Title:
白色発光装置の製造方法
Document Type and Number:
Japanese Patent JP4201167
Kind Code:
B2
Abstract:
Manufacturing a white light-emitting device comprises classifying wavelengths and luminances of lights emitted from light-emitters into ranks respectively; providing various kinds of combinations of a fluorescent material and a luminance-reducing material in accordance with the rank classification; integrating a selected light-emitter and a cover in which fluorescent material and luminance-reducing material are mixed. Manufacturing a white light-emitting device (1) comprises classifying wavelengths and luminances of lights emitted from light-emitters into ranks respectively; providing various kinds of combinations of a fluorescent material for converting the wavelength of the emitted light and a luminance-reducing material for adjusting the luminance of the light, in accordance with the rank classification of the wavelength and luminance of the light; manufacturing covers (7) in which a fluorescent material and a luminance-reducing material are mixed; selecting the light-emitter and the cover; and integrating the selected light-emitter and cover.
