[Industrial applications]

 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a filter mounting frame for mounting a filter in front of a reflector having a light source, in which a filter for adjusting color and illuminance of the light source is mounted.

[0002]

[Prior Art]

 FIG. 5 shows a conventional example of a luminaire having a filter mounting frame, and is a front view of a state in which a part is cut away and is shown in section. In this figure, a main body C for mounting a reflection mirror B equipped with a light source A is fixed to a frame E having a plurality of heat dissipation holes K by screws D, and a cylindrical outer periphery of the frame E is provided. A filter L is sandwiched between a tip G of a pressing spring F fixed to the inner surface of the wall I with a rivet H and a front wall J of the frame E.

[0003]

[Problems to be solved by the device]

 In such a conventional lighting fixture, since the frame body E for mounting the filter L is attached to the main body C, it is necessary to replace the frame body E every time the form of the lighting fixture is different. The internal light source A can be exposed from the outside through a plurality of heat dissipation holes K provided in the frame E, causing light leakage to the outside, which is a problem that the appearance is not very good. ..

In view of the above problems, the present invention uses a common frame for attaching a filter to reduce the manufacturing cost of the fixture even if the fixture has different shapes. The objective is to obtain a filter mounting frame for lighting fixtures that minimizes the amount of light that leaks from the light source to the outside of the fixture through a plurality of heat dissipation holes provided in the frame.

[0005]

Means for Solving the Problems In order to achieve the above object, a filter mounting frame of a lighting device according to the present invention has a filter mounted on the front surface and a plurality of heat dissipation holes provided on a cylindrical outer peripheral wall. An annular frame equipped with a plurality of arm pieces having a spring property is inserted into the frame body, and the filter is sandwiched between the annular frame and the front wall of the frame body. The bent piece portion of the arm piece is fitted into a plurality of corresponding heat radiation holes in the frame body.

[0006]

[Action]

 Next, the operation of the filter mounting frame of the lighting equipment according to the present invention will be described. The annular frame is inserted into the frame body, and the filter is sandwiched between the annular frame and the front wall of the frame body. In this state, the arm piece blocks the heat radiation hole to some extent.

[0007]

【Example】

 An embodiment of a filter mounting frame of a lighting device according to the present invention will be specifically described below with reference to the drawings. 1 and 2 show different embodiments of a filter mounting frame of a lighting device according to the present invention, showing a front view of the lighting device with a part cut away, and a front face 3 A plurality of arm pieces 6, 6, 6, having a spring property are installed in a frame body 2 in which a filter 1 is mounted and a plurality of heat dissipation holes 5, 5, 5, 5 are provided in a cylindrical outer peripheral wall 4. An annular frame 8 including 6 is fitted and inserted, the filter 1 is sandwiched between the annular frame 8 and the front surface 3 of the frame body 2, and a plurality of arm pieces 6, 6 of the annular frame 8 are inserted. The bent piece portions 7, 7, 7, 7 of Nos. 6, 6, 6 are fitted into the plurality of heat dissipation holes 5, 5, 5, 5 provided in the frame body 2, respectively.

FIG. 3 shows an exploded perspective view of the frame body 2 and the annular frame 8, and FIG. 4 shows another embodiment in which the arm piece 6 of the annular frame 8 has a shape different from that shown in FIG. The bending piece portions 7, 7, 7, 7 of the plurality of arm pieces 6, 6, 6, 6 of the annular frame 8 are formed in a dogleg shape as shown in FIG. As shown in FIG. 4, it may be formed in a U-shape, so that the free end of each arm piece 6 has a bent portion 11 for fitting to the front edge 10 of the reflecting mirror 9 of the light source 12. It is provided.

Next, the operation state thereof will be described. An annular frame 8 is inserted into the frame body 2, and the filter 1 is sandwiched between the annular frame 8 and the front wall 3 of the frame body 2. Inside the corresponding plurality of heat dissipation holes 5, 5, 5, 5 of the body 2, the bent piece portions 7, 7, 7, 7 of the plurality of arm pieces 6, 6, 6, 6 of the annular frame 8 are arranged. In this state, the arm pieces 6, 6, 6, 6 slightly close the heat radiation holes 5, 5, 5, 5.

[0010]

[Effect of the device]

 Since the filter mounting frame of the lighting device according to the present invention has the above-mentioned structure, the following effects can be obtained. That is, when inserting the annular frame into the frame body, the spread of the plurality of arm pieces of the annular frame is restricted, so use screws or the like when the annular frame is inserted into the frame body. Not only can they be fixed securely, but the frame for attaching the filter does not need to be replaced each time the form of the luminaire is different, and moreover, there are multiple heat radiation holes in the frame. , The bent parts of the multiple arm pieces of the annular frame are fitted together.In this state, even if the arm pieces slightly block the heat radiation holes, they will not be in a completely closed state. The hole can be used effectively, and the light from the light source is prevented from leaking out of the device through the heat dissipation hole.
