All Facts for Choosing LED Optics Correctly
... For all modern small light sources with one to four dies and a primary lens, the best solution to use, from optical point of view, always is a lens. The explanation, why a lens is the best, is simple: in a lens, the beam can be controlled very well. There are at least three surfaces for use, while f ...
