Yes .v r expecting ur another vidio sir.

@@alagappansockalingam8699 thank you sir.

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.

Thanks sir for appreciating us.

Thank you very much

Yes agree👍

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 .

Thanks a lot.

Thank you sir for motivating us.

Welcome my friend, Thank you very much🥰

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.

Ok sir, noted for upcoming video.

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.

@@ShishuTechno ok

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।

Thank you akshay ji

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

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.

@@ShishuTechno 👍

kk

Gandu he checked the diodes with an insulated prove not with Multimeter.

Thank you Venu G.

Thanks Sharukh Bhai.

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, my led tube light intially glowing dim, after 5 minutes glowing brightely ... What is the problem and what I can do ..?

@@tulugusivakumar3510 ji your led driver (power supply ) may be faulty, mostly filter capacitor in case of smps type. or pf capacitor in case of pf driver type.

Thank you chandan digital.

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.

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.

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

Thank you sir for watching and your compliments 🙂

धन्यवाद रंजन जी पूछने के लिए। मैं एक वर्किंग इंजीनियरिंग प्रोफेशनल हूं। मुझे समय थोड़ा कम ही मिल पाता है। पर आपने पूछा है तो मैं जल्द ही एक ऐसी ही कोर्स इसी चैनल पर स्टार्ट करूँगा।

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

Amazon pe mil jayega, search kar ke dekhiye SCSS insulated Forceps tweezers price approx 195/- Alis insulated forceps tweezers price approx 199/- Link nahi de pa raha hoon reason ye video trending type hai, video ka metadata disturb na ho isiliye.

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.

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

20 Watt ki hai sir ji syska ki.

Driver kharaab lag raha hai. Driver ka input and output electrolyte capacitor change karke dekhiye. Ya to driver hi change karke dekhiye.

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.

धनयवाद मनोज जी.🙏

Thank you Dada!

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.

Sure👍

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.

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.

Thank you sir

Thanks Kosein 😊

Yes it will work for an LED bulb too.

Thanks for watching 🙏

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.

@@ShishuTechno : Thanks for clarifying... Great

Actually wo capacitors nahi balki diodes hain. Short karke v chal jata, but kuchh local company ke tubes mein driver supply auto adjust nahi hota hai. Fuse LED ko Short krne pe tube ke liye lower supply voltage ki requirement rahegi. Isliye agar short krne ke baad agar driver supply auto adjust nahi hui to baki led ko jayada supply milne lagegi aur unki life kum ho jayegi. Ek diode 0.7V ka drop deta hai to 5 diode 3.5V ka drop dega. Is tarah poori strip safe rahegi.

Haan ji, short karke abhi to chal jayega, but doosre LED samay se pahle fuse ho jayenge.

25 watt ki soldering iron sahi hai. Kum watt ka hone se led ko achhe se nahi nikal payenge.

@@ShishuTechno ok thanks, muze power supply ko wires se jodna hai, vaha se ukhad gyi hai, jaha se sab led ko supply jata hai

That is Insulated twizzler.

Ji Atul Ji aise hi karna hai, jaise battery ko series mein lagaate hain waise hi.
