A lighting device for streets, having a housing for receiving at least one lighting module can be mounted easily if it comprises a plurality of lighting units having a light element and an optical element associated with the same and being fastened on a carrier. The module housing is covered by a sealing pane facing the lighting units and comprises fastening means for removably fastening same on the housing. Electrical contact means are provided on the module housing for electrically connecting the lighting units to an external voltage source, wherein the fastening and contact means are designed such that the lighting module can be brought from an assembled position, in which the lighting module is mechanically and electrically connected to the housing, to a disassembled position in which the lighting module is not mechanically or electrically connected to the housing, and vice versa, exclusively by means of a linear displacement.
