1. A method of illuminating an area using an apparatus comprising a light assembly that includes a plurality of light emitting diodes (LEDs) and a plurality of optical elements, each optical element associated with one of the plurality of LEDs and each LED is associated with one of the optical elements, the method comprising:
directing light from the plurality of LEDs toward the area, wherein directing the light comprises directing the light from each LED of the plurality of LEDs through the associated optical element such that light exiting from each optical element of the plurality of optical elements is directed across all of the area; and wherein each optical element of the plurality of optical elements includes
a first element comprising a first convex-shaped surface,a second element comprising a second convex-shaped surface that intersects with the first convex-shaped surface at an acute angle in a region between the first element and the second element, wherein the light from the associated LED exits the associated optical element through the first and the second convex-shaped surfaces, anda third element extending beyond the first convex-shaped element and the second convex-shaped element in a direction away from the associated LED.
