具体实施方式
为使本发明的目的、技术方案和优点更加清楚，下面将结合附图对本发明实施方式作进一步地详细描述。
请参考图1，其示出了本发明一个实施例提供的台灯10的结构示意图，该台灯10可以用于阅读、学习、工作等的照明。参见图1，该台灯10包括：基座101、灯柄102、设置有光源的灯头103和调节部件104。
其中，灯柄102分别与基座101、灯头103和调节部件104固定连接。基座101能够放置在放置面M上，且基座101的底面A为弧面，台灯10的重心落在基座101上。
其中，调节部件104能够通过改变调节部件104的重心来调节台灯10的重心，从而改变基座101的底面A与放置面的接触位置，带动灯头103的照明角度改变。如图1所示，调节部件104可以包括：灯尾柄1041和砝码1042。根据一种具体的实施方式，可以通过调节位于所述灯尾柄1041上的所述砝码1042的个数和/或所述砝码1042的位置来改变所述调节部件的重心。
进一步地，如图1所示，台灯10还包括：电源线106。
基座101和灯柄102上均可以设置有供电源线106通过的通道(图1中未示出)，电源线106可以依次通过基座101上的通道和灯柄102上的通道，与灯头103连接。与电源线106连接的电源通过电源线106为灯头103供电。
需要说明的是，为了达到节能、环保、高效的照明效果，本发明中的光源为发光二极管(LED)光源。
还需要说明的是，在本发明的若干实施例中，灯头103可以包括灯壳和LED光源，灯壳上可以设置有卡接槽，LED光源卡接在卡接槽中，与灯壳固定；或者，LED光源为杆状结构，灯壳上可以设置有卡接孔，LED光源的一端卡接在卡接孔内，与灯壳固定，或者，灯壳和LED光源还可以为其他的固定方式，本发明实施例对此不做限定。可替换地，灯头103可以仅包括能够与灯柄102固定连接的光源，本发明实施例不对灯头103做具体限定。
综上所述，本发明的一个实施例提供的台灯，通过将基座的底面设置为弧面，使得通过改变调节部件的重心来调节台灯的重心时，基座的底面与放置面的接触位置能够改变，进而带动灯头的照明角度改变。由于所述技术方案通过调节台灯的重心来调节灯头的照明角度，无需旋转灯头，解决了旋转灯头导致灯柄与灯头的连接部位断裂、影响台灯的使用寿命的问题，达到了避免灯头断裂，延长台灯使用寿命的效果。
进一步地，如图2所示，其示出的是图1所示实施例中所述台灯10的基座101的截面图，该基座101放置于放置面M上。基座101内 可以设置空腔O，空腔O的底部可以设置固定重力块105，用于稳定所述基座101和所述台灯10。可选地，固定重力块105在空腔O的底部的位置能够随着图1中基座101的底面A与放置面的接触位置的改变而改变。在一种可能的实现方式中，固定重力块105可以由砂石制成，示例地，固定重力块105可以由砂石制成并放置在空腔O的底部；在另一种可能的实现方式中，当空腔O为密封空腔时，固定重力块105还可以由液体制成并盛放于空腔O内，其中，当固定重力块105由液体制成时，该液体的具体材质以该液体不影响台灯10的工作为准，且该液体的质量较重。
需要说明的是，图2是以基座101为圆柱状结构为例进行说明的，其中，圆柱状结构的侧面即为图1中基座101的底面A。而事实上，基座101还可以为其他底面为弧面的结构，如，球形等，本发明实施例不对基座101的形状做具体限定。
进一步地，如图1所示，调节部件104可以包括：灯尾柄1041和砝码1042。
其中，砝码1042的个数可以为预设数值，例如1或2。可选地，灯尾柄1041可以为杆状结构，其一端与灯柄102固定连接，砝码1042能够固定在灯尾柄1041上。通过调节位于灯尾柄1041上的砝码1042的个数和/或砝码1042的位置能够改变调节部件104的重心。即，通过调节灯尾柄1041上的砝码1042的个数来改变调节部件104的重心，或者通过调节灯尾柄1041上的砝码1042的位置来改变调节部件104的重心，或者同时调节位于灯尾柄1041上的砝码1042的个数和砝码1042的位置来改变调节部件104的重心。
为了实现灯尾柄1041上的砝码1042的个数和/或砝码1042的位置的调节，本发明的一些实施例提供了以下两种砝码1042与灯尾柄1041的固定方式：
第一种方式，砝码1042与灯尾柄1041通过吸附的方式固定。
例如，砝码1042或灯尾柄1041可以具有磁性，从而使得所述砝码1042能够吸附在所述灯尾柄1041上。在一个具体实现中，砝码1042可以具有铁磁性，灯尾柄1041可以由铁制成；或者在另一个具体实现中，灯尾柄1041可以具有铁磁性，砝码1042可以由铁制成。通过这种方式可以使得砝码1042能够吸附在灯尾柄1041上，实现砝码1042 与灯尾柄1041的固定。
第二种方式，砝码1042与灯尾柄1041通过套接的方式固定。
一方面，如图3所示，其示出的是图1所示实施例中所述台灯10的一种调节部件104的结构示意图。砝码1042可以为环状结构，灯尾柄1041可以为圆柱状结构。灯尾柄1041的侧面设置有卡块10411，该卡块10411可以包括：固定卡块10411a和活动卡块10411b，砝码1042套接在灯尾柄1041上，并通过卡块10411卡接在灯尾柄1041上。
其中，固定卡块10411a和活动卡块10411b都可以有一个或多个。固定卡块10411a固定设置在灯尾柄1041上。示例地，固定卡块10411a可以焊接在灯尾柄1041上。活动卡块10411b在灯尾柄1041上的位置能够改变。例如，活动卡块10411b或灯尾柄1041可以具有磁性，从而使得活动卡块10411b能够吸附在灯尾柄1041上。在一个具体实现中，活动卡块10411b可以具有铁磁性，灯尾柄1041可以由铁制成，或者灯尾柄1041可以具有铁磁性，活动卡块10411b可以由铁制成，活动卡块10411b能够吸附在灯尾柄1041上。可替换地，活动卡块10411b可以为由可形变的材料制成且设置有开口的环状结构，活动卡块10411b能够通过活动卡块10411b的开口固定在灯尾柄1041上。需要说明的是，本发明实施例中的固定卡块10411a和活动卡块10411b的形状可以相同，也可以不同。固定卡块10411a和活动卡块10411b的形状还可以为其他的形状，本发明实施例对此不做限定。
还需要说明的是，本发明实施例中的卡块10411也可以只包括固定卡块10411a，或，只包括活动卡块10411b。具体地：
如图4所示，其示出的是图1所示实施例中所述台灯10的另一种调节部件104的结构示意图，在图4中，卡块10411只包括固定卡块10411a，砝码1042套接在灯尾柄1041上，并通过固定卡块10411a卡接在灯尾柄1041上。示例地，砝码1042的直径大于灯尾柄1041的直径与固定卡块10411a的高度之和。将砝码1042套接在灯尾柄1041上之后，砝码1042与固定卡块10411a接触，由于受到自身重力及固定卡块10411a的支撑力的作用，可以通过固定卡块10411a卡接在灯尾柄1041上。其中，固定卡块10411a的高度为固定卡块10411a垂直于灯尾柄1041侧面的方向上的长度。
如图5所示，其示出的是图1所示实施例中所述台灯10的再一种 调节部件104的结构示意图。在图5中，卡块10411只包括活动卡块10411b，砝码1042套接在灯尾柄1041上，并通过活动卡块10411b卡接在灯尾柄1041上。示例地，活动卡块10411b吸附在灯尾柄1041上，或者活动卡块10411b通过活动卡块10411b的开口固定在灯尾柄1041上。将砝码1042套接在灯尾柄1041上，砝码1042与活动卡块10411b接触，由于受到自身重力及活动卡块10411b的支撑力的作用，可以通过活动卡块10411b卡接在灯尾柄1041上。
另一方面，如图6所示，其示出的是图1所示实施例中所述台灯10的一种砝码1042的结构示意图。砝码1042可以为环状结构，且砝码1042的侧面可以设置有开口a。可选地，该砝码1042可以由可形变的材料制成，如铁、铜等金属，开口a的大小能够调节。
如图7所示，其示出的是图1所示实施例中所述台灯10的又一种调节部件104的结构示意图。其中，砝码1042能够通过调节开口a的大小套接在灯尾柄1041上。当从灯尾柄1041上取下砝码1042时，为了避免砝码1042丢失，可以将取下的砝码1042套接在灯柄102上。示例地，操作砝码1042使得砝码1042能够通过开口a套接在灯尾柄1041上。之后继续操作砝码1042使得砝码1042的开口a减小直至砝码1042与灯尾柄1041固定。
综上所述，在根据本发明一个实施例提供的台灯中，通过将基座的底面设置为弧面，使得通过改变调节部件的重心来调节台灯的重心时，基座的底面与放置面的接触位置能够改变，进而带动灯头的照明角度改变。由于所述技术方案通过调节台灯的重心来调节灯头的照明角度，无需旋转灯头，解决了旋转灯头导致灯柄与灯头的连接部位断裂、影响台灯的使用寿命的问题，达到了避免灯头断裂，延长台灯使用寿命的效果。
图8是本发明一个实施例提供的台灯10的照明角度调节原理图。首先，将台灯10放置在放置面M上。然后，调节灯尾柄1041上的砝码1042的位置，从而导致调节部件104的重心改变(向图8中的左侧移动)，进而带动台灯10的重心改变(向图8中的左侧移动)。在重力作用下，台灯10发生旋转(向图8中的左侧或逆时针方向旋转)，因此基座101的底面A与放置面的接触位置改变，灯头103的照明角度也相应改变。假设调节前灯头103的照明角度为灯头103与水平方 向x的夹角m，则在调节砝码1042的位置，使得砝码1042远离灯头103的过程中，灯头103的照明角度m会增大为n。若需减小灯头103的照明角度，则可以调节砝码1042的位置，使得砝码1042靠近灯头103，这样灯头103的照明角度m会减小。如此反复，可以将灯头103的照明角度调节至最佳照明角度。
可替换地，本发明一个实施例提供的台灯10还可以通过调节砝码1042的个数来调节灯头103的照明角度。示例地，将台灯10放置在放置面M上，向灯尾柄1041上加砝码1042，调节部件104的重心改变，进而带动台灯10的重心改变。在重力作用下，台灯10发生旋转，因此基座101的底面A与放置面的接触位置改变，灯头103的照明角度也相应改变。假设调节前灯头103的照明角度为灯头103与水平方向的夹角m，则在加砝码1042的过程中，灯头103的照明角度会增大。若需减小灯头103的照明角度，则可以将砝码1042从灯尾柄1041取下，取下砝码1042的过程中，灯头103的照明角度减小。如此反复，可以将灯头103的照明角度调节至最佳照明角度。
可替换地，本发明一个实施例提供的台灯10还可以通过同时调节砝码1042的个数和砝码1042的位置，来调节灯头103的照明角度。示例地，将台灯10放置在放置面上，向灯尾柄1041上加砝码1042，同时调节砝码1042的位置，调节部件104的重心改变，进而带动台灯10的重心改变。在重力作用下，台灯10发生旋转，因此基座101的底面A与放置面的接触位置改变，灯头103的照明角度也相应改变。假设调节前灯头103的照明角度为灯头103与水平方向的夹角m，则加砝码1042并调节砝码1042的位置使得砝码1042远离灯头103的过程中，灯头103的照明角度会增大。若需减小灯头103的照明角度，可以取下砝码并调节剩余砝码1042的位置，使得剩余砝码1042靠近灯头103，这样灯头103的照明角度就会减小。如此反复，可以将灯头103的照明角度调节至最佳照明角度。
需要说明的是，通过调节砝码1042的个数来调节灯头103的照明角度，以及通过同时调节砝码1042的个数和砝码1042的位置来调节灯头103的照明角度的过程和原理已经在上面解释过了。本领域普通技术人员能够理解所述原理并可以参考图8得到其原理图。
综上所述，在本发明的一些实施例提供的台灯中，通过将基座的 底面设置为弧面，使得改变调节部件的重心来调节台灯的重心时，基座的底面与放置面的接触位置能够改变，进而带动灯头的照明角度改变。由于所述技术方案通过调节台灯的重心来调节灯头的照明角度，无需旋转灯头，解决了旋转灯头导致灯柄与灯头的连接部位断裂、影响台灯的使用寿命的问题，达到了避免灯头断裂，延长台灯使用寿命的效果。
