Testar Expands LED Chip Testing Services
2010-03-10
Demand for Energy Efficient Light Emitting Diode (LED) Technology Fuels New Testing Services Sector
Testar Electronics Corporation, specialists in testing and optimizing Light Emitting Diode (LED) chips and a subsidiary of Chroma ATE Inc., today announced it has signed definitive agreements to become an independent entity and to receive an institutional investment from WI Harper Group. This infusion of capital allows the 3-year old subsidiary to expand its operations and further establish its leadership role in providing testing services for LED chip manufacturers across Asia.
“We recognized early on that LED chip manufacturers have limited testing capability and must comply with evolving standards. By outsourcing LED testing, customers benefit from increased efficiency and improved quality, ensuring that manufacturers can achieve competitive prices for their high-grade chips.”
The ever-increasing demand for energy efficient and cost effective lighting is driving the rapid growth of LEDs to support a range of applications such as LCD-TV backlighting, laptop PC and computer screen backlighting and general illumination. Industry analyst iSuppli projects shipments of LEDs to nearly triple over the next three years from 63 billion in 2010 to 166 billion in 2013.
This proliferation of LED-related products is creating a new professional services sector: LED chip testing. “LEDs are now used in street lighting, consumer electronics such as backlit TVs, vehicles and numerous unique
applications,” said Mr. Leo Huang, founder, CEO and chairman of Chroma and founder of Testar Electronics Corporation. “We recognized early on that LED chip manufacturers have limited testing capability and must comply with evolving standards. By outsourcing LED testing, customers benefit from increased efficiency and improved quality, ensuring that manufacturers can achieve competitive prices for their high-grade chips.”
“Testar is ideally positioned to take advantage of the vast business opportunity in LED testing services,” said Peter Liu, Chairman of WI Harper Group. “The insatiable demand for LEDs is placing pressure on chip manufacturers to increase throughput and Testar plays a critical role in this strategic market.” Testar continues WI Harper’s LED investment program that includes LED chip maker SemiLEDs Corp. and LED emitter, light engine and fixture provider NeoPac Lighting Group.
New Single/Dual White LED Flash Driver
2010-03-10
austriamicrosystems’ New Single/Dual White LED Flash Driver Improves Picture Quality in Mobile Phones and Digital Still Cameras austriamicrosystems, a leading global designer and manufacturer of high performance analog ICs today announced the AS3645 LED flash driver. This inductive, ultra small, high- efficiency single/dual LED flash driver offers 25 per cent higher output current than existing equivalents. The higher flash power enhances picture and video quality especially in low light environments at same system size.
The AS3645 inductive flash driver drives up to 1000 mA and can be used in single LED flash or double LED flash environments. The high- side current source works with up to 2x500 mA with two LEDs in serial configuration and up to 720 mA with one LED. When driving two LEDs in series, LEDs draw identical
