Description

[Detailed description of the invention] [Industrial application field] The present invention relates to the improvement of support structures for lighting equipment, and is particularly applicable to areas where clean air is required, such as computer installation locations, semiconductor factories, and hospital operating rooms. Related to support structures for lighting equipment used in clean rooms.

[Conventional technology and its problems]

Conventionally, various designs have been made for lighting equipment used in computer installation locations, semiconductor factories, hospital operating rooms, etc. to purify the indoor air. There are few.

For example, as shown in Fig. 1, a conventional support structure for lighting equipment includes attaching a lighting equipment main body 2 such as a fluorescent lamp to a support bolt 1 installed on the back side of the ceiling of a building, and attaching a reinforcing plate 3. It is fixed with nut 4.

However, according to the same structure, air flows into the lighting fixture main body 2 through the threaded portions of the support bolt 1 and the nut 4. Therefore, if the airtightness of the lighting fixture body 2 and the glove supported on the lighting fixture body 2 is insufficient, or if the glove is opened for maintenance inspection inside the lighting fixture body 2, clean air is required. There is a drawback that the air in computer installation rooms, semiconductor factories, or hospital operating rooms is contaminated with dust.

[Purpose of invention]

The present invention was devised in view of the above points, and it does not allow outside air to flow into the interior of the lighting equipment, making it possible to purify the air in the room where the computer is installed. It is an object of the present invention to provide a support structure for a lighting fixture that can increase its strength.

[Structure of the idea]

The present invention will be explained below with reference to FIGS. 2 and 3. In the figure, reference numeral 11 denotes a lighting fixture body constituted by a plate; 12 denotes a reinforcing plate supported on the inner wall of the support portion of the lighting fixture body 11; The section has a rising portion 13 having a truncated conical cross section. Reference numeral 14 is a packing having a hole 15 in the center, the outer shape is configured to be the same as the inner cavity of the rising portion 13, and the size is such that a part of the outer end slightly protrudes from the outer end opening of the rising portion 13. It is structured as follows. Reference numeral 16 denotes a support bolt supported, for example, in the attic of a building, and passes through the hole 15 of the packing 14. 1
A washer 7 is attached to the support bolt 16 and comes into contact with the lower end of the packing 14, and its diameter is larger than the lower end of the packing 14. A nut 18 is screwed onto the support bolt 16 and presses the packing 14 through the washer 17. Reference numeral 19 designates lamp mounting sockets provided on both sides of the interior of the lighting fixture body 11.

Next, the support of the lighting equipment in the lighting equipment support structure described above will be explained. For example, a lighting fixture main body 11 consisting of a reinforcing plate 12 fixed to a support bolt 16 provided in the ceiling of a building is fitted, and a packing 14, a washer 17, and a nut 18 are attached to the support bolt 16.
are fitted in sequence. In this case, the upper end of the lighting fixture is held down, for example, with a nut screwed into the support bolt 16.

[Effect of idea]

As described above, the present invention supports a reinforcing plate having a rising portion having a truncated conical cross section on the inner wall of the support portion of the plate-shaped lighting equipment main body, and facing the inner wall of the lighting equipment main body. Inside the rising part of the reinforcing plate, a packing is installed which has the same shape as the inner cavity of the rising part, a part of which slightly protrudes from the outer end opening of the rising part, and has a hole in the center. The support bolt is supported by passing through the support bolt, the washer is brought into contact with the outer periphery of the support bolt, and the washer is pressed against the support bolt by screwing the nut onto the support bolt. When the nut is screwed together through the reinforcing plate and the supporting bolt, the packing comes into close contact with the reinforcing plate and the supporting bolt.

When the packing comes close to the reinforcing plate and support bolt,
Dust from the ceiling of the building does not enter the inside of the lighting fixture body and the globe supported by the lighting fixture body through the threaded portion of the support bolt and nut.

Since dust does not enter the inside of the lighting equipment, even if you open the glove to replace the lamp or perform maintenance and inspection of the lighting equipment, dust will not enter rooms that require clean air, making it ideal for computer installation rooms or hospitals. It is ideal as a support structure for lighting equipment installed and used in operating rooms, semiconductor factories, etc.

Further, since a reinforcing plate having a truncated cone-shaped rising portion is provided on the lower surface of the lighting fixture body, the strength of the reinforcing plate is increased, and there is an advantage that the lighting fixture body can be reliably supported by the support bolt.
