Lumileds’ LUXEON MultiColor Module 2.5W in 5050-footprint PLCC package with no crosstalk between RGB and white LEDs

Lumileds LLC of San Jose, CA, USA has launched the LUXEON MultiColor Module 2.5W, a compact RGBW module that produces what is claimed to be leading flux and achieves exact color points in architectural and general outdoor lighting applications.

The 4-in-1 module simplifies system design by combining red, green, blue and white emitters in a compact 5050-footprint PLCC package. “We designed a barrier between the color and white emitter to eliminate the problem of crosstalk [when a direct LED excites the phosphor in a neighboring white LED, altering the emitted color], allowing designers to consistently achieve the exact color point they are targeting,” says product line director Jennifer Holland.

Typical flux of the LUXEON MultiColor Module 2.5W is 18lm (red), 38lm (green), 15lm (blue) and 53lm (white) at an injection current of 120mA. The emitter may be driven at up to 240mA to achieve what is claimed to be breakthrough lumen output. The single-emitter approach enables seamless color mixing without the shadowing associated with combining emitters of differing heights. The module especially shines in space-constrained applications, including linear architectural designs where four emitters require double the footprint of a single emitter.

Benchmark sulfur testing against the leading competitor revealed nearly twice the flux loss relative to the LUXEON MultiColor Module 2.5W, Lumileds claims. A far simpler solder pad layout also ensures precise contact and streamlines the assembly process.

The colors in the LUXEON MultiColor Module 2.5W can be individually or separately controlled for maximum flexibility in lighting design. An additional convenience of the module’s 5050 footprint is compatibility with industry optics to achieve different beam angles and intensities. Applications include outdoor facade lighting, architectural lighting, signage and any indoor applications with aggressive environments, from industrial plants to swimming pools.
