Abstract:
1. A light emitting device, comprising: at least three light emitting diodes having different peak emission wavelengths to emit primary light in a blue, green, or red wavelength range; a molded part encapsulating the at least three light emitting diodes; and a wavelength-converter to convert the primary light into secondary light in a visible light wavelength range, the wavelength-converter being disposed in the molded part, wherein the wavelength-converter comprises a mixture of phosphors comprising a first phosphor to emit blue light, a second phosphor to emit green to yellow light, and a third phosphor to emit yellow to red light, wherein the wavelength converter comprises the first phosphor comprising a peak emission wavelength between 450 and 520 nm, the second phosphor comprising a peak emission wavelength between 500 and 570 nm, the third phosphor comprising a peak emission wavelength between 570 and 680 nm, and mixtures thereof, and wherein each phosphor comprises more than one phosphor component, each phosphor component comprising a different peak emission wavelength in the corresponding wavelength range.
