Abstract

(57) [Abstract] [Purpose] When a light is turned on and off when a rib-shaped convex portion is provided on the back side of a conventional lens and a color film of a color different from the color formed by the lens is formed on the top surface. In the vehicular lamp that is viewed as a lens surface having different colors, there is a problem in that a portion where the color film cannot be formed is generated in the vicinity of the peripheral edge of the lens, resulting in color unevenness. According to the present invention, a gap 5 is provided along the inside of the mounting leg 2a of the lens 2, and a coating film 6 having the same color as the color film 4 is provided in the gap 5 at the end of the convex portion 3 and the mounting leg. By providing the vehicular lamp 1 including the inside of the portion 2a, the formation of the color film 4 on the entire surface of the convex portion 3 is ensured, and the coating film of the same color as the color film 4 formed in the gap 5 is formed. Let you see 5
This eliminates the color unevenness that occurs in the vicinity of the mounting leg portion 2a when the lens 2 is not lit, and prevents the light from being emitted from this portion by blocking the gap 5 with the coating film 6 when the lens 2 is lit.
To solve the problem by enabling uniform light emission on the surface.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention is generally called a chameleon lamp or the like, and relates to a vehicular lamp which is configured to be viewed as a vehicle body color or the like when it is not lit and to emit light of a specified color which is the purpose of the lamp when the lamp is lit.

[0002]

[Prior art]

 An example of the configuration of a conventional vehicle lamp 90 of this type is shown in FIG. 3, and a plurality of rib-shaped convex portions 92 having a flat top surface 92a are provided on the rear side of the lens 91 in a predetermined manner. It is provided in parallel at intervals, and a color film 93 having a color desired to be viewed when not lit is attached to the top surface 92a by an appropriate means such as a hot stamp.

At this time, if the lens 91 is formed of a colorless and transparent member and the color film 93 is formed of a vehicle body color, the surface of the lens 91 is in the vehicle body color when the vehicle lamp 90 is not lit. When the light is turned on, the light shines by the color of the light source light, for example, amber color, emitted from between the convex portions 92, and the purpose as a direction indicator light is achieved.

[0004]

[Problems to be solved by the device]

 However, the lens 91 is usually provided with a mounting leg portion 94 at the outer edge for fitting with the housing 95, and the color film 93 is attached to the top surface 92a of the convex portion 92 by hot stamping or the like. In some cases, a clearance with the mounting leg portion 94 is required, and a non-colored portion D where the color film 93 cannot be attached to the inside of the mounting leg portion 94 is generated.

Therefore, the portion where the non-colored portion D is generated does not look like a desired color such as a vehicle body color when the lamp is not lit, which causes a problem that the viewer feels uncomfortable. The light from the light source is emitted from the entire surface of the non-colored portion D, which causes unevenness of the luminance on the surface of the lens 91 and also causes a feeling of strangeness, and it is a problem to solve these problems. It was supposed to be.

[0006]

[Means for Solving the Problems]

 As a concrete means for solving the above-mentioned conventional problems, the present invention is a member in which a rib-shaped convex portion is provided on the back surface of the lens, and the lens is formed on the top surface of the convex portion. In a vehicular lamp that has a color film of a color different from that of the above, and is viewed as a lens surface with different colors when illuminated and when not illuminated, the convex portion is formed along the inside of the mounting leg of the lens. An omitted gap portion is provided, and a coating film having the same color as the color film is applied to the gap portion including the end portion of the convex portion and the inside of the mounting leg portion. The problem is solved by providing a vehicular lamp.

[0007]

【Example】

 Next, the present invention will be described in detail based on an embodiment shown in the drawings. 1 and 2 is a vehicular lamp according to the present invention, and a rib-shaped convex portion 3 having a flat top surface 3a is provided on the rear side of the lens 2 of the vehicular lamp 1. Is provided in parallel with each other, and a color film 4 is formed on the top surface 3a by a hot stamp or the like so that the lens 2 surface can be viewed as different colors when lighting and when not lighting. Similar to the example.

Here, in the present invention, the gap 5 is formed along the inner side of the mounting leg 2 a provided on the lens 2 and the convex 3 is not provided, and the width H of the gap 5 is Is equal to or slightly larger than the amount of clearance required when performing hot stamping described in the conventional example. Therefore, the color film 4 is attached to the entire top surface 3a of the convex portion 3. It is supposed to be possible.

A coating film 6 formed by coating an opaque paint is formed in the gap 5 formed as described above, and the coating film 6 has the same color as the color film 4. Thus, the inner surface of the mounting leg portion 2a and the end surface of the convex portion 3 are provided, and thus the entire gap portion 5 is covered with the coating film 6.

Next, the operation and effect of the vehicular lamp 1 of the present invention having the above-described structure will be described. First, since the gap portion 5 is provided, the entire top surface 3a of the convex portion 3 is covered. Thus, the color film 4 is surely formed, and it is possible to prevent the color film 4 from being formed in a part of the convex portion 3 as in the case of the conventional example, which is not transparent.

At this time, the gap 5 is naturally transparent, but since the coating film 6 having the same color as the color film 4 is formed in the gap 5, the gap 5 is transparent. However, when viewed from the outside of the lens 2, the gap 5 has the same color as the portion where the convex portion 3 and the color film 4 are provided. As a result, the color mura that has been generated in this part when the lamp is not lit is eliminated.

Incidentally, when the coating film 6 is provided, the gap 5 is provided at the corresponding portion, so that the portion where the coating film 6 is provided becomes flat and the position becomes clear. The finished surface will be beautiful and masking during painting will be easy.

In addition, since the coating film 6 is formed of an opaque paint when the vehicle lamp 1 is turned on, light from the light source 7 is not emitted through the gap 5. Therefore, the surface of the lens 2 is radiated only from the portion where the convex portion 3 is provided, so that the surface of the lens 2 shines with uniform brightness.

[0014]

[Effect of device]

 As described above, according to the present invention, a gap portion is provided along the inside of the mounting leg portion of the lens, and a coating film having the same color as the color film is provided in the gap portion at the end of the convex portion and the inner side of the mounting leg portion. By including the vehicle lamp, it is possible to ensure that the color film is formed on the entire surface of the convex portion, and at the same time, to view the coating film of the same color as the color film formed in the gap. In the past, color unevenness that had occurred in the vicinity of the mounting legs when not lit was eliminated in the past, and at the time of lighting, the gap was covered with a paint film to prevent light from being emitted from this part. It is possible to achieve uniform light emission on the surface, prevent the viewer from feeling uncomfortable, and have an extremely excellent effect in improving the quality of this type of vehicular lamp.
