Abstract

Recent developments in metal halide technology have lead to the introduction of AC Short Arc Metal Halide lamps suitable for a wide range of illumination applications. The advantages of such sources are as follows; high brightness, small source size, high correlated color temperature, and good color quality. In addition, the efficacy of these lamps are two to three times greater than other light sources. In order to apply the AC short arc metal halide lamps properly, their physical, optical and electrical characteristics must be considered comprehensively. The metal halide arc itself is especially complex and requires careful investigation in order to make optimum optical designs. This paper will review the basics of metal halide technology and its application to lamps. Spectral and optical characteristics are discussed and optical design considerations for different applications will be reviewed. Operational requirements, including power supply characteristics and cooling will be presented. In addition, this paper will discuss present and future applications for currently available sources and possibilities for new types of metal halide lamps. Particular attention will be paid to UV radiating types.
