具体实施方式
下面通过附图和实施例，对本发明的技术方案做进一步的详细描述。
本发明中，使用者的“眼部结构”包括瞳孔、睫状肌和晶状体中的至少一个。本发明中，术语“电力”包括直流电和交流电中的至少一种。本发明中，“时间段”是指一段或多段时间，且本发明的“时间段”意在将具有如下特性的一段或多段时间包括在所要保护的范围内：各段时间的长度可以相同也可以不同，多段时间中各自的时间长度变化可以存在或不存在规律，且多段时间内电力的电气参数可以呈现规律的或不规律的变化。
本发明的显示器发光参数动态调节方法，包括几种不同的技术实现方案，下面逐一进行说明。
在第一个技术方案中，本发明显示器发光参数动态调节方法，显示器具有电源部和与所述电源部对应的动态发光部，在显示器工作期间设置至少一个电气参数变化时间段，包括如下步骤：
步骤1：在每个电气参数变化时间段内具有电源部输出起始电气参数和电源部输出终止电气参数，电源部输出电气参数从所述起始电气参数到所述终止电气参数之间同趋势变化，所述电气参数变化时间段的起始点电气参数和终止点电气参数分别等于该电气参数变化时间段之前和之后的非电气参数变化时间段内的电气参数；以及
步骤2：根据步骤1使动态发光部在所述电气参数变化时间段内改变发光参数，所述发光参数的变化使得使用者眼部结构被动态地改变。
在所述电气参数变化时间段内电气参数的变化对发光参数的改变不足以对视觉感官产生足以察觉的影响正常使用的不利影响。
根据本发明的一些实施例，各个动态发光部改变发光参数包括：在电气参数变化时间段之内，各个动态发光部的发光参数均将发生改变，从而进一步促使使用者的眼睛结构发生更多的变化，获得更多的锻炼。另外，这种变化也使得在不同电气参数变化时间段之间出现发光参数变化或波动较大的情形极大地被减少，从而更有利于使用者在未主观意识到发光参数发生改变的情况下处于发光环境中。更有利地，本发明能够让使用者的眼睛得到更加细致的结构变化，从而使得在使用者眼睛结构上做出适当的和期望的微调成为可能。
根据本发明的一些实施例，所述方法还包括将表征所述电气参数变化方式的信息进行存储的步骤，和/或设置和计数所述电气参数变化频率的步骤。
显示器可以利用动态发光装置实现。下面，进一步结合本发明中包括电源部和动态发光部的动态发光装置的结构，说明实施本发明的动态发光方法的非限制性实例。其中每个电源部可以只控制一个动态发光部，也可以控制多个动态发光部；可以有多个电源部和多个动态发光部。
如图1所示，示意性地示出了本发明的动态发光装置100的电气组成模块框图。该动态发光装置100包括电源部PW和多个动态发光部1，2，...，N，其中N为大于1的自然数。所述电源部PW向所述动态发光部1，2，...，N提供电力。为了清楚起见，图2中并未示出开关这类本领域技术人员应当确定发光装置必然具有的器件。根据本发明的优选实施例，开关设置于电源部PW，其控制是否向多个动态发光部1，2，…，N提供电力，即控制整个动态发光装置100的工作与否。根据本发明的优选实施例，所述动态发光部1，2，…，N属于LED发光装置。
本发明的电源部PW输出的电力的电气参数以预定方式改变。这里的预定方式可以是存储于电源部PW或其他部件中的预先设定的数据表。所述数据表包括多组电气参数。在一些实施例中，这些电气参数可以被通过出厂 前写入存储部的方式被生成。在另一些实施例中，这些电气参数可以被通过该动态发光装置的外部接口(例如USB、网络接口等)被生成或改写。这些电气参数包括但不限于电压和电流中的至少一种。为了简明起见，本发明将针对电压这一参数加以描述，电源部的电路结构如图4所示，其具体描述将在后面给出。这种电力供电方式消除了采用LED发光时通常产生频闪现象的弊端，从而为进入眼睛的光的质量提供了电气方面的保障。
当以预定的方式改变电源部PW输出的电压时，输出到所述各个动态发光部1，2，...，N的电压参数将根据被改变。该电压被用作动态发光部1，2，…，N的发光电压。随着发光电压的改变，所述动态发光部1，2，…，N的发光参数将随之产生变化。
本发明中，发光模式参数包括各动态发光部的照度、光强度、光通量、变化频率、高度、倾斜角度和转动角度中的至少一种。也就是说，当所述发光参数发生变化时，进入使用者眼睛的光的相应参数也将产生改变。这种光的变化使得使用者眼部结构被动态地改变。
当照度、光强度、光通量和角度这些发光参数中的至少一个发生改变时，为了适应上述发光参数的变化，使用者眼睛的虹膜将在使用者无意识的前提下主动调整瞳孔的大小，从而控制光通量。这样，虹膜就跟随发光光的不断变化而运动起来。虹膜的运动会带动睫状肌运动，睫状肌的运动也将带动晶状体的运动，从而产生视觉领域内所谓的“眼睛视光系统三联动”。上述虹膜、睫状肌和晶状体的联动运动将使眼睛的生理结构不断运动，在虹膜、睫状肌和晶状体的形状和/或尺寸上不断地自动改变，使得眼睛的虹膜、睫状肌和晶状体不易凝固在某一个状态下甚至发生视力退化，保持了视光系统的活跃。使用者的眼睛能够根据视物距离调整屈光度，确保视物清晰明亮，达到锻炼使用者眼睛并从根本上控制眼睛近视、远视等问题的产生的目的。同时，眼睛受到上述连续的发光光的改变过程也能够使眼睛适应昼夜环境，对锻炼眼睛避免出现弱视产生作用。

可选地，如图2所示，根据本发明的实施例，所述动态发光装置100还包括多个存储器S。各个存储器S可以是任何种存储介质，包括但不限于：闪存、ROM芯片或任何其他类型的固态非易失性半导体存储器。这些存储器S中设置有与所述各个动态发光部1，2，...，N相对应的发光模式参数。这些发光模式参数被存储于所述存储器8的方式包括例如在制造所述动态发光装置100期间设置发光模式参数到所述存储器8。在另一些实施例中，如果所述动态发光装置100包括与所述存储器8连接且可用于读写所述存储器8的接口(例如红外接口、蓝牙接口、USB接口等，未示出)，则发光模式参数被存储于所述存储器8的方式还包括在所述动态发光装置100被使用期间由专门人员通过该接口修改、删除和/或更新存储器8中的发光模式参数。在另一些实施例中，如果所述动态发光装置100包括与所述存储器8通过无线或有线的方式通信的接口(例如网络接口、红外接口、蓝牙接口、USB接口等，未示出)，则发光模式参数被存储于所述存储器8的方式还包括在所述动态发光装置100被使用期间由使用者自行升级或由所述动态发光装置100的供应商或制造商进行远程升级来修改、删除和/或更新存储器8中的发光模式参数。
可选地，如图2所示，所述动态发光装置100还包括多个计时部T，每个计时部T对应于一个电源部PW并用于设置和计数发光的变化频率。该发光的变化频率为改变所述电力的电气参数的频率。所述计时部T可以是任一种数字或模拟式的计数器、计时器，其计时方式可以是按时间递增或按时间递减的方式完成。所述各个动态发光部1，2，...，N根据至少一个如下参数改变发光参数：发光模式参数、发光的变化频率、电力的电气参数。
根据本发明的一些实施例，表征所述预定方式的信息包括电压、电流、电压和/或电流对应的变化频率，和/或电压或电流的变化步长，其对于动态发光部的驱动方式可以采用PWM(脉宽调制)或者其他方式。这些变化频率可以使用电压或电流变化所对应的时间段或者频率来表征。例如，在一些实施例中，采用多个电压值及其变化时间段表征所述预定方式的信息。此时，如图2所示的电源部PW将采用计数器以电压的变化时间段为计数时间段进行计数，当到达计数终值时采用多个电压值的下一个值，其中所述的多个电压值将被依次地使用。在另一些实施例中，采用电压值和电压步进值：在各个电气参数设定时间段中，每次需要改变如图2所示的电源部PW的输出电压时，就以上一个电气参数设定时间段末尾处的电压值的基础上加上该电压步进值，且此实施例中的电压值和电压步进值可以为一个或多个(当为多个时，可以采用变步长的方式设置电压值)。
根据本发明的一些实施例，所述各个动态发光部的发光参数根据电气参数的改变而改变。例如，在采用电力的电气参数作为发光参数的改变依据时，各个动态发光部将视电压和/或电流和/或电压和/或电流对应的变化频率等改变发光参数。
根据本发明的一些实施例，所述方法进一步包括：在各动态发光部上设置一个或多个发光单元。所述各个动态发光部的所述发光单元根据发光模式参数和/或电力的电气参数改变发光参数。变化原理和方式与上述各个动态发光部根据发光模式参数和/或电力的电气参数改变发光参数的相同。
本发明的电源部PW输出的电力的电气参数以预定方式改变。这里的预定方式可以是存储于电源部PW或其他部件中的预先设定的数据表。所述数据表包括多组电气参数。在一些实施例中，这些电气参数可以被通过出厂前写入存储器的方式被生成。在另一些实施例中，所述动态发光装置具有用于生成或改写这些电气参数的外部接口，此时这些电气参数可以被通过该动态发光装置的外部接口(例如USB、网络接口等，未示出)被生成或 改写。这些电气参数包括但不限于电压和电流中的至少一种。为了简明起见，本发明将针对电压这一参数加以描述，该电源部的电路结构如图4所示，其具体描述将在后面给出。这种供电方式消除了采用LED发光时通常产生频闪现象的弊端，从而为进入眼睛的光的质量提供了电气方面的保障。
当以预定的方式改变电源部PW输出的电压时，输出到所述各个动态发光部1，2，...，N的电压参数将被改变。该电压被用作动态发光部1，2，…，N的发光电压。随着发光电压的改变，所述动态发光部1，2，…，N的发光参数将随之产生变化。根据本发明的另一些实施例，各个动态发光部1，2，...，N中设置有发光单元。根据本发明的优选实施例，这些发光单元采用LED灯珠和/或LED灯条等LED类型的器件。在一些其他的实施例中，这些发光单元也可以采用LED以外的其他类型的光源，例如钨丝灯珠、OLED类型发光器件等。
本发明中各个动态发光部有可能在某一时刻的照度达到最高值10000lux且在另一时刻的照度达到最低值300lux或者是300lux-10000lux之间的任意区间；其中照度在3000K-6000K之间变化或者是其内的任意区间。
进一步地，在该动态发光方法的工作或实施过程中，各个动态发光部在任意时刻的照度均不低于300lux且不高于10000lux。在这种照度的变化(包括上升和/或下降)过程中，即在本动态发光方法的一次实施过程中，照度的上升和下降变化率的绝对值在一定范围内，优选，该范围绝对值在每秒1％-20％内，即照度每0.1秒范围内发光参数的变化范围在大约1.001到1.02之间。
已经普遍接受的事实是人眼视觉暂觉留时间在日间视觉时约为0.02秒，中介视觉时为0.1秒，夜间视觉时为0.2秒，中介视觉是介于日视觉与夜视觉之间的状态。人眼亮度感觉变化滞后于实际亮度变化，以及视觉暂留特性，总称为视觉惰性。通常的发光状况照度在300lux到10000lux 之间，接近中介视觉条件。经过若干次实验，本发明的优选实施例设定0.1秒范围内发光参数的变化范围在大约1.001到1.02之间。在这个变化范围内，发光参数的改变不足以对视觉感官产生足以察觉的影响，但却能使使用者眼睛的虹膜将在使用者无意识的前提下主动调整瞳孔的大小，从而控制光通量。这样，虹膜就跟随发光光的不断变化而运动起来。虹膜的运动会带动睫状肌运动，睫状肌的运动也将带动晶状体的运动，从而产生视觉领域内所谓的“眼睛视光系统三联动”，从而达到锻炼使用者眼睛的目的。
根据所需得到的发光参数来确定控制所述发光参数的电气参数。例如下表1、表2、表3分别是是电气参数变化时间段为10秒、100秒、250秒情况下几组不同初始照度及不同时间点的照度值，表4、表5、表6分别是是电气参数变化时间段为10秒、250秒、250秒情况下几组不同初始照度及不同时间点的照度值，所述照度值变化范围满足：0.1秒范围内发光参数的变化范围在大约1.001到1.02之间。

如图3所示，示出了动态发光装置的另一种电气组成模块框图。包括信号处理单元或数据处理单元(例如MCU)、输入模块、通信接口模块、多个动态发光部1，2，...，n(例如LED光源1，2，...，n)以及与所述动态发光部一一对应的动态发光驱动部1，2，...，n(例如LED驱动1，2，...，n)，还包括电源部。其中，电源部为动态发光装置中的其他模块供电，动 态发光驱动部用于驱动与之对应的动态发光部，所述输入模块用于与接收使用者发出的控制指令或参数调整指令，通信接口模块用于通过有线或无线的方式实现动态发光装置与外部的数据通信，所述动态发光部用于在与之对应的动态发光驱动部的驱动下改变发光参数，所述发光参数的变化使得使用者眼部结构被动态地改变。

图3所示的实施例的工作原理为：电源部将外部输入的电压(例如220V市电)变压为5V和3.3V输出，其中5V电压供给输入模块、通信接口模块和信号处理单元或数据处理单元(例如MCU)以使它们正常工作；3.3V电压供给所述多个动态发光部1，2，...，n(例如LED光源1，2，...，n)以及所述动态发光驱动部1，2，...，n(例如LED驱动1，2，...，n)以使它们正常工作；所述输入模块接收来自使用者向动态发光装置(包括向其组件)发出的控制指令或者参数调整指令并将接收到的信号传输给所述信号处理单元或数据处理单元(例如MCU)，所述通信接口模块将来自动态发光装置外部的指令和/或数据传输到所述信号处理单元或数据处理单元(例如MCU)或者反过来将动态发光装置和/或其内部组件的工作参数或者输入模块向所述信号处理单元或数据处理单元(例如MCU)输入的指令传输到动态发光装置外部；所述信号处理单元或数据处理单元(例如MCU)根据所述输入模块和/或所述通信接口向其传输的指令和/或数据，控制所述动态发光驱动部1，2，...，n(例如LED驱动1，2，...，n)，进而改变所述动态发光驱动部1，2，...，n(例如LED驱动1，2，...，n)向所述动态发光部1，2，...，n(例如LED光源1，2，...，n)发出的驱动信 号(例如电压、电流、脉宽)等，从而使得各个动态发光部相应于所述改变来改变发光参数，所述发光参数的变化使得使用者眼部结构被动态地改变。
根据本发明图1、图2、图3示出的各个动态发光装置的电气组成模块实施例，在调整电力的电气参数，使所述电气参数以预定方式发生改变，以使所述各个动态发光部相应于所述改变来改变发光参数的过程中，电力的电气参数还可选地为电压、电流、频率等中的至少一种，或者采用PWM(脉宽调制)方式连续地改变发光参数。在动态发光期间，也可人工调节发光参数，以适应不同使用者对基础发光参数的要求。
下面结合图4详细介绍多个电源部PW的电路结构。每个电源部PW的输入端连接220V市电，输出产生提供给与之对应的动态发光部1，2，…，或N的电压或电流。电源部PW产生该电压或电流的方式是根据上述电力的电气参数，并受到发光的变化频率的控制。其具体包括两个依次串联的部分：一是电气转换单元，二是信号调理单元。下面将分别给予描述。
在电气转换单元中，包括整流滤波模块和恒流稳压模块；整流滤波模块将电网电压逆变成的24V交流电压变为脉动电压并把脉动电压转化成平滑的电压，恒流稳压模块将滤波模块输出的因电网电压波动引起的不稳定电压转化成相对稳定的电压并为动态发光部1，2，...，N输出恒定的电流。
图4中桥式整流二极管D的a端与c端连接于所述电网电压的两端、b端与d端之间连接滤波电容C1；LM2576-ADJ型开关稳压器TC的1脚与5脚之间连接滤波电容C1、4脚通过电阻R2连接于LM358型集成运算放大器IC的2脚、4脚还连接LM358型集成运算放大器IC的1脚、5脚与4脚之间连接有续流二极管D5、5脚还接地；
由于有时电网电压存在不稳定的情况，在输入的24V交流电压有一定的波动范围，使整流滤波模块输出的电压不稳定，为了获得相对稳定的电压，采用电压可调的LM2576-ADJ型开关稳压器能够使输入不稳定电压能够 稳定输出，由于LM2576-ADJ型开关稳压器的输入电压范围是8～40V，本电路用于驱动3W的动态发光部1，2，...，N时，经过测试可知，当输入电压为13V时，通过负载动态发光部1，2，...，N的电流以及其两端的电压恒定，但由于40V已达到LM2576-ADJ的极限，在极限边缘应用范围稍有变动时器件容易烧毁，因此，本实用新型允许输入电压在13V～38V的范围内波动情况下动态发光部1，2，...，N仍可正常工作，解决了驱动动态发光部1，2，...，N工作的稳压问题。
图4中LM358型集成运算放大器IC的3脚依次通过电阻R1、电容C2、电感L1连接于所述LM358型集成运算放大器IC的2脚，所述LM358型集成运算放大器IC的2脚与4脚之间连接有电阻R3、8脚连接于电容C2的正极。
由于LM2576-ADJ型开关稳压器的2脚输出的稳定电压被负载的动态发光部1，2，...，N和电阻R1分压，当电压达到一定值时，电阻R1允许消耗的功率受限，分到的电压值较小，导致动态发光部1，2，...，N的两端要承受很大的电压从而使电流值很大，采用LM358型运算放大器和电阻R2、电阻R3组成的反馈回路使得电流限定为一恒值，为动态发光部1，2，...，N提供稳定的输入电流，确保了动态发光部1，2，...，N正常稳定工作，具有电路结构简单和很强的实用性。
根据本发明的优选实施例，发光单元产生频率为1000-3000Hz的光。该范围内的光是人的敏感频率。在发光过程中，对学习和读书有放松作用。
根据本发明的另一些实施例，各个动态发光部1，2，...，N分别设置有至少一个发光单元。根据本发明的一个实施例，这些发光单元采用LED灯珠和/或LED灯条等LED类型的器件。在一些其他的实施例中，这些发光单元也可以采用LED以外的其他类型的光源，例如钨丝灯珠、OLED类型发光器件等。一个实施例中，动态发光部上的灯珠被以多排交错的样式布置于呈平面的动态发光部的至少一个表面。发光单元的布置方式不限于此， 例如，根据本发明的另一些实施例，发光单元可以被布置在呈立体曲面样式的动态发光部的至少一个表面。
根据本发明的优选的实施例，各个动态发光部1，2，…，N之一分别对应于图6中的一个或多个任意排列的多个发光单元的组合。根据示意性但非限制性的描述，这些组合例如包括：各个动态发光部1，2，…，N分别对应于一行发光单元；或者各个动态发光部1，2，…，N分别对应于各行发光单元中的前一行中的一个或多个以及相邻行中的一个或多个。
对于各个动态发光部，其中某一个的发光单元的照射方向中心线可以被设置成与其他发光单元的照射方向中心线呈一定角度。根据本发明的另一些实施例，如果各个动态发光部的至少一个可以具有彼此呈一定角度的两个表面，则当设置发光单元于上述动态发光部时，位于上述两个表面上的发光单元的发光方向将彼此不同。
根据本发明的一些实施例，所述发光单元根据至少一个如下参数连续地改变发光参数：发光模式参数、发光的变化频率、电力的电气参数。其中，电力的电气参数不直接作用于发光单元，而是通过作用于电源部PW产生的电压或电流而间接地作用到发光单元；发光模式参数的改变通过发光单元的类型、型号的选取和/或发光单元受到的电压或电流的作用而实现；发光的变化频率通过上述存储器S中存储的变化时间而设置。
根据本发明的优选实施例，所述动态发光装置100还包括支撑部，所述多个动态发光部1，2，...，N被设置于所述支撑部上且根据预设的发光模式参数沿所述支撑部的延伸方向移动和/或绕所述支撑部转动。这种移动和转动使动态发光部1，2，…，N照射到使用者的阅读对象时产生彼此的叠加、减弱和角度等组合变化。其中角度的变化根据设置发光单元的动态发光部的形状和结构，以及发光模式参数在不同时刻或按照上述发光的变化频率产生的改变而变化。根据本发明的优选实施例，上述移动的速度小于1mm/s，转动的角速度小于5°/s。

在第二个技术方案中，本发明的显示器发光参数动态调节方法，显示器具有电源部和与所述电源部对应的发光部，在显示器工作期间包括多个电气参数变化时间段和至少一个非电气参数变化时间段，包括如下步骤：
步骤1：在每个电气参数变化时间段内具有电源部输出起始电气参数和电源部输出终止电气参数，电源部输出电气参数从所述起始电气参数到所述终止电气参数之间呈同趋势变化，相邻电气参数变化时间段内电气参数变化 趋势相同或不同；

根据本发明的一些实施例，所述方法还包括将表征所述电气参数变化方式的信息进行存储的步骤，和/或设置和计数所述电气参数变化频率的步骤。
同样的，显示器可以利用动态发光装置实现。本发明中包括电源部和动态照明部的动态照明装置的结构与上述实施例相同，具体参见图1-图14，此处不再展开重复，区别在于，在照明期间电源部输出包括至少一个电气参数变化时间段和至少一个非电气参数变化时间段。
因此根据本发明的电气参数随时间变化的波形图示例如图16所示，当然，符合本发明构思的电气参数随时间变化的波形图并不仅限于该图所示。
本发明中的电气参数也可以通过设定电气参数变化率来改变，所述电气参数的变化率根据照明参数的变化率来确定。
在动态发光期间，可人工调节发光参数，使得当前发光变明或变暗，以适应不同使用者的发光需求。
本发明还保护使用本发明发光方法的显示装置。本发明还保护使用本发明发光方法的发光装置，例如本发明的动态发光方式可应用于台灯或家用发光灯。
在第三个技术方案中，提供了显示器发光参数动态调节方法，所述显示器具有电源部和与所述电源部对应的动态发光部，在显示器工作期间包括C个电气参数设定时间段，其中C大于等于2，包括如下步骤：
步骤1：在两个相邻的电气参数设定时间段分别设置不同的电源部输出的电气参数，以及
步骤2：根据步骤1所述电气参数，使动态发光部动态地改变发光参数，所述发光参数的变化使得使用者眼部结构被动态地改变。
根据本发明的一些实施例，各个动态发光部改变发光参数包括：在电气参数变化时间段之内，各个动态发光部的发光参数均将发生改变，从而进一步促使使用者的眼睛结构发生更多的变化，获得更多的锻炼。另外，这种变化也使得在不同电气参数变化时间段之间出现发光参数变化或波动较大的情形极大地被减少，从而更有利于使用者在未主观意识到发光参数发生改变的情况下处于发光环境中。更有利地，本发明能够让使用者的眼睛得到更加细致的结构变化，从而使得在使用者眼睛结构上做出适当的和期望的微调成为可能。
根据本发明的一些实施例，所述方法还包括将表征所述电气参数变化方式的信息进行存储的步骤，和/或设置和计数所述电气参数变化频率的步骤。
同样的，显示器可以利用动态发光装置实现，本发明中包括电源部和动态照明部的动态照明装置的结构与上述实施例相同，具体参见图1-图14，此处不再展开重复，但与前两个方案相比，其电气参数的设定不同，变化不同。此处着重对于区别之处进行描述。
结合图2，根据本发明的一些实施例，所述方法进一步包括：在各动态照明部上设置一个或多个发光单元。此时，所述各个动态照明部根据照明模式参数和/或电力的电气参数改变照明参数进一步包括：所述各个动态照明部的所述发光单元根据照明模式参数和/或电力的电气参数改变照明参数。变化原理和方式与上述各个动态照明部根据照明模式参数和/或电力的电气参数改变照明参数的相同。
本发明的电源部PW输出的电力的电气参数以预定方式改变。这里的预定方式可以是存储于电源部PW或其他部件中的预先设定的数据表。所述数据表包括多组电气参数。在一些实施例中，这些电气参数可以被通过出厂前写入存储器的方式被生成。在另一些实施例中，所述动态照明装置具有用于生成或改写这些电气参数的外部接口，此时这些电气参数可以被通过该动态照明装置的外部接口(例如USB、网络接口等，未示出)被生成或改写。这些电气参数包括但不限于电压和电流中的至少一种。为了简明起见，本发明将针对电压这一参数加以描述，该电源部的电路结构如图4所示，其具体描述将在后面给出。这种供电方式消除了采用LED照明时通常产生频闪现象的弊端，从而为进入眼睛的光的质量提供了电气方面的保障。
当以预定的方式改变电源部PW输出的电压时，输出到所述各个动态照明部1，2，...，N的电压参数将被改变。该电压被用作动态照明部1，2，…，N的照明电压。随着照明电压的改变，所述动态照明部1，2，…，N的照明参数将随之产生变化。区别于现有技术中通过数字信号技术进行信号调理的方式，本发明优选采用模拟的方式产生上述照明电压。这样，提供给动态照明部1，2，…，N的照明电压的变化在时域上将是平滑的。于是，所述动态照明部1，2，…，N发出的光的照明参数将产生连续的变化。
根据本发明的另一些实施例，各个动态照明部1，2，...，N中的设置有发光单元。根据本发明的优选实施例，这些发光单元采用LED灯珠和/或LED灯条等LED类型的器件。在一些其他的实施例中，这些发光单元也 可以采用LED以外的其他类型的光源，例如钨丝灯珠、OLED类型照明器件等。
本发明中各个动态照明部有可能在某一时刻的照度达到最高值10000lux且在另一时刻的照度达到最低值300lux或者是300lux-10000lux之间的任意区间；其中照度在3000K-6000K之间变化或者是其内的任意区间。
对于不同的环境亮度B。人眼可觉察的最小亮度差D Bmin/B是相同的，并等于一个常数。换句话说，人眼亮度感觉的增量D S不是正比于客观亮度的增量D B，而是正比于亮度的相对增量D B/B，根据韦伯费赫涅尔定律，主观亮度感觉与客观亮度的对数成线性关系。ξ＝D Bmin/B称为对比度灵敏度阈或韦伯－费赫涅尔系数(Weber－FecnerRatio)。通常ξ＝0.005～0.02，在亮很高或很低时，ξ增大至0.05，而且对于不同人群，其对比度灵敏度阈也不同。以6-18岁青少年为例，其对比度灵敏度阈大致为0.01。.基于此，本发明的相邻电气参数变化时间段之间的照明参数变化率保持在0.02以内(含)，以保证人眼对照明参数的变化无明显察觉，从而不影响正常工作和学习，却能使使用者眼睛的虹膜将在使用者无意识的前提下主动调整瞳孔的大小，从而控制光通量。这样，虹膜就跟随照明光的不断变化而运动起来。虹膜的运动会带动睫状肌运动，睫状肌的运动也将带动晶状体的运动，从而产生视觉领域内所谓的“眼睛视光系统三联动”，从而达到锻炼使用者眼睛的目的。
本发明的电器参数设定时间段优选为0.1秒至5分钟之间。
下面举几个非限制性例子。
例1
第一电气参数设定时间段时长为0.1秒，期间照度值为3000，与之相邻的第二电气参数设定时间段时长为5秒，期间照度值为3055，与之相邻的第三电气参数设定时间段时长为2秒，期间照度值为3100，与之相邻的 第四电气参数设定时间段时长为5分钟，期间照度值为3040。
