Since solar energy is completely natural, it is considered a clean
energy source. It does not disrupt the environment or create a threat to Eco-systems the way oil and some other energy sources might. It does not cause greenhouse gases, air or water pollution. This is a small problem compared to the huge impact that one oil spill can have on the environment.

There for i think Solar Panels have become such a good option for saving money so try to protect our mother nature...!

We Need...

First you need to make the circuit as shown in the diagram.

in this circuit i use BC547 transistor instead of D880 because of its more sensitive than D880 transistor

if you use 2pcs of 6v solar panels wire them serial type.
The battery is self protected from discharge because a 6v relay can't turn on with less than about 6V, and it's overcharge protected because of the solar panel is about 12V 500mah , and the maximum battery voltage is about 7.4V 5000mah it can cover 10hours day time.(its well over than the real sunny day time)

then you need to make the led panel more accurately

Making the Led Bulb..

You can get 5730 smd chips from old chinese led bulb

then remove then from the circuit & solder them carefully

after that you need to add 20ohm resistor

finally attach them to the bulb casing, now the bulb is ready to use ...

Making Battery Pack..

You need 4pcs of 18650 batteries & holders

then take some screws and attach those holders to the dot board strip

finally add a little amount of hot glue to screws

Assemble Parts to Lamp Cover & Finishing Touches...

After making all electrical items please recheck all of them before set them to the cove
then you need to add them to the lamp cover

therefor first you need to atch main circuit and other wires into the lamp cover

Then you can attach PIR sensor and bulb to it ,

After that solder the solar panel to wires

then cover all the joint with pvc tape or heat shrink tube

then add some hot glue and cover the PIR sensor for protect it from water


after that attach the solar panel on to the lamp cover by using hot glue

finally fit the cover with nut & bolts

Test and Close-up the Lamp...

After attach them all add glass plates and other decorations plug your mobile phone or any USB plug type to the

socket then you can see its charging

cover the solar panel & move any thing near the PIR sensor then you can see blue leds start to flash and after short period they turn off

then you can assemble it in a any place you like by using a pipe...
