Description

  The present invention relates to a lighting device for a high pressure discharge lamp and a lighting device for lighting a high pressure discharge lamp.

  In general, a high-pressure discharge lamp has a characteristic that a discharge starts from a glow discharge to an arc discharge. Therefore, it is necessary to apply a high voltage pulse voltage in order to start glow discharge, and it is necessary to apply a voltage lower than the voltage to start glow discharge for a transition from glow discharge to arc discharge over a predetermined time. is there. In general, an igniter circuit is used to start glow discharge. Therefore, in order to properly light the high pressure discharge lamp, it is necessary to determine whether or not the igniter circuit is suitable for the lighting circuit.

Here, as a means for discriminating a discharge lamp for preventing erroneous mounting of discharge lamps having different ratings, there is a technique for detecting a lamp power of a discharge lamp by detecting an electrical characteristic during lighting (for example, a patent) Reference 1).
Japanese Patent Laid-Open No. 7-106088

However, in Patent Document 1, since the discharge lamp cannot be determined unless the discharge lamp is turned on, for example, the high pressure discharge lamp lighting device is initially turned on with low power for detection. There is a problem that the rise of the luminous flux becomes slow.

  Further, when a detection element for detecting electrical characteristics is provided between the discharge lamp terminals, the detection element is required to have a performance capable of withstanding a high voltage pulse voltage at the time of starting.

  In recent years, there is a demand for restarting a high-pressure discharge lamp and development of a mercury-free high-pressure lamp having a relatively high starting voltage. For these, for example, a high-pressure pulse voltage of 20 kV or more needs to be applied to the high-pressure lamp. Thus, when the starting voltage becomes high, it becomes difficult to find a detection element that can withstand this. In addition, when a high voltage pulse voltage is required, there is also a problem that the high voltage pulse voltage is attenuated by the wiring length between the high voltage discharge lamp and the igniter circuit.

  An object of the present invention is to provide a lighting device and a lighting device for a high-pressure discharge lamp that can determine whether or not they are suitable without operating an igniter circuit that generates a high-voltage pulse voltage when starting the high-pressure discharge lamp.

  A lighting device for a high-pressure discharge lamp according to the invention of claim 1 is a lighting circuit that supplies power for lighting the high-pressure discharge lamp to the high-pressure discharge lamp; an input terminal is connected to an output terminal of the lighting circuit; An igniter circuit that generates a high-voltage pulse voltage when starting the high-pressure discharge lamp; a detection element that is connected in parallel between the input terminals of the igniter circuit and detects an electrical characteristic of the igniter circuit; and detected by the detection element And a discriminating circuit for discriminating suitability between the igniter circuit and the lighting circuit based on the detected signal.

  In the present invention and the following inventions, definitions and technical meanings of terms are as follows unless otherwise specified. The high-pressure discharge lamp is a mercury lamp, a metal halide lamp, a high-pressure sodium lamp, or the like, and also includes a ceramic discharge lamp using an alumina tube as an arc tube.

  The lighting circuit converts direct current from a direct current power source into alternating current power and outputs the alternating current power. The igniter circuit is a circuit that generates a high voltage pulse voltage when starting the high pressure discharge lamp. For example, the igniter circuit generates a voltage of several kV to several tens of kV to cause glow discharge in the high pressure discharge lamp. The electrical characteristics of the igniter circuit are, for example, electrical characteristics indicating how much current value can be supplied to the high-pressure discharge lamp when the high-pressure discharge lamp is lit.

  The compatibility between the igniter circuit and the lighting circuit is, for example, the current value that can be supplied to the high pressure discharge lamp by the igniter circuit when the high pressure discharge lamp is lit at the rated power, and the current that the lighting circuit can supply to the high pressure discharge lamp. It means that the value matches. The detection element is an element that detects a divided voltage based on a current that flows when a DC voltage from the lighting circuit is applied as an electrical characteristic, and is, for example, a resistor or a capacitor.

  Further, it is preferable to select a resistance value as the detection element. This is because the detection element is an element that detects, as an electrical characteristic, a divided voltage based on a current that flows when a DC voltage from the lighting circuit is applied. This is because it is more suitable.

  According to a second aspect of the present invention, there is provided a lighting device for a high pressure discharge lamp according to the first aspect of the invention, wherein the lighting circuit applies a detection output voltage lower than the operable voltage of the igniter circuit to the detection element at the time of start-up. The discriminating circuit discriminates suitability between the igniter circuit and the lighting circuit based on a detection signal detected by the detecting element in a state where a detection output voltage is applied.

  The detection output voltage less than the operable voltage of the igniter circuit refers to a voltage in a range where the igniter circuit does not generate a high voltage pulse voltage. The detection signal detected by the detection element is a divided voltage based on a current that flows when a voltage from the lighting circuit is applied.

  According to a third aspect of the present invention, there is provided a lighting device for a high pressure discharge lamp according to the second aspect of the present invention, wherein the lighting circuit supplies output power to the high pressure discharge lamp according to a detection signal detected by the detection element. Is optimally adjusted.

  “Adjusting the output power supplied to the high-pressure discharge lamp optimally” means that the lighting circuit and the igniter circuit have power for lighting the high-pressure discharge lamp according to the detection result within the range of current values that can be supplied to the high-pressure discharge lamp. Is controlled and supplied.

  According to a fourth aspect of the present invention, there is provided the lighting device for a high-pressure discharge lamp according to any one of the first to third aspects, wherein the lighting device detects the change in state when the high-pressure discharge lamp is attached to or detached from a socket. A switching element connected in series with the operating element, wherein the discriminating circuit detects from the detecting element caused by the switching element operating in accordance with a state in which the lamp is mounted in the socket. The lamp mounting state is detected based on the value, and the suitability is determined when the mounting state is detected.

  The present invention prioritizes the detection of the mounting state of the high-pressure discharge lamp over the operation of the discrimination circuit, and by configuring in this way, at least the igniter circuit is operated when the high-pressure discharge lamp is not mounted. There is no. Since the detection element can also be used to detect the mounting of the high-pressure discharge lamp, the mounting detection function of the high-pressure discharge lamp can be added without adding a new member. Further, since the switch element is connected to the detection element connected in parallel between the input terminals of the igniter circuit, no special wiring for detecting the mounting of the high pressure discharge lamp is used.

  A lighting device according to a fifth aspect of the present invention is a high-pressure discharge lamp including the igniter circuit and the detection element of the lighting device for a high-pressure discharge lamp according to any one of the first to fourth aspects; A socket connected to the base of the lamp; and a lighting circuit and a discrimination circuit of the lighting device for a high-pressure discharge lamp according to any one of claims 1 to 5 electrically connected to the socket. And

  The present invention provides an illuminating device in which an igniter circuit is built in a base and a high voltage pulse voltage generated by the igniter circuit may not be applied between the igniter circuit and the base.

  A lighting device according to a sixth aspect of the present invention incorporates an igniter circuit and a detection element of the lighting device for a high pressure discharge lamp according to any one of the first to third aspects, and further includes a switch element according to the fourth aspect. And a lighting circuit for the lighting device for a high-pressure discharge lamp according to any one of claims 1 to 3 and a discrimination circuit according to claim 4 which are electrically connected to the socket. It is characterized by.

  The present invention can detect the mounting of the high-pressure discharge lamp without providing a special wiring in the wiring connecting the socket and the lighting circuit, and is suitable in a state where the high-pressure discharge lamp is not mounted. Even an igniter circuit does not operate.

  According to the first aspect of the present invention, it is possible to prevent the igniter circuit and the high-pressure discharge lamp from being damaged due to misuse of the lighting circuit.

  According to the invention of claim 2, since the detection output voltage less than the operable voltage of the igniter circuit is applied, generation of an unnecessary high voltage pulse voltage can be prevented, and the igniter circuit can be performed without lighting the high voltage discharge lamp. Can be determined.

  According to the invention of claim 3, since the lighting circuit and the igniter circuit supply lighting power within a range of an appropriate current value to the high pressure discharge lamp according to the detection result, the high pressure discharge lamp having a plurality of rated powers is supplied. Can respond.

  According to the invention of claim 4, since the operation of the igniter circuit is enabled only when the high-pressure discharge lamp is mounted on the socket, safety when the lamp is mounted can be ensured.

According to the invention of claim 5, since the high voltage pulse voltage generated by the igniter circuit need not be applied between the igniter circuit and the base, the high pressure discharge lamp can be started or restarted while using the conventional base. Can start.
According to the invention of claim 6, it is possible to detect the mounting of the high pressure discharge lamp without providing a special wiring in the wiring connecting the socket and the lighting circuit, and the high pressure discharge lamp is mounted. If it is not, even a suitable igniter circuit will not operate.

  FIG. 1 is a configuration diagram of a lighting device for a high-pressure discharge lamp according to a first embodiment of the present invention. Electric power is supplied from a commercial power supply 12 to the lighting circuit 11 of the lighting device. The AC power of the commercial power supply 12 is converted into DC power by the DC power supply unit 13 of the lighting circuit 11 and input to the inverter circuit 14. The inverter circuit 14 converts DC power into AC power supplied to the high-pressure discharge lamp 15, and AC power is supplied to the high-pressure discharge lamp 15 via the igniter circuit 16.

  The igniter circuit 16 is a circuit that generates a high voltage pulse voltage when the high pressure discharge lamp 15 is started. For example, the igniter circuit 16 generates a voltage of several kV to several tens of kV to cause the high pressure discharge lamp 15 to glow. In other words, the igniter circuit 16 rectifies the input voltage from the inverter circuit 14 of the lighting circuit 11 by the rectifier circuit 18, and when the obtained DC voltage exceeds the ON voltage of the switch element (gap) 19, the primary of the transformer 20. It is applied to the winding and outputs a high voltage pulse voltage to the secondary winding of the transformer 20. Further, between the input terminals of the igniter circuit 16, a resistor as a detection element 17 that detects the electrical characteristics of the igniter circuit 16 is connected in parallel.

  The inverter circuit 14 includes, for example, four switching elements Q1 to Q4 such as FETs, and the four switching elements Q1 to Q4 are switching-controlled by the control unit 21. Further, the lighting circuit 11 is provided with a determination circuit 22 that determines the suitability between the igniter circuit 16 and the lighting circuit 11 based on a detection signal detected by the detection element 17 of the igniter circuit 16.

  Next, an operation for determining compatibility between the igniter circuit 16 and the lighting circuit 11 when the high-pressure discharge lamp 15 is started will be described. When the commercial power supply 12 is turned on and the lighting circuit 11 is activated, compatibility between the igniter circuit 16 and the lighting circuit 11 is determined prior to the lighting operation of the high-pressure discharge lamp 15.

  First, the switching element Q1 of the inverter circuit 14 of the lighting circuit 11 is turned on, and the other switching elements Q2, Q3, Q4 are turned off. At this time, the control unit 21 controls the output voltage of the DC power supply unit 13 so that the output voltage of the lighting circuit 11 is less than the operable voltage of the igniter circuit 16. That is, in the igniter circuit 16, since the high voltage pulse voltage is output when the DC voltage of the rectifier circuit 18 exceeds the ON voltage of the switch element (gap) 19, the voltage is lower than the voltage at which the switch element 19 is turned ON. The control unit 21 controls the output voltage of the DC power supply unit 13. Note that, after the high-pressure discharge lamp 15 is once lit, the switch element 19 is generally selected to have a value that does not turn on at the voltage when the high-pressure discharge lamp 15 is lit.

  In a state where a voltage lower than the voltage at which the switch element 19 of the igniter circuit 16 is turned on is applied, the determination circuit 22 of the lighting circuit 11 generates at one end of the output of the lighting circuit 11 (a part different from the switching element Q1). Detect voltage value. That is, since the output voltage of the DC power supply unit 13 is applied to the series circuit of the switching element Q1-detecting element 17-discriminating circuit 22, the detecting element 17 is measured by measuring the divided voltage of the series circuit by the discriminating circuit 22. It is possible to determine the value of the divided voltage.

  The determination circuit 22 determines whether or not the suitability between the igniter circuit 16 and the lighting circuit 11 is satisfied depending on whether or not the divided voltage value of the detection element 17 satisfies a predetermined value. For example, it is determined whether or not the current value that can be supplied to the high-pressure discharge lamp 15 by the igniter circuit 16 matches the current value that can be supplied to the high-pressure discharge lamp 15 by the lighting circuit 11. The voltage value of the detection element 17 corresponding to the current value is preset in the determination circuit 22 as a predetermined value.

  FIG. 2 is an explanatory diagram of discrimination criteria in the discrimination circuit 22. Now, it is assumed that the lighting circuit 11 is capable of supplying lighting power to both a 100 W high pressure discharge lamp and a 70 W high pressure discharge lamp. For example, when the voltage value of the detection element 17 is in the range of 1 V to 1.5 V, it is determined that the detection element 17 is an igniter circuit 16 for lighting the high-pressure discharge lamp 15 of 100 W, and the voltage of the detection element 17 is determined. When the value is in the range of 1.5V to 2V, it is determined that the igniter circuit 16 for lighting the 70 W high-pressure discharge lamp 15 is used.

  In this case, when the voltage value of the detection element 17 exceeds 2V or less than 1V, the lighting circuit 11 determines that the non-conforming igniter circuit 16 is connected. On the other hand, when the voltage value of the detection element 17 is in the range of 1V to 1.5V and in the range of 1.5V to 2V, it is determined that the suitable igniter circuit 16 is connected.

  The determination result of the compatibility between the igniter circuit 16 and the lighting circuit 11 determined by the determination circuit 22 is input to the control unit 21. When the detection value detected by the detection element 17 is an appropriate value, the lighting is performed. The control unit 21 of the circuit 11 shifts to an operation for starting the high-pressure discharge lamp 15. That is, when the voltage value of the detection element 17 is in the range of 1V to 1.5V, the operation starts to start the 100 W high-pressure discharge lamp 15, and the voltage value of the detection element 17 is 1.5V to 2V. Is within the range, the operation starts so as to start the 70 W high-pressure discharge lamp 15. As described above, the lighting circuit 11 optimally adjusts the output power supplied to the high-pressure discharge lamp 15 in accordance with the detection signal detected by the detection element 17. Therefore, it can respond to a plurality of high pressure discharge lamps having different rated powers.

  FIG. 3 is an output waveform diagram of the lighting circuit 11 and the determination circuit 22 from the start of the lighting circuit 11 to the lighting of the high-pressure discharge lamp 15. The upper side of FIG. 3 shows the detection voltage of the discrimination circuit 22, and the lower side of FIG. 3 shows the waveform of the output of the lighting circuit 11 (input of the igniter circuit 16). At time t0, the lighting circuit 11 is connected to the commercial power supply 12, and the output voltage of the lighting circuit 11 starts to be a voltage that is less than the operable voltage of the igniter circuit 16. From time 1 to time t2, a voltage lower than the operable voltage of the igniter circuit 16 is continuously output. This period is a period for determining compatibility between the igniter circuit 16 and the lighting circuit 11. If the detection value detected by the detection element 17 is an appropriate value, the control unit 21 proceeds to an operation of starting the high-pressure discharge lamp 15 at time t2.

  When starting the high pressure discharge lamp 15, the lighting circuit 11 outputs an operable voltage of the igniter circuit 16. As a result, the igniter circuit 16 operates and a high voltage pulse voltage is applied to the high pressure discharge lamp to generate glow discharge. A voltage lower than the voltage for starting glow discharge is continuously applied from time t2 to time t3 for the transition from glow discharge to arc discharge, and the high-pressure discharge lamp 15 is turned on at time t3.

  Thus, when starting the high-pressure discharge lamp 15, the output voltage of the DC power supply unit 13 is increased to a voltage at which the igniter circuit 16 can operate and higher than the voltage at which the high-pressure discharge lamp 15 can undergo arc transition, thereby switching elements Q1 to Q4. The switching operation is performed. In order to turn on the high-pressure discharge lamp 15, both a relatively high voltage for generating glow discharge and a relatively low voltage for shifting from glow discharge to arc discharge are required. About 500V is common.

  The switching method of the switching elements Q1 to Q4 is that the switching elements Q2 and Q3 are turned off, the switching element Q1 is turned on and off at a high frequency, the switching element Q4 is turned on, the switching elements Q1 and Q4 are turned off, and the switching element Q2 is turned on and off at a high frequency. The period during which the switching element Q3 is turned on is alternately repeated in the lighting cycle of the high-pressure discharge lamp 15. The power control after the high-pressure discharge lamp 15 is turned on is performed by the on-duty of the switching elements Q1 and Q2 that are turned on and off at a high frequency.

  In this way, the lighting circuit 11 can output the output voltage up to a voltage at which the igniter circuit 16 can operate and a voltage at which the high-pressure discharge lamp 15 can undergo arc transition only when the detection value of the detection element 17 is within a predetermined range. The high pressure discharge lamp 15 is turned on by controlling so as to be raised.

In the above description, the detection element 17 of the igniter circuit 16 has been described as a resistor. However, a divided voltage based on a current flowing when a DC voltage from the lighting circuit 11 is applied is detected as an electrical characteristic. As long as it is an element that can be used, a capacitor may be used instead of a resistor. In the case of a capacitor, the divided voltage is detected in a transient range from when a DC voltage is applied until the capacitor is charged. Therefore, the detection element 17 is preferably a resistor.
FIG. 4 is a configuration diagram of an illuminating device in which the igniter circuit 16 is built in the base 23 of the high-pressure discharge lamp 15 and the high-pressure discharge lamp 15 and the igniter circuit 16 are integrated. An igniter circuit 16 is built in the base 23 of the high-pressure discharge lamp 15, and a socket 24 connected to the base 23 of the high-pressure discharge lamp 15 is connected to the connecting portion between the lighting circuit 11 and the igniter circuit 16 according to the embodiment of the present invention. Is provided.

  Thereby, since the igniter circuit 16 is built in the base 23 of the high-pressure discharge lamp 15, the wiring length between them is shortened. Further, since the high voltage pulse voltage generated by the igniter circuit 16 does not have to be applied between the igniter circuit 16 and the base 23, the high voltage pulse voltage can be increased without being restricted by the upper limit voltage that can be applied to the base 23. Application to the discharge lamp 15 is possible. Therefore, the high pressure discharge lamp can be started or restarted while using the conventional base.

  Next, a second embodiment will be described. Compared with the first embodiment, the present embodiment has a configuration in which the switch element is connected in series with the detection element 17 and the socket 24, and the igniter circuit 16 is not 23, but of the lighting device. Although it differs in providing in socket 24, since others are the same structures, while omitting illustration, the explanation about the same numerals is omitted. The switch element is provided so as to be closed when the high pressure discharge lamp 15 is attached to the socket 24 and to be opened when the high pressure discharge lamp 15 is removed from the socket 24.

  In the present embodiment, the determination circuit 22 detects the mounting of the high pressure discharge lamp. That is, in addition to the first embodiment, the determination circuit 22 can determine whether or not the lamp is mounted based on the value of the detection circuit 17 of the igniter circuit 16. More specifically, when the commercial power supply 12 is turned on and the lighting circuit 11 is activated, the switching element Q1 of the inverter circuit 14 of the lighting circuit 11 is turned on and the other switching elements Q2, Q3, and Q4 are turned off. . At this time, the control unit 21 controls the output voltage of the DC power supply unit 13 so that the output voltage of the lighting circuit 11 is less than the operable voltage of the igniter circuit 16. In this state, the discrimination circuit 22 of the lighting circuit 11 detects whether or not a voltage value is generated at one end of the output of the lighting circuit 11 (a portion different from the switching element Q1) prior to the discrimination of the igniter circuit 16.

  That is, when the high-pressure discharge lamp 15 is mounted in the socket 24, the switch element is closed, so that the output voltage of the DC power supply unit 13 is a series circuit of the switching element Q1-detection element 17-switch element-discriminating circuit 22. Therefore, it is possible to determine whether or not a voltage is generated in the detection element 17 by measuring the divided voltage of the series circuit by the determination circuit 22. Then, the determination circuit 22 determines whether or not the lamp is mounted based on whether or not the divided voltage value of the detection element 17 has reached a threshold value indicating a state in which the high-pressure discharge lamp 15 is mounted. As a result, when the determination circuit 22 determines that the high-pressure discharge lamp 15 is mounted on the socket 24, the determination of the igniter circuit 16 is performed in the same manner as in the first embodiment.

  According to the present embodiment, in addition to the operation of the first embodiment, even if the igniter circuit 16 that fits temporarily does not operate unless the high pressure discharge lamp 15 is mounted, the socket does not operate. Even if the igniter circuit 16 is provided integrally with the igniter 24, the igniter circuit 16 is not operated when the high-pressure discharge lamp 15 is mounted. Further, since the detection element 17 is also used to detect the mounting of the high-pressure discharge lamp 15, the mounting detection function of the high-pressure discharge lamp 15 can be added without adding a new member. Further, since the switch element (not shown) is connected to the detection element 17 connected in parallel between the input terminals of the igniter circuit 16, the lighting circuit 11 and the socket 24 are detected in order to detect the mounting of the high-pressure discharge lamp 15. There is no need to use special wiring to connect the two.
