How to maintain and clean fluorescent tubes? Precautions for the use of fluorescent lamps
Fluorescent lamp is a kind of fluorescent lamp with very beautiful colors. It is not only widely used in home decoration, but also has very good effects in some hospitals, clothing stores, shopping malls and other places. It not only has good lighting effects, but also highlights some colorful items at night. . So how to maintain and clean the fluorescent tube? What are the precautions for the use of fluorescent lamps? Don't worry, BENWEI will explain it to you, let's take a look.
How to maintain and clean fluorescent tubes
1. Don't switch the lights too frequently. Too frequent lighting will cause the two ends of the lamp tube to become black prematurely, which will affect the output power of the lamp tube, and it should be noted that it will take 5-15 minutes to restart the lamp after turning off the lamp.
2. If the voltage is very low, the two poles of the lamp tube will emit tungsten at the beginning of lighting, so that many dot-shaped pollutants are generated inside the lamp tube, which becomes one of the reasons for the damage of the lamp tube. Therefore, it is recommended to keep the lamp as high as possible. Turn on the light under voltage.
3. Fluorescent lamps have many lines and need auxiliary devices, so they must be used in conjunction with corresponding transformers, capacitors, etc. to ensure that the lamp tube starts to a suitable power.
4. Pay attention to maintaining a ventilated environment, not only to take away the dust, but also to reduce the temperature of the lamp, so as to extend the life of the lamp.
5. Fluorescent lamp heat is easy to attract dust. When preparing to clean, turn off the power, and then try to let the indoor air circulate, use a wrung out cloth moistened with a little detergent and gently wipe the lamp tube, and then use a clean dry cloth to remove the detergent Wipe clean.
6. If conditions permit, you can use an anti-static duster to remove the dust on the surface of the lamp, and then wipe the dirt with a dry cloth, not too hard.
7. Use paper towels to clean your hands in accordance with the fluorescent lamp, do not leave marks on the lamp, and you can also wipe the surface of the lamp with alcohol to keep it clean.
Precautions for the use of fluorescent lamps
Stroboscopic effect
The fluorescent lamps used in our country are generally 220V, 50Hz AC power supply. When a fluorescent lamp is working in an AC circuit, with the change of voltage and current, the light emission also changes periodically, which changes 100 times per minute. This phenomenon of change is called stroboscopic effect. Because of its fast changing speed, it is difficult for ordinary people to feel it when observing a fixed object. But observing moving objects, you will find obvious flicker. Therefore, it should be noted that it is not advisable to observe fast-moving objects under fluorescent lighting.
Pay attention to improving the efficiency of use
After the fluorescent lamp has been used for a period of time, under normal circumstances, both ends of the lamp tube will slowly turn black and the light will gradually decline. If the lamp tube on the lamp holder is turned 180 degrees before use, it can not only increase the luminous efficiency, but also delay the blackening time and prolong the service life of the lamp tube. The lamp tube tends to turn black at the section close to the ballast wiring. If the lamp tube is turned around and used after a period of use, it will also help to extend the life of the lamp tube and improve the efficiency of the lamp tube.
Pay attention to timely replacement of the lamp
Fluorescent tubes will gradually age due to the passage of time, the luminous ability will gradually decline, and the luminous flux will decrease significantly. Compared with the luminous flux of a new lamp tube with blackened ends, the difference is about double. Therefore, when the fluorescent tube has been used for a long time, the two ends of the fluorescent tube should naturally turn black, and the new tube should be replaced. Because the luminous efficiency is too low in that way, the normal illuminance drops, and the phenomenon of jitter often occurs. It is not economical and can easily damage eyesight in severe cases. Moreover, because the emitting material on the cathode has been exhausted, the lamp tube is difficult to start, and the starter needs to be repeatedly bounced before the lamp tube can be started. In this case, if the lamp tube is not replaced in time, the starter is often damaged, and the ballast is overheated, which affects safety.
