Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a lighting device for a vehicle, and particularly to a lighting device provided on the outer surface of a vehicle body.

[Prior art] In recent years, lights have been installed near the rear window glass, at the rear end of the roof, and at the rear end of the trunk lid, as exemplified by a light fixture called a high-mounted stop lamp, to speed up the next operation of the vehicle. This information was communicated to following vehicles and drivers to prevent accidents such as collisions.

In addition, lights installed on the outside of the vehicle, such as headlamps, are designed to prevent rainwater from rain or water from washing the car from entering the light, and to make it possible to replace the light bulb if it breaks. It is set up like this.

[Problems to be solved by the invention] However, a long lamp with a large number of lamps arranged in the width direction of the vehicle is installed at the rear end of the roof or the rear end of the trunk lid across the width of the vehicle. When attempting to improve visibility, the lamp itself is long, such as being installed across the width of the vehicle, resulting in poor sealing performance, making it impossible to achieve both sealing performance and ease of maintenance. Due to these drawbacks, it has not been possible to realize a long lamp that is mounted on the outer surface of the vehicle body.

[Means for Solving the Problems] The present invention has been made in consideration of the above-mentioned drawbacks of the conventional technology. a plurality of lamps inserted from the rear into the lamp mounting holes of the lamp, and a long gasket for concealing the rear part, and a jetty surrounding the rear part is integrally provided on the outer periphery of the rear part, and A plurality of locking protrusions are provided on the outer circumferential surface of the jetty, and the seal engages with the locking protrusion and a fitting portion having a plurality of protrusions that press against the inner circumferential surface of the jetty in a circumferential direction. It is an object of the present invention to provide a vehicular lamp characterized by comprising an outer circumferential wall portion having a recessed portion, thereby solving the above-mentioned conventional drawbacks.

[Function] In the present invention, the plurality of protrusions provided on the fitting part of the seal press against the inner peripheral surface of the jetty to seal the rear part where the lamp is attached from the outside,
Also, by removing the gasket, the lamp could be replaced.

[Example] Next, the present invention will be described in detail based on an example shown in FIGS. 1 to 3.

In the figure, reference numeral 1 denotes an elongated lamp, which is mounted on the outer surface of the vehicle body in the width direction of the vehicle, for example, via a rear spoiler provided on the trunk lid. As shown in FIG. 1, the lamp 1 includes a lamp housing 2 that is elongated in the vehicle width direction, a large number of lamps 4, and the lamps 4.
a flexible printed circuit board 6, and a gasket 7 made of an elastic material and provided in a long length corresponding to the lamp housing 2.
It is formed from.

In the lamp housing 2, a lens 3 is fixed to a front part 20 by welding or adhesive, and a large number of lamp mounting holes 22 are arranged in a longitudinal direction in a rear part 21. and socket 5
Each of the lamps 4 mounted on the lamp housing 2 is inserted into the lamp mounting hole 22 from the rear of the rear part 21, and the socket 5 is removably fitted into the lamp mounting hole 22, so that a large number of lamps 4 are arranged in a row in the lamp housing 2. It is provided within.

The printed circuit board 6 is attached to the rear surface of the rear portion 21 in the longitudinal direction, and is elongated, and is provided with a plurality of holes corresponding to each of the lamp mounting holes 22. When the socket 5 is fitted into the lamp mounting hole 22, the flange 50 at the rear end of the socket presses the printed circuit board 6 toward the rear section 21, and the printed circuit board 6 is held between the socket 5 and the rear section 21. That's what I do. Furthermore, the lamp 4 and the printed circuit board 6 are connected by the printed circuit board 6 and the flange 50 coming into contact with each other.

As shown in FIG. 1, a jetty 8 surrounding the rear portion 21 is integrally provided on the outer peripheral edge of the rear portion 21 of the lamp housing 2, and a plurality of locking protrusions are provided over the outer peripheral surface of the jetty 8. 80 are provided.

The packing 7 is fitted into a recess a surrounded by a jetty 8, and the locking protrusion 80 engages with a fitting part 70 that hides the socket 5 and the printed circuit board 6, that is, the rear part 21. recess 73
It consists of an outer peripheral wall part 72 which has on the inner peripheral surface and covers the jetty 8. A plurality of protrusions 71 extending in the circumferential direction are formed on the circumferential surface of the insertion portion 70, and the cross-sectional shape of the circumferential surface is provided in a sawtooth shape. When the fitting part 70 is fitted into the recess a, the respective protrusions come into pressure contact with each other in the circumferential direction of the inner circumferential surface of the jetty 8, thereby reliably sealing the rear part 21 from the outside. Further, the outer peripheral wall portion 72 with which the locking protrusion 80 engages
is removed from the locking protrusion 80 by pulling the lamp 1 open in the vertical direction, and is normally engaged with the locking protrusion 80 to prevent the gasket 7 from falling off. This can be easily done by removing the part 72 from the locking protrusion 80 and removing the gasket 7 from the lamp housing 2.

Note that the lamp in one embodiment may be made of a microbulb or may be made of a light emitting diode.

[Effect of the invention] Therefore, according to the invention, since the plurality of protrusions provided on the fitting portion of the packing are in pressure contact with each other in the circumferential direction of the inner circumferential surface of the jetty, In addition to achieving uniform and good sealing performance, the seal can be removed by removing the outer peripheral wall of the seal from the locking protrusion without using any tools, making it easier to perform maintenance such as lamp replacement. This makes the work easier, and it is possible to obtain a lamp that is long in the vehicle width direction and has a simple structure.
