一. The main reason LED street lights don't work is because the power supply or power supply system is broken.
need a very stable power supply because they run on low-voltage DC. If there is anything wrong with the power supply chain, the lights may not work.Some common situations are power outages, old or broken cables, subterranean cables that were damaged during construction, loose or oxidised wiring terminals, and so on. Some LED street lights may have junction boxes that aren't well sealed, which lets rainwater in and causes short circuits or electrical leakage. This sets off the protection device and makes the whole
二. The LED drive power supply is broken, thus the street lamp can't be lit.
If the power supply system is working correctly, the LED driver power supply is the next thing to check. The driver power supply is like the "heart" of the LED street light. Its main job is to change alternating current (AC) into reliable direct current (DC) so that the LED beads get the right amount of current and voltage.
street lights work all the time outside, where it is hot, humid, and lightning hits often. This can cause the internal parts of the driving power supply to wear out. Problems like bulging electrolytic capacitors, broken MOSFETs, and broken rectifier modules can all cause the driving power supply to work incorrectly, which means that the LED street lights won't turn on.
三. The issue of not lighting up is due to problems with the intelligent module or control system.
As smart cities grow, more and more LED street lights come with smart control systems, like light control, time control, remote centralised control, or IoT modules. These If the light-controlled sensor is broken and doesn't accurately measure how bright the environment is, the LED street lights might not turn on at night. If the time-control module's parameter settings are wrong, the lights may also turn on and off at strange times. If the communication module stops working or the backend settings are wrong, all of the LED street lights in a centralised control system may stay off.
四. Less waterproof performance that damages parts inside
Most of the time, LED street lights are put outside, where they are exposed to rain, moisture, and dust for long periods of time. This means that the fixtures need to be very waterproof. If the waterproofing isn't good enough or the seal starts to break down, a lot of problems can happen.
Moisture can get inside the lamp because the sealing glue on the lamp housing is old, the ventilation valve is broken, or the wire port wasn't properly waterproofed. Moisture can damage the circuit board, which can cause short circuits, electrical leaks, or rusting of parts. This can eventually cause the LED street light to stop working.This problem is especially widespread in places with a lot of rain or near the coast, and it often hides itself. At first, it doesn't work sometimes, and then it stops working totally.
五.Hidden problems caused by improper installation and construction
Some LED street lights don't work because of problems with the installation and construction process, not because of problems with the product itself. For example, wires that are crimped incorrectly and don't meet the rules, wires that have the positive and negative poles switched, wires that aren't grounded properly, and so on can all cause lights to not work right away or after a while of use.
the leaning of lamp poles and the loose mounting of lighting fixtures can cause interior wiring to be tugged and shredded repeatedly by the wind, which could destroy the wires. If lightning protection and grounding are not done correctly during construction, LED street lights will be more likely to be destroyed by lightning strikes and will not work afterward.
