Common LED Driver Problems and How to Solve Them


Have you experienced the frustration of flickering or dimming LED lights that will stay lit? You are not alone. While LED lighting is more durable and energy-efficient than its traditional counterparts, it may malfunction over time due to issues with the driver. This component regulates electrical current and voltage supplied to the lights and ensures everything runs smoothly.

As your premier supplier of top-notch LED driver power supply in the Philippines, Ecoshift Corporation is here to help. Our experts will listen to your concerns, get to the root of the problem, and determine the best course of action to fix your driver. Keep reading as we tackle some of the most common LED driver problems with their simple solutions to get your lighting system shining bright again.


Solving Common Problems With LED Drivers

Most LED power supply issues are easy to resolve. However,  some may require the expertise of a professional. If you encounter any warning signs, it is best to fix them immediately before it is too late. Watch out for the following problems:


Dimming Problems

Have you ever noticed that sometimes when you try to dim LED lights, they do not dim evenly? This is called “dead travel,” which occurs when the driver is not fully loaded.

As a rule of thumb, you should use an LED driver 12v with a power rating of 20 to 30% higher than you need to cope with the potential overload. However, you will likely run into a dead travel issue if you do this with a constant voltage LED power supply. We suggest using more than 90% of the LED driver’s load to achieve a smoother and broader dimming range.

If you have too many LEDs for a single power supply, you can split the load and use multiple drivers, but ensure each driver is loaded to the same level.


Driver-Fixture Mismatch

If you just installed the LED driver only for the lights to flicker, flash, or be not as bright as they should, chances are you are running into incompatibility issues.

For instance, if you use LED downlights, note that they come with built-in electronics that regulate electrical current, meaning they need a constant voltage 12v LED power supply. As a result, a driver with pulse width modulation (PWM) output will not work.

Now, why does this happen? Well, with PWM, the output of the LED driver is being cycled on and off quickly. This causes the downlight’s integrated electronics to struggle to keep pace with the switching frequency.

Ecoshift can help you prevent this problem in the first place by recommending the right LED driver power supply in the Philippines for your LED lighting system. We also recommend testing the power supply with your light fixtures before installation.


Overheating and Overloading 

Like other electronic devices, LED drivers become less efficient as they get hotter. If the temperature gets too high, you may need to reduce the load on your component. Furthermore, ensure it operates within the specific temperature range and that heat can be convicted.

Besides that, consider the derating of the LED power supply. Even if the actual load is lower than the maximum power output rating shown in the data sheet of the LED driver transformer, it can still get overloaded.


Surge Immunity Failure

Lightning strikes can create high voltage surges in the electrical supply, exceeding your LED driver’s maximum voltage rating and causing it to fail. For this reason, many LED power supplies come with surge protection features to withstand these occurrences.

To avoid surge immunity failure, the LED driver’s input port and the lamps’ AC power port must meet specific requirements set by the international standard IEC 61000-4-5. This includes withstanding surges of up to 2KV between line and line and 4KV between line and ground.

On top of that, you should make sure that your LED power supply is grounded correctly and that any impact energy has a clear path to dissipate. Meanwhile, if you are setting it up outdoors, we suggest using a dedicated power line and avoiding having large mechanical or electrical equipment nearby that could cause surges.


Reasons LED Power Supplies Fail 

Although LED drivers last several years, they can prematurely fail due to various problems. You can prevent most of these issues by taking proactive measures and seeking professional help when necessary.


Installation Issues 

It is not enough that you get the best LED driver out there. You should also ensure it is installed the first time correctly so it can function as expected. Otherwise, it may overheat, overload, or short-circuit, causing it to break down. Some common installation errors include:

  • Poor Wiring
  • Incorrect Voltage
  • Improper Grounding
  • Overloading

Always follow the manufacturer’s instructions when setting up the LED power supply. Check if the wiring is correct, the voltage is appropriate, and the power supply is properly grounded. When in doubt, you can also leave the job to our pros at Ecoshift instead.


Environmental Issues 

LED power supplies installed outdoors are more susceptible to breakdowns due to prolonged exposure to harsh conditions, such as debris buildup, poor ventilation, high temperatures, and excessive humidity.

While most environmental problems are beyond your control, you can take steps to protect your LED driver. Install it in a well-ventilated area away from moisture and dust. If the environment is too hot, consider setting up a fan or choosing a power supply rated for higher temperatures.
