LED downstream applications refer to finished products, including LED display, LED lighting products and a wide range of LED lighting products. At the same time, LED downstream also includes the development of some industries around, such as drive power, control system, hardware cabinet, control software and so on. LED Industry Chain Introduction Light-emitting diodes are referred to as LEDs and are made of compounds containing gallium, arsenic, phosphorus, and nitrogen. The upstream of the LED mainly refers to the upstream epitaxial chip, that is, the chip inside the LED lamp bead, and related materials, including: high purity gas, substrate material, MO source, alumina, phosphor, silica gel, gold wire, epoxy. Resin, silver glue and other materials. LED downstream applications refer to finished products, including LED display, LED lighting products and a wide range of LED lighting products. At the same time, LED downstream also includes the development of some industries around, such as drive power, control system, hardware cabinet, control software and so on. Epoxy resin production has increased steadily Epoxy resin is used in energy-saving LEDs must use important materials. Practice has proved that in addition to factors such as the quality of the chip itself, the choice of epoxy resin is also an important factor. Therefore, the LED packaging process must be based on different applications, choose different resins to ensure that the product meets the requirements of the use to the utmost. Epoxy resin is a polymer oligomerization which generally contains two or more epoxy groups and is composed of an organic compound such as an aliphatic, alicyclic or aromatic group and can form a useful thermosetting product by reacting with an epoxy group. body. In 2011-2016, China's epoxy resin production increased year by year. In 2016, China's epoxy resin production was about 1.43 million tons, an increase of 19.17%. The LED landscape lighting market is good. The goal of LED landscape lighting is to coordinate the landscape lighting with the landscape, adapt to the conditions of the scene, and adapt to the architectural characteristics to achieve a new level of landscaping. Landscape lighting is the traditional downstream market in the field of LED lighting. It is also the most mature branch of LED in the field of lighting. LED has successfully occupied a series of advantages such as high efficiency, low energy consumption, safety and reliability, convenient management and outstanding social and economic benefits. Absolute market share in landscape lighting. Landscape lighting is growing rapidly under the impetus of the government. It is mainly based on decorative lighting in public places such as streets and squares, which can save 70% of electricity. Common landscape lamps include: garden lights, walkway lights, buried lights, small spotlights, lawn lights, fast lanes, tunnel lights, wall lights, sculpture decoration, etc. According to the data of the Prospective Industry Research Institute's "2018-2023 China LED Lighting Industry Market Prospect and Investment Strategic Planning Analysis Report", the scale of China's LED landscape lighting market has been increasing year by year since 2011, and the market size in 2016 is about 44.5 billion yuan. Compared with the 40.9 billion yuan in 2015, it increased by 8.80%. LED street light develops rapidly LED street light is a semiconductor lighting lamp. It is a high-efficiency solid-state light source that emits light with weak electric energy based on the formation of a semiconductor PN junction. It is injected into the P region under a certain forward bias voltage and injection current. The electrons injected into the N region and the N-injected region are radiated and combined to emit photons, which directly convert electrical energy into light energy. It is a solid-state cold light source, which has the characteristics of environmental protection, no pollution, low power consumption, high luminous efficiency and long service life. Therefore, LED street lamps will become the best choice for energy-saving renovation of road lighting. As the main body of urban lighting, urban road lighting has experienced rapid growth along with the rapid development of urban construction in China. In 2008, China launched the Ten City Wanhao LED Application Pilot Demonstration Project, aiming to illuminate 6 million LED street lights in 21 demonstration cities nationwide by the end of 2011, with 1 million baht, 2 million baht and 300 in 2009-2011 respectively. Wan Hao, planning to build 5 million LED street lights in 2012. After the project started, more than ten cities including Beijing, Dongguan, Xiamen and Shijiazhuang have started to invest in the construction or renovation of LED street lights. Driven by the policy of ten cities and millions of cities, China's LED street lamp market will continue to grow. In recent years, the penetration rate (installation quantity) of China's LED street lamp market has been continuously improved. In 2016, the market size of China's LED street lamp is about 29 billion yuan. LED display applications are common LED display is a flat panel display, consisting of a small LED module panel. LED display screens are generally used to display various information such as text, images, video, and video signals. LED display is an early start in the entire LED industry chain, and has maintained rapid growth in the past decade. With the development of LED display technology, the corresponding product specifications and standardization are also at a high level. The data shows that in 2016, the overall scale of the national LED display application industry continued to increase. The total annual market volume of the whole industry was 33.2 billion yuan, an increase of 3.75% over the 2015 revenue of 32 billion yuan. The growth rate was slightly lower than that of 2015.
PPGI / PPGL Coil
PPGI/PPGL(prepainted galvanized steel/prepainted galvalume steel ) is also known as pre-coated steel,color coated steel, coil coated steel, color coated steel, prepainted steel sheet. The PPGI steel coil/sheet made of cold-rolled steel sheet and Galvanized Steel Sheet, subjected to surface pretreatment (degreasing, cleaning, chemical conversion treatment), coated in a continuous manner, and baked and cooled to form a product. Coated steel has light weight, beautiful appearance and good anti-corrosion performance, and can be directly processed.
Color coated steel coil is mainly divided into three parts: construction, household appliances and transportation. Building is generally used to build the roof, wall and door of industrial and commercial buildings such as steel structure workshop, airport,warehouse and freezer. Household appliances are used in the production of refrigerators and large air conditioning systems, freezers, toasters, furniture, etc. Transportation industry is mainly used for oil pan, automobile interior parts, etc.
PPGI is a product made of cold-rolled steel coil and (aluminum) Galvanized Steel Coil after surface chemical treatment, coating (roll coating) or composite organic film (PVC film, etc.), and then baking and curing. This product is produced by the manufacturer in coils on the continuous production line, so it is also called prepainted steel coil. It not only has the properties of high mechanical strength and easy forming of steel materials, but also has good decoration and corrosion resistance of coating materials.
