Embodiment Construction
[0071] The inventors of the present invention have devoted research to solving the above-mentioned problems encountered in developing a practical FFL. As a result of the research, the inventors of the present invention found that the basic outline of the xenon discharge involved in the operation of the FFL is related to two separate circuits. These are (a) a drive circuit directly connected to drive electrodes outside the xenon chamber; and (b) an internal circuit formed within the xenon chamber. The two circuits are independent of each other in the flow of electrons.
[0072] Due to our limited knowledge, the internal circuitry of the FFL has not been discussed so far. Therefore, before describing the present invention, the inventors of the present invention wish to define the driving circuit and the internal circuit of the FFL. Figure 3A shows the basic principle of the driving circuit between the electrodes embedded in the insulator (7) on the glass bottom plate (2) of th...

Abstract
The invention relates to a mercury-free flat fluorescent lamp, which is composed of two separate circuits, which are a driving circuit on a bottom plate glass and an internal circuit formed in a xenon (Xe) gas chamber. The internal circuit receives electric energy from the drive circuit relying on the surface-bound charges. These surface-bound charges include polarized charges on the surface of insulating particles and ionized Xe+ and e- charges in the xenon chamber. These charges are controlled by the AC electric field of the drive circuit. induction generated. The internal circuit has electron flow between the Xe+ and e- charges respectively accumulated on the insulating particles in the xenon chamber; and the xenon discharge is generated by the mobile electrons in the xenon chamber. Under the irradiation of vacuum ultraviolet light emitted by the discharge of xenon in the xenon chamber, the fluorescent screen coated on the inner wall of the xenon chamber emits photoluminescence. A practical mercury-free flat fluorescent lamp was invented by optimizing the individual items involved in operation.
Description
technical field [0001] The present invention is a mercury-free flat fluorescent lamp (FFL), which emits light from a fluorescent screen coated on the inner surface of a glass plate in a vacuum vessel by being irradiated with vacuum ultraviolet light emitted by a discharge in a xenon (Xe) chamber. Photoluminescence (photoluminescence, PL); more precisely, the present invention is a fluorescent screen composed of fluorescent particles, which can reduce the initial lighting potential, maintenance potential, lighting delay in the dark, and the front of the fluorescent screen in the xenon chamber The resistance of moving electrons; and, the fluorescent screen of the present invention can eliminate the flicker phenomenon of xenon discharge; the present invention relates to shortening the gap between the discharge path and the fluorescent screen, to increase the ultraviolet light intensity reached on the fluorescent screen; in addition, the present invention The invention also relate...
