LED bulbs can flicker or buzz if the current (the flow of electrical charge) doesn’t remain constant. There are a number of possible causes for this:

1. Incorrect dimming set-up

This causes flickering and buzzing, and is usually down to using the wrong dimmer switch. Your home is likely to have a ‘leading edge’ dimmer. These are designed to smoothly dim old-style bulbs in a circuit with a range typically between 200W to 1,000W.

This is a problem for LEDs that don’t need anything like that level of current in the circuit. For example, if you switch from 4 x 60W bulbs in a circuit to 4 x equivalent brightness 9W LEDs, your total wattage has gone from 240W to 36W.

‘Trailing edge’ LED dimmers (from £15) dim on a much lower wattage and will better control your lights and avoid flickering. Make sure you check the wattage rating of the trailing edge dimmer to make sure it suits the wattage of the lights in the dimmer circuit (count up the total wattage of all of the bulbs in the circuit you are dimming). Choosing a dimmer with too low or high a range will mean that you can’t smoothly dim your new LED bulbs. 

LED dimming checklist:

  • Buy LED bulbs that state they are dimmable.
  • Check whether your dimmer switch is designed for LEDs, and calculate the total wattage in the circuit to see if it’s in the right range.
  • Switch to a trailing edge dimmer if needed. Check the LED bulb manufacturer’s website as they may have specific recommendations.
  • Avoid mixing LEDs and old-style (incandescant, halogen or CFL) bulbs in the same fitting.
  • Ideally, use identical LED bulbs (ie the same brand /spec) in one fitting for consistency. Buying multipacks, especially of LED GU10 spotlights, is often cheaper, too.

2. A high-powered appliance in the same circuit

This is rare, but if an appliance with a heavy power draw, such as an electric fan, is on the same circuit as low-power LED bulbs, it can cause flickering. 

LED bulbs require a much lower voltage (the force needed to make electricity flow) than traditional bulbs, so they have internal drivers (transformers) to reduce the voltage to the LED bulb. Turning on the fan, in this example, can cause a momentary voltage surge in the circuit.  

The flickering you see is the drivers in the LED bulbs adjusting the voltage to suit the LED. Getting an electrician to examine your circuits will be the best way to fix such a problem.

3. Loose connections

This is one of the most common causes of flickering. If you’ve eliminated other possible causes, it’s best to get an electrician to assess if this is the problem in your home.

LED lamp is the most commonly used lighting fixture in the home. Its high brightness, long life and low energy consumption are its three biggest features and advantages. However, we still have to encounter various problems during the process of using it. It can only be changed directly. Later, it was found that it can be repaired, and it is very simple, so there is no need to change the outer casing.

Do you really want to know how I repaired it? Let’s let Xiaobian take the repair of LED lights in my home as an example to introduce how to repair LED lights.
First, let’s understand what LED lights are,

    The basic structure of an LED lamp is an electroluminescent semiconductor material. It is a solid-state semiconductor device that converts electricity directly into light, places it on a leaded shelf, and then seals it with epoxy to protect it.

The role of the inner core, so the LED lamp has good seismic performance. The heart of the LED lamp is a semiconductor wafer. One end of the chip is attached to a holder, one end is a negative pole, and the other end is connected to the positive pole of the power source, so that the entire wafer is encapsulated by epoxy resin. This is the LED light.
How to repair the two LED lights?

   1 Generally, the LED lights in the house are installed on the ceiling, and they are not accessible by hand. You need to use a small ladder or a small stool to get close to it and take it off.
2 Turn on the LED lamp cover, you can see that the inside is very simple, there are power and LED lights.
3 Generally, the LED is broken. There are two cases, the lamp is broken, or the power supply is broken. If you don’t know what it is, you can buy it according to the model of your broken power supply and the length of the light. It is best to buy both, the price is very cheap. Generally, there are a few LED lights, not all of them are broken. If there are a few broken ones, buy a few lights.

When buying a light strip, pay attention to the color of the light. There is warm white and pure white. I forgot to choose it. Although the result is all white, it is not the same color as the original light. So please pay attention to this. The problem is oh.
4 light strips are connected together, carefully tear the strips away, be careful not to bend the strips.
5 First change the light strip first. If the light is still not lit, change the power supply. If the light is on, the new power supply can be placed in standby. After the power supply is broken, you can replace it. When you change the light, remember to turn off the light.
6 If you change the light strip, the light still does not light, then replace the power supply.
7 After installation, try it, the light is on, you can cover the lampshade.
