实施例一
如图2所示，图2为电致液晶雾化膜的工作原理示意图。电致液晶雾化膜也称电致液晶雾化玻璃、电控雾化膜、电控雾化玻璃、通电雾化膜、通电雾化玻璃等，是在两层玻璃或塑料之间注入液晶与液体聚合物的混合物，再将其固化，形成了夹层结构，因此，其可以是玻璃形态，也可以是贴膜形态。根据液晶在电场中发生偏转的特性，可以通过电致液晶雾化膜实现对玻璃过光状态的控制。图2为电致液晶雾化膜开态和关态的光路对比示意图。其中左侧为开态(通电工作状态)的光路示意图，右侧为关态(断电停止状态)的光路示意图。如关态光路示意图所示，在没有施加电压的情况下，液晶是随机排列的，这时光线照到电致液晶雾化玻璃上会发生散射，就像遇到了磨砂玻璃一样，外观上看起来是乳白色的，透光但不透明。如开态光路示意图所示，当在布置于两个夹层上的两个电极上施加足够的电压时，两块玻璃之间产生的静电场让液晶平行排列，使得光线得以透过液晶形成的小液滴而只发生很少的散射。当调节施加电压至较低水平，此时液晶排列出于散落和平行排列中间的某个状态，只让少部分光通过，实现半透明效果，因此，通过调节所施加的电压可以控制电致液晶雾化膜的透明程度，实现多阶控制效果。可以在液晶与液体聚合物的混合物中添加颜色粒子使其具有对应的颜色。另外，电致液晶雾化膜具有透光性好、轻薄、节能、柔软、抗低温、耐高温的特点，非常容易集成到照明***中。

如图1所示，控制组件170可以是电源开关，此时可以视为人工模式，通过用户手动开关电源开关，控制模块110检测到对应控制信号，使遮罩驱动模块140进入通电或断电状态，致使电子遮罩150进入关态或开态，从而实现光线均匀度控制，控制发光模块130发出的光线的散射状态，实现探照光模式和均匀光模式的切换。

实施例四
本示例通过结合2阶独立单元构成的电子遮罩对本发明进行说明。
如图6所示，图6为本发明实施例提供的探照光模式和均匀光模式的光照效果对比示意图。以多功能手电筒为例，多功能手电筒有两种相互独立的光照功能，一种是探照灯的功能，另外一种是户外露营灯功能。601为常见的手电筒的探照灯光照效果，其中，中心区域为高亮区域，周围一圈为次光亮区域；602为户外露营灯的均匀光光照效果。多功能手电筒的两个功能独立运作，因此，在生产的时候只有多增加LED灯珠，不但造成生产成本的增加，还增加了资源的浪费，更增加了环境污染的风险。
通过本发明，结合2阶独立单元构成的电子遮罩对手电筒的探照光进行控制。当电子遮罩断电的时候，为雾化状态，对手电筒的探照光进行散射作用，生成均匀光的光照效果；当为通电的时候，为透明状态，对手电筒的探照光直接通过，依然保持探照光的光照效果。这样，不但可以减少生产成本，节约了资源，还减少环境污染。
通过上述方法，实现探照光和均匀光的切换功能，可以提供多种不同光线散射度的照明效果，实现在不同应用场景、不同环境的更好的照明效果，提高了设备的方便性，并大大提高了用户的和使用体验感。
实施例五
本示例通过结合2阶环形单元构成的电子遮罩对本发明进行说明。
如图7所示，图7为本发明实施例提供的多个模块组成的电子遮罩的弱化中心强光的光线运动对比示意图。
如图8所示，图8为本发明实施例提供的多个模块组成的电子遮罩的弱化中心强光的光照效果对比示意图，即为图7的光照效果示意图。
通过本发明，结合2阶多个环形单元构成的电子遮罩对手电筒的探照光进行控制。
当电子遮罩通电为透明状态的时候，如701所示，701为探照光在电子遮罩为透明状态下光线运动示意，由于电子遮罩为透明状态，光线可以正常穿过，从图中可见通过聚光装置的作用下，光线被聚集在中心区域，形成高亮的照射区域，而其他地方则为次亮区域，其光照效果如801所示。中心高亮区域适合远景探照，但要照射近景的时候，与周围漆黑环境形成高对比度，于是只能看见白茫茫一片，不利于观察近景的实物。
当电子遮罩断电为雾化状态的时候，如702所示，702为探照光在电子遮罩中心区域为雾化状态***区域为透明的光线运动示意，由于电子遮罩中心区域为雾化状态，经过中心区域的光线被散射无法集中到中心区域，于是中心区域范围被扩大形成亮度较小的均匀光区域，而***区域由于透明状态，因此***区域并没有发生改变，如802所示。通过该模式，可以在保持次光亮区域大小不变的情况下，扩大中心区域大小，并减少中心区域的亮度，更适合近景的观察。同理，该效果也可以通过只占中心区域的独立单元构成的电子遮罩或控制多个栅格单元构成的电子遮罩形成中心区域的雾化实现，在此不再赘述。
当通过控制模块控制电子遮罩全部为雾化效果的时候，则呈现如图6中602所示的均匀光效果。
通过上述三种模式的切换，可以探照光设备既可以适用于远景，也可以使用于近景，也可以形成均匀光，使照明设备具有更丰富的照射效果和功能，实现在不同应用场景、不同环境的更好的照明效果，提高了设备的方便性，并大大提高了用户的和使用体验感。
实施例六
本示例通过结合8阶独立单元构成的电子遮罩对本发明进行说明。
图9为本发明实施例提供的拍摄场景下控制光照距离和强度的光照效果对比示意图。在黑暗环境下使用手机后置补光灯进行补光的时候，当拍摄距离比较远(例如5米)的时候，可以通过控制模块控制电子遮罩为1阶透明状态，透明度为100％，散射效果最弱，901为后置补光灯的探照光在电子遮罩为透明状态下光照效果示意，由于电子遮罩为透明状态，光线可以正常穿过，光线为探照光效果，可以照射距离比较远，适合远距离拍摄。
当拍摄距离比较近(例如0.8米)的时候，探照灯效果比较耀眼，并且过度集中，不适合近距离拍摄，于是，可以通过控制模块控制电子遮罩为8阶雾化状态，透明度为0％，散射效果最强，902为8阶雾化状态的均匀光光照效果，光线经过散射使照射角度最大化，光强度最小化，使其适合近距离拍摄。
当拍摄距离稍远(例如2.5米)的时候，使用探照灯过强，而使用均匀光则过弱，于是可以通过控制模块调节适当的阶梯调节度，假设该距离5阶比较合适，则透明度为57％，散射效果为43％，属于中等状态，903为5阶半雾化状态的光照效果，其介乎于探照光效果和均匀光效果之间的中值，照射角度比图901所示的效果的大，比902所示的小；光照距离比901的小，比902的大；光照强度比901的要小，比902的要大，适合稍远距离的拍摄。同理，可以根据拍摄对象与补光灯的距离通过调整电子遮罩的阶梯调节度，使之光照效果适合拍摄的需求，在此不再赘述。
进一步设计，增加测距模块作为辅助决策模块，控制模块在自动模式的时候，其通过测距模块获得拍摄对象的距离，通过拍摄对象距离查询对应的阶梯调节度，并控制电子遮罩的实现相应的阶梯调节度，使之光照效果适合拍摄的需求，实现自动化补光效果。
通过上述的方式，可以使照明设备根据实际的需求产生对应的光照强度、范围和距离，实现在不同应用场景、不同环境的更好的照明效果，提高了设备的方便性，并大大提高了用户的和使用体验感。
实施例七
本示例通过结合8阶栅格单元构成的电子遮罩对本发明进行说明。
图10为本发明实施例提供的路灯场景下的控制光照范围和光照强度的光照效果对比示意图。增加光强度传感模块和能见度传感模块作为辅助决策模块，控制模块为自动模式。
当其通过光强度传感模块获取环境光的数值低于预设值的时候，控制模块通过控制发光驱动模块使发光模块发光；当控制模块通过光强度传感模块获取环境光的数值高于预设值的时候，控制模块通过控制发光驱动模块使发光模块关闭。
当在能见度较低的夜晚的时候，例如大雾、大雨等天气，控制模块通过光强度传感器获知环境光强度较弱，并通过能见度传感器获取到能见度低的情况，于是控制发光驱动模块使发光模块发光，另外，通过控制遮罩驱动模块使电子遮罩为1阶，透明度为100％，散射效果最小值，1001为路灯的探照光模式，光线形成高亮中心区域，在能见度低的黑夜里可以让行人和司机在很远的地方也能看得见，使人们更容易掌握道路情况。
当能见度较高的夜晚的时候，例如晴天、阴天等天气，控制模块通过光强度传感器获知环境光强度较弱，并通过能见度传感器获取到能见度高的情况，于是控制发光驱动模块使发光模块发光，另外，通过控制遮罩驱动模块使电子遮罩为8阶，透明度为0％，散射效果最大值，1002为路灯的均匀光模式，光线放射角度最大化，光线强度最弱，形成柔和自然的灯光效果，可以让行人和司机如置身于白天一样的均匀光照环境，使人们感受更舒适自然的环境。
当能见度稍低的夜晚的时候，例如小雨、小雾、小雪等天气，或者白天大雨、大雾、大雪等天气，控制模块通过光强度传感器获知环境光强度较弱，并通过能见度传感器获取到能见度较低的情况，于是控制发光驱动模块使发光模块发光，另外，通过控制遮罩驱动模块使由多栅格单元构成的电子遮罩形成内外两圈的两个区域，并控制内圈为3阶，透明度为72％，散射效果为28％；控制外圈为6阶，透明度为28％，散射效果为72％，图1003为路灯的两层光模式，中间区域部分透明度较高，形成亮度较高、角度较小的探照光效果，方便远处的路人和司机看见；***区域部分透明度较低，形成亮度较小、角度较大的均匀光效果，使其适合离路灯较近的路人和司机，使人们感受更舒适自然的环境。
同理，控制模块可以控制多栅格单元构成的电子遮罩各个栅格单元的透明度、不同的几何形状，可以组成***的光照效果，在此不再赘述。
通过上述的方式，可以使照明设备根据实际的需求产生对应的光照强度、范围、距离和光照层次，实现在不同应用场景、不同环境的更好的照明效果，提高了设备的方便性，并大大提高了用户的和使用体验感。
实施例八
本示例通过结合8阶多带状单元构成的电子遮罩对本发明进行说明。
如图11所示，图11为本发明实施例提供的汽车大灯的光照效果示意图，其中，汽车大灯的多带状栅格单元构成的电子遮罩分为下部分1101、中部分1102和上部分1103，汽车照射光程分为近距离1104、稍远距离1105、较远距离1106和远距离1107。
当汽车用近光灯的时候，近光灯的探照灯的范围在近距离1104、稍远距离1105和较远距离1106，并分别对应大灯的下部分1101、中部分1102和上部分1103。当汽车停止或速度很慢(例如，时速5公里/小时)的时候，由于大灯的探照光太强烈，而且比较集中，不利于汽车停止或慢速行驶的视野，于是可以使用慢速模式，即整个电子遮罩为8阶，透明度为0％，散射度为100％，这样光照角度最大，视野最宽阔，明亮度最暗，不会照射对面来的人的眼睛，适合驻车或慢速行驶。当速度较快的适合(例如，时速80公里/小时)，由于车速较快，需要看见较远的地方，因此，整个电子遮罩为1阶，透明度为100％，散射度为0％，这样光照角度最小，明亮度最暗，为探照灯模式。当车速为中等的时候(例如，时速50公里/小时)，这时候介乎于低速和较高速中间，可以调整下部分1101为7阶，中部分1102为4阶，上部分1103为1阶，这样，在较远距离1106为探照灯光效，适合看清远远景，在近距离1104为均匀光光效，适合观察近景，在稍远距离1105则为探照光和均匀光的混合模式，便于驾驶员观察路况。同理，可以根据不同的速度配置各带状电致液晶雾化膜单元的阶梯调节度，使其更适合驾驶员的视觉，在此不再赘述。进一步设计，结合速度传感器，控制模块在自动模式下，可以读取速度传感器的信息，并根据速度传感器获得的实际车速查询相关的调整参数，在通过遮罩驱动模块控制各带状电致液晶雾化膜单元的阶梯调节度，以实现自动配置效果。
当汽车用远光灯的时候，近光灯的探照灯的范围在稍远距离1105、较远距离1106和远距离1107，并分别对应大灯的下部分1101、中部分1102和上部分1103。当汽车在高速行驶的时候(例如，时速120公里/小时)，由于车速非常快，需要看见很远的地方，因此，整个电致液晶雾化薄膜为1阶，透明度为100％，散射度为0％，这样光照角度最小，明亮度最暗，照射距离最远，为探照灯模式，便于司机观察远处景物。当汽车在幽暗路段低速行驶的时候(例如，时速15公里/小时)，由于环境比较暗，需要看见较远的地方，但远光灯会影响来车的视野，于是可以使可以调整下部分1101为1阶，中部分1102为4阶，上部分1103为8阶，这样，在远距离1107为均匀光光效，减少对来车的视觉干扰，在稍远距离1105为均匀光光效，适合观察近景，在较远距离1106则为探照光和均匀光的混合模式，便于驾驶员观察路况。当车速为中等的时候(例如，时速60公里/小时)，这时候介乎于低速和高速中间，同理，可以根据不同的速度配置各带状电致液晶雾化膜单元的阶梯调节度，使其更适合驾驶员的视觉，在此不再赘述。进一步设计，结合速度传 感器，控制模块在自动模式下，可以读取速度传感器的信息，并根据速度传感器获得的实际车速查询相关的调整参数，在通过遮罩驱动模块控制各带状电致液晶雾化膜单元的阶梯调节度，以实现自动配置效果。
通过上述的方式，可以使照明设备根据实际的需求产生对应的距离、分层、强弱，实现在不同应用场景、不同环境的更好的照明效果，提高了设备的方便性，并大大提高了用户的和使用体验感。

当控制模块通过控制遮罩驱动模块使整个电子遮罩为8阶，透明度为0％，散射效果最大值，1202水晶闪耀吊灯的均匀光模式，这时候只能看见外部均匀柔和的灯光，却看不见灯泡或灯珠发光，灯光柔和自然，给人一种现代化的氛围感觉。同理，可以通过控制模块调整整个电子遮罩的阶梯调节度，使其呈现对应的透明状态，使探照光和均匀光的比例适合实际应用环境需求，在此不再赘述。
当控制模块通过控制遮罩驱动模块使整体电子遮罩为8阶，透明度为0％，散射效果最大值，并且，随机让某几个栅格单元为1阶，即透明度为100％，散射效果最小，1203水晶闪耀吊灯的闪耀光模式，这时候只能看见外部整体均匀柔和的灯光，但某几个点却漏出强光的效果；过一阵子后(例如，1秒)，控制器设置上述几个栅格单元为8阶，透明度为0％，散射效果最大值，并随机选择另外几个栅格单元为1阶，即透明度为100％，散射效果最小，如此不断重复运行，则形成闪烁灯光的效果，该效果比传统(静态)水晶灯效果更加漂亮、闪动，给人一种闪耀、高级或魔幻的氛围感觉。同理，可以通过控制模块调整各个子栅格电致液晶雾化膜单元的阶梯调节度，使其呈现其他透明状态，产生不同的闪耀光度、使吊灯呈现更丰富多彩的闪耀、魔幻的氛围效果，在此不再赘述。
进一步设计，灯罩内可以设置多组彩色灯珠群，控制模块通过发光驱动模块控制各彩色灯珠群的亮和灭，配合1203所示的闪耀光模式，有如舞台七彩灯的效果，让灯光效果更加闪耀多彩。通过控制模式的变化可以产生更多的氛围效果和照明效果，在此不再赘述。
通过上述的方式，可以使照明设备根据实际的需求产生对应的光照氛围、色彩搭配、闪耀效果，实现在不同应用场景、不同环境的更好的照明效果，提高了设备的方便性，并大大提高了用户的和使用体验感。

当控制模块通过控制遮罩驱动模块使带状单元构成的电子遮罩为1阶，透明度为100％，散射效果最小值，1301为灯带照明效果示意，可以看见每个LED灯珠发出明亮璀璨的灯光。进一步设计，每个LED灯珠可以单独控制，控制模块通过发光驱动模块控制每个LED灯珠的亮和灭，并产生闪烁的星光效果，犹如仰望璀璨星空的感觉。
当控制模块通过控制遮罩驱动模块使带状单元构成的电子遮罩为8阶，透明度为0％，散射效果最大值，1302为氛围灯照明效果示意，每个LED灯珠发出的灯光被散射出来，形成模糊朦胧的效果。进一步设计，每个LED灯珠可以单独控制，控制模块通过发光驱动模块控制每个LED灯珠的亮和灭，并产生闪烁的氛围灯效果，犹如仰望宇宙银河的感觉。
当控制模块通过控制遮罩驱动模块使带状多栅格单元构成的电子遮罩，控制模块通过控制遮罩驱动模块使整体电子遮罩为8阶，透明度为0％，散射效果最大值，并且，随机让某几个栅格单元为1阶，即透明度为100％，散射效果最小，如图14所示，这时候只能看见外部整体均匀柔和的氛围灯光，并有几个点却 漏出强光的效果；过一阵子后(例如，2秒)，控制器设置上述几个栅格单元为8阶，透明度为0％，散射效果最大值，并随机选择另外几个栅格单元为1阶，即透明度为100％，散射效果最小，如此不断重复运行，则形成闪烁灯光的效果，该效果比传统闪烁灯条效果更加漂亮、闪动，给人一种闪耀、高级或魔幻的氛围感觉，犹如宇宙银河中伴随几个闪烁的星光在闪动的视觉效果。同理，可以通过控制模块调整各个子栅格电致液晶雾化膜单元的阶梯调节度，使其呈现其他透明状态，产生不同的闪耀光度、使吊灯呈现更丰富多彩的闪耀、魔幻的氛围效果，在此不再赘述。
进一步设计，灯带内可以设置多组彩色灯珠群，控制模块通过发光驱动模块控制各彩色灯珠群的亮和灭，配合图14所示的闪耀光模式，让灯光效果更加闪耀多彩。通过控制模式的变化可以产生更多的氛围效果和照明效果，在此不再赘述。
通过上述的方式，可以使照明设备根据实际的需求产生对应的光照氛围、色彩搭配、闪耀效果，实现在不同应用场景、不同环境的更好的照明效果，提高了设备的方便性，并大大提高了用户的和使用体验感。
实施例十一
如图15所示，图15为本发明实施例提供的一种LED灯珠结构示意图。包括LED芯片1501、电子遮罩1502、透镜1503、散热垫1504、LED芯片连接线1505、外封装1506、LED电极1507(图中没有注明与之配对的另外一个LED电极)和电子遮罩电极1508(图中没有注明与之配对的另外一个电子遮罩电极)。其中，电子遮罩1502设置在LED芯片1501的发光面，其位置可以在LED芯片1501和透镜1503之间，也可以在透镜1503外面，视具体生成工艺而定；LED芯片1501和电子遮罩1502有相互独立的供电电极，通过外部通过对LED电极1507进行供电可以控制LED芯片1501的亮和灭，通过对电子遮罩电极1508提供不同的电压控制其的光线散射程度，配合LED芯片1501发出的光线实现不同的光照效果。
进一步设计，可以有多个LED芯片1501构成，可以多个LED芯片1501共用LED电极1507(图中没有注明与之配对的另外一个LED电极)，也可以对每个LED芯片1501单独供电。
再进一步设计，多个LED芯片1501可以添加不同的颜色颜料，使每个灯珠具有不同的颜色，每个LED芯片1501有独立供电，外部电路控制通过发光驱动模块精准控制每个LED芯片1501的亮和灭，从而形成不同的颜色。举个例子，假设有三个LED芯片1501，并颜色分别为红、蓝、绿三原色，于是通过RGB的搭配可以构成各种不同的颜色。
