The light emitting cover includes a body having an interior configured to cover at least a portion of the high touch surface and an exterior surface configured to be disinfected. At least an exterior portion of the body is transparent or translucent. A light emitter operably is coupled to the body for emitting a light through the exterior surface. The light exiting the exterior surface has at least a portion thereof having a wavelength in a range of 380 to 420 nanometers to disinfect the exterior surface. ## Claims ### Claim 1 A light emitting cover for an object that inactivates microorganisms safely for human exposure, the light emitting cover comprising: a flexible body comprising: a first surface configured to surround at least a portion of an object; a second surface configured to be disinfected, wherein at least a portion of the flexible body is transparent or translucent; a flexible light emitting layer disposed within the flexible body and configured to emit a light through the second surface, wherein a first portion of the light comprises a wavelength of 405 nanometers and comprises an irradiance of at least 0.01 milliWatts per centimeter squared (mW/cm2) at the second surface; and a light-converting layer configured to convert a second portion of the light to a wavelength outside a range of 380 to 420 nanometers, such that the light through the second surface is a disinfecting light safe for human exposure. ### Claim 2 (depends on 1) The light emitting cover of claim 1, wherein the light-converting layer and the flexible light emitting layer are different layers. ### Claim 3 A light emitting cover for a first surface that inactivates microorganisms safely for human exposure, the light emitting cover comprising: a flexible body configured to surround at least a portion of the first surface and comprising a second surface configured to be disinfected, wherein at least a portion of the flexible body is transparent or translucent; and a light emitting layer disposed within the flexible body and configured to emit: a first portion of light comprising: a wavelength in a range of 380 to 420 nanometers (nm); and a minimum irradiance sufficient to initiate inactivation of microorganisms on the second surface;
