Abstract: Fluorescent lamp incorporates a finely divided phosphor coating of different particle sizes. The phosphor particles of the coating which are positioned next to the envelope inner surface are preferably relatively fine and are smaller than the relatively coarse particles which are positioned farther from the envelope inner surface. Such a special phosphor coating enables the total amount of coated phosphor to be considerably reduced.
Abstract translation: 荧光灯采用不同粒度的细分荧光粉涂层。 位于封套内表面附近的涂层的荧光体颗粒优选地相对较细，并且比位于离封套内表面更远的较粗的颗粒小。 这种特殊的荧光体涂层能够显着地减少涂覆的荧光体的总量。

Abstract: Color-corrected high-pressure mercury-vapor lamp provides good color rendition of illuminated objects, and especially good color rendition of flesh tones. The lamp utilizes a particular phosphor coating principally comprising a two-component blend. One of the phosphor blend components provides an emission in the shorter wavelength region of the visible spectrum peaking at from 440 nm to 470 nm, and an example of this component is a strontium chlorophosphate having an apatite structure and activated by a divalent europium. The other phosphor component provides an emission in the longer wavelength region of the visible spectrum peaking at from 605 nm to 630 nm, and an example of this phosphor component is yttrium phosphate-vanadate activated by tervalent europium. For the foregoing examples, the relative weight ratio of the one phosphor component to the other phosphor component is from 0.05:1 to 0.4:1.
Abstract translation: 色彩校正的高压汞蒸汽灯提供了照明物体的良好的颜色再现，并且特别是良好的肤色色调。 该灯采用主要包含双组分共混物的特定磷光体涂层。 荧光体共混物组分之一提供在440nm至470nm峰值的可见光谱的较短波长区域中的发射，并且该组分的实例是具有磷灰石结构并由二价铕激活的氯磷酸锶。 另一种荧光体组分在可见光谱的较长波长区域提供峰值峰值在605nm至630nm的发射，并且该荧光体组分的实例是由三价铕激活的磷酸钇钒酸盐。 对于前述实施例，一种荧光体组分与另一种荧光体组分的相对重量比为0.05:1至0.4:1。
