Safety is the cornerstone of human society's survival and development. In the road and public area environment, the importance of safety is even more self-evident. Safe road lighting conditions are the key to reducing traffic accidents and ensuring smooth travelling for residents at night. It enables drivers to clearly identify road conditions at night, avoid dangers in time, reduce the incidence of accidents and protect people's lives and property. At the same time, a good regional security environment is conducive to the normal development of commercial activities at night, to promote economic prosperity. For example, the city's commercial streets, bright and safe environment will attract more consumers shopping and leisure at night, driving the night economic growth.
In the development process of modern lighting facilities, solar street lamps have gradually become the core force of security by virtue of its unique advantages. With clean solar energy as energy source, it not only conforms to the concept of environmental protection, but also provides reliable security for all kinds of scenarios in terms of lighting function. Next, let us delve into the close links between solar street lights and security, to see how it protects our lives.
The working principle of solar street lights enables them to provide continuous and stable lighting at night or in low-light environments. During the day, the solar panel acts as an efficient energy collector, absorbing sunlight to its fullest. The semiconductor material inside generates electron-cavity pairs under the impact of photons, creating an electric current that converts solar energy into electricity. The electricity is then converted into electrical energy, which is stored in the battery under the precise control of the charge controller. When night falls and the surrounding light fades to a certain level, the light sensor quickly senses and automatically switches on the circuit, and the electricity in the battery drives the LEDs to glow, instantly lighting up the darkness.
Traditional streetlights rely on the power grid to supply electricity, and once a power outage occurs, such as a power equipment failure or severe weather damage to the power supply line, the lighting will be interrupted, and the darkness will instantly envelop the area, greatly increasing the safety risk. Solar streetlights are independent of the power grid, and their self-contained power supply system makes them unaffected by power grid failures, and they always hold their positions and continue to emit light, ensuring the continuity of lighting and effectively reducing potential safety hazards such as falls of pedestrians and collisions of vehicles due to the lack of lighting.
The design of the solar street light takes into full consideration the needs of different application scenarios, and is able to flexibly adjust the lighting angle and range. On the road, the height and angle of the street light are carefully calculated so that the light evenly covers the road surface, whether it is a wide main road or a narrow alley, it can achieve dead-angle-free lighting. In car parks, the light focuses on the parking spaces and passages, so that car owners can clearly see the surrounding vehicles and pedestrians and facilitate parking. In small areas, solar street lights illuminate roads, green belts and leisure areas, leaving no dark corners for potentially dangerous areas.
LED lamps, as the light source of solar street lights, have many advantages. Among them, high colour rendering is particularly prominent. High colour rendering means that LED lamps are highly capable of reproducing the true colours and details of objects. Under its illumination, drivers can clearly distinguish whether the traffic markings on the road are solid or dotted lines, and accurately determine whether they can change lanes; pedestrians can see the roadside signs, and clearly understand their own position and direction of travel. This clear visual effect, greatly enhancing the safety of people on the road and public areas when the activities.
Under good lighting conditions, drivers' vision is greatly expanded. They can clearly observe the driving status of the vehicle in front of them in advance, judge the distance between the vehicles, and make timely decisions to accelerate, decelerate or avoid. For curves, they can prejudge the turning radius and control the speed in advance; facing intersections, they can clearly see traffic signals and cars coming from other directions. Relevant research data show that after installing solar street lights on major roads in a city, the incidence of traffic accidents at night was reduced by 80%. This fully demonstrates the significant role of adequate lighting in reducing traffic accidents.
Solar street lights can also strengthen road markings. Traffic markings and signs are more visible under the bright light. Drivers can see the speed limit signs, no-passing signs, etc. from a distance, so as to consciously abide by the traffic rules and reduce the illegal driving behaviours caused by unclear markings, such as speeding, running red lights, changing lanes at will, etc., which are often important factors triggering traffic accidents.
Well-lit streets allow pedestrians to walk with more confidence. They can clearly see the road conditions and avoid potholes, bumps and other obstacles in time.
potholes, bumps and other obstacles, avoiding falls and injuries due to poor visibility. Good lighting is especially important for the elderly, children and people with limited mobility. At pedestrian crossings, the lighting of solar street lamps enables drivers to notice pedestrians crossing the road in time, and take the initiative to stop and give way to ensure that pedestrians have the right of way. In the bus station, bright lights so that passengers feel at ease waiting for the bus, but also to facilitate the driver accurately stopping the station, reduce the conflict between people and vehicles, to protect the safety of both sides.
Lighting has a strong deterrent effect on criminal behaviour. Darkness is often the ‘cover coat’ of the lawless elements, they are more likely to hide their whereabouts in the darkness, the implementation of theft, assault and other crimes. And the bright environment created by solar streetlights makes crimes invisible. In the community, street lights illuminate every corner, residents can clearly see the surrounding situation, and any abnormalities can be detected and reported to the police in a timely manner. In parks, the crowd exercising and walking at night moves under the light, and the wrongdoers dare not approach easily. From the psychological level, the bright environment so that lawbreakers are afraid to commit crimes easily; from the actual monitoring level, the light is sufficient to facilitate the surveillance cameras to capture the picture, providing strong clues for police investigations, greatly reducing the likelihood of a crime occurring.
In the event of natural disasters or emergencies, the importance of solar street lights is more prominent. For example, after an earthquake, the city infrastructure may be severely damaged and the power grid paralysed, but the solar street lights can still illuminate normally, guiding the way for the rescuers to arrive at the affected area quickly to carry out rescue work. In the fire scene, bright street lights help fire vehicles to accurately find the location of the fire source and improve the efficiency of fire extinguishing. For the affected people, solar street lights can be used as emergency signs, in the chaotic environment, they can follow the direction of the street lights to find safe evacuation routes, orderly evacuation, to protect their own safety.
Solar street lights use renewable solar energy as energy source and achieve zero carbon emission during operation. Compared with the traditional street lamps relying on fossil energy to generate electricity, burning coal, oil and other pollutants that produce a lot of carbon dioxide, sulfur dioxide and other pollutants, solar street lamps from the source to reduce air pollution. Good air quality is vital to the health of residents, reducing the incidence of respiratory diseases, cardiovascular diseases and other diseases. In the long run, safeguarding the health of residents also guarantees the safety and stability of life. In addition, the pollution of the environment by traditional street lamp power generation may cause ecological security problems, such as the destruction of buildings and vegetation by acid rain, while solar street lamps effectively avoid these problems and contribute to ecological security.
The components of solar street lights, such as solar panels, batteries, LED lights, etc., have a long service life. High-quality solar panels can be used for more than 25 years, batteries can last for 3 - 5 years or even longer under normal use, and LED lights can last for tens of thousands of hours. This means that solar street lights do not require frequent replacement and maintenance during long-term use, ensuring the continuity of lighting safety and security. In the context of energy transition, the global reliance on traditional fossil energy is gradually decreasing, and energy shortages and price fluctuations have become unstable factors affecting traditional street lighting. The solar street light is not disturbed by these factors, and it always stably provides a safe lighting environment for the society and guarantees the safety of people's activities on roads and in public areas.
Solar street light plays a key role for safety and security in many aspects. It helps traffic safety by providing sufficient and stable lighting, optimising the range and quality of lighting, reducing traffic accidents and ensuring pedestrian safety. In public areas, it deters criminal behaviour and enhances emergency safety. At the same time, its environmentally friendly nature brings long-term safety benefits and sustainability ensures stable and safe lighting.
Road builders, city managers, community properties and other relevant parties should fully recognise the importance and irreplaceability of solar streetlights in the field of safety and security. Actively choose solar street lights and increase the installation and application in all kinds of roads and public areas. Let solar street lights illuminate every corner, contribute to building a safe, green and sustainable living environment, and let people enjoy a better life in light and safety.
