Document Type and Number:
WIPO Patent Application WO2003102996
Kind Code:
A3
Abstract:
A method of manufacturing partial layers on lamp bulbs, in which method functional layers are provided in thin-film technology, and which method includes at least providing a temporary layer on that region of the lamp bulb which will have no functional layer in the operational state of the lamp, subsequently providing the functional layer on the entire surface of the lamp bulb, and detaching the temporary layer together with the functional layer present thereon.
