and Taiwanese enterprises enjoyed the most rapid progress.
In 2010, LG Innotek presented the highest growth margin, and the revenue from the LED Division advanced to US$783 million from US$229 million in 2009. Nevertheless, LG Innotek sacrificed the profit whose growth margin was far from that of revenue. The revenue of Samsung LED also progressed considerably to US$1.14 billion from US$508 million in 2009, ranking the global No.2; while that of South Korea›s Seoul Semiconductor climbed 105% to US$726 million.
Nichia, the global No.1 for consecutive 8 years since 2003, also advanced rapidly, and its LED revenue rose 65% against 2009 to US$2.246 billion. China is in possession of more than 150 LED enterprises, but their total revenue is inferior to that of Nichia and the total operating profit fails to meet 40% of Nichia›s profit.
China›s LED industry remained a hotspot in 2010 and a great number of enterprises successively announced the investment of at least RMB10 billion (US$1.57 billion). Chinese government was eager about LED upstream and offered the subsidy of RMB10 million for each MOCVD machine, which stimulated the LED investment upsurge.
Chinese Mainland enterprises purchased only 25 MOCVD machines in 2009, but the number expanded to 267 in 2010, and it surpassed 450 considering the MOCVD machines purchased by Taiwanese enterprises in Mainland China. In 2010, the global shipment of MOCVD machines totalled just 768.
The MOCVD machines worldwide are almost monopolised by Aixtron and Veeco who have benefited a lot from the investment zeal of Chinese enterprises. In 2010, Veeco launched the K465I in the Chinese market, posing great pressure on Aixtron, and its revenue soared 230%.
Different from automobiles, MOCVD machines require debugging first, which will take2-4 months for veteran manufacturers but possibly even longer time for those without experience of the technology.
Chinese Mainland manufacturers have frequently headhunted Taiwanese LED talents with the promised salary by several folds; however, few
have been attracted in view of the probable lay-off after the completion of debugging. Consequently, the actual mass production ratio of the available 267 MOCVD machines in 2010 is not high in 2011.
Since early 2011, partial local governments of China have suspended the procurement subsidy over MOCVD equipment taking into account possible overcapacity and insufficient utilisation of MOCVD devices.
Cree LEDs provide University of Michigan’s “Big House” with a makeover
High-definition LED video screens have been Installed at Michigan football stadium.
Football fans of the University of Michigan kicked off the 2011 season enjoying a new look to Michigan Stadium, now complete with newly upgraded scoreboards from Lighthouse Technologies.
The state-of-the-art video displays and scoring systems feature Screen Master high-brightness LEDs by Cree, delivering crystal-clear, high definition images to fans throughout “The Big House.”
A college football icon, Michigan Stadium was built in 1927 and is the largest stadium in the United States, consistently boasting game day crowds of more than 100,000 fans. On September 10, the stadium hosted a record crowd of more than 114,800 Wolverine and University of Notre Dame fans at the first night time football game ever played at the “Big House.”
The scoreboard replacement project began in March 2011, with the addition of two Lighthouse outdoor LED video systems. Positioned in each of the end zones, the high-resolution LED video boards are 40 percent larger than the previous system, providing in-game broadcast capability, instant replay, animation and dynamic promotional content in vivid colour and ultra-sharp detail.
More than three million Cree Screen Master CLV6A LEDs illuminate each of the LED video boards. With industry-leading water-resistant packaging, Cree’s
