摘要(Abstract)：
本文介绍了一种测金属卤化物灯电极温度的方法,测定高温电极在三个不同波长处的辐射强度来得到电极温度。这种方法解决了因电弧辐射的干扰而造成的困难。用这个方法测量并比较了金属卤化物灯在竖直燃点时,不同镇流器工作条件时的电极温度。
In this paper we report a new method to determine the electrode temperature of metal halide lamps by measuring the electrode radiation at three different wavelengths. This method has the advantage to eliminate the interference of the arc radiation, which makes the measurement very difficult before. Using this method we attained and compared the electrode temperature at different ballasting while the lamps are vertically burning.
