Lumileds has introduced its third generation of Chip on Board (CoB) arrays, the LUXEON Core Range (Gen 3), extending its market leadership in the CoB space with a breakthrough in efficacy. With the LUXEON CoB Core Range (Gen 3), luminaire designers can enjoy 10 percent 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 its improved performance to its low thermal resistance substrate, which is up to 4X lower than other commercial products. The lowest thermal resistance enables smaller heat sinks and optics, delivering lower system cost. 100 percent 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.
For ease of upgrade, the LUXEON CoB Core Range (Gen 3) products are fully compatible with the LUXEON CoB Gen 1 and Gen 2 arrays. The company’s ecosystem of compatible drivers, optics and holders help speed the time-to-market of all directional lamps.
