LED Driver Replacement

LED Driver Replacement

If your LED light fixture or array has stopped working, it could be a sign that the driver is failing. Failing drivers often stop regulating power correctly, causing two issues: overdriving and underdriving.

When looking for a replacement, it is important to start by ensuring the voltage capabilities match up. After that, you will want to find a driver with similar wattage requirements.


The LED driver is a critical component of any LED light or lighting array. It converts high voltage AC power to lower voltage DC to reduce energy usage, protect the LED lights from damage and maintain steady output even during power surges. It may also provide dimming functionality.

Often the first sign of a failing driver is flickering or flashing. This is caused by the driver not being able to regulate power correctly and it can be difficult to determine the root cause without a professional inspection.

If you are experiencing this problem, you should shut off power to the breaker box and disconnect the wiring from the old driver. You will then need to unscrew the old driver from its mounting point and led driver replacement remove it from its housing. You should take note of the wire connections and their locations for reference when installing your new replacement.

Once the old driver has been removed, you can select a replacement based on its input and output voltages and current. You will also want to pay attention to the efficiency and power factor of the new driver as these are important indicators of its quality. You will want to find a driver with a high power factor that is closer to 1. A low power factor means that the driver is not converting electricity into its maximum potential output.


The central function of LED drivers is to convert a higher-voltage alternating current (AC) into a lower-voltage direct current (DC), typically running at 12v or 24v. Then they send this DC power to LED lights to make them illuminate.

When a driver starts to fail it may stop sending this power correctly and the LED lights will start to flicker or dim, this is a sign that you need to replace the driver in your fixture or array. Another common sign is that the driver starts to overheat for no apparent reason, this often happens when the internal components, such as tiny circuits or capacitors, start failing.

When choosing a new LED driver for your fixture it is important to match up the input and output requirements as closely as possible. This is especially true for constant-current drivers. Constant-current drivers will list a specific current output, often in milliamps, and a range of output voltages that it can support. The best way to determine this is to look at the data sheet from your LED lights, or ask the manufacturer of your lighting system. Also consider the features you want in a replacement driver, such as waterproofing or remote monitoring capability. You can then use this information to find the right LED driver for your system.


Most LED drivers are rated for a certain amount of current to power your lighting. This is usually noted on the label or in the product description. You also want to pay attention to the efficiency of your driver. The higher this number, the better. This is typically stated as a percentage and tells you how much more energy efficient the driver is over a standard power supply.

Another thing to look for is the output voltage. LEDs require a lower voltage than most light bulbs so your driver needs to be able to accommodate this. Analog to Digital Converter You can find this by looking at the product description or doing a quick search on the internet.

You also need to consider the size of the driver as this will determine if it will fit in your existing luminaire. Finally, you need to make sure that the new driver will be able to handle the amount of heat it will be exposed to. This is important because LED drivers can suffer from damage if they are not used at the proper operating temperature range.

Ultimately, finding the right replacement LED driver can be a challenging process. Whether you are looking for a constant current or constant voltage driver, there are many different options available on the market. The key is to match up the input and output requirements of the old and new drivers as closely as possible.


When LEDs operate, they generate heat that must be dissipated or else they will overheat and burn out. The central function of an LED driver is to dissipate this heat by converting higher-voltage AC power into direct current (DC) running at a lower Voltage – typically 12v or 24v. DC is electricity that flows in one direction only, while AC changes directions at set intervals.

The temperature of an LED driver is important because it affects its lifespan. Most drivers have a hot spot marked with a small circle on the case, which is its operating temperature limit. If it is used at temperatures close to this TC point, the driver will have a shorter lifespan than if it was operated at a cooler temperature.

There are several signs that you may need to replace your LED driver. These include if your lights are flickering, turning off or on repeatedly, and not lighting up when you switch them on. In some cases, the driver may stop working altogether. This is because it stops regulating power properly.

When choosing a replacement, make sure to double-check the wattage. You will also want to find a driver that is rated for the voltage of your network. Some will be designed to operate on specific voltages, while others will be designed to work in a wide range of voltages. If you are planning to retrofit your LED fixtures, consider looking for programmable options. These can save time and money by eliminating the need for additional trips to the electrical distributor.
