What is Super Long Constant Current LED Strip?

An SUPER-long constant current LED strip refers to a flexible LED strip equipped with a constant current IC. The primary function of the constant current IC is to maintain a steady current over extended lengths, ensuring that the brightness and color consistency remain uniform throughout the strip, even over longer distances. Available in lengths such as 15, 20, 30, 40, or 50 meters, this type of strip can maintain consistent brightness from start to end with single-end power supply, eliminating the common issue of voltage drop in longer strips.

How Does Super Long Constant Current LED Strip Works?

Before explaining how super long constant current LED strips work, it's important to first understand the difference between constant current and constant voltage LED strips.

What is a Constant Voltage LED Strip?

A constant voltage LED strip operates with a fixed voltage while the current fluctuates depending on the position along the strip. This variation in current often results in brightness and color inconsistency, especially towards the end of the strip, as the current weakens.

What is a Constant Current LED Strip?

In a constant current LED strip, the current remains stable throughout the length of the strip. This consistent current ensures that the brightness and color remain uniform from the start to the end of the strip. The constant current IC embedded in the strip helps maintain this stability, allowing it to run over long distances without significant voltage drop or light dimming.

How Does a Super Long Constant Current LED Strip Work?

The ability to run an LED strip over long distances without brightness loss is due to its constant current IC. Here’s a breakdown of how these components function together:

PCB (Printed Circuit Board):
The PCB serves as the physical structure and electrical conductor that connects the various components. The design typically includes several groups of LEDs (e.g., 6 LEDs per group or 8 LEDs per group), ensuring a well-distributed current and uniform brightness.
LED Chips:
When current flows through the LED chips, they emit a steady light. The quantity and arrangement of the LED chips directly influence the overall brightness and appearance of the strip.

Constant Current IC:
The constant current IC regulates the current flowing to the LED chips, ensuring each chip gets the right amount of current. This is crucial for maintaining consistent brightness throughout the strip and avoiding any voltage drops that would typically cause dimming at the far ends.

Why Regular LED Strips Suffer from Voltage Drop:

Standard LED strips, built with LEDs, resistors, and a PCB, experience voltage drops because the PCB has some inherent resistance. As current passes through the PCB, the resistance causes voltage loss, converting some of the energy into heat. The wider the PCB, the lower the resistance; however, the longer the strip, the more significant the voltage drop. Selecting the appropriate PCB width and length can reduce resistance and, in turn, minimize voltage drops.

Why Choose Long Constant Current LED Strip?

The long constant current LED strip works by limiting the operating current through an integrated constant current IC, ensuring that each LED receives the required current, which guarantees consistent brightness across the entire length of the strip, no matter where the LEDs are located. Here are the main reasons why choosing an ultra-long constant current LED strip is beneficial:

Long-Distance Power Supply

Long LED strips can maintain stable voltage over long distances without experiencing brightness reduction due to voltage drop. This provides more flexibility in covering large areas with a single power source. Available lengths include 10m, 20m, 30m, 40m, and 50m, making it easier to cover extensive setups.

No Voltage Drop

Unlike standard LED strips (e.g., 12V or 24V),super-long constant current strips can illuminate over long distances, such as 30 meters or more, while maintaining consistent brightness from end to end. This eliminates the need for additional power sources along the strip, which is typical with traditional strips.

Uniform Brightness

The constant current feature ensures that brightness remains uniform, avoiding the issue of brightness inconsistency seen in constant voltage LED strips, where the light near the power source is often brighter than at the end.

Energy-Efficient, High Brightness, and Safe

LED technology is inherently energy-efficient, consuming significantly less power compared to traditional incandescent lighting. Despite their lower power consumption, LED strips deliver high brightness. Moreover, these strips operate on low voltage, making them a safe option for a variety of lighting applications.

Ease of Installation

With longer LED strips requiring fewer power supply connections, installation becomes easier, saving time and labor costs. Single-end power supply for long strips minimizes the need for additional power boosters, simplifying the setup.

Long Constant Current LED Strip Application

Due to their long length, consistent brightness, and ease of installation, long constant current LED strips are widely used in various lighting applications. With IP20, IP64, IP65, and IP67 protection levels, they are suitable for both indoor and outdoor use in multiple industries.

1. Residential Applications

Ambiance Creation: More and more buildings use constant current LED strips to create ambiance, provide supplementary lighting, and enhance the depth of space. These strips are frequently used to outline the contours of iconic structures, such as high-rise buildings, bridges, and parks, creating a beautiful, illuminated silhouette at night.
Highlighting Architectural Details: They are ideal for accentuating architectural elements such as balconies, windows, and exterior features, contributing to the overall lighting design and visual appeal of buildings.

2. Commercial Applications

Retail and Hospitality: In commercial spaces like malls and hotels, constant current LED strips are favored for their high color rendering index (CRI) and uniform lighting. They play an important role in decorating and defining space with linear lighting, enhancing depth, and creating a comfortable environment with warm tones. This makes them especially valuable in hospitality areas like lobbies and retail displays.
Custom Lightscapes: These strips are often used to outline the contours of various spaces, providing visual appeal and making commercial settings more inviting.

3. Other Applications

Bridges, Roads, and Gardens: Constant current LED strips are perfect for outdoor lighting applications, including bridges, roads, gardens, and patios. Their ability to maintain consistent brightness over long distances makes them ideal for decorative lighting in large outdoor areas.
Decorative Signage: The strips can also be used for advertising signs, logos, and billboards, where long, consistent, and colorful illumination is needed. The various color options add versatility to outdoor displays, creating different atmospheres for different occasions.
Water-Resistant Applications: With waterproof options (IP67, IP68), they can be used in ponds, underwater features, and outdoor pools, offering a creative lighting solution for both decorative and functional outdoor spaces.

FAQs

Here are top asked questions, feel free to contact us for more details.

Do LED strips need constant current?

No, LED strips do not necessarily need to be constant current. Typically, constant voltage LED strips (such as 12V or 24V) are more common and sufficient for most general lighting applications. However, constant current LED strips are preferred in situations where higher-quality, long-distance strips are required, as they help to maintain uniform brightness across the strip and prevent voltage drop issues, which can cause the LEDs at the far end to dim.

What are constant current LEDs?

Constant current LEDs are LED strips with a constant current IC, ensuring the current remains constant.

Why drive white LEDs with constant current?

LED constant current power supplies offer higher stability by maintaining a consistent current output under varying voltage and temperature conditions.
