Abstract
The utility model provides a starter for an electronic long service life energy saving lamp (simply called LCS), which is composed of a time delay preheating circuit, a lamp cap cover and a lamp cap. The operating current little below the current of a lamp can be generated by the utility model, the delaying preheating to a filament can be realized, and the sputtering of cathode material can be diminished to a minimum degree when a lamp is started. The service life of the switching test of the utility model through more than 10000 times proves that no blackening and no aging of the two ends of a lamp tube, and the service life of the utility model can be increased more than 3 to 5 times longer than the lamp started by an LC series resonance of a general electronic ballast. Any electronic ballast for a fluorescent lamp started by an LC can all be added in the utility model, and the characteristic of a wide starting voltage is still reserved by an LCS starting circuit at the same time. The utility model can be used between the voltages of 150 to 250. The utility model has the advantages of stable start, no flicker, simple circuit construction, low cost, high reliability, and long service life.
Description
The utility model relates to the fluorescent lamp starting device, and particularly a kind of is the time-delay pipeline start up by preheating device of Design of Digital Ballast specially.
Fluorescent lamp has negative voltage-current characteristic, and must seal in ballast in the loop could steady operation.And the most traditional Inductive ballast of present usefulness, the useful life of this ballast is long, power consumption is high, volume is big but exist, and starts shortcomings such as flicker.Along with the develop rapidly of electronic technology, people develop the Inductive ballast that various electric ballast replaces traditional type in succession.Circulating maximum in the market is the electric ballast that has LC series resonance start-up circuit.This ballast is a serial connection electric capacity and form LC series resonance start-up circuit in load circuit.This circuit can start in 0.5 second fast, because the start-up time of circuit is very brief, filament not preheating is just lighted rapidly, caused the cathode material sputter seriously to damage filament.A large amount of studies have shown that, very easily turns black in the lamp two ends of adopting foregoing circuit to start, and the life-span of lamp also shortens 1/2~4/5 times than the lamp that Inductive ballast starter starts.
The purpose of this utility model provides a kind of energy prolonging lamp tube service life, dependable performance, and cost is low, simple and practical, and can connect the starting drive that various band LC series resonance circuit of electronic ballast use.
Technical solution of the present utility model is, long-life electronic energy-saving lamp starter is made up of time-delay preheat circuit, lamp holder lid and lamp holder, its solution is on the basis of known electric ballast, a time-delay preheat circuit that is made of starter S, capacitor C 1, C2, C3 is set in its start-up circuit, and its preheat curent is not more than the operating current of lamp.In parallel with C1 after capacitor C 2, the C3 series connection, the two ends of capacitor C 1 are connected on an end of two filaments respectively simultaneously, and the output of electric ballast is inserted at other two ends of filament respectively.Thereby replace and be connected on the middle startup electric capacity of filament in the LC series resonance start-up circuit.
The utility model is compared with LC series resonance start-up circuit has following advantage.
1, lamp tube service life is long.Show that by experiment the switch number of times of lamp can be used for weighing the life-span length of lamp.Start-up circuit, switch number of times that this LCS forms are: open 10 seconds, stopped 20 seconds, can reach 3-5 its useful life more than ten thousand times, and the life-span deficiency of the lamp that LC starts 10,000 times.
2, the LCS start-up circuit is compared with other start-up circuit, and the preheat curent of LCS approaches operating current, when playing little electric arc at the filament pre-heating two ends, is not easy to form fierce cathode material sputter, and starter and electronic component are difficult for impaired.And Inductive ballast just in contrast, and it is big current preheating, little current work.Therefore must cause cathode material sputter severity, also blackout is aging easily for starter, and the switch number of times of a starter can only reach 6000-10000 time.In addition, the electric ballast that adopts LC to start then is that the big electric current of big voltage is added on the filament simultaneously, makes filament have little time preheating and just lights rapidly, causes the cathode material sputter seriously to damage filament, thus the life-span of having reduced lamp.
3, in common electric ballast, increase the LCS start-up circuit, can improve the reliability of electric ballast greatly, increased the ability of dealing with metachromatic state (fluorescent tube does not start, the lamp tube wire short circuit) simultaneously.
4, the warm-up time of this start-up circuit can be by adjusting the size that capacitor C 2 change preheat curent, the closing time of control starter and carry out the preheating of filament.
5, the utility model can be arranged separately in the lamp holder, also can incorporate in the circuit of electric ballast, has that circuit structure is simple, cost is low, applicability is strong, characteristics such as dependable performance.
Below in conjunction with accompanying drawing the utility model is described in detail.
Fig. 1 is circuit theory diagrams of the present utility model;
Fig. 2 is a structural representation of the present utility model;
Fig. 3 is the right view of Fig. 2.
As Fig. 1, shown in Figure 2: this starter is made of time-delay preheat circuit, lamp holder lid, fluorescent tube, lamp holder.The preheat circuit of wherein delaying time is made of capacitor C 1, C2, C3 and starter S, in parallel after capacitor C 2, the C3 series connection with C1, wherein the two ends of capacitor C 1 are connected on an end of two filaments respectively, the two ends in addition of filament are attempted by the output of electric ballast respectively, are connected on the middle electric capacity of filament in its LC series resonance start-up circuit thereby get.
The operation principle of this starter is: when energising started, starter S was than the first discharge of fluorescent tube conducting, and this moment, capacitor C 2 was in parallel with C1, and the L/C1+C2 value diminishes, and resonance potential is very low, and fluorescent tube can't ignite.Be the filament pre-heating state this moment, and its preheat curent is slightly less than operating current.Through 1-2 after second, the sheet metal cooling on the starter flicks, capacitor C 2 be added on the C1 after C3 connect, make the change of L/C1+C ' value greatly (C '=(C
2, C
3)/(C
2+ C
3)), the resonance potential of this moment increases suddenly, and fluorescent tube ignites, and the fluorescent tube internal resistance after igniting will destroy the series resonance condition, and high pressure is from going out, and fluorescent tube enters steady-working state.
1 is the ordinary electronic ballast as shown in Figure 1, the 2nd, and fluorescent lamp, the 3rd, delayed startup circuit.
4 is starter wiring boards as shown in Figure 2, the 5th, and lamp holder lid, the 2nd, fluorescent tube, the 6th, two pin caps.In wherein fluorescent tube is packed four holes of lamp holder lid into, fix with clay.The lamp holder lid clings with glue with the contact-making surface of lamp holder.Wiring board is embedded between lamp holder lid and the lamp holder, the pin welding of each lead of lamp tube ends and lamp holder, and two leads weld with the two ends of the capacitor C 1 of start-up circuit respectively in addition.
