SUBSTANCE: group of inventions refers to the lighting glazing, which is the part of the roof of the vehicle. Glazing comprises the glass or plastic transparent sheet (1) with the first main side (11), the second main side (12) and the rib (13), the planar waveguide (3) with the first main side (31), the second main side (32), the injection rib (33), and the bevelled edge (34), opposite to the injection rib, the light source (2), which is located opposite the injection rib (33) of the plane waveguide (3) and has sufficient power in order to supply the light flux of at least 35 lumens (lm). Planar waveguide (3) is fastened with its second main side (32) to the first main side (11) of the glass sheet (1). Sharp angle formed by the beveled face (34) together with the first main side (31) of the waveguide (α) is from 10 to 80°.

EFFECT: opportunity to orient the light in the certain direction and to limit the scattering angle of the output light is achieved.
