DEVICE FOR PRODUCING GAS DISCHARGES, CONSTRUCTED ACCORDING TO THE DIALECTRICALLY IMPEDED DISCHARGE PRINCIPLE, FOR LIGHT SOURCES AND VISUAL DISPLAY DEVICES

摘要

The invention relates to a device for producing gas discharges, which is constructed from dialectrically impeded discharges and used in the light source industry, particularly for gas discharge light sources and for visual display devices, especially for plasma visual display devices. The novel device is characterized in that at least one layer is arranged in at least one gas chamber (5) of the discharge cells between the electrodes (1) and (3), said layer consisting of single bodies (6, 6a) or joined bodies or connected formations (6b) made of dialectrical material, whereby the bodies or connected formations are integrated into the discharge. The ignition voltage decreases significantly as the thickness of the gas chamber decreases in the direction of the electrodes. This enables lower operating voltages to be used, causing a decrease in the costs and complexity of supplying power. The free surfaces facing the gas chamber are covered with a plasma so that the transformation of UV / VUV rays into visible light is more effective should the bodies or connected formations be provided with dialectrical material comprising fluorescent material or if they consist of fluorescent material. The introduction of bodies or connected formations made of dialectrical material into the gas chamber significantly reduces the volume of gas, so that the amount of gas required for a fill is reduced accordingly.
