Title:
高演色性の高効率ＬＥＤベース照明モジュール
Document Type and Number:
Japanese Patent JP5727524
Kind Code:
B2
Abstract:
An illumination module (100) includes a light mixing cavity (109) with an interior surface area (104, 106, 110) and window (108) that are physically separated from an LED (102). A portion of the window (108) is coated with a first wavelength converting material and a portion of the interior surface area (104, 106, 110) is coated with a second wavelength converting material. The window (108) may be coated with LuAG:Ce. The window (108) may also be coated with a third wavelength converting material with a peak emission wavelength between 615-655nm where the spectral response of light emitted from the window (108) is within 20% of a blackbody radiator at the same CCT. The LED (102) may emit a light that is converted by the light mixing cavity (109) with a color conversion efficiency ratio greater than 1301m/W where the light mixing cavity (109) includes two photo-luminescent materials with a peak emission wavelengths between 508- 528nm and 615-655nm.
