Mercury-free energy-saving lamp

Abstract

The invention discloses a mercury-free energy-saving lamp, which has the following working principle that: an electrode receives current output by a controller of an electronic oscillating circuit, then the current induction activates fluorescent powder under the action of neon gas to lighten the lamp continuously, thereby achieving the purpose of transforming electrical energies into light energies. An electronic oscillating circuit is equipped according to the length and pressure of a tube, the power of the lamp and the proportion of the activated powder and gas. Because of the adoption of a way of carrying out activation by current induction, the process of heating filaments of traditional energy-saving lamps is avoided, the service life of the energy-saving lamp is doubled and redoubled, the effective service life of the energy-saving lamp can reach over 20,000 hours, the adaptation amplitude of the working voltage of the energy-saving lamp is wider, the problem of unavailable light-dimming of the common energy-saving lamps is solved, and the brightness of the mercury-free energy-saving lamp can be controlled according to the proportion of coated powder, and meet the requirement for general civil lighting.

Description

technical field [0001] The invention relates to a novel mercury-free high-efficiency conversion technology of electric energy and light energy, which belongs to the electric light source industry of metal processing, glass processing, and electronic circuit design, especially an activation method without mercury hazards. 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 (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. The ultraviolet rays excite the phosphor to emit light. Due to the physical nature of the filament, its...

Problems solved by technology

Because it adopts the method of current induction activation, it avoids the process of heating the filament of traditional energy-saving lamps, and doubles the service life of energy-saving lamps. The effective life of energy-saving lamps can reach more than 20,000 hours, and the adaptability of the working voltage It is wider, and it also solves the problem that ordinary energy-saving lamps cannot be dimmed. The brightness of mercury-free energy-saving lamps can be controlled according to the proportion of powder coating, which can meet the requirements of general civil lighting.
