TIRing condensing element and methods thereof |
摘要 |
A TIRing condensing element and methods thereof includes a first section and a second section. The first section provides substantially total internal reflection of light entering at a base of the first section. The second section tapers from a first section towards an optical axis of the element extending through the second section to output light from the first section. The first and second sections are configured so a half-power angle of the light output from the second section is less than the half-power angle of the light entering the first section.
