项目摘要

Generally mercury is used in fluorescent lamps because it provides high efficacy. The use of mercury, however, leads to difficulties in lamp ignition at low ambient temperature and also a relatively long build-up time is necessary for the lamp to reach the saturated luminance level.A mercury-free flat discharge fluorescent lamp with diagonal size ranging from 0.5 to 5.2 in has been developed. The lamps have a simple structure, with stable discharge operation and good optical characteristics have been obtained For example, a luminance of 11000cd m^<-2>, a luminous flux of 860lm, and an efficacy of 30lm W^<-1> were attained with the 444mm×27mm lamp with uniform luminance throughout the discharge volume. Although the luminous flux is sufficient for the application, the efficacy is half that of commercially available mercury fluorescent lamps. An improvement of the luminous efficacy is the most important issue for the mercury-free flat discharge fluorescent lamp. The goal of the present study is to understand the role of the gas phase kinetics in the efficacy of these mercury-free flat discharge fluorescent lamps operating under different conditions. To this end, we developed a zero-dimensional kinetic model of the positive column in Ar/Ne/Xe mixtures. Results from the model compare reasonably well with experiment and allow us to under various discharge conditions

汞通常用于荧光灯，因为它提供高效率。然而，汞的使用导致灯在低环境温度下点火困难，并且灯达到饱和亮度水平需要相对较长的建立时间。该灯结构简单，放电性能稳定，光学性能良好。444 mm × 27 mm的灯，亮度为11000 cd·m ~（-1）<-2>，光通量为860 lm，效率为30 lm·W ~<-1>（-1），在整个放电体积内亮度均匀。虽然光通量足以满足应用，但功效是市售水银荧光灯的一半。提高发光效率是无汞平板放电荧光灯的最重要的问题。本研究的目的是了解这些无汞平板放电荧光灯在不同条件下工作的效率的气相动力学的作用。为此，我们发展了零维动力学模型的正柱在Ar/Ne/氘混合物。从模型的结果比较合理，以及与实验，并允许我们在各种放电条件下
