LED Engin has announced a world record in both flux and power density for high power, multi-colour LED lighting with its latest LZP family of RGBW emitters. The 25-die, 80W emitters deliver 3,800lm, the world’s highest luminous flux density from a 6.2mm² light emitting area on 12mm² emitter footprint. This has been achieved through an improved LZP package design that results in the industry’s lowest thermal resistance per package footprint of 0.1°C/W.

As a result, the LZP now gives designers of entertainment and architectural lighting the freedom to create more powerful yet slimmer, very compact lamps in innovative styles that appeal to customers. The emitter is the first of three recent multi-colour products in LED Engin’s development schedule announced in April. The others are the LZ7 seven colour emitter and the ultra-high power LZ4 4-die RGBW, which can be driven up to 3A/die.

The LZP series is available in two versions, featuring either a domed or flat glass primary lens for different applications. The LZP-00MD00 with its glass dome lens is typically used with a total internal reflection secondary lens to deliver high flux output. It’s a popular choice for architectural lighting, including wall-wash fixtures and accent and effect lighting. The flat lens of the LZP-04MD00 is particularly suited to punchy stage and studio lighting where beams of less than 10º are often required. Its compact étendue facilitates the use of zoom optics, mixing rods, light pipes or other optics to produce narrow beams.

Using only three of the latest LZP emitters, illumination equivalent to that from a typical 10,000 lumen (approximately 700W) HID bulb used in profile lamp can be achieved. Light absorbing colour filters are not needed, so efficiency is greatly improved. With 25 mixed-colour dies arranged closely, the series simplifies board and circuit design. It also enables a more compact fixture footprint than that of competing single-die or 4-die LEDs. What’s more, fewer secondary optical components are required, helping reduce the bill of materials and simplifying attachment of the optics.

LED Engin offers a full suite of total internal reflection optics suitable for use with the LZP emitters, offering a wide range of output patterns from 13 to 47°, which help designers create high-performing and unique solutions to lighting challenges. Zoom optics and optics for beams narrower than 10º are available from a third-party supplier in December.

David Tahmassebi, CEO and President, LED Engin, said: “These emitters once again demonstrate LED Engin’s technical innovation and leadership. We’re dedicated to developing LED products that enable lighting designers to express their creativity and produce better products for their customers, particularly in the competitive and highly demanding entertainment lighting sector.”
