Description

本発明の実施形態は、発光素子を有する光源が着脱可能な点灯装置、および光源と点灯装置を用いた照明装置に関する。 An embodiment of the present invention relates to a lighting device having a light source having a light emitting element and having a detachable light source, and a lighting device using the light source and the lighting device.

従来、器具側に点灯回路を有する点灯装置が設置され、この点灯装置に対して発光素子を有する光源が着脱可能に装着される照明装置がある。 Conventionally, there is a lighting device in which a lighting device having a lighting circuit is installed on the fixture side, and a light source having a light emitting element is detachably attached to the lighting device.

このような光源が着脱式の照明装置では、光源が点灯装置に装着されていない状態で、点灯回路が動作することは好ましくないため、点灯装置によって光源の装着有無を検出し、装着有の場合に点灯回路を動作させるようにしている。この場合、光源側に検出抵抗を配置し、光源の装着有無に応じて変化する電圧値によって光源の装着有無を検出している。 In such a lighting device with a detachable light source, it is not preferable that the lighting circuit operates when the light source is not mounted on the lighting device. Therefore, the lighting device detects whether or not the light source is mounted, and if the light source is mounted. The lighting circuit is operated. In this case, a detection resistor is arranged on the light source side, and the presence / absence of the light source is detected by the voltage value that changes depending on the presence / absence of the light source.

しかし、光源の装着有無を検出するには光源側に検出抵抗を配置することが必要であり、光源側に検出抵抗を配置できない場合や、光源の簡素化等のために光源側に検出抵抗を配置しない場合には、光源の装着有無を検出することができない。 However, in order to detect whether or not the light source is attached, it is necessary to place a detection resistor on the light source side, and if the detection resistor cannot be placed on the light source side, or if the light source is simplified, the detection resistor is placed on the light source side. If it is not arranged, it is not possible to detect whether or not the light source is attached.

The lighting circuit supplies lighting power to a light source having a light emitting element. The terminal portion has a first terminal, a second terminal, and a third terminal to which the light source is detachably connected. The output side of the lighting circuit is connected to the 1st terminal and the 3rd terminal, and the space between the 1st terminal and the 2nd terminal is open. When the light source is attached, the space between the 1st terminal and the 2nd terminal is open. It is connected on the light source side, and a light emitting element is connected between the second terminal and the third terminal. The mounting detection resistor is connected between the second terminal and the third terminal. The mounting detection unit is connected to the first terminal side and the mounting detection resistor to detect the voltage, and detects whether or not the light source is mounted by the voltage value that changes depending on whether or not the light source is mounted. The control unit controls the lighting circuit by detecting whether or not the light source is mounted by the mounting detection unit. At the time of mounting detection by the mounting detection unit, a voltage less than a predetermined value at which a predetermined light emitting element does not light is supplied to the output side of the lighting circuit.

本発明によれば、光源が検出抵抗を備えなくても、光源の装着有無を検出することが期待できる。 According to the present invention, even if the light source does not have a detection resistor, it can be expected to detect whether or not the light source is attached.

一実施形態を示す点灯装置の回路図である。It is a circuit diagram of the lighting device which shows one Embodiment.

以下、一実施形態を、図１を参照して説明する。 Hereinafter, one embodiment will be described with reference to FIG.

照明装置10は、光源11、およびこの光源11を点灯させる点灯装置12を備えている。 The lighting device 10 includes a light source 11 and a lighting device 12 for lighting the light source 11.

そして、光源11は、筐体15、この筐体15に配設された光源側端子部16および発光素子17を備えている。 The light source 11 includes a housing 15, a light source side terminal portion 16 arranged in the housing 15, and a light emitting element 17.

光源側端子部16は、第１端子16a、第２端子16bおよび第３端子16cを備えている。これら端子16a，16b，16cは、筐体15の外部に臨ませて所定の位置に配設されている。第１端子16aと第２端子16bとは電気的に接続されている。 The light source side terminal portion 16 includes a first terminal 16a, a second terminal 16b, and a third terminal 16c. These terminals 16a, 16b, and 16c are arranged at predetermined positions so as to face the outside of the housing 15. The first terminal 16a and the second terminal 16b are electrically connected.

発光素子17は、例えばＬＥＤが用いられており、アノード側が第２端子16bに接続され、カソード側が第３端子16cに接続されている。発光素子17は、１つでもよいし、複数の発光素子17が直列に接続あるいは直並列に接続されていてもよい。 As the light emitting element 17, for example, an LED is used, and the anode side is connected to the second terminal 16b and the cathode side is connected to the third terminal 16c. The number of light emitting elements 17 may be one, or a plurality of light emitting elements 17 may be connected in series or in series and parallel.

次に、点灯装置12は、例えば光源11を着脱可能に装着するソケットを有する器具側に配設されている。 Next, the lighting device 12 is arranged on the appliance side having a socket for detachably mounting the light source 11, for example.

点灯装置12は、直流電源を供給する直流電源部20、光源11と電気的に接続される端子部（回路側端子部）21、直流電源部20と端子部21との間に接続され直流電源を点灯電源に変換して光源11に供給する点灯回路22、光源11の装着有無を検出する装着検出回路23、光源11に流れる電流を検出する電流検出部24、および装着検出回路23で検出される装着情報や電流検出部24で検出される電流に応じて点灯回路22を制御する制御部25を備えている。 The lighting device 12 is connected to a DC power supply unit 20 that supplies DC power, a terminal unit (circuit side terminal unit) 21 that is electrically connected to the light source 11, and a DC power supply that is connected between the DC power supply unit 20 and the terminal unit 21. Is detected by the lighting circuit 22 that converts the current into a lighting power source and supplies it to the light source 11, the mounting detection circuit 23 that detects whether or not the light source 11 is mounted, the current detection unit 24 that detects the current flowing through the light source 11, and the mounting detection circuit 23. It is provided with a control unit 25 that controls the lighting circuit 22 according to the mounting information and the current detected by the current detection unit 24.

直流電源部20は、直流電源を点灯回路22に供給するものであって、例えば交流電源を整流、平滑した直流電源を点灯回路22に供給する。 The DC power supply unit 20 supplies a DC power supply to the lighting circuit 22, for example, rectifying an AC power supply and supplying a smoothed DC power supply to the lighting circuit 22.

また、端子部21は、第１端子21a、第２端子21bおよび第３端子21cを備えている。これら第１端子21a、第２端子21bおよび第３端子21cは、例えば光源11を着脱可能に装着するソケットに配設され、ソケットに装着された光源11の対応する第１端子16a、第２端子16bおよび第３端子16cと電気的に接続されるように構成されている。 Further, the terminal portion 21 includes a first terminal 21a, a second terminal 21b, and a third terminal 21c. The first terminal 21a, the second terminal 21b, and the third terminal 21c are arranged in, for example, a socket to which the light source 11 is detachably mounted, and the corresponding first terminal 16a and the second terminal of the light source 11 mounted in the socket are arranged. It is configured to be electrically connected to the 16b and the third terminal 16c.

また、点灯回路22は、降圧チョッパ回路によって構成されている。点灯回路22は、直流電源部20の両端間に接続されたスイッチング素子28およびダイオード29の直列回路、これらスイッチング素子28とダイオード29との接続点に一端側が接続されたインダクタ30、およびこのインダクタ30の他端側で第１端子21aと第３端子21cとの間に並列に接続されたコンデンサ31を備えている。 Further, the lighting circuit 22 is composed of a step-down chopper circuit. The lighting circuit 22 is a series circuit of a switching element 28 and a diode 29 connected between both ends of the DC power supply unit 20, an inductor 30 having one end connected to a connection point between the switching element 28 and the diode 29, and the inductor 30. A capacitor 31 connected in parallel between the first terminal 21a and the third terminal 21c is provided on the other end side of the above.

スイッチング素子28は、直流電源の高電位側でスイッチングを行うもので、例えば電界効果トランジスタ（ＭＯＳＦＥＴ）が用いられている。電界効果トランジスタのドレイン電極が直流電源部20の高電位側に接続され、ソース電極がダイオード29のカソード側およびインダクタ30に接続され、ゲート電極が制御部25に接続されている。 The switching element 28 switches on the high potential side of the DC power supply, and for example, a field effect transistor (MOSFET) is used. The drain electrode of the field effect transistor is connected to the high potential side of the DC power supply unit 20, the source electrode is connected to the cathode side of the diode 29 and the inductor 30, and the gate electrode is connected to the control unit 25.

ダイオード29は、アノード側が接地され、カソード側がスイッチング素子28およびインダクタ30に接続されている。このダイオード29は、スイッチング素子28がオフのときに、インダクタ30、コンデンサ31および光源11により閉回路を形成するように構成されている。 The anode side of the diode 29 is grounded, and the cathode side is connected to the switching element 28 and the inductor 30. The diode 29 is configured to form a closed circuit with an inductor 30, a capacitor 31 and a light source 11 when the switching element 28 is off.

コンデンサ31は、点灯回路22の出力電圧を平滑する平滑コンデンサが用いられている。 As the capacitor 31, a smoothing capacitor that smoothes the output voltage of the lighting circuit 22 is used.

また、装着検出回路23は、点灯回路22の出力側において第１端子21a側である高電位側と接地側である低電位側との間に直列に接続された分圧抵抗33，34、第２端子21bと第３端子21cとの間に接続された装着検出用抵抗35、分圧抵抗33と分圧抵抗34との接続点に接続された装着検出部36、定電圧源37、定電圧源37と分圧抵抗33の高電位側との間に接続される抵抗38とダイオード39とで構成された直列回路を備えている。装着検出用抵抗35は、第２端子21bと第３端子21cとの間に接続されている。したがって、光源11が装着されている状態では、分圧抵抗33，34と装着検出用抵抗35とが並列に接続されるように構成されている。 Further, the mounting detection circuit 23 has the voltage dividing resistors 33, 34, and the third voltage dividing resistors 33, 34, which are connected in series between the high potential side which is the first terminal 21a side and the low potential side which is the ground side on the output side of the lighting circuit 22. A mounting detection resistor 35 connected between the 2nd terminal 21b and the 3rd terminal 21c, a mounting detection unit 36 connected to the connection point between the voltage dividing resistor 33 and the voltage dividing resistor 34, a constant voltage source 37, and a constant voltage. It has a series circuit composed of a resistor 38 and a diode 39 connected between the source 37 and the high potential side of the voltage dividing resistor 33. The mounting detection resistor 35 is connected between the second terminal 21b and the third terminal 21c. Therefore, when the light source 11 is mounted, the voltage dividing resistors 33 and 34 and the mounting detection resistor 35 are configured to be connected in parallel.

装着検出部36は、例えばマイコンによって構成されている。装着検出部36は、分圧抵抗33，34を介して入力する検出電圧値と予め設定された閾値とを比較し、検出電圧値が閾値よりも小さければ光源11の装着有と判断し、検出電圧値が閾値よりも大きければ光源11の装着無と判断し、判断結果を制御部25に出力する。 The mounting detection unit 36 is composed of, for example, a microcomputer. The mounting detection unit 36 compares the detection voltage value input via the voltage dividing resistors 33 and 34 with the preset threshold value, and if the detection voltage value is smaller than the threshold value, determines that the light source 11 is mounted and detects it. If the voltage value is larger than the threshold value, it is determined that the light source 11 is not attached, and the determination result is output to the control unit 25.

なお、装着検出部36は、制御部25が備えていてもよい。 The mounting detection unit 36 may be provided by the control unit 25.

さらに、装着検出回路23による装着検知時には、検出用電源供給部である定電圧源37から例えば１５Ｖ程度の検出用電源を点灯回路22の出力側に供給する。定電圧源37は、端子部21に接続される光源11が点灯しない、すなわち発光素子17が点灯しない所定値未満の電圧を供給する。なお、定電圧源37は、点灯回路22によって兼用してもよい。 Further, at the time of mounting detection by the mounting detection circuit 23, a detection power supply of, for example, about 15 V is supplied to the output side of the lighting circuit 22 from the constant voltage source 37 which is the detection power supply unit. The constant voltage source 37 supplies a voltage less than a predetermined value in which the light source 11 connected to the terminal portion 21 does not light, that is, the light emitting element 17 does not light. The constant voltage source 37 may also be used by the lighting circuit 22.

また、電流検出部24は、直流電源の低電位側に接続される検出抵抗41を備え、この検出抵抗41を介して光源11に流れる電流を検出して制御部25に出力する。 Further, the current detection unit 24 includes a detection resistor 41 connected to the low potential side of the DC power supply, detects the current flowing through the light source 11 through the detection resistor 41, and outputs the current to the control unit 25.

また、制御部25は、例えば制御ＩＣによって構成されている。制御部25は、装着検出部36からの光源11の装着有の判断結果を入力したときには点灯回路22を起動し、装着検出部36からの光源11の装着無の判断結果を入力したときには点灯回路22を起動させないか、出力を通常の点灯時よりも小さくする。制御部25は、点灯回路22の起動後に、電流検出部24で検出される検出電流に応じて、スイッチング素子28のスイッチング動作をフィードバック制御する。 Further, the control unit 25 is composed of, for example, a control IC. The control unit 25 activates the lighting circuit 22 when the determination result of whether or not the light source 11 is attached is input from the attachment detection unit 36, and the lighting circuit when the determination result of whether or not the light source 11 is attached is input from the attachment detection unit 36. Do not start 22 or make the output smaller than when it is normally lit. After the lighting circuit 22 is activated, the control unit 25 feedback-controls the switching operation of the switching element 28 according to the detection current detected by the current detection unit 24.

そして、点灯装置12の動作を説明する。 Then, the operation of the lighting device 12 will be described.

点灯装置12の起動時、検出用電源部から１５Ｖ程度の検出用電源を点灯回路22の出力側に供給する。 When the lighting device 12 is started, a detection power supply of about 15 V is supplied from the detection power supply unit to the output side of the lighting circuit 22.

装着検出部36は、分圧抵抗33，34を介して入力する検出電圧値と予め設定された閾値とを比較し、装着有無の結果を制御部25に出力する。 The mounting detection unit 36 compares the detection voltage value input via the voltage dividing resistors 33 and 34 with the preset threshold value, and outputs the result of mounting / not wearing to the control unit 25.

ここで、光源11が装着されていなかった場合、第１端子21aと第２端子21bとの間が開放されて装着検出用抵抗35は接続されず、装着検出部36には分圧抵抗33，34で分圧された検出用電源が入力されるため、装着検出部36では検出電圧値が閾値よりも大きくなって光源11の装着無と判断する。 Here, when the light source 11 is not mounted, the space between the first terminal 21a and the second terminal 21b is opened and the mounting detection resistor 35 is not connected, and the voltage dividing resistor 33 is connected to the mounting detection unit 36. Since the detection power supply divided by 34 is input, the mounting detection unit 36 determines that the light source 11 is not mounted because the detection voltage value becomes larger than the threshold value.

一方、光源11が装着されていた場合、第１端子21aと第２端子21bとの間が光源11側で接続されて装着検出用抵抗35が接続され、分圧抵抗33，34と装着検出用抵抗35とが並列に接続されることにより、装着検出部36に入力される検出用電源が電圧降下し、装着検出部36では検出電圧値が閾値よりも小さくなって光源11の装着有と判断する。 On the other hand, when the light source 11 is mounted, the first terminal 21a and the second terminal 21b are connected on the light source 11 side to connect the mounting detection resistor 35, and the voltage dividing resistors 33 and 34 and the mounting detection are connected. When the resistor 35 is connected in parallel, the voltage of the detection power supply input to the mounting detection unit 36 drops, and the detection voltage value of the mounting detection unit 36 becomes smaller than the threshold value, and it is determined that the light source 11 is mounted. To do.

そして、制御部25は、装着検出部36から装着有の信号を入力すると、点灯回路22を起動し、スイッチング素子28をスイッチング動作させる。 Then, when the control unit 25 inputs a signal with mounting from the mounting detection unit 36, the control unit 25 activates the lighting circuit 22 and switches the switching element 28.

一方、制御部25は、装着検出部36から装着無の信号を入力すると、点灯回路22を起動しない。 On the other hand, the control unit 25 does not activate the lighting circuit 22 when a signal of no attachment is input from the attachment detection unit 36.

そして、点灯回路22が起動すると、直流電源部20から点灯回路22に直流電源を供給する。点灯回路22では、制御部25によってスイッチング素子28のスイッチング動作を制御し、直流電源を降圧し、発光素子17に供給する。 Then, when the lighting circuit 22 is activated, the DC power supply unit 20 supplies DC power to the lighting circuit 22. In the lighting circuit 22, the control unit 25 controls the switching operation of the switching element 28, steps down the DC power supply, and supplies the DC power supply to the light emitting element 17.

スイッチング素子28のオン時には、直流電源部20の高電位側からの電流が、スイッチング素子28、インダクタ30、発光素子17を通じて、直流電源部20の低電位側に流れる。このとき、発光素子17にはコンデンサ31で平滑された電流が流れ、発光素子17は一定の明るさで点灯する。 When the switching element 28 is turned on, a current from the high potential side of the DC power supply unit 20 flows to the low potential side of the DC power supply unit 20 through the switching element 28, the inductor 30, and the light emitting element 17. At this time, a current smoothed by the capacitor 31 flows through the light emitting element 17, and the light emitting element 17 lights up with a constant brightness.

スイッチング素子28のオフ時には、インダクタ30に蓄えられた電流が放出され、発光素子17、ダイオード29を通じて閉回路内を流れる。このとき、発光素子17にはコンデンサ31で平滑された電流が流れ、発光素子17は一定の明るさで点灯する。 When the switching element 28 is off, the current stored in the inductor 30 is released and flows through the light emitting element 17 and the diode 29 in the closed circuit. At this time, a current smoothed by the capacitor 31 flows through the light emitting element 17, and the light emitting element 17 lights up with a constant brightness.

また、制御部25は、電流検出部24で検出される検出電流に基づいてスイッチング素子28のスイッチング動作をフィードバック制御する。 Further, the control unit 25 feedback-controls the switching operation of the switching element 28 based on the detection current detected by the current detection unit 24.

そして、本実施形態によれば、光源11が検出抵抗を備えなくても、光源11の装着有無を検出することができる。 Then, according to this embodiment, it is possible to detect whether or not the light source 11 is attached even if the light source 11 does not have a detection resistor.

すなわち、点灯回路22が第１端子21a、第２端子21bおよび第３端子21cの３点で光源11と接続する構成とし、第１端子21aおよび第３端子21cに点灯回路22の出力側を接続するとともに、第２端子21bと第３端子21cとの間に装着検出用抵抗35を接続しておくことにより、光源11の装着時には、第１端子21aと第２端子21bとの間が光源11で接続され、第２端子21bと第３端子21cとの間に発光素子17を接続することができる。このような接続の構成により、装着検出部36では、第１端子21a側および装着検出用抵抗35に接続されて電圧を検出し、光源11の装着有無に応じて変化する電圧値によって光源11の装着有無を検出することができる。 That is, the lighting circuit 22 is configured to be connected to the light source 11 at three points of the first terminal 21a, the second terminal 21b, and the third terminal 21c, and the output side of the lighting circuit 22 is connected to the first terminal 21a and the third terminal 21c. At the same time, by connecting the mounting detection resistor 35 between the second terminal 21b and the third terminal 21c, when the light source 11 is mounted, the light source 11 is between the first terminal 21a and the second terminal 21b. The light source 17 can be connected between the second terminal 21b and the third terminal 21c. With such a connection configuration, the mounting detection unit 36 is connected to the first terminal 21a side and the mounting detection resistor 35 to detect the voltage, and the light source 11 has a voltage value that changes depending on whether or not the light source 11 is mounted. It is possible to detect the presence or absence of wearing.

そのため、光源11は検出抵抗を備えなくてよいため、交換可能な光源11を簡素化できたり、光源11の低価格化に対応できる。 Therefore, since the light source 11 does not have to have a detection resistor, the replaceable light source 11 can be simplified and the price of the light source 11 can be reduced.

なお、点灯回路22は、降圧チョッパ回路のみを用いた降圧チョッパ回路方式であってもよいし、降圧チョッパ回路と力率改善回路とを組み合わせた回路構成でもよく、あるいは他の電源変換回路を備えた回路構成でもよい。 The lighting circuit 22 may be a step-down chopper circuit system using only a step-down chopper circuit, may have a circuit configuration in which a step-down chopper circuit and a power factor improving circuit are combined, or may include another power conversion circuit. The circuit configuration may be used.
