Luminus launches multi-color LEDs for entertainment and architectural applications

Luminus Devices Inc of Billerica, MA, USA is sampling two new PhlatLight LED modules, for volume shipment from second-quarter 2009. The four-color CBM-380-RGBW and three-color CBM-290-RGB modules are designed to enable next-generation solid-state lighting fixtures for entertainment and architectural lighting applications that require ultra-high lumens and dynamic color-changing.

Based on the PhlatLight (Photonic Lattice) LED large-chip architecture, the firm claims that the new modules are the industry’s first multi-color LEDs with individually controllable color channels that can deliver light levels exceeding 2500 total lumens from a compact 6mm x 8mm optical footprint.

“The PhlatLight LED large-chip architecture shatters the current brightness limitations of solid-state lighting for the entertainment and architectural markets,” says Dave Sciabica, general manager of Luminus Devices' Lighting Business Group. “For the first time, fixture manufacturers can provide lighting designers intense high-quality, well-mixed digital light without the annoying color shadows that result from using hundreds of lumen-starved LEDs in over-sized fixtures,” he adds.

The CBM-380-RGBW produces up to 2500 lumens from a light-emitting surface area of 38mm2. With individual monolithic red, green, blue, and white die, it suits applications where a broad color gamut and superior color rendering are important, the firm says. The 6mm x 8mm optical source window allows the use of simple optics to eliminate the color shadowing and color mixing challenges that lighting designers typically face. The mechanical form factor is designed to support an array of tiled, replaceable modules, enabling fixture designers to scale the light output of their systems beyond 10,000-15,000 lumens.

The CBM-290-RGB has a total emitting surface area of 29mm2, producing up to 1500 lumens of total output from a 6mm x 8mm optical source. With individual large red, green, and blue die, it suits applications that require dynamic color changing and homogeneous color mixing, but with slightly reduced lumen output and color rendering index (CRI). It also eliminates the color shadowing typically seen with multi-color, multi-LED arrays. The CBM-290-RGB has the same form factor as the CBM-380-RGBW, allowing for an array of tiled, replaceable modules and scalable system output.

Both the CBM-380 and CBM-290 come in a connectorized, thermally efficient package with standard mounting features that simplifies system design by eliminating the added cost of PCB design and assembly of LED arrays. Luminus Devices claims that both modules are simple to service and upgrade, even after the fixture has been installed. Compared to the alternative of using hundreds of smaller LEDs, their high single-source output increases system reliability and results in faster design and manufacturing cycles, it is reckoned. The additive color mixing characteristics of multi-color LED lighting systems also contributes to higher overall system efficiencies, translating into energy savings. PhlatLight LEDs are also mercury-free, highly reliable, and have a lifetime of 60,000 hours with lumen maintenance of greater than 70%.
