Abstract
A ceramic burner, a ceramic metal halide lamp, and a method of sealing the ceramic burner is provided. The ceramic burner comprises a discharge vessel enclosing a discharge space that is provided with an ionizable filling comprising one or more halides. The discharge vessel comprises a ceramic wall arranged between a first and a second end portion. The first and the second end portion are arranged such that current supply conductors are passed through the end portions to respective electrodes arranged in the discharge space for maintaining a discharge. The ceramic wall of the discharge vessel comprises a tube for introducing the ionizable filling into the discharge vessel during manufacture of the ceramic burner. The tube projects from the ceramic wall and is provided with a gastight seal. The effect of using the tube is that it enables the gastight seal to be arranged away from the ceramic wall of the discharge vessel at a projecting end of the tube.
