Abstract
An LED lighting assembly includes a circuit board, a number of light emitting diodes (LEDs) overlying the circuit board, and optical element is proximate each LED and separate from other optical elements. Each optical element includes a first portion and a second portion that intersects with the first portion in a region between the first and second portions. The first and second portions are shaped so that at least one surface normal of the first portion intersects with at least one surface normal of the second portion, and the first and second portions are configured so that light from the associated LED exits the associated optical element through the first and the second portions. Each optical element also includes a third portion extending beyond the region between the first portion and the second portion in a direction away from the associated LED.
