The circular lines symbolize the depth by percent of greatest depth. This LED has a fairly restricted viewing angle. You'll be able to see that wanting straight down for the LED is when It really is at its brightest, for the reason that at 0 levels the blue strains intersect While using the outermost circle. To find the fifty% viewing angle, the angle at which The sunshine is 50 % as rigorous, Adhere to the fifty% circle around the graph until it intersects the blue line, then observe the closest spoke out to browse the angle. For this LED, the fifty% viewing angle is about twenty degrees.
Aug 29, 2012 Hey there wonderopolis! I am sorry to mention but this video was seriously lousy. It absolutely was only a man snowboarding or what ever he was accomplishing. I love this Web page but do not like the topics and also the films, They are really just so uninteresting.
