DISCHARGE LAMP, TUBE FOR THE DISCHARGE LAMP AND METHOD OF MANUFACTURING THEREOF

摘要

The present invention provides a discharge lamp, a tube for the discharge lamp, a method of manufacturing the tube and a method of manufacturing the discharge lamp. The discharge lamp comprises: a tube(310)comprising a first twisted part(311)which has a first twist axis (1),and a base(320)having a central axis (2), the tube(310)being connected to the base(320)along the central axis (2),wherein the angle between the first twist axis (1) and the central axis (2) of the base is in the range [45°, 90°]. Thus, high flexibility for shaping the twisted tube for the discharge lamp is provided. Preferably, the shape of the tube is spherical so as to provide a homogenous light distribution. The tube preferably further comprises a second twisted part which has a second twist axis (1'); the first axis (1) and the second axis (1') do not overlap,and the second twisted part of the tube is communicatively connected with the first twisted part of the tube.
