LAMP FOR INCANDESCENT-LIKE COLOR QUALITY |
摘要 |
A low pressure discharge lamp comprises a phosphor composition configured to provide a total light emission having characteristics within specified parameters, including color point above or substantially on the Planckian locus in the CIE standard chromaticity diagram; CCT of from about 2500 kelvin to about 3600 kelvin; general color rendering index Ra(8) of at least about 80; and special color rendering index R′a(14) of from about 72 to about 87. These novel lamps result in incandescent-like color quality while also having favorable efficacy. Also disclosed are phosphor blends which enable the achievement of such lamps. |
