Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a front lens of a vehicle lamp whose peripheral edge is brightly treated, and in particular, a band-shaped hot stamp foil layer is applied to the peripheral edge by hot stamping. The present invention relates to a front lens in which a brightly treated area is formed.

[Prior art and problems to be solved by the invention]

In conventional lamps, for example heat lamps, the fourth
As shown in the figure or FIG. 5, resin or metal moldings 4, 4a, 4b that have been subjected to brightening treatment (surface plating treatment) are attached to the peripheral edge of the front lens 2 to give it a luxurious image. I was getting used to it.

However, in this conventional method, it is necessary to assemble the molding 4, which is a separate member, around the front lens 2, and setting the mounting position of the molding 4 with respect to the front lens 2 and assembling the molding 4 are troublesome, which increases the workability. There was a problem that it was bad.

The present invention was devised in view of the problems of the prior art described above, and improves workability by directly forming a brightly treated area corresponding to the molding on the front lens. The object of the present invention is to provide a vehicle lamp that does not affect the functions of the vehicle.

[Means to solve the problem]

In order to achieve the above object, the present invention includes a strip-shaped protrusion that is integrally formed along the peripheral edge, and a hot stamp foil layer, a clear coat layer, and a hard coat layer that are sequentially laminated on the surface of this protrusion. A front lens of a vehicle lamp is provided with a brightly treated area formed therein, and a black coating is provided on the side edge of the lens adjacent to the hot stamp foil layer so that the edge contacts the hot stamp foil layer. It is characterized in that at least a part of the coating is covered with the hard coat layer.

[Effect]

Since the brightly treated area, which is mainly a hot stamp foil layer, is formed directly on the front lens, there is no need for a separate component equivalent to a molding, which reduces the number of parts that make up the lamp, and makes it easier to assemble the lamp. Become.

The brightly treated area also has excellent weather resistance and abrasion resistance due to the hard coat layer formed on the hot stamp foil layer. Furthermore, in the present invention, a black coating is provided on the side edge of the lens adjacent to the hot stamp foil layer, the edge of which comes into contact with the hot stamp foil layer, and at least a portion of the black coating is covered with a hard coat layer. Therefore, when the lamp is turned on, light leaks from the outside of the hot stamp foil layer,
The generation of harmful light that does not contribute to the light distribution necessary for driving is prevented, and the hard coat layer simultaneously protects the black paint and the hot stamp foil layer.

〔Example〕

Next, embodiments of the present invention will be described based on the drawings.

Figures 1 to 3 show the application of the present invention to the front lens of an automobile headlamp. FIG. 3 is an enlarged cross-sectional view of the brightly treated area, which is the main part.

In these figures, numeral 10 is a front lens made of synthetic resin such as acrylic or polycarbonate.
It is assembled into a seal groove 14 formed at the periphery of the front opening of a container-shaped lamp body 12 to be integrated as a headlamp.
The front side of the front lens 10 has upper and lower side edges 10.
A, 10c and a band-shaped protrusion 16 that continuously extends in a U-shape along the side edge 10b on the vehicle center side.
It is formed integrally with the front lens 10 , and a brightly treated area 20 is formed on the front end surface of this protrusion 16 . The brightness treatment area 20 includes an upper edge brightness area 20a along the upper edge 10a of the front lens, a vehicle center side edge brightness area 20b along the vehicle center side edge 10b of the front lens, and a lower edge brightness area 20b along the vehicle center side edge 10b of the front lens. The lower edge bright area 20c along the side edge 10c is continuous in a U-shape and looks like a brightly treated frame member surrounding the front lens 10.

As shown in FIG. 3, the brightly treated area 20 includes, in order from the bottom, a hot stamp foil layer 22,
It has a structure in which a clear coat layer 24 and a hard coat layer 26 are laminated. The hot stamp foil layer 22 is formed by adhering a chrome-like hot stamp foil to the front end surface of the protrusion 16 of the front lens 10 by hot stamping. Further, the clear coat layer 24 is formed by the hot stamp foil layer 2.
A clear (colorless and transparent) paint such as urethane-based, acrylic-based, or epoxy-based paint is coated (printed) on the surface of 2. Also, hard coat layer 2
6, a hard film of acrylic or silicone is formed on the clear coat layer 24. Further, a black urethane coating 25 is applied all around the side wall of the front lens 10 so that its edge is in contact with the hot stamp foil layer 22, and this black urethane coating 25 and the peripheral edge of the front lens are lapped. As such, the hard coat layer 26 is formed over a portion of the front surface and side edges of the front lens 10. Reference numeral A indicates the area where the black urethane coating 25 and the hard coat layer 26 overlap.

Note that the brightly treated area 20 is the hot stamp foil layer 2.
2. Clear coat layer 24, hard coat layer 26
The reason why the layers are formed in this order is as follows.

In order to improve the weather resistance and abrasion resistance of the front lens, it is common practice to form a hard coat layer on the surface of the front lens. However, when the hot stamp foil layer 22 is formed on the hard coat layer 26, In this case, the adhesion of the hot stamp foil is poor, and when the hard coat layer 26 is formed directly on the hot stamp foil layer 22, the hard coat layer 2
6 has poor adhesion, and the hard coat layer 26 easily peels off, the hard coat layer peels off and looks bad, and the surface is easily scratched. A layer 26 is formed.

In the step of applying the brightening treatment to the front lens 10 described above, first, a front lens having a shape in which the protrusion 16 is formed on the peripheral edge is molded with resin. Next, hot stamp foil is adhered to the protrusion 16 of the front lens by hot stamping to form a hot stamp foil layer 22. and if necessary,
An annealing process is performed to remove distortion within the front lens 10. Next, a clear coat layer 24 is applied on top of the hot stamp foil layer 22 formed on the peripheral edge of the front lens.
At the same time, a black urethane coating 25 is applied to the entire outer wall of the front lens 10. Finally, a hard coat layer 26 is applied to the entire front surface of the front lens 10 including the clear coat layer 24 and a predetermined side edge area.
is formed, and the front lens 10 shown in FIGS. 1 and 2 is completed.

[Effect of idea]

As is clear from the above description, according to the vehicle lamp according to the present invention, a band-shaped protrusion is integrally formed with the front lens along the peripheral edge of the front lens, and a hot stamp is applied to the surface of the protrusion. Since the glitter-treated area is formed by sequentially laminating a foil layer, clear coat layer, and hard coat layer, there is no need for a member equivalent to the conventional glitter-treated molding, which reduces the number of parts in the lamp. , the workability of assembling the lamp is improved.

Furthermore, since a hard coat layer is formed on the hot stamp foil layer, the molding is superior to conventional brightly treated moldings in terms of weather resistance and abrasion resistance. Furthermore, the side edge of the lens adjacent to the hot stamp foil layer is provided with a black coating that the edge contacts with, and at least a portion of this black coating is covered with a hard coat layer, so that the lamp When the vehicle is turned on, light leaks from the outside of the hot stamp foil layer, which prevents the generation of harmful light that does not contribute to light distribution for driving, and simultaneously protects the black coating and the hot stamp foil layer.
