Specific implementation mode
The embodiment of the present invention is described below in detail, examples of the embodiments are shown in the accompanying drawings.Below with reference to
The embodiment of attached drawing description is exemplary, it is intended to for explaining the present invention, and is not considered as limiting the invention.
LED dipped beams module 100 according to the ... of the embodiment of the present invention is described in detail below with reference to Fig. 1-Fig. 3.
LED dipped beams module 100 according to the ... of the embodiment of the present invention may include：Illumination distances projecting unit 10 and illumination width
Projecting unit 20, illumination distances projecting unit 10 and illumination width projecting unit 20 are disposed adjacent, and illumination distances projection is single
The light that member 10 and illumination width projecting unit 20 emit is superimposed to form dipped beam light type.It is understood that illumination distances project
Unit 10 can make dipped beam light type meet requirement of the LED dipped beams module 100 to illumination distances, and illumination width projecting unit
20 can make dipped beam light type meet requirement of the LED dipped beams module 100 to illumination distances, and such dipped beam light type can meet simultaneously
Requirement of the LED dipped beams module 100 to illumination distances and illumination width, so as to solve the illumination in traditional LED dipped beams module
Contradiction between distance and illumination width can make the dipped beam light type that LED dipped beams module 100 projects be uniformly dispersed, Er Qieke
So that LED dipped beams module 100 is simple in structure, it is at low cost.
Wherein, as shown in Figure 1, illumination distances projecting unit 10 and illumination width projecting unit 20 are divided in a lateral direction
Cloth, and illumination distances projecting unit 10 and illumination width projecting unit 20 are staggered arrangement in a longitudinal direction.LED dipped beams in this way
Module 100 can meet the requirement of vehicle, and can so that 100 shape of LED dipped beams module is novel.Wherein, for illumination away from
It is not limited in the specific arrangement of horizontal direction (i.e. the left and right directions of vehicle) from projecting unit 10 and illumination width projecting unit 20
It is fixed, that is to say, that illumination distances projecting unit 10 can be arranged in the inside of illumination width projecting unit 20, can also be arranged
The outside of illumination width projecting unit 20.
Optionally, the structure of illumination distances projecting unit 10 and illumination width projecting unit 20 can be identical.Such zero
Part can be general, and can be improved in order to the arrangement of illumination distances projecting unit 10 and illumination width projecting unit 20
The structural reliability of LED dipped beams module 100.
As shown in Fig. 2, illumination distances projecting unit 10 and illumination width projecting unit 20 may each comprise：It is LED light 11, anti-
Mirror 12, lens 13 and barrier support 14 are penetrated, LED light 11, speculum 12 and lens 13 are separately mounted on barrier support 14.Specifically
Ground, LED light 11 may be mounted at the rear portion of barrier support 14, and speculum 12 may be mounted at the top of barrier support 14, lens
13 may be mounted at the front of barrier support 14.The light that LED light 11 is sent out is by can be by 12 emission process of speculum
The adjustment of first time, there are one particular procedure regions for tool on barrier support 14, and the light reflected through speculum 12 is using baffle
Behind the particular procedure region of holder 14, not due to the opticpath of illumination distances projecting unit 10 and illumination width projecting unit 20
Together, the two parts for eventually passing through the projection of lens 13 need rational superposition, collectively constitute ideal dipped beam light type.
As shown in figure 3, be formed with focus between LED light 11 and lens 13, the distance of center to the focus of lens 13 is the
The distance of one focal length a, focus to LED light 11 are the second focal length b, and the ratio between the first focal length a and the second focal length b is in 1.2-2
Between.By limiting the proportionate relationship between illumination distances projecting unit 10 and two focal lengths of illumination width projecting unit 20,
It can make light that two projecting units are launched preferably is superimposed to form dipped beam light type.Preferably, the first focal length a and second
Ratio between focal length b can be 1.5.For example, the first focal length a can be 45mm, the second focal length b can be 30mm.
Further, the first focal length a and the second focal length b of illumination distances projecting unit 10 and illumination width projecting unit 20
Between ratio between difference can be between 0-0.6.By rationally controlling illumination distances projecting unit 10 and illumination width
The difference between ratio between the first focal length a and the second focal length b of projecting unit 20 can make two projecting unit transmittings
The light gone out is preferably superimposed and forms dipped beam light type.
Wherein, the barrier support 14 of illumination distances projecting unit 10 and the barrier support 14 of illumination width projecting unit 20 are solid
Fixed connection.It can make LED dipped beams 100 globalities of module preferable in this way, and can so that 100 structure of LED dipped beams module can
It leans on.
Optionally, speculum 12 and lens 13 are mounted on by fastener on corresponding barrier support 14 respectively.For example, gear
It is provided with corresponding mounting hole on board mount 14, is respectively arranged with mounting hole on speculum 12 and lens 13, fastener passes through pair
Two mounting holes answered are the two to be fixedly connected.
