Discharge lamps are widely used in lighting and display applications. One limitation of existing lamps is that they cannot electrically vary their color, except for lamps that use neon-mercury discharge tubes that the head investigator has developed. Our groupe applied this technique to a xenon-mercury discharge tube that has a pair of electrodes inside the tube and another pair outside. The resulting variable color system works by combining the radial discharge (RD) of the external electrodes with the longitudinal discharge (LD) of the internal electrodes. The former is the dielectric barrier discharge (DBD), which supplies electric power into the lamp through its glass wall. In this system, the inner surface of the lamp was coated with a mixture of two kinds of phosphors. One of these phosphors is excited by the resonance radiation of mercury and the other is excited by the vacuum ultraviolet (VUV) radiation of xenon. The luminous colors of these two phosphors die 3 from each other. The lamp is operated by a pulsed discharge so that the LD and the RD do not overlap. This report deals with experimental results in the color control of xenon-mercury fluorescent lamps. Their color changes from blue to red, from orange to green and from blue to green according to the phosphor-coating blend and the mixture ratio of LD to RD.

放电灯广泛应用于照明和显示应用中。现有灯具的一个限制是它们不能改变其颜色，除了使用首席研究人员开发的霓虹汞放电管的灯具。我们小组将这项技术应用于氙汞放电管，管内有一对电极，管外有另一对电极。所得到的可变颜色系统通过将外部电极的径向放电(RD)和内部电极的纵向放电(LD)相结合来工作。前者是介质阻挡放电(DBD)，它通过灯的玻璃墙向灯提供电力。在该系统中，灯的内表面涂覆了两种荧光粉的混合物。其中一个荧光粉由汞的共振辐射激发，另一个由氙气的真空紫外线(VUV)辐射激发。这两种荧光粉的发光颜色互不相同。灯由脉冲放电操作，使得LD和RD不重叠。本文报道了氙汞荧光灯颜色控制的实验结果。它们的颜色根据荧光粉的混合物和LD与RD的比例从蓝色到红色，从橙色到绿色，从蓝色到绿色。
