| Research Abstract |
We put the transparent and electrically conductive ITO thin film together by baking outside of straight FL18SS-D Fluorescent Lamp, and enclosed the Hg-Ne mixed gas When it's turned on with Transparent Electrodes by high frequency sine wave voltage, the red negative glow appeared on the inner wall, and we got 500-600 nit in brightness by it. But we could not control well a state of the discharge, when the Lamp was turned on both along horizontal axis with inner filament electrodes and along vertical axis with outer Transparent electrodes at the same time. While the fluorescent paint was white, the Color Temperature of Lamp was not well controllable.
When it was turned on both along horizontal axis with another outer electrodes and along vertical also with Transparent Electrodes, we was able to control well the Color Temperature i.e. 4700K-2300K, but the brightness was reduced to about 200nit, because of the affect of two circuits.
