New LUXEON H LED: High Voltage LED Uses Rectified AC and Eliminates Need for DC Electronic Driver

Philips Lumileds, a 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.

Features:
• High voltage architecture maximizes space for thermal management
• Requires only a bridge rectifier and resistor, no DC driver
• ANSI compliant binning at CCTs of 2700K and 3000K
• Exceptional color stability over temperature and color current
• 50 V emitter supports 110V and 230V solutions
• Exceeds ENERGY STAR lumen maintenance requirements

Benefits:
• Simplified solution for space constrained implementations
• Lower system costs
• High quality of light
• Exceptional color stability at temperature for real-world application performance and reliability
• High efficacy for sustainable lighting design
• Complete optical, electrical and mechanical design resources help you get to market faster

Designed to meet the demands of space constrained retrofit bulbs, LUXEON H emitters deliver industry leading thermal performance and reliability 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.

“Our thin film flip chip technology allows us to continue to develop innovative solutions, like the multijunction die in LUXEON H, for the illumination market,” said Frank Harder, VP of Product Marketing for LUXEON. “The base of some bulbs is so small that it’s impossible to fit both an electronic driver and a heatsink in the space. LUXEON H only requires a bridge rectifier and a resistor, both of which are very small, and the remaining space can be used for thermal management. And, because we don’t use direct red die like most other HV solutions, LUXEON H offers consistent, stable color from the instant the LED is powered and maintains its color through its lifetime.”

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—especially so for the smallest bulb types ranging from the candelabra to the intermediate Edison, E10-E17 types. Philips Lumileds expects new solutions using LUXEON H to come to market during the second quarter of the year.

LUXEON H is in volume production and is available with standard lead times from Future Lighting Solutions. More information can be found at both Philips Lumileds’ website from Future Lighting Solutions or by contacting a local account manager.

Philips Lumileds continues to expand its LUXEON portfolio for the illumination market. LUXEON H joins the recently released LUXEON S, the first product with Freedom From Binning, and LUXEON Rebel and LUXEON Rebel ES, the most widely used power LEDs, to form a complete offering to the lighting community.
