OPTICAL ARRANGEMENT
First Claim
1. An optical arrangement having a light source, which emits a beam, and having a light guide, which has a light-guiding layer, in which a coupled-in beam is guided between two substantially mutually opposite surface-type reflection layers, wherein the optical light paths of the individual rays of the beam, in particular at least of the marginal rays, from the light source to impingement on one of the reflection layers are substantially of equal length.
