This is a “SPIRAL LED CHANDELIER” with 240 LED’s working on AC current.
It looks very decent when you switch off all the room lights at night.
Gives a soft light throughout the room and you can use it while watching TV.
Hang it in the Dining room and have a candle light dinner.
This is a sister model of my instructables “LED CHANDELIER” posted earlier.
Step 1: STEP-1
Take a piece of Mild Steel wire of 1/8 inch diameter and 12 to 14 feet long.
Wind the wire into a spiral with a hook at the top.
This is used as a support for the LED Necklace and the Transformer.
See the Photograph for guidance.
Step 2: STEP-2
In this step connect the LED’s as shown in the circuit diagram.
I have taken +8 & -8 LED’s in 2 rows so that it can be powered by a 16 volts 1 Amp. AC Transformer.
The calculation is as follows:
16 volts transformer without load shows 18 volts output.
So 18 x 1.4 =25.2volts
25.2 volts divided by Led voltage 3.5. = 7.2
OR say you can use +8 LED’s per row, and –8 LED for the next row.
16 led x 15 times is 240 LED’s in total can be powered by this Transformer.
Take care to connect the LED’s as per the polarity shown in the circuit diagram.
Step 3: STEP-3
Now you have 15 sets of 16 LED’s. Join them together and make a
LED Necklace out of it.
In this step connect the set of 15 LED’s in parallel to the transformer output.
See Diagram for guidance.
The Input of the Transformer is to be connected to your house voltage of 220 volts. AC.
Step 4: STEP-4
In this step you can see the close up Photograph of the LED Necklace.
The electrical wires run along with the LED Necklace.
Step 5: STEP-5
In this step Insulation PVC Tape is wound around the
steel wire to make it insulation proof.
You can also use flexible plastic sleeves for this purpose.
The Transformer is tied to the steel hook by locking wires.
