High-efficiency mercury-free energy-saving bulb

Abstract

The invention provides a high-efficiency mercury-free energy-saving bulb consisting of an inner bulb container and an outer bulb container, wherein the outer wall of the inner bulb container and the inner wall of the outer bulb container are provided with one conducting material adhering point, respectively, and each conducting material adhering point is provided with a metal conducting wire to be guided out; a consistent space is kept between the inner bulb container and the outer bulb container, a conducting layer and fluorescent powders are coated on the outer wall of the inner bulb container, and the conducting layer and the fluorescent powders are coated on the interior of the outer bulb container. The operating principle of the high-efficiency mercury-free energy-saving bulb is as follows: the conducting layers receive outputted current controlled by an electronic oscillation circuit to generate ionization induction, and the fluorescent powders are activated under the action of inert gas such as neon to continuously lighten a bulb body, so that a purpose of transforming electric energy into light energy is achieved. The high-efficiency mercury-free energy-saving bulb utilizes a current induction activation manner so as to avoid a process of heating a filament of the traditional energy-saving lamp and prolong the effective service life to be more than 20,000 hours; and the high-efficiency mercury-free energy-saving bulb prolongs the service life and reduces the mercury pollution although the bulb has a more complex process compared with the traditional energy-saving lamp.

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 filament of the lamp tube is heated to a temperature of 1160K by the ballast, the filament starts to emit electrons, and the electrons collide with argon atoms to produce inelastic collisions. After the argon atoms collide with energy, they collide with mercury atoms. After absorbing energy, mercury atoms transition to generate ionization, and emit 253.7nm ultraviolet rays, which excite phosphors to emit light. Due to the physical nature of the filament, its service life is limited to 5,000 hours, and because the filament generates heat when it is powered on, the conversion efficiency is low in the process of converting el...
