Description of the invention: • [Technical field to which the invention belongs]: The invention relates to an electronic ballast, and in particular to an electronic ballast having a feedback current control circuit. [Prior Art] With the development of science and technology and the improvement of living standards, lighting has become an indispensable basic requirement in daily life. In recent years, due to the global development of various types, the frequent development of commercial activities and the quality of life at home. Electricity is also increasing day by day, making the development of lighting systems that are comfortable, safe, and economical with high efficiency. Gradually, due to the advantages of high luminous efficiency, long life, and diversified light color, gas discharge lamps have become today. The mainstream of the lighting system. The emulsion discharge lamp exhibits the electrical characteristics of a negative incremental resistance and requires a ballast to maintain the current flowing through the lamp. The ballast of the gas discharge lamp must be in addition to the function of the V. The function of starting a gas discharge lamp is to provide a discharge phenomenon by using a high voltage to generate a discharge phenomenon of a free gas. - Dynamic gas discharge lamp. After the gas discharge lamp is activated, it only needs to be maintained - the smaller voltage maintains the current of the gas discharge. The traditionally used ballast is in the form of electromagnetic operation. Although the electromagnetic ballast is durable And the advantages of simple construction, but it has the disadvantages of low efficiency, large size, heavy, easy to generate noise and low frequency flicker. For modern and increasingly diversified lighting applications, electromagnetic ballasts are increasingly unable to Meet the needs of the use. Compared with the electromagnetic ballast, the electronic 1282713 ballast has excellent start-up, no flicker, high luminous efficiency and high power factor, and can save a lot of electric energy compared with the electromagnetic ballast. The ballast has gradually replaced the position of the electromagnetic ballast. The power supply used in general electronic ballasts is direct current, but the power supply currently supplied by the power system is alternating current. Therefore, most of the current use of diode full-wave rectifier circuits Or a voltage doubler rectifier circuit converts the AC power supplied by the power system and the system into DC power for use by the electronic ballast. Then the electronic ballast will generate high-frequency current at both ends of the gas discharge lamp load to ignite and maintain the light emitted by the gas discharge lamp load. However, it is currently transmitted by the power company for general household use. The quality of the mains is often not 100% stable, so the high-frequency current generated by the electronic ballast is also easy to change due to the instability of the power supply. 'So' it is easy to make the discharge of the gas discharge lamp flash. , causing the uncomfortableness of the manufacturer. H The gas discharge lamp load will age with the increase of the use time, which will gradually increase its own impedance. Thus, the current flowing through the gas discharge lamp load will decrease and decrease. The brightness that can be emitted by the gas discharge lamp load. Therefore, if the current flowing through the gas discharge lamp load can be effectively maintained so that it can be fixed at a certain value regardless of the external environmental conditions, the gas discharge lamp is negative. Money can be distributed as a stable silk, and the service life can be longer. SUMMARY OF THE INVENTION An electronic ballast for holding a gas discharge lamp load is provided to activate and maintain the primary object of the present invention. BACKGROUND OF THE INVENTION Another object of the present invention is to provide an electronic ballast for a circuit. The re-invention of the invention is to provide an electronic ballast capable of improving the discharge quality of the gas and the lifetime of the gas. ~ The more the purpose of the present invention is to provide an electronic stabilizer for the (four) unsteady power supply. In order to achieve the above object of the present invention, an electronic female benefit according to an embodiment of the present invention includes a rectifier, a starting circuit, a gate controller, a 'choke, a resonant circuit, and a constant current control circuit. The rectifying lanthanum is used to receive the AC voltage provided by the parent voltage source and rectify the AC voltage into a DC voltage for use by other components. Then, after the start-up circuit is connected to the DC voltage supplied by the rectifier 3, the operation of the closed controller is triggered, wherein the 'gate controller is used to control the switching frequency of the converter' so that the commutation II can generate different frequencies. High frequency square wave. The resonant circuit has a plurality of resonant elements, and the resonant impedance generated by the resonant elements during the action of the Wei can filter the high-frequency alternating square wave generated by the inverter, and the filtered high-frequency alternating square wave is converted into Sinusoidal current suitable for use with gas discharge lamp loads. However, since the sinusoidal current generated at both ends of the gas discharge lamp load is unstable due to some external environmental factors, the 疋 current control circuit of the present invention will detect the current flowing through the gas discharge lamp load. And using the detected current value as a basis to reciprocate the control gate controller, and then control the inverter through the gate controller to change the frequency of the high frequency side 1282713 wave generated by the inverter. Because the frequency of the million-head circuit can be changed, the resonance value can be changed, and the current value of the load of the two-body discharge lamp is changed. ^ _ 电流 The current is directly controllable, so it is also easy to fix the current value and emit the light source. ~Embedded discharge lamp load [Embodiment] The present invention is inconvenient due to external factors such as power supply quality or load aging provided by a general electronic ballast, which causes inconvenience in use. The basic concept is to install a certain current controller in the electronic stability crying to capture the current value of the load through the gas discharge lamp and to feedback the closed controller in the electronic ballast accordingly. The inter-controller can change the frequency of the high-frequency square wave output by the inverter. By controlling the frequency of the high frequency square wave, it is possible to control the current value ' flowing through the gas discharge lamp load' and fix it to a stable value. Fig. 1 is a circuit diagram showing the electronic ballast 1 符合 in accordance with the concept of the present invention. Among them, the rectifier, 1 () 4 receives the parent flow power source provided by the AC house source (10) and rectifies it into a DC power source for output for subsequent circuit components. Then, the DC voltage provided by the whole "1G4" triggers the start circuit 106 to start the controller (10) to start the action, wherein the gate control a 108 functions to control the inverter 11 to generate the switching action 'to switch the DC power to high. The frequency square wave output, so the frequency of the high frequency square wave is also controlled by the gate control 3 1G8. The resonance circuit 112 contains a plurality of resonant elements, and after providing appropriate driving, the resonant 1282713 components will resonate with each other. The action and the formation of the oscillatory impedance. The high-frequency square wave output by the inverter (4) will appear as a current close to the sine wave on both ends of the negative 胄116 after the chopping action of the spectral impedance in the resonant electric 13112 For the purpose of supplying the load 116. Since the AC voltage supplied by the AC dust source 1〇2 is usually extremely unstable under actual use conditions, the current value of the sinusoidal current across the load ΐ6 is also connected. Frequent changes often make the light source emitted by the load ΐ6 extremely unstable. In addition, with |, Α Γ 1 the current load 1 Μ increase in use time, the load 116 itself The impedance value also increases, thereby reducing the value of the current flowing through the load 116, causing the source of light emitted by the load 116 to attenuate, shortening the life of the negative «U6. Thus, in a circuit consistent with embodiments of the present invention, A constant current control circuit 114 is included for stabilizing the current value of the circulating load 116. The constant current control circuit 114 first detects the current value flowing through the load ι6 and feedback control according to the detected current value. The gate controller ι〇8. Because the frequency of the high frequency square wave output by the inverter (10) is controlled by the gate controller 1〇8, the frequency of the I high frequency square wave is related to the voltage gain of the resonance circuit 112. (10) The voltage gain of the resonant circuit 108 can be indirectly controlled by the control (4) device 1 () 8. Finally, the voltage gain of the resonant circuit 1 〇 8 in turn affects the magnitude of the current flowing through the load 116, thus dynamically adjusting the resonant circuit The voltage gain of 112 can stabilize the current value flowing through the load 116, which is the basic operating principle of the constant current control circuit. The following series of various embodiments are used to illustrate the circuit aspect that can achieve the object of the present invention. 2A is a circuit diagram of an electronic amp 1282713 aligner according to the first embodiment of the present invention. The power supply of the electronic ballast is provided by an AC voltage source age Vac. Provided by an AC voltage source Vac. The AC power source is sent to a full-wave rectifier composed of a first rectifying diode D1, a second rectifying diode 〇2, a third rectifying diode D3, and a fourth rectifying diode 〇4. After such connection, the full-wave rectifier will output a DC voltage at both ends of the full-wave rectifier, but the DC voltage is still large at this time, so a voltage-stabilizing capacitor Cdc can be connected in parallel across the full-wave rectifier for The waveform of the DC voltage outputted by the full-wave rectifier is relatively smooth. The starting circuit in this embodiment includes a starting resistor Rst, a starting capacitor Cst, and a two-terminal AC switching element (diac) Dac. The full-wave rectification into the output DC voltage produces a charging current on the starting resistor Rst, which charges the starting capacitor Cst. When starting capacitor
Cst上的充電電壓超過了一定的程度之後，會導通兩端交流 開關7L件Dac，此時，便會有啟動電流流通兩端交流開關 元件Dac。After the charging voltage on Cst exceeds a certain level, the AC switch 7L Dac at both ends is turned on. At this time, the starting current flows through the AC switching element Dac at both ends.

However, since there is another "stable component" in parallel with the first control coil CT1-1, in the embodiment, the voltage stabilizing component is composed of a third Zener diode DZ3 and a fourth Zener diode Dz4. Connected in series, so some current flows through the third Zener diode Dz3 and the fourth Zener diode Dz4 to generate a voltage that triggers the conduction of the first off element S1, and leads to the third control. The coil CTW is followed by a current flowing in the direction of the first switch-element S1. At this time, the second control coil cti_2 induces a current which flows through the parallel voltage to activate the second switching element. In this embodiment, == is connected in series with one of the first Zener diode Dz1 and a second Zener diode μ, which can provide not only the second control coil CT1_2, but also a current release path. The trigger voltage of the second switching element S2 can be stabilized. In addition, in the present embodiment, there is a fifth discharge diode M D5 帛 to limit the current generated by the second control 11 1282713 coil CT1-2 to flow back to the startup circuit. In the present embodiment, the first control coil Ctp 丨 and the second control coil CT 1-2 are designed to have opposite polarities with each other. In this way, the first switching element si and the second switching element S2 are also reverse-phase-switched to each other, and a high-frequency square wave is outputted at the series connection of the two switching elements, and the frequency of the high-frequency square wave is The switching frequency of the first switching element S1 and the second switching element S2 is determined, that is, flowing through the third Zener diode and the fourth corner body Dz4 or flowing through the first Zener diode The current magnitude of Dz丨 and the second Zener diode Dz2 is determined. After the high-frequency square wave outputted by the inverter is subjected to the resonance filtering of the resonant inductor and the resonant electric valley Cr, a voltage and a current are generated at both ends of the gas discharge lamp load, wherein the voltage and the current are high. The frequency of the frequency square wave has _, that is, the frequency of the high frequency square wave can be adjusted to the magnitude of the sinusoidal current. In addition, the impedance of the gas discharge lamp load may change with time and environment, and the current flowing through the gas discharge lamp load Lamp will also change accordingly. Therefore, it is necessary to regulate the flow through the gas discharge lamp load. The current is so large that it can be fixed at a certain value. Therefore, in the constant current control circuit of the present embodiment, there is one of the first sensing coil CT2" and the second sensing coil CT2-2 wound around the same core winding. The first sensing coil c2] is capable of detecting a current flowing through the gas discharge lamp load Lamp and sensing it to the second sensing coil CT2_2. The current induced by the first sensing coil CT2-2 passes through a sixth rectifying diode D6, a seventh rectifying diode D7', an eighth rectifying diode 12 1282713 D8, and a ninth rectifying The full-wave rectifier composed of the diode D9 is rectified into a constant current. The DC current then flows through a switching resistor R1 to generate a sensing voltage. The sense voltage is first filtered by a filter composed of a filter resistor R2 and a filter capacitor C3 to filter out noise in the voltage signal. The filtered voltage signal is used to adjust the resistance value of a variable resistance element S3. In this embodiment, the variable resistance element S3 is also implemented in one, but with the first switching element S1 and the second switching element S2. The difference is that the variable resistance element S3 operates in the ohmic region of m〇sfet, so it can be used as a variable resistor. In addition, a voltage stabilizing element for stabilizing the voltage of the trigger terminal of the variable resistive element S3 is provided in the same manner. In the present embodiment, the voltage stabilizing element is realized by a Zener diode Dz5. As described in the above, the magnitude of the current flowing through the third Zener diode and the fourth Zener diode Dz4 can be controlled to control the magnitude of the current flowing through the gas discharge lamp load Lamp, and thus the resistance of the variable resistance element S3. The value is used to control the magnitude of the current flowing through the third Zener diode Dz3 and the fourth Zener diode Dz4. As shown in the figure, the variable resistive element and the tenth rectifying diode D10, an eleventh rectifying diode DU, an eleventh whole micro-pole D12, and a thirteenth rectifying diode The dual output terminals of the full-wave rectification pirate composed of D丨3 are connected in parallel, and the dual output ends of the full-wave rectifier are connected in parallel with the two ends of the first control coil CT1-1 for controlling the flow through the second Zener The current of the polar body Dz3 and the fourth Zener diode dz4. After the constant current control circuit is connected according to the above connection mode, when the current flowing through the gas discharge lamp load Lamp is excessively large, the sensing coil CT2_2 also outputs a large current, and a larger one is generated on the conversion resistor R1. 13 1282713 Voltage 1 Then, the larger voltage causes the variable resistance element S3 to have a resistance of J. At this time, it originally flows from the first control coil cti_ 1 to the third Zener diode DZ3 and the fourth Zener. The current of the diode Dz4 has a large portion: the bypass current flows to the variable resistance element S3, causing the switching frequency of the first switching element si and the second switching element S2 to rise, thereby increasing the voltage of the resonant circuit and flowing the gas. The current of the discharge lamp load ramp drops. As such, the current flowing through the gas discharge lamp load ramp will return to the rated current. On the contrary, if the current of the gas discharge lamp is too small, the sense coil CT2-2 will also output a small current and generate a small voltage on the conversion resistor ri. Then, the smaller voltage causes the variable resistance element S3 to have a larger resistance. This day, the temple originally flows from the first control coil cti-i to the third Zener diode Dz3 and the fourth Zener diode. The body of the power w will have only a small part or even no current being bypassed to the variable resistance element S3, causing the switching frequency of the first switching element S1 and the second switching element to decrease, thereby causing the voltage gain and flow of the resonant circuit. The current through the gas discharge k load ramp rises. Thus, the current flowing through the gas discharge lamp load ramp will return to the rated current. According to the mouth, the current is controlled by the current of the third Zener diode and the fourth Zener diode DZ4, or is controlled to flow through the first Zener diode Dzl and the second Zener diode The current magnitude of the body Dz2 can indirectly control the current flowing through the gas discharge lamp load ramp. Therefore, in the circuit diagram of the second embodiment of the present invention, which is not shown in FIG. 2B, the tenth rectifying diode DIG, the tenth-rectifying diode DU, the twelfth rectifying diode 14 1282713, the body D 12 and the crucible Thirteen rectifying diodes are in the name of the surviving life> The full-wave rectifier consisting of the basket DU is connected in parallel with the second control coil molybdenum crucible. Thus, the circuit can also perform the same function as the circuit shown in Figure 2A.
