Design of LED Flat Light Based on Double Free-form Lens
This paper presents a lens design method for LED flat lamp.In order to achieve a wider range of output light mixing and better light output efficiency,LED lamp beads are used as the light source,and a special lens structure is designed for flat lamps.By optimizing the geometry of the mixing lens and the arrangement of the LED light source,the effective control of the mixing light is realized,and the mixing effect and brightness uniformity are improved.The computer simulation results show that the designed LED flat lamp lens has higher light mixing effect and lower energy consumption,which is suitable for various lighting application scenarios,and provides a new application direction for LED lighting technology.
