Title: PHOSPHOR FILM AND LIGHT SOURCE APPARATUS
Abstract:
Provided are: a phosphor film in which the heat dissipation performance and the light utilization efficiency of the phosphor film are taken into consideration; and a light source apparatus employing the same. The phosphor film is constituted of a sintered body phase of phosphor and alumina and an air phase; the air phase content is 5 to 20% by volume in terms of the proportion of the volume of the entire film of the phosphor film; the sintered body phase content is 80 to 95% by volume in terms of the proportion of the volume of the entire film of the phosphor film; and, in the sintered body phase, the phosphor content is 40 to 85% by volume in terms of the proportion of the volume of the entire film of the phosphor film, and the alumina content is 10 to 45% by volume in terms of the proportion of the volume of the entire film of the phosphor film.
