Plessey launches single-chip high-power 7070 LEDs

UK-based lighting and sensing product and component maker Plessey has launched its 7070 high-power LED range (PLW7070GA.).

The PLW7070 products take advantage of Plessey's MaGIC (Manufactured on GaN-on-Si I/C) technology and provide a high-power LED component in an industry standard package footprint, complementing Plessey's existing family of i2LED high-power products. Using its proprietary gallium nitride on silicon (GaN-on-Si) high-voltage technology, Plessey says that it has been able to use a single LED die to improve thermal performance, improve far-field imaging and dramatically reduce cost over incumbent solutions.

Plessey provides components and solutions spanning the whole lighting value chain. Lighting system designers and specifiers can access its design, build and supply chain expertise from GaN-on-Si blue die all the way up to complete luminaires and fixtures. The PLW7070GA high-power LED with multiple junctions integrated in a single chip eliminates shadow effects and provides optimized far-field imaging, says the firm. Compatible with industry-standard secondary optics and operating at input currents from 350mA to 3A (1-15W power), Plessey's low-cost, high-power single chip LEDs are available in a full range of correlated color temperature (CCT) and color rendering index (CRI) options for demanding outdoor and commercial lighting applications.

"The PLW7070 range has been designed using our unique integrated multi-junction die architecture that provides us with a differentiated solution for a diverse range of high-power applications in high-bay, floodlighting, street lighting, spot lighting and down lighting, in addition to portable torches and lamps," says director of sales Giuliano Cassataro. "The move for designers to mid-power products because of low cost can now be reversed, as we can provide solutions where the overall fixture costs are up to 50% lower. GaN on silicon is really starting to come into his own," he adds.

"The key features and benefits we bring to customers and the LED lighting market with the Plessey 7070 range is a custom aluminium nitride ceramic lensed package with an industry-standard solder pattern and footprint," says chief technology officer Dr Keith Strickland. "Its low thermal resistance of less than 2°C/W, combined with a high maximum junction temperature of 135°C for good thermal management in demanding thermal environments, is critical in heat management," he adds. "Using a single GaN/Si multi-junction chip for 12V and 24V operation, Plessey is setting a new benchmark for far-field imaging and the use of secondary optics in narrow-beam-angle applications," he claims. "Superb maintenance of luminous flux is possible over a wide temperature range, and the in-built ESD protection provides stable yield through system manufacture and operation."
