Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to an improved lighting fixture body that is easily affected by heat generated by lamps and the like.

(Prior art) Conventionally, structural materials such as the main body of lighting equipment are made of lamps,
Considering the cause of heating from the heater part, ballast, etc.
In order to prevent structural materials from deforming, melting, etc., use materials that meet the worst conditions that structural materials can withstand, such as heat-resistant materials when made of synthetic resin.
ABS (acrylonitrile butadiene styrene resin) is selected and processed.

(Problem to be solved by the invention) However, the conditions for selecting the conventional structural materials mentioned above are based on the worst-case conditions that the main body of the lighting equipment, especially the fitting part of the mounting plate and its periphery, will be subjected to. Therefore, it is necessary to use effective materials even in areas where there is no need to consider the effects of heating causes, resulting in high costs, and there are limits to product development in terms of price. The periphery of the mounting plate fitting portion is likely to be damaged when the mounting plate is inserted, making the arrangement of the mounting plate unstable. Therefore, this invention aims to improve the drawbacks of the above-mentioned conventional ones, and it can be easily and reliably avoided even if cheaper materials are used for the lighting equipment body during the work process. It is possible to prevent deformation and melting of the structural material of the lighting equipment body due to uncontrollable heating (100 to 130℃), and also to reinforce the periphery of the recessed part, further reducing product costs and achieving higher quality. The aim is to promote product development.

(Means for solving the problem) Insert-molding or gluing a heat-resistant sheet into the recessed part or its periphery, which is the fitting part of the mounting plate that secures the ballast, lamp, etc., on the main body of the lighting equipment. This is what happens.

(Function) As described above, by insert-molding or gluing a heat-resistant sheet to the recessed part of the lighting fixture body that serves as the fitting part for the mounting plate, or the peripheral part thereof,
In addition to preventing the heat generated from the parts of the lighting fixture from being transmitted to the structural material, by adhering or integrally molding a heat-resistant sheet around the periphery of the recess, this area can be reinforced and the recess can be prevented from missing. It is something.

(Example) This invention will be further explained with reference to an example shown in the drawings. Reference numeral 1 is a lighting fixture, and 2 is a lighting fixture body made of resin, for example, inexpensive styrene. A recessed portion 3 is provided in the center of the lighting fixture body 2, and a mounting plate 6 is provided with a lamp support spring 8 and electrical components such as a ballast 7 for stably supplying voltage to this recessed portion 3. are fitted and fixed, and a fluorescent lamp 10 having a built-in heater part 9 for heating the filament part is attached to the lamp support spring 8. A concave portion 3 is provided in the center of the main body 2 to prevent heat generated from the ballast 7 from being transmitted to the main body 2.
Next, a heat-resistant sheet, for example, a polyethylene terephthalate sheet (about 0.1 mm thick) 5 is integrally molded or adhered to the main body 2 so as to be placed at the location where the ballast 7 is located. Furthermore, lamp 9
The same applies to the peripheral edge 4 of the recessed part 3 provided in the main body 2 in order to prevent the heat generated by the heater part 10 built into the main body 2 from being transmitted to the main body 2 and to prevent the peripheral edge of the recessed part 3 from missing. , thickness 0.1mm
A heat-resistant sheet 5 having a heat-resistant sheet such as polyethylene terephthalate having a certain degree of heat resistance is insert-molded or bonded.

(Effect of the invention) As mentioned above, it is easily affected by the cause of heating.
Heat from the heat source can be blocked by using expensive heat-resistant materials only in the fitting parts of the mounting plates that fix heat sources such as ballasts and lamps, that is, in the recesses and their peripheries. It also prevents thermal deformation and melting of the lighting equipment body, which was a problem in the past, and also
For example, if the entire structure is made of ABS, which is a heat-resistant material, the cost will increase by about 160 yen, but if the entire structure is made of steel, as in this invention, and polyethylene terephthalate is partially used, the cost will increase by about 10 yen. In addition, the heat-resistant sheet strengthens the periphery of the concave part and has an excellent effect of preventing chipping.
