Automatic Emergency LED Light | General Electronics Projects

Model No. 297: This automatic emergency led light used in night time when the power is cutoff by some reason. This emergency light takes 230V AC and it converts it in 12V DC and charge the battery which is used in this circuit. In this circuit we use PNP transistor. The advantage of this emergency light is that if we use this light in a room with LED light source for high energy conversion efficiency.
