First Claim
Patent Images
1. A light emitting device, comprising:
- a light emitting diode to emit light having a first wavelength with a main peak in at least one wavelength range selected from ultraviolet, blue, and green wavelength ranges; and
a plurality of nanowire phosphors to convert at least a portion of light having the first wavelength emitted from the light emitting diode into light having a second wavelength longer than the first wavelength, the second wavelength having at least two main peaks in the range of visible light,wherein each of the nanowire phosphors has a length greater than the diameter, wherein the diameter is less than 1 μ

Abstract
Disclosed is a light emitting device employing nanowire phosphors. The light emitting device comprises a light emitting diode for emitting light having a first wavelength with a main peak in an ultraviolet, blue or green wavelength range; and nanowire phosphors for converting at least a portion of light having the first wavelength emitted from the light emitting diode into light with a second wavelength longer than the first wavelength. Accordingly, since the nanowire phosphors are employed, it is possible to reduce manufacturing costs of the light emitting device and to reduce light loss due to non-radiative recombination.
