March 29, 2007, San Jose, CA--Philips Lumileds has announced immediate availability of LUXEON Rebel power LEDs with new packaging technology that dramatically reduces the size of the LED and enables entirely new approaches to solid-state lighting design. Engineered for operation between 350 mA and 1000 mA, LUXEON Rebel is the first power LED to offer guaranteed minimum performance, which enables greater design and manufacturing consistency and allows customers to purchase the light output performance appropriate for each application.
For applications requiring high efficacy, cool-white LUXEON Rebel can exceed 70 lumens per Watt at 350 mA. When total light output needs to be maximized, the new device delivers more than 160 lumens at higher drive currents. Warm-white, neutral-white and cool-white color temperatures in addition to standard indium gallium nitride (InGaN) and aluminum indium gallium phosphide (AlInGaP) colors provide the most complete color palette for lighting designers and specifiers.
LUXEON Rebel also establishes new power LED benchmarks for size, engineering parameters, reliability and lifetime. At 3 mm x 4.5 mm, the foot print area is 75% smaller than other surface mount power LEDs. The small footprint and low profile, 2.1 mm, enable significantly reduced color mixing and diffusion depths so that luminaire designs can be as much as much as 50% slimmer than with conventional power LEDs. The small size also reduces the amount of PCB required.
LUXEON Rebel is the first power LED from Philips Lumileds to offer white LEDs in warm, neutral and cool-white with typical Correlated Color Temperatures (CCTs) of 3000K, 4100K and 6500K respectively. The LUXEON Rebel white binning structure includes a CCT range from 2670K to 3500K for warm-white, 3500K to 4500K for neutral-white, and 4500K to 10000K for cool-white.
Sampling of the warm-white and neutral-white products begins immediately with volume production later this year. For lighting designers, the addition of a neutral-white range makes it easier to appropriately target the color temperature characteristics for many applications. The company's patented conformal coating process minimizes CCT variation and maximizes color uniformity.
"LUXEON Rebel takes advantage of our latest chip, phosphor and packaging technologies to accelerate the use of LEDs in a wide range of lighting applications, particularly residential and other 'white lighting' applications for which LED options have been limited," said David Eastley, Product Manager. "We also recognize that there is a technical communication gap between the semiconductor and lighting communities so we are taking the lead in defining new references for reliability—lumen maintenance and lifetime—and tools that allow reliability to be analyzed based on temperature and drive current variations. These measures along with our flux-differentiation, guaranteed performance and improved white color temperature selection make it easier than ever to create lighting solutions."
