Hi,
I have seen some LED driven devices project a little rectangle
(unfilled) at a distance of upto 10cm or so - i am wondering how this
is done.
Is it just a matter of a special lense infront of uBright LED's ?
If so, where can i get these lenses, and what are they called.
I cant seem to find anything through my google searches.
(i can not take apart the above mentioned device to have a closer
look, but it is definantly LED's).
