发明名称 Phosphor LED
摘要 A phosphor LED for emitting light emitting diode light may include an LED designed for emitting blue primary light; and an LED phosphor designed and arranged such that it is excited by the primary light during operation and emits secondary light as a consequence, said secondary light forming at least a portion of the LED light. The LED phosphor may include a green phosphor and a red phosphor. The green phosphor and the red phosphor may be provided in a ratio such that the light emitting diode light in the CIE standard chromaticity system has a color locus in the green which is spaced apart from the Planckian locus, to be precise by at least 0.01 in terms of absolute value.

主权项 1. A phosphor light emitting diode for emitting light emitting diode light comprising: a light emitting diode designed for emitting blue primary light; and a light emitting diode phosphor designed and arranged such that it is excited by the primary light during operation and emits secondary light as a consequence, said secondary light forming at least a portion of the light emitting diode light; wherein the light emitting diode phosphor comprises a green phosphor and a red phosphor; and wherein the green phosphor and the red phosphor are provided in a ratio such that the light emitting diode light in the Commission Internationale l'Eclairage “CIE” standard chromaticity system has a color locus in the green which is spaced apart from the Planckian locus, to be precise by at least 0.01 in terms of absolute value; wherein the color locus of the light emitting diode light in the CIE standard chromaticity system lies in a quadrilateral spanned by four (x/y)-value pairs, which (x/y)-value pairs are: (0.36/0.395), (0.47/0.46), (0.38/0.52) and (0.31/0.4).
