1. It is usually used as indicator light, and its half value angle is 20 °ถึง 45 °. At present, most of the outdoor display screens are of horizontal view angle of 100 °, vertical angle of view of 50 ° and scattering type

2. This is an elliptical led with a larger viewing angle, and the indoor LED display screen is selected to be 120 ° horizontally and vertically;

3. High directivity. It is usually encapsulated in epoxy resin with sharp tip or with metal reflective cavity and without scatterer. Because of its particularity, the LED display screen on the highway is generally 30 ° and the circular LED display screen with viewing angle is enough. Some high-rise buildings have high requirements for vertical viewing angle. The angle of view and brightness are contradictory to each other, and large angle of view will inevitably reduce the brightness. The choice of perspective depends on the specific purpose.
