Peerless Emergency Tube Light Circuit
This circuit has two stages they are battery charger circuit 20 watts tube light driver circuit the battery charger circuit is constructed by using step down transformer 9 0 9 v center tapped two 1n4007 diodes are acts as fullwave rectifier and rectifies the step downed ac supply from transformer this rectified dc is filtered and regulated by variable voltage regulator.
Emergency tube light circuit. The output of the step down transformer x1 is converted in to dc by four diodes connected in bridge. Simple automatic emergency led light circuit follow us on. It prevents the user from being into an inconvenient situation due to sudden darkness and helps the user to get access to an instant make shift emergency illumination.
Tube light wiring diagram. Electronic ballast tube light wiring diagram connection and working we need tube light ballast starter and fluorescent light holders to make wiring connection. The top countries of supplier is china from which the percentage of emergency tube light circuit supply is 100 respectively.
Share on tumblr circuit diagram this full automatic emergency tube light circuit is a refer circuit from anonymous user. The tube light or fluorescent light is a low pressure mercury vapor gas discharge lamp and it uses fluorescent to produce white light. The circuit is divided in to two parts the first part is the charging unit which charges the lead acid battery.
A 6v 4 5ah rechargeable battery is connected to the array of leds through a relay. This dc voltage is used to charge the battery the dc voltage also operates the relay. The fluorescent tube has two filaments with four terminals the starter is connected between two filaments the ballast is connected between main ac.
We have used relay here to automate this. The second part of the emergency light circuit consist the main functionality that is to automatically switch on the emergency light array of white leds on power failure. Emergency light this circuit is capable of making the 20watt florescent tube light to work for four hours continuously.
