Hi
I have decided to make a LED torch. I am going to run it at 450mA, (max. is 500mA) off a 555 timer (30KHz, 50% Duty Cycle).
The only problem is cooling it. I have attached a small heat sink. A big one is not possible, the housing is too small and I cant have a bigger one.
Is there an electronic way of ensuring the LED stays cool without loosing too much light intensity?
Thanks Heaps
