Abstract
Coating systems suitable for use in generating fluorescent visible light, and lamps provided with such coating systems. The coating systems includes a phosphor-containing coating that contains at least a first phosphor that is predominantly excited by ultraviolet radiation of a first wavelength to emit visible light and absorbs but is less efficiently excited by ultraviolet radiation of a second wavelength. The coating system further includes a second phosphor that absorbs the ultraviolet radiation of the second wavelength and little if any of the ultraviolet radiation of the first wavelength.
