Abstract
The invention provides an automobile lamp light guide even in light emitting and free of light spots at the tail. The automobile lamp light guide comprises a light incidence plane, pattern-free areas, light guide rear surfaces, light guide front surfaces, light guide front surface patterns and light guide tail refraction face cylinder faces. The light incidence plane is arranged at the upper end of the light guide. The pattern-free areas are located at the lower portion of the light incidence plane. The light guide rear surfaces are located below the pattern-free areas. The light guide front surfaces are arranged on the front sides of the light guide rear surfaces. The light guide front surface patterns are arranged at the lower portions of the pattern-free areas. The light guide tail refraction face cylinder faces are arranged at the bottom of the light guide. Light emitting is even, the structure is simple and reasonable, and the stricter modeling requirement of a designer can be met. The blacking technology for the tail end of the light guide is avoided, the mixing distance of the light guide is shortened, and cost is saved.
Description
Technical field
The present invention relates to automobile lamp technical field, more particularly, to a kind of uniform and afterbody no hot spot car light that lights
Lead.
Background technology
Photoconduction is conducted to light using transparent strip column structure, by increasing decorative pattern on side by light line reflection
Out.Because light lead curve can flexibly change within the specific limits, increasing automobile lamp application light guide techniques are realized
Different moulding demands.But in order to ensure uniform in light emission, photoconduction can not be applied on all curves.On the one hand, for presence
The curve of little radius of curvature, can dark space in radius of curvature smaller part in photoconduction.This just brings limit to Automobile Design's teacher moulding
System.On the other hand, for the photoconduction that photoconduction direction and light direction angle are little, a problem being relatively difficult to balance is by light
Derive photoconduction, and control uniform in light emission.
Additionally, general photoconduction head needs the light Mixed Zone of relatively long distance, light effect with optimize decorative pattern.But this
Bring more problem to structural engineer.With the trend that car light is increasingly compact, the distance leaving photoconduction coupling for is shorter and shorter.
And afterbody needs to cover in relatively long distance in case ring, bright from flank angle observation afterbody appearance to avoid
Speckle.And in order to moulding is more attractive in appearance, designer requires to reduce this distance as far as possible.Therefore will be while will balance when designing photoconduction
Case ring coverage meets designer's modeling requirement again, or directly by photoconduction afterbody blacking, but blacking needs to increase by one
Step process, cost is also significantly increased.
Content of the invention
The problem existing for above-mentioned prior art, it is an object of the invention to provide a kind of luminous uniform and afterbody no hot spot
Car light photoconduction, the light that light source sends is coupled into photoconduction using planar structure by photoconduction head, mixed through no pattern zone
After conjunction, beat surface after photoconduction be gradually increased on patterned surface and the patterned surface of light leading surface traces on, in photoconduction curvature of curve half
The less position in footpath is provided with special decorative pattern to increase light-output light, and photoconduction afterbody adopts cambered surface to design, by light to diagonally forward
Refraction, it is to avoid observe afterbody from flank angle and speck occurs.
The present invention provide a kind of luminous uniformly and afterbody no hot spot car light photoconduction, including entering optical plane, no pattern zone, light
Lead rear surface, light leading surface traces, light leading surface traces decorative pattern and photoconduction afterbody refractive power face cylinder, described enter optical plane be arranged on photoconduction
Upper end, described no pattern zone is located at into optical plane bottom, and after described photoconduction, surface is located at no below pattern zone, described smooth leading
Surface is arranged on front side of surface after photoconduction, and described smooth leading surface traces decorative pattern is arranged on no pattern zone bottom, described photoconduction afterbody folding
Bright finish cylinder is arranged on photoconduction bottom.
Further improvement is that: stepped decorative pattern is provided with surface after described photoconduction.
Further improvement is that: described photoconduction afterbody is in that cambered surface designs, and light is reflected to diagonally forward.
Further improvement is that: on described smooth leading surface traces, be provided with light path detecting device.
The invention has the beneficial effects as follows: uniform in light emission, simple and reasonable, disclosure satisfy that harsher the making of more designer
Type demand.Avoid the blacking technique of photoconduction tail end, shortened photoconduction mixing distance, saved cost.

Specific embodiment
In order to deepen the understanding of the present invention, below in conjunction with embodiment, the invention will be further described, this embodiment
It is only used for explaining the present invention, do not constitute limiting the scope of the present invention.
As shown in Figure 1-2, present embodiments provide a kind of luminous uniformly and afterbody no hot spot car light photoconduction, including entering light
Surface 3, light leading surface traces 4, light leading surface traces decorative pattern 5 and photoconduction afterbody refractive power face cylinder 6 behind plane 1, no pattern zone 2, photoconduction,
Described enter optical plane 1 be arranged on the upper end of photoconduction, described no pattern zone 2 is located at into optical plane 1 bottom, surface 3 after described photoconduction
It is located at no below pattern zone 2, described smooth leading surface traces 4 are arranged on front side of surface 3 after photoconduction, and described smooth leading surface traces decorative pattern 5 sets
Put in no pattern zone 2 bottom, described photoconduction afterbody refractive power face cylinder 6 is arranged on photoconduction bottom.Arrange on surface 3 after described photoconduction
There is stepped decorative pattern.Described photoconduction afterbody is in that cambered surface designs, and light is reflected to diagonally forward.Arrange on described smooth leading surface traces 4
There is light path detecting device 7.Uniform in light emission, simple and reasonable, disclosure satisfy that the harsher moulding demand of more designer.Avoid
The blacking technique of photoconduction tail end, has shortened photoconduction mixing distance, has saved cost.
