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

Efficient cold cathode energy-saving lamp

Technical field

The present invention relates to the efficient switch technology of a kind of new type electro, belong to the electric light source industry of metal processing, glass processing, design of electronic circuits.

Background technology

The operation principle of common energy-saving lamp is when being heated to the 1160K temperature by ballast to tube filament in the market, filament begins electron emission (because being coated with some electronic powders at filament), the electron collision ar atmo produces inelastic collision, obtain energy after the ar atmo collision and clashed into again mercury atom, mercury atom transition behind absorbed energy produces ionization, send the ultraviolet ray of 253.7nm, ultraviolet ray excited light-emitting phosphor.An energy-saving lamp tube on average contains 5 milligrams mercury, is limited within 5000 hours because the physical property of filament determines its useful life, also because filament can produce heat powering up, causes at electric energy and change inefficiency in the process of transform light energy.The at present popularization of electricity-saving lamp runs into the embarrassment of mercury pollution environment.

Summary of the invention

In order to overcome the deficiency of lacking in existing electricity-saving lamp mercury pollution and useful life, the invention provides a kind of new and effective cold cathode energy-saving lamp, the lamp base of efficient cool negative electrode energy-saving lamp tube is partly slightly thick than fluorescent tube, be used for installing electrodes, processing like this is because large electrode can reduce the power consumption of lamp to improve light efficiency.Its operation principle is the electric current that wick electrode is accepted electronic oscillating circuit control output, activate the electronic powder in the wick electrode, produce the ionization induction, activated phosphor makes electricity-saving lamp continue to light under the effect of the inert gases such as neon, converts the purpose of luminous energy to reach electric energy.Length and pipe according to fluorescent tube are pressed, and the size of the power of light fixture and the ratio that activates object powder, gas, supporting electronic oscillating circuit.Because the mode that it adopts the electric current induction to activate, avoided the process of traditional energy-saving lamp with filament heating, and so that be doubled and redoubled the useful life of electricity-saving lamp, the useful life that electricity-saving lamp work is used can reach more than 20,000 hours, the amplitude of adaptation of operating voltage is wider, because activating, neon make electricity-saving lamp mercury consumption reduce 95%, the mercury consumption of efficient cold cathode energy-saving lamp is below 0.5 milligram, although on the technique more complicated than traditional energy-saving lamp, it is short-lived and reduced the problem of mercury pollution to have broken away from the common energy-saving lamp filament.Can satisfy general domestic lighting.

The invention has the beneficial effects as follows that efficient cold cathode energy-saving lamp can reduce electricity-saving lamp mercury pollution 95%, prolong the useful life of electricity-saving lamp more than 4 times, and material is purchased easily.

Description of drawings

Fig. 1 is that wherein A is the fluorescent tube part without mercury evil electricity-saving lamp, and B is for placing the cap part of electronic oscillating circuit controller;

Fig. 2 is that the internal anatomy of A among Fig. 1 is wherein 1 for the vacuum glass fluorescent tube, 2 is the limit of electric current induction in glass tube with vacuum, 3 for drawing the metallic conduction of vacuum tube, 4 is the electronic oscillating circuit controller, 5 is the plastic casing of placing the cap part of electronic oscillating circuit controller, the 6 five metals power parts for the cap part of placing the electronic oscillating circuit controller divide, and 7 is the inert gas such as neon;

Embodiment

The inert gas 7 such as filling neon after fluorescent tube vacuumizes, electronic oscillating circuit controller 4 can be exported certain electric current and voltage behind plugged, the plain conductor 3 of drawing vacuum tube by connection makes two electrodes produce the discharge induction activates vacuum glass fluorescent tube 1 vacuum tube inwall under the effect of the inert gases such as neon 7 fluorescent material in the limit 2 of electric current induction in the glass tube with vacuum, finish the conversion work of electric energy and luminous energy, make electricity-saving lamp continue to light.

Since the three primary colors fluorescent powder characteristic can occur brightness have of short duration excessively, the characteristic that the mixed inert gas such as neon 7 thermal conductivity are low, so can not resemble the so fast of common energy-saving lamp decay without mercury evil electricity-saving lamp, the limit 2 of electric current induction can not produce large heat yet in glass tube with vacuum, vacuum glass fluorescent tube 1 just can too not generate heat yet, and naturally can prolong useful life without mercury evil electricity-saving lamp.

Efficient cold cathode energy-saving lamp colour temperature is soft, and the electric light transfer ratio is high, and the life-span is long, and it is wide to be suitable for voltage, and relative cost is low, and applied range can light modulation, and the life-span is more than three times of common energy-conserving product.

Claims

1. efficient cold cathode energy-saving lamp is characterized in that: the lamp base of efficient cool negative electrode energy-saving lamp tube is partly slightly thick than fluorescent tube, is used for installing electrodes, and processing like this is because large electrode can reduce the power consumption of lamp with the raising light efficiency.
