The kind of drive, first, structure is increasingly complex, not only the cost is relatively high for manufacture, but also increasing due to parts, causes to hide
The reliability of ray machine structure reduces；Second, transmission efficiency is high without direct drive mode, energy consumption is added, consequence is chopping mechanism
During work, its caloric value bigger, causes its working performance and service life all to decline；Third, such chopping mechanism generally will
Motor is arranged in the positive front end of light source or end to the front, consequence：When headlight works, the magnet steel of motor is because high temperature demagnetizes or disappears
Magnetic, makes chopping mechanism cisco unity malfunction or even fails, reliability reduces.In actual use, the temperature inside car headlamp
Degree is very high：Halogen light source caloric value is high, from center around up to 450-150 DEG C；Halogen lamp is used using xenon light source ratio
The headlight of light source, low 50-100 DEG C are wanted in same position.The magnet steel of micromachine, is lower-cost ferrite magnetic
Or junior Rare-Earth Magnetic, tolerable temperature is generally all below 125 DEG C, and when temperature is higher than this value, its performance, which just occurs, to decline
Move back or even disappear.The thus structure of such a mode, may be only available for the relatively small number of headlamp that generates heat（Such as LED light）, it is difficult to suitable
For halogen lamp or xenon lamp, without general applicability.
