sir jab transformer se 12v milraha hai to brigretifire condenser lagane ki kyn jarurat padti hai..10 vat led ko direct transformer k 12 volt se connect nai krskte kya..sir jara explan kijiye plz..ye sab mai b sikhna chahta hu..
Immu Immu Transformer output AC h or LED DC supply pe work krta h Bridge rectifier module AC to DC DC output me provide krata h or us DC ko capacitor se filter krke use kr rhe h LED me
ANY BODY SOLVE MY PROBLEM I HAVE12 V DC 300 LED LIGHTS EACH LED 'S 1W SO 300WTOTAL LOAD NOW I WANT TO MAKE A POWER SUPPLY 220/12V PLEASE TELL ME SUTABLE TRANSFORMER OR TRANSFORMER LESS POWER SUPPLY
under rated transformer and bridge rectifier, no current limiting - this is most definitely NOT the way to make a 100w lamp - might make a nice fire though!
Hon.12 volt led chip suppose to be 10 watt,in the circuit they are 10 in numbers,so it's 100 watt,chip current? I don't understand your answer, for operating voltage as 12 watt 1 amp.Can you narrate?
so what is a point to drive them with 10x less current? if you worried to burn chips down, without CC driver, you could easily put only 2 of them in paralel, youll get near the same lm as 10, and each chip will get around 500mA, which is safe enough.
Hon. thanks, to clear my query,but but still one question,is it protected from over voltage? I won't trouble you any more, sorry to disturb you now and then.
You Mr. Prove this fact that 100 watt LED will take 100w ÷12= 10 amp including 20% efficiency. Then how only 12v one amp can do? Please prove this that 12v 1amp can drive 100watt led? Prove it mathematically
You can't produce 100w of power using 1 amp X 12 volts. That would be 12 watts. This is ohm's law. Maybe go study the concept. To use 100 watts, it would take 10 amps x 12 volts (120 watts).
Hi if each led consumes 900 ma @12 volts and if you connect 10 led in parallel it comes to the required current is 9 amps Does this 1 amp transformer gets heated quickly
Definetly: the heatsink is far to small to dissipate 100W! And the transformer is too small as well for 100 VA. So things will heat up quickly, i think.
Hon. I want to know about syska 7watt led which operates as emergency lights also, that too,only when power fails and if the switch is on (the holder in which you have plugged in the said bulb)it glows,if power fails,and switch is off light doesn't glow Curiously enough what technology or technic they have used,can you guide?
You have a great idea,can you guide me, if I want to reduce 220 volt (+ - 20%) AC to 50 volt AC and then through transformer take the output of 220 volt AC with 6:52 ampere. As I want to run 1500 Watt electrical device.
pls how can I run 48w LED on 12volts Car battery, Kindly find details of what was written on the pack it came, it was using 220 volts, I jst want you to help describe how I can run the LED on a car battery, DETAILS on Pack (-------INPUT: AC85-265V 50/60Hz -----OUTPUT: 550mA +-5%
It has and LED driver which is connected to 220 volts when it was purchased, but my project is I connect it to 12volts car battery and should give out the same output which will still power the LED
Dear MakeloGy, If I make a light for permanent use as per your directions, would it last...? Or you have done it for experiment only...? I don't have much knowledge of it but heatsink and current supply seemed to me as inappropriate that's why I asked you...
