60W Smart LED Lighting


Smart Commercial Lighting

Commercial and industrial fixture manufacturers are under pressure to regularly update lighting systems with new technology and capabilities, but design and development times for those complex systems can be 18 months or more.

The RD-574 60W LED engine reference design is a turnkey solution that reduces development time for demanding dimming and multi-LED string control systems without compromising performance. The smart lighting platform features Fairchild PFC and LLC controllers and an Atmel microcontroller that enables mixed mode dimming and smart network connectivity. The solution is programmable for multiple dimming profiles and optimized for lighting in offices, hospitality, and industrial applications.


  • Can connect wireless IoT microcontrollers and networking software (DALI, ZigBee/ZLL, Wi-fi, and 0-10V interfaces)
  • High dimming performance down to 0.05%
  • Independent channel control with automatic LED string voltage detection and power adjustment
  • 24-48V wide LED voltage range
  • >85% driver efficiency
  • THD <10%
  • Form factor is ready for 60W fixture design-ins
