In the face of the rapid development of the rail transit infrastructure market in recent years (in addition to the subway industry, including railways, trams, magnetic levitation and other urban transportation hubs), their huge predictable prospects are tantamount to giving the majority of LED lighting Manufacturers bring opportunities for development. So, how big will this market be?
"New Cake" to be eaten
“With the introduction of the “Technical Specifications for LED Lamps for Lighting in Metro Placesâ€, the standardization system for rail lighting LED lighting will be improved, and the relevant supporting policy environment of the country will also be positive. LED business opportunities are compared with traditional lighting fixtures. LED has the advantages of high energy saving, green environmental protection, strong earthquake resistance and strong stability in rail transit applications. Because rail transit has high stability factor and high seismic resistance and high energy consumption, the LED is very suitable for orbit. Traffic field." Wu Feng, general manager of Spike Optoelectronics, told Gaogong LED.
Before that, let us look at a set of upcoming data: (in Guangdong Province)
1) Guangzhou Track: Guangzhou will consist of 20 urban track lines and 11 Pearl River Delta intercity rail lines. The total length of the network will be 1,164 kilometers. On the basis of the 2010 network, the 2020 line will increase the east line of Line 3.

2) Shenzhen Track: By 2030, it is estimated that 16 lines will be built with a total length of 585.3 kilometers. By 2040, Guangzhou's rail transit will consist of 20 urban track lines and 11 Pearl River Delta intercity rail lines. 1164Km, of which the city line is 811Km, and the intercity line (Guangzhou section) is about 350Km;
3) Other cities: Foshan orbit to 2030, planning 8 lines, totaling 318.712 km/Dongguan track will consist of 4 lines and an intercity suburban railway (Guangshen Suburban Railway) with a total length of 264.2 km/Huizhou Orbital Planning 6 lines, total length 247.5 km / Zhuhai track to 2050, will build 9 rail transit lines, including 6 intercity rail lines and 3 urban rail lines, the entire rail transit network will reach 233.8 km / Zhongshan track It is planned to build six urban orbits by 2050 with a total length of about 153.08 kilometers;
In addition, major high-speed rail projects in the Pearl River Delta: Inter-Shenzhen Intercontinental Orbit, Shenzhen-Hong Kong East Passage, Hong Kong-Zhuhai-Macao Bridge, Guangzhou-Zhuhai Intercity, Guangwan-Shenzhen Intercity, Guangfozhu Intercity, Guangshenyu Intercity, Guangfo Huanhuan, Foshan, Dongguang, Guanghui Intercity (Guangzhou-Qingyuan, Zhongshan-Humen, Dongguan-Huizhou, Zhaoqing-Nansha, Shenzhen-Huizhou, Zhuhai-Shenzhen, Jiangmen-Enping, Zhuhai-Doosan, Humen-Yantian, Shenzhen-Maoming Line), inter-provincial railway connection: Guangzhou-Shenzhen-Hong Kong Passenger Dedicated Line, Xiamen-Shenzhen Railway, Guizhou-Guangzhou Railway, Nanguang Railway, Wuhan-Guangzhou High-speed Railway, coastal high-speed and other projects will also be given to the LED lighting industry in Guangdong Province. External inline brings great opportunities for development.
The above list may be only a part of it. In fact, the project is far from this, as well as railways, trams, magnetic levitation and so on. At present, in addition to ten cities such as Shenzhen, Guangzhou and Beijing, which operate rail transit, more than 40 cities are under construction or planning to build urban rail transit facilities such as subways and light rails.
"LED lighting has great potential for application in urban rail transit and has broad development prospects. It is a new blue ocean for LED market segments. As an important window for urban image display, rail transit is also the best image promotion and brand influence of LED manufacturers. Excellent platform." According to a spokesperson for Wanrun Technology.
In fact, since the beginning of this year, many LED companies including Spike Optoelectronics, Wanrun Technology, and Shanghai Sansi have also put rail transit lighting on the company agenda, and Spike Optoelectronics has won the bid for Shenzhen Metro Phase III Project 7 Line LED comprehensive energy-saving lighting project, and Shenzhen Metro reached a comprehensive strategic partnership, Wanrun Technology also signed a "Strategic Cooperation Agreement" with Changchun Railway Passenger Equipment Co., Ltd. (referred to as "long passenger equipment") in Changchun City.
LED "expansion" is an urgent task
"At the end of this year, the total mileage of railway operations in the country will reach 120,000 kilometers, and it is estimated that by 2020, 177 rail transit lines will be built in China, and the total length will reach 6,100 kilometers." Gaogong Research Institute LED Research Institute (GGII) Senior Analyst Li Shengfa said.
According to GGII survey data, by the end of 2014, the length of urban rail transit lines in 22 cities nationwide was 3,173 kilometers, of which 2,365 kilometers were subways, accounting for 75%; light rails were 239 kilometers, 8%; single tracks were 89 kilometers, occupying 3 %; modern trams 141 km, occupying 4%; maglev traffic 30 km, 1% share; city fast track 308 km, accounting for 10%, China is potential to become the world's largest and fastest growing rail transit construction market .

Rapid expansion of track lighting new blue sea
"The current types of lighting used in urban rail transit construction include fluorescent lamps, metal halide lamps and high-pressure sodium lamps. The lamps have a wide variety of lamps and power, which is not convenient for procurement and maintenance, and cannot be energy-saving and environmentally friendly." Seniors in the lighting industry revealed to Gaogong LED.
It is reported that such traditional lighting fixtures generally have the following problems: First, there are many bare light sources, and glare is harmful; second, the illumination is low, there is a difference between the stations, and the illumination uniformity is not enough; third, the effective luminous flux of the lamps The proportion is small; fourthly, most of the lighting fixtures used are non-efficient energy-saving products, which consume a lot of energy and have extremely high operating costs.
“As the hub of the city, rail transit consumes about 13% of the total electricity consumption of the rail system. At present, the average energy consumption of rail lighting in China is 26W/m2, which is much higher than the national standard (lighting standard 200lx, The energy consumption value is controlled below 6W/m2.) The veteran said that the energy consumption of rail transit lighting is becoming more and more prominent, and the requirements for lighting and power saving are getting higher and higher. Therefore, the comprehensive transformation of LED lighting engineering cannot be delayed.
“Before 2009, the development of the rail transit market was in the market's “quiet periodâ€, and its mileage growth was slow. The entire equipment supply market showed a state of “not stunnedâ€, but in recent years, the decentralization of administrative examination and approval and the opening of private investment Under the release of the approval of the new construction planning line, the domestic urban rail transit will present a new round of infrastructure construction in the next stage.†Li Shengfa mentioned.
GGII expects that by the end of 2020, the total length of urban rail transit planning in China will exceed 6,000 kilometers (excluding railcars and city rails). After deducting the operating lines that have been opened, the average annual operating mileage will be around 900 kilometers. The number of cities with traffic will reach 40 or so, and the amount of investment in rail transit will reach 3-4 trillion yuan.
“In short, from the perspective of the industrial chain, the urban rail transit infrastructure industry is booming, and the design and application of rail transit lighting products will be very effective. From the perspective of the growth rate of rail transit lines and stations, the relevant market demand in the future. The growth will also be a geometric growth, the distribution of lighting applications for various projects, including tunnel lights, street lights, downlights, spotlights, etc., companies in related fields will have much to offer." The veteran finally mentioned.
