摘　　要：白鹤梁题刻原址水下保护工程采用“无压容器”原理兴建。针对白鹤梁题刻的特点,在满足人们对题刻最佳观赏视觉的前提下,经多方案比选,最终选择LED光芯灯的照明方案。 LED光芯灯使用低压电源,在水中安全系数高。采用3 W的LED芯片,20颗安装到一个灯具中,置于题刻表面上方2~3 m处,灯具外观的前端为半球型透明罩,后端为不锈钢后盖,后盖上设有可水下插拔的水密插座,便于灯具的更换。工程于2002年2月开工兴建,2010年4月完工运行至今,实现了人们常年在水下观赏题刻的梦想,为水下文化遗产的原址保护提供了成功的工程范例。The concept of ＂non pressure vessel＂ was adopted to construct the underwater protection works of White Crane Ridge Inscription. Aiming at the characteristics of the underwater inscription and for obtaining a perfect viewing effect, the LED lamps were adopted as the lighting solution, which uses low voltage power thus possessing high safety coefficient in water. A lan-tern, arranged 2~3m above the inscription, is consisted of 20 LED chips of 3W. The lantern is equipped with hemispheric trans-parent hood in the front and a stainless steel back cover, on which, a water-sealed socket is designed for convenient lamp main-tenance. The construction of lighting system started in February 2002 and was completed in 2010, its operation has fulfilled the dream of watching the inscription underwater, providing a successful case for underwater cultural relics protection in the world.
