Since the initial stage of LED is dominated by monochromatic light, although its power is small and its price is high, its reliability is high, its controllability is strong, and its volume is small. Therefore, the first emerging market is the indicator light of electronic devices. For example: traffic model lights. With the gradual development, LED lighting has gradually replaced some traditional light source products in public lighting such as lighting auxiliary lighting. With the luminous efficiency of white LED tips and the price drop, LED in the electronic products backlight (such as: mobile phones, LCD TVs, etc.), automotive lighting and other industries occupy an increasing share. In 2010, LED began to enter the main lighting in developed countries. In particular, LED lamps have quickly become the darling of the market in commercial applications where electricity costs are high and usage time is long. It can be inferred that as a lighting application, the LED market is divided into several stages. The first stage, alternative acceptance stage. This phase refers to the early development of LED, mainly reflecting its high luminous efficiency (low energy consumption), long life characteristics. Because of the high selling price, this is mainly the market for commercial lighting at this stage. The appearance and interface of some traditional light sources are the “laws†that they must abide by at the beginning. The customer has a process of acceptance. The first is the transition and acceptance of usage habits and appearance. Under the same usage conditions as conventional light sources, the LED's power saving and longevity characteristics make it easy for the market to accept its relatively high prices. Especially in commercial applications. All manufacturers fight is the quality and price advantage. The second stage is the utility model stage. On the basis of the previous stage, the market has a certain recognition and acceptance of LED products. LED's environmental protection, small size, high reliability and other features have gradually emerged. A series of products that are completely different from traditional light source applications will be developed. For example: a variety of new light source integrated lighting, high-reliability explosion-proof lights, inductive unattended lights and so on. The lighting industry will have a bigger and broader development space. The light source is no longer merely used for illumination. Its change makes it more appropriate for people's work life. Each manufacturer fights for design and application advantages. The third stage, intelligent control stage. With the development of new technologies such as the Internet of Things, LED, as a semiconductor industry, will also take this high-speed train and demonstrate its high controllability. From home to office buildings, from roads to tunnels, from cars to walks, from auxiliary lighting to main lighting, LED lighting systems with intelligent controls will bring higher levels of service to humans. The LED industry will also go from making products to designing products to providing overall solutions. In summary, the competition in the LED industry will change from manufacturing to service industry, and will change from product manufacturing to program production. Its broad characteristics will create a broad market prospect. And will interweave into unprecedented industries.
