Description
Technical field
The utility model is related to a kind of LED light source module darkening regulating mechanisms, are mainly used for automobile front.
Background technology
Existing automobile front mostly uses greatly halogen bulb or xenon lamp as illuminating source, the disadvantage is that energy consumption is big,
Calorific value is big, higher to the material requirements of peripheral component；Xenon lamp component size is big, is unfavorable for arranging, and light bulb lights speed
Degree is slow, and service life is short, and especially halogen lamp bubble point is bright rear rather dark, and driving at night is caused to easily cause visual fatigue.
Therefore, in recent years, LED light source module headlight is rapidly developed, but existing LED light source module distance-light darkening uses shading
Plate up and down adjustment structure be easy to cause the shake of light shape the disadvantage is that the vibration generated in the process of moving, is transmitted on car light,
Driver is set to generate visual fatigue, there are security risks.Therefore, the applicant once devised a kind of entitled " automobile front
LED distance-lights optics module ", and applied for Chinese patent, Patent No. ZL201620068220.2 is driven using solenoid valve and is connected
Bar swing adjusts barn door, efficiently solves jitter problem, and still, the production cost of solenoid valve is high, whole to improve
The processing cost of a LED light source module, reduces the competitiveness of product.
Invention content
The shortcomings that the purpose of this utility model is to overcome prior arts provides a kind of using motor gear rack drives
Rotation, motion stability, LED light source module darkening regulating mechanism at low cost.
The technical solution of the utility model LED light source module darkening regulating mechanism is：Include the peace of a LED light source module

The LED light source module darkening regulating mechanism of the utility model, LED light source module when in use, are typically in dipped beam
State, barn door are upturned, and light source is covered a part by barn door, realize dipped beam, when light to be become, direct current generator energization work
To make, gear is made to pass through arc-shaped rack and tooth plate, barn door is driven to be rotated down, light source does not have blocking for barn door, becomes distance light,
Realize nearly distance light darkening, when dipped beam to be become again, as long as the power supply of cut-out direct current generator, barn door is in reduction torsion spring and resetting block
Cooperation under, automatic rotation tilts, and becomes dipped beam again.This programme is driven using direct current generator, then is rotated by rack and pinion engagement,
Realize freely converting for nearly distance light, motion stability, reliable, the production cost of especially direct current generator is low, to reduce entire LED
The cost of light source module group improves product competitiveness.
