Home intelligent lighting is an important part of the smart home category. Since Apple's iPhone, iPad, Android phones and tablets are becoming more and more popular, intelligent lighting is getting closer and closer to the homes of ordinary consumers. Products from smart bulbs to smart lamp holders and smart control boxes have been exposed, Among them, the emergence of Philips hue bulb has opened the veil of the advantages of intelligent lighting scene change of ordinary families for the first time, and opened a new chapter of intelligent home lighting with low consumption, environmental protection, dimming and color matching. Since entering the Chinese market in the 1990s, the development of intelligent lighting industry has been in a slow development trend due to the influence of market consumption awareness, market environment, product price, promotion and other aspects. In recent years, with the rapid development of the national economy, especially the rapid development of the real estate industry, the domestic intelligent lighting industry has developed rapidly, and all kinds of intelligent lighting products have been put on the market. The scale of China's intelligent lighting market has grown from 4.9 billion yuan in 2005 to 13.7 billion yuan in 2009. The capacity of China's advanced intelligent lighting market is expected to reach US $200 billion within five years. Since the 1990s, foreign intelligent lighting system manufacturers have invested and built factories in China. In the 21st century, domestic intelligent lighting manufacturers and businesses have also mushroomed and developed rapidly. Dozens of enterprises of different sizes have emerged, such as Swiss franc, high standard lighting, Tsinghua Tongfang, SOBO and so on. The domestic intelligent lighting industry has entered a new stage of development. However, due to the early start of intelligent lighting systems of foreign brands and the strong R & D strength of multinational enterprises, their products are at the forefront of the intelligent lighting industry in terms of creativity and quality. The domestic intelligent lighting market is the world of foreign brands. Foreign brands account for more than 90% of the domestic market share of large public buildings (such as stadiums, office buildings, hotels, etc.) and more than 70% of the home intelligent lighting system, and domestic enterprises in the industry can not compete with them. Compared with traditional lighting, intelligent lighting can achieve the purpose of safety, energy saving, comfort and efficiency. Therefore, intelligent lighting has good development prospects in the field of home, office, business and public facilities. China's intelligent lighting market is not mature. The application fields of intelligent lighting are mainly concentrated in business and public facilities. Intelligent lighting is widely adopted and used in hotels, exhibition venues, municipal engineering and road transportation; In addition, office buildings and high villa projects also use intelligent lighting. With the development of domestic intelligent lighting R & D and production technology and the increase of product promotion, the application of intelligent lighting in the field of home is expected to be popularized. In the recent research report "analysis of intelligent lighting wireless transmission protocol", China Electronic Information Industry Development Research Institute (CCID), China's Technology Industry Research Institute, has identified Jennet IP as the ideal wireless communication protocol for the next generation of emerging intelligent applications, indicating that this technology will help to further realize the concept of Internet of things (IOT). Jennet IP, developed by NXP semiconductors N.V., is an enhanced 6LoWPAN network layer with the characteristics of convenient use, high security and low cost. The protocol is designed for ultra-low power networks based on IEEE 802.15.4, and can be used in both residential and industrial applications. According to CCID Consulting, a subsidiary of CCID, the substitution effect of LED in the traditional lighting market has greatly increased the demand for semiconductor lighting. CCID's research report shows that ultra-low power intelligent lighting system is expected to become one of the main development trends in the lighting industry. It is also found that compared with other wireless communication protocols, IP based Jennet IP improves the performance and functions required for seamless internet of things communication.
