The very first thing you must do is to check whether or not the LED is linked to the circuit correctly. LEDs only permit present-day to movement in a single path. Try very first disconnecting your LED and switching the connections about.
The technological storage or entry that is certainly utilised exclusively for statistical functions. The technological storage or access that is definitely utilised solely for anonymous statistical applications.
The circular strains symbolize the intensity by % of highest intensity. This LED has a fairly limited viewing angle. You could see that looking straight down at the LED is when It really is at its brightest, due to the fact at 0 degrees the blue traces intersect Along with the outermost circle. To get the fifty% viewing angle, the angle at which the light is fifty percent as extreme, Keep to the 50% circle throughout the graph until it intersects the blue line, then observe the closest spoke out to read the angle. For this LED, the 50% viewing angle is about twenty degrees.
