The present invention relates to a kind of circuit that is used for fluorescent lamp (electricity-saving lamp).
Background technology
Fluorescent lamp mainly is made up of electric ballast, fluorescent tube, working of plastics, lamp holder etc. at present, and prevailing price is high, useful life is short.
A lot of in the market electricity-saving lamps all are " one open promptly bright ", and without " cold start-up " of preheating, switch life has only about 5000 times.People are for the light efficiency that improves fluorescent tube and prolong its useful life; A large amount of deep research work aspect match appliance, have been done; Comprise the selection of ballast circuit topology and the selection of cathode preheat mode etc.; Be complementary with corresponding power saving fluorescent lamps in the hope of electronic device, the purpose that reaches the light efficiency of giving full play to fluorescent tube and prolong the electricity-saving lamp life-span, but eventually because of change is big, cost is higher, complicated circuit is difficult to carry out.
Such as " a kind of improved electronic energy-saving lamp circuit " (patent No. is 200810220209.3); Though there is the prolongation effect in the life-span to fluorescent tube; But changed the internal structure (electrode that requires fluorescent tube is the T type) of fluorescent tube; Practical operation is got up quite difficult, and the cost of promoting the use of is too high, and the heating of electron plate self is not changed.
For another example " a kind of ultralong longevity high-power energy-saving lamp " (patent No. is 200810236111.7) also only be to the power saving fluorescent lamps inner cathode the composition, viscosity, proportion etc. of use electronics powder slurry slightly adjust; The electricity-saving lamp life-time dilatation is also only limited to the control of production process and the raising of production technology; The change of matter does not take place in the electricity-saving lamp life-time dilatation, and its invention only is suitable for high-power energy-saving lamp.
Summary of the invention
For the defective that price is high, useful life is short that overcomes known fluorescent lamp (electricity-saving lamp) circuit, the present invention provides a kind of fluorescent lamp circuit with long service life and low power consumption, low, the long service life of this fluorescent lamp circuit with long service life and low power consumption price.
Technical scheme of the present invention is: this circuit comprises power supply; Power supply links to each other with rectification circuit; Rectification circuit links to each other with oscillating circuit, and an end of a negative electrode in output of oscillating circuit and the fluorescent tube links to each other, and an end of another negative electrode in another output of oscillating circuit and the fluorescent tube links to each other; Be in series with delay switch (a kind of miniature time-delay normally closed switch, delay time about 1-2 second) and pressure sensitive switch between the other end of a negative electrode in the fluorescent tube and the other end of another negative electrode in the fluorescent tube.
Be in series with electric capacity between the other end of described pressure sensitive switch and negative electrode.
Be in series with electric capacity between the other end of described two negative electrodes.
Described delay switch can replace thermistor.
With pressure sensitive switch (a kind of miniature normal open switch) and delay switch (a kind of miniature time-delay normally closed switch; Delay time about 1-2 second) series connection uses or with pressure sensitive switch (a kind of miniature normal open switch) use (according to the electricity-saving lamp needs, pressure sensitive switch needs be complementary with PTC or the pressure sensitive switch need be complementary with delay switch) of connect with the PTC thermistor.
When electricity-saving lamp starts; The pressure sensitive switch rapid closing; Make electric current through the normally closed switch of delaying time (or PTC thermistor) and make its operate as normal, after time-delay normally closed switch time-delay 1-2 second (or the PTC thermistor reaches Curie temperature) lights the electricity-saving lamp preheating, pressure sensitive switch will break off rapidly; Thereby make time-delay normally closed switch (or PTC thermistor) no longer flow through electric current, so not only realized the purpose of lighting behind the first preheating fluorescent tube but also reduced the purpose of electricity-saving lamp negative electrode and PTC power consumption.Be that first preheating fluorescent tube refires, guaranteed the tube cathode emitting material, thereby prolonged the useful life of fluorescent tube not by serious sputter (because the not anti-bombardment of cathode electronics powder itself, the excessive fluorescent tube that causes easily of sputter is yellow black, has a strong impact on lamp tube service life); After fluorescent tube is lighted, cut off cathode current, (power consumption of filament is about 0.5W-1W thereby reduced the energy consumption of filament itself and PTC thermistor; The PTC power consumption is about 0.5W-1.5W); Because delay switch (or PTC) no longer includes electric current and passes through, self just can not generate heat, thereby greatly reduces the temperature in the electricity-saving lamp housing; Reach the purpose that guarantees the electronic component steady operation, prolonged the useful life of electron plate indirectly.The life-span of fluorescent tube and electron plate has all prolonged, and the life-span of whole electricity-saving lamp has also just prolonged naturally.
Under the prerequisite that does not change existing electronic component structure, existing lighting tube structure, existing production technology; With reference to the requirement of starting about cathode preheat in fluorescent lamp IEC standard and China GB standard; Both reached the purpose of cathode preheat; Reach the purpose that cuts down the consumption of energy (electricity-saving lamp starting back cuts off cathode current) again, the useful life that had promptly not only prolonged the useful life of fluorescent tube but also prolonged electronic component, (temperature of electricity-saving lamp housing reduced, and has effectively guaranteed the job stability of electronic component; Prolonged its useful life), thus the useful life of having improved electricity-saving lamp.And the present invention's (electricity-saving lamp, straight pipe type fluorescent lamp of being suitable for high or low power) applied widely, the former device of increase is with low cost, the life-span is long, reliability is high, very easily popularizes.
To solve the PTC thermistor continuous high temperature short problem of life-span of work down; With solve the too high target of electricity-saving lamp cathode temperature greatly damage problem; Continue to cause very big damage problem (to have electric current to pass through filament all the time to solve the electricity-saving lamp negative electrode through high electric current target; Form emission current therefrom; Shortened the useful life of negative electrode,, finally will damage fluorescent tube and electric ballast) if negative electrode is in the pipeline start up by preheating state for a long time; Reduce the temperature under other electronic component operational environment so that its work more stable, reliable, the life-span is longer (temperature in the electric ballast shell raises, can cause other electron component particularly transistor damage with electrolytic capacitor, make the failure rate rising.Through test, the temperature of the present invention in 18W electric energy-saving lamp housing reduces by 3～5 ℃, thereby reduced the cause thermal damage rate of transistor and electrolytic capacitor, improved the reliability of whole lamp).
Its switch number of times of the reasonable electricity-saving lamp of quality control (closed, opened in 20 seconds) about 10000 times in 40 seconds at present, and the long some life-span is about 8000 hours.Through test, same electricity-saving lamp, adopt the present invention's test to show: opening and jumping the life-span is original 3 times, and be original 2 times useful life.Do not adopt this method; PTC thermistor continuous firing, the high temperature about 70 ℃-100 ℃ is kept on the surface always, self reliability decrease; Circuit board temperature in housing is raise; Be in the electronic component lost of life under the condition of high temperature, increase the failure rate of whole lamp, thereby shortened electricity-saving lamp useful life greatly.
Advantage of the present invention: prolong electricity-saving lamp useful life, reduce power consumption, increase lumen.The one, in the useful life of direct prolonging lamp tube, another is the useful life that prolongs electron plate.
