LED Engin combines its compact LZ4-Plus emitter with Gaggione's optics to deliver breakthrough stage lighting performance
San Jose, CA, USA: November 22, 2013: LED Engin, Inc., a leader in high flux density LED products, announces a combination of LZ4-Plus emitters and Gaggione 8 to 45-degree zoom optics that produces class-leading candela/lumen performance, beam quality and control. LED Engin's LZ4-Plus are compact, 4-die RGBW emitters for wash lamps and follow spots. They can be driven to 1.5A per die to produce 30% higher output than rival products. Matched to the Gaggione lenses, this technology enables luminaire manufactures to design much smaller, lighter and more powerful products than have been possible until now. The resulting entertainment luminaires will help lighting designers create stunning effects by delivering amazingly bright, smooth, flat, progressive beams that feature soft yet clearly defined edges over the full color spectrum... read all
When driving each die to 1.5A reliability and operating life are not compromised because LED Engin's proprietary, multi-layer, thermally efficient substrate dissipates heat very effectively.
Precise color control is achieved via the ability to individually address each die, in conjunction with in-source color mixing and without the added complexity and cost of attaching color filters to lamps. Based on LED Engin's proprietary LuxiGenTM platform, the compact LZ4 emitters, capped with flat glass primary lenses, are used with secondary optics, including zoom lenses and imaging optics. The die are mounted close together to create a very small light source. This has two benefits: it maximizes in-source mixing to produce uniform color across the beam and it enables very narrow beam angles to be created. Precisely controlled narrow beam angles, down to 8 degrees or less, can only be produced when a very compact light source is employed.
The total internal reflection (TIR) zoom lens developed by Gaggione is one of the most efficient in the market, maximizing candelas per lumen (cd/lm) in the beam. Gaggione also offers fixed, high precision TIR lenses with narrow, medium, wide or elliptical beam angle profiles.
LZ4-Plus emitters are offered in single flux bins per color, reducing the need to mix multiple bins.
The products are being unveiled for the first time on Booth 2341 at LDI -the annual entertainment lighting show held in Las Vegas, opening today.

San Jose, CA: April 2, 2013: LED Engin, Inc., a leader in high lumen density LED products, announces the LZ4 flat lens family of compact, 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, some 30% more than rival products. The multi-color LED die, which are mounted onto LED Engin's propriety, multi-layer thermally efficient substrate, are capped with a flat glass primary lens... read all
Precise color control is achieved via the ability to individually address each die, in conjunction with in-source color mixing and without the added complexity and cost of attaching color 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 facilitates 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 color 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 for optimized étendue. This produces narrower, punchy beams with better color mixing and sharp cut-offs. 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.
President and CEO of LED Engin, David Tahmassebi, comments, "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 color changes to create dramatic effects."
The new emitters are available now direct from LED Engin.
LED Engin will be demonstrating the LZ4 flat lens RGBW emitters at Prolight + Sound, Frankfurt, Germany, April 10-13, 2013, Hall 9.0, F43.
