LED Engin multi-emitter LED targets challenging halogen-replacement applications

Aug. 31, 2012
The LZ9 LuxiGen LED delivers up to 1600 lm and LED Engin is targeting the SSL device at directional retrofit lamps for retail and commercial applications.

LED Engin packs nine die in its new LZ9 LuxiGen packaged LED, and the device delivers 1600 lm in a 6500K cool white version and 1350 lm in a 3000K warm white version. The company says that the solid-state lighting (SSL) emitter is a good match for replacing halogen sources in directional lamps such as PAR20 and PAR30 applications.

Target applications such as retail demand both good beam control and excellent color rendering and LED Engin says that the new product delivers on both. Previously the company has offered LuxiGen devices with a CRI of 80, but the new LED family comes with the option of a 90 CRI.

The LZ9 family offers 2.5 times the lumen output of the prior generation LZ4 family, and LED Engin says that it also more than doubles the lux on target. LED Engin supplies secondary total internal reflection (TIR) optics that can produce spot, flood, and narrow flood beams.

Halogen target

"With the addition of the LZ9, LED Engin continues its focus on maximizing lux on target and lux efficacy at all power levels, giving our customers the freedom and flexibility to design for a range of applications," said Uwe Thomas, vice president of product management. "The LuxiGen LZ9 emitter fills a gap in our product offering in the often-demanded 1000-lm range for complete systems which are commonly used to replace 50W and 75W halogen sources."

Based on the Energy Star Integral Lamp Center Beam Intensity Benchmark Tool, LED Engin says that the LED enables SSL lamps that perform comparably to 75W PAR20 and PAR30 halogen lamps. The company will supply the LED as a component or mounted in a chip-on-board (COB) package that uses a metal core circuit board.

The LEDs are available at CCTs down to 2700K. The array is electrically configured as three parallel strings of three emitters connected in series. The multi-emitter approach allows LED Engin to control CCT to within a 3 MacAdam Ellipse range for lamp-to-lamp color consistency.
