On March 18, 2015, Li Jiannan, the general manager of Everlight Lighting Co., Ltd., used digital analysis of the current industrial development status and future trends of the middle and lower reaches of Led. He mentioned that compared with the output value of 8.4 billion yuan and the growth rate of 17 in the epitaxial chip market in 2013, benefiting from the promotion of the proportion of domestic chips and the mature technology of flip-chip, high-power LED chips, the total output value of the epitaxial chip market reached in 2014. 12 billion yuan, an increase of 31. With the expiration of international major patents, the technology continues to mature and transparent, and the market share of mainland manufacturers continues to rise. In the field of lighting, the mainland factory chip continues its local advantage and becomes the absolute mainstream; in the backlight field, the mainland factory chip will be promoted. At present, there are more than 2,000 LED packaging enterprises in China. After years of fierce competition, the domestic LED packaging market is mature, and domestic enterprises have the same strength as international LED companies. In 2014, the packaging market also maintained steady growth. Compared with the output value of 47.3 billion in 2013, the output value of domestic led packaging this year is expected to reach 56.8 billion yuan, an increase of 19%. Observing the LED lighting market, the application value of LED package in the lighting market also showed a significant increase in 2014, especially the alternative light source products accounted for the highest proportion, followed by engineering, commercial, outdoor market growth is most significant. Compared with the increase in market output value, packaging technology has also matured, and medium power has gradually become the mainstream packaging method. The flip-chip structure of cob, cof technology and integrated packaged light engine have become the focus of manufacturers. With the outbreak of lighting applications, the mid-power LED package used in the city's products such as lamps, bulbs, downlights, and ceiling lamps remained in the mainstream market in 2015, accounting for 52% of the total package. In 2014, the scale of China's LED application industry reached 275.7 billion yuan, a year-on-year increase of 31. Among them, the city's lighting is still the main engine for the rapid development of the LED application industry. The output value of LED lighting in the city reached 108.2 billion yuan, a year-on-year increase of 73, maintaining a high growth trend. Accordingly, the proportion of LED indoor lighting output value to the overall application industry's output value has further increased to 39.2. The output value of outdoor lighting reached 14.7 billion yuan, a year-on-year increase of 22%. Among them, the street lamp industry mainly benefited from the high demand in the export market, and the output value of the street lamp industry achieved steady growth throughout the year. In 2014, the output value of landscape lighting, display and backlight industry was 45.7 billion yuan, 28 billion yuan and 25.1 billion yuan, respectively, which increased by only 9,6,4 respectively. The landscape and display screen were affected by factors such as government change. The development is flat, and the rapid slowdown of the backlight is caused by the saturation of the LED penetration rate and the slow growth of the market. Special lighting such as led explosion-proof lamps, led medical, led plant lights and other special lighting scale reached 9 billion yuan, an increase of 44, a noteworthy. Finally, he concluded that the upstream chip market, industrial concentration and bargaining power. In the midstream market, the expansion of production continues, which will intensify the fierce competition in the industry. The scale advantage has not yet been formed, the market is still scattered, there is no patent advantage, and there is no added value. In the downstream application market, the market competition is as intense as the packaging industry, and there are many options. The LED device is still the buyer's market. The e-commerce channel will be one of the main channels for terminal sales. Under the support of indoor lighting in the LED industry, it will maintain rapid growth. The LED enterprises will be in a fierce competitive landscape. The international giants will survive in a more focused manner, reducing the investment in the city and investing in professionalism. And the city is bright.
