LED Engin Has a Range of 4-Die RGBW Emitters for Wash Lamps

LED Engin has a range of 4-die RGBW emitters for wash lamps and follow spots used in stage lighting applications

Two variants are available - LZ4 that can be driven to 1A and LZ4-Plus that can be driven to 1.5A per die, producing up to 550 and 725 lumens output respectively.

The multi-colour LED die, which are mounted onto a multi-layer thermally efficient substrate, are capped with a flat glass primary lens.

Colour is controlled by individually addressing each die. There is also in-source colour mixing, so there is no need to attach colour filters to lamps.

The technology underpinning the new emitters is LED Engin’s LuxiGen platform. LED die are fixed to a low thermal resistance substrate using a gold-tin eutectic die-attach process.

"This allows users to drive the LED dies with higher current and generate more light, while keeping junction temperatures low to ensure long operating life," said the supplier.

In the LZ4 RGBW emitters, four die of the same dimensions are closely packed together onto each substrate for optimized étendue. This produces narrower, punchy beams with better color mixing and sharp cut-offs.

The product also has its anodes and cathodes aligned, simplifying board design when using multiple emitters in a single lighting fixture.

“Stage and studio lighting have some of the most demanding requirements for LED emitters. Our technology gives lighting designers greater creative freedom," said president and CEO of LED Engin, David Tahmassebi.

LED Engin will be demonstrating the LZ4 flat lens RGBW emitters at Prolight + Sound, Frankfurt, Germany, April 10-13, 2013, Hall 9.0, F43.
