Most projectors use metal halogen lamps (Metal Halide). In the light state, the voltage of the bulb is about 60-80V, the gas pressure in the bulb is greater than 10kg / cm, the temperature is thousands of degrees, and the filament is in a semi-molten state. Therefore, in the boot state, it is strictly prohibited to vibrate, move the projector, to prevent the bulb burst, can not immediately turn off the power supply, to let the machine after the completion of automatic cooling, the damage caused by the machine cooling state of the power off is one of the most common repair reasons for the projector. In addition, reducing the number of switches is beneficial to the life of light bulbs.
Projector micro motor is also known as the projector micro deceleration motor, used in the projector lift drive, the main drive structure by drive motor, gearbox (reducer) assembly of deceleration motor, different application scenarios, projector using different miniature deceleration motor, in order to better meet the market demand, usually adopt customized technical parameters service, such as drive motor output speed, output power, rated voltage, gearbox deceleration transmission ratio, output torque and other technical parameters are customized development.
