Description

一种自适应亮度调节电路及内红点瞄具 技术领域
本发明涉及一种自适应亮度调节电路及内红点瞄具。
背景技术
现有内红点瞄具中的一种，即LED灯模组安装在瞄具内芯腔室内壁上的内红点瞄具，其具有可隐藏LED灯模组出射光的特性，尤其是具有太阳能电池供电的此种内红点模组，其更可以借助阳光为LED灯模组供电，从而节约电池电能，同时还可以根据接收到的阳光的强弱自适应调节LED灯的出射光的亮度，无需手动调节，但是此种借助天阳能发电本身特性调节LED灯出射亮度或强弱的供电方式，存在一个非常明显的缺陷，即当瞄具所处环境光与目标物本身的光照或所处环境不一致且具有较强差异时，比如，当瞄具处于室内，而目标物处于室外的阳光照射下时，LED灯发出的光斑的强度不能适应处于强光环境中的目标所需要的亮度，从而导致产生的内红点亮度微弱，造成瞄准吃力，甚至几乎失效。
同样，当射击者处在明亮处射击黑暗环境中的目标时，仅仅依靠前述的采集目标物或目标物周边的光照度来实现对LED亮度的调节则会使得射击者的体验变差，甚至会因为LED亮度的减弱引起射击者的不适和反感。
发明内容
本发明的目的是克服现有的太阳能内红点瞄具所存在的不能适应目标物本身或其所处环境的光照强度，尤其是当目标物处于强光环境中时不能产生与目标物所处环境的光强适应的内红点而导致瞄准吃力、甚至失效的问题，同时兼顾射击较昏暗的环境中的目标时射击者舒适感。使得射击者获得与瞄准目标位置环境光匹配的LED亮度，减少以往单传感器造成的误判及繁琐的操作。
为达上述目的，本发明提供了一种太阳能内红点瞄具，包括设置在本体上的供电电池、太阳能电池、设置在本体上或本体内的控制电路板和LED发光芯片，其特征在于：还包括用以采集射击目标或该射击目标周边的光照度信号的光电传感器；
所述供电电池与太阳能电池组成双电源供电电路；
所述太阳能电池与所述光电传感器组成双传感器采样电路；
所述双电源供电电路通过控制电路板共同驱动LED发光芯片，并且控制电路板根据所述双传感器采样电路在不同环境下的光照度信号来控制所述双电源供电电路给所述LED发光芯片提供合适的供电，从而使得该LED发光芯片获取与所述光照度适应的电能，从而提供清晰、适度的亮光照度，以确保射击精度；
所述光电传感器与所述LED发光芯片设置在同一基座上,且该光电传感器置于所述LED发光芯片的一侧，并在除以上所述功能外，还可以组成一组光电收发器件，通过外部光电收发器对内红点瞄具的功能进行设置。
本发明的优点是：结构简单，能够根据目标物自身及其所处环境的光照自适应调节LED灯的亮度，尤其是可以兼顾太阳能电板反应的射击者所处的环境，综合获取LED的工作电能，使其工作在最佳，出射亮度满足清晰瞄准辅助的需要，无需手动调节锂电池供电，简化操作，同时可以很好的节约锂电池电能。

具体实施方式
图1、2所示为一种太阳能内红点瞄具，包括设置在本体1上的电源、太阳能电池2、设置在本体1上或本体1内的控制电路板和LED发光芯片4，还包括设置在LED发光芯片4一侧(图1所示为开放式内红点瞄具,包括安装在本体1顶部前端的透镜安装架7，LED发光芯片4安装在本体1后端端部3，)光电传感器5(或称为光照度传感器，用以检测光照的强度信号)，该光电传感器5用以采集射击目标或该射击目标周边的光照度信号以及太阳能电池2采集的内红点瞄具所处的环境光照度信号；控制电路板根据双传感器的光照度信号以获取提供给LED发光芯片4所需的 电能，并将该电能与太阳能电池2提供的太阳能电能进行比较，以在太阳能电池电能小于所述电能时，控制电路板控制电池供电驱动电路以给LED发光芯片4进行补偿性供电，从而使得该LED发光芯片4获取足够的电能工作，即通过电池给LED发光芯片4提供的电能量为控制电路板根据双传感器的光照度信号产生的应该给LED发光芯片4提供的电能量与太阳能电池2提供的太阳能电能量间的差值，从而确保LED发光芯片4有足够的电能正常工作。或在太阳能信号较强时，仅通过控制太阳能电池供电驱动电路给LED发光芯片4供电。通过此种电路结构,可以确保LED发光芯片4的亮度处于清晰照射射击目标,即与射击目标反射或其所处环境光强相适应，从而提供清晰、明亮的红点指示,即不管射击目标所处的环境的光强如何,始终保持内红点亮度较强于射击目标或者目标所处环境光线,从而为使用者提供明亮、显眼的光点指示,利于精准瞄准。
而当射击处于比较昏暗的环境中的目标时，为了确保射击者的舒适感，本实施例特别将太阳能电池2和光电传感器作为传感器使用，通过控制电路板采集太阳能电池2和光电传感器的光照度信号，从而有效避免因为仅仅依靠单一光照度传感器导致的LED供电电能偏大或者偏小，使得LED发出的光与目标环境光不协调问题。
而图3、4所示为另一种管式具有太阳能电池辅助供电的内红点瞄具内芯示意图，借助本体1和内芯6的遮挡有效虑除或减弱内红点瞄具所处环境的光干扰,更多的获取射击目标的反射光强或其所处环境的光强，(即该内红点瞄具包括安装在本体1内的内芯6，光电传感器5和LED发光芯片4均安装在内芯6的内壁，其中，光电传感器5和LED发光芯片4安装在内芯6内的LED基座8上)，其在内芯6内壁的LED芯片的附近安装PD即光电传感器，用以检测进入芯管内的目标物反射光或目标物附近的环境光的强度，并传输给MCU，以与太阳能电池的供电信号比对。从而实现同样的控制功能。
在本实施例中，将光电传感器、LED发光芯片集成在一块电路板上，且安装在图3所示瞄具的内芯2的内腔表面或图1所示的底座后端的LED芯片安装架上，这样就使得光电传感器受瞄具本身所处环境的光照的影响就很小，更多的接收来自目标物本身或其周边的环境光，从而满足自适应与目标物适配的LED灯光照的设计目标。
如图5、6、7、8、9所示，即一种基于目标物的自适应亮度调节电路，包括LED光源(LED发光芯片)、MCU、光照度传感器(光电传感器)、太阳能电池、太阳能电池供电驱动电路、供电电池和电池供电驱动电路；光照度传感器通过信号放大电路将采集的目标物反射光或目标物周边的环境光的光照度信号传输给MCU；太阳能电池供电驱动电路与LED光源连接；供电电池通过MCU及电池供电驱动电路与LED光源连接；太阳能电池除了发电同时将信号传递给MCU，MCU通过判断太阳能电池信号强弱来控制太阳能电池供电驱动电路给LED光源提供的电能大小；MCU将 双传感器信号进行比较，以控制双驱动电路给LED光源供电，从而始终确保所述LED光源的亮度处于较强的状态。
如此一来，通过光电传感器采样瞄准目标物本身的或其附近的环境光的强度与瞄具所处环境的太阳能电池的采样信号进行比较，来控制太阳能电池驱动电路及电池供电驱动电路工作，可以始终确保LED灯的出射光维持较高的亮度，非常利于辅助瞄准。
图5所示为太阳能供电驱动电路，其通过GDC_AN1传输采样信号给图9所示的型号为PIC16F1508的MCU及周边电路，而光电传感器的信号经图8所示的信号放大电路进行滤波、放大处理后传给MUC，MCU将该信号与太阳能电池的信号比较后，通过图6所示的太阳能电池驱动电路及供电电池驱动电路给LED光源进行补偿性供电。图7所示为电池供电驱动电路及按键控制档位电路。
结合图10，可知一种基于目标物及环境光的自适应亮度调节电路，包括LED发光芯片4、MCU、按键、太阳能电池2、光电传感器5、太阳能电池供电驱动电路、供电电池和电池供电驱动电路；光电传感器5通过信号放大电路将采集的目标物反射光或目标物周边的环境光的光照度信号传输给MCU；太阳能电池2通过太阳能电池驱动电路与所述LED发光芯片连接；供电电池通过所述MCU经电池供电驱动电路与LED发光芯片连接。
该电路中太阳能电池与光电传感器组成双传感器；太阳能电池2与供电电池组成双电源；太阳能电池驱动电路与电池供电驱动电路组成双驱动电路；通过MCU控制以实现以下功能。
1)、当双传感器提供给MCU均为强信号时，则MCU主要通过控制太阳能电池驱动电路从太阳能电池(2)取电以提供给所述LED发光芯片(4)发光所需的电能，从而满足射击目标环境需要的光标照射亮度；
2)、当双传感器提供给MCU均为弱信号时，则MCU主要通过控制电池供电驱动电路从供电电池取电以提供给所述LED发光芯片(4)发光所需的电能，从而满足射击目标环境需要的光标照射亮度；
3)、当光电传感器(4)信号强于所述太阳能电池(2)信号时，则MCU通过控制双驱动电路从双电源取电以提供给所述LED发光芯片(4)发光所需的电能，并且当LED发光芯片(4)所需的电能大于所述太阳能电池的供电电能时，所述MCU通过电池供电驱动电路从所述供电电池进行电能补充，得到清晰、适度的亮光照度，从而满足射击目标环境需要的光标照射亮度。
4)、当光电传感器(4)信号弱于所述太阳能电池(2)信号时，则MCU通过控制双驱动电路从双电源取电以提供给所述LED发光芯片(4)发光所需的电能，并且根据双传感器信号的差值，合理匹配提供给所述LED发光芯片(4)发光所需的电能，得到清晰、适度的亮光照度，从而满足 射击目标环境需要的光标照射亮度。
综上，不难看出，本实施例提供的一种太阳能内红点瞄具，为了使得射击精度更与目标本身或目标所处环境更为接近的环境光照度为参考依据，给LED提供适应的供电电能，特由供电电池与太阳能电池2组成双电源供电电路；太阳能电池2与所述光电传感器5组成双传感器采样电路；其中，双电源供电电路通过控制电路板共同驱动LED发光芯片4，并且控制电路板根据双传感器采样电路在不同环境下的光照度信号来控制双电源供电电路给所述LED发光芯片4提供合适的供电，从而使得该LED发光芯片4获取与光照度适应的电能，从而提供清晰、适度的亮光照度，以确保射击精度。
另外，本实施例提供的控制电路板还可根据光电传感器5采集到的光照信号如采集图11中所示的外部LED光照信号给控制电路板,控制电路板根据光电传感器5采集到的外部LED的光照信号控制LED发光芯片4发出光信号，以实现不同设定方式或目的的通信信号的传递和控制，如可以根据获取的外界光信号设置瞄具的定时关机时间功能，还可以根据光电传感器5采集到的光照信号，如采集的光电收发器或光照单发射器(如照明灯)或手机光源即LED灯的光照，实现调整内红点LED(即LED发光芯片4)亮度参数的系数；不同的客户对同一环境亮度下，需求不同内红点LED的亮度，从而满足有的客户需要亮一些，有的客户需要弱一些的实际需求。
以上两种不同的通信的实现方式是：把手机闪光灯对准内壳的后端内侧传感器即光电传感器5,利用手机上的APP软件，调节闪光灯的闪烁频率变化，如闪光灯闪烁30HZ 5s，再闪烁15HZ 5S，表示提高一档自动关机时间，自动关机时间有以前的3小时，变更为4小时；此时，内红点LED每间隔1s快速闪烁4下；闪光灯闪烁30HZ 5s，再闪烁10HZ 5S，表示提高一档自动关机时间，自动关机时间有以前的3小时，变更为1小时；此时，内红点LED每间隔1s快速闪烁2下。这些功能的实现主要依靠软件程序实现。以及在夜间使用时，光电传感器5同时可以监测对向使用红外光照射己方，实现预警提示功能。
