Why do fluorescent lamps only have a very dim shimmer?

If the fluorescent lamp only has a very faint light, it means that the lamp is about to break. When the fluorescent lamp is just turned off, it will continue to emit a faint light (pale green or off-white), which is a normal phosphor afterglow phenomenon that will disappear for about a minute. If the light glows faintly long after the light is turned off, check whether the switch is incorrectly connected in the neutral line.

Rubbing the nylon skin with your hand will bring high-voltage static electricity, so that the thin electrons in the lamp will accelerate the movement, and hit the mercury atoms to cause the radiation ultraviolet rays to excite the phosphor to emit light. Since there are very few electrons, it emits light weakly.

When energized but there is no starter, because the filament is not preheated, the ability of the filament to emit electrons is poor, and the lamp mainly relies on high-voltage static electricity to ionize the inert gas and conduct electricity, so the current in the lamp is smaller, the luminous efficiency is lower, and the lamp is darker.

The luminescence of fluorescent lamps is produced by electrons striking mercury vapor to produce ultraviolet light, which then irradiates the phosphor on the inner wall of the lamp to excite it to produce visible light. At the moment of turning off, due to the difference in temperature and the luminous inertia of the phosphor, it will emit visible light at night, but it is very faint, as is the phosphor screen of the TV set. After a long time, it will be gone.

Some fluorescent lamps still have a very dim glimmer after turning off the light, this is the zero line controlled by the light switch, and there should be no glimmer when the live wire is controlled instead.

It should be that the lamp is going to be broken, try another one.

Because fluorescent lamps only want to be bad, there will be a very dim shimmer.

If the fluorescent lamp only has a very faint light, it means that the lamp is about to break.

Hello dear! What's going on with the dim light line of the sun at home? 1. The solar light panel is faulty.

For example, the solar lamp beads are burned, and the solar lamp panel is disconnected or connected incorrectly. You can disassemble the shell of the solar lamp, check whether the lamp beads are burned with a multimeter potato belt, etc., if the lamp beads are burned, we can replace the lamp beads with new ones. If the line is disconnected or misconnected, we can reconnect the line.

2. The solar panel is faulty. If the solar panel fails, the battery cannot be charged, so the solar light does not light up. You can remove the damaged solar panel and replace it with a new one3. The solar battery is faulty.

The service life of the battery is limited, and if the battery has passed its service life, the solar lamp may not be lit. You can replace the expired battery, and it is best to choose a lithium battery when replacing the battery, which has a longer service life. 4. The solar controller is faulty.

A malfunction of the solar controller will cause the solar lights to not turn on and off normally. Generally, if the control megameter fails, its indicator light will light up, I hope it can help you!

Dear, hello, I'm glad to answer for you, what is going on with the dark light line of the household A: I summarized the following points for you: 1. The setting of the controller is to control the lighting time and brightness of the solar street lamp, and the controller setting will often be adjusted according to the daily lighting time of the local street lamp and consider the number of rainy days and other influencing factors.

If the setting of the solar street lamp controller does not match the actual local situation, especially in some rainy places, if you want to ensure that the lighting is always on, Heng Rotten will turn down the brightness of the street lamp to save electricity. 2. When the power of the solar street lamp is too small, if the power of the battery panel is too small, it will cause the battery to be stored insufficiently, so the power consumption of the street lamp is too large when it is used, and the battery is not on the power, which will cause the lack of light. 3. The aging battery of the battery is the energy storage place of the solar street lamp, if the battery is aging and damaged, then there is no power storage, so that the solar street lamp has no power to provide, or there is a weak power supply, which will cause the lack of light of the solar street lamp or the phenomenon of inability to illuminate.

4. Low absorption efficiency of solar panels, for example: large trees are planted near the solar street lamp, and the big trees block the solar light source, which will cause the solar street lamp to be unable to obtain electricity, and it may be because the solar panel of the solar street lamp is moved, and there is no sunrise that cannot absorb the energy of the sun, and the solar panel is blocked will also cause insufficient light. 5. The impact of the weather on solar street lights is still very great, solar street lights are to absorb sunlight during the day to convert electricity to store electricity, and use the electricity stored during the day at night, so that it has been circulating, but if there is no sunshine for many days, cloudy days or rain and snow weather, then the street lights will lose their power, so that the stored power will be used all the time, and when the stored power is exhausted, or it is less and less, the light emitted by the solar street lights will be very weak, This will cause a lack of light.
