Lattice Power Announced The Volume Production of Its Generation GaN-Based High Powered LED

Tags: Market View, led

The pioneer of blue/white gallium nitride-based LEDs on silicon substrate says it is creating the opportunity for a sharp reduction of LED lighting prices Lattice Power Corporation has announced the start of volume production of its new generation GaN-based high powered LEDs on silicon substrates. The company says this development sets the backdrop for a sharp reduction in the prices of energy-efficient LED light bulbs worldwide. Lattice Power claims to be the first and only company in volume production of GaN-on-Silicon LED chips, with products that are comparable to high-end chips that rely on conventional sapphire substrates. Operating at a current of 350mA, the 45 mm product is capable of producing 130 lumen cool white with an efficiency of 120 lumens for each watt consumed. What's more, silicon substrates are readily available in larger diameters and come at a fraction of the cost of sapphire substrates resulting in substantial cost reductions for downstream manufacturers. Twenty strategic customers have received the LEDs and will incorporate them into indoor and outdoor lighting applications. Lattice Power's silicon substrate-based LED series encompasses four different chip sizes: 28mm x 28mm, 35mm x 35mm, 45mm x 45mm, and 55mm x 55mm. Chip power ranges from 0.5W to 2W. Lattice Power has always invested heavily in research and development in silicon substrate-based LED technology. The commercialisation of its silicon substrate-based-power chip series represents a second milestone for Lattice Power after the launch and volume production of its smaller size silicon substrate-based LED chips used in display and signage recently. Using GaN-on-Silicon technology to make commercial grade LEDs in the United States and Europe has shown promising laboratory results, but not at volume production. While moving towards mass production, Lattice Power says it has filed more than 200 innovative international and domestic patents in this field. "Lattice Power not only has the state-of-the-art silicon substrate-based LED technology, but also a world class technical and management team," says Sonny Wu, the managing director of GSR Ventures and chairman of Lattice Power. "With the big growth of solid state lighting and Lattice Power's introduction of high power LED product family into the lighting market, the company has once again proven its cutting-edge development and manufacturing capabilities. I'm highly confident that Lattice Power will grow into a world class solid state lighting company." "Since its birth, Lattice Power has focused on high efficiency, low cost and high reliability LEDs on silicon. To get to where it is now, Lattice Power has faced lots of hurdles and challenges and overcome many obstacles and heart-breaks," adds Wang Min, the co-founder and CEO of Lattice Power. "But we have persevered and gained enormous traction with customers. Our silicon-based LED technology will finally open the door for LED bulbs to be used in millions of households." Leading industry experts now predict that future LED chip cost savings could be as much as 70% greater than with the current mainstream products when manufactured on larger diameter silicon substrates. Lattice Power is actively working on 150mm GaN-on-silicon technology and is expecting to transfer its production to even larger diameter silicon substrates in 2013. Source: compoundsemiconductor.net
