Technical field
The invention belongs to technical field of automobile illumination, and in particular to a kind of transparent baffle for headlamp module.
Background technology
In the design of the double optical modules of LED headlamps, reflective dipped beam be aided with light collecting distance light have become it is a kind of more often
The design concept seen.Wherein dipped beam dead line light type is realized by baffle, and distance light light type is then generally realized with concentrator.So
Two kinds of parts of baffle and concentrator are indispensable in conventional double optical modules.For the above situation, the present invention proposes a kind of use
In the transparent baffle of headlamp module, module still meets the light distribution of regulation and main engine plants' proposition after baffle is merged with concentrator
Demand, to be advanced optimized to the volume and cost of headlamp module module.
Invention content
The purpose of the present invention is overcome the prior art to there is baffle in conventional double optical modules to lack one with two kinds of parts of concentrator
Can not the problem of, a kind of simple and compact for structure, the lower-cost transparent baffle for headlamp module is provided.
The technical solution adopted by the present invention to solve the technical problems is：A kind of transparent baffle for headlamp module,
The baffle is U-shaped integrated transparent configuration, including the connecting plate between two wing plates and two wing plate ends, the connection
Concentrator is equipped among plate, the concentrator is the gun barrel structure with striated surface, corresponding with the concentrator described
The another side of connecting plate is outgoing plane, and the upper surface that the connecting plate is connect with the concentrator is the dipped beam plane of incidence.
Further, several reinforcing ribs are fixed on the surface of two wing plates.Described in being fixed on the surface of the wing plate
Reinforcing rib can improve the mechanical strength of the baffle.
Further, wherein at least there is the reinforcing rib that a reinforcing rib is mutually parallel perpendicular to other.So that
Reinforcing rib " king " the font arrangement or the arrangement of " well " font, can further increase the mechanical strength of the baffle.
Further, the thickness of every reinforcing rib is 1 ± 0.5mm, and width is 1 ± 0.5mm.The thickness of 1mm
Optics can not be had an impact while the mechanical strength for improving baffle with width.
Further, the opening shape of the concentrator is ellipse.The concentrator of ellipse further improves optically focused
Effect.
Further, the making material of the baffle is transparent PC PMMA materials.PC materials (makrolon) or
The light transmittance of person PMMA materials (polymethyl methacrylate) can reach 90% or more, and translucent effect is good.
Further, the dipped beam plane of incidence and horizontal line are in 0~30 ° of angle.The design of 0~30 ° of angle can allow part dipped beam
Light injects transparent baffle, these light after baffle inner total reflection comes out to three area's light filling of dipped beam, the perfect design of dipped beam,
And improve the utilization rate of dipped beam.
A kind of advantageous effect of transparent baffle for headlamp module of the present invention is：After baffle is merged with concentrator
The light distribution demand that module still meets regulation and main engine plants propose, it is further excellent to carried out to the volume and cost of module
Change, and the transparent baffle is simple and compact for structure, mechanical strength is good, and cost is relatively low.

Specific implementation mode
In conjunction with the accompanying drawings, the present invention is further explained in detail.These attached drawings are simplified schematic diagram, only with
Illustration illustrates the basic structure of the present invention, therefore it only shows the composition relevant to the invention.
A kind of specific embodiment of transparent baffle for headlamp module of the present invention as shown in FIG. 1 to FIG. 3, one
Transparent baffle of the kind for headlamp module, baffle are U-shaped integrated transparent configuration, including two wing plates 1 and two 1 ends of wing plate
Between connecting plate 11, be equipped with concentrator 3 among connecting plate 11, concentrator 3 is the gun barrel structure with striated surface, and poly-
The another side of 3 corresponding connecting plate 11 of light device is outgoing plane 5, and the upper surface that connecting plate 11 is connect with concentrator 3 enters for dipped beam
Penetrate face 4.Embodiment still more preferably, the dipped beam plane of incidence 4 are in 0~30 ° of angle with horizontal line, and 0~30 ° of angle design can
Allow part dipped beam light to inject the transparent baffle, these light baffle inner total reflection come out after to three area's light filling of dipped beam, it is perfect
The design of dipped beam, and improve the utilization rate of dipped beam.
In order to improve the mechanical strength of the transparent baffle, several reinforcing ribs 2 are fixed on the surface of two wing plates 1.Wherein, until
The reinforcing rib 2 that a rare reinforcing rib 2 is mutually parallel perpendicular to other so that reinforcing rib 2 is arranged at " king " font or " well "
Font is arranged, and can further increase the mechanical strength of the transparent baffle in this way.Specifically, the thickness of every reinforcing rib 2 is 1
± 0.5mm, width are 1 ± 0.5mm, and the reinforcing rib of 1mm left and right thicknesses and 1mm or so width can be in the machine for improving baffle
Optics is not had an impact while tool intensity.
Further, concentrator 3 is gun barrel structure and surface carries fringe-like structures, and fringe-like structures are conducive to remote
Light and photochromic optimization；Opening shape is ellipse, and oval concentrator 3 further improves spotlight effect.
PC materials (makrolon) or PMMA materials (poly- methyl is made by the material of transparent PC either PMMA in baffle
Methyl acrylate) there is preferable light transmittance, light transmittance can reach 90% or more, translucent effect is good.Further, baffle
Upper surface is aluminized processing, and surface, which is aluminized, further increases the reflectivity of distance light light 61.Preferably, the upper surface of transparent baffle is
Without covering reflecting material, no covering reflecting material is a bigger improvement from technique, is covered in general Transparent Parts
Reflecting material, such as aluminize, but the quality of aluminium coated should be uncontrollable at present, especially form "cut-off"line
Structure at, the quality of aluminium coated will have a direct impact on the visual effect of dead line, even results in and can't pass dipped beam relevant laws and regulations.
A kind of operation principle of the transparent baffle for headlamp module of the present embodiment：As shown in figure 3, dipped beam light 41
The larger part of light sent out forms dipped beam dead line by the dipped beam plane of incidence 4 of baffle, at least partially through the upper surface of baffle
The dipped beam plane of incidence 4 inject gun barrel structure concentrator 3 inside, again from the outgoing plane of the front surface of baffle after multiple total reflection
5, which form dipped beam fringence 42, projects, this just forms 3rd area of dipped beam and provides luminance compensation for part regulation point.Distance light LED6 is sent out
Light inject inside the concentrator 3 of gun barrel structure, project, formed remote from the outgoing plane 5 of the front surface of baffle again after total reflection
Anaclasis line 62, last dipped beam fringence 42 and distance light fringence 62 all pass through lens 7.
It should be appreciated that specific embodiment described above is only used for explaining the present invention, it is not intended to limit the present invention.By
The obvious changes or variations that the spirit of the present invention is extended out are still in the protection scope of this invention.
