SAN JOSE, Calif. — Chips on Board LED ArraysLumileds has added three new models to its LUXEON CoB Core Range of LED arrays.

The devices satisfy high-lumen output applications such as streetlights, stadium lights and high-bay and low-bay fixtures. The high-lumen extension of the LUXEON CoB Core Range features light emitting surfaces 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, plus efficacy up to 161 lm/W. The arrays are offered over a color temperature range of 2700 to 5700 K and a CRI of 70, 80 or 90, with an efficient 70-CRI solution in warmer 3000 K for outdoor lighting as well as a special color requirement for studios and stadiums where cool color temperatures and high CRI are required.

The chips on board are mounted on square metal core PCBs which provide the industry’s lowest thermal resistance, enabling smaller heat sinks and optics for lower overall system cost.
