The effects of high-power LED inner structure on the radiation patterns

This research uses optical simulation software TracePro to analyze the effects of inner lens structure on the radiation patterns. There are three inner lens geometry parameter structure: Radius of curvature(at corner)(r), Width (w) and Height (h). This research probes into the effects of radiation pattern by changing the parameters of the radiation pattern changes with inner structure. The effect of inner structure on the radiation pattern is performed by changing three geometry parameters. The results show that the geometry parameters are different and they will be impacted by the distribution of radiation pattern.
