Lumileds CoB arrayPhilips Lumileds introduced the LUXEON CoB (Chip-on-Board) portfolio. The family can deliver up to 6000 lumens and reaches efficacies of up to 120 lm/W (hot tested) for bright white 80 CRI lights. This makes the arrays appropriate for high-lumen downlights, spotlights and directional lamps. Due to its uniform, small light-emitting surface (LES) and desirable efficiency, the company asserts designers can reduce optical solutions expenses and still achieve higher center-beam candle power (CBCP). In commercial applications such as downlights, uniformity and rotational symmetry are particularly important performance metrics. The LUXEON CoB arrays are hot tested and specified at 85°C and use a metal-core printed circuit board (MCPCB) solution. This platform enables better reliability, thermal heat dissipation and handling in LED assembly.  Offered initially in four versions with an LES of 9, 13 or 15 mm, the LUXEON CoB arrays deliver up to 6000 lm output.
