The global light engine technology major Lumileds on Tuesday announced the addition of three new products to what it described as its successful LUXEON CoB core range for high lumen output applications – streetlights, stadium lights and high bay and low bay fixtures.
“We now have the ability to address not only 40W and 50W applications but up to 100W and 120W applications with these high lumen packages, at the same high efficacy as our LUXEON CoB Core Range (Gen 3) products,” said Eric Senders, product line director for the LUXEON CoB family in a press statement.
According to Senders, the high lumen extension of the LUXEON CoB core range (Gen 3) features light emitting surfaces (LES) of 23, 29 and 32-mm, nominal fluxes of 8,800, 11,000 and 16,000-lm at drive currents of 1.2, 2.1 and 2.2-A, with efficacy up to 161lm/W. The arrays are offered over a colour temperature range of 2700K to 5700K and CRI of 70, 80 or 90, with an efficient 70 CRI solution in warmer 3000K. These are applied for outdoor lighting as well as a special colour requirement for studios and stadiums where cool colour temperatures and high (>90) CRI are required.
The CoBs are mounted on square Metal Core PCBs (MCPCBs), which he said, provide the industry’s lowest thermal resistance, enabling smaller heat sinks and optics for lower overall system cost. “Feedback from many CoB customers indicates that heat sinks alone make up a substantial portion of system cost. By keeping the LES as small as possible and having a low thermal resistance substrate, a smaller heat sink can be used and a good portion of the cost has been removed from the system.”
The LUXEON CoB Core Range (Gen 3) CoBs are compatible with an existing ecosystem of optic, drivers and holders that enable faster time to market of outdoor streetlights, high bay & low bay fixtures, Senders added.
