在本实施例中，支持灯光控制的手机壳包括：手机保护壳体1、通信组件、整流电路单元105、MCU（Microcontroller Unit，微控制单元）101以及发光单元103，通信组件包括NFC单元102，手机保护壳体1用于容置并保护手机2，NFC（Near Field Communication，近场通信）单元102、整流电路单元105、MCU101设置在手机保护壳体1上；NFC单元102与整流电路单元105连接，NFC单元102收集手机2发出的射频信号，将射频信号转换为电流发送给整流电路单元105；MCU101分别与NFC单元102、整流电路单元105、发光单元103连接，MCU101通过NFC单元102、整流电路单元105获取电流，并通过通信组件与手机2通信连接，获取手机2传输的指令，并根据指令控制发光单元103的显示状态。
本实施例的支持灯光控制的手机壳通过NFC单元102将智能终端发出的射频信号转换为电流来实现对支持灯光控制的手机壳的MCU101和其它元件供电，如向发光单元103供电。同时NFC单元102可作为通信单元与智能终端通信连接，MCU101通过NFC单元102接收智能终端发送的灯光控制指令，根据该灯光控制指令，控制发光单元103的发光状态。
在本实施例中，通信组件还包括蓝牙单元，MCU101与蓝牙单元连接，并通过蓝牙单元与手机2建立通信连接，利用蓝牙实现手机2与手机壳之间的信息传输。MCU101与蓝牙单元获取整流电路单元105输入的电流后，可通过OOB（OUT OF BAND）NFC方式完成蓝牙单元与智能终端的快速配对。
在其他实施例中，通信组件也可以包括红外线、WiFi以及其他能够与手机通信的器件。
在本实施例中，智能终端发出的射频信号指NFC单元通讯时所使用的13.56MHZ射频信号。
在本实施例中，手机2为具有NFC器件，并能够与该支持灯光控制的手机壳连接的设备。
在本实施例中，手机保护壳体1用于保护手机2，避免直接受到碰撞或刮擦，或用于装饰或增加手感等用途，通常手机保护壳体1将手机2主体（非正面）完全容纳或部分容纳于其中。
在本实施例中，由于手机2在未感应到NFC 标签时，出于节能考虑通常默认发出的射频信号频率或强度不足，此时，NFC单元102转换的电信号功率过低，可能不能用于激活或供给MCU101以及发光单元103使用。
因此，在一个优选的实施例中，NFC单元102包括维持电路，维持电路包括线圈和NFC标签，在手机2与支持灯光控制的手机壳接触时，使手机2感应到维持电路的NFC标签，从而触发手机2发出稳定且功率足够的射频信号以获取能够供支持灯光控制的手机壳使用的电流。
在本实施例中，维持电路是NFC单元102的一部分，在其他实施例中，维持电路也可以是一个具有NFC标签的芯片以及线圈的独立模块（如NFC标签贴）。
在本实施例中，为了将手机2发射的NFC信号转换为MCU能够识别的信号，NFC单元102还包括天线线圈1021和NFC芯片1022，NFC芯片1022与天线线圈1021连接，NFC单元102通过天线线圈1021接收和发送NFC信号，并通过NFC芯片将该NFC信号转换为MCU101能够识别的信号。
在本实施例中，NFC单元还包括至少一个谐振天线或转换线圈，通过谐振天线或转换线圈将手机2发射的NFC信号转换为电流。其中，维持电路的线圈也可以用于将手机2的NFC信号转换为电流。
在本实施例中，为了收集到足够多的射频信号，谐振天线或转换线圈设置在手机保护壳体1靠近手机2的NFC感应区域201的位置。
在一个优选的实施例中，谐振天线或转换线圈设置在手机保护壳体1上与手机2的NFC感应区域201相对的位置。
由于NFC转换的电流为交流电，需要将其转换为直流电才可使用，在本实施例中，整流电路单元105接收NFC单元102传输的交流电，并通过整流电路单元105转换为直流电；整流电路单元105包括全桥整流电路和N倍压整流电路，N≧1。
在本实施例中，由于NFC单元102包括多个用于转换能量的天线或线圈，因此，其收集到的信号强度会按照其与发射信号的区域的距离顺序强弱不同，通过不同的天线或线圈转换得到的电信号的电压也会不同。需要整流电路单元105根据天线或线圈输出的电压进行不同的处理。根据电压情况通过全波整流、倍压整流之一或两者组合方式进行整流。其中，通过全波整流能量转换率高，电压变化小(如半波只有<50%的能量转换效率)；倍压整流可以放大电信号的电压，使之在高压下损耗较小。由于电信号按顺序是衰减的，因此，电压较高的电信号可不经倍压整流处理。
多个天线或线圈输出的电信号经整流电路单元105整流后，通过并联的方式输出整流后的电信号。
由于整流后的多个电信号的电压或电流可能存在差异（比如经过倍压整流和未经过倍压整流的电压、电流可能不同）。故有可能致使整流电路单元105输出的电压不平稳，需要进行稳压处理。
在一个优选的实施例中，手机壳还包括稳压单元，稳压单元包括DC-DC电路，DC-DC电路分别与整流电路单元105、MCU101连接。
DC-DC电路可输出低电压高电流的电信号，这种电信号可减小负载损耗和向支持灯光控制的手机壳提供其工作所需的电压以保障支持灯光控制的手机壳正常工作。如当支持灯光控制的手机壳的芯片工作电压为1.8V时，DC-DC电路可输出1.8V的电压，从而满足支持灯光控制的手机壳工作电压需求的同时，还能提供更稳定足够的电流保障。
在本实施例中，DC-DC电路包括DC-DC芯片和外围元件电路，通过DC-DC电路将整流电路单元105输出的不平稳的电压转换成稳定电压、电流输出，减小支持灯光控制的手机壳的损耗。
在一个优选的实施例中，整流电路单元105还包括LDO电路，LDO电路与DC-DC电路连接，通过LDO电路对DC-DC电路输出的电信号进行线性稳压处理后传输给MCU101和发光单元103。其中，LDO电路由包含LDO芯片和外围元件的电路组成，目的是将电压进行线性输出，供给对需要较小的电源纹波和对电信号精度要求较高的器件，以减小不稳定电压对器件的损耗。
在本实施例中，LDO电路可以直接与整流电路单元105连接或通过DC-DC电路与整流电路单元105连接。区别在于，LDO电路是消耗性原件，直接与整流电路单元105连接后电信号转换效率低；电信号通过DC-DC单元稳压处理后传输给LDO电路时，LDO电路的转换效率高。
在本实施例中，支持灯光控制的手机壳包括输入单元104，输入单元104设置在手机保护壳体1的侧边或背面，与MCU101连接，MCU101通过所述输入单元104获取输入的指令或操作信号。其中，该指令或操作信号可以为切换发光单元103的显示状态、开关NFC单元102以及控制手机2工作状态的指令中的任一种，也可以根据用户需求将其设置为其他能够控制手机2或手机壳工作的指令，在此不做限定。
在本实施例中，发光单元103的显示状态包括颜色、节奏、亮度以及显示范围中的至少一种。
在本实施例中，输入单元104与MCU101通过IO、GPIO、ADC、SPI、I2C、UART用于连接的器件中的至少一个连接，输入单元104通过该器件向MCU101输入指令。
在一个具体的实施例中，输入单元104为两个按键，两个按键分开设置在手机保护壳体1的同一条侧边上。
在本实施例中，发光单元103包括LED灯、LED灯灯带以及导光条中的一种或多种。该发光单元103可以用于显示运行状态、通信状态以及作为发光装饰（如变色、跑马灯等装饰效果）。
在本实施例中，发光单元103设置在手机保护壳体1的侧边或手机保护壳体1的背面。
在一个具体的实施例中，发光单元103为灯条，该灯条设置在手机保护壳体1远离手机2一侧的中部。
在上述实施例中，通信组件、MCU101、整流电路单元105中的一个或多个可以集成在一个SOC中（即上述单元由具有相同功能的SOC替代），也可以分开作为独立单元设置在多个不同的SOC中。
有益效果：本实用新型在手机壳上设置发光单元，增加了手机壳的功能，消除了手机壳功能单一的问题，提高了用户体验，通过NFC单元与手机建立通信连接并利用NFC单元向手机取电，实现了通过手机对发光单元的控制，而且使得手机壳的发光单元可以在无外置供电或者内置电池供电的情况下由终端进行供电，避免了使用电池造成的体积变大和污染，保护了环境。
