What is Super Long Constant Current LED Strip?

A Super Long Constant Current LED Strip refers to a type of flexible LED lighting product that is designed to provide a consistent and stable current to the LEDs over an extended length.

The term “Super Long Constant Current LED Strip” suggests that this particular type of LED strip is capable of maintaining a constant current across an extended length, which is important to ensure uniform brightness and color consistency along the entire length of the strip.

Why Choose Super Long Constant Current LED Strip?

With consistent current flow, the LEDs maintain their color accuracy, preventing color shifts or variations across the strip. This is crucial for applications where consistent and accurate color rendering is desired.

Constant current regulation helps prolong the lifespan of the LEDs by preventing them from being overdriven. This can result in reduced maintenance requirements and lower replacement costs over time.

The constant current regulation ensures that you don’t need to worry as much about voltage drop issues or complicated wiring configurations, simplifying the installation process. Say you can run led strips in 50 meters for one side power and 100 meters for both side.

As for Constant Voltage LED strips, such as 24Vdc LED strips, experience a drop in voltage as the distance increases, leading to reduced brightness and potential color inconsistencies along the length of the strip.

But the wiring diagram of the super long constant current led strip is straightforward, as shown below:
Therefore, the super long constant current led strip wiring is more spartan can save installation time and cost.

How Does Super Long Constant Current LED Strip Works?

A Super Long Constant Current LED Strip works by providing a regulated and constant current to the LEDs along its length, ensuring uniform brightness and color consistency. To better understand how it works, let’s break down the key components and principles involved, along with a simplified calculation diagram:

Components Involved:

  1. LEDs: The individual light-emitting diodes are the light sources. They emit light when a current passes through them.

  2. Constant Current Driver: This is the power supply or driver that provides a regulated and consistent current to the LEDs.

  3. Circuit Design: The LED strip is designed with sections or segments, each containing a series of LEDs. These sections are typically connected in parallel to the constant current driver.

Principle of Operation:

  1. Current Regulation: The constant current driver ensures that a specific current level (e.g., 20 mA) is maintained throughout the LED strip. This means that the driver adjusts the voltage it supplies to compensate for changes in LED characteristics and temperature, keeping the current constant.

  2. Voltage Adjustment: Because the forward voltage drop across LEDs can vary, the constant current driver adjusts its output voltage to provide the necessary voltage for the desired current across the entire length of the strip.

  3. Parallel Connection: The sections or segments of the LED strip are connected in parallel to the constant current driver. This parallel configuration allows each section to receive the same regulated current, ensuring uniform brightness.

Calculation Diagram:

Let’s illustrate this with a simplified example. Suppose we have a Super Long Constant Current LED Strip with the following specifications:

  • Maximum length: 100 meters
  • Constant current: 20 mA (0.02 A)
  • Forward voltage drop per LED: 3.0 V

    In this example, each LED has a forward voltage drop (Vf) of 3.0 V, and we have 10 LEDs in series within each section.


    1. Total forward voltage drop per section (Vf_total): 10 LEDs × 3.0 V = 30 V
    2. Total current per section (I_total): 20 mA (0.02 A)
    3. Voltage supplied by the constant current driver (V_driver): Vf_total = 30 V
    4. Power per section (P_total): V_driver × I_total = 30 V × 0.02 A = 0.6 W

    In this simplified example, each section of the LED strip is designed with the necessary voltage drop (Vf_total) and constant current (I_total) specifications to achieve uniform brightness and consistent performance across the entire length of the strip.
