Abstract (en)

[origin: WO0221559A1] The invention relates to a method for applying a coating (23) to a part of a surface of a lamp (20). The aim of the invention is to provide a simple means of applying exact coatings to parts of surfaces with complicated designs. To this end, the invention provides that the lamp is vacuum-coated. The parts of the surface of the lamp (20) that are not to be coated are covered by a mask (3) and at least one coat is applied to the non-covered parts of the surface. Said mask (3) is located at a predetermined distance (d) from the part of the surface of the lamp (20) and said mask (3) is oriented in relation to an illumination means (2) or a base (21) of the lamp (20). The invention also relates to a coated lamp that is produced according to a method of this type.
