  • High-pressure discharge lamp having shielding means comprised of boron nitride
    Patent number: 4479071
    Abstract: The invention relates to a high-pressure metal halide lamp in which the filling of the discharge vessel also comprises an alkali metal. The discharge vessel is surrounded by an outer envelope. One electrode of the discharge vessel is connected to a current supply conductor extending between the discharge vessel and the outer envelope. A plate-shaped element is mounted between the discharge vessel and the outer envelope in such manner that, viewed from the discharge vessel, the current supply conductor is present substantially entirely behind the plate-shaped element.According to the invention, the plate-shaped element comprises boron nitride.Increase of the arc voltage of the lamp and increase of the color temperature of the radiation emitted by the lamp is prevented in this manner.
