The CFL was initially designed to replace the incandescent lamp in terms of its compactness as well as energy efficiency. A CFL uses vacuum pipe which is principle wise same to the strip lamps commonly known as Tube light. Tube has two electrodes on both ends which is treated with Barium. These accelerated electrons strike Mercury and Argon atoms which in turn results in the arise of a low temperature plasma.
This process initiates the radiation of Mercury in Ultra violet form. This tube is fed with AC power supply which facilitate the changing functionality of Anode and Cathode.
The CFL also consists a switched mode converter. It functions on a very high frequency and acts as a replacement of ballast choke and starter assembly. Though being compact, it efficiently performs the requirements as a choke. The circuit of CFL is explained in succeeding paragraphs. The starter segment comprise of a Diac, C2, D1 and R6. The components D3, R3, D2 and R1 work as a protection circuit and the rest as normal operation circuit.
You have to keep the following terminology in mind :. As soon as the operation starts, the D1 diode blocks the whole section. Capacitor C2 is also discharged after charged to its full value each time the transistor Q2 operates. Therefore after its first start, There is not enough energy left for reopening of Diac. Further, the transistors are excited with the help of TR1 transformer. As the voltage is raised from resonant circuit L1, TR1, C3 and C6 , the tube lights up as soon as resonant voltage is specified by capacitor C3 which feeds Filaments.
Another significant issue that hopefully will be solved some day in the future is the lifespan of a compact fluorescent light bulb. In most of the cases, these bulbs are made to last around hours, but if you are turning them on and off too often, the lifetime of a bulb will decrease significantly. Keep in mind that fluorescent light bulbs are more fragile and sensitive especially in low and high temperatures. Moreover, since they contain mercury, keep in mind to apply some safety methods if using the bulb outdoors to protect it from different external elements damaging the bulb.
The dangers of mercury being released when breaking the bulb is one of the main arguments why many people still refuse to use compact fluorescent light bulbs. However, if utilized properly, the advantages still outweighs the disadvantages, ensuring that switching to CFL bulbs will have long-term benefits, mainly by notably reducing your electricity bill.

The potential of organic solar cells 10 May, All you had to do was take the fluorescent tube and twist it into a spiral spring, right?
Making the actual fluorescent tube smaller was no problem. Creating a smaller and more compact ballast was the real challenge, especially when it came to integrating it with the lamp itself. What is a ballast? Find out here. A non-integrated ballast is the type of CFL technology that we typically call a "plug-in. This is similar to linear fluorescents but is far smaller than a linear ballast. The integrated ballast CFLs are created to replace incandescent and halogen lamps. Literally, take out the incandescent or halogen bulb and put in a CFL bulb in the same socket.
BUT, do incandescent and halogens need a ballast? So, in order for these CFLs to work in a regular medium base screw socket, a ballast has to be integrated into the CFL. The most common reason people use compact fluorescent bulbs is to save energy. However, there are some other applications for these lamps that you see quite often.
