Hello Guys and gals.
I will try to explain my DIY project on this thread. I am a dentist (my wife is a dentist too and she is the one wants to have the light on her loupes) who hates to be ripped off :scowl: and refusing to pay £300 (at least) for a 3w LED, an aluminium case and a battery pack.I have no electronic knowledge and skills but I am good at finding solutions (at least thats what I think).
I have looked for DIY project or a simple conversion of a decent torch in to a LED headlight but I cant find a completed guide including this forum. All I can find here is half way projects and ideas.
I initially bought a cheap dental LED headlight from e-bay. It was claiming it was that it was a 3W LED but it was not. However it gave me a chance to try different optics I harvested from different cheap torches and jeweler loupes. Even the LED is not powerful enough, I managed to get a bright focus but this was not really homogeneous and there was some considerable spill around it. I thought, if I could have changed the LED with 3W power LED, possibly I could have had a better light. So, I have decided to find a decent torch to harvest parts and try to assemble them. I have purchased a couple of LED Lenser TTs( they have not arrived yet).I am hoping to get a bright and homogeneous light in the end. I am planning to use an aluminum round shape apertura (made from iphone's back cover, widely available, cheap or even free) to let the light shine through a small hole to create a small area. If TT's flood light is powerful enough on short distance, I am hopping w/o any more adjustment I will get something good enough. If not I will try to create improve it's focus light with some other optics.
If you dont mind me asking I have some basic question.The dental loupe I purchased has a battery unit. I opened it up and they are a couple of AA size batteries connected with a small electronic unit which makes possible to adjust the light intensity.Do you think I can use this pack to power up TT's LED(TT originally uses 3 X AAA battery) ?Will the potentiometer ( I guess this is the name of the part of the device to adjust brightness) work on TT's LED.a
As soon as I have TTs I will send pictures of the project. Please do not forget when commenting , I am not very knowledgeable about LEDs, electronics and optics:mecry::thinking: and dont get frustrated with me please
