Description

[Detailed description of the invention] The purpose of this invention is to prevent the temperature of the ballast from rising while sealing each lamp to prevent insects in lighting equipment such as Japanese-style jump rear lights that have multiple lamps. It is something.

As shown in Fig. 1, a reflector plate 2 is attached to an appliance body 1 that houses a ballast and other circuit parts, and a plurality of lamps and a globe 3 that covers these lamps are attached to this, making it a Japanese-style jump rear lighting system. If the appliance is sealed to prevent insects, the temperature rise in the ballast becomes a problem.

The present invention solves this problem and provides a glove structure that prevents the temperature of the ballast from rising while keeping the instrument sealed.

Figures 2 to 4 show one embodiment of the present invention, Figure 2 is a perspective view a of the globe of the present invention, an enlarged view of its main parts is a back view c1, Figure 3 is a bottom view of the entire lighting fixture. FIG. 4 is a side sectional view thereof.

In these figures, reference numeral 1 denotes a main body of a lighting device, in which a ballast 4 is housed, and a heat radiation hole 5 is provided on the top surface.

A reflecting plate 2 is attached to the bottom surface of the main body 1, and this reflecting plate 2
A plurality of lamps 6 (four in the figure) are mounted side by side on the same plane.

A separately made globe 7 is attached to each lamp 6 with a globe mount 8 and a thumbscrew 9 to seal each lamp for insect protection.

Each globe 7 is made from a molded product, and as shown in Figure 2, a heat radiation hole 10 is provided in one corner to completely separate this part from the lamp chamber and to seal the lamp chamber. A partition wall 11 is provided.

The four globes 7 thus formed are assembled with the corner with the heat radiation hole 10 in the center and attached to the reflector plate 2, and the reflector plate 2 directly above the heat radiation hole 10 also communicates with the inside of the main body 1. A heat radiation hole 12 is provided.

In this way, the heat radiation hole 10 provided in each glove 7
is formed in a ring shape at the center of the lighting fixture, and the partition wall 11 is attached to the outer periphery of the lamp in close contact with the reflector 2 to isolate it from the lamp chamber, preventing insects from entering the lamp chamber through the heat dissipation hole 10. In addition, the air entering from the heat radiation hole 10 passes through the heat radiation hole 12 provided in the reflector plate and cools the ballast 4 in the main body 1 as shown by the broken line in Fig. 4. The heat is discharged from the heat radiation hole 5, preventing the temperature of the ballast from rising.

In this way, it is possible to prevent the temperature of the ballast from rising and to easily provide an insect-proof structure.

FIG. 5 is an embodiment of the present invention showing a glove mounting structure that prevents the glove from being damaged due to over-tightening of the thumb screw when the glove is attached to the instrument body using the glove mount and the thumb screw.

In the figure, 13 is a reflecting plate, 14 is a glove mounting base attached to the reflecting plate, and a glove mounting screw 15 is provided on this.

16 is a glove, 17 is a thumb screw, 18 is a reflector plate 1
3 is a decorative band made by extrusion of a flexible material such as soft PVC, and when attached to the reflector plate 13,
In order to prevent the band from coming off the reflector, an undercut part 19 is formed at the lower end of the band to catch the reflector, and this part 19 extends horizontally inside the reflector so that the circumference of the globe 16 is received by the undercut part 19. be.

If this part 19 is made thin, when the glove 16 is tightened with the thumbscrew 17, this part will bend due to the tightening force, preventing excessive force from being applied to the glove, thereby preventing damage to the glove. be able to.

As described above, in this invention, the globe is separated for each lamp, so it is easy to manufacture, requires small packaging, and is convenient for storage and transportation. Since they are grouped together in one place in the center of the board, air convection is good, and the exterior looks as if it is made of a single globe, resulting in a lighting fixture with excellent design. Practical effects such as these can be obtained.
