Tube lights are most used light source and here tube light connection circuit and wiring diagram given with explanation. Tubelight electronic choke this is an electronic choke for a conventional fluorescent lamp.
Electronic Ballast For Fluorescent Tubes 8 144w
Tubelight electronic choke circuit diagram. When supply is provided the starter will interrupt the supply cycle of ac. The diodes npn transistor and caps are high voltage 350v 1kv the tubelight is 40w 60w 5 feet long. The tube light or fluorescent light is a low pressure mercury vapor gas discharge lamp and it uses fluorescent to produce white light. This was an application note of mje13005 a high voltage switching npn power transistor. A choke is connected in one end of the tube light and a starter is in series with the circuit. Connection of tube light is very simple because it has few wiring points only.
What is use of choke in tubelight. The function of choke is to provide high voltage enough for ionization to take place in a tube light and after establishment and substenance of ionization limit. In electronics a choke is an inductor used to block higher frequency while passing direct current dc and lower frequencies of alternating current ac in an electrical circuita choke usually consists of a coil of insulated wire often wound on a magnetic core although some consist of a doughnut shaped bead of ferrite material strung on a wirethe chokes impedance increases with frequency. Electronics articles 8 aug 14. One terminal of choke or ballast is connected to port 1 and another terminal is connected to pin 1 of terminal 1. Twin 40 watt ballast circuit diagram.
