Information about Led Beam Angle

- Nov 02, 2018 -

Led luminescence Angle refers to the Angle of Led luminescence, which is the Angle of light scattering. It is mainly controlled by adding scattering agent when diode is produced.



There are three broad categories:



(1) high directivity. It is usually encapsulated with a pointed epoxy or a metal reflecting chamber without scattering agent. Light Angle 5 ° ~ 20 ° or less, has the very high directivity, can be used for local lighting light source, or with light detector combined to form an automatic test system.



(2) standard type. Often used as indicator light, the light Angle of 20 ° to 45 °.



(3) scattering type. This is a bigger light Angle, light Angle 45 ° to 90 ° or greater, the amount of scattering agent is bigger.
