Lumileds Upgrades Luxeon chip-on-board LEDs
Lumileds has introduced a second generation of its Luxeon CoB (chip on board) Compact Range LEDs, featuring an efficacy and output boost of up to 16 percent over the previous generation arrays, according to the company
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, minimising design and system cost. The upgraded arrays also achieve a high centre beam candlepower (CBCP) or "˜punch'. At 1,500 lumens, the Luxeon CoB 209 reaches 76,000 candelas at a 10° beam angle.
"Customers currently using first generation Luxeon CoB Compact Range are also particularly excited about this upgrade because they 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 percent in efficacy," said Ivan Tsoi, product manager for Luxeon CoB Compact Range at Lumileds.
The performance boost, combined with the industry's lowest thermal resistance, leads to smaller heat sinks and more cost efficient lamps.
The new LEDs are offered in a wide range of colour temperatures (2200K to 5700K) and CRIs (80 and 90). The range is also available with Lumileds CrispWhite Technology designed to be used in fashion retail lighting. 100 percent of Luxeon CoB Compact Range arrays are hot tested at 85degC to ensure performance in real world operating conditions and to minimise additional testing.
