Lamp Control
ON/OFF control of the lamp is carried out by High/Low of the LAMP_POWER
signal mapping in the GPIO of IC3502.The brightness setup and the lighting
status of Normal/ECO are supervised and controlled by the serial communication
function of IC3502.
The LAMP_POWER signal is guarded by the hardware functions of the relevant
signals of the lamp cover status, bimetal, FAN stoppage, and MAIN_POWER.
When all the conditions are found normal, lamp lighting control becomes
possible.
Compared with newly specified model, lamp power setting can be made more
precisely and lower.
