Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a lighting fixture, and relates to a fixing structure between a decorative frame and the main body of a fixture, such as a downlight, which is embedded and fixed in a ceiling surface.

[Conventional technology]

As shown in FIG. 4, this type of conventional downlight type lighting fixture has an annular decorative frame 3 attached by screws or screws to the lower ends of both side legs 2 of a substantially U-shaped main body 1 which is embedded and fixed in the ceiling surface. A structure was adopted in which it was fixed with rivets 4.

[Problem that the invention attempts to solve]

In the conventional lighting equipment described above, the decorative frame 3 is attached to the main body 1 in advance and integrated, and the main body 1 is embedded and fixed in the ceiling surface in this state, so the decorative frame 3 cannot be stably attached to the main body 1. Due to this problem of stability, the decorative frame 3 is fixed with two screws or rivets 4 even though the legs 2 on each side do not require reinforcement. Therefore, four screws or rivets 4 are required to attach the decorative frame 3 to the main body 1, which requires a large number of man-hours to prepare screw insertion holes and tapped holes in each leg 2 of the main body 1 and the decorative frame 3, respectively. Even with riveting, there were many caulking points, which caused the problem of being expensive.

Furthermore, as described in Japanese Utility Model Publication No. 55-48499, in a lighting fixture having a structure in which a decorative frame is fixed to both legs of a substantially U-shaped main body, a decorative frame is attached to the outside near the bottom of both legs of the main body. A structure is known in which the upper end of the decorative frame is engaged with the bulging bent edge.

In the structure described in this Utility Model Publication No. 55-48499,
Although it is possible to position the main body and the decorative frame in the vertical direction, it is not possible to position the decorative frame in the circumferential direction.If the positions of the legs on both sides of the main body and the decorative frame are misaligned, the main body and the decorative frame will not be assembled. This may cause distortion and make it impossible to fit into the embedded hole in the ceiling surface, etc.
In addition, since the upper end of the decorative frame is only engaged with the bent edges formed on both legs of the main body, the mounting strength is low, and the mounting board that is screwed to the decorative ring is located at the upper edge of the decorative ring. Since it is formed into a substantially U-shape with reinforced edges provided on both sides, it is easy to bend and twist from the part located at the upper edge of the decorative ring at the bottom of the part where the reinforced edges are formed. This is a problem that occurs easily and the main body lacks rigidity.

The present invention was developed in view of the above-mentioned problems, and the main body and the decorative frame are reliably positioned, and the main body and the decorative frame are stabilized by reducing the number of places where the main body and the decorative frame are fixed using fixing devices such as screws or rivets. The object of the present invention is to provide a lighting fixture that is fixed in place, requires fewer processing steps, increases the rigidity of the main body, and can be obtained at low cost.

[Means for solving problems]

The lighting fixture of the present invention includes a substantially U-shaped main body that is embedded and fixed in the ceiling surface and has mounting legs on both sides, an annular decorative frame that is attached to the legs on both sides of the main body, and a decorative frame that is attached to the main body. a lamp socket, and a reflector mounted inside the main body to surround the lamp attached to the lamp socket; bent reinforcing edges are also formed on both sides of both side legs of the main body; A notch is formed at the lower part of each reinforcing edge, and the lower end notched edges of the reinforcing edges on both sides are engaged with engagement grooves formed on the upper edge of the decorative frame, and both legs of the main body are fitted on the outer surface of the decorative frame. The inner surfaces of the lower ends of the two are in contact with each other and fixed with fixing devices such as screws or rivets.

[Effect]

In the lighting fixture of the present invention, the lower parts of the reinforcing edges on both sides are bent and formed on both sides of the main body, and the lower end notches of the reinforcing edges on both sides are formed on the upper edge of the decorative frame. By engaging with the engagement grooves, the main body is prevented from moving in both directions of the decorative frame. One fixing tool for each leg is enough to securely fix the main body and the decorative frame.
