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 phosphor in remote phoaphor film and the photochromic properties of white light emitting diode packaged were studied, and the corresponding mechanisms were analyzed then. The results showed that, the red phosphor in remote phosphor film has obvious reabsorption affection on green spectrum emitted fromgreen phosphor, and the spectral chromaticity coordinates of mobile satisfy linear equations as y=－0.881 6x+0.922 5, R2=0.998 6. Laminated film can improve the uniformity of color temperature, the difference of space color temperature of single type, greenred type and redgreen type are 485 K, 487 K and 799 K. And the standard deviation and relative standard deviation of color temperature in space are 173.1, 172.3, 284.6 and 0.0373, 0.052, 0.066, respectively, in which the white LED device packaged by greenred type remote phosphor film achieve the highest luminous efficiency of 301.1 lm·W－1 (@350 mA, 9.2 V).
