Seven-Color High Power LED Emitter Enables Rich Stage Lighting

LED Engin has announced the world's first 7-color, high power LED to be produced on a single emitter. The compact LZ7-04MU00 emitter enables the design of stage or architectural lighting that produces sophisticated effects over the full color spectrum. Its RGBW die are complemented by phosphor-converted (PC) amber, cyan and violet to provide richer, wide-ranging color effects.

PC amber delivers the same saturation as regular amber but with 5 times the flux at temperature, cyan fills the spectrum gap between blue and green, and violet enables black or crisp white lighting effects. Typical stage and studio applications include moving heads with zoom optics and round wash lights. In architectural lighting, the emitters enhance the performance of everything from static lights to linear wash lights.

The flat lens LZ7 emitter, which has a 7mm x 7mm footprint, comprises 7 individually addressable die assembled onto a 3.8mm light emitting surface and capped with a low profile glass lens. This ultra-thin construction means that mixing rods can be positioned as near as possible to the die to maximize coupling efficiency

LED Engin's proprietary multi-layer, multi-channel substrate technology underpins the performance of the LZ7. The substrate's thermal resistance is only 1.4°C/W and it dissipates up to 20W effectively. RGBW individual dies can therefore be driven, one at a time, to a maximum current of 1.5A. Alternatively, a single amber, cyan or violet die can be driven at up to 1A. In a third operating mode, all dies can be driven simultaneously at 850mA.
