On, and the distance light light type and dipped beam light type for passing through lens forming qualification.But brightness requirement is continuous in car light novel at present
It improves, if light source, in such a way that plurality of LEDs is densely arranged, normal mirror is difficult to converge the light of plurality of LEDs.
Utility model content
To solve the above problems, the utility model proposes a kind of car headlamp for being equipped with multiple LED light sources, structure letter
It is single, the LED light issued can be focused and be conducted, light is transmitted to required position, improves automotive lighting effect.
Technical solution: the utility model proposes a kind of car headlamps for being equipped with multiple LED light sources, including LED seat
With the lens being arranged in above LED seat；The upper surface of the LED seat is provided with multiple LED light sources；The LED light source
Top is provided with silica gel light guide；The lower part of the silica gel light guide is provided with multiple inverted trapezoidal boss, each inverted trapezoidal
Groove is provided on the short bottom edge of boss, the bottom surface of the groove is outer convex spherical；Each LED light source is located at one
The underface of groove.
Further, the multiple LED light source is arranged at matrix.
Further, the surrounding of the silica gel light guide is integrally formed casting and is provided with plastic stent, the silica gel light guide
Plastic stent is provided with riveted structure.
Further, the outer wall of the plastic stent and the inner wall of LED seat are bolted to connection.
Further, the LED seat is fixedly arranged above lens mount；The lens are fixed in lens mount.
Further, the lower surface of the LED seat is provided with radiator
The utility model has the advantages that the utility model is collected the light that the matrix of LED light source arrangement issues, about by silica gel light guide
Beam, the focal plane for being transmitted to lens, then secondary light-distribution is carried out by lens, good road lighting is formed, automotive lighting effect is improved
Fruit.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the partial enlargement optical schematic diagram of the inverted trapezoidal boss of the utility model.
In figure: 1-LED lamp holder, 2- lens, 3-LED light source, 4- silica gel light guide, 5- inverted trapezoidal boss, 6- groove, 7- modeling
Expect bracket, 8- lens mount, 9- lens mount.
Specific embodiment
Such as Fig. 1, the utility model proposes a kind of car headlamps for being equipped with multiple LED light sources, including 1 He of LED seat
Lens 2；The lower surface of the LED seat 1 is provided with radiator 9, and upper surface is provided with multiple LED light sources 3 arranged at matrix,
The LED seat 1 is fixedly arranged above lens mount 8；The lens 2 are fixed in lens mount 8.
The top of the LED light source 3 is provided with silica gel light guide 4；The lower part of the silica gel light guide 4 be provided with it is multiple fall
Trapezoid boss 5 is provided with groove 6 on the short bottom edge of each inverted trapezoidal boss 5, and the bottom surface of the groove 6 is evagination
Spherical surface；Each LED light source 3 is located at the underface of a groove 6.
The light that the LED light source that dense matrix is arranged issues can be collected, constrain, is transmitted to lens 2 by silica gel light guide 4
Focal plane, then secondary light-distribution is carried out by lens 2, form good road lighting.
Detailed process is the light that LED light source issues, from the incidence of 4 one end of silica gel light guide, in inner full-reflection, then
It is transmitted on the focal plane of lens 2d, is emitted above silica gel light guide 4, the shooting angle in this time is due to multiple total reflection quilt
It is limited in a small angle range, all can carry out secondary light-distribution by lens 2.
It is because silica gel compares other transparent plastic materials with following good characteristic using the material that silica gel does light guide:
A, resistance to temperature is high, is up to 150 ° or more in light incident side temperature, and silica gel being capable of steady operation at these elevated temperatures.
B, resistance to ag(e)ing is good, and silica gel has the anti-aging property under very strong anti-aging property, especially high temperature.It is used for a long time
It will not cracking, change colour.
C, light conduction efficiency is high, the light transmission 94% of silica gel, is much higher than normal transparent plastic material.
D, silica gel good fluidity, good moldability can be made into wall thickness very flaky texture and needle point column structure.Commonly
Transparent material is limited by material flowability and mould process, and thickness is less than 2mm can not injection molding.
Silica gel product is soft, should not carry out design for assembly, the especially assembly such as screw connection place, common practices
It is thickening processing to be done into silica gel part border, then mode is fixed on plastic rubber bracket by hand, but later period hand assembled is imitated in this way
Rate is low, and silica gel part is very frivolous, is made by artificial external force of easily damaging.Therefore the surrounding one of the silica gel light guide 4
Molding casting is provided with plastic stent 7.
Plastic stent 7 is PET+GF using material, and the characteristics of PET+GF material is that intensity is good, the good, dimensional stability of rigidity
Good, high temperature resistant.After the production molding of plastic rubber bracket 7, it is placed in silica gel mould, is then poured silica gel again, make outside silica gel and plastic cement
Shell is inlayed integrally, and die sinking is taken out after solidification.
In order to guarantee being tightly combined between silica gel light guide 4 and plastic stent 7, it is unlikely to subsequent transportation, assembling process
In fall off, increase riveted structure in the design.Riveted structure further enhances the company of silica gel light guide 4 and plastic stent 7
Intensity is connect, can guarantee the assembly reliability and assembly efficiency of glue light guide 4 very well.
The outer wall of the plastic stent 7 and the inner wall of LED seat 1 are bolted to connection.
The light that the matrix of LED light source arrangement issues is collected, constrains, is transmitted to by silica gel light guide by the utility model
The focal plane of lens, then secondary light-distribution is carried out by lens, good road lighting is formed, automotive lighting effect is improved.
