That used to be the past and old era when illumination used to be carried out via incandescent lamps but owing so many demerits of it, these have been replaced by the fluorescent tube. If we talk about the fluorescent tube then it also regarded as a FL that refers to the fluorescent lamp and its another form has already been arrived in the market and is extensively used under the name of CFL i.e. compact fluorescent lamp.
However, there are such a lot of diversities that may be seen in both the form of FL but there?s one thing that being common among both of them and so has to do with the fluorescent light fixture. It is the plate or we may call it as a socket in which the fluorescent lamp is affixed. There are 2 more electrical equipments connected in series connection with the tube on this fluorescent light fixture and they?re the electrical starter and the choke which is also called the ballast if it is electronic type.
Now another question arises that what is the usage of these electrical equipments on this fluorescent light fixture? These have not been connected without any reason and there is a technical reason behind it. If we talk in regards to the ballast then it?s an electronic device that can be seen connected in series with the fluorescent tube. This is so because these tube works on the principle of electrical discharge. Electrical discharge is the phenomenon f the movement of the electrical charges between the two electrodes with gas as a medium between both of them. In this tube, there are 2 electrodes and there?s certain gas in between both of them at excessive high pressure. So as to case discharge between both of them, there?s a need to have voltage up to 1000 volts at the electrodes.
As we now that across the fluorescent tube, the normal voltage level that we provide is only 220-230 volts. If this voltage level is not enhanced for a while, the discharge can?t take place and hence tube will not work. So as to enhance the voltage level for a while, ballast is connected in series with the tube and is visible on the fluorescent light fixture. Similarly, so as to provide, excessive resistance to cause voltage drops, starter is connected in series that offers high resistance in the very beginning and then gradually, the normal current is passed to the tube. There are so many forms of totally different fixtures available in the market like open type, closed type, compact type etc.
There are quite a few firms that manufacture both fluorescent light fixture and fluorescent tube but amongst them, there are only few that are regarded as a standard and one among them is the Crompton and Grieves. As far as this firm is concerned, it?s an India based company and is regarded as the largest electrical equipment firm across the country. Its yearly turnover is more than one billion dollars. Its offices aren?t restricted within the geographical boundaries of India but has been scattered across the world like in Canada, Ireland, Indonesia, USA, etc
Kohsun is one of the leading companies involved in the manufacture of fluorescent luminaires, components and accessories in Malaysia under the brand name of K. S. LITE. We manufacture a wide range of fluorescent fittings from economical batten fittings to high effic iency VISUAL DISPLAY UNITS ( VDU ) pre-anodized aluminium parabolic louvers fittings including custom made fixtures of special design for special application.
