ILLUMINATION LENS FOR LED BACKLIGHTS

摘要

A light-emitting apparatus having a 16:9 geometry includes light-emitting elements disposed on a first substrate or a second substrate, light flux control members respectively disposed on the light-emitting elements and on the first or second substrate, and a film stack disposed above the light flux control members. Each light flux control member includes a bottom surface section disposed on the first or second substrate, a non-rotationally symmetric input surface section having an inward recess disposed in the bottom surface section at a position directly above one of the light-emitting elements, and a non-rotationally symmetric output surface configured to refract light passing through the input surface section, and to transmit light outside. The light flux control members disposed on the first substrate are spaced 100 mm apart from each other in a first direction, and the light-emitting elements are spaced 23 mm away from the film stack.
