Abstract
Optic entrance features may be used to optically control light transfer from a light source to a light emitting panel (LEP). In a particular embodiment, an LEP includes a first LEP side configured to emit light. The LEP also includes a second LEP side. The first LEP side and the second LEP side are opposite sides of the LEP. The LEP further includes a cutout area providing an air gap in the LEP through the first LEP side and the second LEP side. The LEP also includes a light receiving side. The cutout area is proximal to the light receiving side, and the light receiving side is configured to pass light through towards the cutout area.
