High-pressure discharge lamp. |
| 摘要 |
<p>The invention relates to a high-pressure metal halide lamps in which the filling of the discharge vessel (3) also comprises an alkali metal. The discharge vessel is surrounded by an outer envelope (2). One electrode of the discharge vessel is connected to a current supply conductor (7) extending between the discharge vessel and the outer envelope. A plate-shaped element (20) is mounted between the discharge vessel (3) and the outer envelope (2) in such manner that, viewed from the discharge vessel, the current supply conductor (7) is present substantially entirely behind the plate-shaped element.</p><p>According to the invention, the plate-shaped (20) element comprises boron nitride.</p><p>Increase of the arc voltage of the lamp and increase of the colour temperature of the radiation emitted by the lamp is prevented in this manner.</p> |
