Lumileds LUXEON CX Plus Chip-on-Board (CoB) Emitters

New CoB LEDs offer higher intensity in spotlights and downlights.

Lumileds LUXEON CX Plus Chip-on-Board emitters extends its range of integrated CoB emitters, launching products which offer a higher light output than earlier products and stronger ‘punch’, giving high brightness from a small Light-Emitting Surface (LES).

The LUXEON CX Plus CoB (Gen 2) arrays feature a 14% flux improvement over the previous generation of CX Plus CoB products. The Gen 2 LEDs are supplied in a choice of LES options: 4.5mm, 6mm, 12mm or 14mm diameter. Correlated color temperature options range from 2700K to 5000K. Efficacy is higher than 140lm/W at 3000K for the 80 CRI version, and 122lm/W for the 90 CRI version.

Lumileds has also introduced two high-density versions of the LUXEON CX Plus CoB. The LUXEON CX Plus CoB – High Density and LUXEON CX Plus CoB – High Density (Below BBL) products are drop-in upgrades for existing arrays from Lumileds or competing manufacturers.

The Lumileds High Density version of the LUXEON CX Plus CoB provides industry leading punch (measured as center beam candle power), and is available in on-Blackbody Locus (BBL) coordinates for halogen-like illumination, or below-BBL for ceramic metal halide-like illumination.

For high punch, the LUXEON CX Plus CoB – High Density provides output of up to 1,150lm at 3000K in the 90 CRI version from the smallest LES of 4.5mm. Flux is 10% higher than competing CoBs from the versions with an LES of 6mm or 9mm.

Offered in three LES options - 4.5mm, 6mm or 9mm - and mounted on a 13.35mm x 13.35mm substrate, the Lumileds arrays cover a range of color temperatures between 2700K and 5000K with a minimum of 80 or 90 CRI. Color control is maintained within a 3- or 2-step MacAdam ellipse.

For the below-BBL versions, the color-temperature range is 2700K to 4000K at a minimum of 95 CRI with color control within a 3- or 2-step MacAdam ellipse. This below-BBL option is ideal for illuminating artwork, because it combines very high color fidelity with slightly saturated colors to produce a stunning visual effect.
