[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION The present invention is generally called a chameleon lamp, etc., and is for a vehicle configured to be viewed as a vehicle color when it is not lit and to emit light of the specified color when the lamp is lit. It concerns lighting fixtures.

[0002]

2. Description of the Related Art FIG. 4 shows an example of the structure of a conventional vehicle lamp 90 of this type, and a rib 92 having a flat top surface 92a is provided on the back side of a lens 91. A plurality of color films 93 are provided in parallel at a predetermined interval, and a color film 93 having a desired color 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 the vehicle body color, the surface of the lens 91 is viewed as the vehicle body color when the vehicle lamp 90 is not lit. Further, when it is turned on, it shines by the color of the light source light which is emitted from between the convex portions 92 and is, for example, amber color, and the purpose as a direction indicator lamp is achieved.

[0004]

However, the lens 91 is usually provided with a mounting leg portion 94 on the outer edge for fitting with the housing 95, and the color film 93 is projected by a hot stamp or the like. Top surface 92a of the portion 92
When it is attached to the mounting leg portion 94, a clearance with the mounting leg portion 94 is required, and the color film 93 is provided inside the mounting leg portion 94.
The non-colored portion D to which the toner cannot be attached is generated.

Therefore, the portion where the non-colored portion D is generated is
When the lamp is not lit, it does not look like the desired color such as the body color, causing a problem that the viewer feels uncomfortable, and when the lamp is lit, the light source light is emitted from the entire surface of the non-colored portion D. As a result, the brightness of the surface of the lens 91 becomes non-uniform, which causes a similar feeling of strangeness, and the solution of these problems has been a problem.

[0006]

As a concrete means for solving the above-mentioned conventional problems, the present invention is provided with a rib-shaped convex portion on the rear surface of the lens, and the top surface of the convex portion is provided. In a vehicular lamp in which a color film having a color different from that of a member on which the lens is formed is formed to be viewed as a lens surface having a different color during lighting and when not lighting A gap is formed along the inner side of the mounting leg without the projection, and a shade having the same color as the color film is disposed in the gap in close contact with the mounting leg. It is fixed to the housing together with the mounting legs,
Further, there is provided a vehicular lamp characterized in that a part of the shade is fixed to the housing and extends toward the inner surface side of the lens and reaches the back surface of the gap side end of the convex portion. This solves the above-mentioned conventional problems.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described in detail based on an embodiment shown in the drawings. Reference numeral 1 in FIGS. 1 and 2 is a vehicular lamp according to the present invention. A plurality of rib-shaped convex portions 3 having a flat top surface 3a are provided on the rear side of the lens 2 of the vehicular lamp 1. Are 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 depending on whether it is on or off. Is the same as.

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

In addition to the above, in the present invention, a shade 6 is provided so as to correspond to the gap portion 5, and the shade 6 is formed in a substantially cylindrical shape along the inside of the mounting leg portion 2a. The color is formed in the same color as the color film 4 and is inserted or exposed in the gap portion 5.

Next, the operation and effect of the vehicular lamp 1 of the present invention having the above-mentioned structure will be described. Since the gap 5 is provided, the entire top surface 3a of the convex portion 3 is surely colored. Since the film 4 is formed, it is prevented that the color film 4 is not formed on a part of the convex portion 3 as in the conventional example and the color film 4 is not transparent.

At this time, the gap 5 is transparent, but since the shade 6 having the same color as the color film 4 faces the gap 5, the gap 5 is seen through. When the shade 6 is viewed from the outside, and therefore, the viewing is performed from the outside of the lens 2, the gap 5 is viewed as the same color as the portion where the convex portion 3 and the color film 4 are provided. Therefore, the color unevenness that has conventionally occurred in this portion is eliminated.

Further, since the shade 6 is made of an opaque member, when the light source 7 is turned on, that is,
When the vehicle lamp 1 is turned on, the light from the light source 7 is blocked by the shade 6 to prevent the gap 5 from shining, so that the lens 2 surface shines only on the portion where the convex portion 3 is provided. Therefore, light emission is performed with uniform brightness.

FIG. 3 shows another embodiment of the present invention. For example, when the vehicular lamp 1 is relatively large, the width H of the gap 5 is wide in terms of manufacturing and processing accuracy. There is a need to. In this case, if the shade 8 is made thick to correspond to the width H of the gap portion 5, the amount of material used increases, resulting in increase in weight or cost. The flange 8a is provided so as to extend toward the inner surface of the lens substantially parallel to the lens 2.

At this time, if the length of the flange 8a reaches the back surface of the end of the convex portion 3, the shade 8 is formed.
It is possible to prevent the gap portion 5 from being seen through without increasing the wall thickness. Since the operation and effect of this embodiment other than those described above are exactly the same as those of the previous embodiment, detailed description thereof is omitted here.

[0015]

As described above, according to the present invention, a gap is formed along the inner side of the mounting leg of the lens in which the convex portion is omitted, and the shade has the same shade as the color film. as reaching the front Kitotsu portion, the mounting leg portion that has a fixed vehicular lamp with the formation of color film to the convex portion entirely while made reliable, and colors film passes through the gap The shades of the same color are viewed, which eliminates the color unevenness that has conventionally occurred in the vicinity of the mounting legs when not lit, and when the lights are lit, the gap is shaded by the shade to emit light. It is possible to prevent the light from being emitted evenly on the lens surface, thereby preventing the viewer from feeling uncomfortable, and it is very effective in improving the quality of this type of vehicle lighting. is there.

Further, by providing a flange on the inner surface side of the shade with a length that is substantially parallel to the lens and reaches the back surface of the end of the convex portion, even when a wide gap is required for the gap portion. The shade can be formed as a thin wall without impairing the action and effect, and the effect of preventing an increase in weight or an increase in cost can also be obtained.
