9 Factors To Choose LED Power Supply For Street Lights

In the past 10 years, LED lamps had a significant impact on the beauty of the city and its landscape. The most important thing for LED street lights on city streets is the LED power supply.

Therefore, we have years of research and work experience in LED power supply design, Here list 9 important factors for choosing LED street lamp driver.

1. Input Power -Wattage:

The power of LED street lights is usually between 50W and 300W, so it is necessary to choose a LED power supply within the corresponding power range.

Above Picture is Model: BA-804 Series LED Power Supply.

2. Input voltage range:

Select the appropriate LED power supply according to the voltage range of the actual use environment.

Generally speaking, the input voltage range of LED street lights is AC 100V-265V, so it is necessary to choose a LED power supply that can adapt to this range.

Above Picture is Model: BA-904 Series LED Power Supply.

3. Output current and voltage:

Select the appropriate LED power supply according to the operating current and voltage requirements of the LED street light. The operating current of LED street lights is usually between 300mA and 1500mA, and the operating voltage is usually between DC 12V and DC 48V. Therefore, it is necessary to select a driving power supply that can provide the corresponding current and voltage.

4. High efficiency and stability:

Choosing a LED power supply with high efficiency and stability can improve the brightness and life of LED street lights.

Generally speaking, a high-efficiency driving power supply can reduce energy loss, and a stable driving power supply can ensure the stable operation of LED street lights. We can do more than 95% Efficiency. Such as our model BA-509N7 Series LED Power Supply.

5. Protection function:

Choosing a LED power supply with over-current protection, over-voltage protection, short-circuit protection and other protective functions can improve the safety and reliability of LED street lights. Beon LED drivers are full with these protection function.

Here we also did another blog to explain:Over Voltage Protection In LED Power Supply. You can have a look too.

6. Quality and reliability:

Choosing a LED power supply with good quality and reliability can reduce failure rates and repair costs. You can choose products from reputable and experienced suppliers, or choose products that have passed relevant certifications.

Beon LED Power supply are all pass CE, CB, FCC, Rohs,CCC, ENEC… Certification.

7. Waterproof Level:

LED street lamp power supply is mostly working in the outdoors, but the outdoor environment is relatively harsh,like heavy wind and rain, then its waterproof is particularly important.

Beon LED power supply can do IP67 waterproof. When we do LED driver packaging, we must first evacuate the air to exhaust all the air in the potting glue (epoxy resin) , prevent the electronic parts inside from oxidizing. At the same time, our driver housing structure can achieve true IP67 waterproof rating.

IP67 waterproof rating means that the product has level 6 dustproof & 7 waterproof capabilities.

Dust level 7 means that the product can completely prevent dust intrusion, effectively prevent the intrusion of particles larger than 1mm.

Waterproof level 7 indicates that the product can be submerged in static water at a depth of 0.15 to 1 meter for 30 minutes, but not for a long time.

8. Dimming Function:

As a new generation lighting source, LED is very suitable for using intelligent dimming methods to further save power.

We can flexibly set the dimming method and time according to specific lighting projects and specific road traffic conditions.

For example: Some of the city’s remote roads, when there are few people and vehicles on the road in the late night, LED street lights can be operated at about 40% power. On the main roads in some urban areas, the power can also be appropriately reduced in the late night, which not only ensures people’s basic requirements for travel, but also saves electricity.

If LED street lights want to achieve power reduction dimming, a dimmable LED power supply must be used.

At present, dimmable LED power supplies are generally divided into two types: one is AC phase-cut dimming, and the other is 0-10V DC signal control dimming(PWM dimming).

9.Use environment:

A. The LED power supply of LED street lights works outdoors in a poor environment. The temperature changes greatly throughout the year. The sun is exposed to the sun in summer, the cold is severe in winter, and it has to withstand the impact of heavy rain and lightning strikes, so various tolerances need to be considered.

For some government projects, it is asking for 6KV or 10KV surge protection. Beon can offer SPD (Surge Protective Device) 10KV & 20KV.

B. There are high-power high pole lights and lower-power garden street lights, some with mains voltage, some with low voltage, and some in areas with frequent lightning strikes, so the LED power supply choose not only has good constant current performance, but also has heat dissipation. Good, it can withstand lightning strikes and rain.

Conclusion

choosing a suitable LED street light power supply requires considering factors such as power, input voltage range, output current and voltage, high efficiency and stability, protective functions, quality and reliability. According to the actual needs and usage environment of LED street lights, selecting a suitable driving power supply can ensure the normal operation and long life of the LED street lights.
