    Abstract: A lighting module for the stationary illumination of traffic routes comprises a plurality of light-emitting diodes and a light-shaping element. The light-shaping element comprises a plurality of refractive optical free-form surfaces for shaping light and at least one light-scattering area, which is configured to radiate, during the operation of the lighting module, diffused light originating from the light-emitting diodes. A traffic route luminaire comprises a housing and a plurality of lighting modules that are disposed in such a way in the housing that the longitudinal axes of the lighting modules extend next to each other and parallel to each other and the light-radiating faces of the lighting modules are disposed in a sawtooth shape relative to one another. The design according to the invention on the one hand enables a good illumination of the traffic route area and, on the other hand, prevents glare or disturbance to passers-by or residents.
