Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention is a lens made by integrating a transparent lens part and an amber lens part. The present invention relates to an automobile lamp having a vehicle lamp.

0002

[Conventional technology]

Conventionally, as an automobile light fixture installed on both sides of the front of a car, the light fixtures shown in Figs. 3 and 4 are used. A lens 3 formed by bonding and integrating a transparent lens portion 1 and an amber lens portion 2 as shown in FIG. It is known that it has

0003 In such automotive lighting equipment, the colored light must not be visible from the rear of the vehicle. In order to comply with the standard (ECE Regulation 76/756 in Europe) that , it is necessary to apply a light-shielding coating 4 to a part of the transparent lens part 1 (the grid line part in FIG. 3). .

0004 By the way, in conventional automobile lamps, an amber lens part is used as shown in FIG. A transparent lens part 1 having a protrusion 1a on the joint surface with 2 to increase the joint strength is attached to the It is preformed before the amber lens part 2. Then, this transparent lens part 1 is molded into a mold. The amber lens part 2 is integrally molded with the transparent lens part 1, and the transparent lens The protruding strip 1a of the lens part 1 was fitted into the concave strip 2a of the amber lens part 2. Therefore, masking 5 is applied to the amber lens part 2, and a part of the transparent lens part 1 is When applying the light-shielding coating 4, the coating will overlap the transparent lens portion 1 and the amber lens portion 2. By seeping through the seam 6, cracks occur in the seam 6.

[0005] Therefore, as shown in FIG. Even if the concave part 7 for paint separation is provided at a position adjacent to the seam 6, the paint will not leak from the seam 6. It soaks in and cracks occur at seam 6.

[0006] Therefore, as shown in FIG. A recess 7 for painting parting is provided at a position spaced apart from the seam 6, and from this recess 7 If masking 5 is applied to the amber lens part 2 including the eye 6, the coating from the seam 6 will be removed. This prevents the material from seeping in and reliably prevents cracks from forming at seam 6. .

[0007]

[Problem that the idea aims to solve]

However, the portion 1b located between the concave portion 7 and the seam 6 of the transparent lens portion 1 is shielded. Since no optical coating is applied and it remains transparent, the light from the bulb 8 is reflected by the reflector 9. If this occurs, colored light is emitted from the portion 1b, and it no longer conforms to the above-mentioned standards. There was a problem.

[0008] This invention was developed in view of the above circumstances, and white light should not be seen from the rear of the car. Although it can comply with the standard that the transparent lens part and the amber layer must not be To ensure that cracks do not occur due to seepage of the light-shielding paint at the joint with the lens part. The purpose of the present invention is to provide a lighting device for an automobile that can perform

[0009]

[Means to solve the problem]

In order to achieve the above purpose, the automotive lamp of the present invention has a transparent lens part and an amber lens. In the automotive lamp having a lens formed by bonding a lens portion with a lens portion, the transparent lens portion A grooved portion is provided on the bonding surface of the amber lens portion, and the grooved portion is provided on the bonding surface of the amber lens portion. The device is characterized by being provided with a protrusion that engages with the ridge.

0010

[Effect]

Amber lens part Because the protrusion part that is a part of the lens is inserted, the amber lens part of the transparent lens part and A recess for painting parting is provided at a position away from the seam, and the seam is drawn from this recess. By masking the amber lens part, including the amber lens part, the paint will seep in. In addition to reliably preventing the occurrence of cracks at the seams, the light from the bulb is transmitted through the transparent lens. The protrusion of the amber lens part that fits into the groove between the concave part and the seam. Because it passes through the light, amber light is emitted instead of white light.

[0011]

【Example】

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. Figure 1 shows the structure of this invention. FIG. 2 is a side view of the main parts of the vehicle lamp, and is a cross-sectional view taken along line II-II in FIG. 1. In both figures, 10 is a lens, which is made by joining a transparent lens part 11 and an amber lens part 12 together. Become. That is, there is a dovetail groove on the joint surface with the amber lens part 12 to increase the joint strength. The transparent lens portion 11 having the grooved portion 11a is prepared in advance before the amber lens portion 12. Form it. Then, this transparent lens part 11 is set in a mold, and an amber The lens part 12 is integrally molded with the transparent lens part 11 and is a part of the amber lens part 12. A certain protrusion 12a is in a fitted state. Amber of transparent lens part 11 A recessed part 14 for painting parting is provided at a position spaced apart from the joint 13 with the lens part 12. , Masking 1 is applied to the amber lens portion 12 from this concave portion 14 to the seam 13. 5, and a light-shielding coating 16 is applied to the transparent lens portion 11. In addition, in Figure 1, case The area where the lattice lines are applied and the arrow A and B areas in FIG. 2 are the areas where the light shielding coating 16 was applied. It becomes.

0012 Therefore, the amber lens portion 12 is masked from the concave portion 14 to the seam 13. The transparent lens portion 11 can be coated with a light-shielding coating 16 by applying coating 15. The light-shielding paint does not seep into seam 13, preventing cracks from forming at seam 13. It is possible to reliably prevent death. Further, the light from the light bulb 17 is reflected by the reflector 18 and becomes an amplifier. Since it passes through the protruding portion 12a that is a part of the bar lens portion 12, it is not white light; It emits an amber light.

[0013]

[Effect of the idea]

As described above, the automotive lamp of the present invention connects the transparent lens part and the amber lens part. In an automotive lamp having a lens formed by combining the transparent lens portion with the A grooved portion is provided, and the grooved portion is engaged with the bonding surface of the amber lens portion. It is characterized by the provision of a protrusion.

[0014] Therefore, the light-shielding paint soaks into the joint between the transparent lens part and the amber lens part. In addition to preventing cracks from occurring at this seam, the reflector The reflected light passes through the ridges that are part of the amber lens, so white light cannot The white light must not be visible from the rear of the car, as it emits an amber light. It can meet the standard.
