As an environmentally friendly, energy -saving lighting solution, solar street lights have been widely used in various public places such as cities, villages, roads, and parking lots in recent years. It can not only reduce energy consumption, but also have the advantages of no need to lay cables and reduce construction difficulty. The efficient operation of solar street lights is inseparable from the precision design and functional collaboration of each structured piece. This article will explore the main structural parts of solar street lights to help readers better understand their working principles and technical requirements.
- Solar Panel
One of the core components of solar street lights is solar panels, also known as photovoltaic boards. It is responsible for transforming solar energy into electrical energy, battery storage or direct drive lamp lighting for street lights. The main technical indicators of solar panels include photoelectric conversion efficiency, wind resistance, weather resistance, etc. Common solar panel types include single crystal silicon and polycrystalline silicon plates. Among them, monocrystalline silicon boards have higher efficiency and longer service life, but the price is higher. What is a solar street light? How do they work?
Features:
Photoelectric conversion efficiency: The higher the efficiency of solar panels, the more electrical energy is transformed, which ensures that the street lights can still work normally under the condition of weak sunlight.
Compression and weather resistance: Because the solar board is exposed to the outdoor environment for a long time, its performance of wind resistance, waterproof, dustproof and other performance is essential.
- Battery
Battery is a key component used in solar street lights to store solar energy into electrical energy. Usually, the battery uses a lithium battery or lead -acid battery. Lithium batteries have become the first choice for modern solar street lights due to its high energy density, long life and lighter weight. The battery needs to have the ability to quickly charge and discharge for a long time, and be able to maintain long -term lighting under bad weather conditions. How much watt is a suitable solar lamp?
Features:
Capacity: The capacity of the battery needs to be selected according to the power requirements of the street lights, the expected lighting time, and the local sunshine.
Life life: The life of batteries is usually one of the important indicators of the overall service life of solar street lights.
- LED Light Source
LED light source is a lighting part of solar street lights. Generally, LED lamp beads with high brightness and low power consumption are selected. Compared with traditional street lights, LED lamps can not only consume low, high brightness, long service life, but also more environmentally friendly. The power and brightness of the LED light source can be adjusted according to actual needs to ensure that sufficient lighting effects are provided under different environments and conditions. Take you to understand the top ten differences between solar street lights and LED street lights.
Features:
Brightness and power: When selecting the LED light source, the power of the light source must be determined according to the installation height and irradiation range of the street lights to ensure that it provides sufficient lighting.
Energy -saving and environmental protection: LED light sources are the most energy -saving part of solar street lights, and can maximize the use of electricity obtained from solar panels.
- Controller (Controller)
The controller of solar street lights is the core of its intelligent management and is responsible for coordinating the work of each component. The controller can not only regulate the switch of the light source, but also monitor the charging and discharge status of the battery to ensure the efficient operation of the system. Modern solar street light controller usually has various functions such as light control, time control, and remote control. It can automatically adjust the brightness of the street light according to the intensity of the environmental light to extend the service life of the battery.
Features:
Intelligence: Advanced controllers can automatically adjust the brightness according to weather changes to ensure the balance between charging and discharge.
Excessive protection and anti -short circuit: The controller has over -charged and placed protection functions to avoid battery damage.
- Lamp Pole
The lamp rod is a supporting structure of solar street lights. It is generally made of steel or aluminum alloy, which has the characteristics of high strength, corrosion resistance, and wind resistance. The height of the light rod is usually designed according to the width and lighting requirements of the road. The common height range is 4 to 10 meters. The design of the light rod must not only ensure the weight of supporting solar panels, LED lamps, and batteries, but also need to consider external forces such as windloads and earthquake resistance.
Features:
Material: Steel lamp rods are common on urban roads, while aluminum alloy materials are more light, suitable for small communities and rural roads.
Anti -corrosion: The light rod is usually processed to increase its service life under severe weather conditions.
- Bracket
The bracket is an important part used to fix solar panels and lamps. The solar board needs to be connected to the light rod through the bracket, while maintaining a certain angle at the same time to maximize the receiving sunlight. The design of the bracket should conform to the principles of mechanics to ensure that in different environments (such as strong wind and high temperature), components can be firmly fixed.
Features:
Adjustment angle: The bracket is generally designed as a structure with adjustable angles so that the angle of solar panels can be adjusted according to different geographical locations to ensure efficient charging.
Wind resistance: The bracket requires sufficient strength and stability to cope with the wind in the harsh climate environment.
- Sensor (Sensor)
In order to achieve more intelligent functions, modern solar street lights are often equipped with sensors. Common sensors include light sensors and motion sensors. The light sensor is used to monitor the strength of the light and automatically control the switch of the street light. The motion sensor is used to detect the surrounding dynamics. When someone passes, the system will automatically increase the brightness to provide better lighting effects.
Features:
Energy -saving: The light sensor can automatically switch the street lights according to the changes in environmental light, saving unnecessary energy consumption.
Intelligence: The application of sports sensors can increase the safety of the night and avoid unnecessary power consumption.
- WaterProof Housing
Each electrical component of solar street lights requires a solid shell to prevent moisture invasion and corrosion. Especially the battery, controller and LED light source need to use waterproof housing. The common waterproof standard is IP65 or higher, which means that it can resist strong water flow and dust.
Features:
Waterproofing: The shell needs to have excellent sealing to ensure that the equipment can still run normally in rainwater and humid environment.
Duravity: Waterproof housing is generally made of high -strength plastic or aluminum alloy, which has the characteristics of anti -aging and corrosion resistance.
Conclusion
Solar street lights have become an important part of modern urban lighting through efficient component collaboration. From solar panels to LED light sources, from battery to the controller, each structural part has its unique function and technical requirements. With the continuous advancement of technology, the components of solar street lights are gradually optimizing to improve the effectiveness, durability and intelligence level of the overall system.
