'Garden Lamp Schematic 2012'. In the first schematic edition, i want to give you simple circuit schematic of Garden Lamp. I say that it is simple circuit schematic because only need little component to make it. Although it is simple circuit schematic, but it is very useful in your live. You can use Garden Lamp Schematic to help you operate your garden lamp turn on and turn off automatic. 

Simple Operation:

Garden Lamp Schematic make your garden lamp turn off automatic in day but in the night your garden lamp will turn on automatic. I think it is very nice, you must not turn on or turn off your garden lamp manually. It is also help you if you must go anywhere, your garden lamp will operate automatic.

Component List: 

1.   D1 - D4        ----  IN 4004

2.   R1                ----  2M2 ohm *

3.   LDR

4.   SCR             ----  FIR3D 

Note: you can change R1 to adjust sensitivity of light sensor.

How the Circuit Schematic Work?

You can make this circuit easily. This circuit need AC 200V for input with 50Hz. D1 - D4 will make AC to DC for circuit. R1 and LDR is Voltage divider to make trigger of SCR. So you can adjust of R1 to make different of voltage divider. SCR will make circuit turn on or turn off depend of voltage divider and it is make Bulb Lamp turn on or turn off. 

Note: this circuit only for Bulb Lamp not for Tube Light Lamp. If you want use Tube Light Lamp you can use relay or other circuit.
