One solution of the light source based on LED with radio-control provided with Zigbee-compatible microcontroller CC2530

This paper describes one solution of LED based luminaire control. The device is powered by 230V/50Hz AC network using 20W flyback regulator with optimized PFC, which is an advantage over common CLF lamps. Current through 4 strips of LED diodes (red, green, blue and white) is controlled by 4 independent buck regulators using 4 PWM signals from Zigbee-compatible microcontroller CC2530. This way a full control over light intensity and spectral content is achieved, as well as compatibility with existing remote controller from OBLO home automation system.
