Newly uprated LEDs have been added to Lumileds’ two most powerful product families, the Luxeon C and CZ, for greater flux and radiometric wattage, as well as improved beam distribution. The PC amber LEDs, for example, have 17% greater flux. Lumileds product marketing manager LP Liew says “The Luxeon colour lines are known for having the greatest colour selection, and now they provide even higher luminous output so fixtures will require fewer LEDs to achieve their target brightness in a smaller overall footprint”.
The Luxeon C and CZ ranges include both monochromatic and phosphor-converted LEDs. High-brightness LEDs in colours serve a smaller overall market than phosphor-converted white LEDs, but there are very important applications for colour LEDs with very high flux—such as emergency vehicles and facade lighting.
