Brief Introduction To Outdoor Solar LED Street Lights

Solar energy is inexhaustible, clean, pollution-free and renewable green energy. The use of solar power generation has unparalleled cleanliness, high safety, relative extensiveness and adequacy of energy, long life and maintenance-free advantages that other conventional energy does not have. Photovoltaic energy is considered to be the 21st century The most important new energy. The solar street light does not need to lay cables, AC power supply, and no electricity bills; it adopts DC power supply and control; it has the advantages of good stability, long life, high luminous efficiency, easy installation and maintenance, high safety performance, energy saving and environmental protection, economical and practical. It can be widely used in urban main and secondary arterial roads, communities, factories, tourist attractions, parking lots and other places. Product components Light pole structure: steel light pole and bracket, surface spray treatment, battery board connection uses special anti-theft stainless steel screws.

Explanation of the working principle of solar street lights: solar street lights during the day are under the control of the intelligent controller, the solar panels absorb solar light and convert it into electrical energy under the control of the intelligent controller during the day. The light source is powered to realize the lighting function. The DC controller can ensure that the battery pack is not damaged due to overcharging or overdischarging, and it also has functions such as light control, time control, temperature compensation, lightning protection, and reverse polarity protection.

1: At present, one of the most important links restricting the application of solar power is the price. The one-time input cost of the entire street lamp is much higher than that of the city's circuit lamp, which has caused the main bottleneck in the application of solar street lamps.

2: The service life of the battery should also be considered in the application of the entire street lamp system. The general battery is guaranteed for three or five years, but the general battery will be dissatisfied after one year or even six months. Some actual charging rates are It may drop to about 50%, which will definitely affect the normal lighting at night during continuous rainy days, so it is particularly important to choose a better battery.

3: Some engineering companies often use LED lights as the lighting of solar street lights, but the quality of LED lights is uneven. LEDs with severe light decay may attenuate 50% of the illuminance in half a year. So be sure to choose LED lights with slower light decay, or use induction lamps, low-pressure sodium lamps, etc.

4: The choice of controller is often a problem that is ignored by engineering companies. The quality of the controller is not uniform.

5: In places far away from the city, you should also pay attention to anti-theft work. Many engineering companies did not carry out effective anti-theft due to negligence in construction, resulting in the theft of batteries, battery panels and other components, which not only affected normal lighting, but also caused unnecessary property loss. In engineering cases, most of the stolen batteries are batteries. Buried in the ground and poured with cement is an effective anti-theft measure. It is best to weld and strengthen the battery box on the light pole.

6: The waterproof of the controller. The controller is usually installed in the lampshade or battery box, and water is generally not allowed to enter. However, in actual engineering cases, the connection wire of the controller terminal is often short-circuited due to rain water flowing into the controller along the connection wire. Therefore, during construction, you should be careful to bend the internal connection wire into a "U" shape and fix it, and the external connection wire can also be fixed to a "U" shape, so that rainwater cannot enter and cause the controller to short-circuit. In addition, the internal and external wires can also be used. Apply waterproof glue to the interface.

7: Among the many practical applications of solar street lights, solar street lights in many places cannot meet the normal lighting needs, especially in rainy days. In addition to the use of poor quality related components, another main reason is to blindly reduce the cost of components , Do not design and configure according to requirements, reduce the use standards of battery panels and batteries, so that street lights cannot provide lighting in rainy days.

The differences between Solar street lights and ordinary street lights.

1. Energy difference Solar street lights use solar energy, while ordinary street lights use electricity.

2, the voltage difference. Solar street lights are generally 12V or 24V systems, and ordinary street lights are 220V systems.

3, the installation difference. The solar street light is an independent system, and there is no need to dig cable trenches, embedded pipelines, and ordinary street lights. The construction of solar street lights is more convenient.

4, the difference in safety. Solar street lights are low-voltage systems and do not cause harm to the human body. Ordinary street lights are high-voltage systems. Improper installation, wiring, or leakage will endanger the health of personnel.

5, the difference of light source. Solar street lights must use LED light sources. Ordinary street lights can use LED light sources or high-pressure sodium lamps.

6, price difference. Solar street lights have more components and higher quality requirements, so the price is relatively high, and the price of ordinary street lights is relatively low.

Solar street lights and ordinary street lights have their own advantages and disadvantages, and they are widely used. The choice depends mainly on actual needs and site conditions.
