Specific embodiment
Fig. 1 shows the structural representation of the embodiment of headlight of the invention 100.According to this hair
Bright headlight 100 includes at least two light sources, acts on the first optical unit 2 and second of light source
Optical unit 3 and lightproof unit 4.Light source may be designed as such as LED light source or xenon
The conventional light sources such as HID.Primary optics, such as lens can be designed with LED light source,
So as to the light of LED chip is by lens outgoing.First optical unit 2 preferably may be designed as accompanying drawing 1
In the reflector that shows, or be designed to be able to converge the lens (not shown) of the light beam from light source,
Wherein, the first optical unit 2 include the top optical processor 21 that is used cooperatively with the first light source 11 with
And the bottom optical processor 22 used cooperatively with secondary light source 12.Therefore, top of the invention
Optical processor 21 and bottom optical processor 22 can for example be designed as the reflector shown in accompanying drawing or not show
The lens for going out.Lightproof unit 4 may be designed as the knot that shadow shield or unthreaded hole etc. are capable of partial occlusion light beam
Structure.
Second optical unit 3 is preferably designed for lens, and including upper unit 31 and lower unit
32.The lens arrangement of the lens arrangement of upper unit 31 and lower unit 32 is simultaneously different so that two
Individual part has different focal lengths respectively.Wherein in a kind of embodiment, as illustrated in FIG. 1, on
Portion's unit 31 is designed as biconvex lens, and lower unit 32 is designed as planoconvex spotlight, i.e. the two parts
The surface towards light source there are different structures and profile, but upper unit 31 and lower unit
32 lens arrangement shared exiting surface, i.e. exiting surface are designed as single smooth.In another embodiment
In, Fig. 1 is not showed that, upper unit 31 is designed as biconvex lens, and lower unit 32 is designed
It is the biconvex lens with different curvature, thus, the surface toward and away from light source of lens is all not
It is continuous.
The upper part of lens has the first focus F1, and low portion has the second focus F2,
Wherein, the first focus F1 is close to away from lightproof unit 4 near lens, and the second focus F2
Lightproof unit 4 or the edge in lightproof unit 4.The first light from the first light source 11
R1 is thus burnt by second by being blocked the partial occlusion of unit 4 after the reflection of top optical processor 21
Point F2 projects outgoing on the latter half of the second optical unit 3.From secondary light source 12 second
Light R2 projects lens by being directly over the first focus F1 after the reflection of bottom optical processor 22
Upper unit 31 on.Headlight of the invention 100, the first focus F1 and the second focus F2
All it is preferably on the optical axis X of headlight 100, and from light source to the light of the second optical unit 3
The side in beam path is looked up, and the first focus F1 is located at behind the second focus F2, and positioned at second
Between focus F2 and lens.This is so that the light only from the first light source 11 can be blocked list
Unit 4 blocks, and forms desired light type, but the light from secondary light source 12 can't be blocked
Unit 4 is blocked, but is directly all projected in the upper unit 31 of lens.
In situations where it is preferred, the first focus F1 of the upper unit 31 of the second optical unit 3 is located at
At 4th focus F4 of bottom optical processor 22, and the second focus F2 of lower unit 32 is located at
At 3rd focus F3 of top optical processor 21, or, the upper unit of the second optical unit 3
31 the first focus F1 overlaps with the 4th focus F4 of bottom optical processor 22 substantially, and bottom
Second focus F2 of unit 32 overlaps with the 3rd focus F3 of top optical processor 21 substantially.Or,
In the case of other are preferred, the 3rd focus F3 of top optical processor 21 is located at lower unit 32
The second focus F2 vicinity, and bottom optical processor 22 the 4th focus F4 be located at top list
The vicinity of the first focus F1 of unit 31.
Additionally, in the unshowned embodiments of Fig. 1, reflector can be replaced can converge from light source
Light beam lens.This is thus, it is possible to form such favourable light path, the i.e. light of the first light source 11
Thus line projects the second optics list by being blocked the partial occlusion of unit 4 after the convergence of the first lens
On the lower unit 32 of unit 3, the light of secondary light source 12 is directly projected by after the convergence of the second lens
Onto the upper unit 31 of the second optical unit 3, and can't be influenceed by lightproof unit 4.
Additionally it should know, in other embodiments replaced, top optical processor 21 can be anti-
Emitter, and bottom optical processor 22 is lens, or top optical processor 21 is lens, bottom
Optical processor 22 is reflector.
Fig. 2 shows the structural representation of another embodiment of headlight of the invention 100.For
Description it is succinct, only schematically show the part light path of headlight 100 in Fig. 2.In the embodiment
In, in order to further improve the efficiency and central point light intensity of distance light light path, additional optical treatment can be set
Device 23, such as reflector, so that after being reflected through bottom optical processor 22, it is impossible to enter second
The ray-collecting of the lens of optical unit 3 gets up, and focuses to the lower unit of the second optical unit 3
32 the second focus F2 (or near).Then, light is reflexed to such as plane mirror 24
The lower unit 32 of the second optical unit 3, and by collimated outgoing.Herein, additional optical treatment
Plane mirror 24 at the focus F2 of device 23 and second can also be other arbitrary face type reflectors
Combination, to realize above-mentioned functions.
Fig. 3 shows the distance light light distribution schematic diagram of the embodiment of headlight of the invention 100, and
And Fig. 4 shows the dipped beam light distribution schematic diagram of the embodiment of headlight of the invention 100.According to
Headlight of the invention 100 can be favourable the function of realizing far lighting and lower beam illumination, and root
It is desired near to obtain by activating the first light source 11 and/or secondary light source 12 according to the demand of user
Light and/or far lighting function.Additionally, and do not need mobile shade 4 in the case of, headlight
100 can switch between two kinds of mode of operations of dipped beam and distance light.
The preferred embodiments of the present invention are these are only, is not intended to limit the invention, for ability
For the technical staff in domain, the present invention can have various modifications and variations.It is all it is of the invention spirit and
