摘要
短弧UHP灯的电极既要能耐大功率密度烧蚀又要有长寿命。采用适当的灯加电方案可以解决这个矛盾。针对菲力普UHP灯制定的专门驱动方案,提供了稳定的弧光和很好的电极耐久性。在本文,我们阐述在各种条件下电极性能的测试,并讨论基本的物理效应。
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.
