Future Lighting Solutions has come out a new white paper, which titled "Enabling LED-Based Recessed Downlight Applications," to provide guidelines for developing high-performance solid state downlights.

This paper elaborates the considerations and components for implementing LED-based downlight fixtures that satisfy to the market needs as well as ENERGY STAR® requirements, including light output, efficacy and longevity benchmarks.
 
Topics comprise of component selection, how to determine the corrected drive parameters, and the role of optical, thermal and power solutions in producing reliable solid state downlighting.
 
Examples provided utilize Philips Lumileds LUXEON® Rebel LEDs, NXP dimmable IC drivers, and Future Lighting Solutions simpleLED® light engines that accelerate time to market by providing LEDs, secondary optics and onboard connectors already mounted on circuit boards. The simpleLED off-the-shelf assemblies also include UL recognition that eliminates the need for a full in-system LED component investigation to obtain UL Listed status for new luminaires.

In conclusion, the paper provides a road map for implementing a Future-developed 4" and 6" reference design for recessed downlight systems.
