Let's start with the fact that relatively recently a fairly promising direction in the field of artificial lighting has appeared. This direction is characterized by the fact that an LED is used as a light source.

LED lamps are semiconductor devices that distort electrical voltage, due to which a glow effect is obtained. Such light sources are more often used for street lighting. For example, for buildings, tunnels, streets, bridges, fountains, cultural monuments and the like. Why? They just give off a lot of power.

The use of LEDs in residential premises has the format of designer lighting. Most LED lamps have a spectrum that is not very good for the retina.

LED lamps have many advantages over conventional lamps. Namely:

1. Small energy consumption.
2. No UV radiation.
3. Does not heat up during use.
4. Long service life.
5. Does not harm the environment.
6. Resistance to mechanical damage.
7. Light weight.
8. Instant warm up.

Despite all the positive aspects, LED lamps have several disadvantages:

• quite expensive relative to energy-saving lamps or incandescent lamps;
• the glow of LEDs attracts invertebrate inhabitants of the fauna;
• inability to work at high temperatures;
• a spectrum of luminescence not quite suitable for painstaking work;
• even new appliances may start flashing.

At the last point, we will dwell in more detail and find out the main reasons why the LED lamps are flashing.

Why does the LED blink when off?

There are two reasons that contribute to the fact that the device flashes when it is turned off. Namely:

1. Using a switch that has an LED light. The current that flows through it can charge the capacitor over time. As a result, a weak glow occurs.
2. Use of LED lamps that do not meet quality standards.

Why is the LED blinking when on?

First of all, the blinking of the LED lamp in the on state can be provoked by its poor-quality installation. In this case, it is worth checking well all the contacts in the electrical circuit of the conductors.

Another important factor is a properly organized power supply system. Quite often, LED lamps flash in houses with an old wiring system.

The flashing of the device in the on state indicates that the switch is not in phase, but at zero. Another possible reason for the periodic flashing of the lamp may well be a phase imbalance. In such a situation, voltage appears in the “0” wire.

How to fix blinking LEDs when on

In most cases, an electrician will help determine and eliminate the cause of the flashing lamp. After all, he has not only the relevant knowledge, but also the necessary tools for work.

If you decide that you want to repair the device yourself, you must first familiarize yourself with its structure. It has some differences for each device. Therefore, you can drive exactly your LED model in the search engine and look at its design. After that, it is worth applying a general set of measures that will help eliminate flashing. Namely:

• it is necessary to get the filling of the device and insert the driver there (a special device that converts electrical signals);
• it is necessary to solder another capacitor into it to stabilize the device (the most budgetary repair option);
• one driver should be used for all bulbs in the device.
