Description

[Detailed explanation of the idea] Industrial applications The present invention relates to a structure for mounting a reflector on a lighting device.

Prior Art A lamp is provided at the bottom of one side of a box-shaped main body with an opening at the bottom, the lower side of the lamp is shielded from light by a light-shielding plate, and the lamp is provided diagonally from the top of the lamp to the bottom of the opposite side of the main body. Conventionally, in lighting equipment with a reflector plate, the end above the lamp of the reflector plate is tightened directly upward with a screw, and the end opposite to the lamp is locked in a locking part provided on the main body. (Figs. 5 and 6), or a method of inserting a part of the reflector into a hole provided in the main body (Fig. 7).

Problems that the invention aims to solve However, with the conventional method of locking, locking is not reliable, and when the other end of the reflector is tightened upward, the tip of the reflector may slip up at the locking end. The position of the locking end of the reflector may become uncertain, the mounting angle of the reflector may not be consistent, the curved shape of the reflector may not be as designed, and the desired light distribution may not be obtained. Ta. In addition, the metal fittings of the locking portion are too conspicuous, which is not desirable in terms of appearance.

Furthermore, with the insertion method, the insertion part is weak in strength and becomes difficult to insert even if deformed.
Work efficiency was decreasing.

The object of the present invention is to provide a structure for mounting a reflector on a lighting device that eliminates such drawbacks.

Means for Solving the Problems To this end, in the present invention, a folded part is provided at the tip of a reflection plate that has been formed into a predetermined shape, and a metal fitting having a folded part that fits with the folded part is attached to the main body. The angle of the folded part of the main body is the same as the angle of inclination near the tip of the reflector, and the direction of tightening is the same as the angle of inclination near the tip of the reflector. In this way, the reflector can be installed smoothly and reliably while maintaining the predetermined curve.

Hereinafter, the present invention will be explained in more detail with reference to the drawings showing the embodiments.

Embodiment In a box-shaped main body 1 with an open bottom, a reflector 2 having a predetermined shape is disposed, a lamp 3 is disposed below the reflector 2, and a light shielding plate 4 is disposed below the reflector 2. The lamp 3 is arranged along one longitudinal wall within the body, and the reflector plate 2 extends downward from above the lamp towards the edge opposite the lamp (FIG. 2). There is a folded part 5 bent outward at the tip of the reflector plate, and a metal fitting 6 having a folded part that fits into the folded part is attached to the main body. The angle of the folded portion of the metal fitting 6 is exactly the same as the angle θ near the tip of the reflector.

The reflector 2 gradually curves from the slope near the tip to become horizontal, and continues to the slope part 7 which is sloped in the opposite direction again, and the side part 8 which extends further downward. The reflector is fixed to a reflector mounting bracket 10 fixed to the main body by screws 9 at the inclined portion 7 above the lamp. The inclined portion 7 is perpendicular to the inclined axis near the tip of the reflector.

The side portion 8 does not extend directly below the inclined portion, but extends slightly outwardly from the inclined portion.

To attach the reflector 2 to the main body 1, as shown in Figures 3 and 4, first place the lower end of the side part 8 on the top of the socket 11 where the lamp is attached, temporarily hold it, and then press the folded part of the reflector. 5 to the main body metal fittings 6
After fitting with the folded part, tighten with screw 9. Since the inclined portion 7 is perpendicular to the axis of inclination near the tip of the reflector, the tightening direction of the reflector is the same as the axis of inclination near the tip of the reflector, and the reflector is It can be installed smoothly and securely while maintaining the pre-defined curve.

Furthermore, since the side portions 8 are slightly inclined outward, they come into contact with the reflector mounting fittings 10 and act as a spring, increasing the tightening effect.

The folded portion 5 and the metal fittings 6 at the tip of the reflector may be provided along the entire longitudinal direction of the edges of the reflector and the main body, respectively, or may be provided at some places.

By adjusting the vertical mounting position of the metal fitting 6 and the folded length of both folded parts, the lower end of the tip of the folded part 5 of the reflector can be aligned with the main body 1.
It can be made so that it is flush with the edge of the main body and there is no gap between it and the main body.

Effects of the invention In this invention, a folded part is provided at the tip of the reflector,
A metal fitting having a folded part that fits with the folded part is attached to the main body, and the angle of the folded part of the main body is the same as the angle of inclination near the tip of the reflector, and the tightening direction is set to the angle of inclination near the tip of the reflector. Since it was set in the same direction as the one above, the locking end may be misaligned, making the position of the locking end of the reflector uncertain, and the installation angle of the reflector may not be consistent, resulting in the curved shape of the reflector not being as designed. Therefore, the reflector plate can be installed smoothly and reliably while maintaining the predetermined curve.

Further, the folded portion is not visible from the outside, which is favorable in terms of appearance.

As described above, the reflector mounting structure of the present invention is extremely superior to conventional structures.
