Solar street lamps are widely used in urban and rural areas, and they are novel in style, beautifully shaped and well-structured, and are not affected by the daily impact of the general temperature brfore and after the solar cell panels. But these seemingly innocuous green light sources also contain some potential safety hazards that can not be overlooked. Knowing these potential risks could allow us to enjoy the convenience that clean energy affords us more safely.
Danger of battery safety: risks when temperature is high
The majority of current solar street lights use lithium batteries to store power, and this kind of battery will be a “time bomb” if under abnormal/unreasonable using status.
Risk of overheating: In summer it is in a high temperature environment, the temperature in the street lights battery compartment can reach 60°C, near the critical point of safety of lithium battery
Waterproof performance difference: Poor performance product has no water resistance, rainwater infiltration leads to short circuit fire
Real cases: A spontaneous combustion case of a solar street light occurred in a southern city in 2021. The blast was attributed by the investigation to overheating of low cost lithium batteries
Safety tip: Please find the item with overheating protection function and check the battery at least once a month Whether have bulged or not. If there is, please stop using the battery and replace a new one.
Design safety issues: the risk of entrapment and falling
Solar street lights poles are generally placed at the top of the poles, and the load bearing devices of the poles are compacted.
Lack of wind resistance: Some products are not designed for severe weather or may blow over in strong winds
Poorly installed: When something is poorly set, bad things become more likely to happen
failure to maintain : the long-term non-maintenance will result in structural parts rust and loose.
Warm reminder: In typhoon areas, products with wind resistance level ≥12 should be selected and professionally checked once a year.
Light pollution and traffic safety
Blind pursuit of brightness will cause unexpected damage.
Glare issue: Bad reflector or lens will be reflecting shot into the driver’s sigh；
Light pollution: Too much light in residential areas from street lights may interfere with people’s sleeping patterns
Inconsistent brightness: Some places are lighter and some are darker which lead to safety hazard
Human friendly design: A good LED solar street light should have a light that is cut with light only shining at the desired area, color temperature of 3000-4000K is recommended.
Maintenance can be electrifying.
Non-professional repair may have severe consequences pun intended
Potential residual capacitors power: System capacitors can otherwise also store dangerous power on cloudy days
incorrect use: The mistaking type of positive and negative wire causing a short-circuit条件GestureRecognizerраниц.
Note: There was a safety production accident of electric shock due to non professional maintenance in a place in 2022
Key points: Any operation of the same maintenance work should be cut off all the electricity the capacitance is released, more than 5 minutes. It’s the best to be installed by a professional certified electrician.
Buy And Apply Safety Guide
To reduce the risk, the following steps are advised:
Purchase stage:
National certification (CQC for example)
Refuse products that are too cheap to be at market level
Give priority to well-known brands
Installation stage:
Professional construction to your exact specifications
Make the height of the lamp pole and the depth of the foundation is very important and has been identified by the project.
Reserve sufficient maintenance space
Use stage:
Implement an inspection system on a regular basis (preferably semiannually)
Don’t continue to use in an abnormal situation (extremely high or low brightness, unusual noise of the lamp body)
As a model of green energy application, the safety of solar LED street lighting requires joint maintenance by producers, installers and users. Only by fully understanding these potential risks and taking preventive measures can we truly enjoy the safety and convenience brought by clean energy. Remember, no technological product is absolutely safe, and rational vigilance and correct use are the best protection.
