First, the continuous growth of population has led to the continuous increase of primary energy consumption; secondly, due to the different economic development of various countries, different energy consumption growth patterns have been created. Developed countries have entered a post-industrial society and their economies have shifted to an industrial structure with low energy consumption and high output. development, the growth rate of energy consumption is significantly lower than that of developing countries; third, the regional energy consumption structure is significantly different; finally, the uncontrollability of the epidemic and political reasons has increased the pressure on energy trade and transportation.

At the same time, the global climate change is becoming more and more serious, and the natural disasters caused by the climate are becoming more and more severe, and the people's awareness of environmental protection is also increasing day by day. As a result, a diversified, clean, efficient, globalized and market-oriented "green economy" has become a breakthrough to break the energy predicament.

In the 1990s, a global trade pattern of two continents was formed. First, the free trade agreement between the primary and tertiary industries in North America led by the United States, followed by the integration of the European Union’s economic market, and finally the World Trade Organization (WTO) established.

After the formation of the three circles, the foundation of world free trade was laid and the pattern of regional monopoly was formed. The "Kyoto Protocol" signed by various countries in 1997 further promoted the development goals and tasks of green lighting, and encouraged and supported the research and innovation of LED lighting technology.

In 2007, the subprime mortgage crisis and anti-dumping policy in the United States hit the lighting industry, which was just in the development stage, and caused a sharp drop in exports. However, Chinese lighting companies tried their best to introduce advanced equipment and R&D new technologies. From 2013 to 2016, the domestic replacement rate of LED chips increased, and the cost performance of small and medium power products was greatly improved, finally catching up with the second round of LED chips. As a result, China is gradually realizing the localization of the entire industry chain from OEM.

In the early 1990s, the US National Environmental Protection Agency proposed the concept of "green lighting". It includes four indicators of high efficiency, energy saving, environmental protection, safety and comfort. High-efficiency and energy-saving, as the name implies, ensures that the least amount of electric energy is consumed under the condition of sufficient lighting, thereby reducing the pollutant discharge of the power plant and achieving the purpose of environmental protection. The light is clear and soft and does not produce ultraviolet rays, and the anti-halation and light pollution are for the purpose of safety and comfort.

From a macro perspective, the specific implementation of green electricity consumption can be divided into two aspects: reducing energy consumption on the one hand, and developing new technologies and products on the other hand. Replacing incandescent lamps with LEDs nationwide can save about 41.67Mtce (2018), which shows that its energy saving effect is remarkable. With the development of technology, today's LED lighting has developed to the late stage of maturity, and it is inevitable to develop new applications, such as the cross-industry combination of smart lighting, such as the combination of lighting systems and big data in different application scenarios.

From a micro perspective, the speed at which an enterprise eliminates old production capacity, develops new energy-saving products, and the feasibility of long-term goals determines its future development. With the continuous advancement of technology and the ever-changing market, for the LED lighting industry, it is easy to be eliminated by the times if it sticks to the rules and does not cut the meat in time or even pay attention to the changes in market expectations. Speed is efficiency, and sometimes it is the key to winning. This requires companies to keep abreast of the world situation and the government's industrial planning, so as to make timely or even advanced decision-making adjustments.
