Diode Luminous Intensity And Light Intensity Distribution

The luminous intensity of LED is to characterize its luminous intensity in a certain direction. Since the luminous intensity of LEDs varies a lot at different spatial angles, we have studied the luminous intensity distribution characteristics of LEDs. This parameter is of great practical significance and directly affects the minimum viewing angle of the LED display device. For example, in a large-scale LED color display in a stadium, if the selected LED single tube has a narrow distribution range, the audience facing the display at a large angle will see a distorted image. And traffic lights also require a wider range of people to recognize.
