Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to an improvement of a vehicle lamp.

[Conventional technology]

Conventionally, in this type of lamp, as shown in FIG. 5, the periphery of a metal reflector 12 to which a socket 11 is crimped and fixed is placed on a mounting boss 14 integrally formed within a base 13, and a frame-shaped A lens 16 ultrasonically welded to a lens holder 15 is screwed to the mounting boss 14 via the metal reflector 12, and the lens holder 15 is pressed against the periphery of the opening of the base 13. A gasket 17 is provided between the lens holder 15 and the periphery of the opening of the base 13 in order to prevent water from entering the inner surface of the reflector.

[The problem that the idea aims to solve]

However, in the conventional lighting equipment described above, when assembling the lighting equipment, when screwing the lens to the base,
Since the reflector must be temporarily fixed to the base in advance, and a ring-shaped gasket is placed on the end face of the periphery of the opening of the base, and then the lens holder is placed on top of this, there is a risk that the gasket may shift during the screw fixing process. However, reflectors are generally manufactured by press-forming metal materials, and this press-forming process does not allow for slight changes in shape. Therefore, it is currently impossible to provide multiple parabolic reflecting surfaces on the inner surface of the reflector, each of which has a slightly different shape, and this has the disadvantage that it is not possible to make the lamp thinner. .

The purpose of the present invention is to facilitate the assembly work of the lamp and to make the lamp thinner by using a reflector that can form multiple parabolic reflection surfaces.

[Means to solve the problem]

The present invention was devised in consideration of the above-mentioned disadvantages of the conventional method, and includes a frame-shaped lens holder formed integrally with the front opening periphery of a reflector molded from synthetic resin, in which a lens is inserted into a frame-shaped lens holder, and A light bulb is attached to a socket which is crimped and fixed in the socket attachment hole of the reflector, and the lens and reflector are screwed to a mounting piece provided on the inner surface of the side wall of the base that covers the reflector and the socket. The object of the present invention is to provide a vehicular lamp that solves the conventional disadvantages.

[Effect]

In this invention, the reflector is molded from synthetic resin, making it possible to provide multiple parabolic reflection surfaces on the inner surface of the reflector, and the reflector and lens holder are integrated, making it easier to assemble the lamp. become.

〔Example〕

Next, the present invention will be explained in detail based on an embodiment shown in FIGS. 1 to 4.

The lamp 1 is composed of a lens 2, a reflector 3, a light bulb 4, a socket 5, and a base 6. The reflector 3 is molded from synthetic resin and has multiple parabolic reflection surfaces 30 on its inner surface. As shown in FIG. 3, a frame-shaped lens holder 7 corresponding to the shape of the lens 2 is integrally formed on the periphery of the opening of the reflector 3, and a socket mounting hole 31 formed at the rear of the reflector 3 is provided with a frame-shaped lens holder 7. In this case, the socket 5 is crimped and fixed, and the light bulb 4 is attached. The lens 2 is inserted into the lens holder 7 by fitting the peripheral edge of the lens 2 into a groove 70 provided across the inner peripheral edge of the lens holder 7 via the lens gasket 2a. There is. Said base 6
is molded from synthetic resin and is provided so as to cover the reflector 3 and the socket 5 so that its opening periphery comes into contact with the lens holder 7. A mounting piece 61 that protrudes inward and has a screw insertion hole 62 is integrally formed near the opening periphery of the inner surface of the left and right side walls 60 of the base 6, and the screw 8 is inserted into the mounting piece 61. A U-nut 63 for threading is attached.

In assembling the lamp 1, the lens 2 is temporarily fixed to the reflector 3 by inserting the lens 2 into the lens holder 7 via the lens casket 2a that spans the inner peripheral edge of the lens holder 7. The screw insertion parts 20 provided on both the left and right sides of the lens 2 match the screw insertion parts 32 of the reflector 3 provided corresponding to the mounting piece 61, and the screw insertion parts 32 are placed on the mounting piece 61. Then, connect the screw insertion part 20 of the lens 2 and the reflector 3.
The lamp 1 is formed by passing the screw 8 through the screw insertion portion 32 of the lens 2 and fixing the lens 2 and reflector 3 to the mounting piece 61 with screws.

[Effect of idea]

As explained above, in the present invention, a lens is inserted into a frame-shaped lens holder that is integrally formed around the front opening of a reflector made of synthetic resin, and is fixed by crimping into a socket mounting hole of the reflector. A light bulb is mounted in the socket, and the lens and reflector are screwed to a mounting piece provided on the inner surface of a side wall of a base that covers the reflector and socket. Therefore, according to the present invention, since the reflector is molded from synthetic resin, multiple parabolic reflecting surfaces can be provided on the inner surface of the reflector, and the lamp can be made thinner. In addition, by screwing the reflector to which the lens is temporarily fixed to the base, the lamp is assembled, and a lens gasket can be placed over the inner periphery of the lens holder where the lens fits, allowing the lens gas to perform this sealing function. The gasket does not easily shift even during the screw fixing process described above, and the gasket that was conventionally placed between the lens holder and the periphery of the opening of the base and was prone to shift can be eliminated, making the assembly process of the lamp much easier. This has excellent practical effects such as simplicity.
