摘要： A metal halide lamp (10) includes a light-transmissive envelope (12) which encloses a metal halide pool (30) for generating a discharge when spaced apart electrodes (20, 22) within the envelope are supplied with an electric current. A multi-layer coating (40) is deposited on a surface (42) of the envelope. The coating includes several layers of at least two materials of different refractive index, which, in combination, reflect radiation in the UV region of the electromagnetic spectrum. Rather than optimizing the coating for a normal (i.e., 0°) angle of incidence on the coating, the multi-layer coating is optimized at an angle which is selected to be within 10° of the mean angle (α) of incidence of the UV radiation on the arctube surface, thereby increasing the amount of UV radiation which is returned to the metal halide pool. The coating is preferably optimized for high reflectivity in the UV-region of the spectrum and high transmission in the visible region of the spectrum to maximize useful light output while reflecting UV light back to the metal halide pool for improved heating of the pool.
摘要翻译：金属卤化物灯（10）包括透光外壳（12），其包围金属卤化物池（30），用于在外壳内的间隔开的电极（20,22）提供电流时产生放电。多层涂层（40）沉积在外壳的表面（42）上。涂层包括几层不同折射率的至少两种材料，它们组合地反射了电磁光谱的UV区域中的辐射。不是将涂层优化到涂层上的正常（即0°）入射角，而是将多层涂层以选定的角度（α）为10°以内的角度进行优化在辐射管表面上的UV辐射，从而增加返回到金属卤化物池的紫外线辐射量。该涂层优选针对光谱的UV区域中的高反射率和在光谱的可见光区域中的高透射率进行优化，以使有用的光输出最大化，同时将UV光反射回金属卤化物池，以改善池的加热。

摘要： A lighting apparatus includes a bilaterally symmetrical light engine comprising first and second light emitting diode (LED) devices or planar LED device arrays facing opposite directions, and an envelope including phosphor spaced apart from and surrounding the bilaterally symmetrical light engine. The phosphor is effective to convert light emitted by the light engine to emission light. The bilaterally symmetrical light engine may be configured to emit light having a bilaterally symmetrical intensity distribution that is uniform except at emission angles within 10° of the symmetry plane of the bilaterally symmetrical light engine. Each of the first and second LED devices or planar LED device arrays may comprise at least one hemispherically emitting LED device including an LED chip and an encapsulant encapsulating the LED chip and shaped to refract light emitted by the LED chip into a uniform distribution over a hemispherical solid angle.
