Description

[Detailed explanation of the idea] [Industrial application field] The present invention relates to lighting equipment.

[Prior Art] Conventionally, a light projection cover that is attached to the bottom opening of a cylindrical lighting fixture body is generally
The lighting fixture body and the mounting frame of the light projection cover are connected with a hanging cord to prevent it from falling during removal, and when installed, the mounting frame of the light projection cover is brought into contact with the bottom opening edge of the lighting fixture body and the mounting frame is attached. The screw hole in the frame was aligned with the screw hole provided at the edge of the opening on the lower surface, and the mounting frame was mounted from the outside surface using screws.

[Problems to be solved by the invention] However, in the conventional example described above, when the mounting frame is attached, the hanging cord is caught between the mounting frame and the lower opening edge of the lighting equipment body. In addition, when installing using screws, it is difficult to align the screw holes in the mounting frame with the screw holes provided on the bottom opening edge of the lighting equipment body.
There was a problem that it took time to install.

The present invention is an attempt to solve the above-mentioned problems, and its purpose is to provide a lighting fixture in which a light projection cover can be easily attached without much effort.

[Means for Solving the Problems] In order to achieve the above object, the lighting fixture A of the present invention has a light projection cover 2 disposed in the lower opening of the lighting fixture main body 1 formed in a cylindrical shape, and cover 2
A projecting piece 3a protruding upward from the mounting frame 3 is inserted into the through hole 4 of the mounting piece 8 provided in the opening on the lower surface, and a hanging string 5 for preventing the light projection cover from falling off is placed inside the lighting fixture body 1. One end is connected to the tip of the projecting piece 3a protruding from the through hole 4, and the other end is connected to the lighting fixture main body 1 located above the upper surface of the mounting piece 8, and the mounting frame 3
A screw 6 inserted from the bottom surface of the holder is screwed onto a mounting piece 8.

[Function] The light projection cover 2 is attached to the lower opening of the lighting fixture body 1 by inserting the projecting piece 3a of the mounting frame 3 into the through hole 4 of the mounting piece 8 provided in the lower opening of the lighting fixture body 1. By inserting the protruding piece 3a into the through hole 4 in this way, the hanging cord 5 is passed through the through hole 4 together with the protruding piece 3a, and the hanging cord 5 is inserted into the lower opening edge of the lighting fixture body 1. In addition, by inserting the projecting piece 3a into the through hole 4, the mounting position of the mounting frame 3 is regulated, and the mounting frame 3 can be fixed with the screws 6. Lighting equipment body 1
When mounting to the lower opening of the holder, the mounting position can be easily aligned using the screw tool 6.

[Example] Figure 1 shows an example of the present invention.
In the illustrated embodiment, a lighting fixture A is shown in which a disc-shaped light projection cover 2 is removably attached to a lower opening of a lighting fixture main body 1 formed in a cylindrical shape. A lamp (not shown) is installed inside the lighting fixture main body 1, and this lamp is covered with a reflecting plate 7 so as to be open at the bottom. A mounting piece 8 is provided along the periphery of the lower opening of the lighting fixture main body 1, and a through hole 4 is provided in this mounting piece 8.
Reference numeral 9 denotes a screw hole into which the screw 6 is screwed in when the light projection cover 2 is attached. The light projection cover 2 is supported by a mounting frame 3 provided on the outer periphery, and the mounting frame 3 has a mounting piece 8 attached to the lower opening edge of the lighting device main body 1.
A projecting piece 3a is provided protrudingly to be inserted into a through hole 4 provided in the. Reference numeral 5 designates a hanging cord for preventing the light emitting cover 2 from falling when the light emitting cover 2 is installed or removed. It is fixed to the upper end of the protruding piece 3a.

Therefore, when attaching the light projection cover 2, the projecting piece 3a provided on the attachment frame 3 is inserted into the through hole 4, and as shown in FIG. The light emitting cover 2 is attached together with the mounting frame 3 by screwing the screw 6 into the screw hole 9 provided in the mounting piece 8 through the screw hole 10 provided in the mounting frame 3. At this time, with the projection piece 3a inserted into the through hole 4, the screw hole 9 provided in the mounting piece 8 and the mounting frame 3
The screw holes 10 provided in the holes 10 are arranged so that their positions match, and the protrusions 3a are inserted into the through holes 4 to attach the mounting frame 3.
By mounting, the mounting frame 3 is positioned, and the screw hole 9 provided in the mounting piece 8 and the screw hole 10 provided in the mounting frame 3 are also aligned. It is designed so that fixing with the tool 6 can be easily performed, and the installation of the mounting frame 3 can be easily done by inserting the protrusion 3a into the through hole 4 without taking much time. . Furthermore, since the hanging cord 5 is connected to the upper end of the protruding piece 3a through the through hole 4, the protruding piece 3a can be inserted into the through hole 4, and as shown in FIG. At the same time, it passes through the through hole 4, and when the mounting frame 3 is installed, it is stored in the lighting equipment main body 1 without being caught between the mounting frame 3 and the lower opening edge of the lighting equipment main body 1. It's like this.

In the illustrated embodiment, the lighting fixture main body 1
Although a cylindrical case is shown, the shape is not limited and may be formed into a rectangular tube shape or the like.

[Effects of the invention] As described above, the invention provides a through hole into which a protruding piece protruding from the mounting frame of the light projection cover is inserted into the mounting piece provided in the lower opening of the cylindrical lighting device main body. Since the protrusion is inserted into the through hole when installing the mounting frame, the mounting position of the mounting frame is regulated, and the mounting frame is attached to the bottom opening of the lighting equipment body using screws. In some cases, the mounting position can be easily aligned using screws.
The light projection cover can be easily attached without taking much time. In addition, since the hanging cord is connected to the protruding piece through the through hole, the hanging cord will be passed through the through hole together with the protruding piece during installation, and there will be a gap between the mounting frame and the bottom opening edge of the lighting fixture body. It is housed within the lighting fixture body without being sandwiched between the two.
