Luminus Devices has introduced its Hospitality COB Series. With LES sizes ranging from 6 to 22 millimeters and lumen output from 500 to 5000 lumens, the Luminus Hospitality COB series is a suitable choice for warm light with color rendering and two-step SDCM color control standard.
As LEDs have been adopted into indoor illumination applications over the past decade, the industry has reached impressive cost and energy-efficiency goals, but for Luminus the focus has always been on taking the quality of light to new heights. The Hospitality COB Series is specifically designed to deliver comfortable lighting scenes in hotels, restaurants, and other applications where warm, quality of light is essential.
What makes the Hospitality COB Series different from other warm light sources? Luminus engineers teamed up with global hospitality lighting customers to identify unique “xy chromaticity” targets just slightly below the black body locus (BBL) where the warm tint provides a comfortable environment for humans without any “greenish” tint that might be present with typical industry standard lights. Until now, the lighting industry has largely followed the CCT chromaticity “bins” defined by ANSI, which are centered on the BBL at nominal, warm CCTs of 2700K, 3000K, and 3500K. This means that half of the light sources will be above the BBL and half below, and those above will lean toward a greenish tint, which is extremely unattractive, especially on human skin. The 4000K ANSI color space is even centered slightly above the BBL, which further raises the possibility of your standard LEDs from other suppliers producing that undesirable green tint.
The Luminus Hospitality COB Series also leverages phosphor and chip combinations to deliver 90 or 95 CRI minimum, high R9 values, and TM-30-15 and TM-30-18 specifications.
