How to repair LED tube light | Easy method

#howtorepairLEDtube #LEDtube #LEDtuberepair
Don't throw your old faulty LED. It can easily be repaired. Correct method will prolong the life of your faulty LED tube.
Don't directly bypass any LED, instead use appropriate diodes for required voltage drop.

Diode ki rating kaise decide kare Bahut badhiya

[@ShishuTechno]

50 watt tube tak yehi diode kaam karega 4007 wala. 50 watt se ooper or 100 watt se niche ke liye 5408 lagega jo ki amooman use nahi hota hai.

[@ezequielsanuy8895]

You can cancel with a single wire and the electronic supply auto adjust down the voltage for the remaining LEDs in the row. Because it senses mili amps and when it reaches the amp the switching supply cut the current, so the less LEDs in the row the faster the supply switches... And the voltage is correct for the remaining number of LEDs.

[@iotrnd2384]

r u sure?

[@mukeshshah2704]

Not necessarily SMPS will lower the voltage. In fect adding few more diodes will add life of remaining LEDs. If set of 5 to 7 LED can be soldered than it will work well .

[@rsubram24]

Çan we use zener diode?

[@ShishuTechno]

Nope! Zener diode will not work for long time. It will not tolerate heat produced and it will burn in few seconds.

Sir mujhe ek doubt tha. Mere pas 9watt ka AC bulb hai toh AC bulb AC current ko dC mein convert karke hi led jalate hai kya. Mujhe agar damaged led ko replace karna hai toh kya mein uski place par DC 1 watt led laga sakta hu kya, ya fir 1 watt AC led lagani padegi

[@ShishuTechno]

Namaskar Sabhi LED lighting ultimately DC pe hi work karte hain. Ek driver circuit se AC ko DC me convert karte hai. Damaged LED ko same type ke led se replace karna padta hai. Agar LED na mile to resistance ya diode se faulty led ko bypass kar sakte hain

#ShishuTechno If circuit is damage then which kind of circuit to be fix. Because there in market same circuit is not available. Pls suggest

[@ShishuTechno]

It is a difficult situation, yet we can try following.Try to find any 20 watt faulty tube, use driver circuit of that. In second method we can try this take one diode 1 N 5408, one 40 watt or 60 watt incandescent bulb in series. Connect this series combination to the led strip. Connect the diode with appropriate polarity. I think tube should glow but I am not sure. Flickering may also be observed. If a bridge is used in place of single diode then flickering will be less.

[@RoufAbdur-bu4cc]

@@ShishuTechno Already try this method. 3/4 days is glowing ok but after 3/4 days 20/30w driver also damaged. Now what to do?

Sir, nice video but one question in this video . Diode ki rating kese Messer kari ? How to use 5 diode 4007 ? Plz proper explanation Sir.

[@ShishuTechno]

कितने डायोड लगेंगे इसके लिए हमें दो चीजें पता होनी चाहिए . 1. इसमें LED स्ट्रिप पर ड्राइवर की सप्लाई कितनी आ रही है. 2. पूरी एलइडी स्ट्रिप में कितनी एलईडी किस तरह लगी हुई है. मेरे वाले ट्यूब में ड्राइवर से 80-90 वोल्ट सप्लाई आ रही है. और टोटल 96 एलईडी लगे हुए हैं. चार चार एलईडी को parallel में एक ग्रुप बनाकर 24 ग्रुप सीरीज में लगाए हुए हैं. इसलिए चार एलईडी का जो एक ग्रुप है उस पर लगभग 3.5 वोल्ट आता है (80volt/24). मतलब चार एलईडी का जो एक ग्रुप है वह लगभग 3.5 वोल्ट का ड्रॉप देता है. अब मान लीजिए कि चार parallel एलईडी का कोई एक ग्रुप है जिसमें एक एलईडी फ्यूज हो जाता है तो उसका लोड उसी ग्रुप के बाकी तीन एलईडी पर चला जाएगा और वे तीनों एलईडी एक-एक करके तुरंत ही फ्यूज हो जाएंगे. इसीलिए एलईडी ट्यूब में हमेशा एलईडी ग्रुप में फ्यूज होते हैं. क्योंकि उस ग्रुप के सभी एलईडी parallel में होते हैं इसलिए किसी भी एक एलईडी को शार्ट कर देने से पूरी ट्यूब ऑन हो जाएगी. लेकिन उस ग्रुप का वोल्टेज ड्रॉप मिस हो जाएगा. और वह बाकी एलईडी को ओवरलोड कर देगा. इसलिए उस ग्रुप के बराबर वोल्टेज ड्रॉप देने के लिए हमें डायोड सीरीज में लगाने पड़ते हैं. एक सिलीकान डायोड 0.7 वोल्ट का ड्रॉप देता है तो 5 डायोड 3.5 वोल्ट का ड्रॉप देगा. डायोड 4007 को इसलिए चुना क्योंकि यह 1000 वोल्ट 1 एंपियर तक काम करता है जो कि यहां पर सूटेबल है। सीरीज डायोड के इस कंबीनेशन को फ्यूज हुए एलईडी में से किसी एक एलईडी के parallel में लगा दीजिए.

If only those three LEDs are not glowing and the rest all are glowing full intensity, then we can leave the light as it is. But if rest of LEDs are glowing dimm then bypass each LEDs with diodes. . May check and please update here for further knowledge sharing.

[@ShishuTechno]

Different types of LEDs are used in different versions of tbe/bulbs. But commonly used LED type is SMD LED 2835 , maximum wattage 0.5 W. But circuit is designed in such a way that it gets about 0.3 Watt per LED to enhance its working life.

Sir Apne 5 diode lagaye kyuki apki 5 led kharab thi agar humare 1-2 ya 3 led kharab ho to bhi 5 diode hi lagane hei kya

[@ShishuTechno]

iske liye aapke tube ki led strip ko samjhna hoga. pata kariye ki kitne LEDs ki grouping ki hui hai. agar kisi group mein 1 led kharab hoga to baad mein dhire dhire aur led bhi kaharab ho jayenge. isilye ek particular group ko bypass karna padega. Normally 5 diode se ho jayega. mere case mein 4 led ki grouping ki hui thi, inko 5 diode se bypaas kiya tha.

Yes replacing the LEDs with new spare LEDs is the best way to repair the tube. But if the fault occurs frequently then it is better to replace the complete tubelight with a new one. Coz all equipments have limited operational life.
