High-power LEDs produce more light
Philips Lumileds is claiming new performance records for high-power white LEDs.
Philips Lumileds is claiming new performance records for high-power white LEDs In tests, Philips Lumileds 1 x 1mm2 chip-based white LEDs, operating at just 350mA, delivered 136 lumen for a light source efficiency of 115 lumen/W at a correlated-colour-temperature (CCT) of 4685K

Bright showing from long-life LEDs
The Luxeon III is a new high-power 100kh-life LED that generates typical light output of 65 and 80 lumen from a single emitter at 700 and 1000mA operation, respectively.
RGB LED backlight is ready to use
The Luxeon DCC is billed as the first fully assembled LED-based RGB light source for use as an alternative to cold cathode fluorescent lamps in LCD backlights.
At 2000mA, Philips Lumileds white LEDs delivered 502 lumen at a corresponding 61 lumen/W.
These LEDs are the first high-power LEDs to break through the 100 lumen/W mark and demonstrate the real potential of solid-state lighting technology.
Philips Lumileds, the creator of the 350mA high-power LED, continues its innovation by developing more powerful LEDs capable of long life when driven at 1000, 2000mA and higher.
This innovation improves the light efficacy and the light quality, all while offering the lower cost required by many applications.
Notable in the performance numbers is the CCT which is significantly lower than those typically reported.
These results clearly demonstrate Philips Lumileds' progress in both light output and light quality.
Philips Lumileds achieved the record results for white LEDs by combining several new and innovative technologies it has developed.
The first devices using these technologies will be introduced in a new generation of products during this quarter.
These new technologies will continue to proliferate in new, and existing, products throughout the next 12-18 months.
Philips Lumileds breakthroughs in epitaxy, device physics, phosphor, and packaging technologies are critical to delivering the performance required of LEDs as they continue their growth into a preferred light source.
The light output performance announced today and available to the industry in the near future, is 17 times greater at the same power than was available in 1999 when Philips Lumileds introduced the first high-power LED.
While performance numbers continue to increase for low power LEDs, operating at lower currents such as 20mA, high-power LEDs are required to deliver the quality and quantity of light required for today's and tomorrow's lighting applications.
