I’ve finished my LED torch conversion. I did this a while ago but forgot to post details of it here.
Previously i had fixed the LED into the body of the torch with a heatsink. Since this is a wide angle torch, i need to mount a lens on it in order to focus the light beam. I bought a 15° lens and holder and tried to figure out a way to mount it. Originally i was going to make a frame for it either from an aluminium disk or from a pliable material such as sugru. In the end i discovered a much simpler option:
Ok, so i designed my torch. This is fine but designs are no good unless you actually put them into practice. This is quite a quick build that goes together nice and quickly and has some nice satisfactory results:
I have this brinkmann 3xLED flashlight. I bought it in a walmart in the USA a few years ago for next to nothing. It isn’t very bright but the body is completely aluminium and the overall build quality is pretty good. I’ve been wanting to supercharge it for a while now so i bought some 3watt star LEDs from bestshop2008hk on ebay. My idea is to use one of these in the flashlight. I’ve put together a simple design to help accomplish this, including a way of heat sinking the LED to the torch case. Read more to see the design.
