Title
(EN) PHOSPHOR-CONVERTED MONOCHROMATIC LED INCLUDING A LONG WAVELENGTH PASS FILTER CAPABLE OF EMITTING LIGHT OF WAVELENGTH OF 500 TO 700 NM
(KO) 장파장 투과필터를 포함하는 형광체 전환 단색 LED
Abstract
(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
(KO) 본 발명은 특정 구성을 가지는 장파장 투과필터를 포함하는 형광체 전환 단색 LED가 제공된다. 본 발명의 형광체 전환 단색 LED는 나노 또는 마이크로 파우더 형광체를 사용하더라도 색순도 및 효율이 매우 뛰어나다.
