Dylandrako Posted June 24, 2015 Share Posted June 24, 2015 im attempting to make a flashlight prototype that is extremely bright and have come up with all the other components needed however i am missing the backing for the filament to adaquately reflect the light without melting. if you know of a substance i could try i would very appreciative.

Harold Squared Posted July 1, 2015 Share Posted July 1, 2015 Tungsten has a very high melting point and if adequately polished might do. I have no idea how economical such a device might be but wish you success. Obviously the thickness of the reflector and the duration of exposure to high temperatures will play a role in your selection. A great reference would be "Nature's Building Blocks" by John Emsley, check it out. Link to comment Share on other sites More sharing options...
Dylandrako Posted July 1, 2015 Author Share Posted July 1, 2015 Thanks I'll look into that. The substance doesn't need to be reflective for long. It's a flash and then it's gone. Kinda like a flash bang grenade but without the bang. Link to comment Share on other sites More sharing options...
Harold Squared Posted July 3, 2015 Share Posted July 3, 2015 This requirement simplifies things for you, then. I am most pleased to have been of some assistance and curious to follow your progress. Link to comment Share on other sites More sharing options...
Dylandrako Posted July 4, 2015 Author Share Posted July 4, 2015 Not really satisfied but gave Me a small crumb to nibble on till I get more comments. Plus it kinda rude to shot down someone's ideas or to simply ignore them so I say thanks and then I look into it. Link to comment Share on other sites More sharing options...

John Cuthber Posted July 4, 2015 Share Posted July 4, 2015 A layer of silver on a thick aluminium backing would work for a short while. In general hot filaments are an inefficient way to produce light. Link to comment Share on other sites More sharing options...
Klaynos Posted July 4, 2015 Share Posted July 4, 2015 Aluminium Potential with a heat sink. You're unlikely to do better for a reasonable price. Link to comment Share on other sites More sharing options...
Harold Squared Posted July 5, 2015 Share Posted July 5, 2015 Affirmative, aluminum is widely available and easily worked, strong for its weight and a good conductor. Plus less hazardous than magnesium and more corrosion resistant. A reasonable choice to start. Link to comment Share on other sites More sharing options...
