With the continuous popularization of the concept of green, energy-saving and low-carbon life, energy-saving and environmentally-friendly products have been increasingly valued by the society. The green lighting represented by LED has begun to penetrate the traditional market with its outstanding advantages, and has set off a new field in the field of lighting. revolution. According to McKinsey's forecast, by 2020, the global general lighting industry sales revenue will reach 82.505 billion euros, of which LED lighting products sales revenue will reach 56.928 billion euros, accounting for 69, 2011-2016 and 2016-2020 global lighting industry. General lighting sales revenue growth rate is expected to be 6 and 3, of which LED lighting products sales revenue growth rate of up to 45 and 15. Lighting industry development is mainly affected by government policies, manufacturing costs and end-user purchase willing factors . Before 2012, the LED lighting industry developed slowly, and there was no explosive growth. The main reason is that LED lighting products are highly customized and cannot meet the standardization of traditional lighting product specifications, which makes it difficult to reduce manufacturing costs and create certain obstacles to its large-scale promotion. . In 2013, due to the dual role of light source cost reduction and policy promotion, the penetration rate of LED lighting products increased rapidly, and the market sentiment continued to increase. On the one hand, due to technological advancement and scale production, the cost of component packaging and application has dropped rapidly, resulting in the sales price of LED lighting products gradually approaching the price of traditional lamps. According to the US Department of Energy, the cost of LED chips will be reduced by 2020 compared with 2013. 82, LED package cost reduction 78, 60 watts level LED chip cost will be reduced 66, the cost reduction will be one of the main reasons to promote the penetration of LED lighting products. On the other hand, the continuous investment of the government's resources and the formulation of relevant policies have also promoted the development of the market. In 2012, the world's first wave of incandescent lamps was banned. For example, South Korea and Japan entered the stage of total ban, and in 2014, the EU, the United States, China and other places will also enter the mainstream incandescent lamp ban phase, which will once again increase the LED lighting penetration rate. At the same time, governments have introduced incentive policies, such as the Japanese government's plan to redeem LED products. The South Korean government has launched plans to support the promotion of semiconductor lighting in roads and indoor lighting. Major cities in Australia, Argentina, Colombia and India have opened LED streetlights. Project, the US Energy Star program will include LED lighting products in the subsidy catalog; China has placed LED lighting in key areas and priority themes. As of 2012, it has allocated a total of 4.175 billion yuan of financial funds to support the development of energy-saving and environmentally-friendly lighting industry. In summary, with the ban on the sale of incandescent lamps and the promotion of LED lighting in major countries and regions around the world, the lighting industry will usher in a turning point in development.
