Description

[Detailed Description of the Invention] The present invention relates to a vehicle lamp. More specifically, the present invention relates to a combination lamp such as a rear signal having a plurality of lamp chambers.

In combination lamps with multiple lamp chambers, in order to prevent the lenses of adjacent lamp chambers from emitting light when the bulb in one lamp chamber is turned on, a light shielding plate is installed between the lenses that cover the front surfaces of the adjacent lamp chambers. is installed. In known lamps of this kind, the light shielding plate is made as an independent component, which increases the number of parts in the lamp and increases the labor involved in assembling it.

The object of the present invention is to provide a vehicle in which a part of the retroreflector used in a combination lamp is configured to double as a light shielding plate, thereby reducing the number of parts and saving labor for assembly. The goal is to obtain lamps for use.

Next, an embodiment of the present invention will be described with reference to the drawings.

The vehicle lamp of this embodiment is used as a rear signal light, and has lamp chambers 1 and 2.
Each lamp chamber is defined by a housing 3, 4 and a lens 5, 6 covering the respective front opening, the lenses 5, 6 being joined together at their edges to form an integral lens 7. It's summery.

The upper part of the edge of the joining part of the lens 5 with the other lens 6 is cut into a corner shape, and when the lenses 5 and 6 are joined, a groove 11 is formed in the front surface of the lens 7 by the cut part. do it like this. This groove 11 is formed over the entire length of the joint between the lenses 5 and 6.

A recess 7 is provided in a portion including the joining portion of the lenses 5 and 6.
a is formed in which a bracket 9 carrying a retroreflector 8 fits snugly.

That is, the bracket 9 is an opaque synthetic resin molded product and has dimensions to fit snugly into the recess 7a, and has a hanging wall on its lower surface that fits into the groove 11 formed in the front surface of the lens 7. 9a, and the depending wall has a groove 11 as shown in FIG.
The bracket 9 is formed to extend from both sides of the bracket 9 so as to fit over the entire length of the bracket 9.

The top of the peripheral wall of the retroreflector 8 is welded to the front surface of the bracket 9 by ultrasonic welding or the like to form a sealed space free from dust and water on the element side of the back surface of the retroreflector 8.

Then, the bracket 9 to which the retroreflector 8 is fixed as described above is placed in the recess 7 near the junction of the lenses 5 and 6.
a, and with the hanging wall 9a inserted into the groove 11, screws 10 are tightened to the bracket 9 from below the lens 6 to fix the bracket 9 to the lens 7.

As described above, the vehicle lamp of the present invention has a recess formed in the portion including the joint between the lenses of adjacent lamp chambers, and a groove extending over the entire length of the joint, and, on the other hand, A bracket having a hanging wall that fits into the recess near the lens joint and the groove is formed of opaque synthetic resin, and the top of the peripheral vertical wall of the retroreflector is welded onto the bracket to seal the back surface of the retroreflector. However, since the opaque bracket with the retroreflector welded and fixed thereto was fitted and fixed in the recess with its hanging wall inserted into the groove, the opaque bracket could be used as a light shielding member on the back side of the retroreflector. It can also be used as a light shielding member between lenses in adjacent lamp chambers. That is, in the present invention, since the top of the peripheral standing wall of the retroreflector 8 is welded onto the opaque bracket, it is theoretically possible to shield the back surface of the retroreflector from light by the bracket. The hanging wall is inserted into the groove formed over the entire length of the joint between the lenses, so that when one lamp chamber is turned on, the light passes through the lens and reaches the lens side of the other lamp chamber. Light that is about to leak can be reliably blocked by the hanging wall.

As described above, according to the vehicle lamp of the present invention, the bracket 9, which is a light-shielding sealing member on the back side of the retroreflector, functions as a light-shielding plate between the lenses 5 and 6. It is no longer necessary to provide a light-shielding plate between the lenses as an independent component, and the number of parts can be reduced, as well as the number of man-hours required for installing the light-shielding plate.

Claims (1)

[Scope of utility model registration request] In a vehicle lamp having multiple lamp chambers,
A recess is formed in a portion of the adjacent lamp chamber that includes a joint between the lenses, and a groove extending over the entire length is formed in the joint, while fitting into the recess near the lens joint and the groove. A bracket having a hanging wall is formed from an opaque synthetic resin, and the top of the peripheral standing wall of the retroreflector is welded onto the bracket to seal the back surface of the retroreflector, thus making the opaque bracket with the retroreflector fixed by welding. The hanging wall is fitted and fixed in the recess with the hanging wall inserted into the groove, and the opaque bracket having the hanging wall is connected to the light shielding member on the back surface of the retroreflector and the light shielding member between the lenses of the adjacent lamp chambers. A vehicle lamp characterized in that it can be used for both purposes.
