The Composition and Working Principle of Solar Crosswalk Signs
2024-10-16
Pedestrian crossings are set up to ensure the safety of pedestrians, but in real life, not all drivers will slow down when passing through crosswalks, which will make pedestrians have certain risks when passing through crosswalks, especially at night or in rainy, snowy, and foggy weather. When there is insufficient light, it is more likely to be dangerous. The purpose of solar powered pedestrian crossing signs is to improve the visibility of pedestrians crossing the street at night or in low-light conditions and remind passing drivers to slow down through flashing lights, which can also greatly improve the safety of pedestrians in high-risk areas.
Components of solar powered flashing crosswalk signs
1. Solar panels: Solar panels are the key components of solar crosswalk signs, responsible for converting solar energy into electrical energy. These panels are usually installed on the top or side of the sign, with dustproof and waterproof functions, and can ensure efficient operation under different climatic conditions so as to fully receive sunlight. The size and power of the panels depend on the specific equipment requirements, usually high-efficiency polycrystalline silicon or monocrystalline silicon materials with high conversion efficiency.
2. Batteries: Batteries are used to store the electricity generated by solar panels for use at night or when there is insufficient light. Batteries have the characteristics of large capacity, small size, and low cost and are an indispensable component of solar traffic sign products at this stage. Use high-capacity, long-life lithium batteries or lead-acid batteries to ensure continuous power supply in rainy weather or at night. The batteries of solar powered pedestrian crossing signs are generally installed in waterproof casings to cope with outdoor bad weather.
3. Controller: The controller is responsible for managing and regulating the power generated by the solar panels, storing it in energy storage devices, and controlling the switching of LED light sources as needed. Some solar powered pedestrian crossing sign systems are equipped with light sensors or radar sensing devices, which can automatically adjust the working status according to the ambient light, such as automatically starting the LED lights in the dark and automatically turning them off during the day to save energy. Some intelligent signs also support remote monitoring and management, and traffic management departments can view the status of the signs and adjust them through the remote system.
4. Traffic sign surface: The solar crosswalk signs surface is the core part of the traffic sign, which is used to display traffic information such as warnings, prohibitions, and instructions. It is usually made of reflective materials and matched with the flashing of LED lights to ensure that it can be clearly seen during the day and night, prompting drivers to pay attention to pedestrians.
5. LED lights: high brightness LED lights emit flashing warning signals to improve the visibility of the sign. LED lights have low power consumption and long service life and usually have adjustable brightness and flashing frequency to ensure visibility in different environments. The LED lights of solar powered crosswalk signs are usually embedded in the sign board and arranged around the edge of the sign to provide a 360-degree visible warning effect.
6. Sign base plate: The sign base plate of the solar powered crosswalk sign is used to support the sign surface, usually made of a combination of metal sheet and acrylic material. In order to increase the weather resistance for outdoor use, the base plate also needs to undergo special protective treatment.
Working principle of solar powered flashing crosswalk signs
1. Solar power supply: During the day, solar panels absorb sunlight, convert solar energy into electrical energy, and store the electrical energy in energy storage devices through controllers. At this time, the LED light-emitting unit may be in a closed state to save electricity. This energy self-sufficient mode enables the sign to continue to operate at night or on cloudy days, relying entirely on solar energy without connecting to the power grid, saving energy and reducing carbon emissions.
2. Automatic photosensitivity and control: Many solar crosswalk signs are equipped with light sensors that can automatically detect the brightness of the surrounding environment. When night falls or the light is insufficient, the controller will automatically detect the electrical energy in the energy storage device and control the LED light-emitting unit to turn on. The bright light emitted by the LED light outlines the pattern of the pedestrian crossing, providing clear traffic instructions for pedestrians and drivers. During the day or when there is sufficient light, the sign will automatically turn off the LED light to save battery power.
As an innovative traffic safety facility, solar powered crosswalk signs are playing an important role in modern urban traffic management, providing pedestrians and drivers with clearer and safer traffic warnings and also ensuring the orderly and safe operation of urban traffic.
