<p>An electrode 3, 4, 60, 66 for a cold cathode discharge lamp 1, 64 has several parallel recesses 31 to 36, 41 to 46, 62 extending across the width of the electrode and at an angle of about 35 degrees away from the normal to its surface. The electrode 3, 4 may be formed by folding a strip of metal so that the recesses are formed between adjacent folds of the strip. Alternatively, the electrode 60, 66 may be a block of metal in which the recesses are slots 62 formed in a surface of the block. The electrode may be included in a tubular lamp 1 or in a planar lamp 64. <IMAGE></p> |
