Why do energy saving lamps flicker and flicker, and why energy saving lamps flicker

Is the light flashing after turning off, if the light will flash after the light is turned off, it is the problem of the lamp, that is caused by saving a resistance in the energy-saving lamp line, many small factories do the lamp have this problem, because due to the tiny current of the power switch or the distribution capacitance between the lines so that the power supply of the switch is still formed a loop, there is a weak current flowing through the energy-saving lamp, through the electrolytic storage of the energy-saving lamp, when the trigger voltage of the energy-saving lamp is reached, it is a flash, and the electricity on the electrolysis continues the next round of charging and dischargingIt is very simple to deal with, that is, on the energy-saving lamp internal electrolysis (470-820K) or the energy-saving lamp with DB3 trigger diode line, a 270-390K resistor can be connected in parallel at both ends of the capacitor of tens of NF connected to DB3.

When the fluorescent lamp is working, the argon gas in the tube ionizes to generate heat, and the heat causes the mercury to produce vapor, and then the mercury vapor is also ionized and emits strong ultraviolet rays. When excited by ultraviolet light, the phosphors inside the tube wall emit near-white visible light. After turning off the light, the temperature of the lamp is still relatively high, so the mercury vapor is still there, and of course it will look flickering.

2;The tube of an energy-saving lamp is a gas-discharge lamp that emits a faint fluorescence when it induces an electric field. When the phase wire (live wire) of the power supply is not connected to the switch but the neutral wire (ground wire) is connected to the switch, although the light is turned off and there is no current, the lamp is still connected to the phase wire, the potential is high, and there is an induced electric field, so the light is turned off and flashes again and again. It can be solved by reconnecting the switch to the live wire.

The same is true for my family, and then I came to the electrical store to ask, they said that it was a problem with the rectifier, and then I changed the rectifier, 12 yuan, the problem was solved, it turned out that it was the problem of the rectifier, and the above answers were not correct

It must be caused by the unstable voltage of the lamp.

Switch issues. It would be nice if the switch had a small light to guess him.

Line issues. Then you have to be professional.

The strobe phenomenon in a short period of time is a normal phenomenon, which is due to the effect of phosphor in the energy-saving lamp, but the phenomenon of strobe occurs for a long time, which may be caused by the switch connected to the zero line or the power indicator on the switch. If it is caused by the indicator light, then there is no big impact, we just need to remove the indicator light on the switch.

If the live wire on the switch is broken, there is still a strobe phenomenon, then the zero line is electrified, which may be due to the open circuit of the upper zero line, or due to the serious imbalance of the local three-phase load, resulting in the neutral drift of the zero line, and the practical need to solve the strobe phenomenon by balancing the three-phase load.

The reason for the strobe of energy-saving lamps may be due to the fact that when the power cord is connected at the place of the main switch, the neutral wire and the live wire are reversed, and because the capacitor inside the ballast of the energy-saving lamp can store electrical energy, it will lead to the phenomenon of strobe when there is a weak current passing through the circuit of the diode. In this case, we only need to disconnect the main power supply and switch the neutral wire and the live wire on the main switch.

If the flicker phenomenon occurs in the electronic energy-saving lamp, it may be due to the failure of the electronic rectifier on the energy-saving lamp, the diode in the rectifier filter circuit may be damaged, or the capacitor leakage, etc., which may cause the flicker.

In addition, we can also check whether there is a high-power RF source near the energy-saving lamp, which is due to the phenomenon that high-frequency radiation can also cause the energy-saving lamp to flicker.

Electronic energy-saving lamps have electronic rectifiers, energy-saving lamps are lit when the strobe, generally caused by poor electronic rectifiers, and there are many reasons for strobes, such as individual damage to the diodes in the rectifier filter circuit, capacitance leakage, resonant capacitor leakage, etc., which will cause stroboscopy, it is recommended to find some electronic ballast maintenance information on the Internet to see, refer to it.

Unstable voltage fluctuations; The lamps are aging and the grid frequency is unstable. Energy-saving lamps and "fluorescent lamps" are a class of lamps, which work on the same principle and have the same faults.

The starting voltage is low, and it is generally not easy to break.

The LED lights or energy-saving lamps at home will flash after the power is turned off, usually because the power supply is connected to the zero line at the beginning, and the solution is to change the power supply to the live line of the power supply. If it still flashes after changing the beginning to the line of fire. That is, the switch leakage or the connecting wire of the switch has leakage.

This tiny leakage enters the electronic ballast of the energy-saving lamp to rectify the energy storage accumulation, and carries out an abnormal lighting work, and repeats again and again. If it is only a flash due to a problem in the design of the electronic ballast, there is still a voltage in the electronic ballast after the power is turned off, and when the voltage drops to a certain value, it is just right to make the lamp light up.

1. It may be caused by the aging of the lamp, you can try to replace the new lamp, if it is still flashing, it is not the cause of the lamp, you can ask a professional circuit maintenance master to investigate, do not deal with it yourself, so as to avoid danger.

2. It may be caused by rust and aging of the lamp feet, and you can check whether there is moisture around. You can put some dehumidifying things around the perimeter to prevent moisture aging.

3. It may be that there is leakage in the line, which can be detected with an electric pen. If there is indeed a leakage problem, it is recommended to ask a professional circuit maintenance master to repair it.

4. It may be that the line is reversed, especially whether the connection of the zero live line corresponds. It is recommended to ask a professional circuit repairer to rewire and repair the circuit.

Advantages and disadvantages of knots and rotten energy lamps.

Advantages: 1. Energy saving and money. Energy-saving lamps are called energy-saving lamps because they are more energy-efficient than other lamps in the past. And it has low power, saving 70%-80% of electricity compared with incandescent lamps.

2. High light efficiency and great benefits. Under the condition that the illuminance remains the same, an 11W energy-saving lamp directly replaces the 60W incandescent lamp. An 85W high-power energy-saving lamp can replace a 500W incandescent lamp or a 250W mercury mercury lamp. Its energy-saving rate reaches 50%-80%.

3. Wide working voltage: 170V-250V is suitable for China's power supply needs, long life, and the average service life is 8000 hours. No noise, no flicker, no interference to communication and household appliances. 80% less electricity than ordinary incandescent bulbs.

4. Long service life. The inner wall of the lamp is coated with a protective film and a triple screw filament, which has a life of 3-10 times longer than that of traditional lamps.

5. Small size, beautiful shape and easy to use. Due to the high power load of compact fluorescent lamps, it is small and beautiful in size, and also has a good decorative effect, beautiful shape and various uses. For example, the large lamp in the hall, the small lamp in the bedroom, the miniature lamp in the hallway, and the table lamp on the table are all very beautiful.

Eye-catching energy-saving lamps and colorful lights can give the living room a decorative beauty.

6. Energy-saving lamp technology is advancing with each passing day, and the luminous efficiency of energy-saving lamps is making amazing breakthroughs, and it is also constantly decreasing.

Disadvantages: 1. The energy-saving lamp starts slowly.

2. Energy-saving lamps are bright line spectrum, so the usual energy-saving lamps are purple, and the things under the energy-saving lamps will be seriously discolored. Blue will turn purple, and red and yellow will become more vivid. Therefore, CFLs should not be used for color matching work.

3. After long-term investigation and research, scientists have come to a preliminary conclusion: the radiation of energy-saving lamps may have an impact on human health.

In this case, the life of the energy-saving lamp has ended, and a component has been broken, although the lamp beads or lamps are not broken, and it is better to replace them with new ones.

The main reason is that the service life of energy-saving lamps is up, and the electronic components on the circuit board are in an unstable working state, only to replace the bulb or lamp, if it is an electronic ballast, it is necessary to consider changing the electronic ballast. In the case of inductive rectifiers, only the lamp needs to be replaced.

If the energy-saving lamp flashes when it is turned on, it is basically an energy-saving lamp, and it should be a precursor to failure. It is recommended that you turn off the light first, and then fix the bulb again to see if it is loose.
