led high bay lighting is at the period of golden three years with fast growing penetration rate. The constant reduction of cost has led to growing household LED market, and other areas of lighting application are also spreading. China has the cost advantage in the niche field of LED lighting, and will become the major base for LED Lights production. 1. Industrial growth rate: downstream > middle stream > upstreamAccording to survey data, the industrial output value in 2013 was 263.8 billion yuan, with year-on-year growth of 28%. The growth rate in 2012 was 34%. In the upstream, middle stream and downstream of LED industrial chain, application chain grows faster than encapsulation chain and encapsulation chain grows faster than chip chain.2. The growth rate of epitaxial chips had reached 17% in 2013
