New RGBW LED emitters with 30% more output target stage lighting

LED Engin has unveiled a new flat lens family of compact, 4-die RGBW emitters for wash lamps and follow spots used in stage lighting applications. Two variants are available: the 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, some 30% more than rival products. The multi-colour LED die, which are mounted onto LED Engin’s propriety, multi-later thermally efficient substrate, are capped with a flat glass primary lens.

Precise colour control is achieved via the ability to individually address each die, in conjunction with in-source colour mixing and without the added complexity and cost of attaching colour filters to lamps. The compact LZ4 emitters with flat glass windows can be used with various secondary optics, including zoom lenses and imaging optics, and are capable of delivering beam widths down to 6 degrees in such systems.

This latest emitter technology enables the design of more reliable, controllable and versatile studio lighting compared with high intensity discharge (HID) lamps, often in much smaller enclosures. The LEDs also deliver more consistent colour over their service life, run much cooler and save energy.

The technology underpinning the new emitters is LED Engin’s LuxiGen platform. LED die are fixed to a low thermal resistance substrate using a unique 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. In the LZ4 RGBW emitters, four die of the same dimensions are closely packed together onto each substrate.

Utilizing a flat glass lens allows the primary optic to be closer to the die for highest coupling efficiencies and facilitating the use of zoom optics, mixing rods, light pipes and other TIR optics. The product also has its anodes and cathodes aligned, simplifying board design when using multiple emitters in a single lighting fixture.

Commenting President and CEO of LED Engin, David Tahmassebi, said, “Stage and studio lighting have some of the most demanding requirements for LED emitters. Our technology not only produces the highest ‘Lux-on-Target’ for a given power rating, but also gives lighting designers greater creative freedom. Fixtures that use the technology produce focused, punchy light with minimal glare and are capable of fast, precise colour changes to create dramatic effects.”

The new emitters are available now direct from LED Engin.
