The lighting fixture is designed for a pair of two tubular fluorescent lamps and comprises side reflector plates being mutually connected by means of a number of equidistantly spaced transverse reflector plates. Each side reflector plate comprises an upper strongly curved portion passing into a lower less curved portion. The lighting fixture futhermore comprises top reflector plates above the fluorescent lamps and the invention is characterized in that these top reflector plates have the same cross sectional shape and dimensions as the mutually identical side reflector plates whereby they are mounted conversely of these i.e. that the less curved portion extends over and out from the corresponding fluorescent lamp while the strongly curved portion is situated between the two fluorescent lamps with its edge abutting the corresponding edge of the opposite top reflector plate, the abutting edges being abreast of the fluorescent lamps, preferably their axes. When using identical reflector plates not only a reduction of manufacturing costs is achieved, but also a substantial economy of transport costs for individual parts so that the assembly of the lighting fixture advantageously can be performed by dealers or electricians. Surprisingly, a better light efficiency and a uniform lighting degree of illuminated surface is achieved compared to known lighting fixtures of corresponding types, i.e. comprising both side and top reflector plates.
