High Powered Piranha LED Flashlight

January 28, 2013

Recently I was working around LED’s and therir diferrences, with that I have also posted topic about comparing Pirahna FLUX LED’s with normal 5mm high brightness ones. That comparison gave me an idea to create small Flashlight with Piranha LED’s.  At first I wanted to make it portable but problem I encountered is powersource.  Due to that fact for startes I have created non portable but moving LED flashlight. I was preety amazed how much power this little combination can give.

For Project I have used small black box with screwed top on one side. On one side i have cutted out square piece and fitted small plexiglass from within for protection due to heat. On top of it I have mounted flip switch for turning flashlight on and off and on bottom normal powerjack input for wall adapter.

I have used 16 cold white high output Piranha FLUX LED’s with four pin on each all paralled connected trough dedicated resistors for each LED. I had to use aditional positive wires to top of the rows due to lack of power with just one trace.

All LED’s are conected via +5V voltage regulator which is glued to dedicated heatsink. I must say that even with that heatsink on whole back of case becomes very very hot after 10 min of constant use.

And for final here are results of brightness of that device in lid space and complete dark space. First pictures of flashlight working in lid space with 130W lightbulb.

Hope you liked this little procjet and if you have any ideas how to make this flashlight portable and with less heat dissapating feel free to leave a comment or send me an e-mail.
