Luminus Releases latest High Density white COB arrays

News

New arrays feature Robusto technology to double the lumen density and provide stabie outputs at high temperatures

Luminus Devices is introducing its next generation for high lumen density, white COB arrays. Called Robusto technology, it features 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 two times or greater lumen density than 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 colour points with temperatures as high as Tc = 120degC.

Robusto technology has the ability to enable higher drive currents while still delivering exceptional lumen maintenance (L90>55k hrs.) and remarkably stable colour points. This line of COBs is said to hvae outstanding colour quality, high lumen intensity, and the industry’s best flux and colour stability over their operating life, all of which make them the preferred solution for narrow beam, high CBCP applications in retail and shop lighting, hospitality lighting, architectural and specialty lighting.

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