Abstract:
1. An adapter set for fluorescent lamps with two fluorescent lamp sockets for conversion to a fluorescent tube having smaller diameter, comprising: an electronic ballast held in an electronic ballast housing, two adapters which are formed respectively by the electronic ballast and by an end cap adapter, wherein the electronic ballast and the end cap adapter each include contact pins on one axial face thereof with dimensions of fluorescent tubes having greater diameters for receiving in two fluorescent lamp holders and on the other opposing axial face thereof include contact holders for receiving two contact pins of the fluorescent tube having smaller diameter, and wherein the electronic ballast housing on the axial face opposite the contact pins thereof or on the axial face facing the fluorescent tube having smaller diameter has an opening which is sealed by a flange housing, wherein the flange housing is detachably connected to the electronic ballast housing and is equipped with electric plug contacts which make an electric connection to the contact pins of the end cap adapter and the electronic ballast housing by means of electric wiring, wherein the flange housing on an axial front thereof facing the electronic ballast housing has an opening through which the fluorescent tube having smaller diameter can be changed, and the flange housing receives a transparent or translucent jacket tube which encloses the fluorescent tube having smaller diameter in a protective manner, wherein the outside diameter of the jacket tube corresponds to about the outside diameter of the fluorescent tube having greater diameter, and at least one cable channel extends axially relative to the jacket tube within or outside of the jacket tube, the cable channel serving as a lug for the wiring of the electric connection between the contact pins of the end cap adapter and the electronic ballast.
