  • Patent number: 7224111
    Abstract: An elongated dielectric barrier discharge lamp with outer and inner electrodes has a tube that is arranged on the lamp stand end of the discharge vessel and that surrounds the lamp stand. The tube serves to receive a seal in order to install the lamp in a process chamber in a gastight manner. Power supply of the outer electrodes is separated from the power supply for the inner electrodes coming out of the lamp stand by means of the above-mentioned tube. This makes it possible to prevent effectively parasitic discharges between the power supplies which are applied at different potentials during operation also in process chambers under negative pressure.

  • Patent number: 7122964
    Abstract: In a lamp and method for fabricating the same, an outer surface of the lamp tube is dipped into a conductive transparent solution for forming an electrode by a predetermined depth, and then the lamp tube is pulled out from the solution. Accordingly, an electrode having different profiles is formed on the outer surface of the tube body. Also, the outer surface of the lamp tube is dipped into the solution by an acute angle, and is pulled out from the solution. Therefore, a problem of a nonuniform brightness between lamps is not generated, and light utilization efficiency is much enhanced even when using a plurality of lamp in parallel connected to a power supply.
