Description

[Detailed description of the invention] <<Industrial Application Field>> The present invention relates to a vehicle lamp in which multiple light chambers are arranged adjacent to each other, such as a rear combination lamp. The present invention relates to a vehicular lamp equipped with an outer lens.

<Prior art> As one of the rear combination lamps, a colorless or light smoke-like transparent outer lens is attached to the front of the housing, and a plurality of light bulbs each having a different predetermined color in a double structure are attached to the front of the housing. A structure is known in which an inner lens is attached to define a plurality of lamp chambers, and lamp bulbs are arranged within these lamp chambers. In this rear combination lamp, a Fresnel prism is usually formed on the inner surface of each inner lens, and a fisheye prism is formed on the outer surface of the inner lens to obtain appropriate diffused light.

<Problems to be Solved by the Invention> Incidentally, in such a rear combination lamp, in order to block light between the respective lamp chambers, for example, a groove is formed at the boundary portion of each lamp chamber on the front surface of the housing, and a groove is formed in the outer lens. A bent part with a U-shaped cross section that is inserted into the groove is formed in the part facing the groove, and a molding is installed in the front recess of this bent part, so that the housing and the molding are connected to each other through the bent part. They are arranged in a nested manner.

However, in the case where the outer lens is continuous between the lamp chambers via its bent portion, especially since the outer lens is almost colorless and transparent, lighting of one lamp chamber causes the inner lens wall thickness to increase. A so-called edge light occurs in which the light is transmitted to the adjacent lamp chamber. This is because the back surface of the bent portion formed on the outer lens acts as a light-condensing surface, and this edge light may obscure the lighting of signal lights, which is necessary especially during the day, leading to misunderstandings. However, there is a problem in that the aesthetic appearance when the lamp is lit is impaired.

In view of these circumstances, it is an object of the present invention to provide a vehicular lamp that can prevent edge light caused by the outer lens.

<Means for Solving the Problems> In other words, in order to solve the above-mentioned problems, the present invention attaches a plurality of inner lenses each having a predetermined light color to the front surface of the housing to define a plurality of light chambers. A vehicle lamp is provided in which lamp bulbs are disposed within these lamp chambers, and an integrated transparent outer lens with a colorless or pale smoke tone is attached to the front surface of each of the inner lenses, and a groove portion is provided at the boundary portion of each light chamber on the front surface of the housing. a bent portion having a U-shaped cross section that is inserted into the groove, and a protruding piece portion that is partially inserted into the bent portion on the front surface of the outer lens; A cross section T having an extension part extending to both light chamber sides
It is characterized by a letter-shaped molding.

<<Operation>> With the above configuration, the vicinity of the bent portion of the outer lens where edgelight occurs is covered by the molding.

《Example》 The vehicle lamp according to this example is configured as a rear combination lamp, and as shown in Fig. 1, a common outer lens 2 is attached to the front opening of the housing 1, and a double By attaching a plurality of inner lenses 3 and 4 each having a different predetermined lamp color in structure and further closing the rear surface of the housing 1 with a back cover 5, a plurality of lamp chambers are defined, and a lamp bulb is installed in each lamp chamber. 6 is arranged.

The housing 1 includes an outer peripheral portion surrounding each lamp chamber;
A boundary portion is provided which is connected to the outer circumferential portion and partitions each lamp chamber. An annular groove 8 into which an adhesive 7 for attaching the outer lens 2 is injected is formed on the front surface of the outer peripheral portion. Further, on the front side of the boundary part, a bent part 9 provided on the outer lens 2 and this bent part 9 are provided in order to block light between the respective lamp chambers.
A wide groove 11 is formed into which a molding 10 that is attached from the outside is inserted.

Further, the outer lens 2 is formed by containing, for example, a certain amount of carbon in a transparent synthetic resin such as acrylic, so that a light smoke-like outer lens is transparent and integrally formed like a cover lens. The outer lens 2 is attached to the housing 1 by inserting the leg portions 12 formed on the peripheral edge into the groove portion 8 and fixing them with the adhesive 7. The portion of the outer lens 2 corresponding to the groove 11 is
The above-mentioned bent portion 9 is bent and inserted into the groove portion 11 side with a substantially U-shaped cross section. This bent part 9
is formed over the entire length of the groove portion 11. The back side of this bent portion 9 is formed to have a rectangular cross section corresponding to the groove portion 11, as shown in FIG. Further, on the front side of the bent portion 9, a substantially T-shaped front recess 1 is formed with a deep groove portion 13a in the center and shallow bottom portions 13b on both sides.
3 is formed. The front recess 13 is such that the interval X from one end of the shallow groove 13b to the other is sufficiently larger than the width Y of the bent part 9, and extends toward each of the lamp chambers.

Further, the molding 10 is made of opaque synthetic resin, and has a deep groove 13 corresponding to the front recess 13.
A cross section approximately T in which the protruding piece 10a inserted into the a and the extending part 10b inserted into the shallow bottom part 13b are connected.
It is shaped like a letter. This molding 10 is fixed to the outer lens 2 by, for example, joining the tip of the projecting piece 10a to the bottom of the deep groove 13a by high frequency welding or the like.

As shown in FIG. 3, the molding 10 partitions the surface of the outer lens 2, and the vicinity of the boundary of each lamp chamber is covered by the extending portions 10b on both sides extending toward each lamp chamber. This prevents the edge light generated in this area from emitting light forward.

Further, the protruding piece 10a of the molding 10 has a first
As shown in the figure, it is inserted into the groove 11 via the bent portion 13 and placed between the side walls of the groove 11, thereby shielding light between the respective lamp chambers.

Further, each of the inner lenses 3 and 4 is fixed between the inner wall of the outer peripheral portion and the side wall of the boundary portion of the housing 1 by, for example, high frequency welding or screwing.

Furthermore, the back cover 5 also has a structure that partitions each light chamber, and is attached with screws or the like.

<<Effects of the Invention>> According to the present invention, by covering the vicinity of the bent portion of the outer lens where edge light is generated with the extension portion formed on the molding, it is possible to prevent the edge light from emitting forward light.
