Rambus lighting tech illuminates Cooper’s new LED-based luminaire

This entry was posted on Tuesday, December 16th, 2014.

Eaton’s Cooper Lighting division recently introduced the Portfolio Surface-Mount, an LED-based luminaire that incorporates the company’s WaveStream™ planar light-guide technology.

As Maury Wright of LEDs Magazine explains, the fixture surface mounts to standard or high ceilings – including applications with little or no plenum place, in pendant and other configurations.

“Cooper [has] been proliferating WaveStream based on light-guide technology licensed from Rambus,” said Wright.

“The technology relies on LEDs to edge light the optical guide that embeds miniature beam-control elements that Cooper calls AccuAim optics. In simple terms, the planar guide produces uniform diffuse light with minimal glare.”

Indeed, WaveStream LED fixtures feature waveguides patterned with MicroLens® optics to deliver a precisely controlled light output. According to Wright, Cooper has used WaveStream in a number of ceiling troffer-style fixture, parking garage fixtures and downlights.

“Given the variety of WaveStream-based products, it comes as no surprise that the technology has come to a round solid-state lighting (SSL) flush-mount form factor,” says Wright. “The product mounts directly to a junction box. Cooper offers models ranging from 4500–9000 lm, 4000K–4000K CCT and 80 or 90 CRI.”

It should be noted that the Portfolio Surface-Mount also supports smart-lighting installations with a variety of control options. To be sure, the standard LED driver includes 0-10V dimming support and works with trailing-edge phase-cut dimmers such as those designed for electronic-low-voltage (ELV) products. Further, optional DALI (digital addressable lighting interface) can be added.
