How to choose LED drivers for LED street light?

What is an LED driver?

LED driver is the heart of LED light, it’s like cruise control in a car. It regulates the power required for an LED or array of LEDs. Light-emitting diodes (LEDs) are low-voltage light sources that require a constant DC voltage or current to operate optimally.LED driver converting the high AC mains voltage to the required low DC voltage, provides protection to the LED bulbs against current and voltage fluctuations. Without the correct LED driver, the LED would become too hot and result in burnout or bad performance.

LED drivers are either constant current or constant voltage. Constant current drivers provide a fixed output current and may have a wide range of output voltages. Constant voltage LED drivers to provide a fixed output voltage and a maximum regulated output current.

How to choose the right LED driver?

Outdoor lights must withstand harsh conditions such as lighting, hail, dust clouds, intense heat, and frigid cold, so it’s important to use a reliable LED driver, below are son popular reliable LED driver brand:
