Lumileds Boosts Intensity of CoBs for Spotlights and Downlights

Lumileds today introduced three lines of CoBs: the LUXEON CX Plus CoB (Gen 2), LUXEON CX Plus CoB – High Density and LUXEON CX Plus CoB – High Density (Below BBL), drop-in upgrades for Lumileds and competing arrays. The second generation arrays feature industry leading performance and a 14% flux improvement vs. the previous generation. Delivered in a range of light emitting surfaces (LES) (4.5, 6, 12 and 14mm) and correlated color temperatures of 2700K to 5000K, the Gen 2 arrays provide excellent efficiency of above 140 lm/W at 3000 K 80 CRI or 122 lm/W at 3000 K 90 CRI.

The High Density version of LUXEON CX Plus CoB provides industry leading punch (center beam candle power) and is available in on-black body locus (BBL) coordinates for halogen-like illumination or below-BBL for ceramic metal halide-like illumination.

The LUXEON CX Plus CoB – High Density provides up to 1,150 lumens at 3000 K 90 CRI from the smallest LES of 4.5 mm. Flux is 10% higher than competing CoBs at 6 mm and 9 mm LES.

Offered in three LES (4.5, 6 and 9 mm) on 13.35x13.35 mm substrate, the arrays cover a range of color temperatures (2700 K to 5000 K) with a minimum of 80 CRI or 90 CRI and color control within 3-step or 2-step MacAdam ellipse.

For the Below-BBL versions, color temperature range is 2700 K to 4000 K at a minimum of 95 CRI with color control within 3-step or 2-step MacAdam ellipse.

"The below black body option is perfect for illuminating artwork, for instance, because the highest color fidelity combines with slightly more saturated colors for stunning results," said LP Liew, Product Manager of LUXEON CoBs.

All LUXEON arrays utilize a metal core PCB substrate that is more resistant to cracking during luminaire assembly. The low resistance of the MCPCB also provides superior removal of heat from the LED, leading to smaller heatsinks and more compact luminaires.
