Solid-state lighting is important in the general illumination market because of the recent improvements in phosphor-based white LED technology. Cypress’ EZ-Color™ and PowerPSoC® family of devices can be used to build light engines using LEDs for a variety of applications including general illumination. This application note explains the color quality parameters for white light sources and describes a tool developed by Cypress to estimate Color Rendering Index (CRI) of a LED luminaire. This application note also describes how Cypress's lighting solutions can control LEDs and meet luminaire specifications set by compliance agencies like Energy Star.
