Description

照明系统及其相位信号传送装置 技术领域
本发明是与灯具控制有关；特别是指一种照明系统及其相位信号传送装置。
背景技术
按，一般建筑物的室内配线方式是在天花板上的电气盒与壁面上的电气盒之间预留两条供连接开关的电线。在安装电器设备(如灯具或电扇)时，将电器设备装设于天花板上，且将市电的其中一端连接于电器设备，市电的另一端通过预留的电线串接一个开关，再接回该电器设备上，以形成一个电源回路。通过切换该开关，即可控制电器设备的启闭。
随着科技的进步，电器设备的功能愈来愈多，以发光二极管照明系统为例，现今的发光二极管照明系统除了单纯的控制启闭外，更具备有调整亮度、色度的功能，因此，除了原本的电源回路外，也必须要有额外的控制线路才能将控制信号由壁面上的控制面板传送到装设于天花板上的发光二极管模块。
因此，要装设具备有亮度、色度的调整功能的发光二极管照明系统时，则必须另外再配接控制线路，利用控制线路传送控制信号，以控制照明系统的发光二极管模块。然，额外配接控制线路，将会使得房屋的修缮及装潢施工成本增加。
另有二种方式可在不额外配接控制线路的情况下传送控制信号，其一为无线传输，其二为载波传输。无线传输方式是在发光二极管模块及壁面的控制面板分别加装无线接收器与发射器，以无线传输的方式传送控制信号控制发光二极管模块。载波传输方式是利用调压器将控制信号调变成调频信号或调幅信号，利用电力线载波，再以解调器还成原来的控制信号后控制发光二极管模块。
然，前述两种方式的设备成本昂贵，且在建筑物壁面的发射器及调压器均须另外配接电源线外，配接电源线亦是额外的困扰。再者，无线或载波所传输的信号易受其它无线信号干扰，要通过各国EMI和EMS安规更是徒增困扰。

实现发明的最佳方式
为能更清楚地说明本发明，兹举下列实施例并配合图示详细说明如后。图1所示为本发明第一较佳实施例的照明系统1，包含有以发光二极管模块10为例的灯具、输入接口12、相位信号传送装置14。
该发光二极管模块10具有多个发光二极管，用以接收电信号以产生亮光提供照明。该输入接口12包含有开关122，该开关122为常开式的按压开关，该开关122在使用者按压时呈短路状态(即本发明定义的第一状态)。
该相位信号传送装置14包含有相角控制模块16与驱动模块18。其中：
该相角控制模块16电性连接交流电源S与该开关122，该相角控制模块16用以侦测该开关122的状态，并在该开关122受按压而导通时，该相角控制模块16改变该交流电源S的波形，使该交流电源S的波形的正半波周期产生延迟导通角后输出；而在该开关122未为受按压时，该开关122则自动复归呈开路状态(即本发明定义的第二状态)，且该相角控制模块16不改变该交流电源S的波形，亦即该相角控制模块16所输出的波形中无该延迟导通角存在。而该延迟导通角的角度以小于或等于90度为佳，以减少该交流电源的谐波及减少功率因子降低的程度。
请参阅图2A，本实施例中，在该开关122受压时(如图2A的波形1)，该相角控制模块16改变该交流电源S的波形，在其输出的电压波形的正半波周期的后缘产生产生延迟导通角(如图2A的波形2)。在实务上，可设计成如图2B所示于正半波周期的 前缘产生延迟导通角。当然，亦可在负半波前或后缘，抑或是在正半波及负半波周期的前缘或后缘产生延迟导通角，同样都可以达到作为开关122被按下的识别。
该驱动模块18包含有相互电性连接的电源转换电路182与控制单元184。其中，该电源转换电路182电性连接该相角控制模块16及该发光二极管模块10，用以接收该相角控制模块16所输出的电能，并转换成该发光二极管模块10所需的电能，该电源转换电路182是可受控制地改变该发光二极管模块10的开、关状态及亮度。在本实施例中，该电源转换电路182是以脉冲宽度调变(Pulse Width Modulation，PWM)电路为基础进行设计，并通过脉冲宽度调变的方式来调整供予该发光二极管模块10的电信号的频率宽度。当然在实际实施上，该电源转换电路182亦可为调整电信号大小或其他调整电信号的电路设计。
该控制单元184包含有相角侦测电路184a与处理器184b。该相角侦测电路184a电性连接该相角控制模块16，用以侦测该相角控制模块16输出的电能的波形中是否具有该延迟导通角以及侦测该延迟导通角的角度，并将侦测结果传递予该处理器184b。该处理器184b内建有多种控制模式，所述控制模式包括全亮照明模式、默认照明模式与亮度调整模式，并以其中一种控制模式控制该电源转换电路182输出的电信号，借以驱动该发光二极管模块10产生亮光，并利用该相角侦测电路184a所侦测该延迟导通角的结果判断该开关122的状态，以做为控制模式切换的依据。其中：
该全亮照明模式是控制该电源转换电路182驱动该发光二极管模块10产生额定功率下最大亮度值的亮光。
该默认照明模式是控制该电源转换电路182驱动该发光二极管模块10产生默认亮度值的亮光，在本实施例中，该预设亮度值初始设定为最大亮度值的一半，而在亮度调整模式中是可更新该预设亮度值。
该亮度调整模式是控制该电源转换电路182驱动该发光二极管模块10产生的亮光反复于第一亮度值与第二亮度值之间变化，直到该处理器184b判断该开关122的状态改变时，停止控制亮度的变化，并记录该发光二极管模块10当下所产生的亮光的亮度值，且将记录的亮度值取代该默认照明模式原先的默认亮度值，并驱动该发光二极管模块10产生具有新的预设亮度值的亮光。在本实施例中，该第一亮度值为最大亮度值，该第二亮度值为最小亮度值，借此，在亮度调整模式时，该发光二极管模块10的亮光即在最大亮度与最小亮度之间变化。实务上，该处理器184b亦可控制该电源转换电路182驱动该发光二极管模块10产生的亮光由介于该第一、第二亮度值之间的第三亮度值开始增加或减少，而反复于第一亮度值与第二亮度值之间变化。该第三亮度值可设定为最大亮度值的二分之一，借此切换至该亮度调整模式时，先以居中的亮度发光，避免使用者因亮度变化太大而感到眼睛不适。
由于该开关122被按压的期间，该相角控制模块16输出的电能的波形中每一个周期皆会有该延迟导通角存在，因此该处理器184b可依据具有该延迟导通角的周期数计算该开关122被压下的时间长度，据以进行控制模式切换。
在初始状态(交流电源S刚接通时)且该开关122未按压前，该相角控制模块16未改变该交流电源S的波形，该相角侦测电路184a所侦测的波形未具有该延迟导通角，此时，该处理器184b控制该电源转换电路182阻断供予该发光二极管模块10的电能，使该发光二极管模块10为熄灭的状态。
在该开关122按压后，该相角侦测电路184a侦测到该相角控制模块16输出的电能的波形中具有该延迟导通角，而该处理器184b判断该开关122被按压的按压时间，并进行相对应的控制。
在该按压时间小于预定时间(本实施例中设为1.2秒)时，该处理器184b切换至该全亮照明模式，使该发光二极管模块10产生具有最大亮度值的亮光。
再按压一次该开关122后，且按压时间小于该预定时间，该处理器184b切换至该默认照明模式，使该发光二极管模块发出具有该默认亮度值的亮光。
再按压一次该开关122后，且按压时间小于该预定时间，该处理器184b控制该电源转换电路182阻断供予该发光二极管模块10的电能，使该发光二极管模块10为熄灭的状态。
当使用者需要改变该预设亮度值时，按压该开关122超过该预定时间，该处理器184b即切换至该亮度调整模式，以供用户改变设定的预设亮度值。
借由上述的结构，该照明系统1应用于建筑物时，可将该开关122及该相角控制模块16装设于建筑物的壁面上(即装设于控制端)，而将该驱动模块18及该发光二极管模块10装设于建筑物的壁面或天花板(即装设于负载端)。如此，该相角控制模块16与该驱动模块18之间只需用两条连接交流电源S的电线连接，换言之，利用建筑物原有的配线即可传输对应该开关122状态的波形至该驱动模块18，而该驱动模块18即可判断该开关122的状态，并送出对应的电信号控制该发光二极管模块10。
前述的装设方式仅是应用例而已，并不以此为限，可依实际的需求调整各构件装设的位置。
在实务上，该发光二极管模块10可包含有多个以第一发光二极管为例的第一光源及多个以第二发光二极管为例的第二光源，且所述第一发光二极管的光色不同于所述该第二发光二极管的光色。举例而言，所述第一发光二极管的光色为冷光色系(如白光、蓝光等)，而所述第二发光二极管的光色为暖光色系(如黄光、红光等)。
该驱动模块18的电源转换电路182则可个别控制所述第一发光二极管及所述第二发光二极管的亮度比例，而所述的亮度比例是指该第一、第二发光二极管所产生的亮光的亮度值占该最大亮度值或该预设亮度值的比例，利用所述第一发光二极管与第二发光二极管的亮度比例的搭配，可达到调整该发光二极管模块10产生的亮光的色温。
该处理器184b的控制模式中，该全亮照明模式包括有第一亮度比例信息，该第一亮度比例信息是记录该全亮照明模式时，所述第一、第二发光二极管的亮度比例。该默认照明模式包括有第二亮度比例信息，该第二亮度比例信息是记录该默认照明模式时，所述第一、第二发光二极管的亮度比例。
该处理器184b的控制模式更包含有色度调整模式，供调整该第一比例信息或第二比例信息。当该处理器184b操作于该全亮照明模式或该默认照明模式时，用户持续按压该开开关122超过另一个设定时间(本实施例中为4秒)，该处理器的操作模式则切换至该色度调整模式。其中：
该色度调整模式是控制该电源转换电路182驱动该发光二极管模块10产生亮光，并在亮度值(即最大亮度值或预设亮度值)不变的情况下，反复地改变该发光二极管模块10的所述第一发光二极管以及所述第二发光二极管的亮度比例，直到该处理器184b判断该开关122的状态改变时，停止控制所述第一、第二发光二极管亮度比例的变化， 并记录该当下该第一、第二发光二极管的亮度比例，且将记录的亮度比例取代该全亮照明模式原先的第一亮度比例信息或取代该默认照明模式原先的第二亮度比例信息，并驱动所述第一、第二发光二极管产生具有新的亮度比例的亮光。
借此，使用者仅需通过该开关122按压时间的长短即可进行亮度的切换，以及调整亮度或调整色度的选择。
以下再提供其它较佳可行的实施例，同样具有相同上述的效果。
图3所示为本发明第二较佳实施例的照明系统2，其是以上述第一实施例的结构为基础，更增设切换开关20，分别电性连接该交流电源S与该相角控制模块16。该切换开关20供开启及关闭该发光二极管模块10的亮光。
在本实施例中，该切换开关20导通时，该驱动模块18的处理器184b操作于该全亮照明模式，使该发光二极管模块10的亮光为最亮。同样地，通过按压该开关122的按压时间长短，即可在该默认照明模式、该全亮照明模式之间切换，而且同样可切换至该亮度调整模式或该色度调整模式。
图4所示为本发明第三较佳实施例的照明系统3，其是以上述第二实施例的结构为基础，不同的是本实施例的输入接口22包含有二个开关222，224，该二个开关222，224电性连接该相角控制模块16。各该开关222，224被按压而呈短路状态时，该相角控制模块16使该交流电源S的波形的正半波周期产生该延迟导通角后输出，且按压各该开关222，224所产生的该延迟导通角的角度各不相同。借此，该处理器184b即可利用该相角侦测电路184a所侦测的该延迟导通角的角度对应所述开关222，224的按压状态，以进行在所述控制模式之间切换。
举例而言，利用短按该开关222(即按压时间小于该设定时间)作为该全亮照明模式与该默认照明模式之间的切换；长按该开关222(即按压时间大于该设定时间)，则切换至该亮度调整模式。
而该处理器184b更可内建多个预设色度，各该预设色度是对应一种所述第一、第二发光二极管的亮度比例。在该全亮照明模式或该默认照明模式时，利用短按该开关224，以切换其中该预设色度，并将该预设色度取代原先储存的第一亮度比例信息或第二亮度比例信息，并驱动所述第一、第二发光二极管产生具有新的亮度比例的亮光。
此外，在该全亮照明模式或该默认照明模式时，利用长按该开关224，则切换至该色度调整模式，以进行该发光二极管模块10的色度调整。
图5所示为本发明第四较佳实施例的照明系统4，其具有大致相同于上述第二实施例的结构，不同的是，本实施例的输入接口24包含有三个开关242，244，246，该三个开关242，244，246电性连接该相角控制模块16。按压各该开关242，244，246时，该相角控制模块16则产生对应各该开关242，244，246的特定角度的该延迟导通角。此外，本实施例的照明系统4包含有三组驱动模块262，264，266，及发光二极管模块282，284，286，每一该驱动模块262，264，266是对应判断一个特定角度的该延迟导通角，借此，各该驱动模块262，264，266即可对应侦测各该开关242，244，246的按压状态，进而控制各该发光二极管模块282，284，286。
举例而言，该开关242被按压时，该驱动模块262侦测到相对应的该延迟导通角的角度并计算按压时间，以对该发光二极管模块282进行控制。
当然，本实施例输入接口24的开关的数量不以三个为限，亦可设置三个上以，且 在负载端相对应地设置相同数量的驱动模块及发光二极管模块，同样可以达到在控制端操控多组发光二极管模块的目的。
此外，为配合建筑物的格局，上述第一实施例的照明系统亦可设计成如图6所示的连接方式，并将二组该相角控制模块16及该开关122设于建筑物中的不同位置，借此，用户即可在不同的位置控制发光二极管模块10。依据相同的构思，第二、第三、第四实施例的照明系统亦可分别设计成如图7至图9所示的连接方式，将二组三路开关29、该相角控制模块16及输入接口12，22，24设于建筑物中的不同位置，用户即可在不同的位置控制发光二极管模块。
图10所示为本发明第五较佳实施例的照明系统5，包含有切换开关30、输入接口32、相角控制模块34、驱动模块36与发光二极管模块38。该输入接口32包含有可变电阻322，且该相角控制模块34电性连接该可变电阻322，并依据该可变电阻322的电阻值，产生对应该可变电阻322电阻值的角度的该延迟导通角。本实施例中，该可变电阻322的电阻值愈大，对应该延迟导通角的角度则愈大；反之，电阻值愈小则该延迟导通角的角度愈小，即使该可变电阻322的电阻值调整到0欧姆，该延迟导通角的角度大于零度，亦即该相角控制模块34输出的电能的波形中仍有该延迟导通角存在。
而该驱动模块36的处理器362则依据相角侦测电路364所侦测的该延迟导通角的角度，计算该可变电阻322的电阻值。并利用电阻值的变化相对应的控制电源转换电路366输出对应的电信号至该发光二极管模块38，以进行控制。例如，可利用电阻值的变化调整该发光二极管模块38的亮度，或是调整该发光二极管模块38的色度。
图11所示为本发明第六较佳实施例的照明系统6，其具有大致相同于第二实施例的结构，包含有多组驱动模块40及发光二极管模块42。各该驱动样组包括相角侦测电路402、处理器404与电源转换电路406。各组驱动模块40及发光二极管模块42是装设于不同的位置。使用者可使用该切换开关20同时控制所述驱动模块40点亮或熄灭各自连接的发光二极管模块42；按压该开关122且依据按压时间及次数，同时控制各该驱动模块40的处理器404在不同控制模式之间的切换，如全亮照明模式、默认照明模式、亮度调整模式。
在亮度调整模式时，各该驱动模块40的处理器404是各自控制所连接的电源转换电路406驱动发光二极管模块产生的亮光反复于第一亮度值与第二亮度值之间变化，直到各该处理器404判断该开关122的状态改变时，停止控制亮度的变化，并记录各该发光二极管模块42当下所产生的亮光的亮度值，取代各该处理器404中该默认照明模式原先的默认亮度值。
在实际使用上，所述处理器404可能因为处理器404本身的制程差异、温度变化、电压不稳及其他噪声的干扰，造成其输出信号产生时序上的偏移而产生计时的误差。如此，将造成在亮度调整模式时，所述处理器404各自控制发光二极管模块42亮度改变的时间点有所误差。所述发光二极管模块42产生的亮光反复变化的时间愈长或次数愈多，所述发光二极管模块42之间的亮度差异愈明显，使得该开关122的状态改变时每一该处理器404记录的当下亮度值皆不相同，造成所述发光二极管模块42产生不同默认亮度值的亮光。
为避免上述的情形，本实施例在亮度调整模式时，更增加同步的机制，以使所述处理器404可在同一个时间点同步地控制各自连接的电源转换电路406。利用各该相角侦 测电路402侦测该相角控制模块16输出的电能的波形，各该处理器404即可相对取得该交流电源S的周期，由该交流电源S周期中取基准点作为同步之用，本实施例是以每一个周期中的第一个零交越点(zero crossing)作为该基准点。各该处理器404每次测得该基准点时，即控制该电源转换电路406驱动该发光二极管模块42产生的亮光增加或减少亮度差值。
举例而言，该第一亮度值为″100″，该第二亮度值为″10″，该亮度差值为″1″；在切换至亮度调整模式后，各该处理器404在交流电源S周期的第一个零交越点时，控制各该电源转换电路406驱动发光二极管模块42产生的亮度值为″100″；在之后的每一个周期的第一个零交越点时，减少一个亮度差值″1″，直到亮度值为″10″，再由亮度值″10″开始增加，每一次交流电源S周期增加一个亮度差值″1″，直到增加到亮度值为″100″再进行下一次的循环，如此重复地在第一亮度值与第二亮度值之间变化。
借此，通过该交流电源S波形作为同步的依据，可确保所有的处理器404每次皆在同一个时间点改变亮度值，有效地使所述发光二极管模块42的亮度变化一致，避免各个处理器404分别进行发光二极管模块42亮度控制时发生各个发光二极管模块42亮度不一致的情形。在实务上亦可以在交流电源S的每一个周期中取二个零交越点作为同步的基准点，当然亦可以波形中的峰值作为基准点，同样可以达到同步的效果。
在实务上，各该发光二极管模块42包含有多个第一发光二极管及多个第二发光二极管，且第一发光二极管的光色不同于第二发光二极管的光色。各该处理器404的控制模式更包含有色度调整模式，以供调整各该发光二极管模块42的色度。在各该处理器404操作于该色度调整模式，同样可利用该交流电源S的波形作为同步的依据，亦即，各该处理器404在每一个周期中的基准点改变各该发光二极管模块42的所述第一发光二极管以及所述第二发光二极管的亮度比例，如此，即可让各该发光二极管模块42在同一个时间点同步地改变色度，避免所述发光二极管模块42的色度产生差异。
在上述各实施例中，是以发光二极管模块为例说明本发明的照明系统及相位信号传送装置，本发明的照明系统除了采用发光二极管模块之外，亦可采用其它类型的灯具，例如荧光灯、气体发电灯，对于不同类型的灯具仅需采用相对应的电源转换电路即可驱动灯具。
据上所述，本发明利用相角控制模块与驱动模块构成的相位信号传送装置，将输入接口的状态通过电源波形的延迟导通角，由控制端传送到负载端，以输出对应输入接口状态的电信号控制灯具，亦即利用交流电源的波形传送信号。相比于传统的信号传输方式，本发明无需增加额外的配线或是以无线信号传输装置传输信号，有效减少安装照明系统的成本。
以上所述，仅是本发明的较佳实施例而已，并非对本发明做任何形式上的限制，虽然本发明已以较佳实施例揭露如上，然而并非用以限定本发明，任何熟悉本专业的技术人员，在不脱离本发明技术方案范围内，当可利用上述揭示的技术内容做出些许更动或修饰为等同变化的等效实施例，但凡是未脱离本发明技术方案的内容，依据本发明的技术实质对以上实施例所做的任何简单修改、等同变化与修饰，均仍属于本发明技术方案的范围内。
