Abstract
An apparatus of light source includes a cathode structure, an anode structure, a fluorescent 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, and has the function of electric conduction. The low-pressure gas layer has an electron mean free path, allowing most of electrons to directly impact the fluorescent layer under an operation voltage.
