  • Electrodeless low-pressure discharge lamp having a cooling body with a partitioned vapor channel
    Patent number: 5355054
    Abstract: An electrodeless low-pressure discharge lamp having a sealed discharge vessel filled with a metal and a rare gas and having a cavity. An inductive device is disposed in the cavity for generating a high-frequency electric field inside the discharge vessel during lamp operation. The inductive device includes a winding of metal wire surrounding a cylindrical core of magnetizable material. A cooling body is in contact with the cylindrical core for removing heat generated in the core during lamp operation. The cooling body is closed in a gastight manner and includes a condenser, an evaporator, a liquid, and a capillary structure (T, U) which comprises a winding (U) of gauze surrounding a vapor channel (V) for transporting the liquid from the condenser to the evaporator. The capillary structure has a central partition wall (T), which divides the vapor channel in two, and is connected along two opposing longitudinal sides thereof to the gauze winding (U).
