DIMMABLE CERAMIC METAL HALIDE LAMP |
摘要 |
The invention relates to a metal halide lamp (1) comprising a ceramic discharge vessel, having an inner diameter, enclosing a discharge space which accommodate two electrodes arranged at an electrode distance, and which contains a noble gas and a salt filling, wherein (1) the salt filling comprises an alkali halide, a rare earth halide, and optionally thallium halide; (2) the discharge vessel has an aspect ratio, defined as the electrode distance divided by the inner diameter, of at maximum 4; and (3) the metal halide lamp has a wall load at full power, defined as the lamp power divided by the inner surface area of the discharge space, of at least 25 W/cm2. Especially, the discharge space contains 0.015-1.5 µg/mm3 alkali halide. |
