Introduction: SPIRAL LED CHANDELIER

About: Now I am a retired person, who enjoys life and making small things to pass the time keep myself busy.

INTRO

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

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

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

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

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

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.


Step 6: STEP-6

STEP-6

Connect all the electrical wires and hang it from the ceiling fan hook.
Switch on and ENJOY…………………………….

I HAVE BEEN USING THIS FOR THE LAST 3 MONTHS, NO PROBLEMS.

    Whoa! This is spectacular! Something like it would look so good hanging in my stairway. Looking at the photo of thre 240 LED necklace in Step 4 made me wonder if strings of LED lights [Christmas or other] would work? I'm not mechanical, and altho' you've laid it out so carefully I'm even less electrical. :-)

    Multiplying Factor of 1.4 used in STEP 2 is for AC. Is the same Multiplying factor of 1.4 applicable for DC supply? Satpathi

    Multiplying Factor of 1.4 used in STEP 2 is for AC. Transformer to find out the numbers of LED to be used in one segment.

    For DC you do NOT need to do this because you already know the DC voltage, so divide the LED voltage 3.5 by the DC voltage and you get the number of LED per segment....

    wow...this is really epic....my wife gonna love it for the dinning room....if I ever have the patience to make something like this....

    This thing is epic. But I dont think my parents would let me put this up anywhere if I built it. Well, my mom was looking for a new lighting fixture for our dining room. Nah, she still wouldnt.

    Hi TOCO,
    Tell your parents that this is a VERY SAFE Project as it runs on only 12 volts.
    Getting Shocked Dose not arise.

    Oh, Im not worried about that. I just dont know where to put it if I built it. I have worked on plenty of dangerous things before. I dont have anywhere close to an outlet either. for some reason my house has a lack of electrical outlets by my standards. Im sure that it probably has more than most houses.

     yaar deepankar how have you joined the leds in zigzag motion?

    kucch aur use kiya hain kya uske saath or bas directly 2 leds ko unke connectors ko ek saath solder kar dia hain?

    chandelier accha hain.. but din me utna hi bhadda hain :) well how uses it during the day anyways.. accha project hain.. will be making soon as i finish up with my aieee... but usme ill put alternate color leds :)

    Step 3 ka photo dekho,
    Hum ne perforated hardboard ka use keya hai jo LED ka support deiya hai soldering ke leya.
    LED ko hole me dal do, phir uska legs ko bend karo aur solder karo.

    haaaa haaaa haaaaa
    L..D ko hole me dal do, phir uska legs ko bend karo aur solder karo.
    lolzzzzzzzzzzzzzzzzzzzzzz

     samajh gaya.. accha hain.. dhanyawaad.. sab log spanish etc me baat kar rahe the.. toh maine socha kyoun na main bi apni matra bhasha ka prayog karu idhar :-)

    Tum ne bedi samajdari ke baat ke.
    Main Bangla, Hindi aur Oriya ma bhe baat kar sakta huin.
