Constant Current LED Driver For LED Street Light Modules

LED street lighting has become the go-to choice for cities and municipalities worldwide due to its energy efficiency, longevity, and environmental benefits. To power these street lights effectively, constant current LED drivers play a pivotal role.

In this blog, we’ll delve into the significance of constant current drivers and explore their features and applications.

Understanding Constant Current LED Drivers:

  1. What Are They?
    • Constant current LED drivers provide a consistent current output to LED modules, regardless of voltage fluctuations.
    • Unlike constant voltage drivers, which maintain a fixed voltage, constant current drivers ensure that LEDs receive a steady current within a specific voltage range.
  2. Why Are They Essential for Street Lights?
    • LED street lights often consist of multiple LED modules connected in series or parallel.
    • Constant current drivers ensure uniform illumination across all modules, preventing overcurrent or voltage spikes that could damage LED. 

        3. Features of Constant Current Drivers:

      • Precise Current Regulation: These drivers maintain a specific current (e.g., 1500mA, 700mA) to match LED requirements.
      • High Power Factor: With a power factor greater than 0.95, they minimize energy losses and improve overall efficiency.
      • Low Total Harmonic Distortion (THD): THD remains below 15% throughout the line and load cycle.
      • Quasi-Resonant Mode: This mode optimizes efficiency and reduces stress on components.


What are the pain points of modular lamps on the market now?

The LED light module is a lighting fixture that integrates : LED lamp chips, circuit control, housing and other components. It has the characteristics of small size, good luminous effect, energy saving and environmental protection, and is widely used in indoor and outdoor lighting fields. Wiring is one of the key steps in using LED light modules.

  • How to avoid the risk of electric shock when wiring?
  • How to deal with weak wiring or poor contact?

Correct wiring methods can ensure the normal operation and safe use of LED light modules.

BEON provides convenient wiring led drivers for modular lighting fixtures,which not only improves work efficiency but also greatly improves safety performance.
