As a new generation of lighting source and green light source, LED lighting is widely applied in fields such as green lighting, healthy lighting, smart cities, and smart homes. In recent years, the government has continually introduced proactive policies, including the "14th Five-Year Plan for National Urban Infrastructure Construction" and the "Implementation Plan for Carbon Peaking in Urban and Rural Construction," among others, which benefit the development of the LED lighting industry. These policies emphasize the promotion of energy-saving, green, and efficient light sources in urban, home, and educational scenarios, supporting carbon peaking and carbon neutrality goals. This has significantly boosted confidence in industry development and created a favorable policy environment for the sector.

In the context of growing global environmental concerns, with an increasing focus on energy conservation, emission reduction, and carbon neutrality, the trend of replacing traditional light sources with LEDs has intensified. As a representative of high-efficiency energy-saving technology, LED lighting plays a significant role in reducing energy consumption and greenhouse gas emissions, contributing to global energy-saving and emission-reduction goals. Additionally, the long lifespan of LEDs reduces the frequency of lighting equipment replacement, minimizing resource use and waste generation, aligning with sustainable development and carbon neutrality goals. The widespread adoption of LED lighting is not only about promoting advanced lighting technology but also a key step in supporting global sustainability and environmental protection.

With advancements in LED technology and decreasing costs, governments worldwide have introduced policies to encourage the replacement of traditional light sources with LEDs. These policies include banning incandescent lamps and establishing energy efficiency standards to encourage businesses and individuals to adopt LED lighting. As a result, the penetration rate of LED lighting has been steadily increasing. In China, since the introduction of favorable policies such as the "Roadmap for the Phased Elimination of Incandescent Lamps," the penetration of LED lighting has risen steadily, surpassing global levels. By 2021, China's LED lighting penetration rate reached 80%. Globally, LED lighting accounted for just 1.8% of the market in 2012, but by 2021, the global average penetration had increased to 66%. It is expected that the global penetration rate will reach 75.8% by 2025, with higher demand for replacement in overseas markets.
