Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a discharge lamp lighting device for starting and lighting a discharge lamp.

Conventional technology In recent years, discharge lamp lighting devices have become smaller and more stable.

In order to improve flicker, etc., a discharge lamp lighting device is used that lights a discharge lamp using a power source whose output voltage has a constant polarity. A conventional discharge lamp lighting device has a configuration as shown in FIG. 4, for example. A conventional discharge lamp lighting device will be described below.

In Fig. 4, 1 is a DC power supply, 2 is an AC power supply, 3 is a full-wave rectifier, 4 is a capacitor, 6 is a step-down chopper circuit,
6 is a capacitor, 7 is a diode, 8 is a discharge lamp, 9 is a starting circuit, 10 is a resistor, 11 is a step-up transformer with an intermediate tap, 12 is a one-way conduction reverse blocking 2 which is a voltage sensitive switch
A terminal thyristor (hereinafter referred to as thyristor), 13 is a capacitor. An AC power source 2 is connected to the input end of the full-wave rectifier 3, and a capacitor 4 is connected to the output end.

A step-down chopper circuit 5 is connected to the output end of the capacitor 4 so that the charge stored in the capacitor 6 flows through a diode 7 to a discharge lamp 8.

Further, in the starting circuit 9, the step-up transformer 11 with an intermediate tag and the thyristor 12 are connected in series, and further,
A diode 7 with positive polarity of the step-down chopper circuit 5 is connected in the forward direction, the other end of the diode 7 is connected to the step-up transformer 11, and one end of the capacitor 13 is connected to the intermediate tap of the step-up transformer 11. and capacitor 13
The other end is connected to the end of the thyristor 12 that is not connected to the step-up transformer 11, and the connection point between the capacitor 13 and the thyristor 12 is connected to the end where the polarity of the step-down chopper circuit becomes negative via a resistor 1o. There is.

In the above configuration, charges are accumulated in the capacitor 4 by the AC power supply 2 via the full-wave rectifier 3, and a smoothed DC voltage is obtained. The DC current flowing from the capacitor 4 is controlled intermittently by a transistor in the step-down chopper circuit 5 to limit the current, and the voltage of the capacitor 6 is set to a predetermined voltage. Furthermore, after the discharge lamp 8 is started and lit, it is maintained lit by the current flowing from the step-down chopper circuit 6 through the diode 7. Further, the operation of the starting circuit 9 will be explained. A current flows from the positive polarity end of the step-down chopper circuit 5 to the capacitor 13 via the diode 7, the resistor 1o, and a part of the step-up transformer 11, and accumulates charges. When the voltage across the capacitor 13 reaches the breakover voltage of the thyristor 12, the thyristor 12 becomes conductive and the capacitor 13° intermediate tap of the step-up transformer 11 - connection point between the step-up transformer 11 and the thyristor 12 - the thyristor 12
- current flows in the direction of the capacitor 13; Therefore, a high voltage pulse is generated at both ends of the step-up transformer 11 such that the end to which the thyristor 12 is not connected is positive.

Therefore, the starting circuit 9 output from the step-up transformer 11
The polarity of the output pulse is the same as that of the step-down chopper circuit 5. Therefore, the output pulse of the starting circuit 9 is blocked by the diode 7 and is not input to the step-down chopper circuit 6, but is applied to the discharge lamp 8 and starts the discharge lamp 8. After the discharge lamp 8 is started, the step-down chopper circuit 6 maintains the lighting.

Problems to be Solved by the Invention In such a conventional discharge lamp lighting device, all of the current flowing through the discharge lamp 8 flows through the diode 7 of the starting circuit 12. Unfortunately, the loss occurring in diode 7 is
The problem is that the current flowing through the discharge lamp 8 is multiplied by the forward voltage of the diode 7 (generally 1 to 2 V), resulting in a very large loss for the entire discharge lamp lighting device.

In addition, a large current flows through the diode 7, and it also needs to withstand the high voltage for starting.
This required a high-voltage element and was expensive. Furthermore, problems tend to occur in terms of lifespan and reliability.

Means for Solving the Problems The present invention solves these conventional problems by providing a power supply circuit having a constant output voltage polarity and a current limiting function, and a power supply circuit connected to the output end of the power supply circuit. A series circuit of at least a step-up transformer with an intermediate tap and a voltage sensitive switch, a capacitor whose one end is connected to the intermediate tap of the step-up transformer and the other end connected to the anti-transformer terminal of the switch, and a charging current of the capacitor. a starting circuit comprising a resistor connected to limit the discharge lamp; a discharge lamp connected to the output end of the starting circuit; and a discharge lamp connected between the output end of the power supply circuit and the discharge lamp, for lighting the discharge lamp. a normally-off type thermally responsive mechanical switch that is heated and closed when the thermally responsive mechanical switch is opened; The present invention is a discharge lamp lighting device configured to apply a starting high voltage by the pulse between the electrodes of the discharge lamp so as not to input the voltage.

Effect of the Invention With the above-described configuration, the present invention can completely short-circuit the portion of the starting circuit through which the current flowing through the discharge lamp (hereinafter referred to as lamp current) flows when the discharge lamp is lit, and at the same time, the high voltage for starting can be can be applied to the discharge lamp to start it.

Embodiment FIG. 1 is a circuit diagram of a discharge lamp lighting device in an embodiment of the present invention. In FIG. 1, 1 is a DC power supply consisting of an AC power supply 2, a full-wave rectifier 3, and a capacitor 4, 5 is a step-down chopper circuit that is a current limiting circuit, 6 is an output smoothing capacitor of the step-down chopper circuit 5, and 8 is a DC power supply. A discharge lamp 9 includes a diode 7, a resistor 10, a step-up transformer 11 with an intermediate tag, a thyristor 12 which is a voltage sensitive switch, and a capacitor 13.
14 is a bimetal normally-off type thermally responsive mechanical switch that is heated and closed when the discharge lamp 8 is turned on; 15 is a bimetallic starter circuit consisting of a DC power source 1 and a step-down chopper circuit 5; This is a power supply circuit that is constant and has a current limiting function.

An AC power supply 2 is connected to the input end of the full-wave rectifier 3, and a capacitor 4 is connected to this output end, which becomes the output end of the DC power supply 1. A step-down chopper circuit 5, which is a current limiting circuit, is connected to the output end of the DC power supply 1 to form a power supply circuit 15, a starting circuit 9 is connected to the output end, and a discharge lamp 8 is connected to the output end. The starting circuit 9 has a series circuit of a step-up transformer 11 with an intermediate tap and a thyristor 12 which is a voltage sensitive switch, and one end is connected to the intermediate tap of the step-up transformer 11 and the other end is connected to the anti-transformer terminal of the thyristor 12. A resistor 10 whose one end is connected to the anti-transformer side terminal of the capacitor 13 and the other end is connected to the negative voltage terminal of the output terminal of the power supply circuit 15 so as to limit the connected capacitor 13 and the charging current of the capacitor 13. In addition, the power supply circuit 16 is configured to prevent the pulse generated in the step-up transformer 11 of the starting circuit 9 from being input to the power supply circuit 15 and to apply the pulse, that is, the high voltage for starting, between the electrodes of the discharge lamp 8. A diode 7 is connected in the forward direction of the lamp current between the positive voltage terminal of the output terminal and the anode of the discharge lamp 8, and the terminal of the step-up transformer 11 to which the thyristor 12 is not connected is connected to the cathode of the diode 7. Connect it and use it as the positive output end,
The anti-thyristor side terminal of the resistor 10 is configured as a negative output terminal.

Further, the above configuration is similar to the conventional example shown in FIG. What is different from the conventional example is the bimetal 14, which is a normally-off type thermally responsive mechanical switch that is heated and closed when the discharge lamp 8 is turned on, and connects the positive voltage terminal of the output terminal of the power supply circuit 15 and the discharge lamp 8. A diode 7 is connected in parallel between the anode and the anode of the diode 7. The bimetal 14 is arranged near the discharge lamp 8, and receives the heat generated when the discharge lamp 8 is turned on to close the contacts of the bimetal 14.

The operation of the embodiment shown in FIG. 1 will be explained below.

A smoothed DC voltage is obtained from the AC power supply 2 to the capacitor 4 via the full-wave rectifier 3, and the DC current flowing from the capacitor 4 is controlled intermittently by the transistor in the step-down chopper circuit 6 to provide current-limiting control to the step-down chopper circuit 5. Setting the output voltage, ie, the output voltage of the power supply circuit 16, to a predetermined voltage is the same as in the conventional example shown in FIG. 4. In addition, in the starting circuit 9 before starting the discharge lamp 8, the capacitor 13 is charged via the diode 7, the step-up transformer 11, and the resistor 10, and when the thyristor 12 is turned on, a positive high voltage is applied to the diode 7 side terminal of the step-up transformer 11. The process of generating a pulse, applying it to the discharge lamp 8 to start the discharge lamp 8, and stopping the operation after starting is also the same as in the conventional example shown in FIG. 4. What is different from the conventional example is the starting circuit 9 and the bimetal 14 after lighting. Before starting the discharge lamp 8, the bimetal 14 is at room temperature and the contacts are open. However, at the time of starting, the starting circuit 9 performs the same operation as in the conventional example to start the discharge lamp 8. After the discharge lamp 8 is started, the temperature of the discharge lamp 8 rises, and therefore the temperature of the bimetal 14 also rises, and the contacts close. While the light is on, the contact of the bimetal 14 remains closed. When the contacts of the bimetal 14 are closed, the diode 7, which is the lamp current conducting part of the starting circuit, is short-circuited by the bimetal 14. Therefore, the lamp current flows through the bimetal 14 without passing through the diode 7. Furthermore, when the discharge lamp 8 goes out or is immediately turned on again, the starting circuit operates while the discharge lamp 8 is still hot. That is, with the bimetal 14 still closed,
The starting circuit 9 operates to generate a high voltage pulse. That is, the output voltage of the step-down chopper circuit 5 charges the capacitor 13 via the diode 7, the resistor 1o, and the step-up transformer 11, causing the thyristor 12 to break down, and then the charge in the capacitor 13 is transferred to the step-up transformer 1.
1 and the thyristor 12, and attempts to generate a high voltage pulse in the step-up transformer 11 according to the step-up ratio. However, due to the bimetal 14, the diode 7
is short-circuited, the current flowing from the capacitor 13 through a part of the step-up transformer 11 and the thyristor 12 generates magnetic flux in the core of the step-up transformer 11, and due to the change, the intermediate tap of the step-up transformer 11 and the anti-thyristor terminal are connected. When a voltage is generated in the windings between the two, a current flows through the bimetal 14 to the step-down chopper circuit 5 and the DC power supply 1. The current cancels the change in the magnetic flux of the core of the step-up transformer 11, and the voltage in the winding between the center tap of the step-up transformer 11 and the anti-thyristor side terminal decreases and disappears. Therefore, even if the starting circuit 9 operates while the bimetal 14 is closed, no high voltage is generated.

As described above, in this embodiment, the discharge lamp 8 can be started by applying a high voltage pulse higher than the power supply voltage as before, and the lamp current conduction path of the starting circuit 9 is connected to the bimetal 14 when the discharge lamp 8 is lit. With the simple and inexpensive configuration of short-circuiting, it is possible to eliminate the large loss that occurs in the diode, which is the part that blocks high voltage pulses from the power supply circuit 15 side, and reduces the loss in the discharge lamp lighting device. can be reduced. Furthermore, even when the discharge lamp 8 goes out or is immediately turned on again, high voltage can be prevented from being generated by the starting circuit 9, and problems can be avoided even when the discharge lamp 8 is still hot and the bimetal 14 is still closed. You can avoid it. When the temperature of the discharge lamp 8 and the bimetal 14 decrease and the contacts open, a high voltage pulse is immediately generated in the starting circuit 9 and can be applied to the discharge lamp 8. Therefore, the discharge lamp 8 can be restarted safely.

In addition, especially when the discharge lamp 8 is a high-pressure discharge lamp, in which the arc tube becomes high temperature and high pressure when turned on, the temperature and pressure do not immediately drop immediately after the lamp is turned off, and therefore the voltage required for starting is low. There are things that increase. In such a discharge lamp, when the discharge lamp goes out or when trying to immediately relight it, even if the high voltage generated by the starting circuit 9 is applied to the discharge lamp 8, the voltage required for starting is higher; There is a period in which the discharge lamp 8 cannot be started until the temperature and pressure of the discharge lamp 8 decrease and the voltage required for starting becomes lower than the high voltage generated by the starting circuit 9. At this time, if the bimetal 14 were not present, the high voltage generated in the starting circuit 9 would remain applied to the discharge lamp 8, the diode 7, and the step-up transformer 11 itself during this period, but by providing the bimetal 14, The starting circuit 9 continues until the temperature of the discharge lamp 8 decreases and the contacts of the bimetal 14 open.
It is possible to stop generating high voltage or lower the generated voltage. As a result, insulation deterioration of the discharge lamp 8, diode 7, step-up transformer 11, and other voltage sections can be reduced, resulting in safety, and cheaper parts can still be used.
Further, scattering of the electrode material due to high voltage in the electrodes of the discharge lamp 8 can be reduced, and the life of the discharge lamp 8 can be extended.

FIG. 2 shows a discharge lamp lighting device according to a second embodiment of the present invention. In FIG. 2, DC power supply 1. The discharge lamp 8 is the same as in the first embodiment. 2o is a current limiting circuit consisting of a resistor 21 connected to the positive output terminal of the DC power supply 1; 22 is a current limiting circuit consisting of diodes 7 and 27, a resistor 23, a step-up transformer 24 with an intermediate tap, a thyristor 26 as a voltage sensitive switch, and a capacitor 26; 28 is a bimetal normally-off type thermally responsive mechanical switch that is heated and closed when the discharge lamp 8 is turned on; 29 is a bimetallic switch that is a thermally responsive mechanical switch of the normal-off type that is heated and closed when the discharge lamp 8 is turned on; This is a power supply circuit with a current limiting function. A current limiting circuit 20 is connected to the output end of the DC power supply 1 to form a power supply circuit 29, a starting circuit 22 is connected to the output end, and a discharge lamp 8 is connected to the output end.

The starting circuit 22 is a series circuit of a step-up transformer 24 with an intermediate tap and a thyristor 25 which is a voltage sensitive switch, and one end is connected to the intermediate tap of the step-up transformer 24 and the other end is connected to the anti-transformer side terminal of the thyristor 25. A resistor 23 has one end connected to the intermediate tap of the step-up transformer 24 and the other end connected to the positive output end of the DC power supply 1 so as to limit the charging current of the capacitor 26, and a resistor 23 connected to the power supply circuit 29. At the positive output terminal of the power supply circuit 29, the pulses generated in the step-up transformer 24 of the starting circuit 22 are not input, and the DC high voltage accumulated in the pulses, that is, the starting high voltage is applied between the electrodes of the discharge lamp 8. A diode 7 is connected in the forward direction of the lamp current between the other end of a resistor 21 and the anode of the discharge lamp 8, and a diode 27 is connected to the terminal of the step-up transformer 24 that is not connected to the thyristor 25.
The anode of the diode 27 is connected to the cathode of the diode 27 to form a positive output terminal, and the anti-transformer side terminal of the thyristor 25 is connected to the negative output terminal of the current limiting circuit 20, that is, the negative output terminal of the power supply circuit 29. The negative output terminal of the starting circuit 22 is configured to be the negative output terminal of the starting circuit 22. Also, bimetal 2
The connections and operations of 8 are the same as in the first embodiment.

The operation of the second embodiment shown in FIG. 2 will be described below. A current flows from the positive output terminal of the DC power supply 1 to the starting circuit 22 via the resistor 21 of the current limiting circuit 20. Before starting the discharge lamp 8, the bimetal 14 is at room temperature and the contacts are open. At this time, in the starting circuit 22, the DC power supply 1
The capacitor 26 is charged via the resistor 23 from the positive output terminal of the step-up transformer 2 by turning on the thyristor 25.
A positive high voltage pulse is generated at the diode 27 side terminal of No. 4 and applied to the discharge lamp 8 via the diode 27.
starts and stops operation after starting.

Here, diode 7 blocks the high voltage pulse and also
When the discharge lamp 8 does not start with the first high voltage pulse, the diode 27 accumulates charge in the diode 7, the diode 27, the anode of the discharge lamp 8, etc., and increases the time during which high voltage is applied to the discharge lamp 8. That is, a high DC voltage is applied to make it easier to start the discharge lamp 8. After starting the discharge lamp 8,
The temperature of the discharge lamp 8 increases, and therefore the temperature of the bimetal 28 also increases and the contacts close. During lighting, the contacts of the bimetal 28 remain closed. When the contact of the bimetal 28 is closed, the diode 7, which is the lamp current conducting part of the starting circuit 22, is short-circuited by the bimetal 28, as in the first embodiment. Therefore, the lamp current flows through the bimetal 28 without passing through the diode door. In addition, discharge lamp 8
Similarly to the first embodiment, when the bimetal 28 is closed, the starting circuit 2
2 tries to operate, but no high voltage is generated.

As described above, in this embodiment, a high DC voltage can be applied to the discharge lamp 8, and it can be started more quickly. A simple and inexpensive configuration in which the current conduction path is short-circuited by the bimetal 28 can reduce losses in the discharge lamp lighting device. No voltage is generated, insulation deterioration of the discharge lamp 8, diodes 7, 27, step-up transformer 24, and other high voltage parts can be reduced, and the life of the discharge lamp 8 can be extended.

FIG. 3 shows a discharge lamp lighting device according to a third embodiment of the present invention. In Figure 3, 30 is a DC power supply, 31 is a DC power supply 3
This is a current limiting circuit consisting of a resistor 32 connected to the positive output terminal of 0, and its configuration and operation are the same as in the second embodiment. 8 is a discharge lamp, 33 is a starting circuit consisting of a resistor 34, a step-up transformer 36 with an intermediate tap, a thyristor 36 which is a voltage sensitive switch, and a capacitor 37, and 38 is a normally-off type thermal response which is heated and closed by the resistor 32. A bimetal switch 39, which is a mechanical switch, is a power supply circuit consisting of a DC power supply 30 and a current limiting circuit 31, which has a constant output voltage polarity and has a current limiting function.

A starting circuit 33 is connected to the output end of the current limiting circuit 31, and a discharge lamp 8 is connected to the output end. The starting circuit 33 includes a series circuit of a step-up transformer 35 with an intermediate tap, one end of which is connected to the anti-DC power supply end of the resistor 32, that is, the positive output end of the power supply circuit 39, and a thyristor 36, which is a voltage sensitive switch. A capacitor 37 has one end connected to the intermediate tap of the step-up transformer 36 and the other end connected to the anti-transformer terminal of the thyristor 36. One end is connected to the anti-transformer terminal of the thyristor 36 so as to limit the charging current of the capacitor 37. The terminal is connected to the negative output terminal of the power supply circuit 39, which is the negative output terminal of the DC power source 30, to serve as the negative output terminal of the starting circuit 33, and the anti-thyristor side terminal of the step-up transformer 35 is set as the positive output terminal. The bimetal 28 is placed near the resistor 32, and receives heat generated in response to the current flowing through the resistor 32 when the discharge lamp 8 is turned on, thereby closing the contact of the bimetal 28.

Connections and operations are similar to the first embodiment.

The operation of the third embodiment shown in FIG. 3 will be described below. A current flows from the positive output end of the DC power supply 30 to the starting circuit 33 via the resistor 32 of the current control circuit 31. Before starting the discharge lamp 8, the bimetal 38 is at room temperature and the contacts are open. At this time, in the starting circuit 33, the capacitor 37 is charged from the positive output terminal of the DC power supply 30 via the resistor 34, and when the thyristor 36 is turned on, a positive high voltage pulse is generated at the anti-thyristor side terminal of the step-up transformer 36, and discharged. The voltage is applied to the electric lamp 8 to start the discharge lamp 8, and after starting, the operation is stopped. After starting the discharge lamp 8, lamp current flows through the resistor 32. Therefore, the resistor 32 generates heat and its temperature rises, and therefore the temperature of the metal 38 also rises and the contact closes. During lighting, the contacts of the bimetal 38 remain closed. When the contacts of the bimetal 38 close, the step-up transformer 36, which is the lamp current conducting part of the starting circuit 33, is short-circuited by the bimetal 38, as in the first embodiment.

Therefore, the lamp current flows through the bimetal 3B without passing through the step-up transformer 35. Further, when the discharge lamp 8 goes out or is immediately turned on again, the starting circuit 33 tries to operate while the bimetal 38 is closed, but no high voltage is generated, as in the first embodiment.

As described above, in this embodiment, the discharge lamp 8 can be started by applying a high voltage pulse as in the first embodiment, and the lamp current conduction path of the starting circuit 33 is connected to the bimetal 38 when the discharge lamp 8 is lit. The loss of the discharge lamp lighting device can be reduced with a simple and inexpensive configuration in which the discharge lamp 8 is short-circuited, and the high voltage pulse is generated by the starting circuit 33 even when the discharge lamp 8 goes out or is immediately re-lit. Therefore, insulation deterioration of the discharge lamp 8, step-up transformer 3S, and other high voltage parts can be reduced, and the life of the discharge lamp 8 can be extended. Further, the bimetal 38 is operated by heat generated by the resistor 32 of the current limiting circuit 31. in general,
Since the discharge lamp 8 is difficult to cool due to its characteristics, it is difficult to set the operating temperature of the bimetal 38, and the restart time may be longer than necessary. On the other hand, the resistor 32 can be constructed to be easily cooled. Therefore, the operation of the bimetal 38 can be easily and reliably set to the required characteristics.

In the first, second and third embodiments described above, the DC power supplies 1 and 30 and the current limiting circuits 5 and 20°31 may have other configurations, respectively, and the power supply circuits 15 and 29
．． 39 may have another configuration, such as a rectified inverter output, as long as a limited current/voltage with constant polarity can be obtained at the starting circuit input terminal. Further, the bimetal 14, 28, 38 may be a normally-off type thermally responsive mechanical switch, such as a thermal switch. In addition, the bimetal 14, 28.38 is the discharge lamp 8
．． Although the operation is performed according to the heat of the resistors 21 and 32, it goes without saying that the operation may be performed using the heat of other things as long as the temperature changes according to the operation of the discharge lamp 8. Also,
The starting circuit 9, 22.33 is a series circuit of at least a step-up transformer with a center tap and a voltage sensitive switch, and one end is connected to the center tap of the step-up transformer and the other end is connected to the terminal on the opposite side of the switch. a capacitor connected to the capacitor and a resistor connected to limit the charging current of the capacitor; Any other type may be used as long as it is configured to apply the high voltage for starting using the pulse. Still, in the second embodiment, the resistor 23
is connected to the positive output terminal of DC power supply 1, but current limiting circuit 2
It may be connected to a voltage section other than the high voltage section, such as the output terminal of 0.

Effects of the Invention As described above, the discharge lamp lighting device of the present invention starts the discharge lamp by applying a high voltage to the discharge lamp, and also reduces loss in the starting circuit during lighting of the discharge lamp with an inexpensive and simple configuration. furthermore, immediate restart of the discharge lamp can be made safe.
