Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a vehicular lamp that reduces and prevents shadows caused by the stem of a bulb.

[Conventional technology]

Cars have headlights, direction indicators, taillights,
Recently, a so-called combination lamp is equipped with many lighting devices such as a reversing light, and instead of configuring each lighting device individually, it integrates multiple lighting devices as shown in Figures 3 and 4. is also used. That is, this light fixture 1 is one in which a direction indicator light 2, a tail light 3, a brake light 4, and a reversing light 5 are integrally combined. A lamp body 13 having lamp chambers 9, 10, 11, and 12 and whose inner surface constitutes a reflecting mirror R by vapor deposition of Al, etc., is provided with a bulb 14, 15, 16 and 17 are inserted into the lamp body 13 from the rear side. In addition, a back cover 23 that integrally has sockets 20, 21, 22 for holding the bases of the bulbs 15, 16, 17 is removably attached to the back of the lamp body 13 at the portion corresponding to the lamp chambers 10, 11, 12. It is being
The front lens 24 of the direction indicator light 2 is colored yellow (or amber), and the tail light 3 and brake light 4
The front lenses 25 and 26 of the vehicle are colored yellow, and the front lens 27 of the reversing light 27 is colored white. And these front lenses 24, 2
5, 26, 27 are usually integrally joined by forming by a conventionally well-known multi-color molding method, and the joints 28, 29, 30 are held by the partition wall 6 and shades 7, 8. has been done. Note 3
Reference numeral 1 denotes a retroreflector that reflects light from the rear in the same direction as its incident direction.

[The problem that the invention attempts to solve]

By the way, when the bulbs 14, 15, 16, and 17 are lit, the light emitted from the filament 32 extends in almost all directions, but the light only gets in the way in the direction where the pair of stems 33 that support the filament 32 are located. There was a problem that shadows were created and the appearance of the lighting equipment was poor.

That is, in the lamp having the structure shown in FIG. 3, for example, when the bulbs 15 and 17 are turned on, the shadow of the stem 33 appears in the ranges A and B indicated by broken lines in FIG. Although it is not visible from the front of the lamp as much as possible, the shadow of area A appears as thin fan-shaped shadows 35 and 36 on the front lenses 25 and 27 when viewed from the front.

[Means for solving problems]

The vehicle lamp according to the present invention was made to solve the above-mentioned problems, and includes a bulb whose filament is held by a pair of valve stems,
A reflecting mirror and a reflecting section are arranged across the bulb in a direction in which the valve stems are arranged side by side, and the reflecting section reflects the light from the bulb toward the reflecting mirror, and the reflecting mirror reflects the light from the bulb toward the reflecting mirror. It is designed to reflect the light and the reflected light from the reflecting part forward.

[Effect]

In the present invention, since the shade is provided with a reflective portion, the shadow caused by the bulb stem can be canceled out by the light reflected by the reflective surface.

〔Example〕

Hereinafter, the present invention will be described in detail based on embodiments shown in the drawings.

FIG. 1 is a sectional view showing an embodiment of the vehicle lamp according to the present invention applied to a combination lamp, and FIG. 2 is a front view of the lamp. In addition,
In the figure, the same components and parts as in FIGS. 3 and 4 are designated by the same reference numerals, and their explanations will be omitted. In these figures, the present embodiment has a mirror 40 as a reflecting section on the surface of the shade 7 on the lamp chamber 10 side.
This mirror 40 reflects the light directed toward the shade 7 out of the light emitted from the bulb 15, and guides it to the side of the bulb 15 opposite to the side where the mirror 40 is located. Further, the shade 8 that partitions the lamp chamber 11 and the lamp chamber 12 is formed integrally with the rear wall 11a of the lamp chamber 11 and in a curved or linear shape so as to substantially match the curvature of the wall 11a, and In other words, the surface facing the valve 17 is made of Al.
The reflective portion 41 is formed by applying a vapor-colored or white paint. The bulb 17 is arranged obliquely so that its optical axis is substantially parallel to the reflecting section 41. Of the light emitted from the bulb 17, the light directed toward the shade 8 is reflected by the reflecting section 41 and guided to the reflecting mirror R side of the bulb 17, which is opposite to the side where the reflecting section 41 is located. And this reflector R
reflected forward.

Note that the other configurations are exactly the same as the conventional lamp shown in FIGS. 3 and 4.

Thus, in the combination lamp having such a configuration, out of the light emitted from the bulbs 15 and 17, the light directed toward the shades 7 and 8 is reflected by the mirror 40 and the reflecting surface 41, and the mirrors of these bulbs 15 and 17 40, the area A generated by the stem 33 is guided to the reflecting mirror R side opposite to the side where the reflecting surface 41 is located.
can almost completely cancel out the shadow.

On the other hand, the shadows formed behind the shades 7 and 8, that is, the shadows in area B in FIG. 3, are blocked by the shades 7 and 8 and cannot be seen from the front.

In addition, although the above embodiment has been described for the case where it is applied to a combination lamp, the present invention is not limited to this in any way, but can be applied to any single lamp that has a shade and produces a shadow due to a bubble stem. May you have what you get.

[Effect of idea]

As explained above, the vehicular lamp according to the present invention directs the light from the bulb by the reflecting part disposed on one side of the bulb toward the reflecting mirror disposed on the opposite side of the reflecting part and the bulb. The structure is configured so that the light from the bulb and the reflected light from the reflecting part are reflected forward by the reflecting mirror, so the shadow of the valve stem is canceled by the light reflected by the reflecting part, so the structure is simplified. The appearance and visibility of the lamp can be improved.
