DIY Home Made 6W LED Bulb

Introduction: DIY Home Made 6W LED Bulb

My objective with this project was to create a low cost energy saving LED bulb for slum areas. Energy saving bulbs are expensive here in Pakistan. Chinese bulbs rating 5 to 7 Watts costs around 6 to 8 US$ which are not affordable for lower middle class families.

So I started working on a LED bulb but the problem is I was not able to get housing for that so I started searching for housing, an old energy server's housing was enough for me but unfortunately I wont be able to find one for myself as shopkeepers in electronics market told me that only housings are not available you have to purchase complete energy saver.

So the to resolve first problem I was searching something so it can be used for wide production because I can make a bulb with any faulty energy saver or some old LED emergency light kind of stuff. 

Therefore I have decided to make the housing by myself, I have purchased one Adapter for bulb holder and one single switch plastic box for that purpose.

I cut the box from the back side and inserted the adapter into it, so it looks likes the energy saver housing. after that I have fixed the adapter via adhesive 




Step 1: LED Bulb Circuit

The circuit is consists of very few parts, just one resistor , two capacitors, four diodes and six high bright 1W LEDs. I have constructed circuit without any PCB. Just twisted components with each other and sold them to make the bulb work.

Step 2: Construct LED Bulb

After your circuit is ready, just sold LEDs over silver 6 LED plate in series, these plates are available in market easily. After soldering the LEDs to LED Plate (that uses as heat sink for LEDs). Now connect the terminals with circuit and screw the box.

That's it , your bulb is ready to light.

Step 3:

Just take care this circuit works with direct mains so there is huge risk of electric shock therefore avoid direct contact when testing it with mains. In one of the picture.

I have shown a picture  which is taken without any flash and bulb is producing enough light to light-up the room.

    what will be the output voltage across the C2.. DC voltage..

    Please can you help me out on this LED lamp circuit board. The resistor and the 100uF 50v capacitors are constantly burnt out after I replaced them

    What value of capacitance is appropriate for C 2 i use 10uf and d circuit is not coming on

    Hi! I want to replace a 40w florescent tube light in my kitchen with more or same amount of light as the tube rod from 220v AC. kindly enlighten my way.

    How nany costly this blub

    sir i have made this circuit but it is providing more than 400 v showing on multimeter which are too much for leds how can i reduce voltages? i have used 5.6 uf capaciter

    will this circuit work if i replace LEDs with 6w tube light?

    if not what changes has to be made????

    Can we think it will work for 2 years more or we can any other add in circuit advise us thx

    Hi
    No you don't need a step down transformer
    Thanks and best regards

    Realy it work with full bright ness?

    Is it work with 6 or10 1w led with full brightness perfectly?pls reply sir

    Sir whate is the out put curcuit current and voltage?1 w led need 350ma current.so is this capacitor sufficent for 1w led?because i know 155j cap produce less than 100ma current.pls sir reply me
