Description

A kind of arrangement of car light heavy wall light guide
Technical field
It the utility model is related to automobile lamp, and in particular to the arrangement of the heavy wall light guide of automobile position lamp and steering indicating light Form.
Background technology
In the modeling scheme of current automobile lamp, two kinds of functions of light fixture are integrated in same production by more and more designers Realized in product, and very high requirement is proposed to the uniformity of light-emitting area, to meet this requirement, with dual-colored LED light source Heavy wall light guide is the most frequently used structure type.
Tradition carries the heavy wall light guide arrangement of dual-colored LED light source, generally there is following two schemes:
Scheme one:As shown in figure 1, yellow LED light source 2, the arranged for interval of White LED light source 3 behind heavy wall light guide 1, are sent out The light gone out is emitted directly toward in heavy wall light guide 1, and is transmitted by heavy wall light guide 1, real respectively under different logical conditions Turn now to or position lamp function.
Scheme two:As shown in Fig. 2 yellow LED light source 2, White LED light source 3 are arranged vertically on behind light guide 1 in Z-direction, light Line is emitted directly toward in heavy wall light guide 1, and is transmitted by heavy wall light guide 1, is realized and is turned to respectively under different logical conditions Or position lamp function.
For tradition carry dual-colored LED light source heavy wall light guide arrangement, both the above scheme all Shortcomings, mainly It is as follows:
Scheme one:As shown in figure 1, yellow LED light source 2, the arranged for interval of White LED light source 3, same color LED intervals compared with Greatly, when lighting, transparent surface is uneven, dark space be present.
Scheme two:As shown in figure 3, because yellow LED light source 2, White LED light source 3 are arranged vertically in Z-direction, therefore in Z-direction Larger space is needed, the thickness of rear wall light guide needs to be multiplied, and to light fixture in Z-direction space requirement increase, therefore has to moulding Considerable restraint.
The content of the invention
The heavy wall light guide arrangement of dual-colored LED light source is carried for tradition, is primarily present two aspect problems:Light-emitting area is not Uniformly, dark space when lighting be present;Z-direction space requirement is larger, limits the shape-designing of light fixture early stage.
The utility model proposes a kind of arrangement of car light heavy wall light guide, is asked with solving two above-mentioned simultaneously Topic, i.e., under the premise of meeting that light-emitting area is uniform, reduce the size requirement of Z-direction.
Technical solution of the present utility model is as follows:
A kind of arrangement of car light heavy wall light guide, including LED light source and heavy wall light guide, the LED light source are arranged in thickness Wall light guide lower rear, reverberation bowl is disposed with heavy wall light guide rear, the light that LED light source is sent after reverberation bowl reflects, Inject in heavy wall light guide, and transmitted by heavy wall light guide.
Further, the LED light source includes at least two colors, there is provided the car light to difference in functionality uses.
Specifically, the LED light source includes yellow LED light source, White LED light source, yellow LED light source and White LED light Source horizontal Tile is continuously arranged in the lower rear of heavy wall light guide 1.
Specifically, the car light is the integrated of automobile position lamp and steering indicating light.
Heavy wall light guide arrangement in the utility model, yellow LED light source and White LED light source are at heavy wall light guide rear portion Lower section is continuously arranged, can ensure the uniformity of light-emitting area when lighting;Yellow LED light source and White LED light source are arranged in simultaneously The lower rear of heavy wall light guide, the space requirement of Z-direction can be reduced;And by speculum in advance to yellow LED light source and white The light of color LED light source is injected in reverberation bowl 4 again after carrying out luminous intensity distribution, is made light mixing abundant, be ensure again that the uniform of light-emitting area Property.
As can be seen here, the utility model can improve the uniformity of light-emitting area, reduce Z-direction bulk, make the point of light fixture It is bright better attractive in appearance and provide more flexibilities for light fitting shape.

In figure:1- heavy walls light guide, 2- yellow LED light sources, 3- White LED light sources, 4- reverberation bowls.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description:
The arrangement of heavy wall light guide of the present utility model mainly solves that light-emitting area in Fig. 1 schemes is uneven and Fig. 2 schemes Middle Z-direction size requires larger problem, and is realized by a kind of arrangement.
Reference picture 5, the utility model are the heavy wall light guide cloth provided for automobile position lamp and steering indicating light integrated morphology product Structure is put, its structure is:Yellow LED light source 2, the horizontal Tile of White LED light source 3 are continuously arranged under the rear portion of heavy wall light guide 1 Side;Reverberation bowl 4 is arranged in behind heavy wall light guide;The light that yellow LED light source 2, White LED light source 3 are sent is anti-by reverberation bowl 4 After penetrating, inject in heavy wall light guide 1, and transmitted by heavy wall light guide 1.
The utility model heavy wall light guide arrangement, can not only reduce the space of heavy wall light guide Z-direction, be carried to light fitting shape For bigger space;Simultaneously because the continuously reflection of arrangement and reverberation bowl 4 to light of yellow LED light source 2, White LED light source 3, The uniformity of light-emitting area can also will be improved, ensures aesthetic during lighting.
