具体实施方式Detailed ways
下面结合附图及实施例对本发明进行详细说明。The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
参见图1及图2所示，是本发明具有紧急照明功能的多媒体显示器的第一较佳实施例，该多媒体显示器1主要包括一无线讯号侦测器11，一与无线讯号侦测器11电耦接的主控制器(亦是一讯号处理器)12，一与主控制器12电耦接的显示器13，一提供一电力讯号给主控制器12及显示器13的电源供应器14，一与电源供应器14电耦接，以接受电源供应器14的电力讯号充电的可充电电池模块15，以及一与主控制器12及可充电电池模块15电耦接的紧急照明单元16。Referring to Fig. 1 and shown in Fig. 2, be the first preferred embodiment of the multimedia display with emergency lighting function of the present invention, this multimedia display 1 mainly comprises a wireless signal detector 11, one and wireless signal detector 11 electric A coupled main controller (also a signal processor) 12, a display 13 electrically coupled with the main controller 12, a power supply 14 that provides a power signal to the main controller 12 and the display 13, and a power supply 14 with the main controller 12 and the display 13. The power supply 14 is electrically coupled to the rechargeable battery module 15 charged by receiving the power signal of the power supply 14 , and an emergency lighting unit 16 is electrically coupled to the main controller 12 and the rechargeable battery module 15 .
其中无线讯号侦测器11，例如一红外线讯号侦测器，是用以侦测来自一遥控器2的一遥控讯号，例如红外线遥控讯号，并传送给主控制器12，主控制器12根据该遥控讯号，输出相对应的一影音频号至显示器13显示。电源供应器14将由外界输入的一交流电源AC转换成一直流的电力讯号，并供电给主控制器12及显示器13。此外，电源供应器14还输出电力讯号对可充电电池模块15充电，使可充电电池模块15储存电力。Wherein the wireless signal detector 11, such as an infrared signal detector, is used to detect a remote control signal from a remote controller 2, such as an infrared remote control signal, and transmits to the main controller 12, the main controller 12 according to the The remote control signal outputs a corresponding video and audio signal to the display 13 for display. The power supply 14 converts an AC power input from the outside into a DC power signal, and supplies power to the main controller 12 and the display 13 . In addition, the power supply 14 also outputs a power signal to charge the rechargeable battery module 15 so that the rechargeable battery module 15 stores power.
借此，当发生停电状况，导致输入电源供应器14的交流电源AC中断，电源供应器14停止输出电力讯号给可充电电池模块15时，可充电电池模块15即会同时输出电力给主控制器12及紧急照明单元16，让主控制器12仍然能供电给无线讯号侦测器11，以接收经无线讯号侦测器11传来的遥控讯号。In this way, when a power failure occurs, causing the AC power input to the power supply 14 to be interrupted, and the power supply 14 stops outputting power signals to the rechargeable battery module 15, the rechargeable battery module 15 will simultaneously output power to the main controller. 12 and the emergency lighting unit 16, so that the main controller 12 can still supply power to the wireless signal detector 11 to receive the remote control signal sent by the wireless signal detector 11.
此时，若遥控器2上的一紧急照明按键21被用户按下(触发)，遥控器2会发送一代表紧急照明的遥控讯号给无线讯号侦测器11，当主控制器12收到由无线讯号侦测器11传来的代表紧急照明的遥控讯号时，就会产生一紧急照明讯号控制紧急照明单元16启动紧急照明，而达到本发明的目的。At this time, if an emergency lighting button 21 on the remote controller 2 is pressed (triggered) by the user, the remote controller 2 will send a remote control signal representing emergency lighting to the wireless signal detector 11.

Between the power supply 14 and the rechargeable battery 152 , the electric power signal input by the power supply 14 is received, and a charging current is output to charge the rechargeable battery 152 .
且为了避免可充电电池152过度充电，在充电电路151与可充电电池152之间还设有一过电压保护电路153，其在可充电电池152充电达到一额定电压，例如3.6伏特时，即禁止充电电路151继续对可充电电池152充电，以保护可充电电池152不致因过度充电而损坏。And in order to prevent the rechargeable battery 152 from being overcharged, an overvoltage protection circuit 153 is also provided between the charging circuit 151 and the rechargeable battery 152, which prohibits charging when the rechargeable battery 152 is charged to a rated voltage, such as 3.6 volts. The circuit 151 continues to charge the rechargeable battery 152 to protect the rechargeable battery 152 from being damaged due to overcharging.
且在本实施例中，紧急照明单元16包含两个串联的发光二极管161，以及一电耦接在可充电电池152与该二发光二极管161之间，并受主控制器12控制的开关电路162。当输入充电电路151的电力讯号消失，且主控制器12输出紧急照明讯号至紧急照明单元16时，紧急照明讯号控制开关电路162导通可充电电池152及该二发光二极管161，使可充电电池152对该二发光二极管161输出电力，而点亮该二发光二极管161。And in this embodiment, the emergency lighting unit 16 includes two LEDs 161 connected in series, and a switch circuit 162 electrically coupled between the rechargeable battery 152 and the two LEDs 161 and controlled by the main controller 12 . When the power signal input to the charging circuit 151 disappears, and the main controller 12 outputs an emergency lighting signal to the emergency lighting unit 16, the emergency lighting signal control switch circuit 162 turns on the rechargeable battery 152 and the two light-emitting diodes 161, so that the rechargeable battery 152 outputs power to the two LEDs 161 to light the two LEDs 161 .
此外，为了避免可充电电池152因过度放电而造成永久损坏，本实施例在可充电电池152与紧急照明单元16之间还设有一电池保护电路154，其侦测可充电电池152的电压低于一默认值，例如2.8伏特时，即禁止可充电电池152输出电力，以避免可充电电池152过度放电。In addition, in order to prevent the rechargeable battery 152 from being permanently damaged due to excessive discharge, a battery protection circuit 154 is provided between the rechargeable battery 152 and the emergency lighting unit 16 in this embodiment, which detects that the voltage of the rechargeable battery 152 is lower than A default value, such as 2.8 volts, prohibits the rechargeable battery 152 from outputting power to avoid excessive discharge of the rechargeable battery 152 .
另外，本实施例在充电电路151与电源供应器14之间还设有一手动开关155，使用者可借由拨动该手动开关155以控制该电源供应器14与充电电路151的电耦接与否，连带控制该电源供应器14的电力讯号是否输入该充电电路151，从而开启或关闭多媒体显示器1的紧急照明功能。In addition, in this embodiment, a manual switch 155 is provided between the charging circuit 151 and the power supply 14, and the user can control the electrical coupling and connection between the power supply 14 and the charging circuit 151 by flipping the manual switch 155. No, jointly control whether the power signal of the power supply 14 is input to the charging circuit 151 , so as to turn on or turn off the emergency lighting function of the multimedia display 1 .
再参见图4所示，是本发明具有紧急照明功能的多媒体显示器的第二较佳实施例，多媒体显示器3同样包含一无线讯号侦测器11，一与无线讯号侦测器11电耦接的主控制器12，一与主控制器12电耦接的显示器13，一提供一电力讯号给主控制器12及显示器13的电源供应器14，一与电源供应器14电耦接，以接受电源供应器14的电力讯号充电的可充电电池模块15，以及一与可充电电池模块15电耦接的紧急照明单元16外，本实施例与第一实施例不同处在于：本实施例的多媒体显示器3还包含一与无线讯号侦测器11、可充电电池模块15及紧急照明单元16电耦接的讯号处理器17。Referring again to shown in Figure 4, it is the second preferred embodiment of the multimedia display with emergency lighting function of the present invention, the multimedia display 3 also includes a wireless signal detector 11, one electrically coupled with the wireless signal detector 11 Main controller 12, a display 13 electrically coupled to the main controller 12, a power supply 14 that provides a power signal to the main controller 12 and the display 13, and a power supply 14 electrically coupled to receive power The rechargeable battery module 15 charged by the power signal of the supplier 14, and an emergency lighting unit 16 electrically coupled with the rechargeable battery module 15, the difference between this embodiment and the first embodiment lies in: the multimedia display of this embodiment 3 also includes a signal processor 17 electrically coupled with the wireless signal detector 11, the rechargeable battery module 15 and the emergency lighting unit 16.
当由外界输入的交流电源AC正常供电给电源供应器14时，电源供应器14负责供电给主控制器12，使控制多媒体显示器3的影音输出功能可以正常运作，电源供应器14还同时对可充电电池模块15充电使储备电力。借此，当外界输入的交流电源AC突然中断时，可充电电池模块15会立即输出电力给紧急照明单元16及讯号处理器17，以由讯号处理器17提供电力给无线讯号侦测器11，并接收来自无线讯号侦测器11的无线讯号。When the alternating current power supply AC input by the outside supplies power to the power supply 14 normally, the power supply 14 is responsible for supplying power to the main controller 12, so that the audio-visual output function of the control multimedia display 3 can operate normally, and the power supply 14 can also provide power to the main controller 12 at the same time. The rechargeable battery module 15 is charged to reserve power. In this way, when the AC power input from the outside is suddenly interrupted, the rechargeable battery module 15 will immediately output power to the emergency lighting unit 16 and the signal processor 17, so that the signal processor 17 provides power to the wireless signal detector 11, And receive the wireless signal from the wireless signal detector 11.
因此，当遥控器2发射一代表紧急照明的遥控讯号给无线讯号侦测器11，且讯号处理器17收到无线讯号侦测器11传来的代表紧急照明的遥控讯号时，就会产生一紧急照明讯号控制紧急照明单元16启动紧急照明，而达到本发明的目的。Therefore, when the remote controller 2 transmits a remote control signal representing emergency lighting to the wireless signal detector 11, and the signal processor 17 receives the remote control signal representing emergency lighting from the wireless signal detector 11, a The emergency lighting signal controls the emergency lighting unit 16 to start the emergency lighting, so as to achieve the purpose of the present invention.
