Abstract
A system can include a light emitting diode (LED) and a transparent structure disposed over the LED. The transparent structure includes a first surface that reflects light extracted from the LED and incident on the first surface. The transparent structure also includes an exit surface opposite the first surface. The exit surface includes a first area that is textured to diffuse light over a first angular range and a second area that is textured to diffuse light over a second angular range. The second angular range is wider than the first angular range.
