A Lighting Mechanism for Flat Electron Emission Lamp

Discharge and photo-luminance properties of a parallel plates electron emission lighting device

“…In their studies, it was shown that, in addition to the very high energy for majority of electrons arriving anode, generation of electrons by the collision-induced ionization processes is unlikely to take place in the space near the cathode. This is consistent with the measurements based on optical emission spectroscopy (OES) [1], wherein the intensity of phosphor emissions was found to increase markedly while some spectral lines of nitrogen molecules in the discharge glow diminished gradually as the gas pressure became lower. Since the excitations of gas molecules occur usually only in a certain range of the electron energies [11], thus the OES-observations might also serve as an important complementary tool in unveiling the peculiar behavior of electrons prevailing in these extreme operation conditions and help to elucidate the details of lighting mechanism.…”

“…The experimental set-up used in this study was largely similar to those described in the previous work [1]. Briefly, the basic structure of the device consists of a cathode glass plate, a glass spacer, and an anode glass plate.…”

“…The device with its unique structure, nonetheless, is operating under conditions with extremely small pd values, where p is the gas pressure of nitrogen and d is the gap distance between the two planar electrodes. Indeed, as indicated previously, the implemented devices which gave rise to reasonable efficacies were mostly operated on the left hand side of the Paschen curve minimum [1]. Although such harsh operation conditions may appear to be a major challenge from the engineering point of view, it is, nevertheless, representing an area that is seldom explored scientifically.…”

“…Recently, flat electron emission lighting device has been proposed as a viable candidate for environment friendly planar light source with highly uniform light emission [1]. The device with its unique structure, nonetheless, is operating under conditions with extremely small pd values, where p is the gas pressure of nitrogen and d is the gap distance between the two planar electrodes.…”
