High-efficiency energy-saving cold cathode lamp

Abstract

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.

Description

technical field [0001] The invention relates to a novel high-efficiency electro-optical conversion technology, which belongs to the electric light source industry of metal processing, glass processing and electronic circuit design. Background technique [0002] At present, the working principle of ordinary energy-saving lamps on the market is that when the lamp filament is heated to a temperature of 1160K by a ballast, the filament starts to emit electrons (because some electronic powder is coated on the filament), and the electrons collide with argon atoms to produce inelastic collisions. After the atoms collide, they gain energy and hit the mercury atoms. After absorbing the energy, the mercury atoms transition to generate ionization and emit 253.7nm ultraviolet rays, which excite the phosphor to emit light. An energy-saving lamp tube contains an average of 5 mg of mercury. Due to the physical properties of the filament, its service life is limited to 5,000 hours, and beca...
