Abstract
A self-cleaning window blind includes a thin layer of photocatalytic material on at least one surface of the slats. The window blind includes an ultraviolet light source which directs ultraviolet light onto the photocatalytic material. Consequently, the window blind is not dependent on available sunlight. The ultraviolet light source is located in either the headrail or the bottom rail of the window blinds. Upon exposure to ultraviolet light, organic material on the slats which may include dust, grease, or microorganisms, is converted to carbon dioxide and water. One or both of the horizontal edges of the slats may include a lip which collects water formed by the photocatalytic reaction. In some embodiments, the slats are slightly convex. This shape may inhibit water from collecting in droplets on the slat and help direct the water towards the lip. Consequently, water spots are not created on the slats.
