Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a fluorescent lamp lighting device and a fluorescent lamp starter device, and more particularly to a fluorescent lamp lighting device and a fluorescent lamp starter device suitable as a device for lighting a fluorescent lamp in a short time.

[0002]

2. Description of the Related Art FIG. 7 is a circuit diagram of a conventional fluorescent lamp lighting device. A conventional fluorescent lamp lighting device includes a switch 10 connected to an AC power supply, a ballast 12, and a fluorescent lamp 14.
And a series circuit of a fuse 16.
Further, the conventional fluorescent lamp lighting device includes a glow starter 18 connected in parallel with the fluorescent lamp 14, and a noise preventing capacitor 20, respectively.

FIG. 8 shows a structural diagram of a glow starter 18. The glow starter 18 includes the base 22 and the glass case 2.
4 and a fixed electrode 26 inside the package.
And a bimetal movable electrode 28. The bimetal movable electrode 28 is heated so that the fixed electrode 2
6 is bent in a direction to close the contact point with 6.

The operation of the conventional fluorescent lamp lighting device will be described below. In FIG. 7, when the switch 10 connected to the AC power supply is turned on, the glow starter 1 is turned on.
A voltage is applied between the fixed electrode 26 of FIG. As a result, a discharge is generated between the two, and the bimetal movable electrode 28 is moved by the fixed electrode 2
6 is bent in a direction to close the contact point with 6. After the switch 10 is closed, the bimetal movable electrode 28 and the fixed electrode 26 of the glow starter 18 come into contact with each other in about 2 seconds.

When the fixed electrode 26 and the bimetal movable electrode 28 come into contact with each other, current is supplied to both filaments 30 and 32 of the fluorescent lamp 14 from the AC power source through the ballast 12. The filaments 30 and 32 are preheated by the flow of the current, and are in a state of emitting thermoelectrons.

After the fixed electrode 26 and the bimetal movable electrode 28 come into contact with each other and the current starts flowing through the filaments 30 and 32, heat is hardly generated inside the glow starter 18. For this reason, the temperature of the bimetal movable electrode 28 gradually decreases, and the contact between the fixed electrode 26 and the bimetal movable electrode 28 is eventually opened. At the moment when the contacts are opened, a back electromotive force is generated in the ballast 12, and a voltage approximately twice the voltage of the AC power supply is applied between the filaments 30 and 32 of the fluorescent lamp 14. As a result, the fluorescent lamp 14 shifts to a lighting state.

While the fluorescent lamp 14 is on, the fluorescent lamp 1
A discharge current flows between the filaments 30 and 32 in the four tubes. At this time, a tube voltage lower than the operating voltage of the glow starter 18 is generated between the filaments 30 and 32. Therefore, the glow starter 18 is maintained in a non-operating state while the fluorescent lamp 14 is turned on. Thus, according to the conventional fluorescent lamp lighting device, the fluorescent lamp 14 can be reliably turned on using the glow starter 18.

[0008]

However, the conventional fluorescent lamp lighting device requires about 4 to 5 seconds to turn on the fluorescent lamp 14. When the outside air temperature is low, more time is required to bend the bimetal movable electrode 28 into a desired shape, and the lighting time of the fluorescent lamp 14 is prolonged. As described above, the conventional fluorescent lamp lighting device has a disadvantage that it takes a long lighting time to light the fluorescent lamp 14.

In the conventional fluorescent lamp lighting device, after the switch 10 is turned on, the fluorescent lamp 1 is turned on.
The glow starter 1 is moved until the light 4 is turned on.
The flashing of 8 may be repeated several times. The filaments 30 and 32 of the fluorescent lamp 14 are formed of a double coil of tungsten, and the coil is coated with an emitter made of an oxide such as barium or strontium.

The emitter scatters and evaporates due to collision with electrons and heat. The life of the fluorescent lamp 14 is reduced by the consumption of the emitter. The consumption of the emitter is promoted by repeated blinking of the glow starter 18. Therefore, in order to prolong the life of the fluorescent lamp 14, it is desirable that the glow starter does not repeat blinking for one switch-on operation. In this regard, the conventional fluorescent lamp lighting device has a drawback that it is difficult to extend the life of the fluorescent lamp 14.

Further, the conventional fluorescent lamp lighting device has a drawback that the glow starter 18 may be repeatedly turned on and off several times, so that noise is easily applied to external devices.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems, and can light a fluorescent lamp in a short lighting time, which is advantageous for prolonging the life of the fluorescent lamp, and which is advantageous in terms of external light. A first object is to provide a fluorescent lamp lighting device that does not easily give noise to equipment.

Further, the present invention provides a fluorescent lamp starter device which is compatible with a glow starter and which can replace the conventional fluorescent lamp lighting device by replacing the glow starter with the fluorescent lamp lighting device according to the present invention. The second purpose is to provide.

Embodiments of the present invention will be described below with reference to the drawings. Elements common to the drawings are denoted by the same reference numerals, and redundant description will be omitted.

Embodiment 1 (1) Detailed Description of Configuration of First Embodiment FIG. 1 is a conceptual diagram of a fluorescent lamp lighting device according to a first embodiment of the present invention. The fluorescent lamp lighting device of the present embodiment includes a switch 10 connected to an AC power supply. A ballast 12 having a choke coil is connected to the switch 10 in series.

The fluorescent lamp lighting device includes first and second sockets 34 and 36 mounted on both ends of the fluorescent lamp 14.
It has. First and second sockets 34, 36
Respectively have two connection pins 38, 40 or 42,
44. The ballast 12 is connected to one connection pin 38 of the first socket 34.

The filaments 30, 32 of the fluorescent lamp 14
Consists of a double coil of tungsten coated with an emitter. The two connection pins 38 and 40 of the first socket 34 are connected to both ends of the filament 30, respectively. On the other hand, the two connection pins 42 and 44 of the second socket 36 are connected to both ends of the filament 32, respectively.

The connection pins 40 of the first socket 34 and the second
Between the connection pin 44 of the socket 36, a lighting series circuit 50 composed of a PTC thermistor 46 and a varistor 48 connected in series is connected in parallel with the fluorescent lamp 14. The fuse 16 is connected to the other connection pin 42 of the second socket 36.

A curve shown by a solid line in FIG.
5 shows the voltage-current characteristics of FIG. In FIG. 2, the horizontal axis is voltage (V).
, And the vertical axis represents the current (A). As shown in FIG. 2, the varistor 48 has the property of changing the resistance value in a non-linear manner according to the applied voltage, and when the applied voltage exceeds a predetermined operating voltage V0, the current flows rapidly. It has the property of starting to make it.

FIG. 3 shows the time current characteristics of the positive temperature coefficient thermistor 46. In FIG. 3, the horizontal axis represents time (t), and the vertical axis represents current (A). The positive-characteristic thermistor 46 is a positive-characteristic thermistor that increases the resistance value as the temperature increases. The PCT thermistor 46 is configured by a semiconductor device having the above-described positive characteristics.

When a current flows through the positive temperature coefficient thermistor 46, its resistance value increases with an increase in temperature of the positive temperature coefficient thermistor 46, and it becomes difficult for the current to flow through the positive temperature coefficient thermistor 46. Therefore, when an AC power supply is applied to the positive temperature coefficient thermistor 46, the value of the flowing current rapidly decreases with time as shown in FIG.

(2) Detailed Operation and Operation of First Embodiment Next, the operation of the fluorescent lamp lighting device shown in FIG. 1 will be described in detail. For starting lighting of the fluorescent lamp 14, it is necessary to appropriately preheat the filaments 30 and 32 and to apply a high voltage between the filaments 30 and 32. The former has the function of activating electron emission of the cathode material and facilitating starting lighting. On the other hand, the latter has an important role of initiating discharge between the electrodes.

In the fluorescent lamp lighting device according to the present embodiment, after the switch 10 is turned on, first, the filament 3 is turned on.
A pre-heat treatment of 0.32 was performed, and then the filament 3
When 0,32 is heated to an appropriate temperature, the filament 30,
A high voltage is applied between the lamps 32 to start the fluorescent lamp 14.

That is, in the fluorescent lamp lighting device according to the present embodiment, when the switch 10 connected to the AC power supply is turned on, the voltage of the AC power supply is changed to the lighting series circuit 50.
Is applied to At this time, an initial voltage V1 indicated by a broken line in FIG. 2 is applied to the varistor 48. The initial voltage V1 is a value obtained by subtracting a voltage drop consumed by the positive temperature coefficient thermistor 46, the filaments 30, 32, the ballast 12, and the like from the voltage of the AC power supply.

In this embodiment, the operating voltage V0 of the varistor 48 is set to a value smaller than the above-mentioned initial voltage V1. Therefore, when the switch 10 is turned on, immediately after that, a current corresponding to the positive half cycle of the AC power supply passes through the ballast 2 and the filament 30 →
Positive characteristic thermistor 46 → varistor 48 → filament 3
2 → circulates through the path of the fuse 16. Next, in the negative cycle of the AC power supply, a similar current flows along the reverse path. Thus, the filaments 30, 3
The filaments 30 and 32 are preheated in the process of passing the current through the filaments 2, and a state in which the filaments 30 and 32 emit thermoelectrons is formed.

After the switch 10 is turned on, about 1
After a lapse of seconds, the temperature of the positive temperature coefficient thermistor 46 reaches an appropriate temperature due to the current flowing through the positive temperature coefficient thermistor 46 during that time. Thereafter, when a current flows through the positive characteristic thermistor 46 every half cycle of the AC power supply, the resistance value of the positive characteristic thermistor 46 rapidly increases, and as shown in FIG. 3, the current flowing through the positive characteristic thermistor 46 rapidly decreases. I do.

The energy of the current that has stopped flowing rapidly with the increase in the resistance value of the positive temperature coefficient thermistor 46 is stored in the choke coil constituting the ballast 12. And
At the time when the current flowing through the positive temperature coefficient thermistor 46 shows a sharp decrease, that is, at the time when the current flowing through the lighting series circuit 50 shows a sudden decrease, a stable state is established between the filaments 30 and 32 of the fluorescent lamp 14. Voltage corresponding to the sum of the back electromotive force generated by the heater 12 and the voltage generated by the AC power supply,
Specifically, a voltage that is approximately twice the voltage generated by the AC power supply is applied. The fluorescent lamp 14 is turned on by the application of the high voltage.

When the fluorescent lamp 14 is turned on,
A discharge current flows between the filaments 30 and 32 in the fluorescent lamp 14. At this time, the tube voltage of the fluorescent lamp 14 has a smaller value than the operating voltage V0 of the varistor 48. Therefore, while the fluorescent lamp 14 is lit, the positive temperature coefficient thermistor 46
Varistor 48 is always kept in the cut-off state regardless of the resistance value of. Therefore, during lighting of the fluorescent lamp 14, a large amount of power is not consumed by the lighting series circuit 50.

As described above, according to the fluorescent lamp lighting device of this embodiment, the pre-heat treatment of the filaments 30 and 32 can be started immediately after the switch 10 is turned on. On the other hand, in the conventional apparatus using the glow starter, the pre-heating of the filaments 30 and 32 is not started until the glow starter is appropriately heated. Therefore, according to the fluorescent lamp lighting device of the present embodiment, the preheating of the filaments 30 and 32 can be completed earlier than in the fluorescent lamp lighting device using the glow starter.

Further, according to the fluorescent lamp lighting device of the present embodiment, after the positive temperature coefficient thermistor 46 is heated to an appropriate temperature, that is, after the period necessary for preheating the filaments 30 and 32 is completed, the filament 30 is immediately turned on. , 32
A high voltage can be applied in between. On the other hand, in a conventional apparatus using a glow starter, the filament 3
Regardless of the state of 0, 32, application of a high voltage is not performed until the contact of the glow starter is opened. Therefore, according to the fluorescent lamp lighting device of the present embodiment, the filament 3
After the completion of the pre-heat treatment of 0, 32, the fluorescent lamp 14 can be turned on earlier than an apparatus using a glow starter.

As described above, according to the fluorescent lamp lighting device of the present embodiment, after the switch 10 is turned on, the preheating of the filaments 30 and 32 is immediately terminated.
After the preheating of the filaments 30 and 32 is completed, the fluorescent lamp 14 can be immediately shifted to the lighting state. For this reason, according to the fluorescent lamp lighting device of the present embodiment, the time required for starting and lighting the fluorescent lamp 14 can be sufficiently reduced as compared with a conventional device using a glow starter.

Further, according to the fluorescent lamp lighting device of the present embodiment, it is possible to surely keep the current flowing through the filaments 30 and 32 until the PTC thermistor 46 is heated to an appropriate temperature. Therefore, according to the fluorescent lamp lighting device of the present embodiment, the filaments 30 and 32 can be sufficiently preheated reliably in the process of preheating the filaments 30 and 32.

If the filaments 30 and 32 are sufficiently heated at the time when a high voltage is applied between the filaments 30 and 32, the fluorescent lamp 14 can be reliably switched to the lighting state by one high voltage application. it can. Therefore, according to the fluorescent lamp lighting device of the present embodiment, the fluorescent lamp 14 can be turned on only by executing one high voltage application process for one switch operation.

On the other hand, in the conventional apparatus using the glow starter, even if the filaments 30 and 32 are not sufficiently preheated, if the contact of the glow starter is separated, a high voltage application process is executed. For this reason, in the conventional apparatus using the glow starter, the fluorescent lamp 14 does not shift to the lighting state by one high voltage application, and the high voltage is applied between the filaments 30 and 32 a plurality of times until the fluorescent lamp 14 is turned on. May be applied.

In order to prolong the life of the fluorescent lamp 14, it is desirable that the number of times of applying a high voltage to the filaments 30, 32 is small. Therefore, according to the fluorescent lamp lighting device of the present embodiment, the fluorescent lamp 14 can have a longer life than the conventional device using a glow starter.

In the fluorescent lamp lighting device of the present embodiment, the current flowing through the lighting series circuit 50 is cut off by utilizing the change in the resistance value of the positive temperature coefficient thermistor 46, and the back electromotive force is applied to the ballast 12 by one. It is to be generated once. According to such a method, it is possible to suppress the noise generated at the time of generation of the back electromotive force to one time, unlike the case where the blinking of the opening and the short circuit is repeatedly caused to occur repeatedly at the contact of the glow starter. Therefore, according to the fluorescent lamp lighting device of the present embodiment, for example, the influence on external devices such as a television and a radio disposed near the fluorescent lamp 14 can be reduced.

The fluorescent lamp lighting device of this embodiment is driven by the AC power supply as described above. For this reason, as shown in FIG. 2, the varistor 48 needs to exhibit a target characteristic with respect to a positive voltage and a negative voltage. Also,
In the fluorescent lamp lighting device of the present embodiment, in order to reliably light the fluorescent lamp 14, the varistor 48 needs to flow a sufficient current with respect to the application of the initial voltage V1. Therefore, the varistor 48 is required to have a steep rising operating voltage characteristic.

FIG. 4 shows characteristics of another varistor applicable to the fluorescent lamp lighting device of the present embodiment. The characteristic shown in FIG. 4 has a target characteristic with respect to a positive voltage and a negative voltage, and has an operating voltage characteristic showing a steep rise. That is, the characteristics of the varistor 48 used in the fluorescent lamp lighting device of the present embodiment need only satisfy the two requirements, and are not limited to those having the characteristics shown in FIG. 2. For example, as shown in FIG. Characteristics.

The varistor 48 is preferably a metal oxide varistor, but is not limited to this as long as desired characteristics can be obtained. A varistor mixed with a new material or a varistor made of a new material may be used.

The voltage of the AC power supply is generally 100
Although the voltage is set to V or 200 V, the voltage applied to the fluorescent lamp lighting device of the present embodiment is not limited to these, and may be applied to other voltages.

The above embodiments correspond to the fluorescent lamp lighting device according to the first aspect and the fluorescent lamp lighting device according to the second aspect.

Embodiment 2 Next, a second embodiment of the present invention will be described with reference to FIG. (1) Detailed Description of Configuration of Second Embodiment FIG. 5 shows a configuration diagram of a fluorescent lamp starter device 52 which is a main part of the present embodiment. The fluorescent lamp lighting device of the present embodiment is characterized in that the circuit configuration shown in FIG. 1 is realized using the fluorescent lamp starter device 52.

The fluorescent lamp starter device 52 includes a base 54.
And a glass case 56. Inside the package 58, a positive temperature coefficient thermistor 46 and a varistor 48 connected in series are housed. The package 58 has the same shape as a glow starter package used in a conventional fluorescent lamp lighting device.

(2) Detailed Operation and Operation of the Second Embodiment The positive temperature coefficient thermistor 46 and the varistor 48 are maintenance-free unlike the glow starter. Further, they are small and lightweight, and can be easily stored inside the fluorescent lamp lighting device. Therefore, when a fluorescent lamp lighting device is newly designed, all necessary circuits including the lighting series circuit 50 can be built in the device.

The fluorescent lamp lighting device shown in FIG. 1 is a conventional device using a glow starter, except that the circuit connected in parallel to the fluorescent lamp 14 is not a glow starter but a series circuit 50 for lighting. It has the same configuration as. Therefore, the fluorescent lamp lighting device shown in FIG. 1 can be easily realized only by replacing the glow starter provided in the conventional device with the lighting series circuit 50.

The fluorescent lamp starter device 52 shown in FIG.
Has a built-in lighting series circuit 50 therein and is compatible with a glow starter. For this reason,
According to the fluorescent lamp starter device 52, the glow starter included in the conventional device can be easily replaced with the lighting series circuit 50. Therefore, the fluorescent lamp lighting device of the present embodiment can be easily realized by using the conventional fluorescent lamp lighting device.

The above embodiment corresponds to the fluorescent lamp lighting device according to the third aspect and the fluorescent lamp starter device according to the fifth aspect.

Embodiment 3 Next, a third embodiment of the present invention will be described with reference to FIG. (1) Detailed Description of Configuration of Third Embodiment FIG. 6 is a conceptual diagram of a fluorescent lamp lighting device according to a third embodiment of the present invention. The fluorescent lamp lighting device of the present embodiment is realized by adding a noise prevention capacitor 60 connected in parallel with the lighting series circuit 50 to the circuit configuration shown in FIG.

(2) Detailed Description of Operation and Operation of Embodiment 3 Generally, a varistor has a capacitance of about 100 to 2000 pF. Therefore, in the fluorescent lamp lighting device of the present embodiment, the lighting series circuit 50 itself functions as a noise prevention circuit. For this reason, the fluorescent lamp lighting device of the present embodiment does not necessarily need to incorporate a noise prevention capacitor (see FIG. 7) used in a conventional device using a glow starter.

However, in the fluorescent lamp lighting device of the present embodiment, a high voltage is applied between the filaments 30 and 32 due to the back electromotive force generated by the ballast 12, and as a result, the fluorescent lamp 14 is turned on. During the transition, relatively large noise is generated. The above noise cannot be completely absorbed by the varistor 48.

The noise preventing capacitor 60 provided in the fluorescent lamp lighting device of this embodiment effectively absorbs the noise generated in the circuit as described above. For this reason, according to the fluorescent lamp lighting device of the present embodiment, noise generated when the fluorescent lamp 14 is started and turned on can be suppressed to a sufficiently small value.

Incidentally, in the above embodiment, the lighting series circuit 50 is limited to a structure in which the lighting series circuit 50 is built in the fluorescent lamp lighting device. However, the present invention is not limited to this. As in the case of Embodiment 2, the lighting series circuit 50 may be realized by the fluorescent lamp starter device 52 shown in FIG.

The above embodiment corresponds to the fluorescent lamp lighting device according to the fourth aspect.

Since the present invention is configured as described above, it has the following effects. Claim 1
According to the second aspect of the present invention, since the preheating of the fluorescent lamp and the application of a high voltage to the fluorescent lamp are controlled by the lighting series circuit including the positive temperature coefficient thermistor and the varistor, large noise is generated. Without
The fluorescent lamp can be reliably turned on in a short time without impairing the life of the fluorescent lamp.

According to the third aspect of the present invention, since the lighting series circuit is housed in a package compatible with the glow starter, the glow starter of the conventional fluorescent lamp lighting device is changed to a lighting series circuit. Thus, the fluorescent lamp lighting device of the present invention can be easily realized.

According to the fourth aspect of the present invention, since the noise prevention capacitor is connected to the lighting series circuit, the noise level can be further suppressed and the influence on external devices can be reduced.

According to the fifth aspect of the present invention, since the lighting series circuit is housed in a package compatible with the glow starter, the lighting series circuit can be easily replaced with the glow starter to easily use the conventional fluorescent lamp. It can be incorporated in a lighting device.
