Abstract
A method for applying a coating () to a part of a surface of a lamp (). The aim is to provide a simple manner of applying exact coatings to parts of surfaces with complicated designs. To this end, the lamp is vacuum-coated. The parts of the surface of the lamp () that are not to be coated are covered by a mask () and at least one coat is applied to the non-covered parts of the surface. The mask () is located at a predetermined distance (d) from the part of the surface of the lamp () and the mask () is oriented in relation to an illumination element () or a base () of the lamp (). The invention also relates to a coated lamp that is produced according to a method of this type.
