Lighting engineering refers to the use of natural light or artificial lighting systems in indoor spaces and outdoor spaces such as roads, plazas, scenic spots, parks, buildings, etc. through specific design, technology and engineering to meet the illuminance, brightness and color rendering of the illuminated surface. And subjects with specific visual effects. Lighting engineering involves optical, electrical, aesthetic, architecture, computer science and other disciplines. It is a comprehensive and systematic project. The lighting engineering industry is a typical technology and capital-intensive industry.

In recent years, the core technology of China's LED lighting products has achieved rapid development, and the gap between the international level and the international level has been shrinking; LED lighting products have been widely used in urban landscape lighting, road lighting, commercial lighting, and application technology has matured; The market for LED lighting products continues to expand, and application scenarios continue to increase. LED lighting has developed into the mainstream of the lighting industry. At the same time, the introduction and implementation of the national green lighting project and related policies directly promoted the rapid development of the LED lighting market. LED lighting products will maintain a strong development momentum and gradually replace other existing lighting products.

With the continuous development of China's economy and the improvement of people's living standards, the domestic LED lighting engineering market has maintained rapid growth. According to the National Semiconductor Lighting Engineering R&D and Industry Alliance data, the market size of China's LED application industry has reached 608 billion yuan in 2018, while LED landscape lighting accounted for 16.50% of the LED application industry market, and the LED landscape lighting market reached 10.32 billion yuan. The growth rate was 26.01% year-on-year, and the growth rate was higher than the entire LED application market. It is expected that the LED landscape lighting market will exceed 150 billion yuan in 2020.
