Abstract

The lamp has an emission part, where a pair of electrodes is arranged in the part and the part is filled with mercury and inert gas. Hermetically closing parts are formed at the ends of the emission part, where the ends lie in opposite manner. The emission part has a main emission chamber (110) and a base chamber (111) that is formed adjacent to the closing parts of the main emission chamber. The relationship V2/V1 of the interior volume V1 of the main mission area (110) and the interior volume V2 of the area (111) lies within 0,01 to 0.09.
