  • Patent number: 10658170
    Abstract: A plasma lamp includes plates that are approximately parallel, with at least one array of microcavities formed in a surface of at least one plate. When desirable, the plates are separated a fixed distance by spacers with at least one spacer being placed near the plate's edge to form a hermetic seal therewith. A gas makes contact with the microcavity array. Electrodes capable of delivering a time-varying voltage are located on the surface of each plate. At least one electrode is located on an exterior surface of at least one interior plate. Optionally, protective windows may be placed over the electrodes. The application of the time-varying voltage interacts with the gas to form a glow discharge plasma in the microcavities and the fixed volume between the plates (when present).

  • Patent number: RE45342
    Abstract: In order to achieve a discharge lamp suited to operate under reduced nominal power of e.g. 20-30 W, a lamp is proposed with two electrodes (24) arranged at a distance in a discharge vessel (20, 120) for generating an arc discharge. The discharge vessel (20,120) has a filling with a substantially free of mercury and comprises a metal halide and a rare gas. The lamp (10, 110) further comprises an outer bulb (18) arranged around the discharge vessel at a distance (d2). The outer bulb (18) is sealed and has a gas filling of a thermal conductivity (?). The inner diameter (d1) of the discharge vessel is preferably in a range from 2-2.7 mm. The wall thickness (w1) is in a range from 1.4-2 mm. A heat transition coefficient (?/d2) is calculated as thermal conductivity (?) at 800° C. of the outer bulb filling divided by the distance (d2). The so-defined heat 10 transition coefficient is below 150 W/(m2K).
