Abstract
A lighting device with at least one first-element that emits visible light at a wavelength and irradiance sufficient to inactivate one or more pathogenic bacterial species, and at least one second element that emits light of one or more longer wave-lengths to that of the first-element. The at least one second element has a higher illuminance than that of the at least one inactivating element or component.
Claims30
A lighting device with at least one first-element that emits visible light at a wavelength and irradiance sufficient to inactivate one or more pathogenic bacterial species, and at least one second element that emits light of one or more longer wavelengths to that of the first-element, wherein the at least one second element has a higher illuminance than that of the at least one first element.
A lighting device with at least one first-element that emits visible light at a wavelength and intensity sufficient to inactivate one or more pathogenic bacterial species, and at least one second-element that emits light of one or more different wavelengths to that of the first-element, wherein the at least one first, bacteria inactivating, element and at least one second element are such that the combined output of the light source is white or a shade of white.
A lighting device with at least one first-element that emits visible light at a wavelength and intensity sufficient to inactivate one or more pathogenic bacterial species in the air and on contact surfaces and materials, and at least one second-element that emits light of different wavelengths to that of the first-element, wherein the at least one first element is operable in a first mode to emit light having an irradiance in a first range, and in a second mode to emit light having an irradiance in a second, different range.
A lighting device with at least one first-element that emits visible light at a wavelength and intensity sufficient to inactivate one or more pathogenic bacterial species, and at least one second-element that emits light of different wavelengths to that of the first-element, wherein the at least one second element is operable to provide environmental illumination.
