Luminus launches Generation 4 high-density COBs with Robusto technology

Luminus Devices Inc of Sunnyvale, CA, USA – which designs and makes LEDs and solid-state technology (SST) light sources for illumination markets – has launched its next generation of high-lumen-density white COB arrays featuring Robusto technology, the latest enhancement to improve maximum operating temperature.

High-lumen-density parts are used in narrow-beam applications where center-beam candle power (CBCP) is the key metric. While this depends on the specific beam angle and power level, the high-lumen-density parts typically deliver at least twice the lumen density of standard parts. Higher-temperature operation means more luminaire design flexibility and lower potential cost with, for example, smaller, lighter heat sinks.

These Generation 4 high-lumen-density parts provide stable lumen output and color points with temperatures as high as Tc = 120⁰C. Robusto technology has the ability to enable higher drive currents while still delivering what is claimed to be exceptional lumen maintenance (L90>55k hrs) and remarkably stable color points.

The new line of COBs has what is said to be outstanding color quality, high lumen intensity, and the industry’s best flux and color stability over their operating life, all of which suits narrow-beam, high-CBCP applications in retail and shop lighting, hospitality lighting, architectural and specialty lighting.

“The new Generation 4 high-lumen-density parts offer the ultimate in COB flux density,” says David Davito, COB product line director, Illumination. “This is complemented by Robusto technology, which enables higher operating conditions while maintaining steady lumen maintenance and color stability,” he adds. “With Robusto technology, Luminus’ high-density COBs are able to provide customers with higher levels of CBCP, consistent color and flux over the life of the luminaire.”
