4.2 Blower Fan

Blower fan is designed for cooling the lamp tip and lamp burner. The speed of blower fan is controlled and

monitoring by MCU.

4.3 Rear Fan

Rear fan is designed for cooling the whole system except tip and burner of lamp. The speed of rear fan is controlled

and monitoring by MCU.

4.4 Temperature Sensor

There are three temperature sensors built on the system. One is seated at fresh air intake area. One is seated on

DMD heat-sink. And the other one is near by the Lamp Box. The sensor is binary junction diode, and there is chopping

bias current on it. MCU will do polling for each sensor and fan speed, and execute cooling V-T curve control program in

order to feed the environment situation changing requirement.

4.5 Fan Controller

The fan driver device consists of I2C interface, thermal sensor interface, fan current output

interface, and the tachometer interface. MCU access fan driver device by I2C interface. Thermal

sensor interface is analog small sensitive signal. The temperature measurement principle is

calculating the biasing current of diode to figure out the temperature parameter of the diode.

Chapter 5 Power Supply Circuit Operation Theory

5.1 Overview

The power supply unit includes EMI board, PFC board, DC/DC board (built on Fan board), and

Ballast board.

The EMI board has EMI filter circuit to reduce EMC noise coupling to AC line. The PFC board

circuit supply AC line power factor correction function. DC/DC board converts primary voltage to
secondary DC low level voltage for system using. And Ballast board generates the lamp ignition high
voltage to ignite the lamp, maintains the stable power consumption of lamp, and synchronizes the
lamp sequence with DLP color index sequence.
