Philips Lumileds announces Luxeon Q LED, pushes efficacy

Philips Lumileds has announced the Luxeon Q family of phosphor-converted white LEDs in a 3.5×3.5-mm package, based on the blue die that the company announced last February. The company said that the epitaxy technology combined with light extraction and conversion enhancements at the die, phosphor, and package level deliver industry-leading efficacy for solid-state lighting (SSL) products. The Luxeon Q family spans the range of 2700K to 5700K CCTs. The warmer-white LEDs have a CRI of 80 whereas the members with CCT of 4000K and above have a CRI of 70. Lumileds will offer the LEDs in 3- and 5-step MacAdam ellipse bins. Still, the primary focus of the new LED is more lumens per dollar through high efficacy.
