Abstract: A fan assembly includes an electric motor, a rotor driven by the electric motor to rotate about an axis of rotation, and a plurality of blades, for example airfoil shaped blades, attached to the rotor. At least one blade includes a lighting assembly having an ultraviolet light source mounted inside an internal cavity proximal to an end of a blade body of the at least one blade such that the outer shape of the blade is generally unchanged by the lighting assembly.
