Haha but it won’t impress the luxmeter!
The first place this “recoil” design was used was in a small flashlight a long time ago:
There was a lot of discussion about it on this thread for anyone interested:
We tried stuff like solar cigarette lighters, vanity mirrors, and some other cheap parabolic mirrors, but none gave a well defined or focused spot.
Some guys over on the german forum are also working on a recoil design like mine, but they are planning to use 3x 24” lower quality reflectors.
Won’t really be a flashlight though, more of a stationary spotlight.
I finally decided to save up and purchase high quality precision mirrors for this project, we will soon find out how well they can match my theoretical estimates.
Also, I am building two prototypes, they are not both going into one flashlight.
