ABSTRACT:
Color correction means for flash lamp are disclosed which utilizes a blue emitting organic phosphor medium to increase the total light output being emitted from the flash lamp and lower the Spectral Distribution Index (SDI) of the lamp-phosphor combination. The phosphor medium can be employed as a coating for the light-transmitting envelope of the flash lamp wherein the phosphor constituent is dissolved in a transparent film forming polymer. In certain preferred embodiments, further color correction of the flash lamp radiation can be effected with dyes incorporated into the protective cover means or containment lacquer now commonly employed.
