| Abstract |
We studied prism design method for actual light source that have bulk in order to accomplish particular intensity distribution. When we know incidence angle and try to send ray to given direction, numerical formula that yields prism vertical angle, and then vertical angles were calculated sequentially. After analyzing problem that supposing to point light source, supplemented this and derived applicable prism design method on bulk light source. The intensity distribution and efficiency that carre out by each design results were compared and analyzed, we got improved results through supplemented design method. |
