Abstract
Abstract A deodorizing lamp comprises a lamp unit and a titanium oxide film coating the glass surface of the lamp unit and optionally at least one metal selected from among iron, platinum, rhodium, ruthenium, palladium, silver, copper, zinc, and manganese deposited on the surface of the titanium oxide film. A method for the production of a deodorizing lamp comprises the steps of applying a titania sol or an aqueous hydrogen peroxide solution of titania gel to the glass surface of a lamp unit, drying the applied layer of titania sol or titania gel, firing the dried layer thereby forming a titanium oxide film on the glass surface, and optionally depositing at least one metal from among iron, platinum, rhodium, ruthenium, palladium, silver, copper, zinc, and manganese on the titanium oxide film.
