A small diameter xenon fluorescent lamp that is suitable for LCD backlighting has been developed. It consists of one inner electrode and one outer electrode. A pulsed current flows when a rectangular wave voltage is applied between these electrodes.
The positive column is diffused at lower operating frequency and lower wattage, and is contracted at higher operating frequency and higher wattage. When the positive column is diffused, the light output becomes stable and the VUV radiation and phosphor emission become stronger. The luminous efficiency of this lamp was about 60% of that of a conventional Hg-type cold cathode fluorescent lamp.
