“…The luminous efficacy of the popular fluorescent lamps is more than 60lm/W. The luminous efficacy of the plasma flat panel lamp reported by the Japanese and French researchers was about 30lm/W [6,7], and that of the plasma display panel (PDP) was much lower than 10lm/W [8][9][10].…”

A xenon gas discharge flat panel lamp is made and the influence factors: the gas pressures, the gas compositions and gas gap on the luminous efficacy of the xenon gas discharge flat panel lamps were investigated. Marked increments of the luminous efficacy of the lamps were observed by optimizing the structures and the discharge conditions. The results showed that the xenon gas discharge flat panel lamps with a luminance of above10,000 cd/m2, a luminous flux of above 450 lm, a size of 126×87 mm and an luminous efficacy of about 43 lm/W could be attained at about 450 torr xenon, 0.71 mm gap distance and 2.8 mm front glass layer thickness. The factors which influenced the luminous efficacy were discussed in the end.

“…In order to simplify the structure and reduce the production cost of a large BLU, intense efforts have been focused on the development of flat fluorescent lamps (FFLs) since late 1990s. [5][6][7][8][9] Both Hg 5) and Hg-free (using Xe gas) 6,10) FFLs were developed during the last decade. For the development of a large area FFL with high efficiency and low cost, it is necessary to understand the discharge phenomena inside the FFL.…”

A two-dimensional fluid simulation of Hg-Ne-Ar mixtures is developed for the study of flat fluorescent lamps (FFLs) for a backlight unit of a large-area liquid crystal display. The effects of control parameters, such as gas pressure, gap distance, driving voltage and frequency, and gas mixture ratio on discharge efficiency are investigated over the following parameter ranges: pressure of 10 -100 Torr, Hg ratio of 0.3 -2.0%, and driving voltage of 500 -2000 V with a driving frequency of 10 -100 kHz. In general, the luminance increases with driving voltage, Hg ratio, gas pressure, and the driving frequency. The luminance efficacy has optimal values for each parameter with proper steady state conditions for the enery loss mechanism and the creation and the transport of ultraviolet light.
