    • A lighting system comprises at least one excitation source (5), preferably an LED, operable to generate and radiate excitation radiation of a first wavelength (λ1); a shade (4) configured to at least in part surround the at least one source (5) and remotely located thereto; and at least one phosphor (16) provided in or on at least a part of the shade (4), wherein the phosphor (16) emits radiation of a different wavelength in response to incident excitation radiation. The phosphor can be provided on a part of an outer or inner surface of the shade. Alternatively, or in addition, the phosphor is incorporated within the shade. The lighting system finds particular application as a hanging, a desk, a floor standing, a wall mountable, a spot, an outdoor or an accent lighting fixture.
    • 照明系统包括至少一个激励源(5),优选地LED,可操作以产生和辐射第一波长(λ1)的激发辐射; 配置为至少部分地围绕所述至少一个源(5)并远程定位于其上的阴影(4) 以及至少一个设置在所述阴罩(4)的至少一部分上的荧光体(16),其中所述荧光体(16)响应入射激发辐射发射不同波长的辐射。 荧光体可以设置在阴影的外表面或内表面的一部分上。 或者,或者另外,磷光体被并入阴影中。 照明系统具有悬挂式,桌子式,落地式,壁挂式,现场,户外或重点照明装置的特殊应用。
