Luminus Devices, Inc. has released its fourth generation chip-on-board LED technology (Gen 4) that will open new opportunities in retail lighting as well as a wide range of indoor and outdoor lighting applications.
Gen 4 COB technology
It is possible for an LED to deliver the output and punch of a 70 Watt ceramic metal halide lamp
Luminus Gen 4 COB technology combines significant improvements in efficacy, flux density, high maximum drive current, and high-temperature capability to enable breakthrough changes in form factor for luminaire makers, for example, it is possible for an LED to deliver the output and punch of a 70 Watt ceramic metal halide lamp in an identical form factor.
Luminus has eliminated the barriers that had required LED luminaires with comparable center beam candlepower to be larger than the incumbent CMH technology.
AccuWhite™ and Sensus™
“We’ve seen LED replacements for lower wattage CMH lamps, but we’re finally able to displace the 70W lamp which has been the go-to choice of many retail lighting designers when they need a narrow beam spot to make the merchandise sparkle,” said Tom Jory, VP of Illumination at Luminus.
Tom Jory adds, “Only Luminus Gen 4 COBs enable small form factor fixtures with the punch of 70 Watt CMH in combination with our unique spectral tuning technologies AccuWhite™ and Sensus™.”
reliability and longevity
Unique to Luminus Gen 4 COBs are the very high operating temperature of 120°C and the capability to be overdriven at 3x the nominal current.
The advances in this generation of LED technology enable extended operating conditions while maintaining color performance over time and temperature with reliability and longevity.
