In this video i will show you "How to make a 20 watt led emergency light " XL6009 DC-DC Step-up Module ;- amzn.to/2Muy9Ej 20 watt led Pvc switch box On off switch Led Charging port Diode 4007
Mere Bhai 20 watt ki led garam hoti h use Bina horsink k plastic par Jala Raha h or sath me dc to DC ki watt malttimitrr k Bina chak karke Chala Raha h Kya mahan h tu kya ho Gaya h aaj Kal koi bhi anadi video bana raha h
Bhai jo tu light banaya hai na usme 2 paroblm hai fast hitsing nhi lagaya second jo tu ye dc 2 dc canvarter lagaya hai us se 10 minutes nhi chalega uska I.C jal jayega 💯 mai use kark dekha hu faltu me logo ko bewkup mat bna
plastic box will melt ha ha..if u convert 3.7 volt to 12 volt..u can get 800 mah only ,,this board working principle is I to v converter,,so without heat sink u cant get above 1 ahms
aqui no va los modulo tp4056 y dc dc convertidor si hay muy caro todo caro no se puede ojala tenga a mi alcanse me divierto un rato aparte de provecho para una luz de todo andar saludo of argentina kapoo!
It won't the battery carries 3.7 volts by using boost converter there will be power loss and also boost converter won't able to keep same voltage as battery be going down. This is merely a flashlight rather than emergency one
20 watt LED thoda heat hota hai।। Aap chahe to use kar sakte heatsink । Main one hour isko trial me rakha tha।। Heatsink ki jarurat nahi samjha isliye nahi lagaya।।।।
Sir yeah circuit Maine mangwaya that tha magar iski output 5v input 4.5v output dikha raha tha Maine preset se screw bahut ghumaya magar voltage increase nahin hue fir Maine yeh circuit return kardiya. IS circuit ki voltage ko kaise check karte hai inme 2 type ke circuit aate hai single stepup aur stepup and step down on single board
Maine step up circuit use Kiya hai।।Output me multimeter lagake test Karna Hoga।। Preset ek taraf ghumane se up hota hai or ek taraf ghumane se down hota hai।। Aap ko prest right left dono taraf hi ghumake dekhna chahiye tha।।
Az ötlet jó, de hiányos. A LED-hez a hűtőborda hiányzik, a Li-Ion akkumulátorhoz a TP4056-os töltő modul, és az ilyen mobil akku semmire se jó, de helyette a Sanyo 18650-es akkukat (párhuzamosan) kellene használni. De az ötlet jó.
