RGB chipsets improve projector performance by up to 40%

Luminus says its latest nitride Big Chip LED is the world's brightest

Luminus Devices has announced it has tripled the brightness of its semiconductor green LEDs over the last five years, and expects to at least double it again.

Green light is the major primary colour that contributes to white light generation in systems with Red-Green-Blue illumination, and the performance of Green LEDs is considered by the industry as the major limiting factor in replacing high pressure mercury lamps in projection displays.

Combined with its thermally-enhanced packaging technology, Luminus' latest achievements in Pure Green LED output allow its projection-optimised RGB chipsets to achieve new performance levels in projection system categories covering portable, home video, video walls and mainstream business and education.

For instance, the company's latest 5.4 mm2 green LED can output up to 3000 lumens at a current density of 3.0 A/mm2. This chipset allows system manufacturers to design portable LED projectors with performance in excess of 700 lumens, a 40% improvement over products introduced only 1 year ago.

"The rapid pace of improvement of our Pure Green LEDs is a testimony to the large untapped potential of this technology," says Arvind Baliga, VP of Engineering. "Alternative approaches such as phosphor conversion technologies rely on mature platforms with limited upside potential and also come with a broad spectrum that results in increased optical losses of up to 20%."

"Our customers recognise that Luminus Projection Chipsets enable the brightest projectors today and more importantly, place them on a faster trajectory to transition their portfolio to a lamp-free model. Increased investment in R&D and rapid prototyping will dramatically accelerate our progress in reaching brightness targets needed to move into the business and education segments," notes Baliga.

"Luminus' world's brightest green LED just got better, and the best testimony to this achievement is over 1 million consumer and professional of lamp-free projection displays that have been deployed using our technology - a market that did not even exist only 4 years ago," adds Stephane Bellosguardo, Director of Global Product Marketing at Luminus Devices.

"After virtually eliminating lamps in markets such as video walls, our technology is now gaining similar momentum in consumer video, education and business projection markets. With RoHS exemptions for most high pressure mercury lamps set to expire in 2015, these latest advancements in Pure Green LED technology provide our customers with a path towards an environmentally friendly light source that combines cost-effectiveness and performance."

Luminus will be showcasing its latest advances in LED technology at InfoComm 2012 in Las Vegas at booth #C7942 at the Las Vegas Convention Centre.
Connecting the Compound Semiconductor Industry

The 13th CS International conference builds on the strengths of its predecessors, with around 40 leaders from industry and academia delivering presentations that fall within five key themes: Ultrafast Communication; Making Headway with the MicroLED; Taking the Power from Silicon, New Vectors for the VCSEL, and Ultra-wide Bandgap Devices.

Delegates attending these sessions will gain insight into device technology, find out about the current status and the roadmap for the compound semiconductor industry, and discover the latest advances in tools and processes that will drive up fab yields and throughputs.
