LZ4-Plus emitters paired with optics produce breakthrough lighting

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. 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.

Being able to individually address each die results in precise colour control, in conjunction with in-source color mixing and without the added complexity and cost of attaching color filters to lamps. The compact LZ4 emitters, which are based on LED Engin’s proprietary LuxiGenTM platform, 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. LZ4-Plus emitters are offered in single flux bins per color, reducing the need to mix multiple bins.

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.

The products are being unveiled for the first time at LDI –the annual entertainment lighting show held in Las Vegas.
