LEDs ♦ news digest
Nantong Tongfang Semiconductor has received one of its TurboDisc K465i MOCVD systems for research of GaN-on-silicon high brightness LEDs. The system was delivered to Tongfang’s new LED Technology Centre in Nantong, China and is capable of growing up to 8 inch
wafers.These are just a handful of companies who are investing in the GaN-on-Silicon market.
Azzurro’s white paper’s aim is to support the LED industry’s move to GaN-on-Silicon.

Seoul Semi AC LED module reaches new heights
The firm’s latest Acrich2 module saves energy by up to 50 percent and improves compatibility with Triac dimmers
Seoul Semiconductor has announced that its latest Acrich2, AC LED module, which performs at 100 lm/ watt is now available for volume production.
Acrich2 provides lighting designers with a high efficacy light source which also has a high power factor, and improved Total Harmonic Distortion (THD) performance.
new dimming functions such as touch sensor and WIFI control dimming.
The Power Factor improvement which is up to 0.99, will also save costs in electricity. Conventional LED lighting products have lower Power Factors starting at 0.5 but mostly in the 0.7 to 0.8 range.
Seoul Semi says this Acrich2 AC LED module will help the performance of the power grid.
Seoul Semi’s Acrich operates effectively due to its ‘Integrated Multi-cell’ technology, which has been developed by the firm for over 10 years. As a result of this research, Acrich operates on both alternating current and direct current. What’s more, it tolerates a wide range of voltages.
4W to 16W Acrich2 AC module are available now and the firm’s production line is ready to manufacture large quantity
orders.Customised Acrich2 solutions are also available.
According to the LED market reports issued by Strategies Unlimited in the U.S., Seoul Semiconductor is the world’s fifth largest LED supplier, holding more than 10,000 patents.
PhotonStar LED nets a new finance director
The former CFO of SPI Lasers, a manufacturer of fibre lasers, David Holloway assisted in developing the business, including raising additional capital to support growth and also, ultimately, facilitating the sale of the company to the German engineering multinational Trumpf Gmbh

In traditional solid state lighting solutions, additional components and costs are required to provide an offline driver solution with acceptable dimming performance. Seoul Semi says its Acrich2 solution can save about $2 over these traditional solutions.
The new AC module also provides a DC dimming interface that allows the designer to easily integrate
PhotonStar LED Group, a British designer and manufacturer of smart LED lighting solutions, has appointed David Holloway as Group Finance Director. The appointment came into effect on 3rd September 2012.
Holloway is a chartered accountant with over 30 years commercial experience of senior finance roles, covering public companies and technology & engineering businesses, including SPI Lasers plc, IMI plc and Williams Holdings plc.
