Description
Technical field
The present invention relates to a kind of car light heavy wall concentrator ray structure, belong to car light concentrator technical field.
Background technology
After increasingly being generalized using LED as vehicle lamp light source, the regulation performance basic except meeting, increasing car light
Start to pursue more novel appearance and modeling, the implementation of light fixture function is also more and more diversified.Heavy wall concentrator is conventional
A kind of implementation.At present, existing heavy wall concentrator has following two conventional light emitting species：
1st, using LED/light source and heavy wall concentrator direct projection：
As shown in figure 1, the light that LED/light source 1 is exhaled, reassembles by the Fresnel decorative pattern at the back of concentrator 2
Together, parallel rays is internally formed in concentrator, the decorative pattern for eventually passing concentrator surface diffuses to all directions, to meet light
Learn the requirement of regulation.The pattern capacity usage ratio is high, but can cause lighting open defect, and after LED is lighted, outward appearance has significantly
LED particle sense, lighting effect is uneven；And if concentrator depth is shallower, the problem of rear wiring board outward appearance is visible can be caused.
2nd, reflected using LED/light source and heavy wall concentrator：
As shown in Fig. 2 the light that LED/light source 1 is exhaled, is all-trans through the optical patterns on the parabola of concentrator 3
Penetrate to form parallel rays, the decorative pattern for eventually passing concentrator surface diffuses to all directions, to meet the requirement of optics regulation.Should
Luminous pattern can efficiently solve the particle of LED after above-mentioned lighting, but overall capacity usage ratio is low, concentrator the top
Dark space can be formed because light can not be covered, and it is high to LED positioning accuracy request.
The content of the invention
The technical problem to be solved in the invention is：Existing car light heavy wall concentrator ray structure, or cause outward appearance to have
Obvious LED particle sense, lighting effect is uneven, and if when concentrator depth is shallower, rear wiring board outward appearance can be caused visible
The problem of；Or overall capacity usage ratio is low, concentrator the top can form dark space because light can not be covered, and to LED's
Positioning accuracy request is high.
The present invention takes following technical scheme：
A kind of car light heavy wall concentrator ray structure, including LED circuit board, LED particle 1, corner-type heavy wall concentrator 4；
The corner-type heavy wall concentrator 4 is inner to have the Fresnel decorative pattern for being used for producing directional light, and corner has total reflection tiltedly flat
Face；The outer end face of corner-type heavy wall concentrator 4 has the decorative pattern that can spread light；The LED particle is fixed on LED line road
On plate, and it is corresponding with the position that corner-type heavy wall concentrator 4 is inner.
Further, the corner-type heavy wall concentrator 4 is L-shaped.
Further, the directive and the corner-type heavy wall optically focused of the parallel rays through the total reflection tapered plane reflection
The length direction of the outer end of device 4 is consistent.
Further, the corner of the corner-type heavy wall concentrator 4 is 90 °.
The beneficial effects of the present invention are：
1) lighting effect evenly can be obtained, it is to avoid LED particle sense and lighting dark space problem that traditional design is brought；
2) the problem of traditional direct-injection type concentrator wiring board outward appearance is visible can effectively be solved；
3) capacity usage ratio is higher；
4) possess the advantage of the luminous pattern of existing two kinds of concentrators, on the premise of a small amount of energy is lost, obtain more
Uniform lighting effect；And avoid concentrator depth it is shallower caused by the not visible problem of appearance of wiring board under lighting state,
Save the longitudinal space of light fixture.
5) to light fixture appearance, after many-sided Integrated comparative such as bulk and capacity usage ratio, the invention has
There is certain advantage.

Embodiment
The present invention is further described with specific embodiment below in conjunction with the accompanying drawings.
Referring to Fig. 3, a kind of car light heavy wall concentrator ray structure, including LED circuit board, LED particle 1, corner-type heavy wall
Concentrator 4；The corner-type heavy wall concentrator 4 is inner to have the Fresnel decorative pattern for being used for producing directional light, and corner has complete
Reflect tapered plane；The outer end face of corner-type heavy wall concentrator 4 has the decorative pattern that can spread light；The LED particle is fixed
In LED circuit board, and it is corresponding with the position that corner-type heavy wall concentrator 4 is inner.
In this embodiment, referring to Fig. 3, the corner-type heavy wall concentrator 4 is L-shaped.
In this embodiment, referring to Fig. 3, the directive and the corner of the parallel rays through the total reflection tapered plane reflection
The length direction of the outer end of formula heavy wall concentrator 4 is consistent.
In this embodiment, the corner of the corner-type heavy wall concentrator 4 is 90 °.
Concrete principle is as shown in figure 3, the light that LED1 is exhaled, is formed by the Fresnel decorative pattern at the back side of heavy wall concentrator 4
Parallel rays, collimated light beam, which is got on the inclined-plane of concentrator, forms total reflection so that radiation direction deflects, along our institutes
The direction needed continues to propagate, and is spread light finally by the decorative pattern in concentrator surface, to meet the requirement in regulation.
LED particle sends stable light energy, by the optical patterns formation collimated light beam at the concentrator back side, collimated light beam
By the side wall formation total reflection of concentrator corner during concentrator internal communication so that light trend deflects to regulation
Required light direction, and the decorative pattern for continuing to be propagated up to by concentrator surface is diffused to each angle.Described turns
Angie type heavy wall concentrator can be made of PMMA or PC or the high material of other transmitances, and the angle of its corner can be to appoint
What angle is not limited only to right angle.
The present invention can obtain lighting effect evenly, it is to avoid LED particle sense and lighting dark space that traditional design is brought
Problem；The problem of traditional direct-injection type concentrator wiring board outward appearance is visible can effectively be solved；Capacity usage ratio is higher；Possess existing
The advantage of the luminous pattern of two kinds of concentrators, on the premise of a small amount of energy is lost, obtains more uniform lighting effect；And keep away
The visible problem of appearance of wiring board under the shallower caused not lighting state of concentrator depth is exempted from, the longitudinal direction for saving light fixture is empty
Between；To light fixture appearance, after many-sided Integrated comparative such as bulk and capacity usage ratio, the invention has certain
Advantage.
Above is the preferred embodiments of the present invention, those of ordinary skill in the art can also enter on this basis line translation or
Improve, on the premise of the total design of the present invention is not departed from, these conversion or improvement should all belong to claimed
Within the scope of.
