(EN) PURPOSE: A phosphor-converted monochromatic LED including a long wavelength pass filter is provided to prevent a droop problem and improve a temperature property and a current dependent property. CONSTITUTION: A phosphor is formed on the upper side of a blue light source and emits light of a wavelength of 500 to 700 nm by absorbing blue light emitted from the blue light source. A long wavelength pass filter is formed on the upper side of the phosphor and passes light of wavelength of 500 to 700 nm. The long wavelength pass filter includes a repetition layer on which a first thin film and a second thin film are alternatively laminated. COPYRIGHT KIPO 2012
