Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a lighting fixture having a cylindrical lighting fixture body and housing electrical components such as a ballast within the lighting fixture body.

[Background technology]

Conventionally, when storing electrical parts such as a ballast in a cylindrical lighting equipment body such as a stand lighting equipment, the first
As shown in the figure and FIG. 2, mounting ribs 2 are provided protruding from the inner surface of the lighting fixture main body 1, which is extruded from aluminum or the like into a substantially semi-cylindrical shape, and the holding plate 3 and the component mounting plate 4 are fixed with screws. 5 and fix it by sandwiching the mounting rib 2, and after installing the stabilizer 6 on the component mounting plate 4, a substantially semi-cylindrical shape is attached to the cover mounting base 7 protruding from the component mounting plate 4. The cover 8 was fixed with mounting screws 9 to form a cylinder, thereby forming an integrated lighting fixture body.

As a result, the main body of the lighting fixture is divided into two parts, resulting in an unsightly appearance, and the installation method becomes complicated, resulting in high costs.

[Purpose of invention]

An object of the present invention is to enable parts such as a ballast to be reliably and easily attached to a cylindrical lighting equipment body without dividing the lighting equipment body.

[Disclosure of invention]

The lighting device according to the present invention has mounting ribs protruding from the inner surface of the cylindrical lighting device body, and a substantially rectangular component mounting plate on which electrical components such as ballasts are attached is fastened to a substantially rectangular holding plate using fixing screws. This is a lighting fixture in which the electrical components are fixed to the lighting fixture body by sandwiching the mounting ribs by bending the retaining plate so that both ends of the retaining plate move away from both ends of the component mounting plate. With the convex surface of the curve facing the component mounting plate, insert the claws protruding from one end of the presser plate into the claw engagement holes formed at one end of the component mounting plate and engage them with each other. is provided with a fixing screw insertion hole, while a female thread is provided near the other end of the holding plate in correspondence with the fixing screw insertion hole, and after inserting the fixing screw into the fixing screw insertion hole, screw it into the female thread to attach the component. The plate and the holding plate are combined, and the fixing screws are arranged on the opening side of the lighting fixture body, and parts can be attached by simply tightening the fixing screws from the opening of the cylindrical lighting fixture main body.

〔Example〕

Embodiments of the present invention will be described below with reference to FIGS. 3 and 4. The lighting fixture body 1 is extruded from aluminum or the like into a substantially cylindrical shape, and has a pair of mounting ribs 2 protruding from the center of the inner surface and at symmetrical positions with respect to a plane containing the central axis of the lighting fixture body 1. are doing. The holding plate 3 is formed of a rectangular sheet metal,
A female thread 10 is formed near one end, and a claw portion 11 whose pupil is narrower than the overall outline is formed at the other end, and a fold line is formed near the side end of the claw portion 11 in a direction substantially perpendicular to the long side. It is formed and bent at a slight angle.
The component mounting plate 4 is formed of a rectangular sheet metal having approximately the same external dimensions as the holding plate 3, and the holding plate 3 is located near one end.
It has a long hole 12, which is a fixing screw insertion hole, at a position corresponding to the female screw 10, and a claw engaging piece 13 having a substantially U-shaped outer shape is continuously provided near the other end at a position corresponding to the claw portion 11. It is bent upward to form a pawl engaging hole 14. A stabilizer 6 is attached to the lower surface of the component mounting plate 4, while a presser plate 3 is attached to the upper surface so that the convex side of the bent portion faces the component mounting plate 4 and both ends are spaced away from the component mounting plate 4. At this time, the holding plate 3 and the component mounting plate 4 are
1 is fitted into the claw engaging hole 13 of the component mounting plate 4, and the fixing screw 5 is inserted through the elongated hole 12 of the component mounting plate 4 and screwed into the female thread 10 of the holding plate 3 to be integrated. Then, insert the mounting rib 2 between the holding plate 3 and the component mounting plate 4 through the opening of the lighting fixture body 1, and set it in a predetermined position.
Fixing screws 5 are tightened through the opening of the lighting fixture body 1, and the mounting rib is clamped and fixed between the holding plate 3 and the component mounting plate 4. At this time, the retaining plate 3 has its bent portion as a fulcrum, the claw portion 11 is held down by the claw engaging piece 13, and the end portion on the side of the female thread 10 is pulled down to be securely fixed.

[Effect of idea]

According to the present invention, parts can be installed simply by tightening the fixing screws from the opening of the cylindrical lighting device body, and the lighting device body is cylindrical and does not need to be divided, so that the installation can be performed reliably and easily.

Claims (1)

[Scope of utility model registration request] A mounting rib is provided protruding from the inner surface of the cylindrical lighting device body, and a substantially rectangular component mounting plate on which an electrical component such as a ballast is attached is fastened with a fixing screw to a substantially rectangular holding plate to secure the mounting rib. In a lighting fixture in which electrical components are clamped and fixed to the lighting fixture body, the holding plate is bent and the bent convex surface of the holding plate is attached to the component mounting plate so that both ends of the holding plate are moved away from both ends of the component mounting plate. The claws protruding from one end of the holding plate are inserted into the claw engagement holes formed at one end of the component mounting plate so that they engage with each other, and the fixing screw insertion holes are provided near the other end of the component mounting plate. On the other hand, near the other end of the holding plate, a female thread is provided corresponding to the fixing screw insertion hole, and after inserting the fixing screw into the fixing screw insertion hole, the fixing screw is screwed into the female thread to connect the component mounting plate and the holding plate. A lighting device characterized in that the fixing screw is arranged on the opening side of the lighting device main body.
