Ask, and "cut-off"line is clear, drives and feels that security reliability is high.
Driving mechanism has a variety of implementations, such as can be by the way of energization magnetic, the driving of this energization magnetic
Mode refers to the prior art.
Elaborate below in conjunction with the accompanying drawings to the structure and the course of work of the present invention.
As shown in Figure 1, headlight module includes upper reflector 10, lower reflector 20, radiator 30, lens 40, sleeve 50, gear
Ray machine structure 60, upper fixation spring tab 70a, lower fixation spring tab 70b, upper LED light source 80a, lower LED light source 80b, 90 and of Power conversion board
Fan 100.
Cooling system in the present invention includes radiator 30, upper fixation spring tab 70a, lower fixation spring tab 70b and fan 100.
Upper fixation spring tab 70a, lower fixation spring tab 70b can be incited somebody to action while fixation LED light source using its own excellent heat conductivility
Self heat is radiated in air in time.
During work, first fixed shrapnel 70a (can use stainless steel tension force shrapnel) is set upper LED light source 80a pressures
On the upper table surface 31a of radiator locating platform 31, lower LED light source 80b is pressed on radiator positioning and put down by lower fixation spring tab 70b
On the following table 31b of platform 31, then the bottom of upper LED light source 80a and lower LED light source 80b is held snugly against in radiator 30
On locating platform 31, so that on the one hand ensure that LED light source 80a and the position of lower LED light source 80b will not move, the opposing party
Face is also beneficial to improve radiating efficiency.
Then upper reflector 10 and lower reflector 20 are arranged on radiator 30 respectively, i.e., are sequentially passed through using screw
It is corresponding on the upper table surface 31a of upper reflector location hole 131 and radiator locating platform 31 on reflector positioning plate 13
Mounting hole, so that upper reflector 10 is tightly held on the upper table surface 31a of radiator 30；Likewise, using screw successively
Phase through on the following table 31b of lower reflector location hole 131 and radiator locating platform 31 on lower reflector positioning plate 23
Corresponding mounting hole, so that lower reflector 20 is tightly held on the following table 31b of radiator 30；And in radiator 30
Power conversion board 90 and fan 100 is fixedly mounted in rear side away from sleeve 50, is in the light mechanism 60 in the installed in front of radiator 30.
During mounted lens, lens 40 enter from the opening of 52 side of fixed seat of sleeve 50, and along cylinder inboard wall to cylinder
Body front end is moved at the inclined-plane of limited block 54, and the inclined-plane of rear end along the limited block 54 of lens 40 continues to move forward and struts claw 53
The limited block 54 of front end, final lens 40 enter the stop zone between limited block 54 and spacing flange 51, at this time before claw 53
End is elastic recovery to home position, then lens 40 are tightly buckled in sleeve 50.
The sleeve 50 for installing lens 40 passes through the process Installation hole 56 in fixed seat 52 and fastening thread hole and radiator
30 buttcover plate 33 is tightly secured together.
Upper LED light source 80a and lower LED light source 80b are connected by winding displacement with Power conversion board 90 respectively, are connected during work
LED light source 80a, lower LED light source 80b and Power conversion board 90, upper LED light source 80a and the equal electrified light emittings of lower LED light source 80b, and
Reflecting surface 111 of the light that upper LED light source 80a is sent through upper reflector 10 reflects, and under the light warp that lower LED light source 80b is sent
The reflecting surface 211 of reflector 20 reflects, i.e., the light that upper LED light source 80a, lower LED light source 80b are sent first passes around upper and lower anti-
The primary event of light cup, the light after reflection project away after the refraction of 40 secondary optics of lens, final upper LED light source 80a,
The light that lower LED light source 80b is sent effectively is superimposed to obtain the emergent light of more preferable light type, brightness and light efficiency higher.
In addition, after upper reflector 10 and lower reflector 20 are fixed on radiator 30, different sleeve connections can be passed through
Various sizes of lens, whole headlight module can also use different mounting brackets inside different car lights, flexibly
The structure of conversion can more adapt to different headlight for vehicles.
