Multi-colour emitters deliver punchier stage lighting over a greater distance

LED Engin has announced a trio of multi-color emitters that deliver punchier stage lighting over a greater distance and enable compact lighting fixtures to be designed with fewer emitters. With unrivalled high luminous flux density and beam intensity, the products’ benefit from LED Engin’s proprietary multi-layer thermally efficient substrate, robust die-attach and advanced optical technologies. Geared towards high performance wall wash lamps, moving heads with zoom optics, and follow spot fixtures: the LZ4 is a multi-colour (RGBW) 4-die flat top emitter using a new 40% thinner package with half the thermal resistance of the previous generation; the LZ7 7-die (RGBW, cyan, amber and violet flat top emitter; and the LZP 25-die RGBW emitter in flat top or dome lens options, both utilizing the same new package technology. Precise colour control is achieved via the ability to individually address each colour, in conjunction with in-source color mixing. With its significantly lower thermal resistance, just 0.6 degrees per watt, the LZ4 can be driven harder – up to 3A per die – to provide the highest flux density in its class. Its close packed 1mm2 dies provide compatibility with existing zoom lens systems or those developed specifically for the LZ4 from Gaggione and Fraen Corporation. With lower thermal resistance which allows the dies to run cooler, secondary optics can be positioned closer to the light emitting surface without degradation. Providing the same flux density per die as 4-die products, the LZ7 emitter adds amber, cyan and violet to existing RGBW channels to achieve a richer and wider colour combination for more sophisticated mixing. This solution, specified at 850mA per die, can be boosted up to 1.5A if required. Secondary zoom optics (a mixing rod and collimator) have been created especially for the LZ7 by Fraen Corporation to enable existing moving head designs to be instantly and easily upgraded to 7 colors. Being the same size as a standard LZ4 emitter, virtually all fixtures can be upgraded to seven colours by simply switching to the LED Engin LZ7 emitter. The 25-die LZP emitters with four independently colour-controlled channels (RGBW) can be packed closely in a 3-or-4 up high power array to allow slimmer profile lamps or new moving head designs. The glass dome and flat top primary optic versions are compatible with TIR and mixing rod secondary optics. In addition to stage lighting, the deployment of LED Engin’s 84mm 13, 21, 36, and 47 degree secondary TIR optics will enable ‘plug and play’ design capability for architectural fixtures too. President and CEO of LED Engin, David Tahmassebi, said: “LED innovation now meets the challenging requirements that professionals demand of stage lighting. The new emitters from LED Engin deliver punch that is ideal for spot, moving head or wash light fixtures. And when it comes to emitting the maximum multi-colour light from a tiny surface area, fixture manufacturers need look no further – particularly given the ground-breaking level of thermal resistance they offer.”
