摘要: A lighting apparatus (10) comprises a light engine (12) producing ultra violet radiation. An enclosure (14) surrounds a radiation generating area of the light engine (12) to encompass the radiation. At least one wall (28) of the enclosure (14) is substantially reflective of the ultraviolet radiation. The enclosure (14) includes a replaceable top portion (30) which includes a phosphor portion (32). The phosphor portion (32) is spaced from the radiation generating area of the light engine (12) by a height of the enclosure (14).

摘要: A green-emitting phosphor is provided, which has the general formula LnxBO3: Ce3+y, Tb3+z, where Ln includes one or more lanthanide-type elements, such as Sc, Y, La, Gd, and Lu. x+y+z=1; 0≦x≦0.98; 0≦y≦0.5; and 0≦z≦0.5. The phosphor efficiently converts light in the UV/blue region of the spectrum (250-400 nm) to light of longer wavelength, with a peak emission intensity of about 545 nm. The phosphor is used alone, or in a phosphor blend for converting UV/blue light from a GaN-base light emitting diode to green or white light, respectively.
摘要翻译: 提供具有通式LnxBO3:Ce3 + y,Tb3 + z的绿色荧光体,其中Ln包括Sc,Y,La,Gd和Lu中的一种或多种镧系元素类元素。 x + y + z = 1; 0 <= x <= 0.98; 0 <= y <= 0.5; 0 <= z <= 0.5。 荧光体有效地将光谱(250-400nm)的UV /蓝色区域的光转换成较长波长的光,其峰值发射强度为约545nm。 荧光体单独使用或在用于将来自GaN基发光二极管的UV /蓝光分别转换成绿色或白色光的荧光体混合物中使用。
