Abstract
An apparatus of light source includes a cathode structure, an anode structure, a fluorescent layer, a secondary electron generating layer, and a low-pressure gas layer. The fluorescent layer is located between the cathode structure and the anode structure. The low-pressure gas layer is filled between the cathode structure and the anode structure. The secondary electron generating layer is located on the cathode structure. The secondary electron generating layer can generate additional secondary electrons to hit the fluorescent layer for improving the performance of the light source.
