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地传达给本领域的技术 人员。
需要说明的是，本发明实施例及优选实施例中的特征在不冲突的前提下可以相互结合。
图1是根据本发明一个实施例的灯具的照射角度调节方法流程图。该实施例中灯具包括多个红外接收器和驱动电机，如图1所示，根据本发明一个实施例的灯具的照射角度调节方法至少包括：
步骤S102，经由多个红外接收器接收来自遥控器的红外信号；
步骤S104，基于多个红外接收器的多个红外信号强度值确定灯具的照射角度调节值；
步骤S106，基于照射角度调节值，经由驱动电机调节灯具的照射角度。
本发明实施例提供了一种灯具的照射角度调节方案，该实施例中灯具包括多个红外传感器和驱动电机，首先，经由多个红外接收器接收来自遥控器的红外信号，随后基于多个红外接收器接收的多个红外信号强度值确定灯具的照射角度调节值，进而基于照射角度调节值，经由驱动电机调节灯具的照射角度。本发明实施例提供的技术方案基于多个红外接收器和驱动电机调节灯具的照射角度，能够实现更好的照明效果，从而满足实际应用中用户的照明需求。进一步的，本发明实施例提供的技术方案在需要调节灯具的照射角度时，只需操控遥控器就可以控制灯具的照射角度，从而实现对灯具的照射角度的智能调节，达到更好的照明效果。
上文步骤S102中的多个红外接收器，其在灯具上的安装位置和安装个数可以有多种选择。参见图2，在本发明一个优选实施例中，灯具包括3个红外接收器，并且3个红外接收器安装在灯具所在平面的外延，且在以灯具为原点建立的XY直角坐标系中，并且设定3个红外接收器的坐标归一化为(0，1)、(-0.5，-0.5)和(0.5，-0.5)。在本优选实施例中，在灯具所在平面的外延安装了3个红外接收器，随后基于在灯具所在平面以灯具为坐标原点建立的XY轴平面直角坐标系，将3个红外接收器的安装位置的坐标归一化为(0，1)、(-0.5，-0.5)和(0.5，-0.5)。这里将3个红外接收器器的坐标归一化为(0，1)、(-0.5，-0.5)和(0.5，-0.5)，即安装位置对应的三个点相互连接形成等腰三角形，并且这3个点在X轴与Y轴上的矢 量和都为零。基于本优选实施例提供的方案，可以建立起易于算法计算的坐标系，进而能够将3个红外接收器的坐标进行归一化，从而简化计算过程。本优选实施例提供的方案最大程度简化了计算复杂度，提高了产品响应速度。
在本发明一实施例中，遥控器上设置有启动按键，遥控器和灯具内部都设置有蓝牙通信模块，遥控器和灯具可以通过蓝牙通信模块进行信号交互。上文步骤S102之前，还可以包括：响应于遥控器按下启动按键，发送照射角度调节启动命令；灯具接收到启动命令后开启红外信号接收。
对于上文步骤S104中提及的照射角度调节值，优选的，照射角度调节值包括X、Y轴调节值。
进一步，步骤S104基于多个红外接收器的多个红外信号强度值确定灯具的照射角度调节值，本发明实施例提供了一种可选的方案，在该方案中，可以以3个红外接收器分别接收的红外信号强度值进行比例叠加算法以分别确定X、Y轴调节值。本发明实施例提供的方案，可以直接将3个红外接收器分别接收的3个红外信号强度值进行比例叠加算法，从而能够快速地确定X轴、Y轴调节值。
上文的比例叠加算法，在本发明一个优选实施例中，
X轴调节值＝红外信号强度值1*0+红外信号强度值2*(-0.5)+
红外信号强度值3*0.5；
Y轴调节值＝红外信号强度值1*1+红外信号强度值2*(-0.5)+
红外信号强度值3*(-0.5)；
在本优选实施例中，红外信号强度值1,2,3分别是3个红外接收器接收的红外信号强度值。本优选实施例提供的方案，由于比例叠加算法易于进行计算，使得X轴调节值和Y轴调节值很容易计算出来，从而提高了调节效率。
这里的比例叠加算法可以解释为将3个红外接收器接收到的3个红外信号强度值按照归一化坐标进行叠加，换言之，是将3个红外信号强度值分别乘以其对应的坐标归一化系数再相加。例如，计算X轴调节值为例，将3个红外信号强度值乘以其对应的X轴坐标归一化系数，即X轴调节值＝红外信号强度值1*0+红外信号强度值2*(-0.5)+红外信号强度值 3*0.5。计算Y轴调节值与此同理，在此不再赘述。
在本发明一优选实施例中，步骤S106中的驱动电机包括X轴方向的转动电机和Y轴方向的转动电机。
进一步，对于步骤S106中经由驱动电机调节灯具的照射角度，优选的，基于照射角度调节值，驱动X轴方向的转动电机和/或Y轴方向的转动电机对灯具的照射角度进行调节。也就是说，在本发明实施例中，一方面可以单独驱动X轴方向的转动电机，进而调节灯具在X轴方向的照射角度。另一方面也可以单独驱动Y轴方向的转动电机，进而调节灯具在Y轴方向的照射角度。此外，还可以同时驱动X轴、Y轴方向转动电机对灯具的照射角度进行调节。本发明实施例提供的方案通过驱动电机的转动来调节灯具的照射角度。
具体调节过程，结合上文中的比例叠加算法进行说明，如果计算后获得的X轴调节值为负，则控制X轴方向的转动电机朝X轴负方向转动，如果X轴调节值为正，则控制X轴方向的转动电机朝X轴正方向转动，如果Y轴调节值为负，则控制Y轴方向的转动电机朝Y轴负方向转动，如果Y轴调节值为正，则控制Y轴方向的转动电机朝X轴正方向转动。
为了满足实时性的要求，在本发明一优选实施例中，上述灯具的照射角度调节方法还可以包括：在驱动电机调节灯具的照射角度的过程中，基于实时更新的红外信号强度值来实时更新X、Y轴调节值，直至X、Y轴调节值为零，停止驱动电机对灯具照射角度的调节。在该实施例中，随着灯具的照射角度的不断变化，红外接收器接收的红外信号强度值也随之改变，X、Y调节值也随之更新，并根据更新的X、Y轴调节值实时控制电机的转动方向，直至X、Y轴调节值为零，则停止电机的转动，调节结束。基于本优选实施例提供的方案，随着灯具照射角度的变化，X、Y轴调节值可以实时更新，从而满足实时性要求。
在本发明一优选实施例中，上述灯具的照射角度调节方法还可以包括：
接收来自遥控器的照射角度调节停止指令，并停止驱动电机对灯具照射角度的调节。在本优选实施例中，当接收到来自遥控器的照射角度调节停止指令时，则停止驱动电机的转动，从而结束对灯具的照射角度的调节。 本优选实施例提供的方案可以按照使用者的意愿对灯具的照射角度进行调节，提升产品使用体验。
基于同一发明构思，本发明实施例还提供了一种可调节照射角度的灯具，图3是根据本发明一个实施例的可调节照射角度的灯具的结构框图。如图3所示，根据本发明实施例的可调节照射角度的灯具的结构框图至少包括：

处理器204，适于基于多个红外信号强度值确定灯具的照射角度调节值，并将照射角度调节值传送至驱动电机；

在一个优选实施例中，照射角度调节值包括X、Y轴调节值，且处理器104还适于以3个红外接收器分别接收的红外信号强度值进行比例叠加算法以分别确定X、Y轴调节值。

在一个优选实施例中，在驱动电机206调节灯具的照射角度的过程中，处理器204还适于基于实时更新的红外信号强度值来实时更新X、Y轴调节值，直至X、Y轴调节值为零，停止驱动电机对灯具照射角度的调节。
在一个优选实施例中，当接收到来自遥控器的照射角度调节停止指令后，处理器204还适于停止驱动电机对灯具照射角度的调节。
基于同一发明构思，本发明实施例还提供了一种灯具的照射角度调节系统。如图5所示，根据本发明实施例的灯具的照射角度调节系统至少可 以包括遥控器300和如上述之任一灯具，遥控器300适于向灯具发射红外信号。
在一个优选实施例中，遥控器300还与灯具无线通信连接，且
遥控器300适于向灯具发送照射角度调节开启信号，并同时向灯具发射红外信号；灯具适于在接收到开启信号之后，开启红外接收器202、处理器204和驱动电机206工作。
在一个优选实施例中，其中遥控器300还适于向灯具发送照射角度调节停止信号，并同时关闭发射红外信号；灯具还适于在接收到停止信号之后，停止红外接收器202、处理器204和驱动电机206的工作。
本发明实施例提供了一种灯具的照射角度调节方案，该实施例中灯具包括多个红外传感器和驱动电机，首先，经由多个红外接收器接收来自遥控器的红外信号，随后基于多个红外接收器接收的多个红外信号强度值确定灯具的照射角度调节值，进而基于照射角度调节值，经由驱动电机调节灯具的照射角度。本发明实施例提供的技术方案能够基于多个红外接收器和驱动电机调节灯具的照射角度，能够实现更好的照明效果，从而满足实际应用中用户的照明需求。进一步的，本发明实施例提供的技术方案在需要调节灯具的照射角度时，只需操控遥控器就可以控制灯具的照射角度，从而实现对灯具的照射角度的智能调节，达到更好的照明效果。
