Abstract
A lightguide module having a linear collimator produced from optically transparent material, a toroidal lens produced from optically transparent material, and a light source, wherein the toroidal lens is disposed between the linear collimator and the light source, at the exit of the linear collimator are found scattering elements, and wherein a light-emitting part of the light source is directed toward an entry surface of the toroidal lens and an exit surface of the toroidal lens is directed toward entry surfaces of the linear collimator. The light source may be a light-emitting diode and the toroidal lens may be a Fresnel type lens.
