Description
Technical field
The utility model is related to automobile lamp field, more particularly to one kind is vertebration novel and uses Slit light
The total reflection prism system group of lens group.
Background technology
Optical system includes light source, colimated light system, full reflected system, scattering system.Generally, for automobile lamp,
Both the car light designed is needed strictly to 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
The problem of, 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.
Utility model content
In view of the above-mentioned problems of the prior art, the purpose of this utility model is to provide a kind of vertebration novel and made
With the total reflection prism system group of Slit light lens groups, using LED/light source, by the collimation lens of construction, light source is sent out
The light of all angles out is fully transmitted to fully reflecting surface, in the middle of fully reflecting surface and exiting surface, sets 3 or 5 spies
The hollow hole of setting shape, using total reflection effect, forms the total reflection of various angles, control uniform light reaches exiting surface,
The problem of solving automobile lamp brightness uniformity and not enough uniformity.
The utility model provides a kind of total reflection prism system group, including lamp housing, and the lamp housing is internally provided with LED light
Source, the LED/light source both sides are provided with colimated light system, and the LED/light source rear portion is provided with total reflection minute surface, the LED/light source
Front is provided with front of hollow hole, the hollow hole and is provided with exiting surface, by being totally reflected minute surface and hollow hole, utilizes total reflection
Effect, forms the total reflection of various angles, and 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：Light adjustment device is provided with front of the hollow hole, by light adjustment device to light
Line is adjusted.
The light for all angles that LED/light source is sent is incided after collimation lens, and 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 utility model are：By using LED/light source, collimation lens, fully reflecting surface is combined, decorative pattern is spread
The airport of additional 3 or 5 given shapes is combined, by carrying out cleverly optical texture respectively to various fully reflecting surfaces
Design, makes Electronic Design cost-effective, while having the LED car lamp optical system of the bright uniformity of higher point.
