18 LED Light Bulb for "extra" brightness !!


Step 1: How to Steps:

See my other two instructables for details on how to make this:

1. The AC Circuit Layout Version:


2. The AC-DC Circuit Layout Version, with a Diode Bridge:


Add triplets in series to get multiples of 3 for your light bulb !

Step 2: Work in Progress Photos

Made as many diode bridges and LED Triplets as possible for current and future projects.

Once made, it only takes two minutes to assemble a simple led bulb !

Connect them in series or in parallel, as per your comfort and experience.

Important Note:

Parallel is better, since if an led goes bad, only 3 will not light - so you can easily pinpoint which led needs to be changed.

In series, the entire bulb goes off, so you have to be best friends with the multimeter

Step 3: Final Results:

One with 18 LEDs (6 * an led triplet) and other one with 9 !

Step 4: Your Final Pics Please !

I have intentionally not put the final lighted pics !

Would love to see if people are actually making it and posting theirs !!

So waiting... ;-D

Step 5: Update - Final Pics

Ok ! So the lighted pics that many people wanted to see. I hope those who are proficient with AC Mains will make one.

Important Note & Disclaimer: DO NOT ATTEMPT, if you do not have sufficient knowledge & experience of working with AC Mains.

Tip 1:

U can use this simple wire connector concept even for ur 6V & 9V projects and avoid soldering (allergy)!
Now you can always make a project instead of just reading them! 

Tip 2:

Why are these "world's best" ?? Coz i used a single capacitor and single resistor and you can put 200 leds on it if you want!
Funny how no one disclosed it to you earlier! ;-DD

Tip 3:

They last a lifetime. I am using mine (and few frndz too at their place) since few years with 8-12 hrs of use per day. Only 3 are in series. Then the triplets are in parallel. So only 3 will fuse out, if one LED goes bad. Out of the 3, isolate & find out which one is bad and simply replace!! Decades of good lighting!

Tip 4:

You can encase the project in a pet bottle to avoid moths, insects, lizards. (I have intentionally not done so to check if it shorts, but its working fine).

    Ketan! Bless you! That kid just looks like me when i was that young.And I AM playing with lights since that age!
    Have a nice day! Do you have Yahoo/ SKype/ G Talk ID?

    Does it fully lightens your room. Plaese can you show step by step procedure. Parts Used And Rating of LED.

    Thanking You

    Sir i've already made a tube light of 30 led in series of 5mm LED. as guided by dipankar. But as it does not full lighting to the room thats why i asked help from you to please provide me with the drawing for making a powerful light with 1watt X ------- No. of LED or 3 watt X ------- No. of Led for providing sufficient light to the room.

    Thanking You

    Yours faithfully

    Add 30 more in parallel with the existing 30. Use additional capacitor and resistor for the new 30. Connect both capacitors in parallel. Similarly, both resistors.

    Clarification: Mr Dipankar's circuit is an AC circuit. It has mild flicker and he also clarifies it. I have used a diode bridge and made a DC circuit and so my circuit has no flicker (so it is brighter).

    My DC circuit (without flicker) : Part 2, as well as this I'Ble.

    Nice instructable,
    maybe you could provide the schemeatics of the Bulb.

    How did you calculate the necessary components ( LED / Diode / Capacitor ) ?

    "I have intentionally not put the final lighted pics!"

    But a lot of people like to see how well the final product performs before making it.

    "Challenge" has never been used anywhere - what was used was "Please" - to put things in perspective.

    Credibility is not being chased at all, i have made other I'bles & dont claim to be a master. I have learnt from this site...

    Your point about messing with AC mains is truly appreciated. Those who dont have sufficient knowledge should NOT attempt, period.

    thanks for ur views.
