DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a housing, in which a lens is mounted on a front opening of the housing, a bulb is mounted on the housing, and a reflector having a multi-stage reflecting surface is provided on an inner wall surface of the housing. The present invention relates to a vehicular lamp provided with a colored transparent cap to cover.

[0002]

Conventionally, for example, a turn signal lamp provided in the rear combination lamps, 5
As shown in FIG.
Are mounted on the housing 1, and the multi-stage reflecting surface 4a (for example, Reflector 4 with aluminum deposition)
Is provided, and is colored and transparent (for example,
A vehicular lamp 6 provided with an amber-colored cap 5 is known.

[0003]

By the way, in the vehicle lamp 6 constructed as described above, the color of the cap 5 is reflected on the reflection surface 4a even when the bulb 3 is not turned on. Dale is the glare, as shown in FIG. 6 (a), since the reflecting surface 4a formed on the reflector 4 is multistage, the reflection area light beam from the cap 5 by the stepped portion is reflected E1 And a dark area E2 that is not reflected.

[0004] Therefore, when viewed lamp body 6 from the front, as shown in FIG. 6 (B), the reflection area E being reflected
1 appears to be the reflecting surface 4a of the cap 5 is substantially the same color (amber), dark area E2 that is not reflected remains state of the reflecting surface 4a, i.e., visible silver color (hatched portion shown in FIG. 6 (B)).

The dark area E2 in which the light beam from the cap 5 is not reflected is based on the stepped shape of the reflector 4, but its position is shifted or lost depending on the angle at which the lamp body 6 is viewed. 3 is not dark in the sense that the light beam emitted from 3 is not reflected at all (hereinafter the same definition is used).

In this manner, since the dark area E 2 is located only on the side of the cap 5, the dark area E 2 has an amber color over a wide range of the cap 5 located substantially at the center of the lamp body 6. As a result, the presence of the cap 5 becomes apparent, and there is a problem that the appearance of the entire lamp body 6 is impaired.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a vehicular lamp that can make it difficult to recognize the presence of a cap and can improve the appearance.

[0008]

In order to achieve the object, according to the first aspect of the present invention, a lens is mounted on a front opening of a housing, a valve is mounted on the housing, and an inner wall surface of the housing is provided. In a vehicle lamp provided with a reflector having a multi-stage reflecting surface and a colored transparent cap for covering the bulb, the reflector is located between the cap and the lens and covers the front of the cap.
Provide a colorless transparent or white transparent inner lens
Further, the gist is that the inner lens is provided with a plurality of strip-shaped reflecting portions that apparently divide the cap along a ridgeline based on a step of the reflecting surface.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of a vehicular lamp according to the present invention will be described with reference to the drawings as applied to a turn signal lamp for a rear combination lamp.

(First Embodiment) FIGS. 1 and 2 show a first embodiment of a vehicular lamp according to the present invention. In FIG. 1, a vehicle lamp 10 shown in a horizontal section includes a housing 11, a lens 12 mounted on a front opening 11a of the housing 11,
Valve 13 mounted on housing 11, housing 1
1, a reflector 14 held on the housing 11 at the inner wall surface 11b side, a colored transparent (for example, amber) cap 15 mounted on the reflector 14 so as to cover the valve 13, and the lens 12 and the cap 15. An inner lens 16 is provided between them.

The reflector 14 is formed with a multi-stage reflecting surface 14a having ridge lines R extending in the vertical direction of the vehicle body. The color of the cap 15 is reflected on the reflection surface 14a even when the bulb 13 is not turned on. Also, this reflection is as shown in FIG.
Since the reflection surface 14a has multiple steps, the step portion forms a reflection area E1 where the light flux from the cap 15 is reflected and a dark area E2 where the light flux is not reflected.

Incidentally, the dark area E2 is provided with the vehicular lamp 10.
The reflection area E1 and the dark area E2 are essentially alternately adjacent to each other in the width direction of the vehicle body and extend in the vertical direction of the vehicle body. It has become.

The inner lens 16 is formed of a colorless or white transparent resin lens or the like.
Is held by any of the housing 11, the lens 12, the reflector 14, and the cap 15 so as to cover the front of the camera. As shown in FIG. 2 (A), transmitting portions 16a and 16 for transmitting the light flux from the cap 15 as it is (see arrow A) are provided on the surface of the inner lens 16 facing the cap 15.
and reflects the light flux from the lens 12 side (see arrow B)
Are alternately adjacent to each other in the vehicle width direction, and are formed in a belt shape extending along the vehicle vertical direction.

Are set so as to have substantially the same width E1 'as the reflection area E1 of the reflection surface 14a, and the reflection portions 16b, 16b are set to have substantially the same width as the dark area E2 of the reflection surface 14a. It is set to have E2 '. The reflecting portions 16b, 16b...
A plurality of pseudo dark means for apparently dividing the cap 15 along the vertical direction of the vehicle body when apparently appearing white when reflecting the light beam from the side. Becomes

The widths E1 'and E2' are
Area E1 and dark area E located near
2 based on the width. That is, the reflection surface 14a is designed according to the installation position and shape of the lamp body 15, and the width of the reflection area E1 and the width of the dark area E2 are not always uniform, so that the reflection surface 14a is set so as not to cause an unnatural appearance. Is done.

When the vehicle lamp 10 having such a configuration is viewed from the front, as shown in FIG. 2B, the reflection area E1 where the cap 15 is reflected is substantially the same color (amber color) as the cap 15. The dark area E2 which is visible on the surface 14a and is not reflected remains in the state of the reflecting surface 14a, that is, looks like silver, the cap 15 is transmitted from the transmissive portion 16a, and the light beam which is white due to its optical characteristics is transmitted from the reflective portion 16b. In comparison, the amber color and the silver color or a similar white color (both hatched portions shown in FIG. 2B) are alternately adjacent to each other, so that the presence of the cap 15 can be difficult to understand, and the appearance can be improved. Is improved and the striped vehicle lighting device 10 without a sense of incongruity is obtained.

Although the vehicle lighting device 10 shown in the figure has been described as a turn signal lamp for a rear combination lamp which is relatively flat in the vehicle vertical direction, it has a height in the vehicle vertical direction, Even in the case where a part of the reflector 14 exists, a pseudo dark area can be set by providing the inner lens 16 over the entire width of the reflector 14 in the vehicle vertical direction.

The inner lens 16 of the first embodiment has a concave reflecting portion 16b. However, as shown in FIG. 3, transmitting portions 26a, 26a.
b, 26b... are formed alternately.
4A and 4B, the same operation and effect as in the first embodiment can be obtained. 3 and 4, the same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof will be omitted.
