Does the luminous intensity of leds of Unicorn HAT HD changes by angle? If so, how does it changes? This question is crucial for the project that we are doing.
Mine are behind the Black Ninja Diffusers, If the brightness decreases at side angles I can’t detect it just by looking at it.
Often, but not always, the datasheet for an LED will have a diagram showing the change in luminous intensity with angle. I don’t know exactly which LEDs Pimoroni used, at a glance this one is the closest I can find, and the datasheet has diagrams on page 6 describing this.
