Description

Electronic starter of fluorescent lamps

The present invention relates to an electronic starter of a fluorescent lamp, and in particular, by using the principle of charging and discharging the capacitor to perform the re-lighting and return lighting of the fluorescent lamp, to prevent overheating, to exhibit the ideal function for the efficiency and lighting of the fluorescent lamp and to produce the product The present invention relates to an electronic starter of a fluorescent lamp which can reduce costs and is used to light a fluorescent lamp which is one of low pressure mercury discharge lamps.

In general, a fluorescent lamp is a kind of low pressure mercury vapor discharge lamp that generates and irradiates visible light having a predetermined wavelength by discharge of a fluorescent material applied to an inner surface of a glass tube. The fluorescent lamp has a long life of about 5 to 6 times longer than an incandescent light bulb and has a low power consumption of about one third, and thus is widely used to illuminate a predetermined place including a home and a factory.

1 is a fluorescent lamp lighting circuit diagram for lighting a conventional fluorescent lamp.

As shown in FIG. 1, the AC power source AC is connected to one terminal of one side filament H1 of the fluorescent lamp FL through the magnetic coil ballast L1, and the AC power source AC is connected to the fluorescent lamp ( It is connected so as to be applied to one terminal of the other filament H2 of FL, and the glow starter ST is connected between the one side filament H1 and the other terminal of the other filament H2 of the fluorescent lamp FL.

In the conventional fluorescent lamp lighting circuit configured as described above, when the AC power source AC is applied, the applied AC power source AC has one side filament H1 of the magnetic coil ballast L1 and the fluorescent lamp FL according to its phase. ), The glow starter (ST) and the other side filament (H2) of the fluorescent lamp (FL) flows sequentially or the other filament (H2), the glow starter (ST), the fluorescent lamp (FL) of the fluorescent lamp (FL) One side of the filament (H1) and the magnetic coil ballast (L1) is sequentially flowed through.

Then, the glow starter ST is glow discharged to generate heat, and power is accumulated in the magnetic coil ballast L1, and one filament H1 and the other filament H2 of the fluorescent lamp FL are preheated. It begins to be.

The glow starter ST is made of a bimetal switch, and the bimetal switch is connected as the glow starter ST is glow discharged to generate heat. As the bimetal switch of the glow starter ST is connected, a large amount of current flows in one side filament H1 and the other side filament H2 of the fluorescent lamp FL to be preheated rapidly.

In addition, the glow starter ST stops glow discharge as the bimetal switch is connected, and the bimetal switch is opened again because there is no heat generated.

When the bimetal switch of the glow starter ST is opened in this manner, the power is accumulated in the magnetic coil ballast L1 between one side filament H1 and the other side filament H2 of the fluorescent lamp FL. Since the discharge start voltage or more of the fluorescent lamp FL is applied, the fluorescent lamp FL starts to discharge and is turned on.

When the fluorescent lamp FL starts to discharge and is turned on, the voltage between the one side of the filament H1 and the other filament H2 of the fluorescent lamp FL is lowered so that the glow starter ST no longer glow discharges. The fluorescent lamp FL continues to be lit.

The conventional lighting circuit of the fluorescent lamp is very simple and inexpensive to manufacture the circuit, while the glow starter ST is glow discharged and the bimetal switch is connected and then opened again to open the fluorescent lamp FL. It takes about 5 ?? 7 seconds to turn on, and there is a problem that the lighting state is unstable.

Recently, various electronic starters for lighting fluorescent lamps electronically have been proposed and used.

Conventional electronic starters for lighting fluorescent lamps include U.S. Patent Nos. 4,513,227, U.S. Patent 4,749,909, U.S. Patent 2,629,944, Japanese Patent Publication No. 52-4672, Japanese Patent Publication No. 52-18078, and Japanese Patent Japanese Patent Application Publication No. 52-19481, Japanese Patent Publication No. 54-584, and British Patent No. 159,225 are known.

According to the conventional technique described above, a lighting pulse signal is generated using an RC time constant circuit to power switching elements such as transistors, SCRs, and triacs, and the generated lighting pulse signal is applied to a fluorescent lamp to light it.

However, the above-described conventional technique is not only complicated in circuit configuration, but also does not apply the lighting pulse signal again when the lighting signal is not turned on by applying a lighting pulse signal to the fluorescent lamp. Since the power switch to be turned on again (ON) there was a problem that gives a user a lot of trouble and inconvenience.

At the end of the lifetime of the fluorescent lamp, there is a lack of a configuration in which the fluorescent lamp is turned on again when the fluorescent lamp abnormally operates due to the change in the protection device of the switching element and the power supply voltage.

In addition, the lighting pulse voltage of the fluorescent lamp should be generated at the peak point of the preheating current that preheats the filament of the fluorescent lamp, so that sufficient lighting energy will be generated. Too much preheating time in order to supply sufficient preheating current caused a lot of inconvenience to the user.

Therefore, according to the conventional lighting circuit of the fluorescent lamp, it is too expensive compared to the lighting circuit using the glow starter (ST), the frequent occurrence of the lighting failure is not smoothly turned on and restart again, In case of the end of the life of the fluorescent lamp, the overheated state occurs due to the frequent operation of the electronic starter, and there are various problems such as a fire due to insufficient countermeasures.

The present invention is proposed to solve the above problems of the prior art, the object of the present invention is to flow the flow of the fluorescent lamp filament within a short time after full-wave rectification of the AC power in the initial AC power supply It can be preheated, and the lighting voltage of the fluorescent lamp can be lowered to extend the service life of the fluorescent lamp, and when the preheating current for preheating the filament of the fluorescent lamp is a peak point, it generates a lighting pulse to turn on the fluorescent lamp at once. To provide an electronic starter of fluorescent lamps that can be.

Another object of the present invention is to preheat the filament again when the fluorescent lamp is not lit at once, generate a lighting pulse to re-lit the fluorescent lamp, and the voltage of the AC power source after the AC power is turned off after the voltage is turned off while the fluorescent lamp is lit. To the top ?? In this case, preheat the filament again, generate a lighting pulse to light the fluorescent lamp, and prevent the risk of damage to the switching element and fire due to the continuous operation of the starter at the end of the lifetime of the fluorescent lamp. It is to provide an electronic starter, such as a fluorescent lamp, by introducing a noise terminal capacitor to reduce high frequency content (THD) and maximize efficiency.

The preheat stop controller 40 is configured such that the second resistor R2 connected to the connection point of the first resistor R1 and the third diode D3 of the preheater 30 has the unlit detector 51 and the gate of the TN22. Connected to a connection point, and connected to an anode of a silicon-controlled rectifier (SCR) of the switching unit 42, and a third resistor R3 is connected to the fluorescent lamp through the first capacitor C1. RC time constant part 41 is comprised by connecting to the other terminal of the other filament H12 of (10).

The switching unit 42 is configured by being connected to the other terminal of the other filament H12.

According to the electronic starter of the fluorescent lamp according to the present invention, the preheating unit 30 operates at the initial stage when the AC power source AC is supplied, thereby full-wave rectifying the AC power source and the one side and the other side filaments H11 and H12 of the fluorescent lamp 10. Preheat the filament, and when the set time elapses, the preheat stop controller 40 controls the preheater 30 to stop preheating of the filaments H11 and H12 of the fluorescent lamp 10. The fluorescent lamp 10 is turned on, and when the fluorescent lamp 10 is not lit, the re-lighting controller 50 stops the preheat stop controller 40 to operate the preheater 30 again. The re-lighting control unit 50 causes the filaments H11 and H12 of the fluorescent lamp 10 to be preheated and turned on, and the fluorescent lamp 10 repeatedly blinks for a predetermined time or more at the end of the life of the fluorescent lamp 10. Stops to prevent overheating.

Figure 3 (a) to Figure 3 (d) is a waveform diagram showing the operation of each part of Figure 2 when the lighting by an electronic starter of a fluorescent lamp according to the present invention.

In the electronic starter of the fluorescent lamp according to the present invention, when the AC power source AC is applied to the power supply terminals A and B as shown in FIG. 3A, the AC power source AC applied to the power source terminal A is the magnetic. It is applied to one side filament (H11) of the fluorescent lamp 10 through the coil-type ballast 20, AC power applied to the power supply terminal (B) is applied to the other filament (H12) of the fluorescent lamp 10 do.

In such a state, the AC power source AC supplied to one side filament H11 of the fluorescent lamp 10 passes through the fuse FUSE of the preheating unit 30, and the diodes D1-D4 are connected to FIG. 3B. As shown, after the full-wave rectification, a current flows through the gate of the TN22 by the unlit detection unit 51 to bring the TN22 of the preheater 30 into a conductive state.

Therefore, the AC power source AC passes through the magnetic coil ballast 20 and the one side filament H11 of the fluorescent lamp 10 and through the fuse FUSE of the preheater 30. After being applied to the radio wave rectified and flows again through the TN22 and the other filament (H12) of the fluorescent lamp 10, one side and the other filament (H11) (H12) of the fluorescent lamp 10 is preheated at a high speed, The voltage applied between one filament H11 and the other filament H12 of the fluorescent lamp 10 is variable as shown in FIG. 3C.

In this state, the preheating current flowing through the TN22 is charged in the first capacitor C1 as shown in FIG. 3D through the third resistor R3 of the RC time constant part 41 of the preheat stop controller 40. When there is no output power of the third resistor R3 at the negative period of the AC power AC, the charging power of the first capacitor C1 is discharged and applied to the gate of the thyristor SCR.

When the charging voltage becomes higher than the set voltage VT while the power is continuously charged and discharged to the first capacitor C1, since the conduction voltage or more is applied to the gate of the die thruster SCR, the die thruster SCR is turned on. It is in a state.

Then, since the gate voltage of the TN22 flows to the other filament H12 of the fluorescent lamp 10 through the thyristor SCR, a low potential is applied to the gate of the TN22 to be in a blocking state.

When the TN22 is turned off in this manner, preheating of the filaments H11 and H12 of the fluorescent lamp 10 is stopped, and a high lighting pulse signal is shown between the filaments H11 and H12 of the fluorescent lamp as shown in FIG. 3D. Is generated and the fluorescent lamp 10 is turned on.

Here, the pulsating power source full-wave rectified by the diodes D1-D4 is charged in the first capacitor C1 through the third resistor R3 of the RC time constant 41, and the first capacitor C1 of the first capacitor C1. The charging power is repeatedly discharged through the third resistor R3. In the third resistor R3, a voltage charged and discharged to the capacitor C1 triggers the thyristor SCR. The point of making the conductive state is always synchronized at the peak of the preheat current flowing to the filaments H11 and H12 of the fluorescent lamp 10.

This is because the discharge current of the first capacitor C1 flowing to the gate of the thyristor SCR is suppressed and the time point at which the current flows is closer to the peaks of the filaments H11 and H12 of the fluorescent lamp 10. to be.

Once the thyristor (SCR) is triggered and brought into a conducting state, since the charge voltage of the first capacitor (C1) continues to be in a conducting state, the TN22 continues to be cut off, and the fluorescent lamp 10 Will remain lit.

As described above, when the fluorescent lamp 10 is not lit at one time even when the fluorescent light 10 is turned on while the thyristors SCR are brought into a conductive state and the TN22 is turned off, the diodes D1-D4 are turned on. The full-wave rectified pulse current is applied to the cathode of the constant voltage zener diode ZD of the unlit detection unit 51 of the re-lighting control unit 50, so that the constant voltage zener diode ZD is in a conductive state.

Then, the pulsed power supply rectified by the diodes D1-D4 sequentially conducts the TN22 through the constant voltage zener diode ZD, the fifth resistor R5, and the second capacitor C2. The charging power of C1) is discharged at a high speed, and the thyristor SCR is cut off.

When the thyristors SCR is turned off, the TN22 is turned on again, so the filaments H11 and H12 of the fluorescent lamp 10 are preheated again, and the set time of the RC time constant 41 is elapsed. In this case, as the thyristor (SCR) is turned on, the TN22 is turned off again, and the fluorescent lamp 10 is turned on again.

As described above, when the fluorescent lamp 10 is not lit even when the fluorescent lamp 10 is re-lit, the unlit detector 51 operates to discharge the charging power of the first capacitor C1, and the thyristors SCR. TN22 is in a conductive state and the preheating of the filaments H11 and H12 of the fluorescent lamp 10 causes the fluorescent lamp 10 to be re-lit, thereby turning on the fluorescent lamp 10.

On the other hand, when the fluorescent lamp 10 is not lit even after the fluorescent lamp 10 is continuously lit again at the end of the life of the fluorescent lamp 10, each part of the circuit including the TN22 is overheated and the electronic starter of the fluorescent lamp is damaged, There is a risk of occurrence.

In order to prevent this, the present invention includes a second capacitor C2 in the non-light detection unit 51 to perform the re-lighting operation only for a time when the power is charged in the second capacitor C2, and the second capacitor When the charging is completed at (C2) and the discharge operation is performed, the re-lighting operation is no longer performed.

After the fluorescent lamp 10 is turned on, when the AC power source AC becomes lower than the sustained voltage of the fluorescent lamp 10 due to an external factor, the fluorescent lamp 10 is turned off, and the unlit detector 51 Since the charging of the second capacitor C2 is completed, the fluorescent lamp 10 is not re-lit even when the AC power supply returns to the normal voltage, so the AC power switch is turned off by turning off the power switch. After the power switch is turned on again, the fluorescent lamp 10 needs to be turned on.

In order to prevent this, in the present invention, when the fluorescent lamp 10 is turned on when the unlit detection unit 51 includes the reactivation control unit 52, the charging power of the second capacitor C2 is controlled by the reactivation control unit. Discharge is made through the resistor R4 of 52.

Therefore, when the AC power source AC is normally input again, the second capacitor C2 is charged with power and passes through the preheater 30 and the RC time constant 41 of the switching unit 42. The thyristor SCR is turned ON to turn on the return light.

4 (a) to 4 (b) are waveform diagrams showing time and pulse waveforms at the time of fluorescent lamp lighting and operation at the end of the fluorescent lamp by the electronic starter of the fluorescent lamp of the present invention.

Referring to Figure 4 (a), the experimental data (a) shows the time and the warm-up waveform when the straight slim 32W is turned on at 215V, the time between T1 and T2 is 860ms and after T2 indicates the lighting state, The instantaneous pk-pk pulse voltage at T2 is 2.600 V.

Referring to Fig. 4 (b), the experimental data (b) is an experiment of the straight slim 32W at 215V with the end of one fluorescent lamp shorted (end). The filament (H11, H12) of the fluorescent lamp 10 is an experiment to prevent overheating when disconnected and abnormally grounded.

Similarly, the T1 and T2 preheating times are 860 ms, after which the fluorescent lamp 10 is turned off while attempting to re-light for a predetermined time or more, and the pk-pk voltage is 4.280V.

Therefore, the electronic starter of the fluorescent lamp according to the present invention flows rectified AC power in the initial stage when the AC power is supplied to the filament (H11, H12) of the fluorescent lamp 10 to preheat the filament in a short time, the fluorescent lamp By lowering the lighting voltage of (10), the service life of the fluorescent lamp is extended, and when the preheating current for preheating the one side and the other filament (H11, H12) is a peak, a lighting pulse is generated to turn on the fluorescent lamp (10) at once. When the fluorescent lamp 10 is not lit at one time, the filaments H11 and H12 are preheated again, a lighting pulse is generated to re-lit the fluorescent lamp 10, and the AC power is turned on while the fluorescent lamp is lit. When the voltage of) decreases and is turned off, when the voltage of the AC power becomes normal again, the filament is preheated again, and then a lighting pulse is generated to light the fluorescent lamp 10. (Return lamp), in the case of the end of the life of the fluorescent lamp to prevent the risk of damage and fire due to the continuous operation of the electronic starter of the fluorescent lamp.

In the present invention, the preheater 30 operates at the initial stage when AC power is supplied to rectify the AC power so as to flow to the filaments H11 and H12 of the fluorescent lamp 10 to preheat it. The preheat stop controller 40 controls the preheater 30 to stop preheating of the filaments H11 and H12 and to turn on the fluorescent lamp 10, and when the fluorescent lamp 10 is not lit. The re-lighting control unit 50 stops the preheating stop control unit 40 so that the preheating unit 30 operates again, preheating and lighting the filaments H11 and H12, and at the end of the life of the fluorescent lamp 10. When the flashing is repeated for more than this set time, the re-lighting control unit 50 is stopped to prevent overheating.

In addition, the existing Field Effect Transistor (FET) method causes a problem in the durability of the switching element due to overheating when the filament of the fluorescent lamp is disconnected and grounded, but the present invention uses SCR as a gate trigger circuit, so it is a fluorescent lamp. The high-capacity 160W can be used, and the durability of the fluorescent lamp has been dramatically increased.

As described above, the electronic starter of the fluorescent lamp according to the present invention performs an ideal function for the lighting of the fluorescent lamp by performing the re-lighting and return lighting of the fluorescent lamp by using the charge and discharge principle of the capacitor, and prevent overheating, The circuit is simple and the number of parts required is simple to manufacture, and the production cost of the product is reduced, so the price is excellent.

In addition, the present invention preheats the filament of the fluorescent lamp by full-wave rectification of AC power, so the fluorescent lamp is turned on at the peak of the preheating current that preheats the filament of the fluorescent lamp using the RC time constant so that the fluorescent lamp is turned on within a short time (within 0.7 seconds). By using the high frequency removal unit, the surge noise and high frequency content (THD) generated from the power supply unit can be removed, and the efficiency of the fluorescent lamp can be maximized.
