DEC #09 Constant Current High power LED driver using LM317

[@ddistrbd1]

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

[@SteveSnowman]

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

[@sumitnarkhede.3105]

EXCELENT SIR JI.FOR BEST SIMPLE AND DETAILED EXPLANATION.

[@olivierijazz]

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...

[@TitasMajumder_2003]

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?

[@cpk001]

Very well explained

[@sledzeppelin]

Excellent video. Very easy to follow.

[@er.imransiddiqui]

Very informative and helpful. Thanks a lot. Also explain with switching regulator plz

[@prakashashara6065]

Wah bhai nice information

[@rajaravivarmar]

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

[@ulsdigital]

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?

[@vinodsao4465]

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]

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

[@RobertLugg]

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.

very useful.thanks

Thank you

The link in the description is broken, it leads to a website with an invalid security certificate.

[@jesusreignonhigh6732]

Can this also be used for transient?

[@bartwoolery9403]

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

[@kfoltman]

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.

[@krishnaswamy516]

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

[@MothKeeper]

Put some bean juice in there.

[@paulb9769]

Is PWM not better?

[@xsauce3858]

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

[@Jenyaza01]

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)

[@easytechsolutions3311]

Amazing

Thanks

[@jasonclouthier3990]

Hi I need to wire 4 LEDs and 4drivers can you show me how to wire it?

[@mayureshkulkarni4791]

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

[@amitrajput6904]

Good

[@SAI_LINGESH]

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

[@epicoddgamer2900]

Lower the voltage i guess

[@PhongHuynh0981314893]

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

[@ДедПул-н7э]

30шт, 3 Вт, 45 мил, 380нм-840 нм, 3,2-3,6 В, 700 мА, как собрать драйвер? подскажите пожалуйста

[@prahalladdas6329]

Sir, kindly give me a 30 watt LED driver circuit diagram using most common indian components.thanks.

[@DigitalElectronicsCircuitsLab]

ok sure. But tell me you want to drive the LED from mains AC or 12V batt?

[@maleki1300]

Ino understand
