Single-layer and laminated phosphor films were prepared by high temperature molding method with the using of green and red phosphor as raw materials,then white light emitting diode devices with three different structures(single type,green-red type and red-green type)were packaged with chip on board blue light sources.Based on fluorescence spectrophotometer system,double integral sphere system,the visible spectrum analysis system and spectral color luminance meter,the spectral reabsorption characteristics of...
-30032201type are 485K,487Kand 799 K.And the standard deviation and relative standard deviation of colortemperature in space are 173.1,172.3,284.6and 0.0373,0.052,0.066,respectively,in which the whiteLED device packaged by green-red type remote phosphor f
