    Abstract: 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.

    Abstract: 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.
