Photographic Led flash

It’s not flashing...

It s only a simulation, you need to adapt the components to your needs ') in the simulation you can simply change the value of C and slow the Sim. Time

Fixed for a real application 😁

if you have a good mosfet with low Rdson you have 30V minus 2V LED and only a 10Ohm current limiting resistor which makes 2.8A maximum current and will mostlikely destroy the little 20mA LED with a single flash !

Lenny, this is not like yours ⭐Rapid⭐modern⭐economical⭐versatile⭐flashing⭐ flash is here a single event and the flash has to be prepered to flash again. Learn how this circuit work. See the little bobbles on the wires they will help you to see where the current is going. But most importante, before you say its not working, ask a little question and you get help

@hurz... You continue to use Mosfets with an unrealistic Vth in your presentations. You have no idea when it comes to overdrive considerations, and you have only recently started to use the word 'overdrive' having seen me refer to it for many months. You are the ultimate fraud who criticises others for knowing little, whilst in reality you have massive gaps in your understanding of various aspects of electronics... You knew nothing about shootthrough, you don't understand the workings of an RC integrator, and you continue to scour google 24/7 in an effort to present knowledge in the hope of conning viewers in to thinking that you know everything by some kind of divine right or superior ancient learning structure... Fraud indeed.

Mr @2cent messy, this is not my circuit, if you want to take it over im keen to see what you do with it. What is that for an impertinent propaganda. Your are better then Göbbels, you are a Nazi ! Come with facts and stop your bullying drivels. Imposter, which words i learn late in english is my problem and not yours, i know my stuff in german but here and there i might habe gaps in english titles of things. Dont worry imposter i know my stuff !

It's not flashing

it does flash but only ones. Make use of the switches its not an oscillator, i know, this is what noobs expect if they see ⭐flashing⭐ but its not

@hurz you are right about the 10 ohm resistor. I put a potentiometer to adjust the current based on the led size, I was thinking about a 100W led, with about a 25 V of voltage drop on it. And a maximum current of 3A. But I never tried it before so you may be right. I will appreciate any of your suggestion guys anyway :)

So nazi @2cent and bullying troll Lenny you see? No, cuz you neber understand the basics of electronics. @dd92, go ahead play with it, buy a cheap LED and gibe it a try, but be careful with overcurrent over a to long time. Keep obercurrent short

In a real application it is supposed to be used with a dissipator on the led i think 🤔

you mean heat sink? thats a nice idea but can only help to cool down for long overcurren. short will continue to destroy the LED. Keep in mind a LED comes with positove temperatur coefficient as warmer it gets as higher its resistance or better said threshold voltage. So a cool LED will pass higher current to be quicker destroyed the a warm or hot LED. See heat in this case even as self protecting mechanism.

Understood, thanks! 😀 I will take a look a the data sheets first
