Abstract
PURPOSE:To improve the visibility of skin color by using a multilayered phosphor with a specified color temperature comprising bivalent europium activated blue-green phosphor with a special luminous peak, terbium activated or cerium, terbium commonly activated green phosphor and europium activated red phosphor. CONSTITUTION:A lamp color temperature is made to be in the range of 2700-3350K by using a layered phosphor comprising bivalent europium activated blue-green phosphor having a luminous peak of 470-500nm, cerium, terbium commonly-activated or terbium activated green phosphor having a luminous peak of 500-550nm, and europium activated red phosphor having a luminous peak of 600-620nm. By this arrangement, the mean and special color rendering evaluation coefficient is improved and yellowish color is corrected and so the visibility of skin color is improved.
