Description
本發明涉及一種可攜式LED燈，特別涉及利用一偵測單元的偵測控制而使其具有緊急停電照明等多種照明模式的用途。 The invention relates to a portable LED lamp, in particular to the use of a detection unit for detecting and controlling various illumination modes such as emergency power failure illumination.
一種可攜式LED燈，例如有一種常見的露營LED燈，因其具有可攜帶性所以常被應用於戶外使用。這種露營LED燈因內建有乾電池(或稱一次性電池)可以啟動點亮LED燈，因此攜帶方便適用於戶內外。 A portable LED lamp, for example, has a common camping LED lamp, which is often used for outdoor use because of its portability. This kind of camping LED light can start to illuminate the LED light because of built-in dry battery (or disposable battery), so it is convenient to carry around indoors and outdoors.
但是，這種露營LED燈因為人們環保意識的觀念加深以及人們使用的習慣，對於電池耗盡時大多數人懶得外出另行購買電池。 However, this kind of camping LED lights because people's concept of environmental awareness deepens and people use habits, most people are too lazy to go out and buy batteries separately when the battery is exhausted.
近年來，可充電電池開始被人們大量使用，例如像有智慧型手機等耗電的日常生活用的電子產品。 In recent years, rechargeable batteries have begun to be used in large numbers, such as electronic products for daily use, such as smart phones.
對於戶內常用的一般緊急停電照明燈，其功能係在遇到停電時，可立即啟動其照明燈內備用的可充電電池點亮其照明燈。然而，在非停電期間其照明燈幾乎發揮不了作用，如圖1所示。通常適用於營業場所，例如銀行與商店。 For general emergency blackout lights commonly used indoors, the function is to immediately activate the rechargeable rechargeable battery in the illuminator to illuminate its illuminator when a power outage occurs. However, its illuminator can hardly function during non-blackout periods, as shown in Figure 1. Usually used in business locations such as banks and stores.
另外，如一般斷電延時照明燈(或稱不斷電裝置)，其功能係指照明燈點亮期間若突然遇上停電，則其照明燈內備用的可充電電池，可用以持續地點亮其照明燈，直到其可充電電池的電量耗盡，如圖1A所示。通常適用於工廠生產線上，或醫院手術房。 In addition, if the general power-off delay lighting (or uninterruptible power device), the function means that if the power failure suddenly occurs during the lighting of the light, the rechargeable rechargeable battery in the light can be used to continuously light up the light. The light is turned on until its rechargeable battery is exhausted, as shown in Figure 1A. Usually suitable for factory production lines, or hospital operating rooms.
再次，如一般可攜帶式(不可或可以充電者)照明燈，係指啟動(on)電源開關供電時可點亮其照明燈，而在關閉(off)電源開關不供電時熄滅其照明燈，如圖1B所示。通常例如手電筒。 Again, as a general portable (non-rechargeable or rechargeable) light, it means that when the power switch is turned on, the light can be turned on, and when the power switch is off, the light is turned off. As shown in Figure 1B. Usually for example a flashlight.
又，目前如一般可調光的照明燈，其功能係使在供電點亮其照明燈時，也可調節其照明燈之照明亮度，如圖1C所示。通常適用於閱讀燈。 Moreover, at present, as a general dimmable illumination lamp, its function is to adjust the illumination brightness of the illumination lamp when the illumination is turned on, as shown in FIG. 1C. Usually suitable for reading lights.
如上述的各種照明燈，因使用場所與使用需求的不同，而各自存在。幾乎沒有或不容易(會增加不少製作成本)組合所有功能(如圖1至圖1C)於一身的同一只照明燈。 Various types of illumination lamps as described above exist separately depending on the place of use and the needs of use. There is little or no difficulty (which will add a lot of production costs) to combine all the functions (Figure 1 to Figure 1C) in one light.
本實施例乃試圖將一種可攜式LED燈(例如露營LED燈)改良成這種可以組合上述多種功能於一身的一種露營LED照明燈。 This embodiment attempts to improve a portable LED lamp (such as a camping LED lamp) into such a camping LED illuminator that can combine the above various functions.
電池通常可以將化學能轉化為電能或電壓，因此如果某種電池的能量可以恢復，則此電池稱為二次電池或可充電電池。目前一般可攜帶的LED燈中常用的電池是鎳氫(NiMH)電池和鋰離子(Li-Ion)電池。兩者相比，鋰離子電池具有更好的特性。例如，每節電池的標準電壓更高、自放電率更低、品質能量密度與體積能量密度更高，這使它們對於有需求的應用上更具吸引力。近年來有改用成本較高的鋰離子(Li-ion)電池取代鎳氫電池，因其具有輸出電壓高、比能量高、放電電壓穩定、工作溫度範圍寬、自放電率低、儲存壽命長、無記憶效應等優點，應用越來越廣泛，特別是手機的小型化及普及，使鋰離子電池用量猛增。為了適應各種不同的可擕式電子產品的需要，除單節鋰離子電池外，還有2~4節鋰離子電池組成的電池組。 A battery can usually convert chemical energy into electrical energy or voltage, so if the energy of a certain battery can be recovered, the battery is called a secondary battery or a rechargeable battery. The commonly used batteries in currently available LED lamps are nickel-hydrogen (NiMH) batteries and lithium-ion (Li-Ion) batteries. Lithium-ion batteries have better characteristics than the two. For example, each cell has a higher standard voltage, lower self-discharge rate, higher quality energy density and volumetric energy density, making them more attractive for demanding applications. In recent years, Li-ion batteries have been replaced by high-cost lithium-ion batteries because of their high output voltage, high specific energy, stable discharge voltage, wide operating temperature range, low self-discharge rate and long storage life. The advantages of no memory effect, more and more applications, especially the miniaturization and popularization of mobile phones, so that the use of lithium-ion batteries soared. In order to meet the needs of a variety of portable electronic products, in addition to a single-cell lithium-ion battery, there are battery packs of 2 to 4 lithium-ion batteries.
鋰離子電池保護器IC有適用于單節的及2~4節電池組的。其內部有過充電、過放電、過電流保護的延時電路，防止瞬態干擾造成誤動作；保護器電路簡單，週邊元器件少，占空間小，市售產品有做在電池或電池組中者。 Lithium-ion battery protector ICs are available in single-cell and 2~4 battery packs. The internal delay circuit of overcharge, overdischarge and overcurrent protection prevents the transient interference from causing malfunction; the protector circuit is simple, the peripheral components are small, and the space is small, and the commercially available products are made in the battery or the battery pack.
雖然市場上大部份所用的都是鋰電池，但是依照成分又有分為鋰離子(lithium-ion)電池和鋰聚合物(Li-polymer)電池兩種，兩者的區別在於內部使用的電解質不同，鋰離子電池內部為液體的電解質，而鋰聚合物電池內部為固體聚合物或是膠狀聚合物。 Although most of the batteries used in the market are lithium batteries, they are divided into lithium-ion batteries and lithium-ion batteries according to their composition. The difference between the two is the electrolyte used internally. Differently, the interior of the lithium ion battery is a liquid electrolyte, and the interior of the lithium polymer battery is a solid polymer or a gel polymer.
較高級產品用的鋰離子電池監控器除了有保護電路外(可保護電池在充電、放電過程免於過充電、過放電和過熱)，並且能輸出電池剩餘能量信號(用LCD顯示器可形象地顯示出電池剩餘能量)，使用者能隨時瞭解電池的剩餘能量狀態，以便及時充電或更換電池。它主要用於有μC或μP的可擕式電子產品中，如手機、攝像機、照相機、醫療儀器或音、視頻裝置等。 The lithium-ion battery monitor for higher-grade products not only has a protection circuit (which protects the battery from overcharging, over-discharging and overheating during charging and discharging), but also outputs residual energy signal of the battery (displayed visually by LCD display) The remaining energy of the battery) allows the user to know the remaining energy status of the battery at any time in order to charge or replace the battery in time. It is mainly used in portable electronic products with μC or μP, such as mobile phones, video cameras, cameras, medical instruments or audio and video devices.
本實施例乃試圖將一種可攜式LED燈改良成可以具有多種功能於一身的一種露營LED照明燈。其中利用一可對「外部直流電源輸入」偵測的偵測單元與其簡單的控制電路，使得這種露營LED照明燈可攜帶外出使用以外，兼具有所謂室內固定式之緊急停電照明燈與斷電延時照明燈等多功能用途者。 This embodiment attempts to improve a portable LED lamp into a camping LED illuminator that can have multiple functions. The detection unit and the simple control circuit for detecting the "external DC power input" enable the camping LED illumination lamp to be carried out and have the so-called indoor fixed emergency power failure illumination and off Multi-purpose users such as electric delay lamps.
本實施例的一種露營LED照明燈(以下簡稱露營燈)，其中利用一直流電繼電器(Relay)作為一種偵測「外部直流電源輸入」的偵測單元，用以偵測露營燈除了內建的工作電源(或稱備用電池)以外，是否還有另外的外部直流電源輸入？其目的係用以辨識與啟動露營燈不同照明的模式。 A camping LED lighting device (hereinafter referred to as a camping light) of the embodiment, wherein a relay device is used as a detecting unit for detecting an "external DC power input" for detecting a camping lamp in addition to the built-in work. Is there any additional external DC power input besides the power supply (or backup battery)? The purpose is to identify patterns that are different from the lighting that activates the camping light.
其中，外部直流電源(以下或簡稱外電源)的輸入，一方面表示本露營燈須要充電了；另一方面表示有市電源的加入。其中，市電源的加入係指本露營燈已連接上室內的家用電源。因此，藉由偵測家用電源的加入與否，也就可以間接偵測到家用電源「是否已停電」？若已停電則本露營燈啟動其具有緊急停電照明等的功能者。 Among them, the input of the external DC power supply (hereinafter referred to as the external power supply), on the one hand, indicates that the camping light needs to be charged; on the other hand, it indicates that the city power supply is added. Among them, the addition of the city power supply refers to the household power supply that the camping light has been connected to the indoor. Therefore, by detecting the addition of household power, it is possible to indirectly detect whether the household power supply has been powered off. If the power has been cut off, the camping light starts its function with emergency power-off lighting.
露營燈適用於室內外，其裝置至少包含：一LED燈， 其係一種可攜帶式LED燈；一偵測單元，其可偵測該LED燈是否有外部電源輸入；一備用電池，其可提供該LED燈照明的電源；一第一切換開關，其用以啟動備用電池執行充電或放電的動作；一第二切換開關，其用以啟動該LED燈執行緊急停電照明或斷電延時照明模式的功能；一外部電源輸入埠，其可輸入外部電源。 The camping light is suitable for indoor and outdoor use, and its installation includes at least: an LED light. It is a portable LED lamp; a detecting unit that can detect whether the LED lamp has an external power input; a backup battery that can provide power for the LED lamp illumination; and a first switch that is used for The backup battery is activated to perform charging or discharging; a second switching switch is used to activate the LED lamp to perform an emergency power-off illumination or power-off delay illumination mode; and an external power input port, which can input an external power source.
本露營燈的改良在於：藉由其偵測單元的偵測外部電源動作與其等切換開關的切換動作，使此露營燈具有可攜式照明燈的功能，進一步具有傳統固定式的緊急停電照明燈與斷電延時照明燈的功能。 The improvement of the camping light is that the camping light has the function of a portable lighting lamp by the detecting unit's detecting external power action and the switching action of the switch, and further has a traditional fixed emergency power failure lamp. With the function of power-off delay lighting.
本露營燈利用一直流電繼電器作為一種偵測「外電源輸入」的偵測單元，加上一只旋轉開關型的可變電組與兩只簡單切換開關的切換動作，在其他實施例中，也有在其備用電池的迴路串一正溫度系數的熱敏電阻PTC(positive temperature coefficient)，這種感溫材料的阻抗會隨溫度的增加而變大，也就是說，其電流為溫度的函數。當電路正常工作時，熱敏電阻溫度與室溫相近、電阻很小，串聯在電路中不會阻礙電流通過；而當電路因出現過電流時，熱敏電阻由於發熱功率增加導致溫度上升，當溫度超過所預定的溫度時，電阻瞬間會劇增，回路中的電流迅速減小到安全值，熱敏電阻動作後，備用電池電路中電流有了大幅度的降低，這就以溫度過高時簡單的保護備用電池方法，本實施例溫度的控制約在6~10度C，應用時應依其備用電池的安規而定之。 The camping light utilizes a constant current relay as a detecting unit for detecting an "external power input", and a switching operation of a rotary switch type variable electric unit and two simple switching switches. In other embodiments, there are also In the loop of the backup battery, a positive temperature coefficient of the thermistor PTC (positive temperature coefficient), the impedance of the temperature sensing material will become larger as the temperature increases, that is, its current is a function of temperature. When the circuit works normally, the thermistor temperature is close to room temperature and the resistance is very small. The series connection in the circuit does not hinder the current from passing through. When the circuit is overcurrent, the thermistor increases the temperature due to the increase of the heating power. When the temperature exceeds the predetermined temperature, the resistance will increase sharply, and the current in the circuit will rapidly decrease to a safe value. After the thermistor is operated, the current in the backup battery circuit is greatly reduced, which is when the temperature is too high. The method of protecting the backup battery is simple. The temperature control in this embodiment is about 6~10 degrees C. The application should be based on the safety regulations of the backup battery.
藉由上述：一直流電繼電器、一只旋轉開關型的可變電組、兩只簡單切換開關的切換與一PTC，就可使本露營燈兼具有如手電筒、閱讀燈、緊急停電照明燈與斷電延時照明燈等多功能的用途。 By the above: a constant current relay, a rotary switch type variable power group, two simple switching switches, and a PTC, the camping light can be combined with a flashlight, a reading light, an emergency power failure light and a light. Multi-purpose use such as electric delay lamps.

為便利說明本實施例LED燈與一般室內外用之LED燈的照明用途，於下列各圖(第圖1至第圖1D)示之說明，其中縱座標分別標示為電源啟用動作與照明燈點亮動作，以如下矩形直線圖之表示；其中橫座標係標示為動作時間以如下矩形斜線圖相對的長短表示之。 In order to facilitate the description of the illumination use of the LED lamp of the present embodiment and the LED lamp for general indoor and outdoor use, the following figures (Fig. 1 to Fig. 1D) are illustrated, wherein the ordinate is marked as the power activation action and the illumination lamp is respectively illuminated. The action is represented by a rectangular line diagram as follows; wherein the abscissa is indicated as the action time expressed by the relative length of the following rectangular slash diagram.
如第1圖，一般固定壁掛式的緊急停電照明燈的功能，係指當其AC(交流市電)供電(圖中畫直線方塊圖)時，其照明燈不亮(圖中空白未畫直線部份)。停電(圖中空白未畫斜線部份)時，可立即緊急啟動其照明燈內備用的可充電電池點亮(圖中畫斜線方塊圖)其照明燈。 As shown in Figure 1, the function of the general fixed wall-mounted emergency power-off illuminator means that when its AC (AC mains) power supply (pictured in the figure), the illuminating light does not illuminate (the blank line is not drawn in the figure). Share). When the power is cut off (the blank part is not drawn in the figure), the rechargeable battery in the illuminator can be immediately activated to illuminate (the slash block diagram in the figure).
一般緊急停電照明燈在非停電期間其幾乎發揮不了 作用。相較本實施例LED照明燈，如第1圖D所示，在非停電期間其可發揮具有「斷電延時照明燈」功能的作用；與其進一步可發揮其具有「露營燈照明」的攜帶方便作用。 Generally, emergency power failure lights can hardly be used during non-blackout periods. effect. Compared with the LED illumination lamp of the present embodiment, as shown in FIG. 1D, it can function as a "power-off delay illumination lamp" during non-blackout periods; and further, it can be conveniently carried with "camping light illumination". effect.
如第1圖A，一般固定式的「斷電延時照明燈」的功能，係指當其AC供電時，其照明燈也點亮。停電時，其照明燈更可藉由內部備用的可充電電池「持續」點亮其照明燈，直點亮到備用電池耗盡為止。相較本實施例LED照明燈，如第1圖D所示，其可更發揮其具有「緊急停電照明燈」功能的作用；與其進一步可發揮其具有「手電筒照明或露營燈照明」的攜帶方便作用。 As shown in Fig. 1A, the function of the general fixed "power-off delay light" means that when its AC power is supplied, its illumination light also illuminates. In the event of a power outage, the illuminator can be "continuously" illuminated by an internal rechargeable battery to illuminate until the backup battery is exhausted. Compared with the LED illumination lamp of the present embodiment, as shown in FIG. 1D, it can further function as an "emergency power failure lighting" function; and further, it can be conveniently carried with "flashlight illumination or camping light illumination". effect.
如第1圖B，一般活動式的「露營燈照明燈」，係指當其裝置本身供電(ON)時，其照明燈點亮；不供電(OFF)時，其照明燈不亮。這種單純供電照明，尚無法同時具有「斷電延時照明燈」與「緊急停電照明燈」的功能。相較本實施例LED照明燈，如第1圖D所示，其同時具有「斷電延時照明燈」與「緊急停電照明燈」的功能。 As shown in Fig. 1B, the general movable "camping light" means that when the device itself is powered (ON), its illumination light is on; when it is not powered (OFF), its illumination is not lit. This kind of purely powered lighting does not have the functions of "power failure delay light" and "emergency power failure light" at the same time. Compared with the LED illumination lamp of the present embodiment, as shown in FIG. 1D, it has the functions of "power failure delay illumination" and "emergency power failure illumination".
如第1圖C，一般固定式的「閱讀照明燈」，係指當其供電(ON)時，點亮照明燈的照度可被調整為不同照度範圍的調光功能。也就是說，其可藉由一簡單的可變電阻器或PWM控制器被調整為不同照度範圍的亮暗光照。這種單純閱讀照明，尚無法同時具有「斷電延時照明燈」、「緊急停電照明燈」與「手電筒照明燈」的功能。相較本實施例LED照明燈，如第1圖D所示，其同時具有「斷電延時照明燈」、「緊急停電照明燈」與「露營照明燈」的功能。 As shown in Fig. 1C, a generally fixed "reading light" refers to a dimming function in which the illuminance of the illuminating light can be adjusted to different illuminance ranges when it is powered (ON). That is, it can be adjusted to bright and dark illumination of different illumination ranges by a simple variable resistor or PWM controller. This simple reading illumination does not have the functions of "power failure delay light", "emergency power failure light" and "flashlight light" at the same time. Compared with the LED illumination lamp of the present embodiment, as shown in FIG. 1D, it has the functions of "power failure delay illumination", "emergency power failure illumination" and "camping illumination".
如第1圖D，本實施例涉及一種可攜帶式的LED燈裝置，其中利用一可對外電源偵測的偵測單元，使其具有室內固定式之緊急停電照明燈與斷電延時照明燈的功能以及；使其具有室外活動式之可調光照明的功能。 As shown in FIG. 1D, the embodiment relates to a portable LED lamp device, wherein a detection unit capable of detecting an external power source is provided with an indoor emergency type emergency power failure illumination lamp and a power failure delay illumination lamp. Features as well as the ability to have outdoor active dimmable lighting.
請參閱第2圖係本實施例所述外部直流電源之示意圖 與；請參閱第2圖A係本實施例所述外部直流電源之示意圖一。 Please refer to FIG. 2, which is a schematic diagram of the external DC power supply according to the embodiment. And FIG. 2 is a schematic diagram 1 of the external DC power supply according to the embodiment.
如第2圖，本實施例所述之外部直流電源包含：一種經由交流高壓(例如AC110~240V)電轉變交流低壓(例如AC5V)電再整流出的直流電源，例如像似為市售的一只適配器(Adaptor)。其之所以為外部直流電源，係指可攜帶式的LED燈之裝置外部的電源，主要用以區分LED燈裝置內部的備電電池。在本發明的一實施例中，係在市場上選購了一單節可充電的鋰離子電池(Li-ion)與其充電器。其充電器的規格係為AC110~240V轉成DC5V，其電流為1A的適配器。此充電器其主要係對單節3.6V1.6AH的鋰離子電池提供一種安全的充電裝置。 As shown in FIG. 2, the external DC power supply according to the embodiment includes: a DC power source that is re-converted by an AC high voltage (for example, AC 110 to 240 V) to convert an AC low voltage (for example, AC 5 V), for example, a commercially available one. Only adapter (Adaptor). The reason why it is an external DC power supply refers to a power supply external to the device of the portable LED lamp, and is mainly used to distinguish the backup battery inside the LED lamp device. In an embodiment of the invention, a single rechargeable lithium ion battery (Li-ion) and its charger are commercially available. The specification of the charger is AC110~240V converted to DC5V, and its current is 1A adapter. This charger mainly provides a safe charging device for a single 3.6V1.6AH lithium-ion battery.
單節3.6V1.6AH的鋰離子電池其充放電要求較高，其最高充電終止電壓應為4.2V，不能過充。其放電終止電壓通常為3.0V/節，最低不能低於2.5V/節。電池放電時間長短與電池容量、放電電流大小有關。如第2圖，本實施例採用市售鋰離子電池充電器，再將充電器拆開分為兩部份：前部份為本實施例所述之外部直流電源20；後部份為本實施例電路圖所述之電池(係包含一顆單節3.6V1.6AH的鋰離子電池與其充放電保護電路板)。 A single-cell 3.6V1.6AH lithium-ion battery has a higher charge and discharge requirement, and its maximum charge termination voltage should be 4.2V, which cannot be overcharged. The discharge termination voltage is usually 3.0V/section, and the minimum cannot be lower than 2.5V/section. The length of battery discharge is related to the battery capacity and discharge current. As shown in Fig. 2, this embodiment uses a commercially available lithium ion battery charger, and then the charger is split into two parts: the former part is the external DC power supply 20 described in the embodiment; the latter part is the implementation The battery shown in the circuit diagram (containing a single 3.6V1.6AH lithium-ion battery and its charge and discharge protection circuit board).
如第2圖A，本實施例所述之外部直流電源20，其輸出的正電源以圓圈內數字1(或簡稱數字1)表示與；其輸出的負電源以圓圈內數字2(或簡稱數字2)表示。 As shown in FIG. 2A, the external DC power supply 20 of the embodiment has a positive power supply outputted by a circle 1 (or abbreviated as 1); and a negative power supply of the output is a circle 2 (or abbreviated as a number). 2) indicates.
本實施例的露營燈涉及電源之參數，主要涉及有LED燈的電源功率、外部直流電源提供的電流與本露營燈裝置內置的可充電電池(以下簡稱為備用電池)規格。尤其，其備用電池所能承受的最大充電電流，以及充電時的溫度範圍，並利用這些參數來調整所需的外部直流電源。 The camping lamp of this embodiment relates to the parameters of the power source, and mainly relates to the power of the LED lamp, the current supplied by the external DC power source, and the specifications of the rechargeable battery (hereinafter referred to as the backup battery) built in the camping lamp device. In particular, the maximum charging current that the backup battery can withstand, as well as the temperature range during charging, and use these parameters to adjust the external DC power required.
本實施例之一採用的備用電池為鋰離子電池，部份實施例中也採用鋰聚合物電池與鋰鐵(LiFePO4)等單價較高的備用電池， 此等備用電池在本實施例中定義為鋰系電池。一般鋰離子電池的基本架構圖，有一個溫度偵測器，其主要功用在於告知充電器現在的溫度是否超過安全範圍，本實施例的其他例也曾利用一熱敏電阻的配合來達成此一目的。 The backup battery used in one embodiment of the present invention is a lithium ion battery. In some embodiments, a lithium battery battery and a lithium battery (LiFePO 4 ) are also used. The backup batteries are defined in this embodiment. It is a lithium battery. The basic architecture diagram of a general lithium-ion battery has a temperature detector. Its main function is to inform the charger whether the current temperature exceeds the safe range. Other examples in this embodiment have also used a thermistor to achieve this. purpose.
在實施例中，所採用的外部直流電源所輸出的電壓最好接近備用電池飽和電壓的1.1倍較加。 In an embodiment, the voltage output by the external DC power source is preferably close to 1.1 times the saturation voltage of the backup battery.
其中本露營燈是購自市售的露營LED燈加以改良之，其內部使用的電源是三顆3號的乾電池，本實施例係將其電池座內的三顆3號乾電池取出後，直接置入一顆單節3.6V1.6AH的鋰離子電池。 The camping light is improved from the commercially available camping LED lamp, and the power source used therein is three No. 3 dry batteries. In this embodiment, the three No. 3 dry batteries in the battery holder are taken out and directly placed. Into a single 3.6V1.6AH lithium-ion battery.
根據實施例所採用鋰電池的結構特性，本實施例採用專用的恒流、恒壓充電器進行充電。至於充電器的結構設計應以安全為考量，因其中涉及充電器的保護電路板等並非本露營燈之專利請求項，因此不再詳述之。 According to the structural characteristics of the lithium battery used in the embodiment, the present embodiment uses a dedicated constant current and constant voltage charger for charging. As for the structural design of the charger, it should be considered for safety. Because the protection circuit board of the charger is not the patent request item of the camping lamp, it will not be described in detail.
請參閱第3圖係本實施例電路控制之示意圖。 Please refer to FIG. 3 for a schematic diagram of circuit control of this embodiment.
如第3圖，外部直流電源的輸出中，以圓圈內數字1(或簡稱數字1)表示正電與；以圓圈內數字2(或簡稱數字2)表示負電。 As shown in Fig. 3, in the output of the external DC power supply, the number 1 (or simply the number 1) in the circle indicates positive power; and the number 2 (or simply 2) in the circle indicates negative power.
首先，當外部直流電源「無」輸入時： First, when the external DC power supply is "none" input:
如第3圖，因外部直流電源無輸入，所以電路中數字1的正電與數字2的負電均無電源。如果要點亮LED燈，僅有啟動其備用電池。 As shown in Figure 3, since there is no input from the external DC power supply, there is no power supply for the positive of the digital 1 and the negative of the digital 2 in the circuit. If you want to illuminate the LED light, only activate its backup battery.
如第3圖，，將SW1切換到「放電」模式，使備用電池的電流向LED燈(LEDS)。這時，若SW3/VR(帶開關的可變電阻器)轉到「ON」的位置(以下本實施例未特別聲明時均設定其位置為ON位置)即可點亮LED燈，若繼續轉動則因電阻數值逐漸變小而使得LED燈逐漸變亮。一直亮到備用電池的「電流耗盡」。這就是所謂的手電筒與露營燈照明模式，可自由攜帶又可調光的照明模式。 As shown in Fig. 3, SW1 is switched to the "discharge" mode, and the current of the backup battery is directed to the LED lamp (LEDS). At this time, if SW3/VR (variable resistor with switch) is turned to the "ON" position (the position is set to the ON position when not specifically stated in the following embodiment), the LED lamp can be lit, and if it continues to rotate, The LED light gradually becomes brighter as the resistance value becomes smaller. It is always on until the battery is exhausted. This is the so-called flashlight and camping light lighting mode, free to carry and dimmable lighting mode.
上述所謂的電流耗盡其中的「耗盡」並非是全部完全地耗掉，依部份可充電電池廠商規定，當其可充電電池的電量降低至約20%時設計為安全使用底限，已被保護電路設置。因此，本實施例後述之「耗盡」指廠商規定的安全使用底限。否則，耗盡後將不易再可充電。 The so-called "depletion" of the so-called current depletion is not completely consumed. According to some rechargeable battery manufacturers, when the rechargeable battery is reduced to about 20%, it is designed to be a safe use limit. Protected circuit settings. Therefore, the "depletion" described later in this embodiment refers to the safe use limit specified by the manufacturer. Otherwise, it will not be easy to recharge after exhaustion.
如第3圖，在其備用電池的迴路串一正溫度系數的熱敏電阻PTC(positive temperature coefficient)，而當電路因出現(故障)過電流時，熱敏電阻PTC由於發熱功率增加導致溫度上升，當溫度超過所預定的溫度時，電阻瞬間會劇增，回路中的電流迅速減小到安全值，熱敏電阻動作後，備用電池電路中電流有了大幅度的降低，也就是說，不再或停止備用電池的充電動作，這就以溫度過高時簡單的保護備用電池方法，本實施例溫度的控制約在6~10度C，應用時應依其備用電池的安規而定之。 As shown in Fig. 3, the circuit of the backup battery has a positive temperature coefficient PTC (positive temperature coefficient), and when the circuit has an overcurrent due to (fault), the thermistor PTC increases in temperature due to an increase in heating power. When the temperature exceeds the predetermined temperature, the resistance will increase sharply, and the current in the circuit will rapidly decrease to a safe value. After the thermistor is operated, the current in the backup battery circuit is greatly reduced, that is, no Then, the charging operation of the backup battery is stopped, which is a simple method for protecting the backup battery when the temperature is too high. The temperature control in this embodiment is about 6 to 10 degrees C, and the application should be determined according to the safety regulations of the backup battery.
當外部直流電源「有」輸入時： When the external DC power supply has "Yes" input:
如第3圖，外部直流電源的正負電由圖之右側的數字1、2進入後，跨接正負電源的偵測單元是一直流繼電器(DC Relay)RL則也啟動以及；其正電源就分成兩迴路： As shown in Figure 3, the positive and negative power of the external DC power supply enters the numbers 1 and 2 on the right side of the figure. The detection unit that connects the positive and negative power supplies is the DC Relay RL, and the positive power is divided. Two loops:
第一迴路經一第一切換開關SW1的切換，可以對該備用電池為執行充電的動作。 The first circuit is switched by a first switch SW1 to perform charging operation on the backup battery.
第二迴路經一第二切換開關SW2的切換可啟動該LED燈具有執行緊急停電照明模式與斷電延時照明模式的功能。經SW2開關，再經繼電器RL的一組常開接點(Normal open)R/2的導通可點亮LED照明燈(以下簡稱照明燈或是LED燈)。 The switching of the second circuit via a second switch SW2 can activate the function of the LED lamp to perform an emergency power-off illumination mode and a power-off delay illumination mode. After the SW2 switch, the conduction of a set of normally open contacts R/2 of the relay RL can illuminate the LED illumination lamp (hereinafter referred to as the illumination lamp or the LED lamp).
其中，SW2開關為導通時，正電源經過一繼電器RL之一常開接點(Normal close)R/2的導通點亮LED燈。這種情況稱為「斷電延時照明」模式，也就是說，當提供外部直流電源的市電停電時，其備用電池在放電模式下的放電模式可持續點LED燈。 Wherein, when the SW2 switch is turned on, the positive power supply illuminates the LED light through a normally closed contact (R02) of a relay RL. This situation is called the "power-off delay lighting" mode, that is, when the mains supply of the external DC power supply is cut off, the discharge mode of the backup battery in the discharge mode can continue to be the LED light.
其中，SW2開關不導通時，正電源被斷路而無法點亮LED燈。這種情況稱為「緊急停電照明」模式，也就是說，當提供外部直流電源的市電停電時，其備用電池在放電模式下，才開始放電以點亮LED燈。 When the SW2 switch is not turned on, the positive power supply is disconnected and the LED light cannot be turned on. This situation is called the "emergency power-off lighting" mode. That is to say, when the mains supply of the external DC power supply is cut off, the backup battery starts to discharge in the discharge mode to illuminate the LED lamp.
第一迴路經SW1(切換為充電與放電兩種模式)開關的不動作，對備用電池進行充電動作。 The first circuit is charged by the switch of SW1 (switching to the charging and discharging modes) and charging the backup battery.
當SW1動作時(放電模式)，備用電池放電可出點亮LED燈，但是，因為其繼電器RL之一常閉接點R/1的斷路無法點亮LED燈。也就是說，當繼電器RL不動作或是說當無外部直流電源輸入(停電狀態)時，備用電池的放電動作始可點亮LED燈。 When SW1 is operating (discharge mode), the backup battery discharges to illuminate the LED lamp, but the LED lamp cannot be lit because one of the relays RL is normally closed. That is to say, when the relay RL does not operate or when there is no external DC power input (power-off state), the discharge operation of the backup battery can illuminate the LED lamp.
本實施例的LED燈係採用單節鋰離子電池。但也不排除採用鋰離子電池組成的電池組。 The LED lamp of this embodiment adopts a single-cell lithium ion battery. However, a battery pack composed of a lithium ion battery is not excluded.
如先前技術所述之鋰離子電池，其內部都有過充電、過放電、過流保護的延時電路，防止瞬態干擾造成誤動作的保護器電路，均非為本實施例的專利申請範圍，在此不另詳述。 The lithium ion battery as described in the prior art has a delay circuit for overcharge, overdischarge, and overcurrent protection inside, and a protector circuit for preventing malfunction caused by transient interference is not the scope of patent application of the present embodiment. This is not detailed.
請參閱第4圖係本實施例照明燈動作流程之示意圖。 Please refer to FIG. 4, which is a schematic diagram of the operation flow of the illumination lamp of this embodiment.
如第4圖，圖中START表示本動作流程開始，首先，照明動作會由偵測單元進行偵測工作，偵測是否有外部直流電源由照明燈的電源輸入埠輸入；若是：則外部直流電源(如第2圖電路圖所示)流經分成兩迴路：第一迴路經其備用電池決定是否對備用電池執行充電的動作。如果是，就充電；如果否，就放電。 As shown in Figure 4, the START indicates the beginning of this action flow. First, the illumination action is detected by the detection unit to detect whether an external DC power source is input from the power input of the illumination lamp; if it is: the external DC power supply (As shown in the circuit diagram in Figure 2), the flow is divided into two loops: the first loop determines whether to charge the backup battery via its backup battery. If it is, it will be charged; if not, it will be discharged.
當備用電池進行執行放電的動作時，可以點亮照明燈。 When the backup battery performs the action of discharging, the illumination lamp can be lit.
第二迴路經選擇是否選擇「斷電延時照明」模式(或稱為不斷電模式)？ The second loop is selected whether to select the "power-off delay lighting" mode (or called the uninterruptible power mode)?
若是，第二迴路電流經「斷電延時照明」模式的選擇開關(如第3圖SW2開關)。使照明燈通電可點亮Leds lamp表示的照明燈。這時，當「斷電延時照明」模式下，一旦遇到所謂的「停電」，也就是說外部直流電源停止繼續供電，則此照明燈乃會因備用電池的繼續供電而持續點亮，此稱為「斷電延時照明」模式。 If so, the second loop current is passed through the selection switch of the "Power-off delay illumination" mode (such as the SW2 switch in Figure 3). Powering up the illuminator illuminates the illuminator represented by the Leds lamp. At this time, in the "power-off delay illumination" mode, once the so-called "blackout" is encountered, that is, the external DC power supply stops supplying power, the illumination lamp will continue to be lit due to the continued supply of the backup battery. This is called "Power-off delay lighting" mode.
若否，選擇開關僅有選擇「緊急停電照明」模式，此期間如第3圖的常閉開關斷路，也就是說外部直流電源的供電並無法直接供給照明燈而不能點亮照明燈。但是，當外部直流電源停止供電時，確因為備用電池的「瞬間介入」，提供了照明燈所需的電源而點亮了照明燈。此稱為「緊急停電照明」模式。 If not, the selector switch only selects the "emergency power-off lighting" mode. During this period, the normally closed switch of Figure 3 is open, which means that the external DC power supply cannot directly supply the illumination and cannot illuminate the illumination. However, when the external DC power supply stops supplying power, it is indeed because of the "instantaneous intervention" of the backup battery that the illumination light is supplied by providing the power required for the illumination lamp. This is called the "emergency blackout lighting" mode.
如第4圖的流程，「緊急停電照明」模式必須使備用電池處於放電模式下。 As in the flow of Figure 4, the "emergency power failure lighting" mode must place the backup battery in the discharge mode.
如第4圖的流程與第3圖的電路，備用電池如為2~4節鋰離子電池的電池組，其充電與放電的兩個動作係分別由充電與放電的兩個接口(埠)形成，但如單節鋰離子電池則以一切換開關作切換充電與放電動作。 As shown in the flow chart of FIG. 4 and the circuit of FIG. 3, the backup battery is a battery pack of 2 to 4 lithium-ion batteries, and the two charging and discharging operations are respectively formed by two interfaces (埠) of charging and discharging. However, if a single-cell lithium-ion battery uses a switch to switch charging and discharging operations.
其中，放電動作欲點亮LED燈，其明顯的條件必須是外部直流電源停止(如圖中N字記號處)供電，才由備用電池對LED燈供電。 Among them, the discharge action is to illuminate the LED lamp, and the obvious condition must be that the external DC power supply is stopped (as indicated by the N-mark in the figure), and the LED lamp is powered by the backup battery.
如第4圖的流程，當供電LED燈照明時，可藉由一開關式可變電阻器作為一調光器。例如利用一脈衝寬度調變PWM電路模板或較簡單但效率低的一可變電阻VR電路模板。此PWM電路模板或一可變電阻VR電路模板均係為習知而且有模板成品出售，在此不另說明。 As shown in the flow of Fig. 4, when the power LED is illuminated, a switching variable resistor can be used as a dimmer. For example, a pulse width modulated PWM circuit template or a simple but inefficient one variable resistance VR circuit template is utilized. The PWM circuit template or a variable resistor VR circuit template is conventional and has a template finished product, which is not described here.
如第4圖的流程，其圖中的「LEDS Lamp」係為本實施例之LED照明燈。 As shown in the flow chart of Fig. 4, the "LEDS Lamp" in the figure is the LED illumination lamp of the present embodiment.
藉由上述：一直流電繼電器、一只旋轉開關型的可變 電組、兩只簡單切換開關的切換與一PTC，簡潔又達到多功能的電路設計與實用的流程規劃，使得本實施例的LED燈，不僅具有可攜帶活動式的照明功能，更具有傳統固定式的緊急停電照明燈與斷電延時照明燈等的功能。 By the above: a constant current relay, a rotary switch type variable The switching of the electric group, the two simple switching switches and the PTC, the simple and multi-functional circuit design and the practical flow planning, the LED lamp of the embodiment not only has the portable movable function, but also has the traditional fixed The function of emergency power failure lighting and power failure delay lighting.
