealed, the temperature inside the lighting fixture body 1 will rise and have an adverse effect. It is necessary. The filter frame 2 is formed into a ring shape, and has a large opening 8 formed in the front surface, and the filter 3 is attached to fit into this opening 8. A plurality of heat dissipation holes 4 are bored around the front side of the filter frame 2, and an elastic mounting spring 9 is provided from the front side to the rear side. A dogleg-shaped locking portion 9a is formed. The direct light from the lamp escapes through the heat radiation hole 4 of the filter frame 2, and when a Daicool color filter is installed as the filter 3, the complementary color of the transmitted light is reflected and exits through the heat radiation hole 4, so the ceiling There was a problem that it reflected on walls and was unsightly. FIG. 3 shows a case where a die cool color filter is used as the filter 3, and shows a state in which when red is transmitted, blue, which is a complementary color, is reflected and this reflected light passes through the heat radiation hole 4.

られる。(Example) Hereinafter, an example of the present invention will be described with reference to the drawings. FIG. 1 shows a cutaway side view of a lighting device main body 1 of the present invention, in which a lamp 6 attached to a socket 10 is arranged at the center of the interior. Further, a reflecting plate 11 is provided around the lamp 6. Lighting equipment body 1
is rotatably attached to a mounting plate 7, and the mounting plate 7 is rotatably attached to a base 12. Case 13 that constitutes the outer shell of the lighting fixture body 1
The outer periphery of the front opening is formed to have a small diameter.
The engagement portion 3 at the rear of the filter frame 2 is attached to this narrow diameter portion.
A is designed to be fitted. Further, the locking portion 9a of the attachment spring 9 of the filter frame 2 engages with the fixing portion 14 of the lighting fixture body 1, and the filter frame 2 provided with the filter 3 is attached to the lighting fixture body 1.

放熱効果をも持たせることができる。 Here, a disc-shaped light shielding plate 5 having a hole 5a in the center is disposed between the filter 3 and the lamp 6, that is, between the front end surface of the case 13 and the rear part of the filter frame 2. The inner diameter of the hole 5a of the light shielding plate 5 is determined as follows. That is, the filter 3 is made of transparent glass (heat ray absorbing glass, etc.)
In the case of colored plate glass, the hole 5a has an inner diameter of D2 and intersects with the light shielding plate 5 on a straight line connecting the filament point O of the lamp 6 and the point A of the heat radiation hole 4 of the filter frame 2 . In addition, when the filter 3 is a die-cool color filter, the complementary color of the transmitted light is reflected, so the inner diameter D 1 should be set so that the light emitted from the filament is reflected on the filter 3 surface and does not go out from the heat radiation hole 4. The hole is called 5a. Therefore, the light from the lamp 6 hits the light shielding plate 5 and does not directly leak from the heat radiation hole 4, and the light from the lamp 6 that reflects the complementary color of the transmitted light and exits from the heat radiation hole 4 is blocked. The light is blocked by the plate 5 and does not leak from the heat radiation hole 4 even if it is reflected by the filter 3 surface. Therefore, heat radiation hole 4
In addition to preventing light leakage, the heat radiation holes 4 can also provide a heat radiation effect.

る。[Effects of the invention] As described above, the present invention improves the heat radiation of the filter frame in a lighting equipment in which a filter frame having heat radiation holes around the periphery and a filter attached to the front is attached to the front of the lighting equipment body. This is because a light shielding plate having a hole with an inner diameter that blocks direct light from the lamp leaking through the hole and reflected light reflected from the back of the filter is placed between the heat dissipation hole and the lamp and in the filter frame. A light-shielding plate having an inner diameter hole that blocks direct light from the lamp leaking from the heat radiation hole of the filter frame and reflected light reflected from the back of the filter is placed between the heat radiation hole and the lamp and in the filter frame. The light from the lamp is transmitted through the hole in the light-shielding plate through the filter, and the light from the lamp that is projected onto a part larger than the inner diameter of the hole in the light-shielding plate is blocked by the light-shielding plate, and the light from the lamp is filtered through the heat dissipation hole in the filter frame. Therefore, there is no light leakage, no reflection on the ceiling or walls, and
This has the effect of eliminating glare.
