摘要：
A lighting device includes LEDs and optical elements. Each optical element is associated with one of the LEDs and each LED is associated with one of the optical elements. Each optical element includes a first portion, a second portion, and a third portion. The second portion of the optical element intersects with the first portion of the optical element in a region between the first portion of the optical element and the second portion of the optical element. The first portion of the optical element and the second portion of the optical element are shaped so that at least one surface normal of the first portion of the optical element intersects with at least one surface normal of the second portion of the optical element.
