<p>LD 7248 COOL-WHITE FLUORESCENT LAMP WITH PHOSPHOR HAVING MODIFIED SPECTRAL ENERGY DISTRIBUTION TO IMPROVE LUMINOSITY THEREOF An improved cool-white fluorescent lamp utilizes a particular two-component phosphor combination exhibiting a narrow "blue" emission spectrum and a broad "yellow" emission spectrum to achieve improved luminous efficacy. In one preferred embodiment, the combination is a blended mixture of europium activated strontium chlorapatite with manganese and antimony coactivated calcium fluorapatite phosphors.</p> |
