This solution is based on UPD78F9222 to achieve the adjustment of fluorescent lamps. The adjustment supports both manual and infrared methods, and can provide protection in the event of underpressure or overpressure. The automatic switch can also be set by software.
Dimmer function:
1. Wireless stepless dimming (infrared remote control)
2. Overvoltage and undervoltage protection
3. Constant power protection (according to customer requirements)
4. Support manual and infrared remote control 5. Support mainstream fluorescent lamps on the market
Hardware structure diagram:
Advantages of UPD78F9222 fluorescent lamp dimmer solution:
Design advantages:
1. Wireless stepless dimming (infrared remote control)
2. Energy consumption is half of incandescent lamps
3. Automatic switching schedule can be set through software, flexible operation
Application advantages:
1. Timing programming
2. Overpressure and underpressure protection
