I wanted to experiment with a lot of LED;s on AC mains, and this is the result. I have used 160 white LED's for this project and it has been a success.It gives a bright light and is suitable for the Drawing room, or the Dining room.'You can have a Candlelight dinner without the candles.Hang it from the ceiling and you have a decorative light. It is easy to make and is also cheap.
Step 1: STEP-1
List of parts.1. Extra bright white LED's =160 pieces2. Motorcycle Wheel SPOKES = 4 pieces3. Perforated Hard board of required size = 1 piece4. Stepdown Transformer 220 volts to 12 volts 1 piece of 2 Amps.(Used in Stereo Amplifier)5. Male Electrical 2 pin PLUG = 1 piece.6. Solder wire.7. Connecting Electrical wires as needed.8. Tools for Electronic wireing.
Step 2: STEP-2
Use a piece of perforated hardboard for support and fix 5+5 LED's with the correct polarity as shown in the photo.
First bend the legs of the LED's and then Solder all the legs of the LED's as shown in the diagram.
4 LED's should be soldered at the centre to give supporting strength to the LED's.
After soldering all the 10 LED's push it out of the support hardboard.
Make 16 set of 10 LED's that is, in Total 160 LED's.
Step 3: STEP-3
Follow the WIRING diagram as shown in this Photo.
Take care to maintain the Polarity at all times.
Step 4: STEP-4
Take a 2 pieces of Hardboard of the same size and fix a wooden batten between them to make a thin frame.
Fix The Motorcycle spooks at 4 corners of the board.
Solder 4 sets of 10 LED' s on one side to the wire frame as shown in the photo, while maintaining equal distance for all the sets of LED's
Connect the 2 opposite ends of the wire frame with an electrical wire.
Fix the Transformer with nuts and bolts on the top side of the Hardboard frame.
Connect the Positive and Negative wires from the output of the Transformer as shown in the Photo.
Connect a 2 pin Plug to the input of the transformer.(220 Volts AC)
Fix 4 Nylon ropes at the 4 corners to hang the whole project from the ceiling.
Hang the thing, plug it in and your job is done.
Now you can enjoy a candlelight dinner with your loved ones.
Step 5: STEP-5Here in this step i would like to answer some of your questions..
There is a very minimum of flicker which is not noticeable because the pair of LED's are close together.
The flicker I get is as much as a 4 feet Fl. Tube light burning.
