How do LED lenses work? | How to assembly LENS to LED lighting?

 

A lighting assembly includes a number of LEDs and an optical element proximate each one of the LEDs. The optical elements are configured to direct light from that LED toward an area, such that the light intensity from each optical element is substantially uniform across all of the area. Each optical element includes a first element, a second element, and a third element that extends beyond the first and the second elements.
