具体实施方式
本实用新型 较佳实施例的 基于光敏元件的自动照明装置原理 如图1所示 ，包括控制模块 20 ，还包括电连接在控制模块 20 输入端的光敏元件 10 、以及电连接在控制模块 20 输出端的功率可控的电发光器件 30 。其中，光敏元件 10 用于获取自动照明装置所在的当前环境照度值；控制模块 20 用于接收该当前环境照度值，并根据当前环境照度值向电发光器件 30 发送功率控制信号，以调节电发光器件 30 的输出功率；电发光器件 30 用于接收该功率控制信号，并根据功率控制信号自动调节输出功率，以使得当前环境照度值适当 。在当前环境中同时有多个照明装置使用时，其中一个或几个灯具熄灭，当前环境照度值改变，则上述自动照明装置会自动感应到环境照度的变化，从而及时做出反应，将输出功率调整到合适的值，以保证当前环境的整体亮度。
优选地，上述实施例的自动照明 装置 中，如图2所示， 控制模块20包括顺次连接的接收单元21、阈值比较单元22和信号输出单元23。其中，控制模块20所输出的 功率控制信号包括表示 当前环境照度过大的第一信号、表示当前环境照度适当的第二信号和表示当前环境照度过小的第三信号。请同时参阅图2和图3，接收单元21 执行步骤 S301 ， 用于接收 当前环境照度值 ；阈值比较单元22执行步骤S302，用于将当前环境照度值与预先设置的表示合理环境光线强度的照度阈值相比较，并执行步骤S303、S304和S305，在当前环境照度值大于照度阈值时，产生第一信号，在当前环境照度值等于照度阈值时，产生第二信号，在当前环境照度值小于照度阈值时，产生第三信号；信号输出单元23执行步骤S306、S307和S308，用于向 电发光器件 30 输出该第一信号、第二信号和第三信号。
本实施例中，功率可调的电发光器件30可根据第一信号、第二信号和第三信号来实现输出功率的定性范围调节，如电发光器件30收到的是第一信号，则适当调低输出功率，以减小当前环境照度，以免产生眩光，如电发光器件30收到的是第二信号，则认为当前照度合适，不调整输出功率，如电发光器件30收到的是第三信号，则适当调高输出功率，以提高当前环境照度，以免弱光伤害眼睛。如果电发光器件30的输出功率一次调节不到位，则照明装置会自动根据此判断多次调节，直到最终当前照度合适。
在更加优选的实施例中， 控制模块20所输出的功率控制信号还包括表示当前环境照度值与照度阈值相比较后的差值信息。同时参阅图2和图4，接收单元21执行步骤S401，用于接收当前环境照度值；阈值比较单元22执行步骤S402，用于将当前环境照度值与预先设置的表示合理环境光线强度的照度阈值相比较，并得到当前环境照度值与照度阈值的差值信息，并执行步骤S403、S404和S405，在当前环境照度值大于照度阈值时，产生第一信号，在当前环境照度值等于照度阈值时，产生第二信号，在当前环境照度值小于照度阈值时，产生第三信号；信号输出单元23执行步骤S406、S407和S408，用于向 电发光器件 30 输出该第一信号、第二信号和第三信号，以及上述差值信息；电发光器件30则接收第一信号、第二信号或第三信号，并结合差值信息来调节 输出功率，以使得 当前环境照度值与照度阈值相等或近似于相等。这样可保证电发光器件30能快速准确的将输出功率调节到位，而不需要多次反复调节。
在进一步的实施例中，如图2所示， 自动照明装置中的 控制模块20还包括连接阈值比较单元22的阈值设置单元24，用于根据不同用户需求设置需要的照度阈值 。由于在不同的使用环境中对照度的要求不同，例如看书、夜灯照明等，因此用户可根据不同的需求来设置照度阈值可使得自动照明装置更加智能，如果用户不了解什么环境下多大的照度值才是合适的，可将该阈值设置单元24设置为档位开关，不同档位对应不同的使用环境，以方便用户使用。
在更进一步的实施例中，如图1所示，上述 自动照明装置 还包括 电连接在控制模块 20 输出端的指示元件 31 ，该指示元件 31 用于根据第一信号、第二信号或第三信号分别指示当前环境照度过大、适当或过小 。其中，指示元件31可以是通过不同颜色显示来指示 当前环境照度过大、适当或过小的 三色发光二极管，例如照度过大显示红色，适当显示绿色，过小则显示蓝色；也可以是通过不同声音来提示 当前环境照度过大、适当或过小的音效输出装置，可以事先在该音效输出装置中预存提示音；或者是其他能提示用户的装置 。在自动照明装置刚启动时，该指示元件会指示当前环境照度情况，自动照明装置会自动调节输出功率，直到指示元件31指示的当前环境照度为适当为止。如果指示元件31长时间无法指示到适当，则该自动照明装置可能是出现了故障，可以送去维修。
在更进一步的实施例中，如图 5 所示，上述自动照明装置 还包括安装有电发光器件30的支撑架50和连接支撑架50以便于固定的座体60，当然还会包括其他必须组件，如灯壳40等，其中光敏元件10、控制模块20及发光器件30同时设置在支撑架50顶端，以便于光敏元件10能准确测量被照物周围的环境照度。例如在看书时，光敏元件10可以以电发光器件30的位置为基准点，准确测量书本70表面的照度。
优选地，上述实施例中，如图5所示，支撑架50可弯折，使用者可以通过调整支撑架50的弯折程度来改变被照物（如图5中的书本70）周围的环境照度，这样也可以达到一定的节能效果。
其中，上述各实施例中，光敏元件10优选采用光敏电阻或光敏二极管或光敏三极管，以便于安装在 自动照明装置 上。
可以理解，本实用新型上述各实施例中的自动照明装置并不限于附图5中所示的结构，可以是能实现上面所描述功率自动调节原理的任意结构。
如图6所示，在本发明的另外一则实施例中，控制模块20的输入端还电连接一个误触发判定单元， 用于判定光敏元件接收的当前环境照度值是否为误触发的信号。当误触发判定单元对于光敏元件 10 探测的环境亮度是否测量准确，避免出现由于光敏元件 10 的测量错误引起的电发光器件 30 的错误调节。
优选的，误触发判定单元为光敏电阻或 光敏二极管或光敏三极管。
优选的，误触发判定单元探测的亮度区域与光敏元件10所探测的区域不相同。
基于图6的自动照明装置，提供一种如图7所示的 自动照明装置控制流程图。步骤 S701 ）光敏元件 10 接受当前环境照度值，并将该照度值发送至控制模块；步骤 S702 ）控制模块 20 中的接收单元 21 接收光敏元件 10 所探测的环境照度值，并发送至阈值比较单元 22 ，进行与照度阈值的比较，并在当前环境照度值大于照度阈值时进入步骤 S703 ，在当前环境照度值等于照度阈值时，进入步骤 S704 ，在当前环境照度值小于照度阈值时，进入步骤 S705 ；步骤 S703 ）在当前环境照度值大于照度阈值时，产生第一信号；步骤 S704 ）在当前环境照度值等于照度阈值时，产生第二信号；步骤 S705 ）在当前环境照度值小于照度阈值时，产生第三信号；在步骤 S703 、 S704 、 S705 后，误触发判定单元对环境亮度进行分析，分析结果与光敏元件 10 的探测结果进行比较，若比较的结果为相同，则表明没有发生误触发，由信号输出单元 23 输出各信号，否则在比较结果不同的时候，判断发生误触发，返回步骤 S701 ，且不输出第一信号或第二信号或第三信号。
在图 8 所示的实施例中，自动照明装置还包括误触发判定单元 80 ，误触发判定单元 80 用于判定光敏元件 10 对于使用环境的亮度探测有无错误，以提高照明装置的准确性。光敏元件 10 对于环境亮度进行探测后与阈值进行比较，并根据比较结果产生第一信号或第二信号或第三信号。误触发判定单元 80 对于环境亮度进行探测，所探测的区域与光敏元件 10 的探测区域不相同。当误触发判定单元 80 所探测的环境亮度与光敏元件 10 的探测相吻合的时候，判定不存在误触发，电发光器件 30 根据相应型号进行亮度调整；否则在当误触发判定单元 80 所探测的环境亮度与光敏元件 10 的探测不吻合的时候，判定存在误触发，光敏元件 10 重新对环境亮度进行探测。
优选的，光敏元件装置在可转动平台上，平台转动时带动光敏元件探测不同位置的环境亮度。
综上所述，本实用新型通过采用光敏元件 10 获取自动照明装置所在的当前环境照度值，并通过控制模块 20 来根据当前环境照度值来控制电发光器件 30 输出功率的调节，以使得当前环境照度值适当。这样可以实现照明装置的照度自动化调节，使用起来非常方便，而且能保证照明装置的照度合适，不会伤害使用者的眼睛，并可达到节能的目的。
应当理解的是，对本领域普通技术人员来说，可以根据上述说明加以改进或变换，而所有这些改进和变换都应属于本实用新型所附权利要求的保护范围。
