DEC #09 Constant Current High power LED driver using LM317

In this video I have demonstrated a very simple and easy method of driving high power led with LM317 IC. Its very cheap and easy to find. So anyone can use this IC to drive any high power LED just by replacing the current limiting resistor. To calculate the value of resistor you may read the blog from my website and get the schematic: digitaleclab.com/high-power-l...

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...

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

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

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?

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

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 2 жыл бұрын

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

@RobertLugg Жыл бұрын

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.

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?

@xsauce3858 2 жыл бұрын

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

@Jenyaza01 Жыл бұрын

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)
