Chapter 3: Why Do LED Lights Need Drivers?

Let’s delve into the fascinating science behind the operation of LED lights and the essential role LED drivers play. We’ll explore the physics behind it in straightforward terms.

When an LED is illuminated, heat is generated, impacting the forward voltage (Vf), which is the voltage that induces current flow in the LED circuit. Elevated temperatures lead to a reduction in voltage, subsequently causing a decline in current flow. However, LEDs require a consistent and specific current flow for optimal operation. The circuit draws more current to compensate, potentially putting itself at risk of overheating and damage.

The LED driver serves as a guardian for the LED light circuit. This compact device is equipped with a power output tailored to match the characteristics of LEDs, ensuring a consistent current flow even in the face of voltage fluctuations. Standard LED lights typically operate at low voltage (around 1.5-3.5 Volts) and current (up to 30mA). When LEDs are arranged in series and parallel configurations, they may necessitate 12 or 24V input. The crucial role of the LED driver is to convert the high-voltage AC (ranging from 120 to 277 V) into the necessary low DC voltage for seamless LED operation.

In summary, LED drivers are essential:

For stabilizing power flow in the LED circuit by transforming high input voltage and current into lower levels.
To avoid subpar performance and premature failure of LEDs.
To promote cost and time efficiency.

Chapter 4: How to Choose LED Driver?

Selecting the appropriate LED driver hinges on various factors, including the type of driver, its size, IP rating, dimmability, and more. While the market offers numerous options and variations, there’s no need for confusion as we’ve thoroughly discussed each crucial factor in detail.

A: LED Driver Types

As previously mentioned, there exist various types of LED drivers. Now, let’s explore which one suits your LED lighting needs best.

  • Constant-current LED drivers excel when powering high-power LEDs, ensuring a consistent current flow that leads to optimized brightness across a series of LEDs. This choice is rooted in the distinctive current vs. voltage relationship of LEDs. While one might assume that a higher current would result in more excellent brightness, it’s crucial to recognize that this can lead to detrimental consequences. The figure below illustrates that the current increases exponentially with small voltage increments. While a higher current might seem like a pathway to increased brightness, it jeopardizes the LED by elevating the circuit’s temperature. This heightened heat generation shortens the LEDs’ lifespan and poses the risk of premature circuit burning.

To mitigate these risks, opt for constant-current drivers. These drivers sustain a consistent current, preventing thermal runaway (where a high current leads to a temperature increase) and safeguarding the LEDs. Particularly beneficial for applications demanding high-quality illumination, constant-current drivers ensure a steady brightness output and more reliable results.

  • Constant-voltage LED drivers are recommended for LED lighting scenarios that often feature LEDs arranged in series or parallel configurations. Examples include LED linear lights, strip lights, low-voltage bollard lights, and bars. When LED series strings are interconnected in parallel, using a constant-voltage LED driver is advisable. These lighting setups typically come with instructions specifying the use of constant-voltage drivers. It’s worth noting that these lights often incorporate built-in internal constant current drivers and resistors to regulate the current effectively.

These drivers find suitability in expansive applications like signage and display boards due to their ability to produce vibrant results. Furthermore, they could be more flexible to design and present cost-effective alternatives.

B: Wattage

Considering the wattage of LED drivers is crucial as it dictates the maximum power output. We advise opting for an LED driver with a 10-20% higher wattage capability than the LED lighting product. Connecting an LED lighting product with the same or higher wattage capability may lead to premature wear of the driver before reaching its rated lifespan. For instance, if your driver operates at 80W, it’s optimal for LEDs that require 64W or less, ensuring extended lifespan and enhanced efficiency.

C: Input Voltage/Current

The significance of input voltage and current matches that of output voltage and current. Before acquiring drivers, it’s crucial to verify the voltage supply of the location. If the driver cannot accommodate the input voltage of the area, it becomes ineffective in rectifying it to the required voltage. Similarly, when opting for a constant current LED driver, it’s imperative to assess the current supply of the area.

D: Output Voltage/Current

It’s essential to align the output voltage of the LED lighting with the corresponding driver. If your lighting system operates at an output voltage of 12V or 24V, the chosen LED driver should mirror the same output voltage. Connecting a 24V driver to a 12V LED strip light can lead to a short-term, overly-brightened output, causing premature damage. Conversely, a 12V driver will not sufficiently power a 24V LED.

The same principle applies to output current. Ensuring a match between the driver’s outputs and the LED lights is vital for optimal performance and durability.

E: Dimmability

If dimmability is a requirement for your LED lighting project, it’s worth considering drivers with dimming capabilities. Dimming features can be integrated into both types of drivers through customization. Still, it’s essential to communicate your needs to the manufacturers or verify the presence of this feature in the driver’s datasheet. Dimmers within LED drivers are crucial in reducing the power supplied to the LED, influencing the overall lighting ambiance.

We recommend testing the dimmers and drivers to identify the optimal combination for your project. With advancing technology, many options are available, allowing you to tailor your choice to the project’s requirements.

A valuable tip for readers: Always request a test sample before making significant purchases, especially for large-scale investments where testing is imperative.

F: Temperature and Weather Resistance

In outdoor settings, it’s crucial to verify the IP rating of the drivers. The IP rating provides insights into the weather-resistant characteristics of the driver case. The chosen drivers should possess waterproof, dustproof, and weather-resistant attributes. For a detailed understanding of IP ratings, refer to the chart below.

ip rating standard

G: Power factor

The efficiency of LED drivers is a pivotal consideration for prolonging the lifespan of LEDs. The power factor serves as a metric for assessing the driver’s efficiency. Calculating the power factor involves using the formula:

Power factor = Watts / (Volts x Amps)

By dividing the driver wattage by the input voltage and current product, you can determine the power factor, which is measured within the range of 0-1. A higher power factor indicates superior efficiency, with a value of 0.9 or above generally considered excellent.

H: Driver Size

The physical dimensions of the drivers are of utmost importance as they directly impact the compatibility with your designated installation area. Ensuring that the drivers fit seamlessly within the allocated space is crucial, as their size plays a pivotal role in the hassle-free lighting fixture installation. Careful consideration of dimensions facilitates a smoother integration process and contributes to the lighting system’s overall aesthetics and functionality. Therefore, when selecting LED drivers, meticulous attention to their physical dimensions ensures a harmonious fit within the specified area, promoting practicality and visual appeal.
