Description
Technical field
The present invention relates to a kind of car headlamp distance-light one light emitting diode (LED) PES units, belong to car light design
Technical field.
Background technology
For the headlight of distance-light one, conventional distance-light function switch mode has two kinds：Electromagnetism Vavle switching shadow shield
With fixed nontransparent shadow shield.
Using electromagnetism Vavle switching shadow shield scheme the defects of be cost is high, volume is big, weight is big, function switch when noise
Greatly.
It is that dividing plate has certain thickness using the defects of fixed nontransparent shadow shield, for the boundary of far and near photoimaging
Obvious seam can be caused, forms the filaments of sun, influences Driver Vision experience.Referring specifically to Fig. 1, dipped beam light a is by lens
Focal position, light is parallel with optical axis after lens, and dipped beam light b is without lens focus position, the joining with optical axis
Before lens focus, so light is diffusing light after lens, it will not intersect with optical axis, other dipped beam light can be by dividing plate
Block, without going past lens.And all distance light light, it is all similar with dipped beam light b due to the stop of dividing plate, by lens
After be diffusing light, will not intersect with optical axis.Distance light light because of the thickness reason on dividing plate head, can not by lens focus, because
This dipped beam light has the angular interval of a vacancy with shooting angle of the distance light light after lens, causes dipped beam and distance light
Split off and, so as to cause obvious seam, form the filaments of sun, influence Driver Vision experience.
The content of the invention
The technical problem to be solved in the invention is：Existing car headlamp distance-light one light emitting diode (LED)
PES units, or the scheme using electromagnetism Vavle switching shadow shield, cause cost is high, volume is big, weight is big, function switch when noise
Greatly；Or fixed nontransparent shadow shield is used, certain thickness be present, can be caused substantially for the boundary of far and near photoimaging in dividing plate
Seam, formed the filaments of sun, influence Driver Vision experience.
The present invention takes following technical scheme：
A kind of car headlamp distance-light one LED P ES units, including dividing plate 2, transparent shadow shield 4, lens
5th, dipped beam LED, distance light LED；The 4 rectangular body of transparent shadow shield, is arranged on the nearly lens side of dividing plate 2, its upper surface with
The upper surface of dividing plate 2 is concordant or close to concordantly；The focus of lens 5 is located on the upper surface of the transparent shadow shield 4；The dipped beam
LED is located at distance light LED top；The light Part I of the dipped beam LED transmittings is sheltered from by dividing plate 2, and Part II is penetrated
The transparent upper surface of shadow shield 4 transmission and in the transparent inner side of shadow shield 4, so as to form dipped beam dead line；The distance light LED hairs
The light penetrated passes through transparent shadow shield 4, due to incidence angle it is larger realize transmission, through lens focus light after lens reflect
Form directional light so that realize and be seamlessly connected when distance-light switches, between distance-light light type.
Further, the light Part II of dipped beam LED transmittings is penetrated to be formed in the transparent upper surface of shadow shield 4 and transmitted, and
Transparent shadow shield 4 is internally formed multiple total reflection.
Further, the surface treatment of dividing plate 2 adds for dermatoglyph and aluminized, and realizes the effect of increase light efficiency or softening veiling glare.
A kind of car headlamp distance-light one LED P ES units, the car headlamp distance-light are integrally sent out
Optical diode PES units are not provided with dividing plate, and the lateral dimension of transparent shadow shield 4 reaches enough thickness, makes to be located at transparent shading
The light at the upper surface close to sources position of plate 4 all realizes total reflection, is shut out the light so as to can equally reach, and forms dipped beam dead line
Effect.
The beneficial effects of the present invention are：
1) avoid using electromagnetism Vavle switching shadow shield, reduce cost, reduce volume, mitigate weight, avoid function switch
When caused noise.
2) because the effect of transparent shadow shield, the boundary of far and near photoimaging will not cause seam, eliminate the filaments of sun, improve
Driver Vision, make driver that there is more preferable road surface driving experience.
3) it is skillfully constructed, cost is relatively low, easy to implement.
4) surface treatment of dividing plate adds for dermatoglyph and aluminized, and realizes the effect of increase light efficiency or softening veiling glare.

Embodiment
The present invention is further described with specific embodiment below in conjunction with the accompanying drawings.
Embodiment one：
Referring to Fig. 2, a kind of car headlamp distance-light one LED P ES units, including dividing plate 2, transparent shading
Plate 4, lens 5, dipped beam LED, distance light LED；The 4 rectangular body of transparent shadow shield, the nearly lens side of dividing plate 2 is arranged on, its
Upper surface is concordant with the upper surface of dividing plate 2 or close to concordantly；The focus of lens 5 is located on the upper surface of the transparent shadow shield 4；
The dipped beam LED is located at distance light LED top；The light Part I of the dipped beam LED transmittings is sheltered from by dividing plate 2, and second
Part, which is penetrated, to be transmitted in the transparent upper surface of shadow shield 4 and is internally formed total reflection in transparent shadow shield 4, so as to form dipped beam cut-off
Line；
The dipped beam light that transparent shadow shield stops is not run into, and dipped beam light type will be formed after projecting lens.And run into
The dipped beam light that bright shadow shield stops, it will enter from the top of shadow shield inside transparent shadow shield.Due to the effect of total reflection,
This some light will be emitted below shadow shield, and cannot be introduced into lens, just can so form dipped beam dead line.
The light of the distance light LED transmittings passes through transparent shadow shield 4, transmission is realized because incidence angle is larger, through lens
The light of focus forms directional light after lens reflect so that realizes and is seamlessly connected when distance-light switches, between distance-light light type.
This programme transmits the principle with being totally reflected using light, dipped beam light and distance light light is each passed through lens Jiao
Point, it can make to realize seamless connection between distance-light light type.
Referring to Fig. 2, the light Part II of dipped beam LED transmittings is penetrated to be transmitted in the transparent upper surface of shadow shield 4, and in transparent screening
Tabula rasa 4 is internally formed multiple total reflection.
The surface treatment of dividing plate 2 adds for dermatoglyph aluminizes, and realizes the effect of increase light efficiency or softening veiling glare.
Embodiment two：
The light of dipped beam system is concentrated mainly near lens focus, and the effect of dividing plate is unnecessary in stop dipped beam system
Light enters on the right side of shadow shield, and veiling glare is caused to dipped beam light type.If the thickness of shadow shield is enough long, can include all near
Light incident ray, then it can cancel dividing plate.Then embodiments below is used：
A kind of car headlamp distance-light one LED P ES units, the car headlamp distance-light are integrally sent out
Optical diode PES units are not provided with dividing plate, and the lateral dimension of transparent shadow shield 4 reaches enough thickness, makes to be located at transparent shading
The light at the upper surface close to sources position of plate 4 all realizes total reflection, is shut out the light so as to can equally reach, and forms dipped beam dead line
Effect.
The present invention had both avoided bulky mechanical shadow shield, it also avoid distance caused by the nontransparent shadow shield of fixation
Light light type separates, and sound when completely eliminating distance-light function switch.
The more present magnetic valve scheme of the present invention, reduces cost, reduces weight, reduce volume, eliminate distance
Sound when light switches, fixed nontransparent shadow shield are compared, improve the linking between distance-light light type, driver is possessed more
Good road surface effect experience.
