金属卤化物灯按灯的结构分类
金属卤化物灯按灯的结构可分为3类：①石英电弧管内装两个主电极和一个启动电极，外面套一个硬质玻壳（有直管形和椭球形两种）的金卤灯。这类灯主要用于体育场、道路、厂房等处的普通照明。②直管形电弧管内装一对电极，不带外玻壳，可代替直管形金卤灯，用于体育场等地区泛光照明。③不带外玻壳的短弧球形金卤灯、单端或双端椭球形的金卤灯。主要用于电影放映和电影、电视的拍摄照明。
Metal halide lamps can be divided into three categories according to the structure of lamps: 1. Quartz arc tube contains two main electrodes and a starting electrode, and a hard glass shell (straight tube and ellipsoid) is coated with metal halide lamps. This kind of lamp is mainly used for general lighting of stadium, road, workshop, etc. (2) A pair of electrodes are installed in the straight tube arc tube without outer glass shell, which can replace the straight tube metal halide lamp for floodlighting in stadiums and other areas. (3) Short arc spherical metal halide lamp without external glass shell, single-end or double-end ellipsoid metal halide lamp. Mainly used for film projection and film, television shooting lighting.
