| 摘 要： | 本文介绍镝灯的基本工作原理、结构和特性。镝灯是一种稀土金属卤化物灯,是利用在碘化镝、碘化钬的蒸汽中放电发光而制成。它的发光效率在70流明/瓦以上,色温为6000K左右,目前使用寿命可达200小时以上。已在照相制版中试验应用。与碳精灯相比较,镝灯具有亮度高、体积小、电弧稳定、清洁等优点,是改进照相制版的一种新型光源。

| Abstract: | The working principle, structure and characteristics of a dysprosium iodide lamp are described. It is a vapour discharge lamp containing a mixture of dysprosium iodide and halmium iodide. With a lifetime of 200 hours, its luminous efficiency is above 70 lumen/watt and its colour temperature 6000 K. Trial applications in photoengraving show that the dysprasium-iodide lamp, as compared with the carbon-arc lamp, has the virtues of higher brightness, smaller dimensions, and greater stability and cleanness. As a new type of light source it is expected to improve the art of photoengraving. |
