LED emitter boosts output by 250 %

August 29, 2012 // By Christoph Hammerschmidt
California-based LED Engin Inc., raises the bar for lumen density. The company has announced a family of devices that deliver 2.5 times the lumens of existing LZ4 products within the same 7mm x 7mm footprint. The new LZ9 emitter more than doubles the Lux on Target, making it ideal for directional lighting fixtures such as the spot, accent and downlighting used in retail and commercial applications

LED Engin also offers a family of secondary total internal reflection (TIR) lenses in Spot, Narrow Flood and Flood beams. The LuxiGen single emitter/ single lens combination, available in color temperatures ranging from 2700K Warm White to 6500K Cool White, provides the equivalent performance of a 75W PAR20 or PAR30 halogen source (reference: ENERGY STAR Integral Lamp Center Beam Intensity Benchmark Tool). The LZ9-series is the first LuxiGen series to be introduced with both standard CRI of 85 and a CRI 90 option for applications that demand the highest levels of color rendering.

With 1300 lumens at 3000K and 1450 lumens at 5500K color temperatures, the LZ9 emitter incorporates 9 die in a compact, 3 x 3 series-parallel configuration, package and, like the rest of the LuxiGen platform, uses a patented multi-layer ceramic substrate engineered to minimize stress on the die. The substrate has low thermal resistance to lower the junction temperature of the die for consistent performance over the service life of the product.

The LZ9 emitter and TIR lens combination leads the industry in terms of 'lux efficacy' or lux/Watt performance, a term that is more accurate than lumens/Watt to describe the usable light delivered in downlighting applications.

The LuxiGen LZ9 emitter fills a gap in LED Engine's product offering in the popular 1000 lumen range for complete systems which are commonly used to replace 50W and 75W halogen sources, the company said.

The device is available in a range of color temperatures between 2700K and 6500K. Maximum performance of 1450 is reached at 5500K. Three parallel strings of three die each are available as in series configuration. The devices can be obtained either as "naked" emitters or mounted on metal core PCB for easy assembly.
