Edison said that due to poor LED market conditions, LED TV replacement demand fell short, LED factories have rushed into LED lighting, coupled with technological improvements, the impact of low-power LED lighting products surged, resulting in the price of ASP lighting products Since the beginning of 2011, ASP of high-power LED lighting products has fallen by more than 15%, and ASP of low- and medium-power LED lighting products has fallen by 25%.
In addition to the sharp decline in prices, Edison pointed out that due to the large increase in low- and medium-power products, the demand for high-power LED lighting products, coupled with the company's end of optical transmission components, made the first half of the year at the bottom.
Looking forward to the second half of the year, Edison said that Q3 shipments are expected to be 20% more than Q2 shipments. The second half of the year is expected to be better than the first half of the year, but as ASP continues to decline, and the company continues to end the optical transmission business, so Q3 camp Whether the revenue can surpass Q2 remains to be seen. In 2011, the company's full-year profit will be worse than 2010. 
Many customers asked us what information we need for impedence control PCB.Here,there are two types for PCB manufacturer,a is single impedance ,just one trace ,two holes .and b is differential impedance,it always go with 1 pair (two trace with same width and space). For single impedance,you just tell us the trace width one which layer and what value you require .For differential impedance,trace width/space,layers and value. Our experience engineers will calculate following your instruction with Polar software.We may change trace width/space or stackup ,but please do not worry, if any changes,we will send you to approve before proceeding. Generally,the tolerance is 10%,and more accurate is 8% .All impedance boards ,we will test here and report.
[High-tech LED News] LED Taiwan factory Edison (3591) recently announced that Q2 revenue increased by 2.42% to NT$676 million, and revenue for the first half of the year was 1.336 billion yuan, down 9.74% year-on-year. The legal person estimated that Edison’s EPS for the first half of the year was about 1.8 yuan.
