Analysis of LED industry chain in 2018, the development situation of upstream and downstream is good

LED downstream applications refer to finished products, including LED display screens, LED lighting products and various LED lighting products. At the same time, the LED downstream also includes the development of some surrounding industries, such as driving power supply, control system, hardware box, control software, etc. LED industry chain introduction, LED for short, is made of compounds containing gallium, arsenic, phosphorus, nitrogen, etc. The upstream of LED mainly refers to the upstream epitaxial chip, that is, the chip inside the light emitting diode lamp bead, and some related materials, including: high purity gas, substrate material, MO source, alumina, fluorescent powder, silica gel, gold wire, epoxy resin, silver glue and other materials. LED downstream applications refer to finished products, including LED display screens, LED lighting products and various LED lighting products. At the same time, the LED downstream also includes the development of some surrounding industries, such as driving power supply, control system, hardware box, control software, etc. The steady increase in the output of epoxy resin is an important material that must be used in energy-saving LED. Practice has proved that in addition to the quality of the chip itself, the choice of epoxy resin is also an important factor that determines the performance of LED. Therefore, the LED packaging process must select different resins according to different use occasions to ensure that the products meet the use requirements to the greatest extent. Epoxy resin refers to a polymer oligomer that contains two or more epoxy groups, takes aliphatic, alicyclic or aromatic organic compounds as the framework, and can form useful thermosetting products through the reaction of epoxy groups. 2011- In 2016, the output of epoxy resin in China increased year by year. 2016 China epoxy resin yield about for 1. 43 million tons with than growth 19. 17. Good LED landscape lighting market the goal of LED landscape lighting is to coordinate landscape lighting and landscape, and to achieve a new level of beautifying the environment due to the scenery and architectural characteristics. Landscape lighting is a traditional downstream market in the field of LED lighting, and it is also a mature branch of LED in the field of lighting so far, LED has successfully occupied the market share of landscape lighting with a series of advantages such as high efficiency, low energy consumption, safety and reliability, convenient management and outstanding social and economic benefits. Landscape lighting promotes rapid growth in government power, mainly focusing on decorative lighting in public places such as streets and squares, which can save 70% of electric energy. Common Landscape lamps include: garden lamps, footpath lamps, underground lamps, small spotlights, lawn lamps, Fast Lane ground lamps, wall lamps, sculpture decorations, etc. Prospective Industry Research Institute, 2018- According to the data in the analysis report of China's LED lighting industry market prospect and investment strategic planning in 2023, the scale of China's LED landscape lighting market has maintained a trend of increasing year by year since 2011, with a market size of about 44. 5 billion yuan in 2016, compared with the 40. 9 billion yuan in 2015, it increased by 8. 80. LED street lamps are developing rapidly. LED street lamps, namely semiconductor lamps, are high-efficiency solid-state light sources based on semiconductor pn junctions that can emit light with weak electric energy, under a certain forward bias voltage and injection current, holes injected into the P region and electrons injected into the N region emit photons through radiation recombination after diffusing to the active region, direct conversion of electrical energy into light energy. It is a solid-state Cold light source with the characteristics of environmental protection, no pollution, low power consumption, high light efficiency and long service life. Therefore, LED street lamps will become a good choice for energy-saving renovation of road lighting. As the main body of urban lighting, urban road lighting has achieved rapid growth with the rapid development of urban construction in our country. China launched a pilot demonstration project on LED application in 10 cities in 2008, with the goal of lighting 6 million LED street lamps in 21 demonstration cities across the country by the end of 2011, 2009- In 2011, there will be 1 million, 2 million and 3 million respectively, and 2012 LED street lamps will be planned and built in 5 million. After the start of the project, more than ten cities including Beijing, Dongguan, Xiamen and Shijiazhuang have begun to invest in the new construction or renovation of LED street lamps. Driven by the policy of ten cities and ten thousand lamps, China's LED street lamp market will continue to grow. In recent years, China's LED street lamp market penetration rate (Number of installations) With continuous improvement, the market size of LED street lamps in China will be about 29 billion yuan in 2016. LED display screen application common LED display screen is a flat panel display, composed of small LED module panels. LED display screen is generally used to display various information such as text, image, video, video signal, etc. LED display screen is a product that started earlier in the whole LED industry chain and has maintained rapid growth in recent ten years. With the development of LED display technology maturing day by day, the corresponding product specifications and standardization are also at a higher level. Data show that in 2016, the overall scale of the National LED display application industry continued to increase, with the total annual market of 33. 2 billion yuan, up 32 billion from yuan in 2015. 75, the growth rate is slightly lower than 2015.
