<p>A lamp having ceramics electrodes, adopting nano ceramics electrode as the tube cathode, the tube (4) is made to completely spiral and umbrella shape. The lamp comprises a spherical reflector (1) inside the whole tube (4) and a reflective ring/shade (2) surrounding the whole tube (4), to make to a both sides reflective effects inside and outside the tube (4). As a result, the light efficiency is increased by 2.2 times and the power consume is only 46% of the existing lamp.</p> |
