LED方向燈之動態負載模組Dynamic load module for LED directional lights

本創作為一種使用在LED方向燈之動態負載模組,旨在克服車輛方向燈使用LED做為發光元件而造成異常作動的情形,使LED方向燈能夠符合實際需要。The present invention is a dynamic load module used in an LED directional light, which aims to overcome the situation in which the vehicle direction light uses the LED as a light-emitting element to cause an abnormal operation, so that the LED directional light can meet the actual needs.

按,車輛之方向燈攸關於其他用路人辨識行駛車輛之動向,而為了確保車輛方向燈必須運作正常,法規規定車輛上的左、右側方向燈其中之一若無法正常運作時,其他方向燈必須以加快閃爍,藉以警示使用者有方向燈故障必須維修。According to the direction of the vehicle, the direction of the other vehicles is recognized by the passerby. In order to ensure that the direction lights of the vehicle must be in normal operation, if the regulations stipulate that one of the left and right direction lights on the vehicle cannot operate normally, the other direction lights must In order to speed up the flashing, it is necessary to warn the user that the direction light failure must be repaired.

上述方向燈其中之一損壞而其他方向燈必須以快閃方式運作的模式,對於傳統使用鎢絲燈泡作為方向燈的電路而言並不困難,原因是鎢絲燈泡的耗電量高,其負載約12W,屬高耗電量而且容易燒掉,當其中之一損壞時,控制電路可以很容易地偵測出負載變化,進而令其他方向燈快閃。One of the above-mentioned directional lamps is damaged and the other directional lamps must be operated in a flash mode. It is not difficult for the conventional tungsten filament bulb to be used as a directional lamp because the power consumption of the tungsten filament bulb is high and its load is high. About 12W, it is high power consumption and easy to burn. When one of them is damaged, the control circuit can easily detect the load change, and then the other direction lights flash quickly.

然而近年來,由於LED具有低耗電量、使用壽命長的優點,可以解決傳統方向燈使用鎢絲燈泡容易燒掉的問題,也可以減少耗電量,因此將LED使用在車輛燈具上已是必然趨勢;當使用LED作為方向燈的發光 元件時,由於每一LED方向燈組的耗電量僅約2W,雖然在使用上具有低耗電量及使用壽命長的優勢,但卻也造成了前述控制電路偵測負載變化的障礙。However, in recent years, LEDs have the advantages of low power consumption and long service life, which can solve the problem that the conventional directional lamp is easy to burn using the tungsten light bulb, and can also reduce the power consumption. Therefore, the use of the LED on the vehicle luminaire is already Inevitable trend; when using LED as a directional light In the case of components, since the power consumption of each LED direction lamp group is only about 2W, although it has the advantages of low power consumption and long service life in use, it also causes the above control circuit to detect the load change obstacle.

例如:當LED方向燈組的其中之一故障時,該損壞LED方向燈組所減少的負載相較於輛車上的總負載比例相當低,使控制電路很難偵測到細微的負載變化,亦無法驅動其他方向燈快閃,如此一來,就造成使用上無法警示的狀態,亦無法符合法令規範。For example, when one of the LED directional lamp groups fails, the load reduced by the damaging LED directional lamp group is relatively low compared to the total load on the vehicle, making it difficult for the control circuit to detect subtle load changes. It is also impossible to drive other direction lights to flash quickly. As a result, it is in a state where it cannot be used for warning, and it cannot comply with the laws and regulations.

如第一圖所示,在已知的技術中,為了解決上述偵測負載困難的問題,遂有業者在閃光器1上電連接一組偵測電路2,該偵測電路2提供一額外的電力繞過閃光器1內的ON/OFF閃爍開關,並且直接電連接於LED方向燈組3的電源輸入端。當車輛開啟方向燈開關時,控制電路(圖略)會先通過偵測電路2輸入電源傳輸到LED方向燈組3的電源輸入端;此時,若該LED方向燈組3處於損壞的狀態,因偵測電路2無負載的信號回授,因此方向燈控制電路就可以讓其他正常的LED方向燈組3快閃,以達成前述之目的。As shown in the first figure, in the known technology, in order to solve the above problem of detecting load difficulty, a manufacturer is electrically connected to a set of detecting circuits 2 on the flasher 1, and the detecting circuit 2 provides an additional The power bypasses the ON/OFF flashing switch in the flasher 1 and is directly electrically connected to the power input of the LED directional light group 3. When the vehicle turns on the directional light switch, the control circuit (not shown) is first transmitted through the detection circuit 2 to the power input end of the LED directional light group 3; at this time, if the LED directional light group 3 is in a damaged state, Because the detection circuit 2 has no load feedback signal, the directional light control circuit can flash other normal LED directional light groups 3 to achieve the foregoing purpose.

上述利用偵測電路來偵測LED方向燈組運作是否正常的方式,在理想狀態下,若LED方向燈組已處於損壞狀態,固然能夠偵測到迴路斷開的損壞狀態,進而發揮其應有之功能。然而,根據本案創作人的實際測試,發現若LED方向燈組實際上是屬於正常狀態時,該偵測電路的使用反而會讓其他正常的LED方向燈組產生異常動作。In the above, the detection circuit is used to detect whether the operation of the LED direction lamp group is normal. In an ideal state, if the LED direction lamp group is in a damaged state, the damage state of the circuit disconnection can be detected, and then the proper function can be utilized. The function. However, according to the actual test of the creator of the case, it is found that if the LED directional light group is actually in a normal state, the use of the detection circuit will cause other normal LED directional light groups to generate abnormal actions.

上述偵測電路造成LED方向燈組異常動作的情形有兩種,其中之一是當偵測電路2傳輸偵測電源到LED方向燈組3的電壓過低時,方 向燈控制電路可能會無法偵測到LED方向燈組3之負載,進而誤判所有方向燈都損壞,使全部的方向燈都不作動;特別是因為車輛使用環境致使其本身的電壓就不夠穩定,造成這種情形經常發生。There are two kinds of situations in which the detection circuit causes the LED direction group to operate abnormally, one of which is when the detection circuit 2 transmits the detection power to the LED direction group 3, the voltage is too low. The light control circuit may not be able to detect the load of the LED directional light group 3, and thus misjudge all the directional lights to be damaged, so that all the directional lights are not activated; in particular, the voltage of the vehicle itself is not stable enough due to the environment of the vehicle. This situation often occurs.

另一種異常動作的情形是偵測電路2傳輸電源到LED方向燈組3的電壓較高時,此電力的提供固然比較容易偵測到LED方向燈組3的負載以及方向燈迴路是否正常,然而也會造成該LED方向燈組3微亮;此時,當後續控制電路正常提供電源讓LED方向燈組3作動閃爍時,原本LED方向燈組3交替點亮/熄滅的閃爍動作,在應該熄滅時,就會因為偵測電路所提供多餘的電力而造成LED方向燈組3恆常微亮,這種情形無疑地會降低閃爍辨識度,亦屬於方向燈異常動作的一種。Another case of abnormal operation is that when the detection circuit 2 transmits the power to the LED directional lamp group 3, the supply of the power is relatively easy to detect whether the load of the LED directional lamp group 3 and the directional lamp circuit are normal. It also causes the LED direction light group 3 to be slightly bright; at this time, when the subsequent control circuit normally supplies power to cause the LED direction light group 3 to be activated to flash, the original LED direction light group 3 alternately lights up/extinguished, and should be extinguished. At this time, the LED directional light group 3 is always brightly lit due to the excess power provided by the detecting circuit. This situation will undoubtedly reduce the flicker recognition degree, and is also a kind of abnormal action of the directional light.

有鑑於上述問題,本創作人乃據其多年從事相關領域的設計經驗,特別是致力車輛LED燈具控制之實務經驗,創作出LED方向燈之動態負載模組,不但能有效地讓偵測電路能正常行使偵測功能,並且讓LED方向燈組可以正常運作。In view of the above problems, the creator has created a dynamic load module for LED directional lights based on his years of experience in related fields, especially the practical experience of LED lighting control, which not only enables the detection circuit to effectively The detection function is normally performed and the LED directional light group can operate normally.

本創作之目的在於提供一種使用在LED方向燈上的動態負載模組,旨在克服車輛方向燈使用LED做為發光元件而造成異常作動的情形,使LED方向燈能夠符合實際需要。The purpose of the present invention is to provide a dynamic load module for use in an LED directional light, which aims to overcome the situation in which the vehicle direction light uses the LED as a light-emitting element to cause an abnormal operation, so that the LED directional light can meet the actual needs.

為達成上述目的,本創作LED方向燈之動態負載模組係電連接於閃光器的電源輸出端與LED方向燈組的電源輸入端之間,包括有一負載電路,以及一能控制負載電路斷開之保護電路;當閃光器啟動初始, 其偵測電路通過電源輸出端輸出偵測信號以偵測LED方向燈組是否運作正常時,負載電路可以消耗掉偵測信號多餘之電力以避免LED方向燈組微亮,之後通過保護電路來控制負載電路斷開後,即可使偵測電路能夠正常行使偵測功能,並且讓正常的LED方向燈組運作時不會持續微亮。In order to achieve the above objective, the dynamic load module of the LED direction light is electrically connected between the power output end of the flasher and the power input end of the LED direction light group, and includes a load circuit, and a control load circuit disconnection Protection circuit; when the flasher starts, When the detection circuit outputs a detection signal through the power output terminal to detect whether the LED direction light group is working normally, the load circuit can consume the excess power of the detection signal to avoid the LED direction light group being slightly bright, and then controlled by the protection circuit. After the load circuit is disconnected, the detection circuit can normally perform the detection function, and the normal LED direction light group does not continuously light up when it operates.

上述設計之原理,是當LED方向燈組處於正常狀態時,負載電路可以消耗掉偵測信號多餘之電力,使LED方向燈組不會產生微亮,之後通過保護電路來控制負載電路斷開後,方向燈控制電路即可以正常供電,使該LED方向燈組正常閃爍運作時不會持續微亮。The principle of the above design is that when the LED directional lamp group is in a normal state, the load circuit can consume the excess power of the detection signal, so that the LED directional lamp group does not generate a slight light, and then the protection circuit is used to control the load circuit after disconnection. The directional light control circuit can supply power normally, so that the LED directional light group does not continuously light up when it is normally blinking.

而當該LED方向燈組處於損壞狀態時,LED方向燈組的電源輸入端處於迴路斷開狀態,負載電路雖然一開始消耗掉偵測信號之電力,但是當保護電路控制負載電路斷開後,偵測電路即能夠正常偵測到LED方向燈組無負載而處於損壞狀態,進而令其他方向燈快閃。When the LED directional light group is in a damaged state, the power input end of the LED directional light group is in a loop disconnection state, and although the load circuit initially consumes the power of the detection signal, when the protection circuit controls the load circuit to be disconnected, The detection circuit can normally detect that the LED direction light group is in a damaged state without load, and then the other direction lights flash quickly.

換言之,藉由本創作LED方向燈之動態負載模組,不但可以使偵測電路能夠正常偵測到LED方向燈組處於損壞狀態,若LED方向燈組為正常時,亦可以避免LED方向燈組產生異常微亮的問題。In other words, the dynamic load module of the LED direction light can not only enable the detection circuit to detect that the LED direction light group is in a damaged state, but also avoid the LED direction light group if the LED direction light group is normal. An unusually bright problem.

此外,前述能夠控制負載電路斷開之保護電路,實施時可以為一時序控制迴路,以一設定時間讓負載電路斷開。或者,保護電路亦可以為一能偵測負載電路之電壓的電壓偵測迴路,當電壓偵測迴路偵測到負載電路消耗偵測信號多餘之電力後,即可令負載電路斷開。In addition, the foregoing protection circuit capable of controlling the disconnection of the load circuit may be implemented as a timing control loop to disconnect the load circuit for a set time. Alternatively, the protection circuit can also be a voltage detection circuit capable of detecting the voltage of the load circuit. When the voltage detection circuit detects that the load circuit consumes excess power of the detection signal, the load circuit can be disconnected.

實施時,本創作動態負載模組與LED方向燈組之間可進一步設置一電源控制模組,該電源控制模組包括一連接於LED方向燈組之電源輸入端的電源控制單元、一連接於負載端的輸出功率適配單元,以及一 設置在電源控制單元與輸出功率適配單元之間的電源開關;其中,該電源控制單元包括一設定有最小啟動電壓值的啟動電壓偵測電路、以及一設定有最大啟動電壓值的過壓偵測電路,使電源供應端的輸入電壓小於所述最小啟動電壓值或大於最大啟動電壓值狀態下,該電源開關為不導通狀態而不供電至功率適配單元;而電源供應端的輸入電壓大於所述最小啟動電壓值並且小於所述最大啟動電壓值狀態下,令該電源開關為開通狀態,以通過輸出功率適配單元依負載需求供應電源至負載端,藉此以兼具防止高電壓突波通過而對負載造成損壞,以及防止低壓弱電致使迴路異常動作之功效。During implementation, a power control module may be further disposed between the dynamic load module and the LED directional light group, and the power control module includes a power control unit connected to the power input end of the LED directional light group, and a connection to the load End output power adaptation unit, and one a power switch disposed between the power control unit and the output power adapting unit; wherein the power control unit includes a starting voltage detecting circuit configured with a minimum starting voltage value, and an overvoltage detecting set with a maximum starting voltage value Measuring circuit, when the input voltage of the power supply terminal is less than the minimum starting voltage value or greater than the maximum starting voltage value, the power switch is in a non-conducting state and is not supplied to the power matching unit; and the input voltage of the power supply terminal is greater than the When the minimum starting voltage value is less than the maximum starting voltage value, the power switch is turned on to supply the power to the load end according to the load requirement by the output power matching unit, thereby preventing the high voltage surge from passing through Damage to the load and the effect of preventing low voltage weak currents from causing abnormal operation of the circuit.

又,為了不影響車輛原有的方向燈控制電路、閃光器以及偵測電路的運作,本創作之動態負載模組以及電源控制模組可共同安裝在LED方向燈組之電路板上,使本創作能易於實施。Moreover, in order not to affect the operation of the original directional light control circuit, the flasher and the detecting circuit of the vehicle, the dynamic load module and the power control module of the present invention can be jointly mounted on the circuit board of the LED directional light group, so that Creation can be easy to implement.

以下依據本創作之技術手段,列舉出適於本創作之實施方式,並配合圖式說明如後:如第二圖所示,本創作LED方向燈之動態負載模組係電連接於閃光器100的電源輸出端101與LED方向燈組200的電源輸入端201之間,其架構包括有一負載電路10,以及一能夠控制該負載電路10斷開之保護電路20。In the following, according to the technical means of the creation, the implementation method suitable for the creation is listed, and the description is as follows: as shown in the second figure, the dynamic load module of the LED direction light is electrically connected to the flasher 100. Between the power output 101 and the power input 201 of the LED directional light set 200, the architecture includes a load circuit 10, and a protection circuit 20 capable of controlling the load circuit 10 to be disconnected.

其中,所述閃光器100內建有偵測電路(未顯示)連接於電源輸出端101,當閃光器100啟動初始,該偵測電路先通過電源輸出端101輸出偵測信號以偵測LED方向燈組200是否運作正常時,負載電路10可以消耗掉該偵測信號多餘之電力,以避免LED方向燈組200微亮,之後通過保護電路20來控制負載電路10斷開後,即可使閃光器100的偵測電路能夠正常偵測LED方向燈組200是否正常,並且讓正常的LED方向燈組200閃爍運作時不會持續微亮。The flasher 100 has a detection circuit (not shown) connected to the power output terminal 101. When the flasher 100 is activated, the detection circuit first outputs a detection signal through the power output terminal 101 to detect the LED direction. When the lamp group 200 is operating normally, the load circuit 10 can consume excess power of the detection signal to prevent the LED direction light group 200 from being slightly bright, and then after the load circuit 10 is controlled to be disconnected by the protection circuit 20, the flash can be made. The detecting circuit of the device 100 can normally detect whether the LED directional light group 200 is normal, and does not continue to be slightly bright when the normal LED directional light group 200 is blinking.

如第三圖所示,上述本創作設計之原理,是當LED方向燈組200處於正常狀態時,負載電路10可以消耗掉偵測信號多餘之電力,使LED方向燈組200不會產生微亮,之後通過保護電路20來控制負載電路10斷開後,方向燈控制電路即可以正常供電,使該LED方向燈組200能夠正常閃爍。As shown in the third figure, the principle of the above-mentioned creative design is that when the LED directional light group 200 is in a normal state, the load circuit 10 can consume excess power of the detection signal, so that the LED directional light group 200 does not generate a slight light. After the load circuit 10 is controlled to be turned off by the protection circuit 20, the directional light control circuit can normally supply power, so that the LED directional light group 200 can normally blink.

而當該LED方向燈組200處於損壞狀態時,LED方向燈組200的電源輸入端201處於迴路斷開狀態,而負載電路10雖然一開始消耗掉偵測信號之電力,但是當保護電路20控制負載電路10斷開後,閃光器100的 偵測電路即能夠正常偵測到該LED方向燈組200無負載而處於損壞狀態,進而令其他方向燈快閃。When the LED directional light group 200 is in a damaged state, the power input terminal 201 of the LED directional light group 200 is in a loop-off state, and the load circuit 10 initially consumes the power of the detection signal, but when the protection circuit 20 controls After the load circuit 10 is disconnected, the flasher 100 The detecting circuit can normally detect that the LED direction light group 200 is in a damaged state without load, and then the other direction lights flash quickly.

圖示中,負載電路10係由若干電阻及電晶體所組成,其中電阻即可以消耗掉閃光器100偵測電路之多餘電力,使該多餘的電力不致於讓LED方向燈組200微亮,而電晶體電連接於保護電路20,當保護電路20施予電晶體一逆向偏壓時,即可以讓負載電路10斷開,以防止負載電路10因持續供電而過熱,同時可以讓閃光器100及LED方向燈組200後續正常運作。In the figure, the load circuit 10 is composed of a plurality of resistors and transistors, wherein the resistors can consume excess power of the flasher 100 detecting circuit, so that the excess power does not cause the LED directional light group 200 to be slightly bright. The transistor is electrically connected to the protection circuit 20. When the protection circuit 20 applies a reverse bias voltage to the transistor, the load circuit 10 can be disconnected to prevent the load circuit 10 from overheating due to continuous power supply, and the flash device 100 can be The LED directional light group 200 is subsequently operated normally.

換言之,藉由本創作LED方向燈之動態負載模組,不但可以使偵測電路能夠偵測到LED方向燈組200是否處於損壞狀態,若LED方向燈組200為正常時,亦可以避免LED方向燈組200因偵測電路所提供的額外電力而產生異常微亮的問題。此外,前述能夠控制負載電路10斷開之保護電路20,實施時如圖所示可以為一時序控制迴路,該時序控制迴路內設有一電容,當電容在設定時間蓄電達到設定值時,即可以導通並且讓負載電路10斷開。In other words, by the dynamic load module of the LED direction light, the detection circuit can detect whether the LED direction light group 200 is in a damaged state, and if the LED direction light group 200 is normal, the LED direction light can also be avoided. The group 200 produces an abnormally bright problem due to the extra power provided by the detection circuit. In addition, the protection circuit 20 capable of controlling the disconnection of the load circuit 10 can be a timing control loop as shown in the figure. The capacitor is provided in the timing control loop. When the capacitor reaches the set value during the set time, Turn on and disconnect the load circuit 10.

如第四圖所示,實施時,本創作動態負載模組與LED方向燈組之間可進一步設置一電源控制模組30,該電源控制模組30包括一連接於LED方向燈組200之電源輸入端201的電源控制單元31、一連接於負載端的輸出功率適配單元32,以及一設置在電源控制單元31與輸出功率適配單元32之間的電源開關33。As shown in the fourth figure, during implementation, a power control module 30 can be further disposed between the dynamic load module and the LED directional light group, and the power control module 30 includes a power source connected to the LED directional light group 200. The power control unit 31 of the input terminal 201, an output power adapter unit 32 connected to the load terminal, and a power switch 33 disposed between the power source control unit 31 and the output power adapter unit 32.

其中,該電源控制單元31包括一設定有最小啟動電壓值的啟動電壓偵測電路、以及一設定有最大啟動電壓值的過壓偵測電路,使電源輸入端201的輸入電壓小於所述最小啟動電壓值或大於最大啟動電壓值 狀態下,該電源開關33為不導通狀態而不供電至功率適配單元32,使LED方向燈組200不作動,進而防止低壓弱電致使LED方向燈組200誤動作。The power control unit 31 includes a startup voltage detection circuit configured with a minimum startup voltage value, and an overvoltage detection circuit configured with a maximum startup voltage value, such that the input voltage of the power input terminal 201 is less than the minimum startup. Voltage value is greater than the maximum starting voltage value In the state, the power switch 33 is in a non-conducting state and is not supplied to the power adapting unit 32, so that the LED directional light group 200 is not activated, thereby preventing the low voltage weak current from causing the LED directional light group 200 to malfunction.

而當電源輸入端201的輸入電壓大於所述最小啟動電壓值並且小於所述最大啟動電壓值狀態下,令該電源開關33為開通狀態,以通過輸出功率適配單元32依負載需求供應電源至LED方向燈組200,藉此以防止高電壓突波對LED方向燈組200造成損壞。When the input voltage of the power input terminal 201 is greater than the minimum starting voltage value and less than the maximum starting voltage value, the power switch 33 is turned on to supply power to the output power matching unit 32 according to the load demand. The LED directional light group 200 is thereby used to prevent damage to the LED directional light group 200 caused by high voltage surges.

如第五圖所示,本創作實施時,保護電路20亦可以為一藉由齊納二極體而能偵測負載電路10之電壓的電壓偵測迴路,當齊納二極體因負載電路10之電壓超過一額定電壓時,即可以施予前述負載電路10之電晶體一逆向偏壓,令負載電路10斷開。以上第三、五圖之保護電路20利用電容或齊納二極體等各種電子元件來控制的方式為一般可以等效運用的基本電路,在此不另贅述。As shown in the fifth figure, during the implementation of the present invention, the protection circuit 20 can also be a voltage detection loop capable of detecting the voltage of the load circuit 10 by a Zener diode, when the Zener diode is loaded by the load circuit. When the voltage of 10 exceeds a rated voltage, a reverse bias of the transistor of the load circuit 10 can be applied to disconnect the load circuit 10. The protection circuit 20 of the third and fifth figures above is controlled by various electronic components such as a capacitor or a Zener diode, and is generally a basic circuit that can be equivalently used, and will not be further described herein.

如第六圖所示,同樣的,本實施例動態負載模組與LED方向燈組之間亦可進一步設置一電源控制模組30,該電源控制模組30包括一連接於LED方向燈組200之電源輸入端201的電源控制單元31、一連接於負載端的輸出功率適配單元32,以及一設置在電源控制單元31與輸出功率適配單元32之間的電源開關33,藉此以達成如前所述防止低壓弱電致使LED方向燈組200誤動作,或高電壓突波對LED方向燈組200造成損壞之功效。As shown in the sixth embodiment, a power control module 30 may be further disposed between the dynamic load module and the LED directional light group. The power control module 30 includes a light source group 200 connected to the LED. The power control unit 31 of the power input terminal 201, an output power adapting unit 32 connected to the load end, and a power switch 33 disposed between the power control unit 31 and the output power adapting unit 32, thereby achieving The prevention of the low voltage weak current causes the LED directional light group 200 to malfunction, or the high voltage spurt to cause damage to the LED directional light group 200.

又,為了不影響車輛原有的方向燈控制電路、閃光器以及偵測電路的運作,本創作之動態負載模組以及電源控制模組可共同安裝在LED方向燈組之電路板上,使本創作能易於實施。Moreover, in order not to affect the operation of the original directional light control circuit, the flasher and the detecting circuit of the vehicle, the dynamic load module and the power control module of the present invention can be jointly mounted on the circuit board of the LED directional light group, so that Creation can be easy to implement.

以上之實施說明及圖式所示,僅係舉例說明本創作之較佳 實施例而已,並非以此侷限本創作;舉凡與上述構造、裝置、特徵等近似或相雷同者,均應屬本創作之創設目的及申請專利範圍之內,謹此聲明。The above description of the implementation and the drawings show only the best examples of the creation.
