After several years of low price competition and industry integration, LED lighting industry has entered a mature period. The price performance ratio of products has been greatly improved, the penetration rate of application market has been improved, and the traditional application market has gradually saturated. The competitive advantage of an enterprise is gradually shifting from its scale and product cost to its product and technology capabilities, and the added value of its products is increasingly prominent.
With the rise of the Internet of things, LED lighting is moving towards high value digital lighting with small-scale networking. Intelligent system can collect users, environment and other information through various sensors, analyze data, and adjust equipment. The integration of personalized, people-oriented intelligent lighting is becoming the focus of future industrial development.
In 2017, with the development of technology, the maturity of products, the active promotion of manufacturers and the popularization of relevant concepts of intelligent lighting, the global intelligent lighting market entered a high-speed development stage, with a market scale of nearly 4.6 billion US dollars and an annual growth rate of 95%. It is expected that the market will continue to grow in the next few years, and the global intelligent lighting scale will reach 13.4 billion US dollars by 2020.
As the access port of smart city, smart lighting has its inherent advantages, and major manufacturers actively layout
Smart lighting can not only obtain higher profit margin, but also an excellent access point for smart city. With the continuous development of the city, there are more and more challenges in energy consumption, infrastructure construction and other aspects. By 2030, it is estimated that the global urban population will account for 60%, the urban energy consumption will account for about 75% of the global total energy consumption, and the lighting will account for nearly 40% of the total urban energy consumption. As an important part of smart city, smart lighting has inherent advantages in the number of Internet of things access points, and governments around the world are also actively advocating the construction and development of smart city.
The lighting giants, including Philips and OSRAM, have also laid out this market. In 2015, Philips Lighting participated in the pilot project of intelligent Internet road lighting in Los Angeles, deployed the Philips citytouch intelligent Internet road lighting management system in Los Angeles. In 2017, Philips Lighting introduced the city touch flex intelligent Internet road lighting system into China, and made new progress with China Telecom The combination of Internet of things (NB IOT) technology and Tianyi cloud technology services can access various smart city applications, including urban emergency system, traffic signal management system, security monitoring system, etc., and jointly accelerate the construction of China's smart city.
In January 2018, OSRAM released a new smart city central management platform, Symphony TM (an open platform system integrating software and hardware). In addition to lighting management, it can also realize a multi-functional integrated intelligent city central management platform for integrated management of urban security, environment, energy and communication. This will help city managers improve efficiency, reduce costs and promote the development of smart cities.
In addition, Chinese manufacturers such as Feile audio and Zhouming technology are also vigorously promoting smart street lamps. At present, they mainly undertake relevant projects of the Chinese government. Feile audio has signed strategic cooperation agreements with more than 20 cities and plans to build a total investment scale of about 4 billion RMB "smart cengong" project with cengong county government of Guizhou Province.
Continuous change of communication technology and diversified development trend
With the development of Internet of things and intelligent lighting, Dali, ZigBee, Bluetooth, Wi Fi, Lora, Nb IOT, sigfox, Z-Wave, enocean and other communication technologies have emerged in the market.
In the field of indoor lighting, although there are many wireless communication protocols to be applied, Dali cable technology specially designed for lamps still occupies the highest market share at present. The system based on Dali protocol has distributed intelligent modules, each module has digital control and communication capabilities, address and lighting scene information are stored in the memory of each Dali module. Dali module uses Dali bus to carry out digital element communication, transfer instructions and state information, and realize the functions of light switch, dimming control, system setting, etc.
At present, the most advantage of wired control technology is that the system is more stable and reliable. But with the development of wireless technology, it will become the mainstream control technology in the future. It is expected that the market share of Dali will gradually shrink in the future, while ZigBee and Bluetooth will occupy the main position, among which ZigBee is the most common wireless communication protocol for lamp networking. Due to the long development time and relatively mature technology, the network architecture of ZigBee has its own advantages, in addition, it is more power saving. Taking the Chinese market as an example, more and more Chinese manufacturers have begun to join ZigBee alliance, and their products have gradually shifted from most of the past overseas export markets to the domestic market.
