OK, I have a requirement to take pictures with a flash at the rate of 3 per second for 10 seconds. The range of the flash needs to be about 50' and cover an area about 15' square at distances from 20' to 50'.
I am wondering if anyone has used LEDs to build a camera flash and what challenges exist when using LEDs in this type of application. I have searched but all the LED flash info I have found so far is about camera phones.
It doesn't really matter if I have to use multiple LEDs and drivers or whatever. (Budget shouldn't be an obsticle.)
My thought was to leave the light on until the photos are taken but the requriement is for it to work like a flash.
Some questions that come to mind.
1. Are LEDs fast enough?
2. Can I eliminate the charging circuit that standard flashes need?
(Assuming yes, which is really the point of using LEDs.)
3. Will using LEDs like a flash, quick frequent cycling, cause degredation?
4. How many lumens are produced by standard 400 Watt flashes? (What we currently use. These illuminate a much larger area than required though.)
Thanks for your help.
