Method for formulating three-wavelength fluorescent material and three-wavelength fluorescent lamp-using fluorescent material produced by the same |
摘要 |
There is provided a method for formulating a three-wavelength fluorescent material 2 in which a blue fluorescent material B2 has a half-width value of 25 to 40 nm, a green fluorescent material has a particle diameter of 4.0 to 8.0 mu m, and the blue florescent material B2/green fluorescent material G2/red fluorescent material R1 mixing ratio is 29.2:42.0:28.8. The present invention makes it possible to improve the brightness of a three-wavelength florescent lamp 1 using this three-wavelength fluorescent material 2 by substantially 13% and the flux of light thereof by substantially 4%, thus realizing a brighter three-wavelength fluorescent lamp.
