We invented a double hollow electrode lamp (DHEL), applied an electron oscillation effect and measured its I-V curve in dc driving to evaluate the electrical characteristics. The volume discharge of this lamp showed an abnormal glow characteristic. Based on these results, we made a 9-channel flat panel lamp and confirmed the possibility of a parallel operation. In order to evaluate the enhanced performance of the DHEL, we compared it with a single hollow triode lamp and a diode lamp (DL). We measured the breakdown voltage, tube current and IR intensity of these three types of lamps. The DHEL showed the lowest breakdown voltage among the three lamps and a higher tube current than that of the DL. The IR intensity of the DHEL was more efficient than that of the DL; the enhanced quantity of efficiency was 11.8% at 0.922 W.
