Description
Technical field
The utility model relates to technical field of automobile parts more particularly to a kind of dimming devices of automobile lamp.
Background technique
Automobile lamp is an important appearance member in vehicle complete vehicle, even more an indispensable functor, regulation part,
The safety and reliability for needing to have certain.With the development of science and technology, information technology is advanced by leaps and bounds, people want car light
Ask also higher and higher, car light is no longer a simple light bulb, and increasingly tends to be intelligent.Before LED, DLP are projected in automobile
Application on headlight is more and more wider.At the same time, the part of lamp interior also becomes increasingly complex, and needs more structurally sound structure
It can support.According to national relevant regulations, lower beam headlamp must be equipped with screwdriver dimming device, when dipped beam luminous flux is no more than
When 2000lm, it is necessary to containing hand-operating light, need to be equipped with direct current generator, when dipped beam luminous flux is more than 2000lm, it is necessary to contain
It is with an automatic light meter, it is necessary to be equipped with stepper motor.When light dimming electric motor use is in upper and lower dimming device, light dimming electric motor is in gravity direction
Upper empty avoiding, lens group, DLP projecting subassembly only have two o'clock support in this direction；When light dimming electric motor use is in left and right dimming device
When middle, light dimming electric motor axis only has two o'clock support in Z-direction (gravity direction) empty avoiding, lens group, DLP projecting subassembly in this direction.
Under normal circumstances, the next on light since the automobile height under different loads is different if only selecting side translator dimming device
It sets and is affected to driver, can preferentially selection be dimmed up and down using motor dimming device.Therefore, before for translator light modulation
For illuminator, in generally existing only two o'clock support whole lens groups, DLP projecting subassembly gravity direction the problem of power.
Relatively common at present is the basis that will be adjusted screw or gear-driven screw rod and dim as screwdriver, will be dimmed
