摘要: A foil structure with generation of visible light using LED technology includes a carrier foil and an LED chip for generation of UV light. The LED chip is disposed on the carrier foil and is provided with a light output face for emission of the UV light. Furthermore, the foil structure includes a color reaction layer for conversion of the UV light into the visible light. The color reaction layer is disposed above the LED chip or in a manner laterally offset relative to the LED chip. The color reaction layer is provided with a structuring, so that the UV light emitted from the light output face of the LED chip is not emitted into the surroundings of the foil structure.

摘要: A light emitting device includes a first wavelength converter that contains a first phosphor that absorbs at least part of primary light radiated by a radiation source and converts the primary light absorbed into secondary light, and a second wavelength converter that contains a second phosphor that absorbs at least part of the secondary light and converts the secondary light absorbed into tertiary light. The lifetime of fluorescence emitted from the second phosphor is longer than the lifetime of fluorescence emitted from the first phosphor, and the light density of the secondary light, with which the second wavelength converter is irradiated, is lower than the light density of the primary light, with which the first wavelength converter is irradiated.
