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

Now solder the bridge rectifier to the circuit board from where you have removed
the filament joining capacitor
Step 6: Connection Wires

(http://cdn.instructables.com/FWL/IW9G/H5IRUQYR/FWLIW9GH5IRUQYR.LARGE.jpg)
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
(http://cdn.instructables.com/F0C/TLQ8/H5ECN4NV/F0CTLQ8H5ECN4NV.LARGE.jpg)
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
(http://cdn.instructables.com/F11/PL0E/H5IRUQXL/F11PL0EH5IRUQXL.LARGE.jpg)
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

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 correctcapacitor. 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 capacitorand this is what i am using at the o/p ofbridge rectifier... But i am not sure
whether the whole circuit is workingfine or not, as initially when i switch it
on the o/p voltage is 110 V dc then itfalls down gradually to 50-60 V dc. Iam totally stuck now....
Manendraks5 (/member/Manendraks5/)
Hi can any one please tell why I am getting very low o/p load current i.e. in 0.2 to 0.6mA.
1- I am using a 20W CFL rated 100mA which is giving o/p voltage of 50 to 60 V DCafter 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....

uf4007 is not available in multan. what should i do?
ramizsattar (/member/ramizsattar/) (author)
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 fromthere.

how many 1 watt LEDS?
ramizsattar (/member/ramizsattar/) (author)
AOA
One 5 mm LED takes 20 mA current and it is 3.3v so 30 LEDs in a string tocompensate 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 wattLED.
mhqh77 (/member/mhqh77/)
Asslamoalikum, please let me know how many 5mm LEDs can be use in the aboveproject in 30 strings...
waqasOO9 (/member/waqasOO9/)
AoAgreat 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 eachI have also changed the value of capacitor 0.1uf, 0.15uf, 0.25uf 400v18w energy saver label says 135mA current
any idea what Im doing wrong ........... ?

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 hopeso).

Hello,
My question was can we measure off load voltage getting at o/p after rectificationdone? Because when I try to measure off load voltage, 12 ohm register used in this
circuit immediately blow off. please reply. Regards, Jayesh
MazharKhan (/member/MazharKhan/)
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 howmany 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 [email protected].
Respect & regards,

Assalam o AlaikumSorry for the delayed answer.Thank you for your nice words.
Well the capacitor I removed is acoupling capacitor (you can say) and
it actually connects two filaments ofenergy saver bulb and that is theoutput of that all circuit. So I removed
that capacitor and added a bridgerectifier I want to get DC output fromhere. The other capacitor is a filter
capacitor which actually filters theoutput DC voltage. You can
experiment with 0.2uf 0.3uf 0.47ufand 1uf above or equal to 400V.I got 0.5 watt LED which takes about
150mA current (try to use 140mA itincreases the life of LED) the output
current of 23 to 15 watt energy saveris almost 140 mA DC (aftermodification). the current of 8 watt or
11 watt is almost 50 to 70 mA DC.Now you have to choose the LEDwith the same current. You can
experiment with 8 or 11 watt butplease keep in mind the output
current.I have used 45 watt energy saver forthe same. it actually uses 750 mA
current when used as energy saver,but after conversion it only produces
270mA DC current. 270mA currentmeans the circuit will produce 0.270AX 100V = 27 watts. In this circuit I
used 1 watt LEDs which consumes300 mA current so my LED can worklonger on 270mA.

current from a source which has lesscurrent than the desired, the voltagealso play an important role, say if you
have 12 v and 500 mA then roughlyyou can increase the current to 800
mA by sacrificing voltage till 5 to 6volts (voltage drop), here you will usea boost topology for increasing
current (mostly used in switchingpower supplies). You can try boost
circuits (lots of available on internet)check their electrical specificationsfor your desired current and voltage.
When you try to boost the voltagethere you sacrifice current. Voltagedoubler circuit can be achieved by
using diodes. Thanks.

You also need to mount this type of LED (3 watt) on heatsink otherwise after
heating it will go out.

Hello dear I have used this technique and circuit for many conversions and they all worked on the
first go. I have used good quality LEDs all 0.5 watt. There may be an issue of LED current, if you check your LEDs for equal current then I
hope this issue will be solved, may be your LEDs are of different current rating. Themethod is to check is using a circuit (use LM317 in current control mode seecomments by other people) which will produce 150mA current (use a 6 or 9 volt
battery) and LEDs for the light. All LEDs must produce equal light with same color youmay need to check all 30 LEDs,
I always get LEDs from market after checking them on the spot because these LEDsavailable in the market are rejected lots from china which these market people bringand no one knows (even shop keeper) how to check them for best performance. You
need to do it yourself. try internet for LM317 for current mode (using 8.2 ohm 3 watt resistor) you will get lotof circuits on internet.

fused.Can i used 1 watt leds same as in that cct like half means 15leds .i use in mycct 23watt saver & its o/p current is 75DCV i dont know how amperes in it? Sir now
tell me hows the cct working or can i use 220n 400v capacitor & uf4004 ?? sir i live inkarachi pakistan at landhi. regards

Dear read my project post again andtake your time to read it.
Circuit will produce almost 100v DC,LEDs you are using are of 3.3v a 25wCCF will produce almost 130 to 140
mA current. you should use at least 28LEDs in series to reach that 100v. 12
LEDs means 12 x 3.3v = 39.6v thatswhy LEDs burnt. 0.5 watt LEDs will workand should produce light equal to 11
watt light. If you are living in Karachiplease go to Tariq Road you will find
you components there. REMEMBER THIS IS A HIGHVOLTAGE AND HIGH FREQUENCY
CIRCUIT YOU SHOULD NOT TOUCHLIVE CIRCUIT.

capacitor but not less. Also 220n canbe used. Use 23 watt or 25 wattenergy saver. Do not use less than
this current will be reduced. Also usehalf watt LEDs not one watt. Be
careful its high voltage circuit. ENJOY. do you live in Lahore Pakistan if yes
then go to hall road and get therequired capacitor.
