The luminous intensity and intensity distribution of LEDs

The luminous intensity of LED is a representation of its luminous intensity in a certain direction. Due to the significant differences in luminous intensity of LED at different spatial angles, we have studied the distribution characteristics of LED luminous intensity. This parameter has great practical significance and directly affects the minimum observation angle of LED display devices. For example, if a large LED color display screen is used in a sports stadium, and the distribution range of the LED single tube is very narrow, the audience facing the screen at a larger angle will see distorted images. And traffic signs also require a large area of people to be able to recognize them.
