介绍了一种应用于新型液晶显示器的窄带近紫外背光源。光源是脉冲驱动的汞-氩气低压放电灯。描述了一种灯的脉冲驱动和灯填充条件，与使用传统交流镇流器操作的相同灯相比，该灯在 365 和 254 nm 处的辐射输出比率显着增强。与相同灯在相同总输入功率的交流电下工作时的相应辐射输出功率相比，灯的脉冲操作还显示出增加了 365 nm 附近的一组跃迁的绝对辐射输出。
A narrow band near-UV backlight source with application in a new type of liquid crystal display is described. The light source is a pulse driven, mercury-argon gas, low-pressure discharge lamp. Pulse driving and lamp filling conditions are described for a lamp for which the ratio of the radiant outputs at 365 and 254 nm is enhanced considerably compared with the same lamp when it is operated with a conventional ac ballast. Pulsed operation of the lamp is shown also to increase the absolute radiant output of the group of transitions near 365 nm compared with the respective radiant output power from the same lamp when it is operated with ac with the same total input power.
