Guide: The LED patch light, also known as SMD LED light, is a type of lighting solution that is mounted directly onto a circuit board or rigid PCB. Many people may be unfamiliar with this kind of lighting. Generally, LED patch lights are very flexible and soft, made from materials such as PCB or FPC. They offer high brightness and wide illumination angles, typically exceeding 120 degrees, ensuring even lighting distribution. Their compact and elegant design makes them ideal for various applications. However, when an LED patch light fails, how can it be replaced? Let's explore the details together!

How to Replace a Broken LED Patch Light
1. If the power supply of the LED patch light is damaged, you can purchase a new power source with the same voltage and current specifications to replace the old one.
2. If multiple LEDs in the same area are damaged, you can cut off the faulty section and re-solder the good parts back into place.
3. If you have some basic electronics knowledge, you can buy identical LED components, use a soldering iron, and re-weld them. However, keep in mind that most LED strips contain many small LEDs. If just one or two are damaged, it usually doesn’t significantly affect the overall brightness.
Why LED Patch Lights Can't Be Repaired
LED SMD lights are generally not repairable due to their compact and integrated design. When they don’t light up, it’s usually because of either a faulty light source or a power supply issue. Most LED patch lights use SMD LED chips as their light source. To check, first, turn off the power at home, open the lamp cover, and use a multimeter to test if the LED source is broken (they are usually connected in series). If the source is faulty, look for a matching LED chip on Taobao or other platforms, and make sure to choose the same voltage rating when purchasing.

If the LED source tests fine, then the problem might be with the power supply. Most LED patch lights use an external power adapter. In that case, simply replacing the power supply should solve the issue.
What Is an LED Patch Light?
LED patch lights, or SMD LED lights, are constructed using FPC (Flexible Printed Circuit) boards, LED components, and high-quality silicone casings. These lights are waterproof, safe, and easy to use with low-voltage DC power supplies. They come in various colors and offer vibrant illumination. Outdoor models are designed to resist UV aging, yellowing, and high temperatures. This versatile product is widely used in architectural contour lighting, entertainment venues, decorative lighting, and advertising displays.
