金属卤化物灯的优点
金属卤化物灯的优点是发光效率特别高，光效高达80～120Lm/W。由于金属卤化物灯的光谱是在连续光谱的基础上迭加了密集的线状光谱，故显色指数特别高，即彩色还原性特别好，Ra可达90。另外，金属卤化物灯的色温高，可达5000～6000K，专用投影机灯可达7000～20000K。在同等亮度条件下，色温越高，人眼感觉越亮。由于材料、工艺的限制，国产金属卤化物灯寿命在8000小时。
The advantage of metal halide lamp is its high luminous efficiency, which is as high as 80 ~ 120lm / W. Because the spectrum of metal halide lamp is based on continuous spectrum with dense linear spectrum, the color rendering index is very high, that is to say, the color reducibility is very good, and the RA can reach 90. In addition, the color temperature of metal halide lamp can reach 5000 ~ 6000K, and the special projector lamp can reach 7000 ~ 20000 K. Under the same brightness conditions, the higher the color temperature is, the brighter the human eyes feel. Due to the limitation of material and technology, the service life of domestic metal halide lamp is 8000 hours.
