Shining Thousand Village: Philips Solar Off-Grid LED Street Light System

According to statistics, there are currently about 750,000 villages in China, but 200,000 of them cannot achieve normal lighting, and these rural areas are mainly concentrated in the western region. Especially in some remote rural areas where power grid construction is backward due to environmental and historical reasons, the status quo of infrastructure determines that the goal of achieving road lighting is still far away. In this regard, Philips Lighting took the lead in proposing a new idea of ​​solar off-grid LED street light system, combining clean energy, off-grid use and energy-efficient lighting to achieve the leap-forward development of rural road construction in the west and narrow the gap between the central and western regions. A clear new direction has been drawn.

Recently, former British Prime Minister Tony Blair, Ms. Wu Changhua, President of Climate Organization Greater China, Mr. Yu Weixiang, Vice Mayor of Guiyang, and Mr. Lin Liangqi, General Manager of Philips Lighting Greater China, came to Xiaoxi Chongzhai, Huaxi District, Guiyang City. The annual review of the “Thousand Villages Program” initiated by the Climate Organization and the One Foundation. After entering the night, the solar off-network led street lights donated by Philips Lighting illuminate the village front of Xiaoxi Chong, the residents in the village go out to visit friends under bright street lights, or sit idle and talk about the construction of a new socialist countryside. A thriving new weather. The solar off-grid LED street light system has won many users and managers' recognition because of its unique ideas, efficient combination of various subsystems, convenient maintenance and simple use. It is reported that the Guiyang Municipal Government has decided to purchase 150 sets of solar off-grid LED street lights for the lighting of Guiyang Wetland Park. During the National Day, the citizens of the park will be able to see its style.

Integrated "clean energy + efficient lighting" system

Rural road lighting is different from urban lighting systems in that it is highly dependent on the construction of infrastructure such as power grids. Secondly, because the load level of the power grid is lower than that of cities, the problem of power and energy conservation is more prominent. The current basic situation is that rural areas are different from urban centralized energy supply, and energy use is relatively scattered. Facilities such as grids installed in the wild environment are not only costly, but also more likely to waste resources. Therefore, to solve the problem of rural road lighting, it is necessary to consider the factors such as the supply and use efficiency of electricity, and design the lighting system from the perspective of source and use.

From another perspective, rural ecological protection, which is represented by the promotion of energy-saving lighting, is gradually being put on the agenda. It is reported that for the current situation of rural lighting, the Ministry of Construction has launched research and has formed a preliminary "village green lighting plan" program. Fundamentally speaking, increasing the utilization of clean energy can not only solve the problem of electricity use in rural areas, but also make effective use of resources, reduce carbon emissions, and achieve truly sustainable development in rural areas.

The solar off-grid LED road lighting system led by this concept is open both in technology and in application. The first is the solar energy conversion system, which includes solar cells and power storage equipment. This system can also be combined with wind energy use to expand the range of sources of clean energy. It is worth mentioning that its intelligent control system contains a large number of cutting-edge technologies that can optimize battery life according to the climate and seasonal changes of the location, achieve efficiency and performance improvement, and obtain the best output of energy. Secondly, because it does not need to rely on the support of local power grids, it constitutes a complete process of energy supply and use, not only in rural areas where the power grid is weak, but even in cities, the system can be illuminated in green energy roads, pedestrian path lighting, Garden lighting, poster frame lighting and other fields have a wide range of uses. In addition, the system can also play the role of “burdening” the power network during peak hours such as summer.

The significance of the promotion of this system in rural areas is that the lights are illuminated in places where the original grid is not covered, which can strengthen night walks in rural areas and the safety of drivers; extend the time of activities in rural areas and expand the area of ​​activities; Inter-regional exchanges are more frequent and bring more business opportunities. At the same time, this program is sustainable. First, it makes full use of solar energy, which is a renewable energy source, which reduces carbon dioxide emissions from power generation such as firepower, reduces diseases caused by air pollution and mitigates the effects of climate change. Secondly, because there is no cost of wiring construction, such as wiring and digging, the overall installation cost is also reduced, and the maintenance cost will be significantly reduced. This is also very beneficial for improving the efficiency of capital use in new rural construction.

"meaningful innovation" and the new model of Chinese rural lighting

The “Thousand Villages Program” jointly sponsored by the Climate Organization and the One Foundation has promoted the application of solar LED lighting technology in rural areas. After one year of implementation in China, it has achieved remarkable achievements: it has settled in rural areas of Chongqing, Chengdu and Guiyang. There are 40 administrative villages in the region, and the company has donated more than 400 sets of solar LED street lamps to the village government, which has benefited more than 40,000 villagers. As one of the partners, Philips also donated a product worth 1 million yuan in the Thousand Villages Program. In these collaborations, Philips not only developed sophisticated road lighting solutions around solar-powered lighting, but also provided a new paradigm for the future development of rural lighting in China and Asia.

In recent years, Philips has been a diversified multinational company that promotes “healthy, comfortable, quality life” and is committed to improving people's quality of life by introducing meaningful innovations in a timely manner. Among them, “people-oriented” advocates listening to and observing people's voices to ensure that products can truly meet the needs of users. At the same time, “innovative partners” require a new perspective on cooperation to re-examine the relationships among the parties. Win the goal to protect the full range of benefits.

Meaningful innovation means that advanced technology must meet the local specific use environment and user needs. In the design process of Philips off-grid solar LED street light system, the researchers are working in reliability, long-term stability and low maintenance, light weight for various environments, and light intensity, distribution, uniformity, color temperature, color The rendering and the local time required for the actual lighting needs are all considered, so each solution is unique. For example, for the short-term average lighting time in Guizhou, the designers set many conditions under the “worst case”: for example, the longest night in winter, the maximum load of the system; the shortest day, the smallest The sun's light time; the coldest temperature, that is, the minimum usable capacity of the battery, etc., and in these extreme environments, the system should be able to maintain a stable working state, and can adjust the tilt of the solar panel by using an intelligent control system. The angle and the working state of the light source balance the target. The off-grid LED street light system donated to the “Thousand Villages Program”, Philips specially considered the rainy climate characteristics of Guiyang, and the products can meet the lighting needs of six consecutive rainy days.

Philips' world-leading LED technology also provides solid product support for solar off-grid LED lighting systems. The system's Fortimo 1800lm LED road lighting fixtures are not only suitable for walking roads, but also for bicycle lanes and road lighting in industrial areas. It not only has outstanding optical performance, but also has excellent water resistance and easy maintenance. Thanks to its programmable system, the user can easily set the energy-saving dimming conversion of the system for 6, 8, or 10 hours. The appearance of its batwing distribution also reduces light pollution and protects the more precious "night sky" in rural society.

In this regard, Mr. Lin Liangqi, General Manager of Philips Lighting Greater China, said: “We believe in the potential of lighting. The development of lighting technology is to create unlimited possibilities for people's night life. Both rural and urban areas have equal power to share lighting technology development. The result. We are working hard to integrate this scientific advancement into people's lives."

On the road map of urbanization and urbanization in China, modern road lighting systems are indispensable. In the process of building a new socialist countryside, it is equally important to embody the leaps and bounds of development, the harmonious coexistence of people and living communities, and the natural environment. Philips Solar Off-Grid LED Street Light System is undoubtedly a reasonable basis and support for the natural association of “Thousand Villages” and modern “Peach Blossoms”.
