短弧UHP灯的电极首当其冲地将高功率密度与长寿命结合在一起。这种冲突可以通过灯的适当电气操作来解决。飞利浦UHP灯的特殊驱动方案提供了稳定的弧光连接和卓越的电极耐用性。在本文中,我们介绍了在不同条件下的电极性能测量,并讨论了潜在的物理效应。
The electrodes of short arc UHP lamps bear the brunt to combine high power densities with long life. This conflict can be resolved by a proper electrical operation of the lamp. Special drive schemes for Philips UHP lamps provide a stable arc attachment and a superior electrode durability. In this paper, we present electrode performance measurements under various conditions and discuss the underlying physical effects.
