Description
Technical field
The present invention relates to a kind of car lights, are a kind of car light optical textures changing light source diffusion angle specifically.
Background technology
Automotive lighting is always the important guarantee of driving at night safety safely.One good car light should have high-quality
Photometric standards.But each light source has an illumination range that it is limited, how using other factors come to improve road illumination be car light
Research and development need one of the direction opened up.
The material of traditional light transmission and diffusing light is all transparent or milky white glass or plastics, and light is sent out when passing through them
Go out refraction (transparent material) or diffusion (diffusive transmissive material), they are controlled afterwards by plain film or prismatic lens (only to transparent material)
The trend of light processed, to achieve the purpose that change light source light distribution.But the ability or effect of control light component are relatively low, by rib
Angle size, the reflection of material surface and refractive index value limitation, the deviation angle of light has the upper limit, inefficient.Cause
It needs to design complicated structure figure in this lens structure, required light type could be obtained.
Invention content
The technical problem to be solved in the invention is：It needs to design complicated structure flower in existing lens structure
Line could obtain required light type.Therefore more complicated in structure, and the difficulty of light type design forming is larger.
The present invention takes following technical scheme：
It is a kind of to have the car light optical texture for changing light source diffusion angle, including at least one light source, compound lens；Institute
It includes LSD material layers, adhesive phase, light distribution mirror layer to state compound lens；The compound lens it is equal with light-emitting surface into smooth surface
For the structure of continuously smooth, the light source is arranged in the side of the lens, and the lens other side has at least one
Light type.
Further, when the LSD material layers form film piece, there can be 0.2-90 ° of different angle above.
Further, the compound lens other side can have multiple light diffusion zones (2-1,2-2,2-3).
Further, the car light optical texture is used for signalling light for vehicle.
Further, the outgoing light type is the ellipse according to actual needs, rectangular etc..
The beneficial effects of the present invention are：
1) LSD is a kind of thin slice made of makrolon or polyester material, is used on one side made of holographic technology
The decorative pattern or texture emerged is protruded, is got using being replicated in holographic recording disk, surface looks like some random mixed and disorderly flowers
Sample, like many lenticules have been polymerize, to be accurately controlled along the light distribution on vertically and horizontally axis.
2) compound lens transmitance is up to 92%, and the uniformity of transmitted light is fine.
3) simplify the structure of lens, lens structure design difficulty substantially reduces.
4) complicated light type design can be carried out as needed so that light type is rich in diversity.

Fig. 2 is the light type figure of Fig. 1.
Fig. 3 is the front view of compound lens and transmissive viewing screen in the embodiment of the present invention one.
Fig. 4 is the light type figure of Fig. 3.
Fig. 5 is the refraction schematic diagram for light path using compound lens in the embodiment of the present invention two.
In figure, 1. light sources, 2. compound lens, 3. transmissive viewing screens.
Specific implementation mode
Present invention will be further explained below with reference to the attached drawings and specific examples.
In car light, light that LED light source is sent out can pass through the outer with penetrating of car light after the reflection of relevant optical device
Go out, traditional is outer with using plastic materials such as PC, PMMA, and refractive index is relatively low, inefficient.LSD materials are used in the application
The outer of matter is matched, and the diffusion angle of light is controlled by the way that the angle of LSD form film on pieces is targetedly arranged, to make up road
The bad situation of face illumination.
Embodiment one：
Referring to Fig. 3-4, a kind of have a car light optical texture for changing light source diffusion angle, including at least one light source, multiple
Close lens；The compound lens includes LSD material layers, adhesive phase, light distribution mirror layer；The compound lens into smooth surface
It is the structure of continuously smooth with light-emitting surface, the light source is arranged in the side of the lens, the lens other side tool
There is at least one light type.
In this embodiment, when the LSD material layers form film piece, there can be 0.2-90 ° of different angle above.Finally
The light type of formation is the non-primary light type such as oval or rectangular, as shown in Figure 4.Depending on the diffusion of angular dimension on demand, to
The characteristic for realizing orientation diffusion or compression light source changes shape and the direction of light distribution.
In this embodiment, the car light optical texture is used for signalling light for vehicle.
LSD is bonded by adhesive and common lens, and also including other processing methods makes the two merge, but on condition that not
Change the diffusion of LSD materials and compresses the characteristic of light source optical path.
Embodiment two：
It is in place of the present embodiment and the difference of embodiment one：Compound lens into smooth surface be directional light, compound light distribution
The mirror other side can have multiple light diffusion zones (2-1,2-2,2-3).
LSD of the present invention is a kind of thin slice made of makrolon or polyester material, uses holographic technology system on one side
At the protrusion decorative pattern or texture that emerge, got using being replicated in holographic recording disk, it is random miscellaneous that surface looks like some
Sample is recklessly spent, like many lenticules have been polymerize, to be accurately controlled along the light distribution on vertically and horizontally axis；It is compound to match
Light microscopic transmitance is up to 92%, and the uniformity of transmitted light is fine；Simplify the structure of lens, lens structure design is difficult
Degree substantially reduces；Complicated light type design can be carried out as needed so that light type is rich in diversity.
It is the preferred embodiment of the present invention above, those of ordinary skill in the art can also carry out various changes on this basis
It changes or improves, under the premise of not departing from the present invention total design, these transformation or improve should all belong to that the present invention claims guarantors
Within the scope of shield.
