Welcome to LIGHTimes!

The opportunities presented by the increasing rapid adoption of high brightness LEDs, in all their forms and applications, represents nothing short of a "digital revolution" for a previously "analog" world. LEDs are having a substantial disruptive effect on a number of established technologies, and where there is disruption, there is an intense need for information.

LIGHTimes Online is here to serve the information needs of the LED industry supply chain, as well as integrators and non-architectural application solution providers with technology, product and market news updates for these rapidly evolving devices. Our readership also includes LED packagers, technology enablers and service companies seeking the answers to how best to meet their customers' needs.

For architectural lighting and applications news of interest specifically to lighting designers, specifiers, and architectural lighting decision makers, along with luminaire designers, lighting system integrators and lighting subsystem developers, please visit our sister publication, Solid State Lighting Design.

Supposed to be a picture here... Plessey Achieves 120 lm/W with GaN-on-Si LEDs in Lab and its GaN-on-Si LEDs to Power 8point3's Linear Lighting Products
... Plessey Semiconductor of Plymouth, UK reports that the company has agreed to supply its gallium nitride on silicon MaGIC (Manufactured on GaN-on-Si I/C) high-brightness LEDs to UK-based LED luminaire producer 8point3 Ltd. 8point3 plans to use the Plessey LEDs in its new Sabre Architectural range of LED linear lighting products, which will be officially labeled ‘Made in Britain'. Plessey asserts that that recent performance improvements in its MaGIC LEDs have made them competitive with any LED technology. In related news, Plessey announced that its GaN-on-Si MaGIC high-brightness LED technology has achieved light output of 120 lumens per watt...

LEDs Taking Over the World... Guest Commentary: Sapphire Substrate Advances Lead To Brighter LEDs at Lower Costs
... The adoption of solid-state lighting is fueling market growth for high-brightness LEDs. It's a competitive market, and each manufacturer is looking for the keys to greater light output at a lower cost. In recent years, the most significant advance in cost per lumen has been the adoption of patterned sapphire substrates. By etching a pattern onto the polished sapphire substrate, total light extraction efficiency (LEE) can be increased by as much as 30 percent.Sapphire is the material used as...  Read the rest...(or permalink here)
