| Abstract:This paper proposes a kind of designing scheme for LED intelligent lighting based on DALI bus in order to enhance the cost performance of the intelligent lighting system. The key technology lies in the designs of DALI control module and the dimming driving power supply. The System realizes DALI control function through applying Micro-control Unit(MCU), general analog circuits and digital circuits to instead of the expensive specialized DALI chip. Soft -switching technology has been applied in LED driving power supply which contains the interface of DALI and some kinds of sensors, combining emergency lighting function. PWM (Pulse Width Modulation) dimming and intelligent monitoring for LED lamp can be finished by the designed system. The prototyping system has been manufactured, and the relevant experimental results demonstrate the possibility of the scheme. |
