  • Metal halide lamp
    Patent number: 7671537
    Abstract: A metal halide lamp includes a discharge vessel surrounded by an outer envelope with clearance and has a ceramic wall which encloses a discharge space filled with a filling comprising an inert gas, such as xenon (Xe), and an ionizable salt. In the discharge space, two electrodes are arranged whose tips have a mutual interspacing so as to define a discharge path between them. The ionizable salt comprises NaI, TlI, CaI2 and X-iodide wherein X is selected from the group comprising rare earth metals.

  • High-pressure gas discharge lamp having tubular electrodes
    Patent number: 7423379
    Abstract: A high-pressure discharge lamp has a discharge vessel (10) enclosing a discharge space (11) which contains an ionizable filling. The discharge vessel has a first (2) and a second (3) mutually opposed neck-shaped portion provided with a pair of electrodes (6, 7) arranged in the discharge space (13). Each electrode is tubular over its entire length. Preferably, the electrodes are free from coils in the discharge space. Preferably, the electrodes extend to outside the discharge vessel. The high-pressure discharge lamp according to the invention is relatively easy to manufacture.
