    Simple explanation of why it is preferable to use a driver to run leds , thank you for your easy to understand /follow video, subscribed.

    Very Nice Instructional. I have read thousands of datasheets and they are your best friend. Thanks for pointing that out.

    Well done. Clear the demonstration of the LM317 used as a current regulator, its low efficiency, all with the instrument. It's not so difficult to make a video in such a way, but just few people do...

    Thanks! You have explained well. Using this circuit if I want to regulate the brightness of the led, what should I do? Can you make a video on that?

    It was simple. Thank you and can you please make an LED driver that takes an AC input? Like the one in LED tubelights.

    thank you so much. if i want to connect two of these led rgw of 3W with one regulator is ok? or i´ll should use two?

    I have a question in my mind in monitor shows that led received 237mah but at same time 8-20v also (when you increase voltage) so, my question is will led be damage due to high voltage?

    • @prakashdev6008
      @prakashdev6008 3 роки тому

      Excess voltage will be dropped across the IC, not across the LED

      I guess even though the power source voltage is increasing the purpose of the IC is to perfectly adjust its voltage such that current stays constant.

    Can this also be used for transient?

    i have 3 18650 batteries and 3 1Watt leds which draws 350mA current each. how can i use these batteries to run 1Watt leds at 350mA constant current for each led. i want to use 3 18650 batteries in parallel to have more capacity but output will be 3.7-4.2 V. Please help

    Good Video. If i want to use 10-12 5mm led, what is the resistance should i have to use? Will the circuit be the same? Please help

    Is PWM not better?

  • @bartwoolery9403
    @bartwoolery9403 2 роки тому +1

    aren't the resistors dissipating most of the power (and not the IC)?

    • @kfoltman
      @kfoltman 2 роки тому

      Depends, the voltage across the resistors is fixed at 1.25V, so the resistors only dissipate 1.25V * set current (300mA), the IC takes the rest.

  • @xsauce3858

    How efficient is that method compared to a resistor in series with the LED ?

    • @Jenyaza01
      @Jenyaza01 Рік тому

      Same, but you need to calculate correct resistor value, and can`t change working voltage later (you can, but then need to recalculate resistance once more)

    Transistor is getting so hot ! Any solution? I even attached heatsink too! Still get hot so much!

    • @epicoddgamer2900

      Lower the voltage i guess

      The small vin-vout, the small heat. So you should have vin-vout about 4 volt.
