The luminous intensity of an LED is a characterization of its luminous intensity in a certain direction. Since the luminous intensity of the LED is very different at different spatial angles, we then studied the luminous intensity distribution characteristics of the LED.
This parameter is of great practical significance and directly affects the minimum viewing angle of the LED display device. For example, large-scale color LED display screens in stadiums, if the selected LED single tube distribution range is very narrow, then the audience facing the display screen at a larger angle will see a distorted image. Moreover, traffic sign lights also require a larger range of people to be able to recognize.
