Description
Technical field
The present invention relates to automobile lamp field, more particularly to one kind is vertebration novel and uses Slit light lens
The total reflection prism system group of group.
Background technology
Optical system includes light source, colimated light system, full reflected system, scattering system.Generally, for automobile lamp,
Both needing the car light for designing can strictly meet laws and regulations requirement, again good appearance, generous.Automobile lamp space is increasingly
Compact, the illumination performance to automobile lamp proposes more requirements, wherein just the uniformity and uniformity of bag expansion brightness are asked
Topic.And while LED lamp is designed, it is considered however that the placement of electronic system LED light source and the Cost Design of pcb board,
Plurality of LEDs more to be taken into account as in the case of signal lamp, uniformity problems are lighted.Current automobile lamp, it is impossible to take into account above-mentioned
Problem, the uniformity and uniformity of brightness are not enough.Therefore, automobile lamp brightness uniformity and uniformity are solved not enough
Problem is just particularly important.
The content of the invention
It is vertebration novel it is an object of the invention to provide one kind and use for the problem that above-mentioned prior art is present
The total reflection prism system group of Slit light lens groups, using LED light source, by the collimation lens for constructing, light source is sent
The light of all angles come fully is transmitted to fully reflecting surface, and in the middle of fully reflecting surface and exiting surface, setting 3 or 5 is specific
The hollow hole of shape, using total reflection effect, forms the total reflection of various angles, controls the exiting surface that reaches of uniform light, solution
Automobile lamp brightness uniformity of having determined and the not enough problem of uniformity.
The present invention provides a kind of total reflection prism system group, including lamp housing, and the lamp housing is internally provided with LED light source, institute
State LED light source both sides and be provided with colimated light system, the LED light source rear portion is provided with total reflection minute surface, and the LED light source front sets
Hollow hole is equipped with, the hollow hole front is provided with exiting surface, by being totally reflected minute surface and hollow hole, using total reflection effect,
The total reflection of various angles is formed, control uniform light abreast reaches exiting surface.
Further improvement is that：Scattering decorative pattern is provided with the exiting surface.
Further improvement is that：The hollow hole is distributed between total reflection curved surface and exiting surface.
Further improvement is that：The hollow hole front is provided with light adjustment device, by light adjustment device to light
Line is adjusted.
After the light of all angles that LED light source sends incides collimation lens, the light in all directions is converted into a certain
The optical transport of a little specific directions is on total reflection curved surface.
The total reflection curved surface is one group of fully reflecting surface just to exiting surface, using total reflection effect, will be perpendicular to outgoing
The light of light direction is converted into the parallel rays towards exiting surface direction.
The hollow hole of given shape, is distributed in the middle of total reflection curved surface and exiting surface, using total reflection effect, will be towards going out
The uniform light exiting parallel in smooth surface direction.
The beneficial effects of the invention are as follows：By using LED light source, collimation lens, fully reflecting surface is combined, diffusion decorative pattern is additional
The airport of 3 or 5 given shapes is combined, and is set by carrying out cleverly optical texture respectively to various fully reflecting surfaces
Meter, makes Electronic Design cost-effective, while having the LED car lamp optical system of the bright uniformity of higher point.

Minute surface 4, the front of the LED light source 2 is provided with hollow hole 5, and the front of the hollow hole 5 is provided with exiting surface 6, by completely reflecting mirror
Face 4 and hollow hole 5, using total reflection effect, form the total reflection of various angles, and control uniform light abreast reaches exiting surface
6.Scattering decorative pattern 7 is provided with the exiting surface 6.The hollow hole 5 is distributed between total reflection curved surface 4 and exiting surface 6.It is described
The front of hollow hole 5 is provided with light adjustment device 8, and light is adjusted by light adjustment device 8.By using LED light
Source 2, collimation lens, combines fully reflecting surface, and the airport for spreading the additional given shape of decorative pattern is combined, and is all-trans by various
Penetrate face carries out cleverly optical texture design respectively, makes Electronic Design cost-effective, while having the LED of the bright uniformity of higher point
Car light optical system.
