This invention is regarding to an innovatively designed lens that employs two holes of different shapes as light-inlet and light-outlet surfaces to direct lights. The main feature is that the light can emit out at a more focused and uniformed fashion through refraction and total reflection. On the other hands, the lens also has grooves set to allow for side lighting purposes when needed. And with the grooves, the light can emit at a wide range when multiple such lens are properly assembled.
