HYBRID INTERFERENCE COATINGS, LAMPS, AND METHODS

摘要

Disclosed herein are optical interference multilayer coatings having region provided by a physical vapor deposition process and region provided by a chemical vapor deposition process. Also disclosed herein are methods of making such coatings, as well as lamps comprising a light-transmissive envelope, at least a portion of the surface of the light-transmissive envelope being provided with the optical interference multilayer coating noted above. Such coatings, when used on lamps, may advantageously offer improved energy efficiencies for such lamps.
