Bridgelux has expanded its RS LED Array family with new models that reach 5600 lm in warm white and 8000 lm in cool white, and targets market segments such as retail lighting and street lights.

Bridgelux introduced the RS family of LED arrays a year ago, and is now adding products with greater lumen output for solid-state-lighting (SSL) applications. The company has enhanced versions of existing products that boost output 20% while reducing the cost per lumen by 30%, and the company introduced new products that offer light output in the 5600-to-8000-lm range.

The RS family targets applications that demand high-lumen sources. VP of Global Marketing Jason Posselt asserts that customer demand drove the company to create the RS family in which the company packages an array of emitters under a single lens. Target applications include retail-store lighting and LED street lights.

Bridgelux is offering the new members of the RS family in 2700K, 3000K, 4000K, and 5600K color temperatures. The LEDs have a CRI of 82, although the 2700K products can be optionally specified with a 90 CRI. The company is offering 3-step MacAdam ellipse binning.

The RS announcement covers both what are essentially enhancements to existing products as well as some new arrays. The company has boosted the light output of existing RS family members by 20% -- for instance taking what was a 3000-lm warm-white array to 3600 lm. According to Posselt, a combination of improvements in chip, epitaxy and packaging yielded the increased output and a 30% reduction in cost per lumen.
