by Rebecca Walker — March 25, 2011—Philips Lumileds, an LED technology and market leader, continues to expand its Luxeon LED portfolio with its first high voltage emitter, Luxeon H.
The new emitters are driven directly with rectified AC voltage rather than constant DC current. This high voltage architecture maximizes space for additional thermal management, permitting an increase in the thermal limit for even the smallest bulbs. The 50 Volt LUXEON H flexibly supports both 110V and 240V solutions.
Designed to meet the demands of space constrained retrofit bulbs, Luxeon H emitters deliver industry leading thermal performance and reliability, according to the company, as well as high quality, warm white light. Two color temperatures are available, 2700K and 3000K, with typical CRIs of 83. Typical flux is 84 lumens and 90 lumens respectively for the two correlated color temperatures. The new LUXEON H emitters are identical in footprint to the compact LUXEON Rebel and LUXEON Rebel ES LEDs further simplifying implementation.
Initial uses of LUXEON H are expected in the retrofit bulb market where form factors for the bulbs are already defined and space is at a premium, particularly for the smallest bulb types ranging from the candelabra to the intermediate Edison, E10-E17 types.
