LED, full name is LightEmittingDiode, Chinese name is "led". Its common physical form is led element, that is, the LED chip is placed on the lead plate connected with the power supply, and then sealed in a transparent epoxy box.
LED lighting industry refers to the electrical machinery and equipment manufacturing industry that can produce white light on the basis of LED chip technology, combined with the knowledge and technology of optics, thermology, power supply, machinery, electronics, efficiency management, precision production and other comprehensive disciplines to meet the lighting needs of people's daily life, such as work and study. At present, it mainly includes LED general lighting , led industrial lighting, LED landscape decoration lighting and other three specific application areas.
With the gradual improvement of technology, LED lighting is more and more widely used, the industrial development is accelerated, and the country has issued corresponding policies to promote development. As mentioned in the 13th five year plan for the development of semiconductor lighting industry released in July 2017, by 2020, China's key semiconductor lighting technologies will continue to break through, product quality will continue to improve, product structure will continue to be optimized, industrial scale will steadily expand, and industrial concentration will gradually increase, forming an LED lighting enterprise with more than 10 billion yuan of sales and cultivating 1-2 internationally renowned products Brand, about 10 domestic famous brands, etc.
With the advantages of long service life, low energy consumption, small light source volume, cost and relative economy, the penetration rate of LED has been continuously improved, and the scale of LED market has expanded rapidly. The data shows that since 2011, the scale of China's LED market has grown rapidly, from 154.5 billion yuan in 2011 to 550.9 billion yuan in 2017, with a compound growth rate of 23.6%, digital, visual, information and intelligent With the increasing demand for energy-based comprehensive intelligent government office and the continuous improvement of LED market scale, it is expected that the market scale will further grow in 2018, with a broad market prospect.
