Intelligent control system for power source for e.g. personal computer, has digital control unit adjusting output power based on infrared signal and selection signals to adjustment unit to change light brightness of LED-lighting chain

摘要

The system has a signal acquisition brightness control and adjustment unit (10) detecting an infrared signal and producing different brightness selection signals. A digital control unit of a power source (20) is attached to the brightness control and adjustment unit. The digital control unit adjusts output power according to the infrared signal and the brightness selection signals to the brightness control and adjustment unit to change light brightness of an LED lighting chain (3). A signal amplifier unit is integrated optionally with a dimmer (104) or an infrared sensor (102) in same chip.
