 本发明的实施方式
本申请提供一种触控笔及触控系统，为使本申请的目的、技术方案及效果更加清楚、明确，以下参照附图并举实施例对本申请进一步详细说明。应当理解，此处所描述的具体实施例仅用以解释本申请，并不用于限定本申请。
请参见图1，本申请提供了一种触控笔，所述触控笔包括笔身100、笔头200，以及发光器件300；
所述发光器件300设于所述笔头200处，所述笔头的非接触端201与所述笔身的底端101连接；
所述笔身100内部设有控制模块400，所述控制模块400与所述发光器件300电性连接，所述控制模块400用于在所述笔头的接触端202作用于反射式屏幕上时，控制所述发光器件300发光。
在一实施例中，所述发光器件300设置在所述笔头200处，不限于设置在笔头200的内部或外部，所述笔头的非接触端201与所述笔身的底端101连接，所述发光器件300能够进行发光，并为处于光线环境较差的反射式屏幕提供反射光源，以使用户能够正常使用该反射式屏幕；所述笔身100内部设有控制模块400，所述控制模块400与所述发光器件300电性连接，所述控制模块400用于在所述触控笔作用于反射式屏幕上时，控制所述发光器件300发光，当用户使用本发明实施例提供的触控笔，并通过所述触控笔上的接触端202与反射式屏幕有接触操作时，所述触控笔能够接收反射式屏幕发送的感应信号，并且可以根据所述感应信号控制发光器件300进行发光，从而为反射式屏幕提供发送光源，进而使得用户即使在周围环境亮度不足时，仍然能够对反射式屏幕进行正常的操作。
譬如，夜间在室外或是其他周围环境亮度不高的地方使用配备有反射式屏幕的设备时，由于周围环境亮度不足以使该设备的反射式屏幕正常工作，此时通过本发明提供的触控笔的接触端202与反射式屏幕进行接触操作后，所述触控笔自动发光，此时便可将所述触控笔提供的光源作为所述反射式屏幕的反射光源，如此便可正常使用所述配备有反射式屏幕的设备。
此外，在本发明实施例中，所述反射式屏幕包括但不限于为反射型RLCD或墨水屏，只要需要反射光源才能进行正常工作的屏幕，均在本发明的保护范围。
作为本发明的优选实施例，所述发光器件300包括若干个LED灯301，所述若干个LED灯301为一排或多排围绕设置在所述笔头200的外部。
在一实施例中，所述发光器件300可以为任意能够发光的器件，具体的，由于LED灯301高效节能、价格低，并且绿色环保，故本发明实施例采用若干个LED灯301作为所述发光器件300。将所述若干个LED灯301设置在所述笔头200处，优选的，本发明通过将所述LED灯301围绕地设置在所述笔头200的外部，不仅设计和工艺简单，实现成本低，更是能够最大化利用LED灯301的光源，将光源接近反射式屏幕，使得反射式屏幕能够有足够的光源进行反射，供用户浏览更加清晰的内容，提升了用户的体验。
更进一步的，所述笔头200的材质为透明材质；所述LED灯301一排或多排围绕设置在所述笔头200的内部。
本发明通过将所述笔头200的材质设为透明的材质，并将所述若干个LED灯301围绕地设置于所述笔头200的内部，不仅能够提高所述触控笔的美观性，还提高了所述触控笔的安全性；将LED灯301围绕地设置于所述笔头200的内部，能够防止LED灯301的脱落，从而能够防止LED脱落造成所述触控笔的外观及功能的缺失，并且避免了用户直接触摸到LED灯301所带来的安全隐患。
需要说明的是，在本发明实施例中的若干个LED灯301，可以通过设置一排，也可通过设置多排围绕在所述笔头200的内部或外部，具体的LED灯301设置方式不仅仅只限于围绕于所述笔头200的内外部的设置方式，还可以为点缀、排列、散布等设置于所述笔头200的内外部的设置方式，在本发明实施例中，采用围绕的设置方式只是示意性的设置方式，在进行生产本发明所提供的触控笔时，可采用上述提及的任一或多种组合方式进行设置，这些设置方式均在本发明的保护范围内。
请参见图2，图2是本发明实施例提供的触控笔的另一种实施例的结构示意图，本发明实施例提供的触控笔，还包括光感传感器500；所述光感传感器500与所述控制模块400电性连接，所述光感传感器500用于检测周围环境亮度；所述控制模块400，还用于在所述笔头的接触端202作用于反射式屏幕上，且所述光感传感器500检测到周围环境亮度低于第一预设阈值时，控制所述发光器件300发光。
所述触控笔还包括有光感传感器500，将所述光感传感器500与所述控制模块400电性连接，使得控制模块400能够接收所述光感传感器500所产生的信号，从而根据所述信号生成对应的控制指令，并根据生成的控制指令控制所述发光器件300的发光。优选的，本发明通过预先在光感传感器500中设置一个阈值：第一预设阈值，以控制所述光感传感器500在检测到周围环境亮度低于所述第一预设阈值时，生成第一信号，并将所述第一信号发送至所述控制模块400，以使所述控制模块400可根据所述第一信号控制所述发光器件300进行发光。
需要说明的是，用户可根据实际的需求自行更改所述第一预设阈值的大小，从而实现所述触控笔能够在指定的亮度下才进行工作。例如，用户A为户外工作者，经常在夜间户外使用配备有反射式屏幕的设备，周围环境亮度较低，但并未低于所述第一预设阈值，造成所述触控笔无法进行发光，从而使得用户A无法正常使用所述配备有反射式屏幕的设备，基于此种情况，用户A可将所述第一预设阈值调高至实际所需的阈值，以使所述触控笔能够在该环境下正常工作，从而使得用户能够正常使用所述配备有反射式屏幕的设备。
作为本发明的优选实施例，在本发明实施例中，还可设置多个阈值参数以控制所述光感传感器500生成不同的信号，从而使得控制模块400能够根据该不同的信号，控制所述发光器件300发出不同亮度的光，如此不仅能够降低所述触控笔的功耗，还能提高用户的体验。例如，用户A预先设置了三个不同的阈值参数，以控制所述光感传感器500能够生成三种不同的信号，该三种不同的信号分别能够使得所述控制模块400控制所述发光器件300发出三种不同亮度的光，每种亮度的光所需的功耗不同，在较亮的环境中，提供微弱的光源供反射式屏幕进行辅助反射；在较暗的环境中，提供一般亮度的光源供反射式屏幕进行局部反射；在几乎无任何光源的环境中，提供较亮的光源供反射式屏幕进行全部反射；采用本发明提供的实施例，能够最大限度地降低所述触控笔的功耗。
需要指出的是，用户可设置的阈值参数不限于为一个或多个，具体的阈值参数设置个数可根据用户的实际需求进行更改。通过设置多个不同的阈值参数以控制光感传感器500生成多个不同的信号，从而使得所述控制模块400控制所述触控笔的发光器件300发出不同亮度的光，可以最大限度地降低所述触控笔的功耗，节约了用户的使用成本，提高了用户体验。
请继续参见图2，本发明实施例提供的触控笔，还包括压力传感器600；所述压力传感器600与所述控制模块400电性连接，所述压力传感器600用于感应施加于所述触控笔的压力；所述控制模块400，还用于在所述笔头的接触端202作用于反射式屏幕上，且所述压力传感器600感应到施加于所述触控笔的压力大于第二预设阈值时，控制所述发光器件300发光。
所述触控笔还包括有压力传感器600，将所述压力传感器600与所述控制模块400电性连接，使得控制模块400能够接收所述压力传感器600所产生的信号，从而根据所述信号生成对应的控制指令，并根据生成的控制指令控制所述发光器件300的发光。优选的，本发明通过预先在压力传感器600中设置一个阈值：第二预设阈值，以控制所述压力传感器600在感应到施加于所述触控笔的压力高于所述第二预设阈值时，生成第一信号，并将所述第一信号发送至所述控制模块400，以使所述控制模块400可根据所述第一信号控制所述发光器件300进行发光。
需要说明的是，用户可根据实际的需求自行更改所述第二预设阈值的大小，从而实现所述触控笔能够在感应到指定的压力时才进行工作。例如，用户B无论是光线充足或昏暗的环境中都需要经常使用触控笔，那么需将第二预设阈值设置得大于用户B平常习惯使用触控笔时所用的压力，如此便可使得用户B在光线充足的环境中只需按照正常的使用习惯去使用所述触控笔；而在周围环境亮度不足以正常使用配备有反射式屏幕的设备时，用户B只需稍微用力作用于所述触控笔，即可触发所述触控笔的压力传感器600生成第一信号，使得所述控制模块400可根据所述第一信号控制所述触控笔的发光器件300进行发光，从而使得用户B能够在周围环境亮度不足的条件下正常使用配备有反射式屏幕的设备。
作为本发明的优选实施例，在本发明实施例中，还可设置多个阈值参数以控制所述压力传感器600生成不同的信号，从而使得控制模块400能够根据该不同的信号，控制所述发光器件300发出不同亮度的光，如此不仅能够降低所述触控笔的功耗，还能提高用户的体验。例如，用户B预先设置了三个不同的阈值参数，以控制所述压力传感器600能够生成三种不同的信号，该三种不同的信号分别能够使得所述控制模块400控制所述发光器件300发出三种不同亮度的光，每种亮度的光所需的功耗不同，在较亮的环境中，提供微弱的光源供反射式屏幕进行辅助反射；在较暗的环境中，提供一般亮度的光源供反射式屏幕进行局部反射；在几乎无任何光源的环境中，提供较亮的光源供反射式屏幕进行全部反射；采用本发明提供的实施例，能够最大限度地降低所述触控笔的功耗。
需要指出的是，用户可设置的阈值参数不限于为一个或多个，具体的阈值参数设置个数可根据用户的实际需求进行更改。通过设置多个不同的阈值参数以控制压力传感器600生成多个不同的信号，从而使得所述控制模块400控制所述触控笔的发光器件300发出不同亮度的光，可以最大限度地降低所述触控笔的功耗，节约了用户的使用成本，提高了用户体验。
请参见图1和图2，本发明实施例提供的触控笔的笔身100内部还设有供电电池102；所述控制模块400分别与所述供电电池102、所述笔头的接触端202电性连接；所述供电电池102，用于为所述控制模块400供电；所述控制模块400，还用于在接收到反射式屏幕由于与所述笔头的接触端202接触而生成的感应信号时，控制所述发光器件300发光。
在一实施例中，通过在所述触控笔的笔身100内部设有供电电池102，并将所述控制模块400分别与所述供电电池102、所述笔头的接触端202电性连接，使得所述控制模块400能够接收在所述触控笔与所述反射式屏幕进行接触操作时，由所述笔头的接触端202传来的反射式屏幕发送的感应信号，并且可以根据所述感应信号控制所述发光器件300进行发光，从而实现唯有在所述触控笔与所述反射式屏幕进行接触操作时，所述触控笔才进行发光，避免所述触控笔在未接触反射式屏幕的其他任何操作的情况下进行发光，从而防止了所述触控笔不必要的功耗产生，节省了用户的成本，提高了用户体验。
譬如，用户C采用本发明提供的触控笔与反射式屏幕进行接触，该触控笔由于与所述反射式屏幕的接触操作而触发所述发光器件300的发光，用户C则可通过该触控笔的发光器件300提供的光源作为反射式屏幕的反射光源，从而能够正常浏览所述反射式屏幕上的内容；当用户C不需要再使用该触控笔时，将该触控笔随意放置一旁，而在用户C不注意时，存在其他用户D使用该触控笔的可能：用户D随意玩弄所述触控笔，并将所述触控笔随意在各种地方刻画，此时所述触控笔即使接触到了其他物体，但是并未接收到反射式屏幕发送的感应信号，则不控制所述发光器件300进行发光，极大程度地降低了所述触控笔的功耗。
需要说明的是，所述供电电池102可以是可拆卸电池或不可拆卸电池。无论采用何种电池，本发明的触控笔均能够正常地执行上述各个实施例的操作。
在另一实施例中，所述笔身100为太阳能电池板，所述太阳能电池板用于为所述供电电池102充电。
通过将所述触控笔的笔身100设为太阳能电池板，所述太阳能电池板可为本发明提供的供电电池102充电，使得用户无需更换供电电池102，能够使得本发明提供的触控笔更加的绿色环保，并且进一步的降低了用户的成本。
更进一步的，所述笔头的接触端202是由导电材料制成，所述接触端的导电材料为硅胶。
为了获取反射式屏幕发送的感应信号，本发明实施例的所述触控笔的笔头的接触端202将采用导电材料构成；为了方便用户的书写，提高用户的体验，本发明实施例还将硅胶设为所述笔头的接触端202，不仅绿色环保，还能够很好地保护反射式屏幕，防止反射式屏幕出现磨损的情况。
另外，在本发明实施例中，所述发光器件300的色温包括暖色和冷色；所述发光器件300的光源包括单色和彩色；所述发光器件300的光源类型包括RGB和WRGB。

更进一步的，所述触控笔还包括灯光选择按钮，所述灯光选择按钮可供用户选择不同的色温、不同的光源，以及不同光源类型的LED灯301，满足不同用户的需求，进一步的提升了用户体验。
需要说明的是，上述任一实施例提供的触控笔均可以为电容笔，而且可以为主动式电容笔或者被动式电容笔；其中，若为主动式电容笔，可在所述主动式电容笔笔头的接触端与反射式屏幕接触时，通过控制模块发出发射信号至所述反射式屏幕，供所述反射式屏幕根据所述发射信号检测到所述主动式电容笔笔头的接触端与反射式屏幕的接触位置；若为被动式电容笔，则可将所述笔身与所述控制模块电性连接，从而使得该被动式电容笔笔头的接触端与反射式屏幕接触时，反射式屏幕的电信号能够通过该被动式电容笔笔头的接触端传递到用户手上，进而使得所述反射式屏幕确定该被动式电容笔笔头的接触端与反射式屏幕的接触位置。
作为本发明的优选实施例，请参见图3，本发明实施例还提供了一种触控系统，该系统包括上述任一实施例所述的触控笔10，以及反射式屏幕20；其中，该系统中的触控笔10在作用于所述反射式屏幕20时，能够控制其发光器件发光，从而为所述系统中的反射式屏幕20提高反射光源。
综上所述，本发明实施例提供了一种触控笔及触控系统，所述触控笔包括笔身、笔头，以及发光器件；所述发光器件设于所述笔头处，所述笔头的非接触端与所述笔身的底端连接；所述笔身内部设有控制模块，所述控制模块与所述发光器件电性连接，所述控制模块用于在所述笔头的接触端作用于反射式屏幕上时，控制所述发光器件发光。
