Lumileds drives LEDs at 1 A to produce 80 lumens
In comparison, high-flux LEDs from other suppliers produce only 2 to 5 lumens per package in white and comparable performance in color. In addition to white, the Luxeon III is available in blue, royal blue, green and cyan.
Lumileds says that the chip in Luxeon III package incorporates improvements in current-carrying capability, increasing the robustness of the device and allowing it to be driven at higher drive currents.
The new Luxeon LED also has a high lumen maintenance, retaining 70 percent of its brightness after 50,000 hours of operation at 700 mA and 50 percent at 20,000 hours when driven at 1000 mA.
The Luxeon III offers significant size, longevity and energy-saving benefits for products of all kinds, including task, orientation and architectural lighting, reading lights, flashlights, garden lighting, traffic signaling, edge-lit signs, and LCD backlights.
Lumileds also manufactures a 120-lumen product, the Luxeon V. The Luxeon III has been designed to combine high optical output with high lumen maintenance.
“Luxeon III is the result of direct feedback from both lighting designers and manufacturers who asked for a new LED with light output between the Luxeon and Luxeon V products to provide new design options," said Jason Posselt, director of product marketing for Lumileds Lighting.
“The optical and thermal characteristics of Luxeon III and the new 700 and 1000mA drive current limits, without sacrificing lumen maintenance, uniquely qualify Luxeon III for a wide range of applications.”
The Luxeon III Emitter and Luxeon III Star (mounted on FR4/aluminum PC Board) are immediately available in the Lambertian radiation pattern in white, royal blue, blue, green and cyan.
