Abstract

See full text

In at least one embodiment of the surface light guide, the surface light guide includes at least one scattering element for scattering light. A decoupling coefficient is caused by the scattering element. The decoupling coefficient is set in a varying fashion along a main light-guiding direction. In a direction perpendicular to the main sides of the surface light guide, the opacity value is no more than 0.10, the transmission coefficient is at least 0.75 and the quotient of the minimum light density and maximum light density seen over a continuous emitting area of at least one of the main sides is at least 0.75.
