High-power LEDs come
in smaller packages
Power LEDs feature novel packaging technology that dramatically reduces the size of the LED and enables entirely new approaches to solid-state lighting design
Available now from Philips Lumileds, Luxeon Rebel power LEDs feature novel 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 and 1000mA, Luxeon Rebel is the first power LED to offer guaranteed minimum performance.

Power LEDs offer more white options
Expanded range of white emitters means the Luxeon K2 series is now available with correlated colour temperatures from 2670 to 10,000K
Minimum performance specifications enable greater design and manufacturing consistency and allow customers to purchase the light output performance appropriate for each application.
For applications requiring high efficacy, cool-white Luxeon Rebel can exceed 70 lumen/W at 350mA.
When total light output needs to be maximised, Luxeon Rebel delivers more than 160 lumen at higher drive currents.
Warm-white, neutral-white and cool-white colour temperatures in addition to standard InGaN and AlInGaP colours provide the most complete colour palette for lighting designers and specifiers.
Luxeon Rebel establishes new power LED benchmarks for size, engineering parameters, reliability and lifetime.

Luxeon Rebel is just 3 x 4.5mm with a foot print area 75% smaller than other surface mount power LEDs.
Its light output and efficacy performance from a 1mm2 chip make it the clear leader in lumens per unit area, lumens per watt and lumens per dollar.
The small footprint and low profile, just 2.1mm, enable significantly reduced colour 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 so that manufacturing costs may be lowered.
Although small, Luxeon Rebel is extremely robust.
The ceramic based package is designed to withstand high heat with a maximum junction temperature of 150C and it is the first power LED for lighting to be rated for unlimited shelf life further simplifying inventory management and manufacturing.
Luxeon Rebel is the first power LED from Philips Lumileds to offer white LEDs in warm, neutral and cool-white with typical correlated colour temperatures (CCTs) of 3000, 4100 and 6500K, respectively.
The Luxeon Rebel white binning structure includes a CCT range from 2670 to 3500K for warm-white, 3500 to 4500K for neutral-white, and 4500 to 10,000K 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 colour temperature characteristics for many applications.
The company's patented conformal coating process minimises CCT variation and maximises colour uniformity.
'Luxeon Rebel will cause a rapid change in solid-state lighting design', said David Eastley, Product Manager.
'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'.
'We also recognise 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 analysed based on temperature and drive current variations'.
'These measures along with our flux-differentiation, guaranteed performance and improved white colour temperature selection make it easier than ever to create lighting solutions'.
Luxeon Rebel has been prepositioned worldwide with Future Lighting Solutions, a division of Future Electronics for immediate availability.
In addition to the stocking of product, certified solutions partners in the Luxeon Lighting Network have already developed optics for Luxeon Rebel.
