Description
Technical field
The present invention relates to a kind of reflective automotive lamp unit, belong to car light technical field.
Background technology
As shown in figure 1, existing car light reflector element is typically made up of light source 1, speculum 2 and radiator 3, light source 1 is sent out
The diverging light gone out forms specific light distribution patterns after the reflection of speculum 2, and light source is then arranged on radiator 3, ensures it
Effective radiating.Under this form, the dead line of dipped beam be the border of light source 1 is imaged by the reflecting surface 2a in speculum 2 Lai
Realize, different reflectings surface is different for the position of light source 1, and its picture formed also can be different.Pass through different reflecting surface shapes
Into different pictures, required light distribution patterns are finally given.This traditional reflected version, light source 1 be with high dispersion angle,
Corresponding speculum 2 must have larger area, so as to reach specific efficiency.
Further, since specific light type is formed by the luminous border of light source 1, the quality of the position on its border for dead line
Have a great impact.But because the installation of light source 1 positions limitation, can exist in the luminous border all directions of light source certain
Tolerance variations, in this case, the dead line and light distribution patterns being correspondingly formed have very big fluctuation.
The content of the invention
The technical problem to be solved in the invention is：Existing reflective automotive lamp unit, because the installation of light source positions limit
System, can have certain tolerance variations in the luminous border all directions of light source, in this case, the dead line that is correspondingly formed and
Light distribution patterns have very big fluctuation；Because light source has compared with high dispersion angle, the area of corresponding speculum is larger, causes car light
Moulding is limited, while cost increase.
The present invention takes following technical scheme：
A kind of reflective automotive lamp unit, including radiator 51, if light is finally projected before direction is, direction where speculum
To be rear；Light source 11, translucent element 31, light-blocking member 41, speculum 21 are sequentially provided with the radiator 51 from front to back；From light
Source 51 to speculum direction has the angle tilted upward；The translucent element 31 is by the light collection that light source projects to light shielding part
Part 41, some light are covered by light-blocking member 41, some light directive speculum 21.
Further, the speculum 21 is made of one formula structure with light-blocking member 41.
Further, the reflective automotive lamp unit is automobile front lamp.
Further, light source 11, radiator 51 and transmissive element 41 are on the downside of speculum.
Further, the light source 11 is LED luminescence chips.
Further, the reflecting surface of the speculum 21 is class parabola.
Further, the speculum 21 is relatively fixed with light-blocking member 41.
The beneficial effects of the present invention are：
1) "cut-off"line of reflective dipped beam is realized by class light-blocking member, avoids conventional reflective automotive lamp unit
The fluctuation of "cut-off"line quality and cut-off line position caused by middle light source position error.
2) because transmissive element has carried out class collimation to emitting beam for light source, its beam size has obtained further pressure
Contracting so that the size of speculum can also reduce accordingly, enrich vehicle light shape, reduce cost.
3) because the presence of transmissive element, the light efficiency of whole system are substantially improved, no less than the light of traditional reflecting system
Effect.

Embodiment
The present invention is further described with specific embodiment below in conjunction with the accompanying drawings.
Referring to Fig. 1-Fig. 5, a kind of reflective automotive lamp unit, including radiator 51, if light is finally projected before direction is, instead
After direction where penetrating mirror is；Be sequentially provided with from front to back on the radiator 51 light source 11, translucent element 31, light-blocking member 41,
Speculum 21；There is the angle tilted upward from light source 51 to speculum direction；The light that the translucent element 31 projects light source
Line converges to light-blocking member 41, and some light is covered by light-blocking member 41, some light directive speculum 21.
In this embodiment, the speculum 21 is made of one formula structure with light-blocking member 41.
In this embodiment, the reflective automotive lamp unit is automobile front lamp.
In this embodiment, light source 11, radiator 51 and transmissive element 41 are on the downside of speculum.
In this embodiment, the light source 11 is LED luminescence chips.
In this embodiment, the reflecting surface of the speculum 21 is class parabola.
The light that light source 11 is sent passes through the refraction of transmissive element 31, after light-blocking member 41, then is irradiated to described anti-
Mirror 21 is penetrated, then road surface is projected after the light path design of speculum, forms required illumination light shape, if Fig. 6 is lower beam illumination
Illumination light shape signal of the function on vertical screen.
Embodiment two：
The present embodiment and the difference of embodiment one are：Speculum 21 is relatively fixed with light-blocking member 41.
The present invention realizes the "cut-off"line of reflective dipped beam by class light-shielding structure 41, avoids conventional reflective car
The fluctuation of "cut-off"line quality and cut-off line position in lamp unit caused by light source position error.Simultaneously as transmission member
Part 31 has carried out class collimation to emitting beam for light source 11, and its beam size has obtained further compression so that speculum
Size can also reduce accordingly.Further, since the presence of transmissive element, the light efficiency of whole system is substantially improved, no less than biography
The light efficiency of the reflecting system of system.
Above is the preferred embodiments of the present invention, those of ordinary skill in the art can also further convert on this basis
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.
