Description
本創作是關於一種感應式照明系統之切換控制方法。 This creation is about a switching control method for an inductive lighting system.
在現今環保意識高漲時代，能源之開發及消耗已被更加重視。針對能源消耗方面，又以節約用電是主要考量，蓋傳統電能生產過程會消耗大量環境資源，而電能之使用，則會造成環境負擔。此外，各國政府為增進社會公益，多採取調漲電價措施，以增加國家財政，亦間接促使用電人自主性管理用電量，達到環保節能之效果。故用電量如可有效控制，使電能之消耗達到最大效率，避免不必要浪費，除可使產業經濟效益增加，對商家之成本管理亦具有相當幫助。 In today's era of high environmental awareness, energy development and consumption have been paid more attention. In terms of energy consumption, the main consideration is to save electricity. The traditional electric energy production process consumes a lot of environmental resources, and the use of electric energy will cause an environmental burden. In addition, in order to promote social welfare, governments of various countries have adopted measures to increase electricity prices to increase national finances, and indirectly promote the use of electricity to manage power consumption independently, and achieve environmental protection and energy conservation. Therefore, the power consumption can be effectively controlled, so that the consumption of electric energy can be maximized, and unnecessary waste can be avoided. In addition to increasing the economic efficiency of the industry, the cost management of the merchant is also quite helpful.
為延長人類活動時間及增加工作環境，照明設備為日常中不可獲缺之物，目前常用照明以燈泡或燈管為主要光源，惟該些裝置即使經多次改良仍有其缺點，其中燈泡以鎢絲發光，光電轉換效率低，多數能量更消耗在熱能，故耗電量高，反應慢或容易損壞，而燈管中為使電子相互撞擊產生光，需要填充汞氣體，惟汞對環境所造成汙染係無可避免，不適於環保應用。取代傳統燈泡或燈管之主流技術，以發光二極體(Light-Emitting Diode：LED)呼聲最高，其利用電子在半導體材料能階中移動產生光的特性，具有耗電量低且效率高，又不似傳統燈泡以燈絲發光，因此使用壽命 長且不易損壞，或填充汞氣體對環境造成重大汙染，廣泛使用發光二極體取代傳統燈具係指日可待。 In order to prolong the activity time of human activities and increase the working environment, lighting equipment is an indispensable thing in daily life. Currently, lighting is mainly used as a light source or a light bulb. However, even if these devices have been improved many times, there are still some shortcomings. Tungsten wire emits light, the photoelectric conversion efficiency is low, and most of the energy is consumed in heat energy. Therefore, the power consumption is high, the reaction is slow or easy to be damaged, and in the lamp tube, in order to cause electrons to collide with each other to generate light, it is necessary to fill the mercury gas, but the mercury is applied to the environment. The pollution is inevitable and is not suitable for environmental protection applications. Replacing the mainstream technology of traditional light bulbs or lamps, Light-Emitting Diode (LED) has the highest voice, and it uses electrons to move light in the energy level of semiconductor materials to produce light. It has low power consumption and high efficiency. It’s not like a traditional light bulb that glows with a filament, so it’s long Long and not easily damaged, or filled with mercury gas causes significant pollution to the environment, and the widespread use of light-emitting diodes to replace traditional lamps is just around the corner.
照明裝置固然提升人類生活時間，惟能源之消耗也相對提高，為避免不必要浪費，一般照明裝置係利用自動化設計，當區域內無人時，燈具呈現關閉狀態，當有人靠近時，始將燈源開啟，如此則毋庸將照明裝置維持開啟狀態，消耗太多電源。上述自動化技術，大多以紅外線感應器(passive infrared sensor,PIR)完成，在有人接近或經過時，可以感測人體產生紅外線，進而產生一訊號予後端裝置。 Lighting equipment certainly enhances human life, but the energy consumption is relatively increased. In order to avoid unnecessary waste, the general lighting system utilizes automatic design. When there is no one in the area, the lamps are turned off. When someone approaches, the light source is turned on. Turn on, so there is no need to keep the lighting device on and consume too much power. Most of the above-mentioned automation technologies are completed by a passive infrared sensor (PIR), which can sense the human body to generate infrared rays when a person approaches or passes, and then generates a signal to the back end device.
習知技術中，提供一種燈具，設置一發光燈條，發光燈條包括複數個發光二極體，此燈具包括：一驅動模組、一殼體、一燈罩及燈座。驅動模組包括一驅動單元及一規格辨識單元，驅動單元對應規格辨識單元獲得的一規格資料提供特定電子特性的電子環境予發光燈條，使得發光燈條發光。發光燈條是設置於殼體及燈罩之間，並經由燈座電性連接驅動模組，其中，前述規格資料係由規格辨識單元自發光燈條所獲得。藉由設置於燈具中的規格辨識單元，取得儲存於發光燈條的規格儲存單元中的一規格資料，以辨識出發光燈條及/或其內的發光元件的電子特性，從而提供符合發光燈條所用的電子特性的電子環境，使得發光燈條發光。惟此種方法倚靠規格辨識單元辨識不同規格之燈具，需另外設置規格儲存單元，造成額外的耗電量或燈具空間。 In the prior art, a lamp is provided, and a light bar is disposed. The light bar includes a plurality of light emitting diodes, and the lamp comprises: a driving module, a casing, a lamp cover and a lamp holder. The driving module includes a driving unit and a specification identifying unit. The driving unit provides an electronic environment with specific electronic characteristics to the light bar corresponding to a specification data obtained by the specification identifying unit, so that the light bar emits light. The light bar is disposed between the casing and the lamp cover, and is electrically connected to the driving module via the lamp socket. The specification data is obtained by the specification identifying unit from the light bar. Obtaining a specification data stored in the specification storage unit of the light bar by the specification identification unit disposed in the lamp to identify the electronic characteristics of the light bar and/or the light element therein, thereby providing the illumination lamp The electronic environment of the electronic characteristics used in the strip causes the light strip to illuminate. However, this method relies on the specification identification unit to identify lamps of different specifications, and an additional specification storage unit is required, resulting in additional power consumption or lamp space.
另一習知技術係一種發光二極體控制電路，適用於控制一發光二極體燈管，該發光二極體燈管包含複數發光二極體燈串，其中該發光二極體燈管較佳的最大輸入電壓不超過70伏特且發光二極體 燈串的燈串數目較佳限制於4串以內。該發光二極體控制電路包含複數二極體、一保護電路、複數定電流電路及一切換開關。每一二極體的正極連接單一發光二極體燈串的輸出端。保護電路連接於每一二極體的負極，當該發光二極體燈管的輸入端電壓高於一臨界值或是該發光二極體燈管中有發光二極體出現短路時，該保護電路輸出一切換信號。每一定電流電路連接單一發光二極體燈串的輸出端，並依據一開關控制信號控制該定電流電路是否工作以進而控制該發光二極體燈管是否工作，且依據一調光控制信號控制該發光二極體燈管的亮度。切換開關在未接收到該切換信號時不影響該開關控制信號，並在接收到該切換信號時通過該開關控制信號控制該發光二極體燈管不工作。上述方法利用定電流電路，使每個發光二極體燈串都可以工作，並控制亮度，惟該方法為避免電壓過大損毀，其限制燈串最大電壓為不超過70伏特，如此一來，若使用者需要更多的燈串，使用超過70伏特，此方法即不可行。 Another conventional technology is a light-emitting diode control circuit, which is suitable for controlling a light-emitting diode lamp. The light-emitting diode lamp comprises a plurality of light-emitting diode lamp strings, wherein the light-emitting diode lamp is compared. Good maximum input voltage does not exceed 70 volts and LED The number of strings of the string is preferably limited to 4 strings. The LED control circuit includes a plurality of diodes, a protection circuit, a plurality of constant current circuits, and a switch. The anode of each diode is connected to the output of a single light-emitting diode string. The protection circuit is connected to the negative pole of each diode, and the protection is when the voltage of the input terminal of the light-emitting diode tube is higher than a critical value or the light-emitting diode of the light-emitting diode tube is short-circuited. The circuit outputs a switching signal. Each constant current circuit is connected to an output end of the single light emitting diode string, and controls whether the constant current circuit works according to a switch control signal to thereby control whether the light emitting diode lamp operates, and is controlled according to a dimming control signal The brightness of the light-emitting diode tube. The switch does not affect the switch control signal when the switch signal is not received, and controls the light-emitting diode lamp to be inoperative by the switch control signal when receiving the switch signal. The above method utilizes a constant current circuit to enable each of the LED strings to operate and control the brightness, but the method is to prevent the voltage from being excessively damaged, and the maximum voltage of the lamp string is not more than 70 volts, so that Users need more strings and use more than 70 volts. This method is not feasible.
前述技術，對於發光二極體燈具之驅動，並無法確定燈具之工作電壓，導致每次感應器產生有人接近的訊號後，電源需從0伏特提升至燈具之工作電壓，又當人離開後，電源又需從燈具之工作電壓降至0伏特，如此燈具在工作與非工作切換之電壓範圍過大，導致切換時間過長。因此，有必要將感應器產生工作訊號時，縮短燈具切換之時間。 The foregoing technology, for the driving of the light-emitting diode lamp, cannot determine the working voltage of the lamp, so that after each sensor generates a signal that is approached by the sensor, the power source needs to be raised from 0 volts to the working voltage of the lamp, and when the person leaves, The power supply needs to be reduced from the operating voltage of the luminaire to 0 volts, so that the voltage range of the luminaire in the working and non-working switching is too large, resulting in too long switching time. Therefore, it is necessary to shorten the time when the lamp is switched when the sensor generates a working signal.
本創作之主要目的在於提供一種照明系統，在感應訊號產生時，可迅速切換燈具工作狀態。 The main purpose of this creation is to provide a lighting system that can quickly switch the working state of the luminaire when the sensing signal is generated.

When the signal generation must work, the voltage supplied to the luminaire is slightly larger than the over-operating voltage, and when the signal is not in operation, the supply is made. The voltage of the luminaire is slightly less than the operating voltage.
為達到上述所指稱之各目的與功效，本創作係揭露一種照明系統，具有一感應電路、一控制器及至少一燈具，為了增加燈具切換工作狀態之速度，本創作之控制器可以偵測該些該些燈具之總電流，找出燈具之工作電壓。該控制器更包含一偵測單元，用以偵測該些燈具之工作電流，控制器可提供一電壓，該電壓係逐漸地增幅，並自動偵測該些燈具每次電壓增幅後之總電流，利用每次增幅電壓與每次偵測之總電流計算目前該些燈具之發光二極體全部導通之工作電壓，確定該工作電壓後，該控制器即停止對驅動電壓增幅，使後端發光二極體不致應驅動電壓過大而損毀，此外，當需要該些燈具在非工作狀態時，控制器將供給燈具之電壓降至略低於工作電壓，使該些發光二極體全部非導通。 In order to achieve the above-mentioned various purposes and effects, the present invention discloses a lighting system having a sensing circuit, a controller and at least one luminaire. In order to increase the speed at which the luminaire is switched, the controller of the present invention can detect the The total current of the lamps is used to find the working voltage of the lamps.

After determining the working voltage, the controller stops increasing the driving voltage, so that the back end emits light. The diode does not damage the driving voltage too much. In addition, when the lamps are required to be in an inoperative state, the controller reduces the voltage supplied to the lamp to be slightly lower than the operating voltage, so that the light-emitting diodes are all non-conductive.

為使 貴審查委員對本創作之特徵及所達成之功效有更進一步之瞭解與認識，謹佐以較佳之實施例及配合詳細之說明，說明如後：參照第一圖，其係為本創作一較佳實施例之照明系統示意圖；如圖所示，本創作之照明系統其係包含：一感應電路100、一控制器200、以及至少一個燈具300。控制器200耦接感應電路100，燈具300耦接控制器200。感應電路100係產生一工作訊號予控制器200，該控制器200依據工作訊號，切換燈具300之工作狀態。其中感應電路100係PIR控制，燈具300係以複數個發光二極體組裝，且燈具300型式可以係燈泡型或燈管型。此外，控制器200可偵測燈具300之總電流，依據總電流決定燈具300之工作電壓，並調整供給燈具300之電壓，使該電壓切換在略高或略低於工作電壓。 In order to give your reviewers a better understanding and understanding of the characteristics of the creation and the efficacies achieved, please refer to the preferred embodiment and the detailed explanations as explained below: with reference to the first figure, it is a creation A schematic diagram of a lighting system of a preferred embodiment; as shown, the lighting system of the present invention comprises: a sensing circuit 100, a controller 200, and at least one luminaire 300. The controller 200 is coupled to the sensing circuit 100 , and the luminaire 300 is coupled to the controller 200 . The sensing circuit 100 generates a working signal to the controller 200, and the controller 200 switches the working state of the lamp 300 according to the working signal. The sensing circuit 100 is controlled by PIR, and the lamp 300 is assembled by a plurality of light emitting diodes, and the type of the lamp 300 can be a bulb type or a lamp type. In addition, the controller 200 can detect the total current of the luminaire 300, determine the operating voltage of the luminaire 300 according to the total current, and adjust the voltage supplied to the luminaire 300 to switch the voltage slightly higher or slightly lower than the operating voltage.
請參照第二圖，其係為本創作控制器之較佳實施例示意圖；如圖所示，本創作之控制器200，其係控制單元201，控制單元201具有，一輸入端Vi耦接電源，及輸出端Vo輸出一工作電壓供給至少一個燈具300，以及一偵測單元202偵測該燈具之一總電流，並將該總電流數據予控制單元201，控制單元201依據總電流調整工作電壓。此外，控制單元201利用偵測單元202偵測之總電流取得該些發光二極體全部導通之工作電壓。藉由上述技術，透過本創作之控制器200，即使輸出端發光二極體串聯或並聯數量未知時，該控制器200仍可取得燈具內部全部發光二極體導通之工作電壓，如此一來，當燈具300在非工作狀態時，控制器200可將供給燈具300之電壓降至略低於工作電壓，當感應電路100感應並傳送工作訊號時，控制器200僅需略增微小電壓，即可使燈具300迅速切換至工作狀態，縮短了切換所需之時間。 Please refer to the second figure, which is a schematic diagram of a preferred embodiment of the authoring controller. As shown in the figure, the controller 200 of the present invention is a control unit 201. The control unit 201 has an input terminal Vi coupled to the power supply. And the output terminal Vo outputs an operating voltage to the at least one lamp 300, and a detecting unit 202 detects the total current of the lamp, and the total current data is sent to the control unit 201, and the control unit 201 adjusts the working voltage according to the total current. . In addition, the control unit 201 uses the total current detected by the detecting unit 202 to obtain the working voltages of all the LEDs that are turned on. Through the above technology, through the controller 200 of the present invention, even if the number of series or parallel connection of the output terminal diodes is unknown, the controller 200 can obtain the working voltage of all the LEDs in the lamp, so that When the luminaire 300 is in the non-operating state, the controller 200 can reduce the voltage supplied to the luminaire 300 to be slightly lower than the working voltage. When the sensing circuit 100 senses and transmits the working signal, the controller 200 only needs to slightly increase the small voltage. The luminaire 300 is quickly switched to the working state, shortening the time required for switching.
此外，本創作之另一實施例，可以將供給燈具300之明亮度視其所需而調整。由於控制器200可準確偵測燈具300內部全部發光二極體之工作電壓，且燈具300導通之工作電壓必定小於額定電壓，故供給燈具300之電壓在平時可調整至略高於工作電壓即可，使燈具處於微亮狀態，當感應電路100產生工作訊號時，則供給燈具300之電壓可增加至額定電壓，使燈具300亮度滿載，則平常時候燈具300亮度可能僅有10%，或者視其所需調整，當感應電路產生工作訊號時，燈具300亮度轉為100%。舉例而言，在有些場合中，例如停車場，平時燈具300明亮度僅10%，當有人接近時，則燈具300明亮度為100%，兼顧安全及省電之目的。 Moreover, in another embodiment of the present creation, the brightness of the supply luminaire 300 can be adjusted as needed. Since the controller 200 can accurately detect the working voltage of all the LEDs in the lamp 300, and the working voltage of the lamp 300 is necessarily lower than the rated voltage, the voltage supplied to the lamp 300 can be adjusted to be slightly higher than the working voltage. When the sensor circuit 100 generates a working signal, the voltage supplied to the lamp 300 can be increased to a rated voltage, so that the brightness of the lamp 300 is full, and the brightness of the lamp 300 may be only 10%, or The required adjustment, when the sensing circuit generates a working signal, the brightness of the luminaire 300 is turned to 100%. For example, in some occasions, such as parking lots, the brightness of the luminaire 300 is only 10%. When someone approaches, the luminaire 300 has a brightness of 100%, which is both safe and power-saving.
為說明本創作之工作原理，請參閱第三圖，其係為發光二極體之 特性曲線；如圖所示，本創作發光二極體控制器之控制單元，依據習知單一發光二極體操作時，順向偏壓時，如曲線C1所示，具有一切入電壓Vcut，供給電壓小於該切入電壓Vcut時，發光二極體係未導通狀態，工作電流非常微小，且趨近於0，但是當供給電壓大於切入電壓Vcut時，發光二極體係導通狀態，工作電流急速上升。同理可推，多數個相同發光二極體串聯，如曲線C2所示，當串聯數越多時，切入電壓Vcut則會越大；多數個相同發光二極體並聯，當並聯數越多，工作電流增加速度會越快，如曲線C3所示；若為相同發光二極體同時串聯及並聯時，則切入電壓Vcut增加，同時工作電流也一併增加。 To illustrate the working principle of this creation, please refer to the third figure, which is the characteristic curve of the light-emitting diode; as shown in the figure, the control unit of the creative light-emitting diode controller is based on the conventional single light-emitting diode. when operating, when forward biased, as shown in the curve C 1, having all the VCUT voltage, the supply voltage is less than the cut-VCUT voltage, the light emitting diode is not conducting state system, the operating current is very small, and is close to 0, However, when the supply voltage is greater than the cut-in voltage Vcut, the light-emitting diode system is turned on, and the operating current rises rapidly. Similarly, most of the same light-emitting diodes can be connected in series. As shown by the curve C 2 , when the number of series is larger, the cut-in voltage Vcut will be larger; most of the same light-emitting diodes are connected in parallel, and the more the number of parallel connections , the faster the speed of the operating current increases, as shown in the curve C 3; if the same series and in parallel to the light emitting diode while the cut Vcut voltage is increased while the operating current is also increased together.
請參照第四圖，其係為本創作一較佳實施例之控制器工作流程圖；如圖所示，依據前述發光二極體控制器200，其步驟說明如下，在步驟S10，控制單元201輸出端產生一電壓予至少一燈具；步驟S20，偵測單元202偵測該燈具之總電流；步驟S30，控制單元201增幅該電壓；步驟S40：偵測單元202偵測該燈具之總電流；步驟S50：控制單元201計算電壓與總電流之斜率；步驟S60：判斷該斜率是否為所欲之斜率，使得發光二極體皆導通；步驟S70：若該些發光二極體皆為全部導通，即產生一導通訊號，使控制單元201不再繼續對電壓增幅，若該些發光二極體非全部導通，即回到步驟S30。透過上述方法流程，可取得該些發光二極體完全導通之一工作電壓，並且利用控制器200將電壓維持在略高於工作電壓，使該些發光二極體不致因電壓過大而毀損。 Please refer to the fourth figure, which is a working flow chart of the controller according to a preferred embodiment of the present invention; as shown in the figure, according to the foregoing LED controller 200, the steps are as follows. In step S10, the control unit 201 The output end generates a voltage to the at least one luminaire; in step S20, the detecting unit 202 detects the total current of the luminaire; in step S30, the control unit 201 amplifies the voltage; and step S40: the detecting unit 202 detects the total current of the luminaire; Step S50: the control unit 201 calculates the slope of the voltage and the total current; step S60: determining whether the slope is the desired slope, so that the light-emitting diodes are all turned on; step S70: if the light-emitting diodes are all turned on, That is, a pilot communication number is generated, so that the control unit 201 does not continue to increase the voltage. If the light-emitting diodes are not all turned on, the process returns to step S30. Through the above method, one of the operating voltages of the light-emitting diodes can be completely turned on, and the controller 200 can maintain the voltage slightly higher than the operating voltage, so that the light-emitting diodes are not damaged due to excessive voltage.
請參照第五圖，其係為本創作另一較佳實施例之控制器示意圖；如圖所示，本創作之控制器200，其中該控制單元201更包含：運 算電路2011及驅動電路2012。運算電路2011具有兩輸入端，其中一端接收供應燈具300之電壓，另一端接收由偵測單元202得到之總電流訊號，該驅動電路2012具有一輸入端耦接電源，輸出端輸出供應燈具300之電壓，驅動電路2012逐漸地增幅供應給燈具之電壓，使電壓由初始值每次時間區間增加一微小伏特，該微小伏特值可視使用者所需調整，例如可調整範圍從10-5mV到10-1mV，當解析度需求越大時，則電壓每次增加幅度越小。運算電路2011之一輸入端接收供給發光二極體之電壓時，另一輸入端即可得到一總電流，當電壓每次增加一微小伏特，就得到另一總電流，此時，運算電路2011依據增幅前之電壓及總電流與增幅後之電壓與總電流，計算電壓與電流斜率，透過該斜率即可判斷目前所使用燈具所有發光二極體導通之工作電壓，當運算電路2011得到發光二極體D之工作電壓，即將一工作訊號傳送予驅動電路2012，驅動電路2012接收工作訊號時，即停止繼續增幅，使供給之電壓不再繼續增加，此時電壓等於工作電壓。藉由上述裝置及方法，電源供應器透過本創作之發光二極體之控制器200，當輸出端耦接相同發光二極體數量未知時，可得到目前需要工作電壓。 Please refer to the fifth figure, which is a schematic diagram of a controller according to another preferred embodiment of the present invention. As shown in the figure, the controller 200 of the present invention further includes: an arithmetic circuit 2011 and a driving circuit 2012. The operation circuit 2011 has two input terminals, one end of which receives the voltage of the supply lamp 300, and the other end receives the total current signal obtained by the detection unit 202. The drive circuit 2012 has an input terminal coupled to the power source, and the output terminal outputs the supply lamp 300. The voltage, the driving circuit 2012 gradually increases the voltage supplied to the lamp, so that the voltage is increased by one microvolt per time interval from the initial value, and the microvolt value can be adjusted according to the user's needs, for example, the adjustable range is from 10 -5 mV to 10 -1 mV, when the resolution demand is larger, the voltage is increased every time. When one input terminal of the operation circuit 2011 receives the voltage supplied to the light-emitting diode, the other input terminal can obtain a total current. When the voltage is increased by one microvolt each time, another total current is obtained. At this time, the operation circuit 2011 Calculate the voltage and current slope according to the voltage and total current before the amplification and the voltage and total current after the amplification. Through the slope, the working voltage of all the LEDs of the currently used lamps can be judged, and the operation circuit 2011 is illuminated. The working voltage of the body D is to transmit a working signal to the driving circuit 2012. When the driving circuit 2012 receives the working signal, the driving circuit 2012 stops continuing to increase the amplitude, so that the voltage of the supply does not continue to increase, and the voltage is equal to the working voltage. With the above device and method, the power supply device passes through the controller 200 of the present invention, and when the number of the same light-emitting diodes coupled to the output terminal is unknown, the current required operating voltage can be obtained.
請參照第六圖，其係為本創作運算電路之計算斜率示意圖；如圖所示，該圖係局部放大發光二極體特性曲線C，其中驅動電路每次供給之電壓為Vn、Vn1、Vn2及Vn3，電壓Vn及Vn1小於Vcut，電壓Vn2及Vn3大於Vcut。當電壓為Vn時具有一總電流In，當電壓增幅至Vn1時，具有另一總電流In1，此時，運算電路2011由電壓Vn及總電流In，與電壓Vn1及總電流In1，可得一斜率S1，計算公式為：
本創作之照明系統，係包含一感應電路、一控制器、至少一個燈具，感應電路係當有人靠近時，可產生一工作訊號。控制器耦接 感應電路，接收感應電路之工作訊號，燈具耦接控制器，該控制器可偵測燈具之總電流，依據該總電流，偵測燈具之工作電壓。當無人接近照明系統時，控制器將供給燈具之電壓維持在略低於工作電壓，使燈具之發光二極體處於未導通狀態，當感應電路偵測到有人靠近時，控制器供給燈具之電壓略增一微小伏特，該電壓超過燈具之工作電壓，使燈具之發光二極體處於導通狀態，如此可縮短該燈具切換所需時間。 The lighting system of the present invention comprises a sensing circuit, a controller and at least one luminaire, and the sensing circuit generates a working signal when someone approaches. Controller coupling The sensing circuit receives the working signal of the sensing circuit, and the lamp is coupled to the controller. The controller can detect the total current of the lamp, and detect the working voltage of the lamp according to the total current. When no one approaches the lighting system, the controller maintains the voltage supplied to the lamp slightly below the operating voltage, so that the light-emitting diode of the lamp is in a non-conducting state, and when the sensing circuit detects that someone is approaching, the controller supplies the voltage of the lamp. A slight increase of one microvolt, the voltage exceeds the working voltage of the lamp, so that the light-emitting diode of the lamp is in a conducting state, which can shorten the time required for the lamp to switch.
