LED Emergency Light Circuit Electronic

Components List:

R1 = 180R – 1/2W
R2 = 1.2K
R3 – R14 = 100R – 1/2W
R15 = 1K – 1/2W
R16 = 16R/5W
VR1 = 2.2K
C1 = 1000uF/25V
D1-D5 = 1N4007
D6 = 6.8V – 0.5W Zener
LED1 – LED12 = Ultrabright White LEDs
T1 = BC548
T2 = BD140
B1 = 6V – 4.5Ah Rechargable Battery
IC1 = LM317
T1 = 9VAC-Transformer

You can construct the circuit on a general-purpose PCB and mount the circuit in a plastic with enough space for battery and switches. Mount the LEDs on the cabinet such that they light up the room. A hole in the cabinet should be drilled to connect 230V AC input for the primary of the transformer.

This schematic diagram come from circuit: Ultra Bright LED Emergency Light.

In the electrical sector, a schematic diagram is usually used to describe the design or model of equipment. Schematic diagrams are usually utilized for the maintenance and repair of electronic and electromechanical devices / units. Original schematics were made by hand, using standardized templates or pre-printed adhesive symbols, but nowadays Electrical CAD computer software is often used.

In electronic design automation, until the 1980s schematics were virtually the only formal representation for circuits. More lately, using the progress of computer system technology, other representations were introduced and specialized computer languages were developed, because with the explosive development of the complexity of electronic circuits, classic schematics are getting less practical. As an example, hardware description languages are indispensable for contemporary digital circuit design.
