The invention relates to a high-efficiency energy-saving
cold cathode lamp. A lamp base of a lamp tube of the high-efficiency energy-saving
cold cathode lamp is slightly thicker than the lamp tube and is used for installing an
electrode, the
power consumption can be reduced and the luminous efficiency is improved due to the large
electrode. The operating principle of the high-efficiency energy-saving
cold cathode lamp is as follows: a lamp core
electrode receives outputted current controlled by an
electronic oscillation circuit so that electronic
powder in the lamp core electrode is activated and
ionization induction generates, fluorescent
powder is activated under the action of
inert gas such as
neon so that an energy-saving lamp is continuously lightened, and a purpose of transforming
electric energy into
light energy is achieved. According to the length and the
voltage of the lamp tube, the power of the lamp and the proportion of
powder to gas of an activated object, the
electronic oscillation circuit is used in a matched way. The high-efficiency energy-saving cold
cathode lamp disclosed by the invention utilizes a current induction activation manner so that the service life of the energy-saving lamp is doubled and redoubled, the effective service life of the energy-saving lamp can be more than 20,000 hours, the application range of working
voltage is wider, the mercury consumption of the energy-saving lamp is reduced by 95% due to
neon activation, and the mercury consumption of the high-efficiency energy-saving cold
cathode lamp is below 0.5mg.
