Efficient cold cathode energy-saving bulb

Abstract

The invention provides a novel efficient cold cathode energy-saving bulb. An efficient cold cathode energy-saving bulb is composed of an inner lamp liner and an outer lamp liner, wherein an electrode tube is sintered at the center of the inner lamp liner and is used for mounting a central electrode; an annular electrode is arranged between the inner lamp liner and the outer lamp liner; a consistent space is kept between the inner lamp liner and the outer lamp liner; the annular electrode is educed by a metal lead; fluorescent powder is coated on an outer wall of the inner lamp liner; and the fluorescent powder is also coated on the interior of the outer lamp liner. According to a working principle of the efficient cold cathode energy-saving bulb, a current controlled and outputted by an electronic oscillating circuit is simultaneously received by the central electrode and the annular electrode; the electronic powder in a wick electrode is activated; an ionization induction is generated; and the fluorescent powder is activated for continuously lightening an energy-saving lamp under an action of the inert gases such as, neon and the like, so that the purpose of converting electric energy into light energy is achieved.

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...
