Abstract: The invention relates to an industrial robot, comprising a movable carriage (2, 22, 42, 52-1, 52-2), on which a working device (3.1, 23.1, 43.1) is vertically movably supported and can be lowered from a first area above a safety plane to a second area below the safety plane. A protection device is arranged in the safety plane and, in a first position, prevents the working device (3.1, 23.1, 43.1) from lowering from the first area to the second area. In a second position of the protection device, the working device (3.1, 23.1, 43.1) is able to lower to the second area. The protection device is attached to the movable carriage (2, 22, 42, 52-I, 52-2) and associated with the working device (3.1, 23.1, 43.1) such that the protection of persons and machines is ensured using a simple design.

Abstract: A headlight for vehicles has a light source formed as a gas discharge lamp, a ballast unit connected with the gas discharge lamp and producing high voltage, and a unit for preventing dispersion of electromagnetic radiation caused by the gas discharge lamp. The unit includes an electrical filtering circuit arranged near the gas discharge lamp and having a plurality of components, and a housing surrounds at least a part of the components of the electrical filtering circuit.
