Lumichip, a leading developer of LED packaging solutions and light engines, has designed-in Cambridge Nanotherm’s thermal management technology for LEDs. Thorough tests by Lumichip revealed Cambridge Nanotherm’s technology to have extraordinarily high levels of thermal performance, well beyond that of comparable solutions and approaching the thermal performance of exotic ceramic materials such as AIN (aluminium nitride). Lumichip has therefore selected Nanotherm’s technology as the basis for a series of technology-leading COB LED modules for UVA applications.
Lumichip has outlined its test results in a free-to-download whitepaper, available today.
The tests involved a chainable 75W module with an array of 63 UVA chips in a 7×9 format. By selecting Cambridge Nanotherm’s technology, Lumichip was able to achieve a heat dissipation density of 20 W/cm2 with a thermal efficiency of 34% – a level well above the best generally seen in the UV industry.
“Outside of the context of this whitepaper we ran tests on a variety of thermal management solutions,” stated Shane O’Farrell, CEO, Lumichip. “Cambridge Nanotherm’s was categorically the best we encountered. I can’t think of any other material, at this price point, that could perform this well in such a thermally-aggressive environment.”
“As a result of the tests we’ve rolled out a full series of high power COB LED modules for UVA wavelengths 365 to 405nm based on the Nanotherm platform. The whitepaper was written to demonstrate the objective evidence of how much better Nanotherm’s solution, and hence our product, is over the competition.”
“We’re immensely proud to be able to count Lumichip amongst our customers,” offered Ralph Weir, CEO, Cambridge Nanotherm. “The UV market has some especially demanding thermal environments and our technology is extremely well suited to address them. UV designers are under especially intense pressure to improve the thermal performance of their products. Offsetting the high amount of heat that UV LEDs generate can produce huge benefits in terms of efficiency and lifespan, and using Nanotherm allows designers to lower costs by using aluminium based nanoceramic substrates rather than being forced to move to high cost AIN.”
“In combination with our thermal management technology Lumichip is offering a class-leading UV LED product range. The possibilities it allows are endless, from smaller, higher intensity and longer-lasting device classes, to efficiency gains, to cost reductions in the overall product.”
