Lumileds addresses colour mixing with equal-focus LEDs

Lumileds has tackled colour fringing in LED lighting with a range of LEDs that with matched optical centres regardless of wavelength. The family of devices is called Luxeon C Colors, and is aimed at stage and television lighting, as well as architectural lighting. “We’ve solved the problems of beam halos and mismatched, un-mixed colour by designing our platform to offer multiple colours with a single focal length,” said Lumileds product manager David Cosenza. When secondary optics are applied, the consistent focal length provides matched emission patterns, smoothing mixing.
