Compact lighting system and display device
First Claim
1. A lighting system provided with a light-emitting panel comprising a front wall, a rear wall situated opposite thereto, and furthermore, between the front and the rear wall, a first edge surface and, opposite thereto, a second edge surface, the first edge surface being light-transmitting, while at least a first light source is associated with the first edge surface, and while, in operation, light originating from the first light source is incident on the first edge surface and distributes itself in the panel, characterized in that the light-emitting panel widens over a widening section from the first edge surface in a direction towards the second edge surface, and in that the rear wall is provided over the widening section with a multiplicity of steps of which a surface facing the front wall is substantially parallel to the front wall.

Abstract
A compact backlight system has a light-emitting panel (1) with a front wall (2), a rear wall (3) situated opposite thereto, and furthermore, between the front and the rear wall (2, 3), a first edge surface (4) and, opposite thereto, a second edge surface (5). A first light source (6) is associated with the first edge surface (4) which is light-transmitting. According to the invention, the light-emitting panel (1) widens over a widening section (100) from the first edge surface (4) in a direction towards the second edge surface (5), and the rear wall (3) is provided over the widening section (100) with a multiplicity of steps (13, 13′, . . . ) of which a surface (17) facing the front wall (2) is substantially parallel to the front wall (2). Preferably, the ratio of the surface area S1 of the first edge surface (4) and the surface area S2 of the second edge surface (5) ranges from 1.5<S2/S1<3.
