ABSTRACT:
An electrode for a cold cathode discharge lamp, has several parallel recesses extending across the width of the electrode and at an angle of about 35 degrees away from the normal to its surface. The electrode may be formed by folding a strip of metal so that the recesses are formed between adjacent folds of the strip. Alternatively, the electrode may be a block of metal in which the recesses are slots formed in a surface of the block. The electrode may be included in a tubular lamp or in a planar lamp.
