Abstract :
The effect of patterned electrodes in Hg-free flat fluorescent lamps is investigated by using 3-D fluid simulations. The visualization of Xe*(3p1) density profiles is important to observe the efficiency dependence on the 3-D electrode shapes. The luminous efficiency of the patterned-electrode models increases about 20% as compared with that of the reference model because of the reduction of power consumption.
