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 fluorescent lamp lighting fixtures equipped with elongated fluorescent lamps, for example, in order to prevent glare, a reflector 1 and a light source 2 are mounted inside as shown in Fig. 5. A baffle 5 supported by a frame 4 is provided on the lower surface of the instrument body 3.

In the same structure, the Batsuful 5 is attached to the frame 4 in the lighting equipment body 3.
Because it uses a large number of parts, it takes time to assemble,
In addition, since the baffle is elegantly supported, the frame and baffle do not protrude or form a tight structure on the underside of the lighting fixture.
Furthermore, when the light source 2 is completely replaced, there are drawbacks such as the need to remove the baffle when performing maintenance and inspection inside the lighting fixture body 30.

[Purpose of the invention]

The present invention was 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 lighting equipment body, and further 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 will be explained below with reference to FIGS. 1 to 4. In the figure, 11 is a box-shaped lighting fixture body, and 12 is a reflector with an opening at the bottom of the lighting fixture body 11, and is configured in an arc shape. 13Vs.

A flat reflector, L5 is a socket provided inside one end of the lighting device main body 11, 15 is a long tube light source attached to the socket 14, and is a straight tube fluorescent lamp, 15 is a cross section V. It is a support plate having a letter-shaped inclined piece 16, and is fixed inside one end of the lighting fixture body 11. 1T is a baffle that has a notch @ia1 into which the inclined piece 16 of the support plate 15 fits, and the upper surface of the free end of the other end is the reflector 12.
It is configured to correspond to the inner shape of the. hook-shaped part 20 at 19
The baffle holding plate has a hook-shaped portion 20 to press the upper surface of the outer end of the baffle 1T, and one end of the baffle is connected to the outer end of the support plate 15 with a hinge 21.

Numeral 22 is a bolt for tightening the support plate 15 and the baffle pressing plate 19.

[Baffle assembly]

@) First, the inclined piece 16 of the support plate 15 is fitted into the notch groove 18 of the baffle 1T, and the baffle 17 is engaged with the support plate 15.

(b) Next, the support plate 15 and the baffle presser plate 19 are connected to the hinge 21 supported on the lighting device main body 11, and tightened with bolts 22.

〔Effect of the invention〕

As described above, the present invention fixes a support plate having an inclined piece with a V-shaped cross section to one end of the interior of a lighting fixture body that supports a reflector and a light source, and provides a notch into which the inclined piece of the support plate is fitted. Since the baffle having the groove is fully supported and the upper surface of the outer end of the baffle is pressed by the hook-shaped part of the baffle holding plate, the baffle can be assembled easily and reliably as described above. Since no frame is used, the frame does not protrude from the bottom of the lighting fixture body as in conventional structures, and in addition, with conventional structures, the baffle cannot be used as a frame when replacing light bulbs or performing maintenance inspections inside the lighting fixture body. However, with the structure of the present invention, by loosening the bolts and opening the support plate that fully supports the baffle, it is possible to replace the light bulb and perform maintenance and inspection inside the lighting fixture body. It has the advantage of being easy to implement.
