In our lives, fluorescent lamps should be said to be more common lamps. In many family rooms, most of them will be lit by two or more lamps. Basically, there will be fluorescent lamps, which can be emitted more than many lamps. It also needs bright light and soft light, which has been widely used. Let's take a look at the common troubleshooting steps of fluorescent lamps !
fluorescent lamp
First, the lamp does not shine at all
In this case, you can check the following steps:
1. Start other indoor lighting fixtures to see if the power supply is normal.
2. If the power supply of the road is normal, use the test pencil to check the switch terminal to see if the contact is good.
3. Use both hands to turn the lamp holder at both ends of the lamp tube a few times or turn the lamp tube to check if the lamp holder is in good contact with the lamp tube pin.
4. Rotate the starter to check whether the contact performance of the starter and the starter seat is good.
5. There is no thick oxide layer on the surface of the starter foot. If there is any oxide layer removed, the wiring between the components is intact.
Fluorescent lamp common fault
Second, the two ends of the lamp flash, can not be normally illuminated
1. It may be that the voltage of the whole circuit is insufficient. At this time, other lamps in the room can be turned on. If the light is found to be darker than usual, it is sure that the circuit voltage is insufficient. After the power supply is normal, it will return to normal.
2. It may be that the starter is faulty. At this time, a new starter can be replaced. If it is an emergency repair, there is no new starter on hand. You can remove the opener shell and connect the paper capacitors in parallel with the jumper. Cut it for emergency use, but you must replace it with a new starter as soon as possible.
3, the indoor temperature is too low in the cold weather, the lamp is difficult to take off. At this time, you can use a hot towel to stick back and forth in the middle of the tube. Never touch the aluminum shell at both ends of the tube with a wet towel to prevent electric shock, and the tube can normally emit light.
Third, the two ends of the tube are red, and will automatically go out soon.
Fluorescent lamp common troubleshooting
1. If the lamp is used for a long time, gradually blackening from the two ends, to red, there is a gradual process, basically the lamp is aging, the filament is about to blow off the precursor, and the lamp can be replaced to eliminate the fault.
2, the use of the lamp has been normal, the above phenomenon suddenly occurs, which is mostly caused by the failure of the rectifier, the rectifier can be replaced.
