Description

[Detailed explanation of the invention] (Industrial field of application) This invention relates to automobile lighting, and in particular divides one lens into multiple parts and obtains a different display color depending on the purpose of each division. The present invention relates to a so-called combination lamp which has a display effect.

(Prior art) As shown in the external view of FIG. 3, this type of lamp has, for example, clear lens a, amber lens b,
The housing c
A light source is provided inside each of them, and an independent display effect can be obtained by lighting the light sources. Therefore, there is no light leakage at the joint surface between the clear lens a and the amber lens b, and the vicinity of the boundary on the amber lens b side must not shine due to light leakage during the lighting operation of the clear lens a side. .

Therefore, in order to ensure light shielding at the boundary between both lenses, the following structure is adopted. That is, the boundary d between both lenses is first formed into a shape in which a clear lens a is provided with a convex portion a', and then an amber lens b is formed into one lens. Note that the lower part of the boundary d of the amber lens b is formed so as to surround the convex portion a'.

Then, a part of the partition wall c' of the housing c is extended to project the light-shielding ribs e and e', so that the irradiated light from the light source crosses the boundary d and reaches the light source on the side of the other lens, for example, the amber lens b. It is configured so that the irradiated light does not reach the clear lens a side.

(Problem to be solved by the invention) As mentioned above, the boundary between lenses of different colors forms a convex part a′ that protrudes obliquely on one lens, and the other lens that is in a bonded state with this convex part Since it is formed so that a part of the convex part a' is surrounded, when the boundary d between both lenses is viewed from the front or from a slightly oblique direction, the bottom face f extending in the diagonal direction of the convex part a' and the bottom face along this bottom face are visible. The wall surface g of the light-shielding rib e′ that protrudes into a ivy shape becomes a reflective surface, and as a result, the light incident from the surface side of the amber lens b is refracted and reflected toward the surface side again, and as a result, the boundary d becomes unclear and the line of the boundary d will not appear and the appearance will be seriously impaired. In particular, the light-shielding rib e' and the wall g have mirror surfaces because the reflective film applied to the inner surface of the housing c also adheres thereto, which aggravates the above effect.

(Means for solving the problem) This idea was made in order to deal with the above-mentioned situation, and the viewing side boundary of the joint between the overlapped lenses is formed on the top line of one of the light-shielding ribs. death,
This prevents the effects of refracted and reflected light near the light-shielding ribs from appearing.

(Example) In Fig. 1, 1 is the first lens, 2 is the first lens, and 2 is the first lens.
This lens is a second lens having a different color from the lens, and both lenses constitute a lens of a combination lamp for a vehicle.

Reference numeral 3 denotes a partition wall of the housing, and a light-shielding rib 3a is provided at the joint portion of the first and second lenses 1 and 2 to prevent the irradiation light from the light sources 4 and 5 from being applied to the other lens side, respectively. 3b is formed protrudingly.
The viewing side boundary 6 between the first lens 1 and the second lens 2 is formed to coincide with the top of the light shielding rib 3a. That is, the joining end 1a of the first lens 1 is molded so as to be inclined from above the top of the light-shielding rib 3a, while the surface of the second lens is formed on the top of the light-shielding rib 3a, that is, the joining end 1a. extend it to cover the bending part, and then attach both lenses 1 and 2.
The viewing side boundary 6 is formed, and the joint end 1a
It is molded to surround a part of the tip.

In the example shown in FIG. 2, a thin part 1b is formed on the first lens, and the end of the second lens 2 is extended to this part to form a viewing side boundary 6, and the light shielding rib 3a is The provision of a border 6 on the top is similar to the example of FIG.

If the first lens is clear, the second lens should be amber or red, and if the first lens is amber, the second lens should be red. In other words, when two lenses of different colors are superimposed, it is necessary to position the lens with the dominant color as the viewing side.

(Function) Therefore, even if the light incident from the surface of the second lens 2 is reflected by the wall surface 3c of the light shielding rib 3a,
The reflected light remains within the range of the second lens 2 and does not reach the first lens 1 side.

(Effect of the invention) As explained above, this invention has the first and second light-shielding ribs on the top of the light-shielding rib formed on the housing.
Since the viewing-side boundary of the overlapping lenses is provided, the first and second lenses are completely separated at the top of the light-shielding rib, and even if light incident from the lens surface is blocked, the first and second lenses are completely separated at the top of the light-shielding rib. Even if the reflected light is reflected by the wall surface of the rib, the reflected light does not cross the viewing side boundary of the joint where the first and second lenses have the dominant color and are overlapped on the viewing side.
As a result, when the lens surface is viewed from the front side, there is no inconvenience such as the boundary line becoming unclear or the colors of the two lenses mixing at the boundary, and the appearance is not impaired. .
