Abstract

A device for generating light in an optical light guide, wherein the device includes an optical coupling between a light source (5) and a light guide (2), wherein the light source is adapted to transmit visible light or visible and ultra-violet light, wherein the light-generating element is enclosed in a glass bubble (9), wherein the light-generating element is a light arc or an electric filament, and wherein the glass bubble has a radius which corresponds generally to the length of the light-generating element. The invention is characterized by the combination that the cross-sectional dimension of the inlet orifice (8) of the light guide (2) has respectively a length and a width which corresponds generally to or is generally greater than the respective length and width of the light-generating element of the light source (5) in the same plane as the length and width respectively of the light-generating element, and the distance between the outer surface of the glass bubble (9) and the inlet orifice (8) of the light-guide (2) is shorter than the length of the light-generating element.
