LED is dominated by monochromatic light at the beginning. Although the power is small and the price is high, it has high reliability, strong controllability and small volume. Therefore, the first market to emerge is electronic device indicator light. With the gradual development of LED lighting fixtures, LED lighting fixtures have gradually replaced some traditional light source products in public places such as lighting engineering auxiliary lighting. In the 2009 s, LED lamps began to enter the main lighting popularization in developed countries. The market has certain recognition and acceptance of LED lamp products. The Environmental Protection, small size, high reliability and other characteristics of LED lamps are gradually highlighted. With the gradual development of LED lighting fixtures, LED has gradually replaced some traditional light source products in public places such as lighting engineering auxiliary lighting. In the 2009 s, LED began to enter the main lighting popularization in developed countries. In commercial application places with high electricity charges and long use time, LED lamps have quickly become the new favorite of the market. As the use of LED lighting lamps, LED market development is divided into several stages. Stage, LED lamps replace the acceptance stage. This stage refers to the early development of LED lamps, which mainly reflects its high luminous efficiency (Low energy consumption), The characteristics of long life. Because the price is high, it is mainly the commercial market at this stage. Customers have a process of acceptance, the first is the transition and acceptance of usage habits and appearance. Under the same usage as the traditional light source, the specific characteristics of LED lamp, such as electricity saving and longevity, make the market easy to accept its relatively high price. Especially in commercial occasions. All manufacturers are fighting for quality and price advantages. The second stage, LED lamp utility model stage. On the basis of the previous stage, the market has certain recognition and acceptance of LED lamp products. The Environmental Protection, small size, high reliability and other characteristics of LED lamps are gradually highlighted. A series of products developed from this, which are completely different from traditional light source applications, will become popular. There will be a larger and wider development space in the lighting industry. The light source is no longer just a lighting effect, and its changeability makes it more appropriate for people's work and life. All manufacturers are fighting for the advantages of design and application. The third stage is the intelligent control stage of LED lamps. With the development of new technologies such as the internet of things, LED, as a semiconductor industry, will also catch up with this high-speed train and give full play to its high controllability. From home to office building, from road to tunnel, from car to walk, from auxiliary lighting to main lighting, LED lighting system with intelligent control will bring higher level of service to human beings. The LED lighting industry will also go through the process from making products to designing products to providing overall solutions.
