LED Globe is a light consisting of 240 LEDs, which gives a very pleasant light, at the same time lighting up the whole room. It is suitable to be hung in your Drawing room, Dining room or Bedroom. It runs on 12 volt 1 Amp. AC Transformer connected to the house mains of 220 or 110 Volts.

Step 1: Things you will need: -


One AC Transformer of 220 to 12 volt AC, 1Amp.

240 Bright White LEDís size 5mm.

Mild steel wire to make the supporting rings.

Electrical thin wire, solder etc.
5mm Iron Rod to make the HOOK.

Step 2: Construction of the GLOBE


Make 3 Big Rings out of the Mild steel wire of the same size and 2 small rings of same size.

Tie up the 2 Vertical rings with the Horizontal ring with thin wires as shown in the illustration. Take care to see that there is no electrical connection between the Vertical and Horizontal Rings.

Wrap cello tape around the Horizontal rings to make it a bad conductor to Electricity.

Now tie up the 2 small rings, one at the top and the other at the bottom of the GLOBE.

Take care so that there is no electrical contact between the Big rings and the Small Rings.

Step 3: Circuit for the LED's

Circuit for the LEDís.

Here we will be using two types of LED circuit for this project.

8 Double Row and 8 Single Row of LEDís.

5 LEDís have been used in one ROW becauseÖÖÖÖÖ

12v x 1.4 = 16.8

16.8 divided by 3.5v = 4.8 or say 5 LEDís. in one row.

12 volt AC has been provided to 5 plus and 5 minus LEDís. In the Double Row LEDís.

The same 12 volt is connected to the single rows, See Diagram.

Step 4: Placement of the Rows

It is shown in this Diagram the placement of Double and Single Rows of LED's.

Step 5: Rows of LED's

In this step we see as to how the Rows of LEDís are connected to the wire frame.

After each Double Row of LEDís a Single Row of LEDís are placed to fill up the gap in the GLOBE.

In the Double Row LEDís the top and bottom are soldered to the two small rings at both ends and the middle (5 LEDís) are soldered to the Horizontal big ring.

The 2 Small rings are connected to one Terminal and the Horizontal big ring is connected to the other Terminal of the 12volt Transformer.

Step 6: Transformer


Place the Transformer in a box fixed to the Hook from which the LED GLOBE is to be hung in the room.

Plug in the Transformer to the mains and enjoy the light.
