Research on LED Lighting Secondary Light Distribution by Using a Freeform Lens
Application of semiconductor lighting is widespread, so its secondary light distribution design of the LED for lighting plays an important role. For LED road lighting applications, its uniformity of illumination need to meet certain requirements, a freeform surface using freeform optical lens was designed, in the secondary light distribution. Because of the application of freeform lens, LED lighting illumination uniformity has been improved. Lighting simulation and analysis, results indicate that based on freeform lens, LED lighting has good illumination uniformity, and has well research, development and application prospects.
