DEFINITION

Classification: 445/11

Depositing plural coatings:

(under subclass 9) Method which includes producing or creating a plurality of deposition layers or coating on some part of the lamp or discharge device by a plurality of absorption, condensation or reaction operations.

(1) Note. Merely producing a coating upon two or more parts of the lamp or discharge device such as upon two different electrodes, where only a single coating operation is involved is not within the definition of this subclass.

(2) Note. The coatings produced in this subclass may be superposed or upon separate parts of the lamp or discharge device.

(3) Note. The coating may be of the same material applied separately or of different materials.
