Compact lighting system and display device

摘要

A compact backlight system for illuminating a display device has a front wall and a rear wall situated opposite thereto. At least one light source comprising a light-emitting diode is provided with a translucent lens-shaped cover. The system has at least one light input structure for coupling light from the light source into the light-emitting panel. During operation, light originating from the light source is incident on the light input structure and distributes itself in the light-emitting panel. According to the invention the light input structure is conically or frustoconically shaped towards the light source. The thickness d_p of the light-emitting panel is smaller than the diameter d_c of the translucent lens-shaped cover of the light source. Preferably, the light input structure is of prismatic or pyramidal shape.
