  • Protected coating for energy efficient lamp
    Patent number: 6773141
    Abstract: A reflector lamp has a generally parabolic shaped housing (12) with an interior surface coated with a layer (14) of silver having a protective layer (16) of a stable protective oxide, such as silica, disposed thereon. An intermediate layer (18), such as a layer of elemental silicon, protects the silver layer during deposition of the silica layer and is completely or substantially consumed during formation of the silica layer. The lamp includes a light source (48) having a longitudinal axis (x) disposed on the parabolic reflector axis and preferably disposed outward of the parabolic focus (F). During lamp fabrication, the protective coating is preferably annealed to improve reflectance. The preferred lamp will have a lumens per watt greater than 14.
    Type: Grant
