LEDs ♦ news digest
while simultaneously lowering our impact on the environment. Additionally, we now have a much better understanding of our energy usage which will help in downstream decisions. We are very thankful for the vision of the North Carolina Board of Science and Technology and those state legislators who support the NC Green Business Fund.”
The market for nitride semiconductor devices was $12 billion in 2010 and is expected to reach $90 billion over the long term; $60 billion in visible lighting applications and $30 billion in power device applications.
Quantum Wafer uses Aixtron
to ramp up production The three reactors will be used to produce gallium nitride chips for use in HB-LEDs
Aixtron SE has a new MOCVD systems order from existing customer Quantum Wafer Inc., China.
The new contract is for three more Aixtron MOCVD units. All systems will be dedicated to the growth of high brightness LED (HB-LED) wafers based on GaN materials.
The order was placed in the fourth quarter of 2011 and delivery will take place during the first quarter of 2012. Aixtron’s local support team will install and commission the new reactors in a state-of-the-art clean-room facility at Quantum Wafer’s factory in China.
“We have been very impressed with the performance of the two 42 x 2” Aixtron G4 MOCVD systems that we purchased in 2011,” Shu Yuan, General Manager of Quantum Wafer, comments. “We therefore wish to add more equipment from Aixtron, as we implement the next step in our strategic plans.”
Quantum Wafer is a semiconductor optoelectronic materials and device company located at the heart of the Zhujiang Delta Industry Area of China. A manufacturer and provider of semiconductor wafers, the company supplies materials for the manufacturing of LED devices, as used in a wide range of applications such as LED TVs, mobile phones, solid-state lighting, large-screen displays and traffic lights.
Seren’s substantial funding to brighten up the LED market
The £1.8 million will be used to purchase key capital equipment for HB-LED pilot scale development and create a specialist engineering team
Fusion IP’s LED technology division, Seren Photonics, has raised £1.8 million in equity funding .
Seren says this will enable the firm to transfer its cutting edge technology to manufacturing partners around the globe.
The first of these exploitation agreements was recently announced with an Indian manufacturer.
Seren’s revolutionary new processing technique, developed by Tao Wang, a professor at the University of Sheffield, is claimed to greatly increase the efficiency at which a HB-LED converts an applied voltage into light. This significantly reduces heat generation under normal operating conditions.
Successful demonstrations of the patent pending technology have resulted in a significant increase of the light output compared to untreated devices. This means that either much brighter LED lamps can be manufactured or that the power consumption of LED lamps can be reduced.
Seren’s technology is targeted at the large and fast growing white light HB-LED markets, such as back lighting for laptops and TVs, signs and displays, as well as domestic, architectural and street lighting.
Godfrey Ainsworth, Seren’s Chairman comments, “This market is currently worth an estimated $7 billion in 2011 and is set to grow to $20 billion by 2014.HB-LEDs are set to replace incandescent lamps as governments around the world bring in legislation banning the manufacture and sale of incandescents and concerns increase about the poor light quality and environmental contamination fears from compact fluorescents. The rate of adoption will accelerate as the brightness of HB- LEDs increases and the cost of manufacture reduces.”
Seren’s funding round raised a total of £1.8 million from a number of investors, including I2BF Global Ventures (£1,100,000), Fusion IP plc (£300,000) and IP Group plc (£400,000).
The funding will be used to purchase key capital equipment for HB-LED pilot scale development and create a specialist engineering team for the transfer of Seren’s processes to its commercial manufacturing partners.
Post funding Fusion will have a 40.2% undiluted shareholding in Seren.
Carl Griffiths, CEO of Seren Photonics says, “We are delighted to have secured this significant investment from our existing shareholders and from I2BF. The funds will enable us to accelerate the transfer of Seren’s technology to manufacturing partners. This will start with our existing collaboration partner in India and we are already in discussion with HB LED manufacturers in China about the possibility of licensing or creating a joint venture manufacturing facility. We will continue to look for other potential partners outside of these territories .”
David Waserstein, Partner and Director of Investments at I2BF, adds, “We believe LEDs will play a large role in reducing energy intensity for a range of municipal and industrial users, and that Seren is well-positioned to help drive that growth due to the double impact of its technology on both brightness and reduction of heat loss. We are also pleased to be supporting a UK university spin out at this time, which has been ably supported by our co-investors Fusion IP PLC.”
