Introduction: Using Energy Saver Light Circuit for LEDs (An Improved Energy Saver Light Hacked From CFL Circuit)

DANGER HIGH VOLTAGE
 

I am using this idea since last six months, it just came in my mind (why not experiment).
You need the circuit of an energy saver bulb whose tube is burnt or damaged.
 
This is a high voltage and high frequency generating circuit, be careful there is high voltage present if you connect it to AC line. There is a high voltage input capacitor (from 2.2uf to 10uf 400 volts). The idea is to put a bridge rectifier on the output on this circuit and use for LEDs.
A 23 to 25 watt energy saver’s output can produce 165 mA current (it is written on it) for the energy saver light bulb. We need to use this constant current output for our LED lights. By using bridge rectifier (ultra fast)  you can get 100 volts of DC. A high frequency switching output cannot be rectified properly by using normal bridge rectifier like 1N4007 or similar. We need an ultrafast diode to make a bridge rectifier like UF4007,BYV26 or similar.

Step 1: Open Energy Saver Bulb and Remove Its Tube

Open energy saver bulb and carefully remove its burnt tube from the top. Be careful its glass tube.

Step 2: Filament Connections

Identify filament connections and joining capacitor.
See where filaments of the energy saver bulbs are connected.

Step 3: Short the Filament Points

Short the filament points using soldering iron

Short filament 1 connections together
Short filament 2 connections together
Remove filament joining capacitor

Step 4: Bridge Rectifier

Make bridge rectifier and add capacitor on the output
You need a ultra fast switching diode uf4007 or similar and 0.1uf 400v capacitor

Step 5: Add BR on the Circuit Board

Now solder the bridge rectifier to the circuit board from where you have  removed the filament joining capacitor

Step 6: Connection Wires

Now add connection wires to the output of the BR +ve and -ve
Here you will get about 100V DC and 130 mA current

Step 7: Make a Series of LEDs

A 0.5 watt at 3.3v LED consumes 150mA current so it is safe to make a series of 30 LEDs. You can use small LEDs of 20 mA current in multiple strings till the output current and voltage matches (30 LEDs in each string)
LEDs can be assembled on a heat sink insulated material or if using 20mA LEDs then on PCB. When circuit is ON Do not touch the LEDs or any area of circuit as there are high voltage present . I have used 23 to 25 watt energy saver circuits. There are 45 watt and 85 watt circuits available which can produce more current (a one watt of energy saver bulb will consume 7.2 mA current so 45 watt can produce 100V and 320mA). In this way 1 Watt LEDs can be used. Following light is consuming 230V at 53mA input and producing 12.5 watt light.

Step 8: Complete Light

Here is complete light it is rated 12.5 watt. At the AC 230v input it is consuming 53 mA current.

Step 9: Other Big Light Using Two Energy Saver Circuits

Hello dear!
Sorry I was not checking my e-mails due to some problem.
Yes we can measure the output voltage with and without load.
Can you please let me know where you placed that resistor.
We can directly measure that voltage without any resistor directly with DVM.
Please check the selector of your DVM it looks like it is on Current selection. (I hope so).

Aslam.o.Alikm Ramiz Bhai
I like it, but I have a few questions regarding to this system.
please guide me about these points.
1. Why we are using LEDs instead of fluorescent bulb(rod)? As a new fluorescent bulb(rod) is available in market just for 40/-PKR.
2. If we use LEDs as u describe, then that circuit will use less current/energy or same as was using before with fluorescent bulb(rod). Means circuit was of 23 watt, then how much it will consume energy after attaching led, instead of fluorescent bulb(rod)? 23 watt?
3. Is the light/lumens of LEDs with this circuit will be more or same as before with fluorescent bulb?
Waiting for your reply.
Allah Hafiz :)

Hello! Greats instruction! I tested with 60 led string 150mA but it's doesn't work, maybe is the input 120v 60hz, what do I need to change in your opinion ?

author
ramizsattar made it!(author)2015-01-29

Well dear you need to change number of LEDs I hope you know how to measure voltage across the two ends of LEDs string. I think you missed some points in my instructable please read it again. Due to the 120v may be you are getting less volts.
For example If there are 60 volts output then you need
60/3.3 =18 LEDs.

Please also note the voltage and current rating of the LED as they will get damaged if more voltage is given to them as the current will also increase and LED will get damage. Also it will produce lot of heat.

author
ramizsattar made it!(author)2014-11-24

Please note that energy saver can not produce current in Amp.
The experiment which I did was only in mA. (150mA)
You need a proper LED driver for getting large current in Amps.

I actually used the voltage (100 volts) for a string of LEDs.

You can get a good switching power supply of 5A 12V from the market as they really and exactly produce the power you need. Then use it for your purpose. Thank you.

May be the circuit you are using is it not working or damaged.
Also read the procedure again and check that you are removing the correct capacitor. Also check there should be a filter capacitor (0.1uf - 0.47uf) on the output of bridge rectifier (UF4007).

I guess the capacitor image i've uploaded below is a filter capacitor and this is what i am using at the o/p of bridge rectifier... But i am not sure whether the whole circuit is working fine or not, as initially when i switch it on the o/p voltage is 110 V dc then it falls down gradually to 50-60 V dc. I am totally stuck now....

Hi can any one please tell why I am getting very low o/p load current i.e. in 0.2 to 0.6 mA.
1- I am using a 20W CFL rated 100mA which is giving o/p voltage of 50 to 60 V DC after modification but very very less current i dont know why?

2- For bridge rectifier i am using UF4007 diode and below shown capacitor.

3- Connected 20 - 1 W Leds in series

Someone please guide....

Try UF4007 (this is ultra fast diode) or BYV26. DONOT use 1N4007.

If you can get a hyper fast diode (in 1A rating) that will be super.

Where do you live? If you live in Lahore go to Hall Road you can get this diod from there.

AOA

One 5 mm LED takes 20 mA current and it is 3.3v so 30 LEDs in a string to compensate 100 volts and depending on the current the number of strings will be 7 (if 140 mA current).

I will recommend not to use 5 mm LEDs I have already did it but the result was not good the heat produced reduced the light its always better to use 0.5 watt or 1 watt LED.

great diy ..... why does the diode gets extremely hot, I have used the 3amp and 5amp diodes also, still they get very hot

it gives current about 100mA DC
30 led in series 150mA each
I have also changed the value of capacitor 0.1uf, 0.15uf, 0.25uf 400v
18w energy saver label says 135mA current

any idea what Im doing wrong ........... ?

Assalam o Alaikum Ramiz Bhai,

No doubt that was a great experiment you did.

First why did you removed the actual capacitor from the circuit and put the other one...???

Second... Please let me know;
if I am using 8w or 12w energy savers, which kind of capacitor should I use and how many LED's would be enough.

I would be lucky to learn more from a knowledgeable person like you and will be grateful for your reply at my e-mail address freakned4u@yahoo.com.

Respect & regards,

Mazhar Khan

Assalam o Alaikum
Sorry for the delayed answer.
Thank you for your nice words.
Well the capacitor I removed is a coupling capacitor (you can say) and it actually connects two filaments of energy saver bulb and that is the output of that all circuit. So I removed that capacitor and added a bridge rectifier I want to get DC output from here. The other capacitor is a filter capacitor which actually filters the output DC voltage. You can experiment with 0.2uf 0.3uf 0.47uf and 1uf above or equal to 400V.
I got 0.5 watt LED which takes about 150mA current (try to use 140mA it increases the life of LED) the output current of 23 to 15 watt energy saver is almost 140 mA DC (after modification). the current of 8 watt or 11 watt is almost 50 to 70 mA DC. Now you have to choose the LED with the same current. You can experiment with 8 or 11 watt but please keep in mind the output current.
I have used 45 watt energy saver for the same. it actually uses 750 mA current when used as energy saver, but after conversion it only produces 270mA DC current. 270mA current means the circuit will produce 0.270A X 100V = 27 watts. In this circuit I used 1 watt LEDs which consumes 300 mA current so my LED can work longer on 270mA.

Hello Dear,
I am thankful to you for the nice comments.
You have not mentioned the supply voltage.
I will give you a general overview about it. When you go for increase in current from a source which has less current than the desired, the voltage also play an important role, say if you have 12 v and 500 mA then roughly you can increase the current to 800 mA by sacrificing voltage till 5 to 6 volts (voltage drop), here you will use a boost topology for increasing current (mostly used in switching power supplies). You can try boost circuits (lots of available on internet) check their electrical specifications for your desired current and voltage.
When you try to boost the voltage there you sacrifice current. Voltage doubler circuit can be achieved by using diodes. Thanks.
