How to fix flickering led lights bulb DIY

You eating dinner, or sitting comfortably with a magazine on the couch. Flash of light, then another and another. Even if it happens occasionally, agree: blinking light in the apartment is annoying. But is it always necessary in this case to call an electrician, to wait and to take on additional costs? In some cases, the cause can be found and resolved quickly by yourself. And without any risk and without a group of tolerance of electrical safety.


Blinking led lights: why do the lights flicker

Many led light bulb, fail, burn, flicker or flash. Blink immediately and after heating, if not cease to burn until you cool down.

Change driver to new one gives a positive result, remained LEDs and aluminum heat-dissipation. The problem was the overheating of the LEDs themselves because of what the chip is deformed in a series circuit lost contact, and then the led light flashes, this problem happens with overheating

And to avoid this it is necessary to strictly observe the maximum temperature declared by the manufacturer.

1) This is the case in the backlit switch. Power switch, now it usually led lights (the old switches was backlit with neon lamp), is simply not up to the end interrupts the network. No, that is the basic electricity is still off, but the led illumination leaves the network is “closed” in itself, and that’s enough to led lamps glowed or blinked!

2) The Case in the light bulbs that flicker. Generally, a lit or blinking only low-quality bulbs, which actually do not completely meet the quality requirements. I also switch with light, but led lamps are more expensive and they do not glow after shutdown.

HOw to fix blinking led lightsMigraines can be triggered by some specific reasons, such as a flashing light. This may be a reflection from snow or water fluorescent lamp, blinking led lights, the light of the TV or movie screen. In this case, can help wearing polarizing sunglasses and indoor use fluorescent lamps outside of the spectrum of daylight.

It is believed that the human eye can perceive changes in visual information the frequency of which does not exceed 30-80 Hz (depends on individual to individual, environmental conditions, intensity and spectral composition of the luminous flux). Above this frequency, man no longer perceives the flicker visually. This parameter is called the critical flicker fusion frequency and the effect of the merger is widely used in cinema, etc.

It should be noted that for peripheral vision critical flicker fusion frequency is higher than for Central – so flicker coming from the periphery of the field of view are perceived at higher frequencies.How to fix flickering led lights bulb DIY
The visible flickering of light perceived by a man, of course, has a negative impact on the health and vision. However, because it is felt visually, the human body tries to adapt or to oppose it, forcing to limit the time of such adverse effects (e.g., discomfort when looking at the shimmering objects).

And how does vision and the brain pulsation of light with frequency above the critical flicker fusion frequency and do they represent a kind of danger? And aren’t these light pulsations cause deterioration of health in people who spend a lot of time in front of a computer monitor or in rooms with poor lighting?

There are many studies proving that the receptors in the human eye perceive light vibrations with frequencies up to 300 Hz (some sources claim that up to 10 kHz, but these figures are questionable).



How to fix flickering light

flickering fluorescent lightsGuys, how to fix flickering lights in house? It’s simple. If you bought “not the correct bulb”, you need them to either change or simply return and get a refund. Continue to buy lamps meeting the requirements of quality, such as GAUSS lamps and bulbs (not advertising), it is not a bad bulbs.


Replacing is clear! Buy switch without light and set instead of switch.

But the alteration of the switch is a little more difficult, but all easily solved! You simply delete the highlight from the switch, remove the led from the circuit! This should be done only when completely turned off the electricity in the house (through the shield)! Thus, you will have to illuminate the switch but will not light up the lamp!



Most often, the lamp starts flashing because of a malfunction of the capacitor, or its insufficient capacity. If so – to replace it is not difficult or expensive. New condenser must exceed the previous capacity in 2 times. Remove the old capacitor and solder the new to the Board.Lights-flickering

You can also connect additional capacitor, to what is already there.



Reasons for such behavior of the lamps may be several. We denote the most common. Cold cathode lamps, which are typically used for purposes of illumination, are characterized by high reliability and durability, but nothing lasts forever. One of the reasons of failure of the lamp may be getting into the air resulting from depressurization. Usually cracks appear in the glass near the contact pins. The lamp in the presence of such a defect is illuminated uniformly throughout its length, but very dim. At the ends of the lamp are formed due to the heat darkened areas. A lamp must be replaced.

blinking led lightsThe cause of the illumination of the lamp can be half open or bad soldering one of the contacts to the lamp. Usually these lights are in a protective tube made of transparent plastic. To reach the conclusions of the lamp and to check the reliability of contacts, you’ll have to pick off one of the plugs on the ends of the tube. To make sure that this behavior is to blame the bulb, not the power (it is usually called an inverter), preferably a lamp to plug in to another known good inverter or suspicious bulbs can connect a different.

Poor illumination may occur and in that case, if you lengthen the wires from the lamp to the inverter. The fact that the power Converter outputs a voltage of approximately 500-700 volts at a current of several milliamps. Moreover, this voltage is fairly high frequency (80-100 kHz). At this frequency, a large role is played by the parasitic inductance and capacitance of long wires. Elongation of wires causes a decrease in the voltage across the lamp. So, if you want to put the lamp far away from a power source, it is better to extend the low voltage wire, which is supplied to the voltage of 12V to the inverter.

And, finally, the reason for the poor performance of the lamp can be the inverter that produces it to high voltage. The inverter is built on the push-pull transformer of the oscillator. The weak point of the majority of inverters are power transistors. Usually there put a cheap low-power transistors.


The switch must stand in the gap phase, or because of interference on the wires on the lamp appears potential and it may briefly flare up. Often the switch was turned on by Murphy’s law — i.e. on the contrary, in the gap of a neutral (mistakenly referred to as “the land”).

What to do? I had to Find a remedy winks. It appeared to be a large ceramic capacitor 1 µf * 630V in parallel to the lamp squarely into the socket. Blinking stops.
