New lighting possibilities with Luxeon K2 LEDs

Philips Lumileds announce availability of warm-white and neutral-white Luxeon K2 emitters as well as a Luxeon K2 Star part that can be specified with any standard white emitter.

The new white colours have typical correlated colour temperatures (CCT) of 3000K and 4100K and a colour rendering index (CRI) of 80 and 75 respectively.

The CCT range for Luxeon K2 now extends from 2670K to 10,000K and a new finer colour bin structure allows for better overall selection.

Unlike most power LEDs that are limited to 700mA, Luxeon K2 warm white and neutral white LEDs can be run up to 1500mA and a junction temperature of 150degC.

The new warm-white and neutral white can deliver more than 130lm and 140lm respectively.

Luxeon K2 delivers more usable light at virtually any drive current and junction temperature condition.

"With the increases in light output performance and efficacy, there is expanding demand for power LEDs that deliver the quality of light required for general lighting applications," said Steve Landau, Director of Marketing Communications.

"Designers of residential applications, such as recessed can lights need uniformity, high colour rendering and a warm white colour temperature at 3000K.

In many retail and commercial applications, a cooler temperature of 4100K is desired".

"With the new binning and phosphor technologies in Luxeon K2, the needs of lighting designers in both markets can be addressed".

Lighting designers consider several critical "quality of light" factors when evaluating white LEDs: colour temperature (CCT), colour rendering (CRI) and colour uniformity are three of the most important.

The new Luxeon K2 parts address CCT and CRI and Philips Lumileds phosphor expertise and technologies ensure the highest degree of colour uniformity resulting in white LEDs that are as much as 7 times more uniform than other white power LEDs.

Luxeon K2 Star, like the configuration already available in other Luxeon product families, consists of a white Luxeon K2 emitter mounted onto a metal core pc board (MCPCB).

This configuration allows for rapid prototyping and production in a wide range of applications without the need to create custom level 2 boards.

Luxeon Star products have been an industry standard for many years and been the configuration of choice for everything from architectural and entertainment lighting to emergency and portable lighting.

Complete product information is available on the company's website and in the Luxeon K2 datasheet also available online.

Luxeon K2 warm-white and neutral-white power LEDs are in-stock and available for immediate delivery from Future Electronics.

Luxeon K2 Star is stocked in limited quantities and interested parties should contact Future Electronics with their specific needs.
