As the LED industry chain analysis in 2018, this industry is developing in great situation
LED industry chain introduction
Light-emitting diodes are abbreviated as LEDs and are made of compounds containing germanium, arsenic, phosphorus, nitrogen, and the like. LED upstream mainly refers to the upstream epitaxial chip, which is the chip inside the LED lamp beads, 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 displays, LED lighting products and a wide range of LED lighting products. At the same time, the LED downstream also includes the development of some of the surrounding industries, such as driving power, control systems, hardware boxes, control software and so on.
Epoxy resin production increases steadily
Epoxy resins are important materials that must be used in energy-saving LEDs. Practice has proved that, in addition to factors such as the quality of the chip, the choice of epoxy resin is an important factor in determining the performance of the LED. Therefore, the LED packaging process must be based on different occasions, select different resins in order to ensure that the product meets the maximum use requirements.
Epoxy resin generally refers to a polymer oligomer containing two or more epoxy groups, and an aliphatic, alicyclic, or aromatic organic compound as a skeleton and capable of forming a useful thermosetting product through the reaction of epoxy groups. body. In 2011-2016, China's epoxy production has increased year by year. In 2016, China's output of epoxy resin was approximately 1.43 million tons, an increase of 19.17% year-on-year.
LED landscape lighting market is good
The goal of LED landscape lighting is to harmonize the landscape lighting with the landscape. Because of the “scape”, due to the construction characteristics, it is 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 due to its high efficiency, low energy consumption, safety, reliability, convenient management, and outstanding social and economic benefits. Absolute market share in landscape lighting.
Landscape lighting is rapidly growing under the impetus of government forces. It is mainly based on decorative lighting in public places such as streets and squares, which can save 70% of electric energy. Common landscape lamps include: garden lights, footpath lights, buried lights, small spotlights, lawn lights, fast lane lights, wall lights, sculpture decoration.
Prospective Industry Research Institute "China's LED lighting industry market prospects and investment strategic planning analysis report 2018-2023" data show that since 2011, China's LED landscape lighting market continues to grow year by year trend, the market size in 2016 is about 44.5 billion yuan, Compared to 2015, the figure was 40.9 billion yuan, an increase of 8.80%.
LED street lamp develops rapidly
The LED street lamp is a semiconductor lighting lamp, which is an efficient solid-state light source that is formed based on a semiconductor PN junction and emits light with weak electric energy. Under certain forward bias voltages and injection currents, holes injected into the P region and N are injected. After the electrons in the area are diffused into the active area, they are irradiated and recombined to emit photons, converting the electrical energy directly into light energy. It is a kind of 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 road lighting energy-saving reconstruction.
As the main body of urban lighting, urban road lighting has been rapidly growing 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 light 6 million LED street lights in 21 model cities nationwide by the end of 2011, and 1 million and 2 million respectively in 2009-2011. , 3 million baht, planning to build 5 million LED street lamps in 2012. After the project was launched, Beijing, Dongguan, Xiamen, Shijiazhuang and more than a dozen cities have begun investing in new or retrofit projects for LED street lamps.
Driven by the "ten cities, ten thousand" policy, China's LED street lamp market will continue to grow. In recent years, the penetration rate (number of installations) of LED street lamps in China has been continuously increasing. In 2016, the market size of China's LED street lamps was about 29 billion yuan.
LED display applications are common
The LED display is a flat panel display consisting of a small LED module panel. LED display is generally used to display text, images, video, video signals and other information. The LED display is an early product in the entire LED industry chain and has maintained rapid growth in the past ten years. With the rapid development of LED display technology, the corresponding product specifications and standardization are also at a relatively high level.
The data shows that in 2016, the overall scale of the LED display application industry in China continued to increase. The total annual industry market totaled 33.2 billion yuan, an increase of 3.75% from the 32 billion yuan in 2015. The growth rate was slightly lower than that of 2015.
