The present invention is directed to a device for changing a fluorescent light, in particular a compact fluorescent light. The activated carbon contained in the filter layers serves as a gas filter that, by absorption, at least partially removes the noxious gases that are contained in the air inhaled. When the resistance detector detects the electrical resistance, the controller selects the first transfer mode. Said solid catalyst component can be advantageously used as a solid component in a catalyst for the polymerization of \u03b1-olefins. The first and second barrier regions in this structure restrict transmission of water and oxygen from an outer environment to the optoelectronic device. A hydraulic pressure generator having an electric motor with variable electric input is employed to provide a corresponding a proportional hydraulic pressure by a hydraulic pressure generator, wherein the resulting variable hydraulic pressure is employed to provide a proportional braking force in the towed vehicle.
