About the impact of lightning on solar garden lights and preventive measures

The price of each garden lamp is different. In addition, some poles require embossing or other special shapes. The base of solar garden lights is usually die-cast aluminum. There are also some main products made of copper or alloys on the market. Aluminum and other materials are usually expensive to make by hand. The transparent part is made of acrylic or printed board. These materials have the characteristics of good light transmittance, anti-oxidation UV, not easy to yellow, and long service life.

u003cbru003e The solar garden light pole is made of aluminum or steel, and the outside is galvanized and sprayed with anti-corrosion and anti-rust treatment. Usually, fluorocarbon paint is applied to the surface to add anti-ultraviolet powder to improve the corrosion resistance and oxidation resistance of the electrode. The appearance color of the light pole can be made according to the relevant requirements of the customer, or it can be produced by the customer.

u003cbru003e Solar garden lights are installed outdoors. When it rains, lightning is inevitable, so lightning strikes become a great threat. The light can damage the solar garden lights, and the heavy light can cause fire or casualties, causing huge losses. The following garden light manufacturers will introduce the impact of lightning on solar garden lights and preventive measures:

u003cbru003e At present, the outer part of general solar garden lights is made of conductive material, which is equivalent to the lightning rod itself. In the design, down conductor and grounding network must be installed. These systems constitute an external lightning protection system. The system can avoid fire and personal safety accidents caused by the direct lightning strike of the solar garden lamp. The internal lightning protection system refers to the protection of the equipment inside the solar garden light through grounding and voltage protection. The system can prevent lightning induction and other forms of overvoltage intrusion, resulting in damage to the power supply, which cannot be guaranteed by external lightning protection systems. The two are complementary. The internal lightning protection system must be connected to the external lightning protection system or overvoltage protector on many devices, such as the enclosure, the cables entering and leaving the protected area, and metal pipes, as well as equipotential bonding.

u003cbru003e Completely eliminate the destructive potential difference caused by lightning. Power lines, signal lines, metal pipes, etc. must be equipotentially connected with overvoltage protectors, and local equipotential connections must also be made at the interface of each internal protection area. The equipotential bonding must be connected to each other and finally to the main equipotential bonding.

u003cbru003e At present, in addition to power supply equipment, solar garden lights will also be equipped with some communication equipment to control the switch and brightness of solar garden lights. These devices and power supplies need to be placed in the lightning protection zone, and the protection zone is directly shielded by the shell. The electromagnetic field here is much weaker.

u003cbru003e The function of lightning protection equipment is to connect the protected system to the equipotential system in a short time, so that each port of the equipment is equipotential. At the same time, the huge pulse energy generated by the lightning strike in the circuit is released to the ground through the short-circuit line, which reduces the potential difference at each interface of the device, thereby protecting the device.
