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
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.
great and learned something today. i too have four tubes with me i will try out

Dear,sir very use full to your led mecenisam but witch watts how many diodes use very use full to always thank you very much.
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.
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.

Excellent demonstration, keep it up and thank you. I would like to know if you could renew the defective LED's and rectify the fault. Regards Joseph
Thank you sir, very soon I will upload a video demonstrating how to replace individual LED in LED lights. Video shooting has already been done. By next week I will upload. Thanks for your compliments.
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.
r u sure?
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 .
Very nice explanation thanks 👍 I'm a new subscriber ❤

Mere tubelight me 4 led kharab thi wo bhi different locations par to unko todd kar solder iron se direct kar diya.. But ab mujhe diode lagana h to sari kharab led par lagau ya kisi ek led k point par??
Agar alag location pe 4 led kharab hain to aapko charo place pe diodes lagaane honge. But aise mein repair karna thik nahi hai dobaara kharaab ho jayegi. Poori tube nayi le lijiye.
Very informative video. 5 diode kue lagaiy hey? Shukeria.
Shukriya Janab, 5 diode lagaye hai. Kyonki jo char LED kharaab hue the oonke badle Series mein voltage drop dene ke liye. Nahi to baaki LED pe jyada voltage chale jaayenge aur tube fir se jaldi kharab ho jayegi.
सर जी मेरी ट्यूब लाइट 20 वॉट की एक साइड से लगभग 1 फुट काली हो गई है बाकी का हिस्सा जल रहा है इसके लिए मुझे क्या करना चाहिए
अंदर से क़ाली तो नहीं हुई होगी। तब आप उसे ओपन करके चेक कर सकते हैं। कुछ led fuse होंगे तो उसे बायपास कर लीजिये।

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
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
Good work sir

Sir ...यह tubelight कितने watt की है...
20 Watt ki hai sir ji syska ki.
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
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.
What is the rating of each LED in 20 watts tube light, also can u explain how to find the value of a LED.
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 kya iss tube light ki led bike ki 12v ki battery se chal sakti hai kya. Plzz reply hamare yha light ka bahut issue hota hai .
Sorry Vaibhav ji, ye 12 volt pe nahi chalegi, market mein 12 volt se chalne waali strip milti hain. Led bulb bhi milti hai 12 volt se chalne wali.
@@ShishuTechno Thankyou Brother for reply .
12v ki strip kitne tak me mil jati hai .
@@vaibhavverma8338 strip 50-100 mein mil jayega. Price Wattage pe depend karti hai. Agar bike ki battery se chalaani hai to 10-12 watt se jyada ka na len. Online v mil jaati hai. Strip v aur bulb bhi.
Diode by negative positive hota hai ya nahi
Diode mein positive negative hota hai. Oose anode cathode kaha jata hai. Ek bhi diode ulta laga to kaam nahi karega. Issi video mein maine bataya hai.
Agar LED late start ho rahi, aap bataiye kya problem ho sakti.2hrd let's hai full blow mein
Driver kharaab lag raha hai. Driver ka input and output electrolyte capacitor change karke dekhiye. Ya to driver hi change karke dekhiye.
If light is blinking ,new driver is required ?
If blinking is fast with sufficient brightness then probably the electrolytic capacitor (input side and/or output side) in driver circuit is faulty. Change the capacitor or replace the complete driver. Thanks for asking.
Good information
Thank you TECHNICIAN IDEA IN DWARKA🙂
Bhai agar direct shot kar diya jaye to isse LED light kharab ho sakta hai kya.??
Haan ji, short karke abhi to chal jayega, but doosre LED samay se pahle fuse ho jayenge.

My led tube same type - when starts it is lighting blow no problem. But after about 5 minutes start flicking. On off on off. It is disturbing. Having purchased for Rs.250.00 what is the use? If I bought same Rs.250.00 normal tube light Patti and tube set I would be able to change the tube as and when necessary. Please give solution for this on and off. Electric shop doesn't do this repair. Where can I get "diode"? It's price?
Flickering means probably some LEDs might be faulty. First identify the faulty LEDs then bypass it with diodes. Diodes are easily available at electronic spare shops. Price is maximum 1/- per piece. Sometimes driver capacitor may also be faulty.
I like your video good job bro

Hi, If suppose one Led (nearly 13 no & 40 & 60) is not working then (13 no & 40 & 60) where have to solder diode? Pls. Inform
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 But light is not glow , now I have to chk. Driver

अलग-अलग वाट के एसएमडी प्लेट में एसएमडी खराब हो जाने पर कितने वाट के एसएमडी के जगा पर कितने कितने नंबर का रजिस्टेंस यूज करें
1 watt ke liye 68 to 82 ohm
2 watts ke liye 47 ohm to 68 ohm.
Hamesha pahle jyada ohm ko try karen. Agar sahi na lage to kum ohm se try karen. Resistor mota wala 2 watt wala use Karen.
If you do no supply power and change multi meter to diode/continuity mode placing probes on each led terminals would make working LED glow and not the burned ones!!
Nice analysis, these LED are different from those used in indicators. These LEDS are of higher voltage and higher current ratings and since each 4 diodes are connected in parallel, so would be difficult to glow these by multimeter probes, I will check once again and will update. Though checking of LEDs as diode with multimeter will definitely work.

Sir Siris negative postive negetive postive ase logane chanhia na ?
Yes sir bilkul aise hi.
Excellent
Can same process working for 18 watt ac led bulb.
Yes it will work for an LED bulb too.
You can use 4.7 Ohm resistor to get the desired voltage drop instead of 1N 4007...
Good analysis, in 20 Watt tube we can use 4.7 E resistor in place of each diode. Resistance will come cheaper too. But ideally resistance will consume more power than diodes. Now a days resistance are normally not used for controlling the current or power, except biasing circuits and indicators. Though resistance will work well.
@@ShishuTechno you mentioned that we should use 4.7 E resistance for each diode, this means total 4 resistors we suppose to use? If this is the case, can we use just 1 (one) equivalent resistor? (like one 25-E resistor). Thanks for making very useful clip & please keep on making more such useful videos.
Five resistances in series in place of five diodes atleast 1 watt each
Bina diode short nahi kar sakthe kya
Bina diode ke short karenge to bhi tube glow kar jaayegi. But pahle se fuse hue LEDs ka voltage drop ka load baki achhe Wale LEDs pe cahala jayega aur fir dusre LEDs jaldi kharaab ho jayenge. Diode lagaaye jaate hain ootna voltage drop provide karne ke liye.

Sir I am in need of smd LED in huge quantity for 5w to 15w LED bulbs and 18w to 28w and for tube lights, I am the dealer and distributer of all led items since 7 years, can u reply me immediately
Sir don't do components business, so I don't have such references.
If 1 led is not working then how many diode to be used.
Check the voltage across the faulty LED and then connect the number of diodes by dividing that voltage by 0.7 (approx) . If your case is of a tubelight then probably other LEDs of that particular group will be blown off in a few days. Then apply 4-5 diodes for that particular group of LEDs.
