Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to lighting devices for indoor plazas, gymnasiums, etc., and provides a lighting device that prevents damage to the light fixtures by balls, etc., allows the light fixtures to be moved freely, and is inexpensive to construct. The purpose is to

Traditionally, Figure 1a was used for lighting in indoor plazas, gymnasiums, etc.
As shown in the figure, a fixture 2 is used in which the opening of the shade 3 is covered with a wire mesh 4, and a ball etc. is held in the lamp 1 by the wire mesh 4.
It prevents you from hitting. However, such a device has disadvantages in that if the shade 3 is made of aluminum or the like, the shade will be deformed if the ball hits it, and the hanger 5 will break from the base due to the impact. In order to eliminate such obstacles, when the light fixture 2 is recessed into the ceiling surface 6 as shown in Figure b, the ceiling becomes a double structure, which increases construction costs, and there are other problems such as the inability to move the light fixture. There's a problem.

The present invention provides a novel lighting device that eliminates the above-mentioned drawbacks by mounting a plurality of light fixtures downward on a wire mesh with a frame on the periphery in a removable manner and suspending the entire device from the ceiling. be.

FIG. 2 is a side sectional view of one embodiment of the present invention, and FIG. 3 is a bottom view thereof. In these figures, 7 is a wire mesh with a frame 8 on its periphery, which is suspended from the ceiling by a hanging rod 9 attached to the frame 8 at one end, and a lamp 1 is mounted on the top surface of the wire mesh 7. A plurality of lamps 2 each having a built-in lamp are removably attached to the shade 3 by means of a fixture 10 with the opening facing downward. As an example of the fixture 10 is shown in FIG. 4, a flange or protruding metal fitting 11 is provided on the side surface of the shade 3 of the lamp 2, and a bolt 13 having a hook-shaped hook portion 12 at the tip is attached to the lower side of the wire mesh 7. and attach the bolt 13 to the flange or protruding metal fitting 11 with the wing nut 14.
It is configured such that the lamp 2 is attached to the wire mesh 7 by tightening the wire. Since removing the lamps can be easily done by loosening the wing nut 14, it is also easy to move the plurality of lamps 2, which have been installed at the position shown by the solid line in FIG. 3, to the position shown by the broken line in the same figure. Also, it is easy to increase or decrease the number of lamps.

Use a small mesh for the wire mesh 7 to prevent the ball from hitting the lamp. However, if the mesh is fine, the ball that rises from the side may ride on the wire mesh and not fall down, so measures such as making the mesh near the shade finer and making the periphery rougher can be considered. In addition, in order to prevent the balls from getting caught on the wire mesh, wire meshes 15 and 16 are provided with a distance A larger than the diameter of the balls, as shown in FIG.
are arranged in two stages, upper and lower, the lamp 2 is attached to the upper wire mesh 15, the lower wire mesh 16 is shifted by 1/2A, which is smaller than the diameter of the ball, and the upper and lower wire mesh 15,
By making the interval 16 larger than the diameter of the balls, the balls can be made to fall downward from the wire mesh instead of staying on the wire mesh.

Figure 6 shows a motor 1 fixed to the ceiling by hanging a wire mesh 7 with a plurality of lamps 2 attached thereto by wires 17.
8. In another embodiment of the present invention in which the lamp 2 is raised and lowered by the winding drum 19, the lamp 2 can be increased or decreased, cleaned,
This makes maintenance work such as removing balls on the wire mesh easier.

As described above, the present invention suspends a wire mesh with a frame around its periphery from the ceiling surface, and attaches and detaches a plurality of light fixtures onto the wire mesh with their light irradiation direction facing downward. Install a guard on the light fixture,
Compared to conventional lighting systems in which these lights are individually hung from the ceiling, construction costs are reduced because multiple lights can be hung from a common hanging fixture.

2 There is no need to install wire mesh on each individual light fixture, so
The structure of the lamp becomes simple and can be manufactured at low cost.

3. Not only the lamp as the light source but also the lamp itself is protected by a wire mesh, so there is no risk of the lamp being damaged by a ball or the like hitting it.

4. It is easy to increase or decrease the number of lamps or change the arrangement of multiple lamps.

5. In addition to the above, if the lamp is a discharge lamp and requires a ballast, the ballast can be mounted on a wire mesh to improve heat dissipation and make it more compact.

Effects such as this can be obtained.
