Component: 1w Led,
solar panel, battery and automatic power switch
Solar panel
This is 6V 400ma
solar panel is use to charge the battery .I use one diode between
battery and solar panel to maintain the current flow in one direction. If diode
is not there ,battery attempt to
discharge. Battery will attempt to
charge when the sun lighting.
Battery
I use 4v 500ma battery to as main power.
1w Led
I use 1w Led to
illuminate the lamp.
Automatic power
switch
This is a switch I use to illuminate bulb automatic at the
night. In this case I use LDR circuit to prevent this action. LDR can provide a
signal about current light in weather. When light is close circuits attempt to
switch is ON mode. That is theory allow in this circuit.
My Mission
Today electricity bill is vary in high. Because as a
solution I create my own lamp and circuits to maintain my electricity bill .this is
actually successful. So I’m happy about my project.
