Abstract (en)

[origin: EP0871203A2] A noble gas discharge lamp of the present invention comprises an outer enclosure (1A) comprising a light emitting layer (2) formed therein, and a pair of outer electrodes (5, 6) having tape shapes comprising a metal, which are positioned to the entire length of the outside of the outer enclosure (1A) so as to separate one outer electrode (5) and the other outer electrode (6) at a certain distance, and to form a first opening portion (7) and a second opening portion (8); wherein a nonlinear portion (5A, 5B, 5C) is formed at one side portion (5b) of one outer electrode (5) forming the second opening portion (8), and other side portion (6b) being opposite to the nonlinear portion(5A, 5B, 5C), is formed linearly. <IMAGE>
