Description
Technical field
The utility model is related to automobile lamp field, more particularly to a kind of compact and luminous uniform double-colored car light light guide.
Background technology
With the development of automotive engineering, automobile lamp increasingly exquisitenessization, intellectuality.Each function of automobile lamp is also from most former
Begin independent cavity, evolves as shared light extraction cavity, and most commonly dazzle light is shared with position lamp.Additionally,
In the last few years, as the gradually maturation of LED technology, more car lights use LED as light source, each car light factory have devised far
The shared module car light of dipped beam.Headlight also occurs in that daytime running lamps are shared with position lamp, and taillight has engendered position lamp
With sharing for brake lamp.Space has all significantly been saved in these designs, and stronger technology sense is brought to automobile.Two kinds of functions
Car light it is relatively common, but they one it is common the characteristics of, that is, go out that light color is identical, they can be using same light source by electricity
The control realization light and shade change of output is flowed, so as to realize difference in functionality.But two kinds of color difference in functionalitys, then to the design band of car light
Bigger difficulty is carried out, the such car light of in the market is also more rarely seen.
Utility model content
For the problem that above-mentioned prior art is present, the purpose of this utility model is to provide a kind of compact and luminous uniform
Double-colored car light light guide, the shared car light light guide of turning function, daytime running lamps function and position lamp function realizes that yellow is turned to
Lamp and white daytime running lamps and position lamp are in same optronics.
The utility model provides a kind of double-colored car light light guide, including optical coupled face and reflecting surface, and the reflecting surface is set
At the back side in optical coupled face, longitudinal collimation plane is provided with by the optical coupled face, longitudinal collimation plane upper end is provided with
Transversal collimation face, longitudinal collimation plane right part is provided with equal smooth surface, and the optical coupled face lower section is provided with refractive power face.
Further improvement is that：The reflecting surface and incidence surface end face angle are 45 °, so that light is rolled over to travel direction
Turn.
Further improvement is that：The optical coupled face includes three sub- faces, and is incremented by apart from light inputting end interplanar distance, two ends
Sub- face opening amplitude is more than middle sub- face.
Further improvement is that：, at two source symmetric centers, another is unlimited for one focus in the optical coupled face
At a distance.
The light that light source sends is coupled into light guide by light guide head using the collimating structure of particular design, by three sub- faces
The optical coupled face for constituting carries out vertical direction collimation, and the light after once collimating is beaten again by the optical delivery of a segment distance
On the reflecting surface, 90 degree of light direction of transfer generation is turned back, or angle consistent with vehicle traveling direction is smaller.Set by special
The secondary collimation in horizontal light guide direction is realized when the transversal collimation face of meter and longitudinal collimation plane.
It should be noted that when light is by transversal collimation face and longitudinal collimation plane, light can have certain hair
Angle is dissipated, to increase even light effect.Even light is eventually passed through further to be homogenized in face of light and realize light distribution requirements.In this process
In, light by reflecting surface but not collimated light in part is beaten on refractive power face, realizes the deviation of light, it is to avoid from side observation
To hot spot.Light during due to by transversal collimation face and longitudinal collimation plane has been collimated, so even smooth surface is to laterally
The adjustment of collimation plane distance does not influence substantially on the uniformity of light guide.
The beneficial effects of the utility model are：It is simple and compact for structure, two kinds of photochromic car lights are realized in same light guide
Using, while cost-effective, save space, and bring more technology senses to car light.Lightguide length can be according to car light
Overall space requirement adjustment, more flexibilities are brought to car light global design.

Specific embodiment
In order to deepen to understanding of the present utility model, below in conjunction with embodiment, the utility model is described in further detail,
The embodiment is only used for explanation the utility model, does not constitute the restriction to the utility model protection domain.
As Figure 1-3, a kind of double-colored car light light guide, including optical coupled face 1 and reflecting surface 2 are present embodiments provided,
The reflecting surface 2 is arranged on the back side in optical coupled face 1, and longitudinal collimation plane 3 is provided with by the optical coupled face 1, described vertical
The upper end of collimation plane 3 is provided with transversal collimation face 4, the right part of longitudinal collimation plane 3 is provided with equal smooth surface 5, described optical coupled
The lower section of face 1 is provided with refractive power face 6.The reflecting surface 2 and incidence surface end face angle are 45 °, so that light is rolled over to travel direction
Turn.The optical coupled face 1 includes three sub- faces, and is incremented by apart from light inputting end interplanar distance, during two-terminal face opening amplitude is more than
Between sub- face., at two source symmetric centers, another is in unlimited distance for one focus in the optical coupled face 1.
Light guide head width 20mm, thickness is 6.2mm, and end face plane is 9mm apart from optical coupled face 8mm, A/F,
Meet two light sources to arrange simultaneously.Light guide edge surface is in 45 degree with light inputting end face apart from reflecting surface 15mm, reflecting surface.Light is by arc
Behind face, collimate in the horizontal direction.In order to allow the no collimated ray in part to cause light spot, increase refractive power face.Refractive power face carries one
Determine radian, strengthen dissipating effect.As automobile lamp light guide, it includes structure described in 11 Fig. 1.Increase on exiting surface
The grid array cambered surface of 2mmx2mm, there is provided even light and meet luminous intensity distribution.
