For larger rooms , 2 or more tube light can be fitted. "How much mercury is in fluorescent bulbs? If you observe any deformed/burnt capacitor/diode/resistor, de-solder and remove it out of PCB and carry out the replacement with a newer component of same value or replace it with best possible alternate with a voltage rating of at least or above 250 volts. It is also known as compact fluorescent light, energy-saving light, and compact fluorescent tube. Compared to general-service incandescent lamps giving the same amount of visible light, CFLs use one-fifth to one-third the electric power, and last eight to fifteen times longer. CFL converted into LED lamp. Check your repaired CFL. Simple Circuit. I have lcd monitor with inverter problem. Compact fluorescent lamp normally fails because of damage to some of its components like transistor, capacitor, diode, resistor or even the transformer. They might actually think they got smarter.). Like all fluorescent lamps, CFLs contain mercury, which complicates their disposal. I used to regularly repair CFLs, before I switched to LED lamps. How can we find what is voltage atviutput terminal?can we use is to make led bulb ? How to Convert CFL into LED Bulb. other side has two pair of wires 9four wires) these will be connected to the replacement type 20 Watt 24" Florescent Light bulb. Capacitor C2 is also discharged (after charged to its full value) each time the transistor Q2 operates. Drive voltage may be according to your country 110 Volt or 220 Volts. Great !dea .... but for me i make use of burned out CFL by using its top as adapter for bulb holder. My mom also said this. how to get free electronics out this dead  "Compact fluorescent lamp" there is so many electronics in there  Lorem ipsum dolor sit amet, consectetur adipiscing elit.Morbi adipiscing gravdio, sit amet suscipit risus ultrices eu.Fusce viverra neque at purus laoreet consequa.Vivamus vulputate posuere nisl quis consequat. The only risk is if you break the bulb. Just don't break the bulb. It means the circuit of most of the discarded CFL units never goes faulty, and can be recycled through some other means. A compact fluorescent lamp (CFL), also called compact fluorescent light, energy-saving light, and compact fluorescent tube, is a fluorescent lamp designed to replace an incandescent lamp; some types fit into light fixtures formerly used for incandescent lamps. It has been used clinically, but because of its toxicity this use is diminishing. Did you make this project? It will disperse the mercury into the air and increase exposure to it. This could be why most asian children do so much better in school - they eat about 1000 times more fish than we do. Ratna is a B.E (Computer Science) and has work experience in UK Mainframe IT industry. In my experience these CFL ballasts accept wide range of lamps with light output variation. Now after assembling check all connections taking care there should be no loose connection. Mercury is also used as a preservative in vaccines. My mother doesn't want me to do this because she is worried about the mercury in the lightbulbs. Immediately after this process, the second transistor is excited by reverse winding of TR1 and so the process goes on. Carefully remove the broken glasses. This post will discuss about how to easily re-utilize your damaged CFL with step by step method explanation. DO NOT OPEN THOSE CFLs WHICH HAVE BEEN USED WITHIN TWO HOURS. It will conduct if forward biased and will not conduct if reverse biased. LEDs have very long life. on Introduction, Reply ", "About 60 percent of all fluorescent lamps sold in the U.S. in 2004 contained 10 mg of mercury or less. She is an author, editor and core partner at Electricalfundablog. Strange how that works. Reply on Step 3. as long as the glass doesn't break you should be ok. If the glass tube is damaged, then also you can change it. The transistors used in the circuit may reveal actual wattage. Reply 3 years ago. hi. For a layman this might look pretty tough....but actually it's quite easy. It doesn't make sense to me to be so cautious about one toxin but then so cavalier about another. Check the transistors. I found CFLs are bad for lighting house. The CFL also consists a switched mode converter. This results in stepping down of the voltage. The greatest threat comes from the inhalation of the gas which is released at the time the tube breaks. You will see four points (solder) for each of the lamp side. A CFL uses vacuum pipe which is principle wise same to the strip lamps (commonly known as Tube light) . If you have learnt anything from it, share this post with your friends and save their money. CAUTIONARY NOTE : DO NOT OPEN THOSE CFLs WHICH HAVE BEEN USED WITHIN TWO HOURS. Never again will I dispose of a CFL without recycling its electronics.

Under regular running condition, if the transistor comes in OPEN state, The current being fed to TR1 keeps increasing till the core of transformer saturates, and thus the feed to base drops down resulting it to close the transistor. You have to keep the following terminology in mind : The Diac, C2 and R6 send a voltage pulse to Q2 Transistor’s base which causes it to get its threshold value and it starts operating. It is only slowly absorbed through the skin, although it may cause skin and eye irritation. Be careful not to break the bulb. Repack the cap on the Tube. I remember riding my bicycle down a huge stairway and continuing on the concrete road below for the next grew get until I get to the home made ramp that I used to jump my bike on.....all without a helmet. Therefore after its first start, There is not enough energy left for reopening of Diac. If the cap is bulging, don't use it. Avoid licking, chewing or swallowing the glass. Should be fine. Seetharaman’s words about the circuit: I am sending you a table lamp made from defunct energy saver lamp with broken tubes. Inside the base of the CFL are a whole bunch of electronics parts which you can discard or reuse for something else. The only part of the CFL you need is the spiral fluorescent tube and the wires that are connected to it. Cutting open (or gutting) the Compact Fluorescent Light (CFL) The only part of the CFL you need is the spiral fluorescent tube and the wires that are connected to it. Some time wattage are written fictitious. The CFL PCB is quite compact and fits in the holder base. In many countries, governments have established recycling schemes for CFLs and glass generally. You should be fine if you take these simple precautions. She is also an active Web Designer. You will need a replacement type Florescent Light bulb of 18 or 20 Watts type and hardware to hold the tube bulb and ofcourse salvaged electronic module from the CFL. These accelerated electrons strike Mercury and Argon atoms which in turn results in the arise of a low temperature plasma. Thank you in advance. The CFL was initially designed to replace the incandescent lamp in terms of its compactness as well as energy efficiency. This tube is fed with AC power supply which facilitate the changing functionality of Anode and Cathode. 3 years ago, you can use upto 65 w cfl or pl circuit for 40 w tube only .... for bright light than 40w, Reply Take out the lamp and do the cleaning of circuit using alcohol. This post will discuss about What is CFL, How it works, Phase wise Circuit Explanation, Advantages and Disadvantages. Reply The most common rate is: Open the cap of CFL. Reply Actually, you get more mercury exposure by eating a tuna sandwich than by breaking the bulb. Cathode is having a temperature of about 900º C and generates a beam of electrons which is further accelerated by potential difference between electrodes. on Introduction. The reuse/ repairing of damaged CFL is quite easy. This requires a bit of patience and alertness as some bulbs are difficult to disassemble and it is hazardous if you break the glass. I know your orginal comment was two years ago but I just read it. About: thank you sunshiine for supporting me : ) i am mahmoud , i live in Egypt , i like to inventing new things form junk and old toys and, Inchworm Robot - Modular, Move Allsides With BT App, 3D Printed Arduino Powered Quadruped Robot. After separating the ballast, closely observe the circuit. CFL circuit of 18-24 Watts are useful for the activation ofreplacement type two feet 18-20 Watt Florescent Tube Light bulb. Replace it if an open circuit is observed. anyone else reuse ballast board from busted cfl? How safe is this to do and is there a any risk of mercury exposure? have you tested those boards, can it be used as a led/led strip driver?what voltage does it put out? Maybe that's why I am the only one around that knows the difference between "they're, their and there" and "you're and your" etc. It is a normal practice around the world to throw the damaged CFL and purchase a new one. you can do this without breaking the tube and if so then there is no risk of exposure to mercury. LEDs and florescent are not in the slightest similar. Few components available in the CFL PCB also can be used. If you are not able to do it, then go to an electrician and say him to check/replace it. 5 years ago Lost your password? The circuit of CFL is explained in succeeding paragraphs. This requires a bit of patience and alertness as some bulbs are difficult to disassemble and it is hazardous if you break the glass.
