在具体实施时，本公开文本一些实施例所述可调光玻璃可以被应用于各个需要自动控制遮光的场景，例如可以用于车辆行驶时便于自动为驾驶者根据外部射入车辆的光线而调节遮光区域，也可以应用于可根据需要确定是否防窥的观景窗或阳光房内，更可以应用于任何需要根据实际需要调节透光率的场景。
具体地，如图6和7中所示，所述可调光还包括玻璃基底，其中，所述多个调光单元是多个电致变色单元，所述多个电致变色单元以阵列形式排列在所述玻璃基底上；
每一所述电致变色单元能够单独被控制而改变颜色并改变透光率。
在实际操作时，根据一种具体实施方式，所述可调光玻璃可以包括设置于玻璃基底上的多个阵列排列的电致变色单元，每一个电致变色单元的颜色和透光率可以单独改变，以适应各个可调光区域不同的颜色和透光率的要求。

在实际操作时，根据另一种具体实施方式，所述可调光玻璃也可以包括液晶调光玻璃，该液晶调光玻璃包括的每一个液晶膜的透光率能够通过调节其上的电压而单独变化，以适应各个可调光区域不同的颜色和透光率的要求。
在具体实施时，所述可调光玻璃的类型并不限于以上实施例，只要是能 够被控制而调整透光率的玻璃都在本公开文本的保护范围之内。本公开文本一些实施例所述的可控遮光装置，包括上述的可调光玻璃；
如图1所示，本公开文本一些实施例所述的可控遮光装置还包括：

本公开文本一些实施例所述的可控遮光装置通过采用包括多个能单独调光的可调光区域的可调光玻璃，并通过光强探测单元来探测透过该可调光玻璃的光的光强，通过透光控制单元根据该光强调节可调光区域的透光率，以能随着透过可调光玻璃的光强来调节相应的可调光区域的透光率，能够自动调节可调光玻璃的遮光位置。
具体地，本公开文本一些实施例所述的可调光玻璃可以应用于车辆，以提高行车舒适度和安全度。
本公开文本一些实施例所述的可调光玻璃可以应用于车辆，所述光强探测单元具体用于探测透过所述可调光玻璃射向车辆内部的光的光强。在实际操作时，所述可调光玻璃可以作为车辆的前挡风玻璃，也可以作为车辆的侧挡风玻璃和/或后挡风玻璃，下面以作为车辆的前挡风玻璃的可调光玻璃为例说明可调光玻璃的变色区域、驾驶者、太阳光和行车方向之间的关系。
如图2A所示，当本公开文本一些实施例所述的可调光玻璃21应用于车辆时，可调光玻璃21作为车辆的前挡风玻璃使用，车辆的行车方向是前方，太阳在可调光玻璃的左前上方，驾驶者20坐于可调光玻璃21的后方，此时图2A中示出的可调光玻璃21上的待调光区域22受到的照射至驾驶者20的太阳光的光强最大，因此该可调光玻璃21包括的该待调光区域22的透光率 被调低以免驾驶者20受太阳光的干扰而造成眼睛损伤以及干扰驾驶。在图2A中，标号为10的为太阳，箭头方向为行车方向。
如图2B所示，本公开文本一些实施例所述的可调光玻璃21应用于车辆时，可调光玻璃21作为车辆的前挡风玻璃使用，车辆的行车方向是左前方，太阳在可调光玻璃的前上方，驾驶者20坐于可调光玻璃21的后方，此时图2B中示出的可调光玻璃21上的待调光区域22受到的照射至驾驶者的太阳光的光强最大，因此该可调光玻璃21包括的该待调光区域22的透光率被调低以免驾驶者20受太阳光的干扰而造成眼睛损伤以及干扰驾驶。在图2B中，标号为10的为太阳，箭头方向为行车方向。
根据一种具体实施方式，所述光强探测单元还用于探测透过所述可调光玻璃的光的光强最大值，确定具有该光强最大值的光的照射方向为最大光强方向，并输出发射控制信号、所述光强最大值和所述最大光强方向；
所述透光控制单元，与所述光强探测单元电连接，具体用于当接收到所述发射控制信号时，根据该最大光强方向和所述光强探测单元的位置确定待调光区域，控制调降所述待调光区域的透光率；所述待调光区域为具有该最大光强的光线与所述可调光玻璃的重合点所属的可调光区域。
本公开文本一些实施例所述的可控遮光装置通过光强探测单元探测通过可调光玻璃的光的光强最大值以及最大光强方向，并通过透光控制单元确定如果需要降低驾驶者受到的光照强度需要控制调降的待调光区域，通过透光控制单元控制调降该待调光区域的透光率。在实际操作时，当本公开文本一些实施例所述的可调光玻璃应用于车辆时，本公开文本一些实施例所述的可控遮光装置通过光强探测单元探测通过可调光玻璃射向车辆内部的光的光强最大值以及最大光强方向，并通过透光控制单元确定如果需要降低驾驶者受到的光照强度需要控制调降的待调光区域，通过透光控制单元控制调降该待调光区域的透光率，以保护驾驶者。
当本公开文本一些实施例所述的可调光玻璃应用于车辆时，该光强探测单元设置于车辆内部，可选情况下所述光强探测单元设置于驾驶者位置处，所述光强探测单元可以以穿戴物实现，也可以以吊坠方式实现，或者所述光强探测单元可以设置于驾驶者佩戴的墨镜上，各种实现方式都可以，只要能 够准确地测得驾驶者在车辆内收到的光照强度即可。
可选地，所述透光控制单元还用于比较所述光强最大值和预定阈值光强，并当所述光强最大值小于所述预定阈值光强时控制所述待调光区域的透光率为初始透光率；所述初始透光率为所述待调光区域初始未被调节时的透光率。也即如果光强最大值也小于预定阈值光强，说明外部环境(当应用于车辆时驾驶环境)是阴天或者夜间等不需要遮光的情况，则不需要对可调光玻璃的透光率进行调节。
根据一种具体实施方式，所述光强探测单元用于以其位置为原点确定具有该光强最大值的光的照射方向为最大光强方向；
所述透光控制单元包括信号发生器以及多个信号接收器；
每一所述信号接收器分别设置于一相应的电致变色单元或一相应的液晶膜上；
所述信号发生器设置于所述光强探测单元处，所述信号发生器的位置坐标与所述光强探测器的位置坐标重合；
所述信号发生器与所述光强探测单元电连接，用于当接收到所述发射控制信号时向所述可调光玻璃沿着所述最大光强方向发射调节控制信号；
接收到所述调节控制信号的所述信号接收器用于控制相应的电致变色单元改变颜色并降低透光率；或者，接收到所述调节控制信号的所述信号接收器用于控制相应的液晶膜降低透光率。
由于两点确定一条直线，提供光强最大值的光源处与光强探测单元必然确定一条直线，该直线与车上的可调光玻璃必然交汇在一点，该点所属的电致变色单元上设置的信号接收单元会接收到信号发生器发射的调节控制信号，从而控制该可调光区域电致变色单元改变颜色并降低透光率。
本公开文本一些实施例所述的可控遮光装置，应用于车辆，包括可调光玻璃、光强探测单元和透光控制单元，其中，
所述可调光玻璃，包括玻璃基底以及设置于所述玻璃基底上的呈阵列排列的多个电致变色单元，并每一所述电致变色单元能够单独被所述透光控制单元控制而改变颜色并改变透光率；
所述光强探测单元，设置于驾驶者位置处，用于360度探测环境光强， 以探测器位置坐标为原点，确定具有该光强最大值的光的照射方向为最大光强方向；
所述透光控制单元，包括信号发生器以及多个信号接收器；
每一所述信号接收器分别设置于一相应的电致变色单元上；
所述信号发生器设置于所述光强探测单元处；
所述信号发生器的位置坐标与所述光强探测器的位置坐标重合，同在原点，所述信号发生器可沿着最大光强方向可调光玻璃发射调节控制信号；
因为两点确定一直线，提供具有该光强最大值的光的光源和光强探测单元必然确定一条直线，该直线与车上的可调光玻璃必然交汇在一点，而可调光玻璃的每个电致变色单元上都设置有信号接收器，一旦一信号接收器接收到信号发生器发射的调节控制信号，即在该信号接收器设置于的电致变色单元上施加电压，使得该电致变色单元变色并降低透光率，以达到遮光的目的。
在实际操作时，本公开文本所述的可控遮光装置的一些实施例中的电致变色单元也可以被替换为液晶膜，对可调光玻璃采用的材料并不作限定。
如图3所示，本公开文本所述的可控遮光装置的一些实施例的具体实现过程如下：
S1：光强探测单元360°探测环境光强，以光强探测单元的位置坐标为原点确定最大光强方向；
S2：与光强探测单元位置坐标重合的信号发生沿着最大光强方向朝可调光玻璃发射调节控制信号；
S3：接收到所述调节控制信号的信号接收器控制相应的电致变色单元变色并降低透光率。
根据另一种具体实施方式，所述光强探测单元用于在不同的探测时刻分别探测透过所述可调光玻璃射向车辆内部的光的最大光强，确定具有该最大光强的光的照射方向为相应的最大光强方向；
如图4所示，本公开文本一些实施例所述的可控遮光装置上除了包括可调光玻璃(图4中未示出)、光强探测单元41和透光控制单元42之外，所述可控遮光装置还包括存储单元43和比较单元44；
所述存储单元43，与所述光强探测单元41电连接，用于存储第一最大 光强方向、第二最大光强方向和第二最大光强；所述第一最大光强方向是所述光强探测单元在相邻上一探测时刻确定的最大光强方向，所述第二最大光强方向是所述光强探测单元在当前探测时刻确定的最大光强方向，所述第二最大光强是所述光强探测单元在当前探测时刻探测到的最大光强；
所述比较单元44，分别与所述存储单元43和所述光强探测单元41电连接，用于比较所述第一最大光强方向和所述第二最大光强方向，并当所述第一最大光强方向和所述第二最大光强方向不同时输出变换控制信号，当所述第一最大光强和所述第二最大光强方向相同时输出维持控制信号；
所述透光控制单元42，与所述比较单元44电连接，还用于当接收到所述维持控制信号时确定第一待调光区域，控制维持所述第一待调光区域的透光率，当接收到所述变换控制信号时确定第二待调光区域，控制调降所述第二待调光区域的透光率；所述第一待调光区域为具有该第一最大光强方向的光线与所述可调光玻璃的重合点所属的可调光区域，所述第二待调光区域为具有该第二最大光强方向的光线与所述可调光玻璃的重合点所属的可调光区域。
在如图4所示的可控遮光装置在工作时，光强探测单元41会在不同的探测时刻分别探测透过可调光玻璃射向车辆内部的光的最大光强，并确定具有该最大光强的光的照射方向为相应的最大光强方向；
光强探测单元41的探测时刻的选取可以是每隔预定时间设定一次探测时刻，也可以是在光强探测单元41探测到的光强比较大的时间段设定的探测时刻的次数比较多，可以是根据使用者的需求来选取，也可以是通过其他的选取策略来选取，并不作限定；
光强探测单元41在相邻上一探测时刻探测到的最大光强为第一最大光强，确定具有第一最大光强的光的照射方向为第一最大光强方向；
光强探测单元41在当前探测时刻探测到的最大光强为第二最大光强，确定具有第一最大光强的光的照射方向为第一最大光强方向；
存储单元43存储第一最大光强方向、第二最大光强方向以及当前探测时刻探测得到的最大光强(即第二最大光强)；
比较单元44比较该第一最大光强方向和第二最大光强方向；
如果比较单元44比较得到第二最大光强方向和第一最大光强方向不同时，即说明当前的最大光强方向和相邻上一探测时刻的最大光强方向不同，需要改变待调节区域，则比较单元44输出变换控制信号，当透光控制单元42接收到所述变换控制信号时确定第二待调光区域，控制调降所述第二待调光区域的透光率；所述第二待调光区域为具有该第二最大光强方向的光线与所述可调光玻璃的重合点所属的可调光区域；
如果比较单元44比较得到第二最大光强方向和第一最大光强方向相同时，即说明当前的最大光强方向和相邻上一探测时刻的最大光强方向相同，不需要改变待调节区域，则比较单元44输出维持控制信号，当透光控制单元42接收到所述维持控制信号时确定第一待调光区域，控制维持所述第一待调光区域的透光率；所述第一待调光区域为具有该第一最大光强方向的光线与所述可调光玻璃的重合点所属的可调光区域。
可选地，所述透光控制单元还用于当接收到所述变换控制信号时控制调升所述第一待调光区域的透光率，也即当透过第一待调光区域的光的光强并非是当前探测时刻的最大光强时，可以相应调升所述第一待调光区域的透光率。
具体地，所述比较单元还用于接收来自所述存储单元的第二最大光强，比较所述第二最大光强与预定阈值光强，并当所述第二最大光强小于所述预定阈值光强时输出透光控制信号；
所述透光控制单元还用于当接收到所述透光控制信号时控制所述第二待调光区域的透光率为初始透光率，所述初始透光率为所述待调光区域初始未被调节时的透光率。
当所述比较单元比较得到当前探测时刻探测得到的第二最大光强小于预定阈值光强时，说明此时处于阴天或夜间等不需要遮光的情况，则不需对第二待调光区域的透光率进行调节。
具体地，所述光强探测单元用于以其位置为原点确定具有该最大光强的光的照射方向为相应的最大光强方向；
所述透光控制单元包括信号发生器以及多个信号接收器；
所述信号发生器设置于所述光强探测单元处，所述信号发生器的位置坐 标与所述光强探测器的位置坐标重合；
每一所述信号接收器分别设置于一相应的电致变色单元或一相应的液晶膜上；
所述信号发生器与所述比较单元连接，所述信号发生器用于当接收到所述维持控制信号时向所述可调光玻璃沿着所述第一最大光强方向发射第一调节控制信号，当接收到所述变换控制信号时向所述可调光玻璃沿着所述第二最大光强方向发射第二调节控制信号；
接收到所述第一调节控制信号的所述信号接收器用于控制维持相应的第一电致变色单元的颜色和透光率；接收到所述第二调节控制信号的所述信号接收器用于控制相应的第二电致变色单元改变颜色并降低透光率；或者，接收到所述第一调节控制信号的所述信号接收器用于控制维持相应的第一液晶膜的透光率；接收到所述第二调节控制信号的所述信号接收器用于控制相应的第二液晶膜降低透光率。
由于两点确定一条直线，提供光强最大值的光源处与光强探测单元必然确定一条直线，该直线与车上的可调光玻璃必然交汇在一点，该点所属的电致变色单元或液晶膜上设置的信号接收单元会接收到信号发生器发射的第一调节控制信号或第二调节控制信号，从而控制维持第一电致变色单元的颜色和透光率或控制第二电致变色单元改变颜色并降低透光率，或者控制维持第一液晶膜的透光率或控制第二液晶膜降低透光率。
可选地，接收到所述第二调节控制信号的所述信号接收器还用于控制距离所述第二电致变色单元预定距离内的所有电致变色单元都改变颜色并降低透光率；或者，接收到所述第二调节控制信号的所述信号接收器还用于控制距离所述第二液晶膜预定距离内的所有液晶膜都降低透光率。
由于可调光玻璃上接收到最大光强的电致变色单元或液晶膜周围的电致变色单元或液晶膜通常接收的光的光强通常都比较大，因此可以控制也同时调降接收到最大光强的电致变色单元周围的电致变色单元的透光率，以加强遮光效果。
