1.Introduction to LED industrial chain
LED, for short, is made of compounds containing gallium, arsenic, phosphorus and nitrogen. The upstream of LED mainly refers to the upstream epitaxial chip, which is the chip inside the LED lamp bead, and some related materials, including: high purity gas, substrate material, MO source, alumina, phosphor, silica gel, gold wire, epoxy resin, silver glue and other materials.
Downstream application of LED refers to finished products, including LED display, LED lighting products and various LED lighting products. At the same time, the downstream of LED also includes the development of some surrounding industries, such as drive power, control system, hardware box, control software and so on.
The production of epoxy resin increased steadily
Epoxy resin is an important material for 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 in determining the performance of LED. Therefore, the LED packaging process must be based on different occasions, the selection of different resins, to ensure that the product to the maximum extent to meet the use requirements.
Epoxy resin generally refers to the polymer oligomer containing two or more epoxy groups, which is composed of aliphatic group, aliphatic ring group or aromatic group and can form useful thermosetting products through the reaction of epoxy groups. From 2011 to 2016, the production of epoxy resin in China increased year by year. In 2016, the production of epoxy resin in China was about 1.43 million tons, a year-on-year increase of 19. 17%.
LED landscape lighting market is good
The goal of LED landscape lighting is to harmonize landscape lighting with landscape, to achieve a new level of beautification due to "landscape" and architectural characteristics. Landscape lighting is the traditional downstream market of LED lighting field, and it is also the most mature branch of LED in lighting field so far. LED has successfully occupied the absolute market share in landscape lighting by virtue of its high efficiency, low energy consumption, safety and reliability, convenient management, prominent social and economic benefits and a series of advantages.
2.Landscape lighting, driven by the government, is growing rapidly. It is mainly used to decorate streets, squares and other public places, saving 70% of the electricity. Common landscape lamps and lanterns include: garden lights, pedestrian lights, buried lights, small spotlights, lawn lights, fast lane tunnel lights, wall lights, sculpture decoration, etc.
According to the "2018 -- 2023 China LED lighting industry market outlook and investment strategic planning analysis report" by qianzhan industry research institute, the market size of LED landscape lighting in China has been growing year by year since 2011. In 2016, the market size was about 44.5 billion yuan, an increase of 8 percent compared with 40.9 billion yuan in 2015. 80%.
