Description
Technical field
The present invention relates to automobile signal light field of optical systems more particularly to a kind of light guide pattern structures.
Background technique
The fast development of automobile industry, the car light accessory important as contour of the vehicle moulding are also weight in vehicle modeling
Want role.Vehicle client to the appearance of car light, also increasingly pay attention to by the size of whole compact and light-emitting area.Light guide is then
Realize popular technology at present to realize various compact moulding.
Each light guide tooth of the Light-guiding optics patterned surface is formed by two planes in the case where the prior art, makes light
Line follows total reflection law in communication process, however styling trends currently on the market are no longer pervious long light guides, very much
Moulding is to be combined to realize signal lamp function by more short light guides, the drop of whole optical efficiency caused by being reduced due to the length of light guide
It is low to be made up or the increase of LED particle number sometimes for by the input for increasing light source, and this inevitably results in whole lamp cost
Increase.Therefore, a kind of efficient light guide light distribution decorative pattern is designed, the optical efficiency for improving light guide is just particularly important
?.
Summary of the invention
To solve the above problems, the object of the present invention is to provide a kind of light guide pattern structure, by several light guide decorative pattern arcs
The optical patterns face in face and several light guide decorative pattern planes composition inner surface side, one in the light guide patterned surface of each light guide tooth
Face is cambered surface, since the light guide tooth patterned surface of side in the present invention is cambered surface, has this feature of aggregation feature to light using cambered surface,
The light that light guide goes out more is converged in into the search coverage of laws and regulations requirement, while guaranteeing to constitute another face of each light guide tooth
For plane, to improve the efficiency of whole light guide.
The present invention provides a kind of light guide pattern structure, including the Light-guiding optics patterned surface of light guide inner surface side is arranged in and sets
The outer surface in outer surface side is set, the Light-guiding optics patterned surface is by light guide patterned surface cambered surface and light guide patterned surface
The quantity of plane composition, the light guide patterned surface cambered surface and light guide decorative pattern facial plane is at least one, wants according to regulation and design
It asks progress quantity to determine, and light guide patterned surface cambered surface and light guide decorative pattern facial plane are staggered, forms Light-guiding optics patterned surface.
Further improvement lies in that: light is totally reflected after being incident in light guide, i.e., when light enters air by lens, enters
When firing angle is greater than critical angle, light can be totally reflected, and change the light direction of propagation, be emitted towards outer surface, wherein critical
Angle is arcsin (n2/n1), and wherein n2 is the refractive index of light guide, and n1 is the refractive index of air, when light is propagated in light guide,
After encountering Light-guiding optics patterned surface, the Light-guiding optics patterned surface changes light refraction angle, and refraction angle is less than the angle of total reflection
Degree, light are emitted from outer surface.
Further improvement lies in that: the light guide is made of polymethyl methacrylate or makrolon material.
The beneficial effects of the present invention are: moulding and structure based on entire light guide are constant, simply by the optics to light guide
One face of light guide tooth is changed to cambered surface from plane by the optimization of decorative pattern part, and the convergence of light is acted on using cambered surface, thus
Promote the optical efficiency of whole light guide.And the original uniformity of light guide is kept not to be affected.
Detailed description of the invention
Fig. 1 is optical system structure schematic diagram of the invention.
Fig. 2 is Light-guiding optics decorative pattern partial schematic diagram of the invention.
Wherein: 1- Light-guiding optics patterned surface, 2- outer surface, 3- light guide patterned surface cambered surface, 4- light guide decorative pattern facial plane.
Specific embodiment
In order to deepen the understanding of the present invention, below in conjunction with embodiment, the present invention is described in further detail, this implementation
Example for explaining only the invention, is not intended to limit the scope of the present invention..
As shown in Figure 1, 2, a kind of light guide pattern structure, the light including light guide inner surface side is arranged in are present embodiments provided
Leaded light learns patterned surface 1 and the outer surface 2 that outer surface side is arranged in, and the Light-guiding optics patterned surface 1 is spent by light guide
Line face cambered surface 3 and light guide decorative pattern facial plane 4 form, and light guide patterned surface cambered surface 3 and light guide decorative pattern facial plane 4 are staggered, shape
At Light-guiding optics patterned surface 1.Light is totally reflected after being incident in light guide, i.e., when light enters air by lens, incidence angle
When greater than critical angle, light can be totally reflected, and change the light direction of propagation, be emitted towards outer surface 2, and wherein critical angle is
Arcsin (n2/n1), wherein n2 is the refractive index of light guide, and n1 is the refractive index of air, when light is propagated in light guide, is encountered
After Light-guiding optics patterned surface 1, the Light-guiding optics patterned surface 1 changes light refraction angle, and refraction angle is less than total reflection angle,
Light is emitted from outer surface 2.The light guide is made of polymethyl methacrylate materials.Moulding based on entire light guide and
Structure is constant, and by the optimization of the optical patterns part to light guide, a face of light guide tooth is changed to cambered surface from plane, utilizes
Cambered surface acts on the convergence of light, the light that light guide goes out more is converged in the search coverage of laws and regulations requirement, to be promoted whole
The optical efficiency of root light guide.And the original uniformity of light guide is kept not to be affected.
