With the LUXEON CoB Core Range (Gen 3), luminaire designers can enjoy 10% higher efficacy at constant flux compared to previous generations.
All LUXEON CoB developments are engineered to produce the highest flux with the smallest light emitting surface (LES). "This performance upgrade is the result of significant improvements in both die development and our industry-leading phosphor solutions that give us industry leading performance," said Eric Senders, Product Line Director for the LUXEON CoB Family.
The Gen 3 LUXEON CoB upgrade spans the company’s full range of products from the smallest LES of 6.5 mm (LUXEON CoB 1202s), which delivers cost effective spotlights, to an LES of 23 mm (LUXEON CoB 1216), for efficient replacement of 100-150W HIDs in indoor or outdoor applications. The LUXEON CoB Core Range is offered over the widest range of color temperatures (2200K to 5700K) and CRIs (70, 80 or 90).
Lumileds also attributes the performance gains to the device's low thermal resistance substrate, which is claimed to be up to four times lower than other commercial products. The lowest thermal resistance enables smaller heat sinks and optics, delivering lower system cost. All of LUXEON CoB Core Range (Gen 3) arrays are hot tested at 85°C to ensure performance in real world operating conditions and to minimize additional testing.
