LEDs were only used as indicator lights before the 1990s. After the 1990s, the development of high-bright InGaAlP quaternary red, yellow and GaN blue and white devices was successfully developed, and LED applications began to be converted from indications to illumination. The main application areas include LED display, traffic signal, landscape lighting, mobile phone application, automotive lamp, LCD display backlight. 1. LED technology continues to make breakthrough progress in 2017. Technology is a powerful driving force for the rapid development of the LED industry. On the world stage and the hard air. Under the increasingly fierce competition in the market economy, the LED industry can only achieve better development if it continuously promotes technological innovation. Looking back on 2017, many technologies in the LED industry have achieved breakthrough development, and the market scale of the LED industry is constantly expanding. Second, the global and domestic LED industry market growth rate has slowed down In 2010-2015, the global LED industry market scale showed a steady increase trend, but in recent years, the growth rate showed a downward trend. In the past five years, the year-on-year growth in 2012 was the largest, reaching 44.96%. In 2017, the LED industry market was about 648.074 billion US dollars, an increase of 13.42%. Forward-looking Industrial Research Institute predicts that the growth rate of the LED industry market will remain at around 12% in the next five years. In 2010-2017, the market scale of China's LED industry showed a rapid growth trend. In 2017, the industry scale was 522.8 billion yuan, a year-on-year increase of 14.24%, and the industry grew at a faster rate. Looking ahead, China's LED industry is closely related to the world, and the growth rate will further slow down in the future, which is estimated to remain at around 13%. Third, the global LED products are currently based on mobile phone equipment. In the future, LEDs can only be used as indicator lights before the 1990s. After the 1990s, high-intensity InGaAlP quaternary red, yellow and GaN systems are highlighted. The development of blue and white light devices has been successful, and LED applications have begun to be converted from illumination to illumination. The main application areas include LED display, traffic signal, landscape lighting, mobile phone applications, automotive lights, LCD display backlights, general lighting and so on. At present, LED products are widely used in mobile phones, and are the most important application areas of LED products, accounting for about 31% of the total market demand. Generally, each mobile phone needs 10-20 LED products, which are used in the mobile phone keyboard, display backlight and camera flash. The penetration rate of LED products in the mobile phone market has stabilized. In the future, the growth of LED products for mobile phones will be directly affected by mobile phone sales. Since 2014, the main growth driver for the growth of the global LED industry has come from lighting applications, accounting for 50%. The advancement of LED lighting technology and the decline in prices have made LEDs into the field of lighting a reality. In 2017, the price of LED bulbs of international lighting manufacturer Philips further dropped to 5-7 US dollars, and OSRAM also seized the market with less than 7 US dollars. Because the luminous efficiency is higher than the energy-saving lamp, the price is lower than the energy-saving lamp, and the life is longer than the energy-saving lamp, the LED lighting product has become a powerful substitute for the energy-saving lamp. In the face of the trend of falling prices, global LED companies are looking for a segment of the field. Key enterprises are moving towards the high end of the value chain, strengthening innovation and research in automotive lighting, plant lighting, intelligent lighting and other sub-sectors, providing alternative lighting solutions for different application environments. Furthermore, the global phase-out of incandescent bans has entered a critical period. From the time point of view, the major countries and regions that eliminated incandescent lamps in 2013 will enter the window of 75W, 60W, 40W phase-out; from the perspective of coverage, the United States, Canada, Mexico, Brazil, Argentina, the United Kingdom, Australia, the European Union, Japan South Korea, China and other countries and regions have entered the prohibition and elimination period of incandescent lamps, which greatly stimulated the replacement and use of new light sources in 2014, and accelerated the promotion of LED lighting. The United States, the European Union, South Korea, Japan, China, etc. have proposed a replacement process for LED lighting products. South Korea proposed to ensure that LED lighting products entered the general lighting market by 30% in 2015; Japan proposed a 50% replacement rate for LED lighting in 2015, and a 100% replacement rate for LED lighting products in 2020. LED certification, gradual revision and improvement of standards have made LED lighting enter a critical period of development in 2014, and policies have become a favorable guarantee for the development of LED industry. Overall, replacing traditional light bulbs will be the largest application market for LED lighting in the next few years. In 2017, the global LED lighting penetration rate reached 36.7%; forward-looking 2020 China's LED lighting penetration rate reached 60%-70%. The product structure gradually entered general-purpose home lighting from outdoor lighting and commercial lighting, and became the main driving force for the rapid growth of the LED industry. From the perspective of individual applications, including display lighting, commercial industrial lighting, outdoor lighting, indoor lighting, replacement of light bulbs, etc., it will be the most important application market for LED lighting in the next few years.
