Light emitting device

Abstract

According to the present invention, there is provided a light emitting device, which comprises at least one laser diode configured to emit light in at least one first wavelength region selected from spectrum regions including ultraviolet ray, blue light and green light; and a light emitting material for emitting light in a second wavelength region by the light in the first wavelength region emitted from the laser diode, the second wavelength region being different from the first wavelength region, wherein a color-mixed light is made by the light in the first wavelength region and the light in the second wavelength region. Since the laser diode having strong straightness is used as a light emission source, the color-mixed light implemented by the light emitting device of the present invention has strong straightness, so that it may be effectively used for long-distance illumination and flash.
