LED maker Lumileds of San Jose, CA, USA has launched its second-generation LUXEON CoB Compact Range of LEDs, which feature an efficacy and output boost of up to 16% over its previous-generation arrays. Lumileds says that the new product line reinforces its position in chip-on-board technology by enabling cost-effective solid-state PAR, GU-10 and MR-16 lamps for retail, hospitality and home lighting applications.
Due to the common light-emitting surface (LES) of 6.5mm across the LUXEON CoB Compact Range Gen 2 LEDs, different power range directional lamps such as a 35W-equivalent and a 50W-equivalent MR-16 lamp can use the same optic, minimizing design and system cost. The upgraded arrays also achieve what is claimed to be unsurpassed center-beam candlepower (CBCP) or 'punch'. At 1500 lumens, the LUXEON CoB 209 reaches 76,000 candelas at a 10° beam angle.
"Customers currently using first-generation LUXEON CoB Compact Range can replace a Gen 1 Compact Range 109 with a Gen 2 Compact Range 205 to attain the same performance at a significantly lower cost, or they can replace a Gen 1 Compact Range 105 with a Gen 2 Compact Range 205 and boost output by 16% in efficacy," says Ivan Tsoi, product manager for the LUXEON CoB Compact Range. The performance boost, combined with what is claimed to be the industry's lowest thermal resistance, leads to smaller heat-sinks and more cost-efficient lamps.
LUXEON CoB Compact Range LEDs are offered in what is claimed to be the industry's widest range of color temperatures (CCT of 2200-5700K) and color rendering indexes (CRIs of 80 and 90). The range is also available with Lumileds' CrispWhite Technology (designed to be used in fashion retail lighting to reveal the richest whites, most vibrant reds and to make all colors pop). All LUXEON CoB Compact Range arrays are hot tested at 85°C to ensure performance in real-world operating conditions and to minimize additional testing.
Also, with the wide availability of compatible holders, optics and drivers, time to market of spotlights and directional lamps is now faster, says the firm.
