Shanghai Research Center of Engineering and Technology in Solid State Lighting: Core competitiveness of semiconductor lighting in China
In light of the fact that China is not only an emerging country but also an emerging LED market, Chu Junhao, Ph.D of Shanghai Research Center of Engineering and Technology in Solid State Lighting addressed the core competitiveness of semiconductor lighting in China from the performance and direction perspectives of the core competitiveness.
He pointed out the fact that the incandescent products of Chinese manufacturers are three to four times cheaper than imported products as an example to demonstrate his point: the scale production does not equal to the core competitiveness.
He indicated that the difference of integrated factors among domestic products and the overemphasis on the midstream and downstream market will lead to a resource competition between manufacturers. The different sectors of the industry chain have to be foundation of the core competitiveness.
He further indicated that because the solid-state lighting industry is underpinned by advanced technology, the Chinese solid-state lighting makers need to start from the MOCVD sector and in the meantime, develop other core technologies in order to establish the core competitiveness. Moreover, the adoption of high-end technology and the comprehensiveness of technology system are nothing short of crucial as well.

LEDinside (TrendForce Corp.): Solid-State lighting/LED market trend in 2012
Due to the fact that the development of LED industry has been the focus of relevant industries over the past few years, Roger Chu, research director of LEDinside, presented a comprehensive report on “Solid-State Lighting/LED Market Trend in 2012.”
Chu’s report mainly included the estimation of the development trend, the outlook on both ends of supply-and-demand chain and the competition and cooperation of the LED industry. He pointed out that due to the rise of Chinese and South-Korean LED market, the LED price has more or less shown a decline in NB, TV, mobile device applications over the past few years. According to his report, the demand of HB LED will continue increasing in the coming years.He pointed out that the focus of the TV market has shifted to 3D sector, which results in a decrease in the LED penetration rate. Scenery lighting accounts for the biggest market share in 2010. He stated that currently, many countries have enact policies to support the LED industry. He used the loan policy by the South Korean government as an example to demonstrate his point.
Chu indicated that the LED penetration rate in Japanese market, which reached 18-20 percent in 2010, has increased by 20-30 percent due to the Japan earthquake. He believed even though the increase rate will slow down in July and August, but the increase will continue.
Besides, he also analyzed the upstream and downstream of the LED industry, including MOCVD, sapphire substrate and other sectors, and predicted the subsidy policies enacted by different governments.
