Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an improvement in a baffle support structure for a lighting device, and particularly to a structure that can easily and reliably support a baffle on the lower surface of a lighting device.

[Conventional technology and its problems]

Conventionally, in the case of a fluorescent lighting device equipped with a long fluorescent lamp, for example, a reflector 1 and a light source 2 are installed inside to prevent glare, as shown in FIG. A baffle 5'ft supported by a frame 4 is provided on the lower surface of the rectangular lighting device main body 3.

In the same structure, the baffle 5 is attached to the frame 4 in the lighting fixture body 3.
Because it uses a large number of parts, it takes time to assemble,
In addition, since the baffle is supported by the frame, the frame and baffle can easily protrude from the bottom of the lighting fixture.
Furthermore, when replacing the light source 2, there is a drawback that the baffle must be removed for maintenance and inspection of the interior of the lighting fixture body 3.

[Purpose of the invention]

The present invention has been invented in view of the above points, and has a relatively simple structure that allows the baffle to be easily and reliably supported on the illuminator body, and furthermore allows the baffle to be easily opened and closed.
It is an object of the present invention to provide a baffle support structure for a lighting device that allows easy replacement of the light source or maintenance and inspection of the inside of the lighting device body.

[Structure of the invention]

The present invention'Ir: FIGS. 1 to 4 will be explained below. In the figure, reference numeral 11 denotes a box-shaped lighting fixture body, and 12 denotes an open-bottom reflector having an arcuate section, which has an enlarged space 13 at one end and is disposed inside the lighting fixture body 11. It is. 14 is a flat reflecting plate, and the reflector 14
It may be configured integrally with. 15 is a socket provided inside one end of the lighting device body 1; 16 is a long tube-shaped light source attached to the socket 15; for example, a straight tube-shaped fluorescent lamp; 17 is a slanted V-shaped cross section; It is a support plate having a piece 18 and is supported on the inner wall of the lighting fixture main body 11 on the enlarged space side. Further, near the tip of the inclined piece 18 of the support plate 17, a plurality of 20ft notched grooves having a protrusion 19 at the center are arranged at equal intervals. Reference numeral 21 denotes a baffle holding plate having a hook-shaped portion 22, and is supported on the inner wall of the lighting fixture body 11 on the enlarged space side. Further, a plurality of notch grooves 24 having a protruding portion 23 at the center of one inner cavity are formed at the tip of the hook-shaped portion 22 at the same interval. 25 is the support plate 1γ and the baffle holding plate 2
1 to the inner wall of the lighting fixture body 11, 26 a support bolt for clamping and fixing the support plate 17 and the baffle press plate 21, and 27 between the support plate 17 and the baffle press plate 21. It is a baffle having one end clamped and fixed to the support plate 1T, and has a cutout groove 28 corresponding to the inclined piece 18 of the support plate 1T and a hole 29 corresponding to the protrusion 23 of the holding plate 21.

[Baffle assembly]

0) First, the inclined piece 18 of the support plate 17 is fitted into the notch groove 28 of the baffle 27, and the baffle 2γ is engaged with the support plate 1T.

(b) Next, the support plate 17 and the baffle holding plate 21' are connected to the hinge 25 supported on the lighting equipment main body 11, and the support bolt 2
6, the protrusion 19 of the cutout groove 2G of the support plate 17 presses a part of the baffle 27, and the baffle holding plate 2
The protruding portion 23 of the first notched groove 24 presses a portion of the upper end of the baffle 2T, and the baffle is reliably supported at a predetermined location on the lower surface of the lighting fixture body 11.

〔Effect of the invention〕

As described above, the present invention has an inclined piece having a V-shaped cross section on the inner wall of the lighting equipment main body on the enlarged space side, and a plurality of notched grooves having a protrusion in the center are formed near the tip of the inclined piece. A support plate and a baffle press plate having a plurality of notched grooves having a protrusion at the center of the inner cavity are provided at the tip of the hook-shaped portion, and the support plate and the press plate correspond to the inclined piece of the support plate. a notch groove;
Since the buckle is configured to sandwich a large number of baffles having holes corresponding to the cutout grooves of the holding plate, the buckle is easily and reliably supported between the supporting plate and the holding plate, and supports one end of the baffle. The other free end of the baffle is supported on the same plane.

Furthermore, unlike conventional structures, a frame is not used, so the number of parts is small, and the frame does not protrude from the lower surface of the lighting fixture body. Furthermore, with the conventional structure, it was necessary to remove the baffle together with the frame when replacing a light bulb or performing maintenance on the inside of the lighting equipment body, which took time and effort, but with the structure according to the invention, the support bolt is loosened and the baffle is supported. There is an advantage that it is possible to easily replace the light bulb and perform maintenance and inspection work on the inside of the lighting equipment body without opening the panel.
