Abstract:
1. A dielectric barrier discharge lamp, comprising a) a discharge vessel having a principal axis, the discharge vessel enclosing a discharge volume filled with a discharge gas, the discharge vessel further comprising end portions intersected by the principal axis, b) at least one electrode of a first type and at least one electrode of a second type, the electrodes of one type being energized to act as a cathode and the electrodes of other type being energized to act as an anode, the electrodes being substantially straight, elongated electrodes with a longitudinal axis substantially parallel to the principal axis of the discharge vessel, c) the electrodes being positioned within the discharge volume, d) the electrodes of at least one type being isolated from the discharge volume by a dielectric layer; and e) the electrodes of the second type arranged in a substantially hexagonal lattice and the electrodes of the first type arranged in the middle of the substantially hexagonal lattice.
