Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicular lamp used for a vehicle such as an automobile, and more particularly to a vehicular lamp in which the number of components is reduced in a composite lamp in which a plurality of lamps are integrated.

[0002]

2. Description of the Related Art In a vehicular lamp such as an automobile, in particular, in a rear combination lamp in which a plurality of lamps provided at the rear of an automobile are combined, a reflector, a bulb (bulb) and a lens are provided for each of the plurality of lamps. There is a need. In recent years, there has been proposed a lamp in which an inner lens is provided for each of a plurality of lamps, and a single outer lens is provided for the combined lamp as a whole to enhance the design effect. Therefore, in this type of lamp in recent years, there is a problem in that the number of constituent parts increases and the cost of the lamp increases. For this reason, an attempt has been made to reduce the number of components of the entire lamp by sharing components among a plurality of lamps to be combined. For example,
As one attempt, a structure in which reflectors of a plurality of lamps arranged adjacent to each other are integrated has been considered, and it is possible to reduce the number of reflectors of the entire lamp. As another attempt, a structure in which a reflector of one lamp and a lens of an adjacent lamp are integrated can be considered. That is, the reflector and the lens are integrally formed of a light-transmitting resin, and a surface treatment is performed so that a region corresponding to the reflector becomes a reflection surface. This makes it possible to reduce the number of components by integrating the reflector and the lens.

[0003]

In such a conventional lamp, when the outer lens attached to the front opening of the lamp body is formed as a transparent lens, a joint between reflectors of adjacent lamps, The joint between the reflector and the lens is exposed to the outside through the outer lens, which causes a reduction in the appearance of the lamp. Further, among the above-mentioned conventional lamps, when a lens formed integrally with the latter reflector is formed as an outer lens, a lens formed separately is disposed on the front surface of the lamp formed by the reflector, and It is necessary to join this lens and the lens integrally formed with the reflector at the boundary, and the boundary of this joint is exposed, which is a factor that degrades the appearance of the lamp. In order to hide such a joint between the reflector and the lens between adjacent lamps, a dummy reflector called an extension is arranged. The effect of reducing the score will be lost.

An object of the present invention is to provide a vehicular lamp in which the appearance of the lamp is improved while the number of components of the lamp is reduced.

[0005]

In this embodiment, although not shown in the drawing, a plurality of lens steps vertically arranged in the upper and lower inner lenses 11 and 13 are formed in a state extending in the horizontal direction.

In a state where the reflector / inner lens complex 24 is mounted in the lamp body 1,
The front edge of the lower surface 21c of the upper reflector 21 and the front edge of the upper surface 23c of the lower reflector 23 are arranged at positions on the back side of the central reflector 22, respectively. From the side, the front edge of the lower surface 21c of the upper reflector 21 and the front edge of the upper surface 23c of the lower reflector 23 are not exposed through the inner lenses 11 and 13, respectively.
Further, a boundary region between the central reflector 22 and the upper and lower inner lenses 11 and 12 has a plurality of band-shaped cross-sections extending in a horizontal direction, and is formed in a step-like shape. Also, as shown in FIG. 2, a reflection film M which is the same as the reflection film M constituting the reflection surface 22b of the central reflector 22 is formed, and is formed as a dummy reflector, that is, an extension part EXT. In the upper turn signal lamp TSL, the upper edge of the upper inner lens 11 abuts on the front edge of the upper surface 21b of the upper reflector 21, and in the lower backup lamp BUL, the lower inner lens 13 is the lower reflector 2
3 is in contact with the front edge of the lower surface 23b.

In the central tail and stop lamp T & SL, an auxiliary lens 14 having a rectangular frame shape that is horizontally long when viewed from the front is disposed so as to surround the light bulb 3b, and a rear opening of the auxiliary lens 14 is provided. The edge portion 14a is supported in a state in which it is fitted in a horizontal groove 22c formed vertically spaced apart from the reflecting surface 22b of the central reflector 22. The auxiliary lens 14 is made of a red transparent resin, and the upper surface 14b and the lower surface 14c of the auxiliary lens 14 remain in a red transparent state. Also, the front opening 14d
The inner lens (hereinafter, referred to as a central inner lens 12) formed in a plate shape curved with red resin.
Are fitted and attached. Here, the lances 12a provided at a plurality of peripheral edges of the central inner lens 12 are engaged with the opening edge of the front opening 14d of the auxiliary lens 14. In this embodiment, a diffusion lens 16 is provided along the inner surface of the central inner lens 12. A retroreflection step is formed on a part of the central inner lens 12, and a retroreflection mirror 15 is formed. Also, here, the upper edge 14e and the lower edge 14f on the front side of the auxiliary lens 14 are respectively provided with the extension EXT provided in the central reflector 22 and each boundary area between the upper and lower inner lenses 11, 13, and the design.

A so-called transparent outer lens 2 which is white and transparent and has no lens steps formed thereon is disposed so as to cover the front side of the lamp body 3, and a front opening of the lamp body 1 is provided at a seal leg 2a provided on a peripheral portion thereof. It is fixed to the edge 1f by welding or the like.

In the rear combination lamp RCL having the above structure, the central reflector 22 of the tail & stop lamp T & SL and the turn signal lamp TSL at the upper part.
And the lower inner lens 13 of the lower backup lamp BUL
Since the inner lens complex 24 is integrally formed of a transparent resin, one reflector and two inner lenses can be configured as one component, and the number of components for configuring the rear combination lamp RCL is reduced. It becomes possible. The central reflector 22 and the upper and lower inner lenses 1 are also provided.
Since the extension parts EXT arranged at the respective boundaries of the reflectors 1 and 13 are also formed integrally with the reflector / inner lens complex 24, the number of parts can be reduced from this surface as well. In addition, the extension part EXT includes a boundary region between the upper reflector 21 and the central reflector 22 that may be exposed through the upper inner lens 11, and the lower inner lens 1.
Lower reflector 23 that may be exposed through 3
Since the boundary regions of the central reflector 22 and the central reflector 22 are covered, it is possible to prevent the appearance from being degraded by exposing these boundary portions.

Particularly, in the present embodiment, the upper reflector 2
The front edge of the lower surface 21c and the front edge of the upper surface 23c of the lower reflector 23 are located on the rear surface of the central reflector 22, respectively.
Even when the range of T, that is, the vertical dimension is designed to be small, it is possible to effectively prevent the front edges of the upper and lower reflectors 21 and 23 from being exposed. Further, since the cross section of the extension portion EXT is formed in a stepped shape, the extension portion EXT is conversely formed.
When the extension portion EXT is observed, a three-dimensional effect can be obtained even when the range of is widened, that is, when the vertical dimension is designed to be large, and the appearance can be improved from this point as well.

The central reflector 22 of the central tail & stop lamp T & SL has upper and lower inner lenses 11 and 13 integrally formed vertically. The tail & stop lamp T & SL has the following structure. Since the center inner lens 12 is supported by the auxiliary lens 14 in a region vertically separated from the inner lenses 11, 13, the upper and lower inner lenses 11, 13 and the center inner lens 12 are supported. There is no joint to join the lens 12. For this reason, even when the outer lens 2 is configured as a transparent lens, the appearance of each of the inner lenses 11, 12, 13 and each of the reflectors 21, 22, 23 does not deteriorate.

In the rear combination lamp RCL of the embodiment, a central inner lens 12 is disposed by an auxiliary lens 14 on the central tail and stop lamp T & SL so as to cover the light bulb 3b. A retroreflective mirror 15 is formed on a part of the front surface of the inner lens 12. Therefore, when the tail & stop lamp T & SL is turned on, a part of the light emitted from the electric bulb 3b is used for the upper surface 14b and the lower surface 14 of the auxiliary lens 14.
c and the reflection surface 22 of the central reflector 22
b, passes through the outer lens 2 and irradiates to the outside. At this time, since the upper surface 14b and the lower surface 14c of the auxiliary lens 14 are transparent, the central reflector 2
2 does not affect the reflection and irradiation of light. Another part of the light from the light bulb 3b is radiated to the outside through the central inner lens 12, so that this part is also brightly illuminated. Further, the upper edge portion 14e and the lower edge portion 14f of the front side of the auxiliary lens 14 each have a step-like cross-sectional shape similar in appearance to the extension portion EXT.
It is also possible to obtain the effect of unifying the design as a whole and improving the appearance.

Here, in the above-described embodiment, an example is shown in which three lamps are applied to a combined rear combination lamp, and the reflector of one lamp is formed integrally with the inner lenses of the two lamps on both sides thereof. However, the reflector of one lamp may be formed integrally with the inner lens of one adjacent lamp. Also, 2
In a lamp in which two lamps are combined, the reflector of one lamp and the inner lens of the other adjacent lamp may be integrally formed.

[0020]

As described above, according to the present invention, since the reflector of the first lamp of the plurality of lamps and the inner lens of the second lamp adjacent thereto are formed integrally, the lamp Can be reduced, especially the number of components for the extensions. In the boundary area between the integrated reflector and inner lens,
Since the extension part is formed by extending a part of the light reflecting surface constituting the reflector to a part of the second lamp, a joint part between the first lamp and the second lamp is hidden by the extension part. Can improve the appearance of the lamp. In this case, the reflector of the second lamp has a configuration in which the opening edge on the first lamp side is arranged at the rear position of the reflector of the first lamp, so that even when the extension portion is formed small. In addition, the opening edge of the reflector of the second lamp can be prevented from being exposed, and the external appearance of the lamp can be further improved. Also, the extension part
By adopting a configuration in which the cross-sectional shape is formed stepwise, even when the extension portion is formed large, a three-dimensional effect can be obtained and the appearance can be improved.
