【技术领域】【Technical field】
本发明是涉及一种照明灯具，特别涉及一种停电时可持续发光的停电延时照明灯具。The invention relates to a lighting fixture, in particular to a power failure time-delay lighting fixture which can continuously emit light during a power failure.
【背景技术】【Background technique】
早期在发光二极管(Light Emitting Diode,LED)照明尚未普及前，所有的照明产品每瓦所能产生的照度不大。因此，为了获得足够的照度，就必须增加照明灯具的瓦数，在这情况下也就直接增加了照明使用的耗电量。In the early days, before Light Emitting Diode (LED) lighting was popularized, all lighting products could produce little illuminance per watt. Therefore, in order to obtain sufficient illuminance, it is necessary to increase the wattage of the lighting fixture, and in this case, it directly increases the power consumption of the lighting.
过去为了要达到停电时具有紧急照明的功能，肇因于传统灯具的大功率耗电，其所采用的充电电池的容量都非常的大，甚至部份紧急照明系统还使用传统的铅酸电瓶作为储能电池，不但重量重，放电效能与使用寿命都不佳。In the past, in order to achieve the function of emergency lighting during power failure, due to the high power consumption of traditional lamps, the rechargeable batteries used in them have a very large capacity, and even some emergency lighting systems use traditional lead-acid batteries as Energy storage batteries are not only heavy, but also have poor discharge performance and service life.
传统的照明灯具多以冷阴极管或是钨丝灯炮等做为光源，前者是透过高压驱动方式启动，后者伴随着照明所产生的温度高，能量在热损上浪费太多。应用在紧急照明产品时，若想降低照明亮度以延长有限容量的电池使用寿命，所耗费的电路设计成本更高。因此，过去所见的紧急照明装置，多半是无法调光、降低输出以延长停电时的照明时间。Traditional lighting fixtures mostly use cold-cathode tubes or tungsten bulbs as light sources. The former is activated by high-voltage driving, while the latter is accompanied by high temperature generated by lighting, which wastes too much energy on heat loss. When used in emergency lighting products, if you want to reduce the lighting brightness to prolong the service life of the battery with limited capacity, the cost of circuit design will be higher. Therefore, most of the emergency lighting devices seen in the past cannot be dimmed or reduced in output to prolong the lighting time during power outages.
再者，因应法规的需求，紧急照明系统一般是无法额外再装置切换开关，只能在真正停电时使用，因此通常室内的照明除了安装一般传统照明灯具外，还会再另外安装几套的紧急照明系统，无形中增加了不少的费用。对于大型室内公共场合或商业百货大楼，所产生的费用更为可观。Furthermore, in response to the requirements of laws and regulations, the emergency lighting system generally cannot be equipped with an additional switch, and can only be used during a real power outage. Therefore, in addition to the general traditional lighting fixtures, several sets of emergency lighting systems are usually installed for indoor lighting. The lighting system has virtually increased a lot of costs. For large indoor public places or commercial department stores, the resulting costs are even more considerable.
【发明内容】【Content of invention】

Preferably, the switch 130 is a cut-off switch, which allows the user to switch the lamp on and off.
如图所示，天线140用于侦测所述火线L的一感应电场(图未示)。具体而言，天线140并未直接连接于火线L，而是以无线方式来侦测所述感应电场或电流。在此实施例中，所述天线140为圈线式天线，其缠绕于火线L，用于感应火线L上频率为50赫兹或60赫兹的交流电。As shown in the figure, the antenna 140 is used to detect an induced electric field of the live line L (not shown). Specifically, the antenna 140 is not directly connected to the live line L, but detects the induced electric field or current wirelessly. In this embodiment, the antenna 140 is a coil antenna, which is wound around the live wire L and used for inducting an alternating current with a frequency of 50 Hz or 60 Hz on the live wire L. As shown in FIG.
如图所示，电源分配模块150连接于所述市电20的所述火线L及中性线N，并电性连接于所述灯源110、所述电池模块120及所述天线140。电源分配模块150用于提供所述电池模块120充电及提供所述灯源110发光所需电力。更进一步地说，当所述中性线N为导通状态且所述天线140侦测不到所述火线L的感应电场时，所述电源分配模块150则控制所述电池模块120放电以提供所述灯源110发光所需电力。As shown in the figure, the power distribution module 150 is connected to the live line L and the neutral line N of the commercial power 20 , and is electrically connected to the light source 110 , the battery module 120 and the antenna 140 . The power distribution module 150 is used for charging the battery module 120 and providing the power required for the light source 110 to emit light. Furthermore, when the neutral line N is in a conducting state and the antenna 140 cannot detect the induced electric field of the live line L, the power distribution module 150 controls the battery module 120 to discharge to provide The power required by the light source 110 to emit light.
以下将详细说明本实施例的电源分配模块150的具体架构，请参照图2，图2绘示本发明的优选实施例的电源分配模块的一般照明模式的方块示意图，其中以箭头表示电力传输方向。电源分配模块150包括点灯电路152、充电电路154及电池管理单元156，上述元件可整合于一电路板(图未示)中。The specific architecture of the power distribution module 150 of this embodiment will be described in detail below. Please refer to FIG. 2 , which is a schematic block diagram of the general lighting mode of the power distribution module in a preferred embodiment of the present invention, wherein arrows indicate the direction of power transmission. . The power distribution module 150 includes a lighting circuit 152 , a charging circuit 154 and a battery management unit 156 , which can be integrated into a circuit board (not shown).
所述点灯电路152用于将所述市电20的交流电转换为直流电，以提供给所述灯源110。具体而言，点灯电路152可包括一整流器(rectifier)，其可分类为半波(half-wave)整流与全波(full-wave)整流。请一并参照图1及图2，在一般照明状态时，即当所述中性线N为导通状态且所述天线140侦测所述火线L上的感应电场存在时，所述点灯电路152提供所述灯源110发光所需电力。The lighting circuit 152 is used for converting the alternating current of the mains 20 into direct current to provide to the light source 110 . Specifically, the lighting circuit 152 may include a rectifier, which can be classified into half-wave rectification and full-wave rectification. Please refer to FIG. 1 and FIG. 2 together. In the general lighting state, that is, when the neutral line N is in a conducting state and the antenna 140 detects the presence of an induced electric field on the live line L, the lighting circuit 152 provides the power required for the light source 110 to emit light.
另一方面，所述充电电路154用于将所述市电20的交流电转换为直流电，以对所述电池模块120充电。同样地，点灯电路152可包括一整流器(rectifier)，其可分类为半波(half-wave)整流与全波(full-wave)整流。值得一提的是，在其他实施例中，点灯电路152及充电电路154可整合为单一模块方式实施。类似地，在一般照明状态时，即当所述中性线N为导通状态且所述天线140侦测所述感应电场存在时，所述充电电路154对所述电池模块120充电。也就是说，电源分配模块150在一般照明状态时，除了将市电20的电力提供给灯源110之外，也提供给电池模块120进行充电。On the other hand, the charging circuit 154 is used for converting the alternating current of the mains 20 into direct current to charge the battery module 120 . Likewise, the lighting circuit 152 may include a rectifier, which can be classified into half-wave rectification and full-wave rectification. It is worth mentioning that in other embodiments, the lighting circuit 152 and the charging circuit 154 can be integrated into a single module. Similarly, in a general lighting state, that is, when the neutral line N is in a conducting state and the antenna 140 detects the presence of the induced electric field, the charging circuit 154 charges the battery module 120 . That is to say, when the power distribution module 150 is in the general lighting state, in addition to providing the power of the mains 20 to the light source 110 , it also provides power to the battery module 120 for charging.
除此之外，当所述电池模块120被充到一第一预定电压(例如3.7伏)后，充电电路154对所述电池模块120进行浮充(floatingcharge)，即以小电流对电池模块120进行充电，以降低功耗。而在电池模块120被充到所述第一预定电压之前，充电电路154对所述电池模块120进行均衡充电(equalization charge)，即以大电流对电池模块120进行充电。In addition, when the battery module 120 is charged to a first predetermined voltage (for example, 3.7 volts), the charging circuit 154 performs floating charge on the battery module 120, that is, charges the battery module 120 with a small current. charging to reduce power consumption. Before the battery module 120 is charged to the first predetermined voltage, the charging circuit 154 performs equalization charge on the battery module 120 , that is, charges the battery module 120 with a large current.
请一并参照图1及图3，图3绘示本发明的优选实施例的电源分配模块的停电延时照明模式的方块示意图。当停电时，即当所述中性线N为导通状态且电源分配模块150无法由所述天线140接收火线L上的感应电场(无交流信号)时，所述电源分配模块150则控制所述电池模块120放电以提供所述灯源110发光所需电力。值得一提的是，电源分配模块150可包括一逻辑判断电路158，用于判断感应电场的接受与否，并用以触发电池模块120的放电。Please refer to FIG. 1 and FIG. 3 together. FIG. 3 is a schematic block diagram of a power failure delay lighting mode of a power distribution module according to a preferred embodiment of the present invention. When there is a power failure, that is, when the neutral line N is in a conducting state and the power distribution module 150 cannot receive the induced electric field (no AC signal) on the live line L by the antenna 140, the power distribution module 150 controls all The battery module 120 is discharged to provide the power required for the light source 110 to emit light. It is worth mentioning that the power distribution module 150 may include a logic judgment circuit 158 for judging whether the induced electric field is accepted or not, and for triggering the discharge of the battery module 120 .
如图3所示，在停电的延时照明状态中，所述电池管理单元156用于侦测所述电池模块120的电压。当侦测所述电池模块120放电至一第二预定电压(例如3伏)时，即控制所述电池模块120停止对所述灯源110供应电力。其中所述第二预定电压小于所述第一预定电压。在此实施例中，上述逻辑判断电路158可整合于所述电池管理单元156中。然而，在其他实施例中，逻辑判断电路158与电池管理单元156可分开设置。As shown in FIG. 3 , the battery management unit 156 is used to detect the voltage of the battery module 120 in the power-off delayed lighting state. When it is detected that the battery module 120 is discharged to a second predetermined voltage (for example, 3 volts), the battery module 120 is controlled to stop supplying power to the light source 110 . Wherein the second predetermined voltage is smaller than the first predetermined voltage. In this embodiment, the above logic judgment circuit 158 can be integrated in the battery management unit 156 . However, in other embodiments, the logic judging circuit 158 and the battery management unit 156 can be set separately.
在停电的延时照明状态中，为了延长照明的时间，所述电池管理单元156可调整所述电池模块120放电的一功率值，所述功率值为所述灯具110的额定功率的一预定百分比。举例来说，所述灯具110的额定功率为10W，电池管理单元156可调整所述电池模块120以百分的五十的功率值，即5W，输出，以延长照明时间。上述调整的百分比可依电池模块120的容量来调整，可借助降低放电的功率值，而可采用较低容量的电池模块120，以降低成本。In the delayed lighting state of power failure, in order to extend the lighting time, the battery management unit 156 can adjust a power value discharged by the battery module 120, and the power value is a predetermined percentage of the rated power of the lamp 110 . For example, the rated power of the lamp 110 is 10W, and the battery management unit 156 can adjust the output of the battery module 120 at a power value of 50%, that is, 5W, to prolong the lighting time. The adjustment percentage can be adjusted according to the capacity of the battery module 120 , and the battery module 120 with a lower capacity can be used by reducing the discharge power value to reduce the cost.
若停电情况结束后，逻辑判断电路158即收到感应电场，则控制由市电20提供额定功率为10W(即100％输出)的电力至灯具110。并由市电20对电池模块120进行充电，如图2所示。If the logic judgment circuit 158 receives the induced electric field after the power outage is over, it controls the mains 20 to provide power with a rated power of 10W (that is, 100% output) to the lamp 110 . And the battery module 120 is charged by the mains 20 , as shown in FIG. 2 .
需注意的是，本实施例的开关130为一切断开关，可由使用者控制灯源110的启闭。也就是说，当使用者打开所述开关130(即导通中性线N)，才具有停电延时照明的功能。若一般无人使用时(灯暗时)，即使发生停电，本实施例的停电延时照明灯具10依然不会发光，藉此节省不必要的电力浪费。It should be noted that the switch 130 in this embodiment is a cut-off switch, which can be controlled by the user to turn on and off the light source 110 . That is to say, when the user turns on the switch 130 (that is, turns on the neutral line N), it has the function of power failure delay lighting. If generally no one is using it (when the light is dark), even if a power failure occurs, the power failure delay lighting fixture 10 of the present embodiment will still not emit light, thereby saving unnecessary power waste.
综上所述，本发明采用低功耗的LED作为灯源110，并配合电源分配模块150分配供给灯源110发光所需的电力。也就是说，当中性线N处于导通时(即打开开关130为一般照明模式)，电源分配模块150提供市电20作为所述灯源110发光的电力。当停电时，电源分配模块150则切换为电池模块120放电，以供给所述灯源110发光的电力。由上可知，本发明的停电延时照明灯具10解决了现有传统紧急照明灯具的笨重且需额外装设的缺点。To sum up, the present invention adopts low-power LED as the light source 110 , and cooperates with the power distribution module 150 to distribute the power required for the light source 110 to emit light. That is to say, when the neutral line N is turned on (that is, the switch 130 is turned on for general lighting mode), the power distribution module 150 provides the commercial power 20 as the power for the light source 110 to emit light. When the power fails, the power distribution module 150 switches to discharge the battery module 120 so as to supply the light source 110 with light emitting power. It can be seen from the above that the power failure delay lighting fixture 10 of the present invention solves the shortcomings of the existing traditional emergency lighting fixtures that are bulky and require additional installation.
虽然本发明以已优选实施例揭露如上，然其并非用以限定本发明。本发明所属技术领域中具有通常知识者，在不脱离本发明的精神和范围内，当可作各种的变更和润饰。因此，本发明的保护范围当视后附的权利要求所界定者为准。Although the present invention has been disclosed above with preferred embodiments, it is not intended to limit the present invention.
