Through the four stages of LED manufacturing value chain, the application of chemical materials includes chip manufacturing, packaging, module manufacturing and lamp assembly. Therefore, when predicting the growth trend of LED industry, manufacturers or research institutions can first see some early trends through the growth model of LED chemical material revenue. The 2016 research report on China's LED substrate materials mentioned that chemical products at every stage of the LED lamp production process play an important role in the future success of the LED industry. Because for the LED industry, there are almost only a few companies supplying chemical materials, and the material suppliers cannot provide the overall market demand, so, the need to support the growth of the overall LED industry is the key. The market size of LED raw materials in 2013 reached 50. Sales of 0. 1 billion US dollars will reach 117 by 2018. 0. 1 billion US dollars, that is, the market size will double in the past five years. Through the four stages of LED manufacturing value chain, the application of chemical materials includes chip manufacturing, packaging, module manufacturing and lamp assembly. Therefore, when predicting the growth trend of LED industry, manufacturers or research institutions can first see some early trends through the growth model of LED chemical material revenue. The 2016 research report on substrate materials for LED in China pointed out that historically, LED was used in electronic applications (Such as display backlight) The demand for LED chemicals has driven the growth of demand. But now this market is relatively mature, so the demand in the general lighting field will become the center of the next wave of chemical and material growth. Among the four stages involved in LED manufacturing, the value chain for the great demand for chemical and material products is in the final stage, that is, the assembly of lamps. The market scale and development prospect of LED materials are analyzed. Therefore, when the price of LED shows a downward trend in all stages of the value chain, the stage with large price pressure is also the stage of lamp assembly. Therefore, whether chemical and material manufacturers can provide innovative products to reduce the cost of LED manufacturers becomes the key. In addition, all operators in the market must use LED to provide a different space design from traditional lighting to create opportunities. After all, LED lighting lamps are different from traditional lamps. LED light sources do not need to be designed around a replaceable bulb. The possibility of innovative design and material selection will lead to business opportunities different from previous lighting technologies.
