Description

应用于多路负载的供电电源、集成式供电电源及照明灯具 技术领域
本发明涉及照明技术领域，特别是涉及一种应用于多路负载的供电电源、集成式供电电源及照明灯具。
背景技术
灯具内部通常具有多个相同或不同的光源负载(或光源模组)，目前，通常采用至少两个独立电源加上独立于电源的控制模块的方式对灯具进行控制和供电。这种方式使得在组装灯具的电源和控制模块时，不仅需要将光源负载和对应的电源单独连接，还需要将控制模块和对应的电源单独连接，其组装过程和调试过程较为复杂。如果光源负载和电源连接错误，则会出现功率不匹配，从而使光源负载无法点亮，如果控制模块和电源连接错误，则会出现逻辑混乱，从而使光源负载无法点亮。
由此，采用上述连接方式不仅使灯具内部连线复杂混乱，容易出现接错线的情况，而且，由于不同灯具的电源以及光源负载的安装位置不同，因此复杂的连线会导致灯具出现EMI(Electromagnetic Interference，电磁干扰)问题。

具体实施方式
下面将参照附图更详细地描述本公开的示例性实施例。虽然附图中显示了本公开的示例性实施例，然而应当理解，可以以各种形式实现本公开而不应被这里阐述的实施例所限制。相反，提供这些实施例是为了能够更透彻地理解本公开，并且能够将本公开的范围完整的传达给本领域的技术人员。
为解决上述技术问题，本发明实施例提供了一种应用于多路负载的供电电源，该供电电源可以应用在具有多路光源负载的照明系统或者照明灯具中。参见图1，应用于多路负载的供电电源包括第一连接器1、至少一个隔离电源(如图1中示出隔离电源2)、以及与至少一个隔离电源并行的至少一个非隔离电源(如图1中示出的非隔离电源3和非隔离电源4)。其中，第一连接器1与至少一个隔离电源和至少一个非隔离电源电性连接，并用于与控制器(图1中未示出)电性连接，以通过接收来自控制器的电源控制信号实现对至少一个隔离电源及至少一个非隔离电源的供电状态的调节。至少一个隔离电源和至少一个非隔离电源，分别连接相应的负载电路，为负载电路供电，并依据自身的供电状态控制连接的负载电路的工作状态。在该实施例中，至少一个隔离电源、至少一个非隔离电源以及第一连接器1均设置在同一电路板(图1中未示出)上。其中，至少一个隔离电源与至少一个非隔离电源并行指的是，隔离电源和非隔离电源独立工作、互不影响。另外，隔离电源和非隔离电源的数量可以是任意数量，本发明实施例对此不做具体限定。
继续参见图1，在本发明一实施例中，图1中包含了三路负载、两个非隔离电源(即非隔离电源3、4)和一个隔离电源(隔离电源2)，其中A路负载和B路负载分别连接非隔离电源4和非隔离电源3，C路负载连 接隔离电源2，且在隔离电源2和与其连接的C路负载附近形成隔离带，即整个供电电源系统的隔离带位于隔离电源和C路负载附近。
本发明实施例通过将隔离电源和非隔离电源进行一体化设计，即在一个供电电源中同时集成隔离电源和非隔离电源，从而既满足了供电电源的安规要求，又提高了供电电源的整体工作效率。并且，对于具有多路负载的电路，仅需一个供电电源即可完成对多个负载电路的供电和控制，使得负载电路与供电电源的连线更加清楚简洁，不仅方便了电路的组装和调试，还节约了供电电源的组装时间。进一步地，相对于传统的多个负载电路使用多个供电电源的供电方式，本发明实施例大大降低了供电电源的生产成本，节约了资源。
参见图2，在本发明一实施中，应用于多路负载的供电电源还包括控制器11，控制器11与第一连接器(图2中未示出)电性连接，进而实现与隔离电源2、非隔离电源3以及非隔离电源4的连接。控制器11接收来自外界的外部控制信号，并将外部控制信号转换成与各负载电路对应的电源控制信号，将电源控制信号经由第一连接器传送至至少一个隔离电源(如图2中所示的隔离电源2)和/或至少一个非隔离电源(如图2中所示的非隔离电源3、非隔离电源4)，以利用电源控制信号按照预设控制规则控制至少一个隔离电源和/或至少一个非隔离电源的供电状态。
在该实施例中，隔离电源2、非隔离电源3以及非隔离电源4互相独立。例如，控制器11接收外部控制信号后，将外部控制信号转换成三个电源控制信号，并利用这三个电源控制信号分别控制隔离电源2、非隔离电源3以及非隔离电源4的供电状态。
在该实施例中，供电状态可以是隔离电源和/或非隔离电源的开关状态，也可以是隔离电源和/或非隔离电源的输出电流大小，即控制器11可以控制隔离电源和/或非隔离电源的开关状态，也可以对隔离电源和/或非隔离电源的输出电流的大小进行调节。
在本发明一实施例中，控制器11利用电源控制信号按照预设控制规则控制隔离电源和/或非隔离电源的供电状态。其中，该预设控制规则可以是，在控制器11将外部控制信号转换成与各负载电路对应的电源控制信号后，利用电源控制信号的电平性质控制隔离电源和/或非隔离电源的 开关状态，其中，电平性质指电平的高低状态。
例如，参见图2，若电源控制信号为预设开启电平，则控制器11利用该电源控制信号控制隔离电源2和/或非隔离电源3(非隔离电源4)的开关状态为开启状态，进而控制与隔离电源2连接的负载电路C路的工作状态为工作，和/或控制与非隔离电源3(非隔离电源4)连接的负载电路B路(A路)的工作状态为工作。若电源控制信号为预设关闭电平，则控制器11利用该电源控制信号控制隔离电源2和/或非隔离电源3(非隔离电源4)的开关状态为关闭状态，进而控制与隔离电源2连接的负载电路C路的工作状态为停止工作，和/或与非隔离电源3(非隔离电源4)连接的负载电路B路(A路)的工作状态为停止工作。
其中，预设开启电平为提前预设的有效电平值，例如预先定义大于等于5V的电平为有效电平，则预设开启电平的大小为5V。当电源控制信号的电平值大于等于5V时，控制器11控制隔离电源2和/或非隔离电源3(非隔离电源4)的开关状态为开启状态。预设关闭电平为提前预设的无效电平值，例如预先定义小于3V的电平为无效电平，则预设开启电平的大小为3V。当电源控制信号的电平值小于3V时，控制器11控制隔离电源2和/或非隔离电源3(非隔离电源4)的开关状态为关闭状态。
在本发明另一实施例中，控制器11利用电源控制信号按照预设控制规则分别控制隔离电源和/或非隔离电源的供电状态。其中，该预设控制规则还可以是，在控制器11将外部控制信号转换成与各负载电路对应的电源控制信号后，利用电源控制信号的占空比调节非隔离电源和/或非隔离电源的输出电流大小。
例如，参见图2，若电源控制信号占空比产生变化，则控制器11可以利用该电源控制信号，按照预置规则对隔离电源2和/或非隔离电源3(非隔离电源4)的输出电流大小进行调节。其中，预置规则可以是，当电源控制信号的占空比变大，则控制器11调节隔离电源2和/或非隔离电源3(非隔离电源4)的输出电流增大。或者，预置规则还可以是，当电源控制信号的占空比变大，则控制器11调节隔离电源2和/或非隔离电源3(非隔离电源4)的输出电流减小。在实际应用中，供电电源的需求不同其预设规则也会不同，本发明实施例对该实施例提及的预置规则不做具 体限定。
此外，控制器11还可以按照其他的预设控制规则对隔离电源和/或非隔离电源的供电状态进行控制，本发明实施例对此也不做具体的限定。
在本发明一实施例中，控制器11可以设置有第二连接器(图2中未示出)，与外界设备(图2中未示出)电性连接，接收来自外界设备的控制信号，将外界设备的控制信号转换成与各负载电路对应的电源控制信号。例如，控制器11可以利用第二连接器接收来自外界设备通过分控开关发送的开关分控信号，进而控制器11对开关分控信号进行转换，以得到电源控制信号。
在本发明另一实施例中，控制器11设置有无线信号接收器(图2中未示出)，接收来自外界设备的无线控制信号，将外界设备的无线控制信号转换成与各负载电路对应的电源控制信号。例如，控制器11可以利用无线信号接收器接收外界遥控设备发送的无线控制信号，进而由控制器11对无线控制信号进行转换得到电源控制信号。
在本发明一实施例中，控制器11的上设置有控制接口111，控制接口111中设置有第三连接器(图2中未示出)，且第三连接器与供电电源的第一连接器对接，以实现控制器与至少一个隔离电源和至少一个非隔离电源的电性连接。
参见图3所示的第三连接器，第三连接器设置有多个连接端子，图1所示的供电电源上的第一连接器1也设置有相应的连接端子(图1中未示出)。第三连接器的连接端子包括供电端子和接地端子、三个控制端子(即“控制A”、“控制B”和“控制C”三个连接端子，其分别用于将控制器11转换的电源控制信号传输至三个负载电路A、电路B和电路C分别对应的隔离电源或非隔离电源中)、两个信号端子(即“信号1”端子和“信号2”端子，这两个连接端子用于在隔离电源或非隔离电源与控制器之间传输握手信号，该握手信号是一种辅助信号，用于在检测信号时避免产生误检情况)。该实施例中，第三连接器中具有的连接端子个数仅仅是示意性的，本发明实施例对连接端子个数不做具体的限定。
继续参见图2，在本发明一实施例中，供电电源还可以包括PFC(PowerFactor Correction，功率因数校正)电路5和与PFC电路5连接的辅助 电源电路6，其中，PFC电路5用于接收外部电源(图中未示出)的供电，并利用外部电源的供电对辅助电源电路6、隔离电源2、非隔离电源3(非隔离电源4)以及各负载电路进行供电。辅助电源电路6用于接收PFC电路5的供电，并对隔离电源2、非隔离电源3(非隔离电源4)以及控制器11进行供电。其中，隔离电源2、非隔离电源3(非隔离电源4)共用一个PFC电路5和辅助电源电路6。
该实施例中，PFC电路5可以采用BOOST电路，即升压式变换电路。其中，功率因数指的是有效功率除以总耗电量(视在功率)的比值。基本上功率因数可以衡量电力被有效利用的程度，当功率因数值越大，代表其电力利用率越高。功率因数校正是为了提高用电设备功率因数。即本发明实施例中的PFC电路5用于提高隔离电源和非隔离电源的功率因数
在本发明一实施例中，供电电源还可以包括过温保护电路7，该过温保护电路7与辅助电源电路6连接，用于控制辅助电源电路6的供电状态，以避免辅助电源电路6在工作时由于温度过高对隔离电源2、非隔离电源3(非隔离电源4)以及整个电路造成损坏。具体的，当辅助电源电路6的温度超过预设温度时，切断辅助电源电路6对隔离电源2和非隔离电源3(非隔离电源4)的供电，使所辅助电源电路6处于非供电状态。其中，预设温度可以是辅助电源电路6在正常工作时允许的最高温度，预设温度的具体温度值需要根据不同规格的辅助电源电路6确定，本发明实施例对预设温度的具体数值不做限定。
参见图2，为了更加清楚地体现本发明实施例，现对供电电源的供电过程进行具体介绍，其中，图2中的AC交流输入指的是外部电源的供电，例如220V的市电。
当供电电源由外部电源输入上电后，PFC电路5以及辅助电源电路6首先启动，启动完成后，辅助电源电路6为A、B、C三路负载各自对应的电源(非隔离电源4、非隔离电源3、隔离电源2)芯片供电，以及为控制器11供电。PFC电路5为主电路，即隔离电源2、非隔离电源3和非隔离电源4供电，进而各电源分别驱动A、B、C三路负载。其中，该实施例中，负载电路中的负载采用是光源器件或光源模组，当然还可以是其他类型的负载，本发明实施例对此不做具体限定。当负载为光源器件或光源模 组时，利用本发明实施例中的供电电源可以控制光源器件或光源模组的工作状态为工作或者停止工作，也可以调节光源器件或光源模组的输出电流的大小，进而对光源器件或光源模组进行调光、调色以及调功率。如图4所示，通过调节非隔离/隔离电源控制芯片的电流，进而对A路和B路或者对C路的光源器件或光源模组进行调光，通过控制非隔离/隔离电源控制芯片的开关状态(即ON/OFF状态)，进而控制A路和B路或者C路的光源器件或光源模组的工作状态为工作或不工作。
当控制器11收到无线控制信号或者开关分控信号后，将其转换成三个电源控制信号，并经由第一连接器和第三连接器分别传输至隔离电源2、非隔离电源3和非隔离电源4中，以按照预设控制规则控制各路电源的开关状态和/或输出电流大小。A、B、C任意一路负载的输出电流可以跟随电源控制信号占空比的变化实现电流幅度的调整，即调节负载电路输出电流的大小。A、B、C任意一路负载的开关状态也可以由电源控制信号的预设关闭电平和预设开启电平进行控制。例如，C路负载对应的隔离电源2接收到的电源控制信号的占空比变大，则隔离电源2的输出电流增大，从而利用该隔离电源2调节C路负载的输出电流也增大，进而调节了C路负载的光源器件或光源模组的出光效果。又例如，A和B路负载分别对应的非隔离电源4和非隔离电源3接收到的电源控制信号为预设关闭电平，则A和B路负载对应的非隔离电源4和非隔离电源3关闭，进而利用非隔离电源4和非隔离电源3分别控制A和B路负载停止工作。
可见，与传统的在多个负载电路中采用多个电源进行供电的方式相比，本发明实施例的供电电源采用至少一个隔离电源或至少一个非隔离电源集成为多路负载进行供电，各隔离电源或者非隔离电源不仅可以共用一个输入电路，如对外部提供的交流市电进行滤波的滤波电路以及PFC电路等，还可以共用一个辅助电路，如辅助电源电路和过温保护电路，从而大大降低了供电电源的生产成本。此外，当负载采用光源器件时，还可以使多路光源负载在使用一个供电电源的条件下，实现负载电路多种工作状态的组合，如同时调节不同负载电路中的光源器件的出光效果、开关状态等。
基于同一发明构思，本发明实施例还提供了一种集成式供电电源，参见图5，集成式供电电源10包括具有外接接口1011的壳体101、以及应 用于多路负载的供电电源102、电路板103及控制器11。其中，应用于多路负载的供电电源102的至少一个隔离电源(图5中示出一个隔离电源2)和至少一个非隔离电源(图5中示出非隔离电源3和非隔离电源4)均收容于壳体101内部并组装在电路板103上。控制器11电性连接在电路板103上，并配置为可输送电源控制信号至至少一个隔离电源和/或至少一个非隔离电源中，以控制至少一个隔离电源和/或至少一个非隔离电源的供电状态。
在本发明一实施例中，控制器11可以设置在壳体101外部，图5所示实施例为控制器11设置在壳体101外部的情况。电路板103上设置有第一连接器(图5中未示出)，并与至少一个隔离电源和至少一个非隔离电源电性连接。相应的，控制器11上设置有与第一连接器对应的第三连接器(图5中未示出)，且第三连接器和第一连接器对接，以实现控制器11和至少一个隔离电源和至少一个非隔离电源的电性连接。
在本发明另一实施例中，控制器11还可以设置在壳体101内部，控制器11集成在电路板103上，且收容于壳体101内部，并通过电路板103实现与至少一个隔离电源和至少一个非隔离电源的电性连接。
在该实施例中，壳体101为L形，因此形成有缺口1014。控制器11体积较小，可以填充在该缺口1014中，并与集成式供电电源10插接。
下文实施例以集成式供电电源10包括一个隔离电源2和两个非隔离电源(即非隔离电源3和非隔离电源4)为例进行说明。
继续参见图5，在本发明一实施例中，由于壳体101是L形的，因此壳体101可以包括有L形状的壳体顶盖1012和L形状的壳体底盖1013，外接接口1011设置在壳体顶盖1012的缺口1014位置处，第一连接器与电路板103电性连接后，可以置于壳体顶盖1012的外接接口1011位置处。控制器11上设置的第三连接器与置于外接接口1011中的第一连接器插接。并且，壳体顶盖1012和壳体底盖1013互相扣合从而将隔离电源2、非隔离电源3和非隔离电源4容纳在壳体101内部。
在本发明一实施例中，控制器11的第三连接器与电路板103的第一连接器除了插接之外，还可以通过线缆连接。其中，线缆包含导线和分别设置于导线两端的两个连接器，以将隔离电源2(或非隔离电源3，或非 隔离电源4)与控制器11连接。
参见图5，在本发明一实施例中，控制器11可以设置有用于连接天线的无线信号接收器110，接收来自外界设备的无线控制信号，将外界设备的无线控制信号转换成与各负载电路对应的电源控制信号。例如，控制器11可以利用无线信号接收器110接收外界遥控设备(图5中未示出)发送的无线控制信号，进而由控制器11对无线控制信号进行转换得到电源控制信号。
此外，PTC电路5也容纳于壳体101内部，并且，上文实施例提及的应用于多路负载的供电电源中包含的其他电路，如过温保护电路(图5中未示出)、辅助电源电路(图5中未示出)等也可以收容于壳体101内部，以方便各电路之间的布线连接。
在本发明实施例中，当需要对多路负载进行供电时，仅需一个集成式供电电源即可以实现对多路负载的供电。控制器的信号接收接口接收外部控制信号后，进一步可以对负载电路进行控制、调节。若负载电路中的负载为光源器件，则可以控制光源器件的开启或关闭状态、颜色的深浅以及亮度的明暗状态等。
基于同一发明构思，本发明实施例还提供了一种照明灯具，包括多个光源器件或多个光源模组，以及上文任一实施例中提及的集成式供电电源，该供电电源与多个光源器件或多个光源模组分别连接，能够对多个光源器件或者多个光源模组进行供电，以及分别控制多个光源器件或多个光源模组工作状态。
其中，多个光源器件或多个光源模组工作状态包括多个光源器件或多个光源模组的开启或关闭状态、颜色的深浅以及亮度的明暗状态等。
本发明实施例中，照明灯具虽然包含了多路光源负载，但是仅仅采用了一个供电电源，通过调节该供电电源的状态，可以使照明灯具达到多种出光效果，节约了供电电源的成本，进而节约了照明灯具的生产成本。
至此，本领域技术人员应认识到，虽然本文已详尽示出和描述了本发明的多个示例性实施例，但是，在不脱离本发明精神和范围的情况下，仍可根据本发明公开的内容直接确定或推导出符合本发明原理的许多其他变型或修改。因此，本发明的范围应被理解和认定为覆盖了所有这些其他 变型或修改。
