Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to improvements in lighting equipment, and particularly to a mounting structure for a louver provided on the front surface of a lighting equipment to prevent glare.

[Conventional technology and its problems]

Conventionally, lighting equipment used for sports lighting such as ball games, plaza lighting at ports and airports, etc. has a light source 2 inside a paraboloid-shaped lighting equipment body 1 to prevent glare, for example, as shown in FIG. At the same time, a front glass 3 is supported on the front surface of the lighting equipment main body 1, and a band-shaped support 5 is supported on the flange 4 integrally formed in the front end opening of the lighting equipment main body 1. The end portion of the louver 6 is supported on the front side of the front glass 3, and the louver 6 is supported on the front side of the front glass 3.

By the way, according to the same structure, in order to support the louver 6 at the front end of the lighting device main body 1, the band-shaped support 5 is used.
Since it is supported by tightening with screws, there are many parts and it takes time to assemble. Furthermore, louver 6
Since the louvers are provided on the outer surface of the front glass 3, wind pressure increases, and rainwater splashes on the louvers, making them susceptible to corrosion.

Therefore, as another conventional structure, a louver is supported on the inner surface of a front glass supported at the front end of a lighting fixture body, thereby eliminating wind pressure on the louver and preventing corrosion of the louver due to rainwater.

However, a hole is provided in the wall that serves as both the reflector and the main body of the louver, and the louver support arm is attached to the hole with screws or rivets, so the hole needs to be made waterproof, which makes the structure It has the disadvantage that it is complicated and takes time to assemble.

[Purpose of invention]

The present invention has been devised in view of the above-mentioned points, and an object of the present invention is to provide a lighting fixture with a small number of parts, a simple structure, and an easy assembly operation.

[Means for solving problems]

The present invention will be explained below with reference to FIGS. 1 to 4. In the figure, reference numeral 11 denotes a lighting fixture main body that also serves as a reflector, 12 a socket supported inside the lighting fixture main body 11, 13 a light source supported in the socket 12, such as a high-pressure mercury lamp, and 14 a lighting fixture main body 11. A front glass is mechanically caulked and supported by the winding portion of the front surface of the front glass, and 15 is a louver supported on the inside of the front glass 14 together with the front glass 14, and is provided on the outer periphery of the louver 15. The end of the support arm 16 is brought into contact with the inside of the front glass 14 and is mechanically caulked together with the front glass 14. 17 is a heat-resistant gasket sandwiched between the outer periphery of the front glass 14 and the winding portion of the lighting device body 11.

Reference numeral 18 denotes an opening/closing lid provided on the side surface of the lighting device main body 11, and is configured so that the light source can be replaced.

Next, the assembly order of the lighting equipment will be explained.

(1) First, a stepped portion is formed in the front opening of the lighting device main body 11, which also serves as a reflector, by press working.

(2) Next, insert the socket 12 inside the lighting fixture body 11.
Further, the support arm 16 of the louver 15 is placed on the stepped portion of the lighting device main body 11, and furthermore, the front glass 14 with a packing 17 attached to the outer periphery is placed on the louver 15.

(3) After this, the upright portion around the front end of the lighting fixture body 11 is pressed and bent, and the louver 15 and the front glass 14 are caulked and supported on the lighting fixture body 11.

[Effect of idea]

As described above, the present invention has the support arm end of the louver caulked and supported on the inside of the front glass together with the front glass at the winding part of the front opening of the lighting equipment body, and the louver is supported on the support arm. Because of this structure, compared to the conventional structure, there are fewer parts, the structure is simpler, and the assembly work can be easily performed.
