Patent ID: 7686497

Claim:
A light guide module for motor vehicles and directing light generally along a horizontal axis, the module comprising: an array of light sources; an array of reflectors; a light guide defining a body having opposed upper and lower walls, at least one prismatic structure defined in the lower wall, the prismatic structure having a reflecting surface oriented to reflect light in the light guide based the principle of total internal reflection and to redirect light toward the upper wall, at least one decoupling prism element defined in the upper wall, the decoupling prism elements corresponding in number to the at least one prismatic structures, the decoupling prism element being located in a position in the upper wall so as to receive redirected light from a corresponding one of the prismatic structures, the decoupling prism element including a second reflecting surface to reflect light redirected from the first reflecting surface, the second reflecting surface reflecting light toward an output surface based on the principle of total internal reflection and defining a vertical spread of light; and whereby light emitted from the output surface of the decoupling prism element is directed generally along the horizontal axis.
