摘要

A dielectric barrier discharge, DBD, lamp device comprises a toroid shaped discharge chamber (10) having a discharge chamber wall (12). The discharge chamber wall comprises a tubular inner wall section (14), a tubular outer wall section (16), and two ring-shaped end wall sections (18, 20). Each of the end wall sections extend between an end of the outer wall section and an end of the inner wall section. A high voltage electrode (22) is provided at an outer surface of the outer wall section of the discharge chamber wall. A low voltage electrode comprises an electrically conducting fluid surrounded by the inner wall section of the discharge chamber wall. The DBD lamp device may be part of an optical fluid treatment device.
