The attractive market cake of subway lighting has provoked the mouths of many lighting manufacturers. Whether it is Philips, Sanxiong, Aurora and other old-fashioned lighting companies, LED companies such as Xinli Light Source, Shifu Lighting, and Shengpu Optoelectronics are competing to seize the subway lighting market.
However, due to the need to ensure the safe operation of the subway, the subway room has very high requirements for lighting fixtures. It requires not only power saving, high brightness, long life, but also uninterrupted lighting.
The market has opened up
In 2008, the Hong Kong MTR and Jiuzhou Optoelectronics introduced LED light source as the first interior lighting of subway cars in the world, which opened the LED era of subway lighting.
In 2011, the relevant state departments issued the "Technical Specifications for LED Lighting for Metro Places", which detailed the procurement specifications for subway LED lighting, and opened the standardization path for subway LED lighting.
“Considering the diverse needs of metro lighting, LED is undoubtedly the best choice for metro lighting. It has the unparalleled advantages of traditional lighting in terms of energy saving, stability and durability, and the strong shock resistance of LED is very suitable for subway operation. Environment.†A hydropower management engineer in charge of the Shenzhen Metro Line 2 told the reporter.
"In view of the problems existing in the current subway lighting system, LED provides a subway lighting solution with novel structure, long service life, good power saving effect and high reliability." The person in charge said.
It is understood that the Shenzhen Metro Line 2 is about 33 kilometers in length, all of which are underground lines, with a total of 29 stations, of which 9 are transfer stations, and the number of LED lamps purchased is about 25,500 sets.
The project was built by Shanghai Sansi Technology Development Co., Ltd. The entire lighting system uses dimming control to facilitate different brightness during different working hours to achieve better energy saving and longer life.
According to a survey by the reporter, there are currently about 48 domestic subways, and 28 cities are building subways. In the existing domestic subway network, taking the Shenzhen Metro as an example, in addition to the use of LED lighting in the entire line of Line 2, the rest of the use of traditional lighting, the LED market potential of subway lighting can be described as quite large.
In addition, Guangzhou Metro Line 2 Sanyuanli, Railway Station, Yuexiu Park, Memorial Hall, Park Front, Haizhu Square, City Ergong, Jiangnan West, Zhongda, Lujiang, Kecun, Moshasha, Xingangdong, Weizhou A total of 14 stations in the public area lighting system and other fields, will begin to replace energy-saving LED lamps this year, the number of modified lamps is about 18,000 sets.
Coincidentally, RATP, a Paris-based public transport organization in France, has also signed a four-year contract with Philips and French lighting company Stepand Soitec for the 2,200,000 subway stations of the Paris Express Railway network and 66 suburban subway stations. The lamp is retrofitted with LEDs.
Benjamin Azoulay, general manager of Philips Lighting France, said that this cooperation will make Paris the world's first transportation network fully equipped with LED lighting.
EMC "unacceptable"
However, unlike the large-scale commercial promotion model in Europe and the United States, LED lighting in mainland China is also a tentative project led by the government. The commercialization idea is still unclear, which has caused great impact on the commercialization of domestic LED engineering. Troubled.
The EMC energy contract management model has played an important role in large-scale LED projects such as subway lighting in foreign countries.
Through the new cooperation mechanism of EMC, the MTRC does not have to bear the project cost in the early stage of the project, and cooperates with the LED enterprise with “zero cost†investment, while the LED enterprise recovers the investment and obtains the energy saving benefits obtained during the project implementation process. profit.
As an "imported product", the EMC model has suffered from "water and soil discomfort" in China, and the market promotion situation is difficult to open. An industry insider told reporters: "The reason why the EMC model is difficult to promote in China, in addition to the domestic understanding of it, there are still many institutional obstacles."
Enterprises and users have low mutual trust. LED companies will have financial risks when implementing EMC projects. It is not certain whether the owners can perform credit performance and pay energy savings on time after receiving energy-saving benefits. The owners who accept the implementation of lighting renovation are not sure whether the technology and products provided by LED companies and the service capabilities of the company are excellent.
EMC projects have problems with financing difficulties. In the early stage of EMC project implementation, LED companies need to provide a large amount of start-up funds in advance, and the bank's loan requirements for this business cooperation model are not recognized, resulting in difficulties in financing LED companies.
The state has over-taxed the EMC model. Since the state has not introduced a taxation specification specifically for the EMC model, the energy-saving income obtained by the LED enterprise is regarded as the markup of the general energy-saving equipment seller, and the VAT is included in the regulation, resulting in excessive taxation.
The above three obstacles have cast a shadow over the commercialization process of domestic LED lighting.
Intelligence is not "smart"
In the era of LED application, the attributes of lamps are no longer scattered individuals, but a collection of LED lamps into a single lighting system, and then an intelligent management platform to achieve a variety of control modes.
Honorary Director of the Indoor Lighting Professional Committee of the China Illuminating Society, Ren Yuanhui, deputy director of the National Lighting and Lighting Standards Technical Committee believes that the LED application of the intelligent control system to the architectural staircase and aisle lighting will fully utilize the energy-saving advantages of LEDs to achieve The concept of “lighting†is used to achieve the dimming effect of “lights coming from people and dark lights†to achieve good energy-saving effects.
“When LED light efficiency reaches the limit of use, the energy-saving effect is no longer the final interest point of LED lighting. In the future, LED lighting competition is more reflected in the intelligent demand.†Dr. Xu Chen, deputy director of Guangdong Standardization Research Institute said, “LEDs determine their future intelligent lighting direction with their light source characteristics.â€
However, the data of the High-tech LED Industry Research Institute (GLII) shows that the penetration rate of domestic LED intelligent lighting is less than 2%.
The domestic LED companies' understanding of the concept of intelligence and the development of technology are not deep enough, and they still stay in the simple stage of dimming and coloring LED lamps.
Of course, this has nothing to do with the current status of domestic LED intelligent technology is not high. Due to the lack of relevant intelligent equipment support, the LED intelligent platform is not perfect, and the operability is not strong.
