Abstract (en)

[origin: DE10234124A1] A fiber-optic light guide (14) has two light channels (5) each with coupling and decoupling points. A light signal is carried through each light channel to a projection surface. A luminous element (12) has a Bragg mirror, through which a dihedral angle for scattered light can be adjusted. The luminous element has a source of coolness/heat to control the temperature of the Bragg mirror.
