2017-2020 LED intelligent lighting market development and reform trend of communication technology

After several years of low price competition and industry consolidation, LED lighting industry has entered a mature stage. The product price increases, market penetration rate increased, the traditional market gradually saturated. The advantage of the enterprise competitiveness is the scale of the enterprise and the product cost gradually shifted to the product and the technical ability, the added value of products is becoming more and more important role.

The rise of the Internet of things, high value of digital lighting LED lighting led to small networking. The intelligent system can collect user, environment and other information through a variety of sensors, and the data were analyzed, then the equipment adjustment. Integration of personalized, people-oriented smart lighting is becoming the focus of future industrial development.

In 2017, with the development of technology, product maturity, actively promote the popularity of the concept of smart lighting manufacturers, related, global smart lighting market has entered a rapid development stage, the market size of nearly $4 billion 600 million, the annual growth rate of 95%. The next few years is expected to market will continue to grow, to 2020 global smart lighting scale up to $13 billion 400 million.

Smart lighting as the wisdom of the city access port with the inherent advantages, the major manufacturers active layout

Smart lighting can not only obtain higher profit margins, but also the wisdom of the city's excellent access point. With the continuous development of the city, to bring the energy consumption and infrastructure construction more and more challenges, is expected to 2030, global city population proportion will reach 60%, city consumption accounts for about 75% of the world's total energy consumption, which accounted for nearly 40% of the total energy consumption of city lighting. As an important part of the smart city, smart lighting in the IOT number of access points have inherent advantages, governments also actively advocated in the construction and development of smart city.

The lighting giants including PHILPS, OSRAM and so on, also have the layout of the market in 2015, PHILPS lighting in the wisdom of the Internet for road lighting pilot project in Losangeles, the deployment of PHILPS CityTouch intelligent road lighting management system in Losangeles in 2017, PHILPS lighting will City Touch flex intelligent road lighting system into China, and networking with the China Telecom for a new generation of things (NB-IoT) technology and Tianyi cloud services combined, including access to city emergency system, traffic management system, security monitoring system, a variety of smart city applications, to accelerate the construction of smart city Chinese.

In January 2018, OSRAM released a new smart city central management platform SymphoCityTM (a set of software and hardware in an open platform system). In addition to the management of lighting, but also to achieve the integration of multiple functions of intelligent city central management platform for comprehensive management of city security, environment, energy and communications. This will help city managers to improve efficiency, reduce costs, and promote the development of smart city.

In addition, Chinese manufacturers, Feile audio Chau Ming technology also vigorously promote the wisdom of lights, is currently undertaking a major Chinese government related projects, Feile audio now with more than 20 city smart city signed a strategic cooperation agreement, and plans to build a total investment volume of about 4 billion yuan of "intelligent cengong" project with the government in cengong County of Guizhou province.

Communication technology continues to change, the development trend of diversification

Networking and smart lighting market development to the current stage, the emergence of DALI, ZigBee, Bluetooth, Wi-Fi, LoRa, NB-IoT, Sigfox, Z-wave, EnOcean and other kinds of communication technology.

In the field of indoor lighting, although there are many wireless communication protocols can be used, but the DALI cable technology for lamp set still occupy the highest market share. The system sets up based on DALI protocol with distributed intelligent modules, each module has a digital control and digital communication, address and lighting scene information are stored in the memory module DALI. The DALI module of digital communication, element transfer instructions and status information through the DALI bus, switch, to achieve light dimming control, system settings and other functions.

The system more stable and reliable is the biggest advantage of cable control technology at present, but with the development of wireless technology matures, will become the mainstream control technology in the future. DALI is expected in the future market share will gradually shrink, while ZigBee and Bluetooth will occupy the main position, where ZigBee is the wireless communication protocol is the most common lighting network. Due to the development of a long time, a relatively mature technology, ZigBee network architecture has more advantages, in addition to saving. In the Chinese market as an example, more and more China manufacturers are beginning to join the Zigbee alliance, the product from the past most of the overseas export market is gradually turning to the domestic market.

Outdoor lighting, ZigBee at this stage is the most widely used. However, due to the application of the short distance, there are many limitations in the application of outdoor lighting, is expected after 2017, the market share of ZigBee in the application of outdoor intelligent lighting will slow down.

With the rise of the Internet of things, many designed for low-power wide area network low bandwidth, low power consumption, long distance, large number of connected networking applications and design (LPWAN) came into being. The spectrum NB-IoT and the non authorized spectrum of LoRa (Long Range) and Sigfox as the mainstream. Long distance communication ability of LPWAN can support large-scale networking deployment, and avoid frequent battery change, reduce maintenance costs.

In low power wide area network in several commercial LoRa earlier and more open, industrial alliance was established in 2015, is currently the most widely used in LPWAN. In 2016 to achieve the standard of frozen NB-IoT, due to the use of licensed spectrum, which can avoid the interference, and with safety and quality assurance level operators, therefore more competitive advantage in the smart lighting scene higher requirements on reliability, the fastest growing market share.

Overall, the current low power wide area network market of more dispersed, the market share is still low. Expected with the technology development and perfect function, market concentration will gradually improve. (details refer to LEDinside Silver members - the global lighting market trends report).
