The characteristics and applications of solar street lights

In the development of urban economy, street lights are an indispensable part. Traditional street lights rely on the power grid for power supply and illumination. If a power outage occurs, the street lights will not be used, which requires high technical standards and is difficult to maintain. Currently, solar power generation is becoming increasingly mature, with a wider range of applications that fully meet the lighting needs of urban street lights. Therefore, major cities have begun to use solar street lights to improve energy structure, enhance service life, and reduce maintenance costs

The functional characteristics of solar street lights

In the urban infrastructure service system, road lighting is an important component that directly affects people’s production and life. With the development of society and economy, the contradiction between humans and the natural environment is worsening day by day. The concept of sustainable development has been proposed, which has promoted the widespread application of solar power generation technology in various industries. Solar power generation has the characteristics of green and environmental protection, and has received attention from infrastructure construction in major cities. In the application process, there are advantages that traditional street lights do not have. There is no need to install cables or arrange dedicated personnel for management, making it easy to install in areas that require lighting in the city. Compared with traditional lighting methods, it has advantages such as high brightness, small light source volume, light weight, strong adaptability, and long usage cycle, which other lighting tools cannot have. Within the same lighting time, it has low energy consumption, simple installation, and convenient maintenance.

Solar street lights are generally composed of battery panels, batteries, lighting fixtures, controllers, etc. The number of components required for operation is small, and there is basically no noise generated. The controller mainly regulates the circuit and plays a similar role as traditional street lights, achieving the operation of turning off the lights during the day and turning them on at night. The difference is that the battery needs to be managed. At present, there are three types of controls used in solar street lights, and although their working methods and advantages and disadvantages are different, they all utilize solar power generation.

Solar street lights using a separate light controller. Mainly using the photosensitive principle, if the light weakens, it will automatically turn on the street lights; When the light is strong, the street lights will be turned off. The early use of optical control circuits was complex and prone to malfunctions; After the development of semiconductor technology, integrated circuits were formed, which simplified their circuits and gradually became a key component of solar street lights. Secondly, solar street lights using clock controllers. This design principle avoids the light factor by setting the time for the street lights to automatically turn off and on, thereby enabling the street lights to illuminate on time and achieving the goal of energy conservation. The advantage of this mode is that it is not limited by external factors. If the street light itself malfunctions, it will only cause incorrect operation; The disadvantage is that it cannot automatically adjust the time based on seasonal characteristics and requires manual adjustment. This type of solar street light is widely used, especially after the implementation of IoT technology, the time adjustment can be adjusted through the system, and different adjustments can be made one by one. Thirdly, solar street lights using latitude and longitude controllers. This design principle utilizes microcontroller technology to simulate sunlight conditions at different latitudes and longitudes, enabling the street lights to be turned on after dark and turned off after dawn. This mode fully utilizes the advantages of light control, avoids the influence of external factors on street lights, and also draws on the principle of time control. It can turn on or off street lights in the corresponding environment, but the cost of a single street light is very high.

Measures to enhance the application of solar street lights

Choose a suitable light source

Solar street light sources are different from traditional streetlights, which requires the selection of appropriate light sources in the design process of streetlights to ensure that they can exert their lighting functions. In general, the power of the light source used in solar street lamps should be three times that of traditional street lamps. If the traditional lighting source is 50W, the solar street lamp should be 150W. Based on the power of the light source, it can be inferred that the size of the solar panel should not be less than 2m ³。 In the process of selecting light sources, it is necessary to consider that the solar power supply mode is low-voltage power supply, which requires full consideration of the external environment. By analyzing the installation location, working hours, climate and environment of street lights, appropriate light sources are selected to better provide lighting for users.

Strictly control the switch

Currently, solar energy can be controlled in three ways, all of which can achieve the function of street lights. However, different control methods have different requirements for switches, and there are also differences in cost and cost. The individual light controller and the latitude and longitude controller can be adjusted manually, and the time to turn on or off the street lights can be automatically adjusted according to the external environment. For these two methods, street light management personnel need to regularly inspect their working systems to ensure that each component is working properly. It is also possible to collect operational data based on sensors on each critical device, achieving dynamic device management. Through data analysis, it is possible to understand the working conditions and service life of different equipment, ensuring timely replacement and maintenance by operation and maintenance personnel. However, the cost of the warp and weft controller is relatively high, and if there is no high cost budget, a separate optical control system can be chosen. Although the clock controller can automatically switch on and off street lights, it cannot adjust the switch time according to seasonal changes and requires manual adjustment, which is easily affected by seasonal factors. If a reasonable switch time cannot be set, it can easily lead to energy waste. Therefore, the use of the Internet of Things should be increased, and through the integration and application of various technologies, the problems of clock controllers should be gradually solved to better ensure their application scope.

Strengthen battery management

The decisive factor in the lifespan of solar street lights is the battery, which can also affect the functionality of other components. If the battery has a large capacity, it will never remain fully charged during use, resulting in a decrease in battery life. After the installation of the battery is completed, it is necessary to strengthen the operation and maintenance management in the later stage, closely monitor the usage of the battery, and once any malfunction is found in its operation, it should be immediately repaired or replaced to ensure the efficient use of solar street lights. Therefore, by strengthening battery management, its functionality can be fully utilized and its service life can be guaranteed.

summary

Solar street lights are widely used in cities, and many controller methods have emerged. Different methods can achieve street light switching. However, in the selection of various components of solar street lights, it is necessary to tailor the application method according to the installation location of the street lights, to better utilize the functions of solar street lights, provide convenience for urban residents’ travel, and achieve energy-saving goals.
