When the street lights on the road you pass by every day are not working, you may feel annoyed. Who should you report when the street lights don’t work? How are these street lights maintained? In this article, we have mentioned the 6 most common LED street lighting problems and corresponding solutions. Reading this article, you can also learn who to contact when you find a street light failure and how they maintain the street lights.
1. Street light not working
There are several possibilities that cause street lights to not work:
- If the street lights turn off at an irregular time point, the reason of the fault can be unstable voltage. Usually the street light will recover by itself after the voltage stabilizes.
- If the street light does not light up on time, it may be due to a control system failure. A light control switch failure or a timer failure will cause the street light to not light up according to the light or its schedule. Replacing the sensors or timers with new ones can make the lights work again.
- When the street lights on one side cannot light up, it is necessary to check whether the power switch is working normally and whether there is excessive current or leakage. This issue could possibly be due to the control system. Maybe the signal line is not intact or the control setting is incorrect.
- When several street lights at the end of a line do not light up, it is possible that the cable is burned or cut.
- When a single street light does not light up, we should first check whether its power supply is working properly and then check the lamp head components. The radiator, LED chip, and power driver inside the lamp are likely to break down. If the power supply provides abnormal current or voltage, the street lights cannot light up. LED chips with poor quality may provide light with uneven brightness. In addition, poor heat dissipation may also cause damage to the lamps.
2. What does it mean if the street lights are on during the day?
Street lights are rarely turned on during the day. One possibility is that the light control switch doesn’t work, causing the street light to light up automatically even during the day. A more likely situation is that the workers are maintaining and testing the street lights. Since the personnel will cut off the power while maintenance, they often inspect and test the street lights during the day to avoid affecting the street lighting at night. The purpose of lighting up the lights for a short time is to detect the effect of the repair.
3. Why are street lights turning on and off by themselves?
If street lights often turn off automatically when it is still dark, it is also a problem with the control system. In addition to the photosensitive controller and timer mentioned above, automatic street lighting system can also cause faults. If the centralized street light controller or software system fails, all street lights under its jurisdiction will be out of control. At the time, these lights need manual intervention. To fix this problem, make sure the wiring connectors of the intelligent equipment are tight. Using high-quality controller and protect the wires of the single-lamp controller can avoid this kind of problems in advance.
4. Why do street lights flicker at night?
The main reasons for the constant flickering of street lights are:
- Loose lamp head: If the lamp head has poor contact, the current transmission will be disturbed, causing the street light to flicker.
- Power supply of poor quality: When the driving power supply cannot provide a stable current, it will cause the street light to flicker.
- Line fault: If there is a short circuit or aging lines, the current will become unstable and cause the street light to flicker.

5. Why is the street light buzzing?
If the street light makes a buzzing sound, it is very likely that the street light you see is an HPS lamp. The ballast in the HPS street lighting system will make a buzzing sound when the iron core is loose. If the noise is too loud, it may be due to the burnout of the lamp head wire, and it needs to be repaired as soon as possible. LED street lights rarely make noise.
6. Rust and tilt of street light poles
When the streetlight pole has traces of rust and cracks and isn’t repaired in time, it is easy to break. Such street light poles only use plastic spray paint and may easily break down after a long period of use. Now the street light poles are mostly galvanized and have a longer service life.
If the street light pole tilts, there is generally a problem with the base steel plate used to fix it. During installation, workers will ensure that there is no distortion in the steel plate of the street light base. Besides, the cement base on the ground should be tight. If you notice such street light pole, do not approach it and contact the relevant department in time.
Who should I report street light problems to?
Street lights in different areas are managed by different municipal agencies or power companies. You can try to contact your city’s transportation bureau, power bureau, engineering bureau, property management company, etc. to get a response.
How are the street lights maintained?
- Regular inspection and maintenance: Regularly inspect road lighting facilities, including checking the integrity of components such as bulbs, circuits, lampshades, and light sensors.
- Check lamps: Replace damaged bulbs, light sensors, and other components in time.
- Check the power connection and cables of lamps: Make sure that the cables are not broken, short-circuited, or overheated. Replaced or repaired the broken wires in time.
- Maintenance and cleaning: Regularly clean the street lights lampshades to increase the brightness and lifespan of street lights.
- Regularly test the illuminance: Regularly test the illuminance of road lighting facilities to ensure that it meets the lighting
Conclusion
Common problems with street lights include not lighting up, flickering, turning off/on at the wrong time, making noise, and damaged poles. For these problems, we usually check the problem one by one from the circuit to the lamp and replace the damaged parts. Maintenance personnel will regularly check the operation of street lights, but they may not find the problem in time. If you find any of the above faults, please do not approach rashly and contact the relevant department as soon as possible.
