LED street lights without grounding wires, 8 meters high, will be damaged by lightning?

LED street lights do not have a grounding wire, the height is 8 meters, whether it will be damaged by lightning, this is a question worth **. Lightning strikes are a natural phenomenon that occurs when an electric field difference is formed between the positive charge in the clouds and the negative charge on the ground. The energy of lightning discharges is very huge and can wreak havoc on objects.

First of all, we need to understand how LED street lights work. LED street lights emit light through semiconductor materials, and their operating voltage is generally low-voltage, usually between 12V and 48V. In contrast, the voltage of lightning discharge is very high and can reach millions of volts.

Therefore, from a voltage point of view, the working voltage of LED street lights is much lower than the voltage of lightning discharge, so it will not be directly affected by lightning strikes.

However, lightning discharges generate a powerful electromagnetic field that can interfere with electronic devices. Although LED street lights operate at a low voltage, their electronic components and circuits are still affected by the electromagnetic fields generated by lightning discharge. If the electromagnetic field strength of lightning discharge is large enough, it may cause damage to the electronic components and circuits of LED street lights, causing street lights to not work properly.

In addition, lightning discharges generate an electric current, which is conducted through the ground. If the LED street light does not have a grounding wire, then the current from the lightning discharge may flow into the ground through the metal pole body of the street light. Since the flow of electric current creates a voltage drop, if there is resistance between the metal pole of the street lamp and the ground, then the voltage drop will occur when the current passes through the metal pole body, which may cause damage to the electronic components and circuitry of the street lamp.

To sum up, LED street lights do not have a grounding wire and are 8 meters high, which may be affected by lightning discharge. Although street lights operate at a low voltage and are not directly affected by lightning strikes, the electromagnetic fields and currents generated by lightning discharges can cause damage to the electronic components and circuitry of street lights. Therefore, in order to protect LED street lights from lightning strikes, it is recommended that when installing LED street lights, they should be grounded to provide a low impedance path, so that the current of lightning discharge can flow smoothly to the ground and reduce the damage to the street lights.

Generally, there is no problem, the constant current source is with lightning protection.

The ground wire of the electrical appliance cannot prevent lightning strikes, but it is directly introduced to the ground when the electrical appliance leaks electricity to prevent it from being shocked. Lightning protection is the work of some corresponding circuit breaker equipment connected to the power distribution room and the lightning rod of high-rise buildings.

LED 8 meter street lamps generally need to be grounded, the main thing is the need for equipotential and lightning protection

It has little to do with not being grounded, mainly because the lightning protection facilities of the whole line do not play a role, and the quality of the lightning rod and grounding wire is not up to par, and I am really helping you look forward to adopting

Personally, I think that the power supply of the street lamp is not grounded, the surge filter in the power supply does not have much effect, and the power input surge interference energy cannot be released to the ground. If the aluminum substrate is not well insulated, it will be discharged to the ground through the aluminum substrate, resulting in the dead lamp beads. I have a friend who encountered the problem of LED street lamp beads burning to death, and it was obvious that the instantaneous high current burned out under the microscope.

The cause has not yet been clarified, but it is estimated that the same problem is the same.

Basically, nothing is a problem. The shell of the street lamp is grounded and not afraid of thunder. If there is a grounding end inside, it can also be directly connected to the metal shell of the street lamp, and the metal shell can be grounded. Otherwise, lightning strikes or electricity leaks, and people who like to touch street lamps will suffer

LEDs themselves are very sensitive to lightning surge currents, and the electrostatic touch of the human body may cause damage to them, burning chips or leads. Therefore, the street light circuit must be grounded.

If a lamp head is expensive, it will be sold for tens of thousands of yuan, because if it is not grounded, it may not be worth the loss.

If people can't reach it, it's fine.

LED is low-voltage DC, what kind of ground?

Outdoor lamps are to be grounded.

Although the probability of lightning destroying lamps is very small, grounding is not just for lightning protection, lamps and lanterns are connected to the fire wire, and if the fire wire leaks, it will endanger the safety of life.

Outdoor lamps and lanterns, such as high-mast lights, must be grounded, because they are very high, and they are easy to contact with lightning and are easy to cause impact.

It depends on the actual situation

Look at the installation height;

Look at your surroundings;

No, the light itself is safe, as long as it doesn't touch the line, it's fine.

Unless you are struck by lightning, you won't.

Please follow the operating procedures. Don't be careless.

Hello, there is no problem with a light pole of 10 meters, if it is a medium and high pole, there is a problem, I am an LED street light manufacturer.

Static electricity accumulates, and it is easy to break down the device over time.

This is still not grounded, and the effect is equivalent to covering your ears and stealing the bell. In case of leakage caused by wiring, the leakage protector will not act, but will export the power to the indoor interconnected socket, increasing the risk of electric shock.

LED lamps usually have no grounding requirements, the metal part of the shell and the inner circuit are high-voltage insulation grades (due to the performance of aluminum substrates), and lamps with exposed metal are generally designed to be difficult for people to touch and use at high levels.

The ineffective and artificially increased so-called grounding wire must increase the distribution capacitance of the trace, thereby increasing the leakage current between the lines, which may cause the LED to appear faint and flicker after the light is turned off.

Yes. No problem.

The national standard GB7000 says that the so-called grounding refers to the metal parts that are easy to touch by the lamp, which must be grounded.

As long as the shell of the lamp is grounded, the power supply is in the lamp, and it doesn't matter if it is grounded or not. The grounding protection function has met the requirements of national standards.

Because the power supply has no ground wire, it cannot form a circuit, and it is useless to connect it.
