A lighting unit, especially for a lighting system is described and is characterized by a carrier section which has a flattened elongate cross-section which terminates in acute angles at both ends, with all functional elements being concentrated in the central part which always has the largest vertical dimension. Changes of the dimensions lead, as a result of the selected layout to no substantial change in the outer appearance, so that powerful systems can also be realized with the same shape without impairing the external appearance.

Elongate light unit for use in a modular lighting system for generating light band type structures, said lighting unit comprising: an elongate carrier section having a cross-section resembling a double convex lens and being composed of two identically constructed, extruded, lateral profiled section each having an essentially V-shaped cross-section with an apex and ends, defining a mouth, opposite to said apex; means connecting said lateral profiled sections together at said ends with said apices forming respective longitudinal side edges of said lighting unit and with said mouths confronting each other but spaced apart from each other, whereby to form a central chamber between said lateral profiled section and side chambers within said lateral profiled sections: at least one fluorescent tube received within said central chamber; functional means comprising a choke and electrical cables and optionally other functional elements disposed in at least one of said side chambers; said lateral profiled sections including continuous webs, and undercuts forming coupling connection with modular elements to be mounted in said central region above and below said at least one fluorescent tube, said modular elements comprising translucent covers, non-light permeable covers, shield arrays and scattering grids; reflectors provided to the sides of said at least one fluorescent tube with said reflectors extending across the mouths of the respective associated lateral profiled sections, wherein said apices are slotted at said longitudinal side edges to form mounts, wherein strip-like light concentrating material is disposed in said mounts and wherein said slots communicate with said side chambers.
