Abstract :
A wireless controllable LED dimming system with an android remote control is proposed. The whole system consists of a constant current LED driver based on buck converter with LM3409HV buck controller, a microcontroller with wireless transceiver and Android smartphone as remote control. The wireless control signal from Android remote control is sent and microcontroller is used to decode the control signal and generate PWM dimming signal to LED driver, and thus, to control the LED´s brightness. An android remote control application is developed and installed in an android smartphone. The experiment results show the energy efficiency of the proposed wireless controllable LED system.
