Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a lighting device.

[0002]

[Prior Art]

 Attach the metal main body 1 with a gutter-shaped cross section with both ends fixed by end covers and the fixture components such as the lamp and the lighting device to one surface, and fit into the opening of the main body 1. In the luminaire as shown in FIG. 6 which is composed of the plate 2, the mounting springs 3 which are attached to the upper surface of the conventional mounting plate 2 and whose both ends are projected from the both side edges of the mounting plate 2 are used. It was attached.

That is, the mounting projections 4 inclined downward are provided on the inner surfaces of both side walls of the main body 1, and both side ends of the one-side mounting spring 3 are bent in a substantially V-shaped cross section, and attached to the opening of the main body 1. When the plate 2 is fitted, the elasticity of the mounting spring 3 is used to elastically engage the bent portion 3a of the mounting spring 3 with the mounting projection 4 as shown in FIG. It was fixed to the body 1.

[0004]

[Problems to be solved by the device]

 However, in the above-mentioned conventional example, since the spring deformation of the mounting spring 3 is used, there is a problem that the shape of the mounting spring 3 becomes large when the mounting strength is optimized. Further, it is necessary to prevent the main body 1 from hitting within the deformation range of the mounting spring 3, and therefore it is necessary to take a large dimension A in FIG. 7, and the dimension B of the portion where the mounting projection 4 is provided. Since the mounting spring 3 does not bend unless a certain value is taken, it is necessary to increase the sectional shape of the main body 1 as a result.

The present invention has been made in view of the above problems, and an object thereof is to make a mounting portion on the body side small and to make a main body thin. To provide.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention provides a window portion for emitting lamp light at the bottom of a metal main body of a gutter having a substantially U-shaped cross section with both ends fixed by end covers. The projections for mounting are inclined and projected from the inner edge of the opening of the main body corresponding to the range of the longitudinal direction of the main body toward the bottom of the main body, and fixture components such as lamps and lighting devices are attached and fitted into the opening of the main body. The mounting plate is provided with mounting brackets with the tips protruding outward from both side edges of the mounting plate in the direction of the main body, and the tip of the mounting protrusion is attached to the inclined surface of the front part of the mounting bracket by the elasticity of the side wall of the main body. The mounting plate is fixed to the main body by abutting engagement.

[0007]

[Action]

 Thus, according to the present invention, when the mounting plate is fitted into the opening of the main body, the tip of the mounting metal fitting on the mounting plate side pushes the inclined surface of the mounting projection on the main body side to open the window hole of the main body. Since the side wall on the main body side easily bends within the longitudinal range of the part due to the existence of the window hole, both side walls of the main body elastically deform outward and the tip of the mounting bracket is attached to the main body side. The mounting projection on the main body side is elastically locked to the inclined surface of the tip of the mounting bracket beyond the above, and the mounting plate is fixed to the main body.

[0008]

【Example】

 Hereinafter, the present invention will be described with reference to examples. The main body 1 of the luminaire of the present invention is made of metal, which is formed in a trough shape having a substantially U-shaped cross section as shown in FIG. It is fitted and fixed to. Further, a window portion 6 for emitting light of the straight tube type fluorescent lamp L is provided in the bottom portion.

As shown in FIG. 3, mounting protrusions 4 are provided integrally on both inner edges of the upper surface opening of the main body 1 located within the longitudinal direction of the window hole 6 so as to project downward in a diagonal direction. There is. Two protrusions 4 are provided on each side as shown by the arrow in FIG. On the other hand, a lighting device 7 such as an inverter, a socket 8 for mounting the fluorescent lamp L, a terminal block 9 and other equipment components are installed on the lower surface of the mounting plate 2, and the upper surface corresponds to the above-mentioned mounting projection 4. Two mounting brackets 10 are provided. The tip ends of both ends of each mounting member 10 project outward from both side edges of the mounting plate 2, and the tip portions thereof are bent downward in a substantially V shape.

In order to fit the mounting plate 2 into the opening of the main body 1, first, the mounting plate 2 is pushed into the opening of the upper surface of the main body 1 with the mounting side of the device component facing downward. Then, when the mounting plate 2 is further pushed in with the lower inclined surfaces of the bent portions 10a at both ends of the mounting bracket 10 contacting the inclined surfaces of the mounting protrusions 4, the main body at the position where the mounting protrusions 4 are provided. Since the bottom of the side wall of No. 1 is easily bent by the window hole section 6, the side walls of both sides expand outward by the above-mentioned pushing, and the bent portions 10a at both ends of the mounting metal fitting 10 get over the tip of the mounting projection 4. It will be. Due to this overcoming, both side walls of the main body 1 that have expanded outwardly try to return inward due to their elasticity, and the tips of the attachment projections 4 are brought into contact with the upper inclined surfaces of the bent portions 10a at both ends of the attachment fitting 10. Make elastic contact. As a result, the mounting plate 2 is fixed to the main body 1 as shown in FIG. 5 (a) and 5 (b) are a top view and a cross-sectional view, respectively, in a state in which the attachment plate 2 is attached to the main body 1.

[0011]

[Effect of the device]

 The present invention is provided with a window hole for emitting lamp light at the bottom of a metal body with a substantially U-shaped cross section whose both ends are fixed by end covers, and corresponds to the longitudinal range of this window hole. From the inner edge of the opening of the main body, incline the mounting projection toward the bottom of the main body, attach the fixture components such as the lamp and lighting device, and insert the mounting plate that fits into the opening of the main body from both edges. The mounting plate is provided with a mounting portion projecting outwardly and obliquely toward the main body, and the tip of the mounting projection is abutted and engaged with the inclined surface of the front end of the mounting bracket by the elasticity of the side wall of the main body. Since the mounting plate is fixed to the main body, the mounting plate can be fixed using the elasticity of the main body without using a spring-made mounting member as in the conventional case. Providing a mounting protrusion like Or by increasing the site, or it is not necessary to increase the cross-sectional area of the body for the deflection of the spring, resulting body is effective cormorants have becomes possible to manufacture a thin and.
