How does the fluorescent lamp work and the main accessories of the fluorescent lamp are explained in detail
How does the fluorescent lamp work? In the fluorescent lamp circuit, the current starts from the left pin of the plug and flows through the rectifier, One filament of the tube, the closed switch in the starter, and the other filament in the tube, finally flow out from the right prong of the plug. The current heats two small elements at the ends of the fluorescent tube, and the starter turns on to pass the current through the fluorescent lamp.
The rectifier is a magnetic coil that regulates the current flowing through the lamp. When the starter is turned on, an arc surge will pass through the tube, and then after the tube has fired, the starter will keep the current flowing at the correct rate. In most fluorescent lamps, the starter is an automatic switch. When it detects that the lamp is glowing, it will always be in a disconnected state. As long as the power to the lamp is disconnected, the starter will turn off.
Many fluorescent lamps contain multiple tubes to provide better lighting. These fluorescent lamps must have a separate rectifier and starter for each tube. The light fixture may look like two tubes sharing a rectifier, but it may actually be two rectifiers built into a box. Similarly, lamps with four tubes are equipped with four starters and four rectifiers. In some types of lamps, the starter is built-in and cannot be replaced separately.
Because there are only three main parts to fluorescent lamps, all repairs and replacements can be done by yourself, all fluorescent lamps will gradually dim over time and may flicker or flicker, these are warnings Signal, as soon as you notice any change in normal performance on the fluorescent lamp, you should make the necessary repairs immediately, the dimmed lamp tube usually needs to be replaced, failure to replace the lamp tube may cause damage to other parts of the lamp, again, constantly The flickering will consume the starter, which will cause the insulation layer of the starter to age.
If the tube is not faulty, please try to replace the starter. Fluorescent starters are rated by power, so it is important to use the correct starter for the tube in the fixture. The method of removing the old starter is the same as removing the old tube, by turning it to take out the lamp socket, when installing the starter, just insert it into the socket and turn it to lock in place.
The rectifier is also rated according to the power, like the spare starter, the spare rectifier must match the type of lamp power lamp. The rectifier is the component with the least possibility of failure and the most difficult to replace, so please leave the rectifier at the end when you start replacing parts. If the lamp and the starter are not faulty, the problem must be the rectifier, and the faulty one needs to be replaced. For the rectifier, please power off the circuit first, disassemble the lamp, then switch the wires from the old rectifier to the new rectifier, (one at a time to avoid mistakes) and finally reassemble the lamp.
If the lamp, starter, and lamp are all normal, but the fluorescent lamp still does not light up, please check whether the switch is faulty. If the fluorescent lamp is controlled by a wall switch, please replace it switch, which will be explained in the next section. If the fluorescent light uses a push button switch, you can replace the old switch with a new switch of the same type. To de-energize the circuit before operating the switch, remove the fuse or disconnect the circuit breaker.
