In recent years, the rapid development of China's LED industry, the infiltration rate continues to increase. According to the "LED lighting industry market forward-looking and investment strategic planning analysis report" released by the Industry Research Institute of Forward-looking Industry, the size of China's LED lighting industry has expanded by more than 255 billion yuan from 7.8 billion yuan, and the CAGR in 2009-17 is as high as 54.62%. The rapid expansion of the general lighting market is mainly due to the expansion of the general lighting industry and the improvement of the penetration rate of LED lighting. The penetration rate of LED lighting increased from 0.6% in 2010 to 42% in 2016.
National policies and energy-saving needs continue to push LEDs to replace traditional lighting. The Chinese government's policy of restricting incandescent lamps and supporting policies for LED lamps has promoted the development of the LED market. In 2011, the National Development and Reform Commission promulgated the “China's Roadmap for Phase-out of Incandescent Lamps”. Starting from 2011, every one or two years will be a phase, starting with the prohibition of imports and sales of high-power incandescent lamps, reducing the ban on ban sales, and finally achieving completeness. The purpose of the ban.
With the continuous maturation of LED technology, the luminous efficacy of LED lighting has been continuously improved, from 20 lm/W in 2003 to 160 lm/w in 2016, which is 6-10 times that of incandescent lamps, twice that of fluorescent lamps, and the light emitting angle is only One-third of fluorescent lamps, generally 18W LED lamps can replace the traditional 42W fluorescent tubes, 7W bulbs can replace the 50W incandescent lamps, the service life is much longer than the traditional lamps, the replacement of traditional lamps and more efficient The power-saving effect is even more obvious. On the other hand, the price of LED light sources has also been steadily declining. Now it has fallen to the price of traditional lighting fixtures. There is no resistance to replacement, and LED accelerated replacement has begun.
In July 2017, the national “13th Five-Year Plan for Development of Semiconductor Lighting Industry” was issued. According to the planning requirements, by 2020, the overall output value of the semiconductor lighting industry will reach 1,000 billion yuan, and the sales of LED lighting products will account for 70% of the total sales of the lighting industry.
Based on this assumption, the overall market size of China's LED lighting industry will reach 100 billion yuan in 2020, and the penetration rate of LED lighting industry will reach 70%. At the same time, based on the fact that LED general lighting accounts for a gradual increase in the market size of LED applications and that LED applications account for a gradual increase in the overall market size of LED, China's LED general lighting market is expected to reach 445.2 billion yuan by 2020.
Based on the characteristics of high luminous efficiency, easy control, long service life, and low pollution compared with traditional light sources, the LED lighting industry has been in a revolutionary era of replacement in recent years. From 2009 to 2015, the growth rate of global LED lighting penetration will continue unabated, steadily increasing from 1.5% to 27.2%, and the trend will continue. In 2016, the global LED lighting market has reached US$34.6 billion, with an increase of 15.80%, and the market growth rate remains high. Smart lighting is a general trend.
In the LED intelligent lighting system, the LED drive is a device that converts an AC power source (or a DC power source) into a cross current power source, and is a key component for realizing intelligent lighting. At present, the system controller that controls the power supply by the centralized controller through the bus (or wireless communication, power carrier) and constitutes the LED intelligent lighting control and drive system is the future development direction of the LED high-end lighting market.
