Hi all,
I am new on this forum and on electronics in general. I do have some experience with development boards but not with circuit design at all.
I am currently working on a project for which I need bright short duration pulses of light. I know this is possible using high power LED's and I am wondering where to start.
To give you an impression of possibilities have a look at these products:
https://www.vela.io/vela-one-high-speed-flash
https://gsvitec.com/en/light/value-line/
These light are often used for high speed photography or machine vision. My application is similar.
I am looking at pulse widths of ideally 100ns but 500ns will also suffice for a first try. I found some hobbyists doing something similar as well.

These LEDs are only turned on for a short amount of time and can therefore be overdriven. This results in a high light output for a short duration.
I do not understand the circuit above so maybe someone can try to explain each part to me? The comments state it can be upscaled to higher power LEDs but since I do not understand the circuit (or the basic electronics) I do not know how. I would like to trigger the whole thing with a microcontroller (probably arduino nano or teensy).
Could someone please help me?
Thank you in advance.
