Mains Operated 25nos. Led Lamp

Intro: Mains Operated 25nos. Led Lamp

Hi



This is a 25 nos Led  operated from mains of 230v supply. I bought a flourscent lamp adapter from a scrap dealer, because its easy to dismantle (a screw in the middle of the fitting) instead of cutting etc.,.the beautiful thing is, in many homes we find damaged, burnt out CFL, adapters etc., where we actually have no use, hence with few components readily available in the market and a hour on a sunday afternoon, you should be able to put these components together.

STEP 1: Circuit Diagram

Circuit diagram to that would make your work easier

STEP 2: Components Required

Components that you would require for this project:
-1 no. Polyester Capacitor 0.22mfd 400v
-1 no. 1M 0.25 watt resistor.
-1 no. 22 ohms 0.5 watt resistor
-4 nos. Diode 1N4007
-25 nos. LED white colour 5mm.
-Small perforated board for fixing the components on to it and that which would fit your CFL enclosure.
-2 mm PVC sheet cut in round that it would fit to the size of your CFL.
-Any CFL bulb or Adapter for this project. (CFL adapter is shown in the photo below) its is easy to dismantle the screw/fastener in the middle of the CFL)
-some wire for soldering.

Tools that you would require for this project.
-Drilling machine with 5mm drill
-Jigsaw for blade for trimming the perforated board and PVC sheet.
-Sand paper for smotthing the edges.
-Flat screw driver if your using a CFL adapter

STEP 3: Dismantling the CFL Enclosure

The Screw/fastener in the middle of the CFL to be removed with the help of a screw driver for removing the existing pcb and top cover.

STEP 4: Fitting of Leds on the PVC Sheet

Cut the PVC sheet using a Jig saw that it matches with the enclosure and drill 25 nos. 5mm holes on the PVC sheet using drilling machine to your choice and pattern. just slide the LEDs and solder + to _ in series

STEP 5: Solder Components to Perforated Board

Solder the components on to the perforated board and the two wires protruding from within the CFL (AC mains wires) to be soldered to the Perforated board to the AC junction 

The other two wires to be soldred to the positive and negative terminals from the diode to the led positive and negative points.

Once the components are soldered and the wire in place, put back the everything and witha little quick fix, few drops on eithe side to put the top cove in place and your project is ready for checking.

STEP 6: Testing

Take a socket with two wires connected to the socket and fix your led project into this socket as shown,
plug the two wires into AC OUTLET OF 230 volts, if you have wired as per instructions, then your LED project should light up.

STEP 7: LED Light at Night

All the best.

Thank you very much
Thank you very much, I was looking for something like this, only two questions, drawing on the resistance of 22 ohms at 1 watt and then on the necessary components to 0.5watt says,,,, is the same?

I have a LED, 5mm I 20mA - 30mA, U 3.2-3.35volt
I can use with this circuit?
Thank you very much!

pd English translator of google.
A condenser of 4.7mFd/250V after the diode bridge would enhance the light making it flickerless !

Sir, using 25 leds the light is little bit low,So i want to do light bulb using 50, 75 and 100LED

Please tell me circuit diagram for 50led, 75led, and 100led .
Is it possible to do with same circuit with miner changes?My mail id =akshayjadhav9610@gmail.com

Hi,
Very nice project! Can you tell me please what is the purpose of the capacitor in this circuit? Thanks,
James
Hello Friends,
Just to share with you, this LED Lamp has been working for the last 3 years and still going... good.. cheers
I used the same procedure and build the led it worked first.But after some time some led did not glow what are the reason and how to overcome that

Sir I followed all the above procedure and made led to glow .But first all led glows, after some time some led didn't glow what is the reason and how to over come it

very helpful project for us..

plz specify the specifications like wattage, power ratting, lifespan, power saving of this bulb as compared to ordinary bulb units per volts etc of the bulb...at my email id appoogandi@gmail.com

thanks..

can i use 15no 3v leds in same components as you use

How to make SMD led solder

This is very nice project,i done this.
