Description
Technical field
The invention belongs to LED light leaded light technical field, and in particular to a kind of Novel LED light light guide structure.
Background technology
LED leaded lights technology has been used to all trades and professions at present, such as in automobile lamp industry, with the hair of auto industry
Exhibition, automobile becomes the indispensable traffic of human society and means of transport, and automobile and car light are inseparable, auto lamps
Tool is responsible for two kinds of functions of illumination and indication signal, it may be said that has automobile just to have car light.Hyundai Motor various shapes so that use
The experience requirements of car light are also increasingly improved at family.At present, full car carries LED car lamp to some high-end vehicles, and LED has volume
It is small, the advantages that energy conservation and environmental protection, therefore it is inevitable trend as vehicle lamp light source in future, LED.The LED of other industry is guide-lighting should
With equally meeting pay attention to day by day.
The light guide of lamp is the guide-lighting medium of LED light source, and the light that LED is sent comes out again after being reflected by light guide.Nowadays,
In many LED light, all there is the problem of guide-lighting uneven, light losing is larger；In addition traditional light guide structure uses light side
Enter and the back side carries the light conducting plate structure of site, diffuser plate and reflectance coating must also be set, and material configuration is more, and manufacture craft is multiple
Miscellaneous, volume is larger, low space utilization；In addition, also light-emitting surface is complex-shaped tooth on the guide-lighting block of some traditional LED light
Face, substandard products are relatively more in production, mainly the injection class defect in terms of appearance, weld bond, current mark, and deflated etc., presentation quality is poor,
Internal impurity also have impact on the uniformity of light extraction more.It is to be solved heavy that the light distribution design of light guide has become field technology personnel
Want problem.
The content of the invention
The purpose of the present invention is overcome defect existing in the prior art, there is provided a kind of effect that visually uniform light can be achieved
Fruit, light losing is few, improves light utilization；Material configuration is few, simple in structure, small volume, improves space profit
With rate；Easily manufactured without traditional zigzag structure, quality is good after shaping, and even photosensitiveness is good, optimizes light guide structure appearance
Novel LED light light guide structure.
The technical solution adopted by the present invention to solve the technical problems is：A kind of Novel LED light light guide structure, it includes
LED light source and guide-lighting block, guide-lighting block are equipped with import convex surface and fully reflecting surface, and LED light source is used towards import convex surface, fully reflecting surface
It is totally reflected in by the refracted light on import convex surface；Guide-lighting block is also evenly equipped with some condenser grooves on the reflection direction of fully reflecting surface,
Condenser groove includes optically focused convex surface and the receiving plane towards optically focused convex surface, the reflection of optically focused convex surface and receiving plane along fully reflecting surface
Set gradually in the positive direction of light；Put down equipped with light extraction end of the guide-lighting block in the positive direction of the reflection light of fully reflecting surface
Face, receiving plane are oppositely arranged with exit plane.
First, the light of LED light source injects import convex surface；After optically focused, light polymerize to less scope, and uniformly
It is incident upon fully reflecting surface；After total reflection, light injects optically focused convex surface, polymerize again and injects receiving plane, so through multiple poly-
After light groove optically focused, projected from exit plane uniform light.
For the present invention successively by an optically focused, reflection, several times after optically focused, uniform in light emission can be by light in longer biography
Output is, it can be achieved that light is uniform in light-guiding mechanism after scattering during broadcasting repeatedly is corrected and polymerize to a less scope
Propagate, so as to fulfill the uniform effect of vision, the light losing after multiple optically focused is few, effectively increases light utilization.This
Invention does not use traditional light guide structure, and employs new-type light guide structure, material of the invention only LED light source and leaded light
Block, material configuration is few, and simple in structure, small volume, effectively increases space availability ratio；Without traditional zigzag structure, manufacture
Convenient, quality is good after shaping, and even photosensitiveness is good, optimizes the appearance of light guide structure, greatly improves the degree of recognition of client.The present invention
For single led light guide module, multiple LED light guide modules arrays can be arranged to LED light, uniform in light emission, light is beautiful, and brightness is equal
In even and regular, daytime running lamps etc. are applicable to.The present invention can be used for the fields such as turn signal leaded light.
Preferably, the angle of reflection of fully reflecting surface is 45 °.
Further, guide-lighting block is moulding, and guide-lighting block injection molding is easy to process.
Further, condenser groove is the hollow slots on guide-lighting block, convenient to process.In addition, if condenser groove is groove-like, then
Light easily directly transmits and mistake from slot bottom, have impact on spotlight effect.The condenser groove of the present invention is the hollow slots on guide-lighting block, is polymerize
Light effects are more preferable, avoid scattering and disappearing for light.
Specifically, import convex surface and optically focused convex surface are arc-shaped, and optically focused can be carried out as planoconvex spotlight.
Preferably, medium is air in condenser groove, and light laser propagation effect is good, is not required to additional seal other media, embodiment party
Just.
Specifically, the center on LED light source alignment import convex surface, directional light are injected, then spotlight effect is more preferable；It is if oblique
Inject, then easily refraction is lost a part of.
Specifically, angle is 0 ° -75 ° between receiving plane and exit plane.When being pressed from both sides between receiving plane and exit plane
Angle be 0 ° when, then receiving plane is parallel with exit plane, then multiple light guide structure modules of the invention can array be assembled into light extraction
Plane is arranged with parallel LED lamp with LED light；When angle is 0 ° -75 ° (being free of 0 °) between receiving plane and exit plane
When, then suitable for special inclination LED light.The present invention can be used for the fields such as turn signal leaded light.
A kind of beneficial effect of Novel LED light light guide structure of the present invention is：
1. scattering of the light in longer communication process can repeatedly be corrected and polymerize to a less scope by the present invention
Output is, it can be achieved that uniform propagation of the light in light-guiding mechanism afterwards, so as to fulfill the uniform effect of vision, the light after multiple optically focused
Line loss is lost seldom, effectively increases light utilization；
2. the present invention does not use traditional light guide structure, and employs new-type light guide structure, material of the invention only LED
Light source and guide-lighting block, material configuration is few, and simple in structure, small volume, effectively increases space availability ratio；
3. easily manufactured without traditional zigzag structure, quality is good after shaping, and even photosensitiveness is good, optimizes light guide structure
Appearance, greatly improves the degree of recognition of client.
