本實施例的開關裝置1具有上述之配置，且後文中描述了開關裝置1之操作。The switching device 1 of the present embodiment has the above configuration, and the operation of the switching device 1 is described later.
首先，描述當人類感測器70的偵測區域中沒有人時開關裝置1的操作。First, the operation of the switching device 1 when there is no person in the detection area of the human sensor 70 will be described.
當人類感測器70的偵測區域中沒有人時，則信號處理單元40不會從人類感測器70接收到偵測信號。信號處理單元40執行以下操作以關閉照明負載300並停止風扇負載400。When there is no person in the detection area of the human sensor 70, the signal processing unit 40 does not receive the detection signal from the human sensor 70. The signal processing unit 40 performs the following operations to turn off the lighting load 300 and stop the fan load 400.
當人類感測器70不將偵測信號輸入時，信號處理單元40將輸出埠P1、P2、及P3的所有電壓位準設定至低位準、並關閉所有的開關元件21、22、及52。在此情況下，電流不流過繼電器線圈102及112，且接點101及111兩者皆處在關閉狀態。電流亦不流過LED 511，且雙向閘流體512處於關閉狀態，使得雙向閘流體12處於關閉狀態。因此，當人類感測器70的偵測區域中沒有人時，照明負載300被關閉且風扇負載400被停止。當所有的開關元件21、22、及52處在關閉狀態時，基極電流不流過電晶體31且電晶體 31係處於關閉狀態。在整流器DB1的輸出電壓高於稽納二極體ZD1的稽納電壓的期間內，電流從整流器DB1經由電阻器R6及稽納二極體 ZD1而流動 。在這裡，第二電流路徑RT2係由電阻器R6及稽納二極體ZD1所形成、且驅使來自AC電源200的電流以第二狀態(在此狀態中激磁電流不流過繼電器線圈102及112)流動。第二電流路徑RT2連接至電阻器R6以限制流過第二電流路徑RT2之電流。When the human sensor 70 does not input the detection signal, the signal processing unit 40 sets all the voltage levels of the outputs 埠P1, P2, and P3 to the low level, and turns off all of the switching elements 21, 22, and 52. In this case, current does not flow through the relay coils 102 and 112, and both of the contacts 101 and 111 are in a closed state. The current also does not flow through the LED 511, and the bidirectional thyristor 512 is in a closed state such that the bidirectional thyristor 12 is in a closed state. Therefore, when there is no person in the detection area of the human sensor 70, the lighting load 300 is turned off and the fan load 400 is stopped. When all of the switching elements 21, 22, and 52 are in the off state, the base current does not flow through the transistor 31 and the transistor 31 is in the off state. During a period in which the output voltage of the rectifier DB1 is higher than the Zener voltage of the Zener diode ZD1, a current flows from the rectifier DB1 via the resistor R6 and the sense diode ZD1. Here, the second current path RT2 is formed by the resistor R6 and the sense diode ZD1, and drives the current from the AC power source 200 in the second state (in this state, the excitation current does not flow through the relay coils 102 and 112). )flow. The second current path RT2 is coupled to the resistor R6 to limit the current flowing through the second current path RT2.
接下來，描述當人類感測器70的偵測區域中有人時開關裝置1的操作。Next, the operation of the switching device 1 when there is a person in the detection area of the human sensor 70 will be described.
當人類感測器70的偵測區域中有人且人類感測器70將偵測信號輸入至信號處理單元40時，信號處理單元40執行下列操作以開啟照明負載300並使風扇負載400執行換氣。When a person in the detection area of the human sensor 70 and the human sensor 70 input a detection signal to the signal processing unit 40, the signal processing unit 40 performs the following operations to turn on the illumination load 300 and cause the fan load 400 to perform ventilation. .
信號處理單元40首先在將輸出埠P1的電壓位準保持在低位準的同時將輸出埠P2及P3的電壓位準從低位準切換至高位準。此時，開關元件21被保持在關閉狀態，且開關元件22及52被從關閉狀態切換至開啟狀態。The signal processing unit 40 first switches the voltage levels of the outputs 埠P2 and P3 from a low level to a high level while maintaining the voltage level of the output 埠P1 at a low level. At this time, the switching element 21 is maintained in the off state, and the switching elements 22 and 52 are switched from the off state to the on state.
當開關元件22開啟時，基極電流流過電晶體31以將電晶體31從關閉狀態切換至開啟狀態，且電容器C4將來自整流器 DB1之脈動電壓輸入平滑化 。此時，電流從電容器C4依序流過繼電器線圈112、電阻器R11、及開關元件22，使得激磁電流流過繼電器線圈112以開啟繼電器11的接點111。當接點111開啟時，AC電源200經由接點111而將AC電流提供至風扇負載400、且風扇負載400使馬達旋轉以執行換氣。When the switching element 22 is turned on, the base current flows through the transistor 31 to switch the transistor 31 from the off state to the on state, and the capacitor C4 smoothes the ripple voltage input from the rectifier DB1. At this time, current flows from the capacitor C4 through the relay coil 112, the resistor R11, and the switching element 22 in order, so that the exciting current flows through the relay coil 112 to open the contact 111 of the relay 11. When the contact 111 is turned on, the AC power source 200 supplies AC current to the fan load 400 via the contact 111, and the fan load 400 rotates the motor to perform ventilation.
當開關元件52開啟時，電流從電容器C4依序流過電阻器R7、發光二極體511、及開關元件52，且雙向閘流體512在AC電源200所輸入之AC電壓的零交越點被從關閉狀態切換至開啟狀態。當雙向閘流體512開啟時，較導通電壓(break over voltage)更高的電壓被施加至雙向閘流體12的閘極終端(閘極電極)G1且雙向閘流體12被從關閉狀態切換至開啟狀態。當雙向閘流體12開啟時，AC電力從AC電源200經由雙向閘流體12供應至照明負載300以開啟照明負載300。When the switching element 52 is turned on, current flows from the capacitor C4 through the resistor R7, the light emitting diode 511, and the switching element 52, and the bidirectional thyristor 512 is at the zero crossing point of the AC voltage input by the AC power source 200. Switch from off state to on state. When the two-way thyristor 512 is turned on, a voltage higher than a break over voltage is applied to the gate terminal (gate electrode) G1 of the bidirectional thyristor 12 and the bidirectional thyristor 12 is switched from the off state to the on state. . When the two-way thyristor 12 is turned on, AC power is supplied from the AC power source 200 to the lighting load 300 via the two-way thyristor 12 to turn on the lighting load 300.
在這裡，照明負載300為電阻性負載 。因此，當雙向閘流體12開啟時，衝擊電流(rush current)從AC電源200流動至照明負載300。當照明負載300開啟時，衝擊電流不流動通過繼電器10之接點101，而是通過做為半導體開關的雙向閘流體12。換言之，當照明負載300開啟時，由於接點101處於關閉狀態且雙向閘流體12被開啟，衝擊電流流過雙向閘流體12。因此，吾人可保護接點101。風扇負載400為電感性負載，且接點111被開啟時衝擊電流不流入風扇負載400中。因此，雙向閘流體不並聯連接至接點111，且被運載至風扇負載400之電流僅被接點111開啟及關閉。Here, the lighting load 300 is a resistive load. Therefore, when the two-way thyristor 12 is turned on, a rush current flows from the AC power source 200 to the illumination load 300. When the lighting load 300 is turned on, the inrush current does not flow through the contact 101 of the relay 10, but through the bidirectional thyristor 12 as a semiconductor switch. In other words, when the lighting load 300 is turned on, an inrush current flows through the bidirectional thyristor 12 since the contact 101 is in the off state and the bidirectional thyristor 12 is turned on. Therefore, we can protect the contact 101. The fan load 400 is an inductive load, and the inrush current does not flow into the fan load 400 when the contact 111 is turned on. Therefore, the two-way thyristor is not connected in parallel to the contact 111, and the current carried to the fan load 400 is only turned on and off by the contact 111.
在從雙向閘流體12從關閉狀態切換至開啟狀態的時間起一預設第一延遲期間過去之後，信號處理單元40將輸出埠P1的電壓位準從低位準切換至高位準。此時，開關元件21被從關閉狀態切換至開啟狀態以使激磁電流流過繼電器線圈102，使得接點101開啟。在從接點101從關閉狀態切換至開啟狀態的時間起經過了一預設第二延遲期間之後，信號處理單元40將輸出埠P3的電壓位準從高位準切換至低位準。此時，開關元件52從開啟狀態切換至關閉狀態以停止通過LED 511之電流流動，使得雙向閘流體512被關閉。當雙向閘流體512被關閉時，雙向閘流體12被關閉且電流僅經由接點101而從AC電源200流動至照明負載300。第一延遲期間只需要設定得較照明負載300開啟時衝擊電流流動的期間稍長，例如約一秒鐘。第二延遲期間只需要設定得較所需要的操作期間(從繼電器線圈102運載電流的時間至接點101閉合的時間)稍長、並根據繼電器10之操作性能而設置在適當期間。After a predetermined first delay period elapses from the time when the two-way thyristor 12 is switched from the off state to the on state, the signal processing unit 40 switches the voltage level of the output 埠P1 from the low level to the high level. At this time, the switching element 21 is switched from the off state to the on state to cause the exciting current to flow through the relay coil 102, so that the contact 101 is turned on. After a predetermined second delay period elapses from the time when the contact 101 is switched from the off state to the on state, the signal processing unit 40 switches the voltage level of the output 埠P3 from the high level to the low level. At this time, the switching element 52 is switched from the on state to the off state to stop the flow of current through the LED 511, so that the bidirectional thyristor 512 is turned off. When the two-way thyristor 512 is turned off, the two-way thyristor 12 is turned off and current flows from the AC power source 200 to the lighting load 300 only via the contacts 101. The first delay period only needs to be set slightly longer than the period during which the inrush current flows when the illumination load 300 is turned on, for example, about one second. The second delay period only needs to be set slightly longer than the required operation period (the time from when the relay coil 102 carries the current to the time when the contact 101 is closed), and is set to an appropriate period in accordance with the operational performance of the relay 10.
因此，當人類感測器70偵測到人時，開關裝置1將照明負載300開啟並使風扇負載400執行換氣。開關裝置1藉由將雙向閘流體12從關閉狀態切換至開啟狀態而開啟照明負載300，使得於該開啟步驟的開頭流動的衝擊電流所造成的接點101之熔接被抑制。在從照明負載300開啟的時間起經過了第一延遲期間及第二延遲期間之後，開關裝置1使電流經由接點101流動至照明負載300。因此，可降低電流運載所導致的雙向閘流體12之熱產生、或在雙向閘流體12中的功率損耗。Therefore, when the human sensor 70 detects a person, the switching device 1 turns on the lighting load 300 and causes the fan load 400 to perform the ventilation. The switching device 1 turns on the illumination load 300 by switching the bidirectional thyristor 12 from the off state to the on state, so that the fusion of the contacts 101 caused by the inrush current flowing at the beginning of the opening step is suppressed. The switching device 1 causes a current to flow to the lighting load 300 via the contact 101 after the first delay period and the second delay period have elapsed since the lighting load 300 was turned on. Therefore, the heat generation of the two-way thyristor 12 caused by the current carrying or the power loss in the two-way thyristor 12 can be reduced.
在使激磁電流流過繼電器線圈102及112的第一狀態中，激磁電流從整流器DB1經由稽納二極體ZD2及電晶體31流動至繼電器線圈102及112。在本實施例中，電容器C4係連接在電晶體31的射極與該電路的接地端之間，使得經由稽納二極體ZD2及電晶體31而從整流器DB1輸入之電壓被電容器C4平滑化至基本上恆定的電壓。藉由電容器C4而平滑化的電壓被施加至繼電器線圈102及112，使得吾人可使穩定的電流流過繼電器線圈102及112。在這裡，稽納二極體ZD2及電晶體31構成了第一電流路徑RT1，電流通過該第一電流路徑而從AC電源200流動至第一驅動電路20。不同於該第一電流路徑RT1，第二電流路徑RT2包括了電阻器R6，使得第二電流路徑RT2的阻抗高於第一電流路徑RT1的阻抗。因此，相較於使激磁電流流動通過繼電器線圈102及112的第一狀態，在不使激磁電流流動通過繼電器線圈102及112的第二狀態中可抑制從AC電源200流入開關電路30的電流、並可降低待機功率。In the first state in which the exciting current flows through the relay coils 102 and 112, the exciting current flows from the rectifier DB1 to the relay coils 102 and 112 via the Zener diode ZD2 and the transistor 31. In the present embodiment, the capacitor C4 is connected between the emitter of the transistor 31 and the ground of the circuit, so that the voltage input from the rectifier DB1 via the gate diode ZD2 and the transistor 31 is smoothed by the capacitor C4. To a substantially constant voltage. The voltage smoothed by the capacitor C4 is applied to the relay coils 102 and 112 so that a steady current can flow through the relay coils 102 and 112. Here, the Zener diode ZD2 and the transistor 31 constitute a first current path RT1 through which current flows from the AC power source 200 to the first drive circuit 20. Unlike the first current path RT1, the second current path RT2 includes the resistor R6 such that the impedance of the second current path RT2 is higher than the impedance of the first current path RT1. Therefore, compared with the first state in which the exciting current flows through the relay coils 102 and 112, the current flowing from the AC power source 200 to the switching circuit 30 can be suppressed in the second state in which the exciting current does not flow through the relay coils 102 and 112, And can reduce standby power.
接下來，描述當所有人在照明負載300開啟且風扇負載400正執行換氣的狀態中離開人類感測器70之偵測區域時開關裝置1的操作。Next, the operation of the switching device 1 when the person leaves the detection area of the human sensor 70 in a state where the lighting load 300 is turned on and the fan load 400 is performing the ventilation is described.
當所有人離開人類感測器70的偵測區域時，從人類感測器70至信號處理單元40的偵測信號之輸入停止。在從偵測信號之輸入停止的時間起經過了一預設操作保持期間之後，信號處理單元40執行以下操作以關閉照明負載300並停止風扇負載400。When all the person leaves the detection area of the human sensor 70, the input of the detection signal from the human sensor 70 to the signal processing unit 40 is stopped. After a predetermined operation holding period elapses from the time when the input of the detection signal is stopped, the signal processing unit 40 performs the following operations to turn off the lighting load 300 and stop the fan load 400.
從來自人類感測器70的偵測信號之輸入停止的時間起經過了該操作保持期間之後，信號處理單元40將輸出埠P1及P2的電壓位準從高位準切換至低位準。信號處理單元40將輸出埠P3的電壓位準保持在低位準。在此情況下，電流不流過繼電器線圈102及112，接點101及111從開啟狀態切換至關閉狀態，照明負載300被關閉，且藉由風扇負載400而進行之換氣被停止。After the operation holding period elapses from the time when the input of the detection signal from the human sensor 70 is stopped, the signal processing unit 40 switches the voltage levels of the outputs 埠P1 and P2 from the high level to the low level. The signal processing unit 40 maintains the voltage level of the output 埠P3 at a low level. In this case, current does not flow through the relay coils 102 and 112, the contacts 101 and 111 are switched from the on state to the off state, the illumination load 300 is turned off, and the ventilation by the fan load 400 is stopped.
在這裡，風扇負載400為電感性負載，使得當對風扇負載400之電源供應中斷時風扇負載400中發生了約為額定電壓的好幾倍大之反電動勢。Here, the fan load 400 is an inductive load such that a counter-electromotive force that is several times larger than the rated voltage occurs in the fan load 400 when the power supply to the fan load 400 is interrupted.
當開關裝置1不包括突波吸收電路60、且連接至負載終端94的導線與連接至負載終端95的導線之間產生雜散電容(由於該等導線係在彼此附近)時，已於風扇負載400中發生的反電動勢可進入光耦合器51中。當已於風扇負載400中發生的反電動勢進入光耦合器51中、且高於導通電壓之電壓被施加至雙向閘流體512時，雙向閘流體512及雙向閘流體 12被開啟一短暫時間。照明負載300包括一LED(作為光源)，該LED具有較白熾燈的回應性更高之回應性，使得照明負載300可被雙向閘流體512及雙向閘流體12之短時間的開啟狀態短暫地開啟。當雙向閘流體12的耐受電壓低於光耦合器51的雙向閘流體512之耐受電壓時，雙向閘流體12在雙向閘流體512之前先被接點111關閉時風扇負載400中發生的反電動勢所開啓。When the switching device 1 does not include the surge absorbing circuit 60, and the stray capacitance is generated between the wires connected to the load terminal 94 and the wires connected to the load terminal 95 (because the wires are in proximity to each other), the fan load is applied. The counter electromotive force occurring in 400 can enter the optical coupler 51. When the counter electromotive force that has occurred in the fan load 400 enters the photocoupler 51 and a voltage higher than the on-voltage is applied to the bidirectional thyristor 512, the bidirectional thyristor 512 and the bidirectional thyristor 12 are turned on for a short time. The lighting load 300 includes an LED (as a light source) that has a higher responsiveness to the blazing lamp, such that the lighting load 300 can be briefly turned on by the short-circuiting of the bi-directional thyristor 512 and the bi-directional thyristor 12 . When the withstand voltage of the bidirectional thyristor 12 is lower than the withstand voltage of the bidirectional thyristor 512 of the optocoupler 51, the reversal occurs in the fan load 400 when the bidirectional thyristor 12 is first turned off by the contact 111 before the bidirectional thyristor 512 The electromotive force is turned on.
在本實施例的開關裝置1中，由電阻器R4與電容器C2之串聯電路所形成的突波吸收電路60以並聯連接至雙向閘流體12。換言之，突波吸收電路60以並聯連接至電阻器R2、雙向閘流體512、與電阻器R3的串聯電路。因此，即使一反電動勢於接點111被關閉時在風扇負載400中發生，但電壓之上升變得平緩、且施加至包括了雙向閘流體12之第二開關元件的突波電壓被藉由透過電阻器R4對電容器C2進行充電而降低。因此，在風扇負載400中發生之反電動勢較不易引起雙向閘流體512與雙向閘流體12之導通、且較不易引起照明負載300被短暫地點亮之情況。突波吸收電路60不限於電阻器R4與電容器C4之RC串聯電路。突波吸收電路60可為其它電路配置或變阻器。In the switching device 1 of the present embodiment, the surge absorbing circuit 60 formed by the series circuit of the resistor R4 and the capacitor C2 is connected in parallel to the bidirectional thyristor 12. In other words, the surge absorbing circuit 60 is connected in parallel to the series circuit of the resistor R2, the bidirectional thyristor 512, and the resistor R3. Therefore, even if a counter electromotive force occurs in the fan load 400 when the contact 111 is closed, the rise in voltage becomes gentle, and the surge voltage applied to the second switching element including the bidirectional thyristor 12 is transmitted through Resistor R4 reduces capacitor C2 by charging it. Therefore, the counter electromotive force occurring in the fan load 400 is less likely to cause the conduction of the bidirectional thyristor 512 and the bidirectional thyristor 12, and is less likely to cause the illumination load 300 to be briefly illuminated. The surge absorbing circuit 60 is not limited to the RC series circuit of the resistor R4 and the capacitor C4. The surge absorbing circuit 60 can be other circuit configurations or varistors.
如上面所述，本實施例之開關裝置1包括了連接至第一負載(風扇負載400)的第一終端(負載終端95及96)、及連接至第二負載(照明負載300)的第二終端(負載終端93及94)。開關裝置1包括了第一開關元件(繼電器11的接點111)、及第二開關元件，其中該第一開關元件***在將AC電源200連接至第一負載的電氣路徑中且電氣連接至該電氣路徑、及該第二開關元件***在將AC電源200連接至第二負載的電氣路徑中且電氣連接至該電氣路徑。第二開關元件包括了為半導體開關之雙向閘流體12及雙向閘流體512。用以減少施加至第二開關元件之突波電壓的突波吸收元件(突波吸收電路60)連接在AC電源200與第二負載之間而與第二開關元件並聯。As described above, the switching device 1 of the present embodiment includes a first terminal (load terminals 95 and 96) connected to the first load (fan load 400), and a second terminal (lighting load 300) connected to the second load (lighting load 300) Terminal (load terminals 93 and 94). The switching device 1 includes a first switching element (contact 111 of the relay 11) and a second switching element, wherein the first switching element is inserted in an electrical path connecting the AC power source 200 to the first load and electrically connected to the An electrical path, and the second switching element, are inserted in an electrical path connecting the AC power source 200 to the second load and electrically connected to the electrical path. The second switching element includes a bidirectional thyristor 12 and a bidirectional thyristor 512 that are semiconductor switches. A surge absorbing element (surge absorbing circuit 60) for reducing a surge voltage applied to the second switching element is connected between the AC power source 200 and the second load in parallel with the second switching element.
因此，即使當第一開關元件將對第一負載的電源供應中斷時於第一負載中所發生的反電動勢進入了第二開關元件，施加至第二開關元件的突波電壓仍可被該突波吸收元件降低。因此，在第一負載中發生的反電動勢較不易引起在第二開關元件的開啟與關閉之間的切換、且為較不易引起第二負載短暫地操作之情況。Therefore, even when the back electromotive force generated in the first load enters the second switching element when the first switching element interrupts the power supply to the first load, the surge voltage applied to the second switching element can be blocked The wave absorbing element is lowered. Therefore, the counter electromotive force occurring in the first load is less likely to cause switching between the opening and closing of the second switching element, and is less likely to cause the second load to operate briefly.
在本實施例的開關裝置1中，較佳地，突波吸收元件(突波吸收電路60)係用以將突波電壓降低至較半導體開關之導通電壓更低的值。藉由利用突波吸收元件而將突波電壓降低至較導通電壓更低的值，半導體開關被突波電壓開啟一短暫時間的情況被抑制。In the switching device 1 of the present embodiment, preferably, the surge absorbing element (surge absorbing circuit 60) is for lowering the surge voltage to a value lower than the turn-on voltage of the semiconductor switch. By using the surge absorbing element to lower the surge voltage to a value lower than the turn-on voltage, the semiconductor switch is suppressed by the surge voltage for a short period of time.
在本實施例的開關裝置1中，第一負載可為電感性負載(本實施例中的風扇負載400)。當對電感性負載的電源供應被中斷時，電感性負載中發生反電動勢。即使該反電動勢進入第二開關元件中，突波吸收元件仍降低了施加至第二開關元件的突波電壓，因此在第二開關元件的開啟與關閉之間的切換被抑制。In the switching device 1 of the present embodiment, the first load may be an inductive load (the fan load 400 in this embodiment). When the power supply to the inductive load is interrupted, a back electromotive force occurs in the inductive load. Even if the counter electromotive force enters the second switching element, the surge absorbing element reduces the surge voltage applied to the second switching element, so switching between the opening and closing of the second switching element is suppressed.
在本實施例的開關裝置1中，第二負載可為照明負載300(例如，LED照明器)。即使當對第一負載的電源供應被中斷時於該第一負載中所發生之反電動勢進入第二開關元件中，但突波吸收元件降低了施加至第二開關元件的突波電壓，因此在第二開關元件的開啟與關閉之間的切換被抑制。因此，即使當第二負載為具有高回應性的LED照明器時，對第一負載的電源供應被中斷時LED照明器被短暫地點亮之情況仍被抑制。In the switching device 1 of the present embodiment, the second load may be a lighting load 300 (eg, an LED illuminator). Even if the counter electromotive force occurring in the first load enters the second switching element when the power supply to the first load is interrupted, the surge absorbing element reduces the surge voltage applied to the second switching element, thus The switching between the opening and closing of the second switching element is suppressed. Therefore, even when the second load is an LED illuminator having high responsiveness, the case where the LED illuminator is briefly lit when the power supply to the first load is interrupted is suppressed.
本實施例的負載控制系統包括了開關裝置1、連接至第一終端(負載終端95及96)的第一負載、及連接至第二終端(負載終端93及94)的第二負載。第一負載為電感性負載(風扇負載400)，且第二負載為LED照明器(照明負載300)。突波吸收元件(突波吸收電路60)係用以降低當第一開關元件(接點111)被關閉時於該電感性負載中所發生的反電動勢施加至第二開關元件(雙向閘流體12)的突波電壓。The load control system of the present embodiment includes a switching device 1, a first load connected to the first terminals (load terminals 95 and 96), and a second load connected to the second terminals (load terminals 93 and 94). The first load is an inductive load (fan load 400) and the second load is an LED illuminator (lighting load 300). The surge absorbing element (surge absorbing circuit 60) is for reducing the application of a counter electromotive force occurring in the inductive load to the second switching element when the first switching element (contact 111) is turned off (bidirectional thyristor 12) The surge voltage.
因此，突波吸收元件降低了當第一開關元件被關閉時於該電感性負載中所發生的反電動勢施加至第二開關元件的突波電壓。所以，反電動勢所導致之在第二開關元件的開啟與關閉之間的切換被抑制。因此，即使當具有高回應性的LED照明器連接至第二終端時，第一開關元件被關閉時LED照明器被短暫地點亮之情況仍被抑制。Therefore, the surge absorbing element reduces the surge voltage applied to the second switching element by the counter electromotive force occurring in the inductive load when the first switching element is turned off. Therefore, the switching between the opening and closing of the second switching element caused by the counter electromotive force is suppressed. Therefore, even when the LED illuminator having high responsiveness is connected to the second terminal, the case where the LED illuminator is briefly lit when the first switching element is turned off is suppressed.
在上述之本實施例的開關裝置1中，從人類感測器70對於有人之偵測結果停止的時間起經過了該操作保持期間之後，信號處理單元40停止照明負載300及風扇負載400。然而，操作保持期間可為可調整的。例如，開關裝置1可包括一設定開關(例如，撥動式開關或旋轉式開關)，且可用該設定開關將操作保持期間設定在想要的期間。信號處理單元40可於來自人類感測器70之偵測信號的輸入停止(亦即，人類感測器70對於有人之偵測結果停止)之後立即關閉照明負載300並停止風扇負載400。In the above-described switching device 1 of the present embodiment, the signal processing unit 40 stops the illumination load 300 and the fan load 400 after the operation holding period has elapsed from the time when the human sensor 70 stops the detection result of the human. However, the operation hold period can be adjustable. For example, the switching device 1 may include a setting switch (for example, a toggle switch or a rotary switch), and the setting period may be used to set the operation holding period to a desired period. The signal processing unit 40 may turn off the lighting load 300 and stop the fan load 400 immediately after the input of the detection signal from the human sensor 70 is stopped (ie, the human sensor 70 stops the detection of a human).
在上述之本發明的開關裝置1中，繼電器10及11係非閂鎖繼電器。然而，繼電器10及11可為閂鎖繼電器。當繼電器10及11為閂鎖繼電器時，繼電器10及11其中每一者包括了一動作線圈(set coil)、及一復歸線圈(reset coil)。當電流流過動作線圈時，接點被開啟，且即使當被運載至設定線圈的電流停止時，該接點的開啟狀態仍然保持。當電流流過復歸線圈時，接點被關閉，且即使當被運載至復歸線圈的電流停止時，該接點的關閉狀態仍然保持。In the above-described switching device 1 of the present invention, the relays 10 and 11 are non-latch relays. However, relays 10 and 11 can be latched relays. When the relays 10 and 11 are latching relays, each of the relays 10 and 11 includes a set coil and a reset coil. When a current flows through the action coil, the contact is turned on, and even when the current carried to the set coil is stopped, the open state of the contact remains. When current flows through the return coil, the contact is closed, and even when the current carried to the return coil stops, the closed state of the contact remains.
在本實施例之開關裝置1中，使用照明負載300及風扇負載400做為負載。然而，開關裝置1的負載不限於照明負載300及風扇負載400、且可為其它電氣設備。In the switching device 1 of the present embodiment, the lighting load 300 and the fan load 400 are used as loads. However, the load of the switching device 1 is not limited to the lighting load 300 and the fan load 400, and may be other electrical devices.
本實施例之開關裝置1根據從人類感測器70輸入之偵測信號(做為觸發方式)而控制負載的操作。然而，用以改變負載之操作狀態的觸發方式不限於人類感測器70對於人的偵測結果。開關裝置1可使用人員對操作單元所進行之操作、或從遠端控制傳輸器傳輸之無線電信號的接收單元所進行之接收做為觸發方式而改變負載之操作狀態。The switching device 1 of the present embodiment controls the operation of the load based on the detection signal input from the human sensor 70 (as a triggering mode). However, the triggering method for changing the operational state of the load is not limited to the detection result of the human sensor 70 for a person. The switching device 1 can change the operational state of the load by using the operation performed by the operation unit or the receiving unit of the radio signal transmitted from the remote control transmitter as a trigger mode.
雖然已參照特定較佳實施例來描述本發明，但熟悉本技藝者可做出許多修改及變化而不超出本發明的真正精神及範圍(亦即申請專利範圍)。Although the present invention has been described with reference to the preferred embodiments thereof, many modifications and variations can be made without departing from the true spirit and scope of the invention.
