Research on Multi-Direction Collimation Beam on the Plane Parallel with LED Lighting Plane
Multi-direction collimation lens based on light emitting diode (LED) is proposed, the total internal reflection multi-freeform surface is employed to realize multi-direction collimation. Lambert type light distribution of LED is researched, and lens are used to change the light distribution. The coordinate value of points on freeform surface is calculated by Matlab software. Combined with the 3D software and TracePro software, multi-direction collimation lens are designed. Multi-direction collimation beams are in the same plane which is parallel with the light-emitting plane of LED. Each divergence angle of collimation beam is merely 3°.
