In modern life, one cannot do without such a thing as an energy-saving lamp. As its very name says, the feature of these lamps is the economical consumption of electricity, but at the same time it produces quite good light emission, which naturally saves your finances. Many people are interested in the circuit and the device of an energy-saving lamp , which we will gladly provide in this article.
Externally, the LED lamp, often, is not much different from the usual incandescent filament. So, for example, they have an identical base. The difference is only in the glass shell and the fact that under it. The housekeeper has an electrical circuit inside, while the incandescent lamp has only two contacts and between them a tungsten filament.
At the moment, incandescent bulbs are gradually beginning to leave the market, in their place come fluorescent and LED.In some countries, they have generally ceased to be produced, but in the CIS countries still have some popularity.
Device and principle of operation
What is the secret of energy conservation of these devices. This question interests many people. However, there is nothing difficult in the design of such lamps. It can be said that the energy-saving lamp is a reduced copy of a fluorescent lamp, which we know from the Soviet Union. But unlike their counterparts, they are installed in a conventional cartridge and are used for both general and additional lighting.
All energy saving lamps are very similar in their design and consist of several parts:
- The gas discharge tube is the part that emits light, usually made of glass;
- Case - a gas-discharge tube is connected to it, in the case there is a power supply circuit and a microcircuit;
- Base - also attached to the body and its purpose is to create contact and supply electricity to the microcircuit of the bulb.
We describe each detail in more detail. So, the simplest part is the gas discharge tube. It is made of Plexiglas and a gas is flowing through this tube, which, when in contact with electricity, radiates ultraviolet light. Gas can be used differently: Neon, Argon, Krypton, Xenon. The shape is also different. Outside the tube is covered with a special protective substance that is not advisable to wipe, otherwise the light bulb will not work in due time.
The base of an energy-saving lamp carries the contacts for powering the lamp and the thread itself for connecting to the socket. Almost identical with the incandescent lamp, has the same look and even material. In Russia, lamps with such bases are common: GU10, G4, E40, E27, E14, G5.3.These bases are used in everyday life for general and additional lighting.
The case is made of special non-flammable plastic. A lamp bulb and a base should be attached to it, thus making a single unit out of the lamp. Inside the case, as mentioned above, there is a power control and monitoring circuit, and a noise protection filter that protects against power surges in the power grid.
Disassembly and Diagnostics
To get to the device chip, you just need to open the case cover. The case is divided into two parts, which are fastened together with a snap and, if necessary, easily removed. We recommend disassembling an already unusable lamp, since when disassembling a working one, there is a chance to bring it to a faulty state. At first glance, the lamp is solid and cannot be disassembled, but it is not. If you carefully inspect the case, then you will see a special groove, which you can easily open the case with a knife or screwdriver, but this should be done without sharp movements.
Once you have separated the two parts from each other, you can see that they are interconnected by a pair of wires. They must also be carefully disconnected from the chip, which can be done with a soldering iron by soldering the desired ends from the board. Sometimes, on some lamps, the ends of the wires are wound on the contacts, so you can simply unscrew them. Now you have on hand two separate parts of the light bulb.
The electronic board is usually round and has either yellow or green color. This electrical circuit is the main control device of an energy-saving lamp. If the lamp burned out, then on the board one can observe swollen and drained capacitors, as well as burnt contacts. To the board from the bulb go four wiring, which are wound on the contacts. Usually they are located on the ends of the board in the opposite direction from each other. In different light bulbs, either a fuse or a resistor is used that does not allow the light bulb to burn, and it burns itself. Next you can see the choke and capacitor. They control the flashing frequency of the lamp. The circuit itself is designed to regulate and control the ignition of the lamp, its glowing temperature, as well as to prevent voltage surges.
That's all you need to know about the device of your home energy-saving lamp.
Indicating all the main aspects of the work, and the internal structure of the energy-saving lamp, we summarize - these devices are much more practical and economical than their predecessors, incandescent lamps. They are safer and more profitable financially. Therefore, in spite of its rather high price, we advise you to purchase these lighting fixtures, since they will pay for themselves a lot in the course of their use.
We hope that this article has given you a concept of what constitutes an circuit and device for an energy-saving lamp. Be careful when choosing a way to save electricity in your home.
