在应对不同种类的食物中，所采用的发光方案并不相同，其中，对于水产类的照明中，本具体实施例还提供可以提升水产类食物的新鲜程度的方案。
参考图31至图34，提供了一种发光装置，所述发光装置发出白光，其中，所述白光的光谱曲线具有三个特征，这里称为光谱特征。光谱特征指的是在光谱曲线中具有特殊走向的曲线特征。为了便于描述三个特征分别称为第一光谱特征、第二光谱特征和第三光谱特征。
其中，在这三个光谱特征中，所述第一光谱特征具有第一波峰，其中，第一波峰出现在380nm-470nm的波长范围中。
第二光谱特征具有第二波峰，其中，第二波峰出现在470nm-590nm的波长范围中。第三光谱特征具有第三波峰，其中，第三波峰出现在590nm-780nm的波长范围内。
对于三个波峰的光谱强度关系，如果将第三波峰的光谱强度设置为1，那么，在本具体实施例中，即第三波峰的峰值处的光谱强度为1。第一波峰的峰值处的光谱强度为0.74至1，第二波峰的峰值处的光谱强度为0.84至1.1。从三个波峰的光谱强度来看，整个白光的光谱曲线呈现为两个高峰，一个次高峰的形态。
通过实验发现，本发光装置可以在保证白光，照明真实性的前提下实现提升水产类物品的视觉新鲜程度的目标。从而可以吸引消费者的目光，提升消费者的购买欲望。
在一些进一步的具体实施例中，对于本发光装置所发出的白光，其的相关色温在5000K至6500K的范围内。对于水产类物品的视觉新鲜程度的提升效果具有较高的贡献。
在一些进一步的具体实施例中，在对于水产类物品的视觉新鲜程度的提升效果比较好的白光光谱中，对于三个波峰的峰值波长进行研究和筛选发现。当第一波峰的峰值波长为444nm，第二波峰的峰值波长在496nm至497nm的波长范围内。第三波峰的峰值波长在623nm至624nm的波长范围内。此时的白光光谱作用在水产类物品中，对于视觉新鲜程度的提升，要相对于其他峰值波长范围贡献程度较高。
同时，在一些进一步的具体实施例中，对于三个波峰半峰宽的进行研究和筛选发现。当第一波峰的半峰宽的范围为20nm至21nm，第二波峰的半峰宽的范围为34nm至41nm，第三波峰的半峰宽的范围为21nm。此时的白光光谱作用在水产类物品中，对于视觉新鲜程度的提升，相对于其他半峰宽的范围具有较高的贡献。
在对于水产类物品的视觉新鲜程度提升效果贡献较大的白光光谱进行参数Rg分析发现，当白光的Rg＞100时，对于水产类物品的视觉新鲜程度的提升，具有较大的贡献。特别是在白光中的Rgcs,h9参数，Rgcs,h10参数，对于视觉新鲜感有较为重要的作用。对于Rgcs,h9参数和Rgcs,h10参数的进一步研究发现，Rgcs,h9参数和Rgcs,h10参数在一定的范围内，对于水产类物品的视觉新鲜感的提升效果最佳。其中，对于Rgcs,h9参数所要求的范围为：Rgcs,h9参数应不小于16％。对于Rgcs,h10参数所要求的范围为：Rgcs,h10参数应不小于7％。
在对于水产类物品的视觉新鲜程度提升效果功效较大的白光光谱进行Duv研究发现，基于相同的色温、色容差、Rg、Rf，不同的Duv会影响水产类物品的新鲜感，在黑体辐射曲线轨迹上(即Duv＝0)以及在黑体辐射曲线轨迹下方区域(即Duv＜0)效果最佳。即，白光的色坐标位于CIE1931-xy色品图中的黑体辐射曲线轨迹或者其的下方区域。
在一些进一步的具体实施例中，白光的色容差＜5SDCM。其中，色容差是指电脑计算的配方与目标标准的相差，以单一照明光源下计算，数值愈小，准确度则愈高。但是要注意，它只代表某一光源下的颜色比较，未能检测于不同光源下的偏差。光源发出的光谱与标准光谱之间的差别。在一些进一步的具体实施例中，白光的Rf≥80。

照明灯具在对于生鲜食品的照明过程中，一般都是将特定的照明灯具放置在特定的食品放置区中。但是，当物体改变的时候，照明灯具所输出的灯光参数依然保持原来状态。无法进行适应性改变，整体智能化水平不高。因此，如何提升照明灯具的智能化水平，是行业内亟需解决的技术问题。
为了使得照明灯具可以针对不同的食物进行调节。故在一些具体实施例中，参考图57和图58，图57是本发明实施例提供的一种自适应照明灯具调节方法的步骤流程图。图58是本发明实施例提供的一种实施环境的示意图。
该实施环境中包括终端设备和服务器，其中，终端设备和服务器之间通过有线或无线通信方式进行直接或间接的连接。其中，终端设备与服务器可以为区块链中的节点，本实施例 对此并不作具体限定。
服务器用于向终端设备提供数据发送、查询和存储功能，也即，终端设备发布的数据可以被服务器进行处理、或者根据数据进行查询和存储。
基于图58所示的实施环境，本发明实施例提供了一种自适应照明灯具调节方法，示例性地应用于图58所示的终端设备中，该自适应照明灯具调节方法包括但不限于以下步骤1至步骤5。
步骤1、获取目标物体的特征信息。
在这个步骤中，终端设备可以通过自身的功能或者利用通讯方式从其他模块中获取得到目标物体的特征信息。所述目标物体的特征信息指的是可以区分并识别目标物体的信息。目标物体指的是需要识别的对象。在本具体实施例中，可以指的是肉类产品或者果蔬产品。在一些进一步可以改进的实施例中，终端设备可以通过控制外部的摄像头来对目标物体进行拍照。从而得到目标物体的图像信息。通过该图像信息则可以将目标物体的特征信息均以图像作为载体进行记录。为了方便描述，将所述图像记为目标图像。当然，目标图像的数量可以是一张，也可以是多张，具体数量的确定则以方便从目标图像中成功提取出目标物体的特征信息为准。
在得到了目标图像后，则可以通过目标图像提取出目标物体的特征信息。在一些实施例中，所述目标物体的特征信息包括目标物体的形状信息和颜色信息。为此，可以将目标图像输入到本地设备，利用本地设备所集成的图像处理算法，来提取目标物体的特征信息。当然，为了降低本地设备的负担，在一些进一步的具体实施例中，也可以通过将目标图像发送非图像处理服务器，由图像处理服务器对目标图像进行处理，从而从目标图像中提取目标物体的特征信息。在得到目标物体的特征信息后，则可以将目标物体的特征信息进行返回给终端设备，从而进入步骤2。
步骤2、将所述特征信息发送给识别服务器。
在这个步骤中，终端设备在得到了目标物体的特征信息后，则可以根据所述特征信息对目标物体进行识别。由于终端设备的识别能力一般有限，故终端设备在得到特征信息后，会将特征信息发送给识别服务器。识别服务器在接收到特征信息后，会通过其集成的识别算法对特征信息进行识别，从而根据特征信息识别出目标物体，得到目标物体的种类。在一些进一步的具体实施例中，识别服务器集成有人工智能算法，通过人工智能算法来对特征信息进行识别，从而得到目标物体的种类。识别服务器在得到了目标物体的种类后，则会将目标物体的种类返回传递给终端设备。
步骤3、接收识别服务器传递回来的目标物体的种类，目标物体的种类记为目标种类。
终端设备在这个步骤中，可以接收到识别服务器传递过来的目标物体的种类。为了方便描述，将目标物体的种类记为目标种类。因此，终端设备就可以接收到目标种类。
步骤4、根据所述目标种类从本地设备或者存储服务器中查询得到对应的输出光谱控制信息。
终端设备在接收到目标种类后，就可以知道当前的目标物体是什么，比如说是肉类产品，还是蔬果产品，亦或者是其他产品。对于不同的产品则已经事先存储有针对该产品的输出光谱控制信息。从而使得照明灯具可以根据输出光谱控制信息来输出对应的光谱，以适应产品的视觉观感。
当然，对于输出光谱控制信息的获取方式，采用是查询的方式。事先在本地设备或者存储服务器中已经存储有目标种类所对应的输出光谱控制信息。因此，只需要针对性进行查询即可获取得到。
步骤5、根据所述输出光谱控制信息控制照明灯具，以使照明灯具调整其的输出光谱。
终端设备在得到了输出光谱控制信息后，就可以控制照明灯具，使得照明灯具可以根据输出光谱控制信息调整其的输出光谱。从而达到照明灯具输出的光谱适应当前的目标物体， 提升当前的目标物体的视觉生鲜感的效果。终端设备可以是灯具的一部分，也可以不是灯具的一部分。
在一些进一步的具体实施例中，终端设备可以与照明灯具通过无线连接的方式进行通讯互动。终端设备准备控制照明灯具的时候，其会通过本地设备查询的预先存储的照明灯具的访问地址。这里的访问地址可以为物联网地址，也可以为其他的自定义地址。通过访问地址，终端设备就可以与照明灯具建立通讯链接，从而得到链接通道。在得到了链接通道后，终端设备就可以根据链接通道与照明灯具建立可靠的通讯。通过链接通道向照明灯具发送光谱控制信息。照明灯具在接收到光谱控制信息后，就可以从光谱控制信息中得到了需要输出的输出光谱的信息。照明灯具通过自身调整，可以将其的输出光的光谱调整为输出光谱，以适应目标物体。
本发明通过对目标物体的智能识别，并根据识别结果调整照射到目标物体的照明灯具的输出光谱，从而使得输出光谱更加适合目标物体。从而解决了现有技术中以为目标物体的改变，而导致无法及时改变照明灯具的输出光谱的情况。
在一些进一步的具体实施例中，当确定目标物种的种类为肉类时，根据所述输出光谱控制信息控制照明灯具，以使照明灯具调整其的输出光谱，其中，照明灯具调整其的输出光谱包括：发出白光，所述白光的光谱曲线具有第一光谱特征、第二光谱特征和第三光谱特征；所述第一光谱特征包括在380nm-476nm的波长范围内的第一波峰；所述第二光谱特征包括在476nm-589nm的波长范围内的第二波峰；所述第三光谱特征包括在589nm-780nm的波长范围内的第三波峰；所述第一波峰的峰值处的光谱强度为第三波峰的峰值处的光谱强度的23％-40％；所述第二波峰的峰值处的光谱强度为第三波峰的峰值处的光谱强度的27％-38％。

本领域普通技术人员可以理解，上文中所公开方法中的全部或某些步骤、系统可以被实施为软件、固件、硬件及其适当的组合。某些物理组件或所有物理组件可以被实施为由处理器，如中央处理器、数字信号处理器或微处理器执行的软件，或者被实施为硬件，或者被实施为集成电路，如专用集成电路。这样的软件可以分布在计算机可读介质上，计算机可读介质可以包括计算机存储介质(或非暂时性介质)和通信介质(或暂时性介质)。如本领域普通技术人员公知的，术语计算机存储介质包括在用于存储信息(诸如计算机可读指令、数据结构、程序模块或其他数据)的任何方法或技术中实施的易失性和非易失性、可移除和不可移除介质。计算机存储介质包括但不限于RAM、ROM、EEPROM、闪存或其他存储器技术、CD-ROM、数字多功能盘(DVD)或其他光盘存储、磁盒、磁带、磁盘存储或其他磁存储设备、或者可以用于存储期望的信息并且可以被计算机访问的任何其他的介质。此外，本领域普通技术人员公知的是，通信介质通常包含计算机可读指令、数据结构、程序模块或者诸如载波或其他传输机制之类的调制数据信号中的其他数据，并且可包括任何信息递送介质。
参考图60，第三方面，提供一种自适应照明灯具调节系统，包括：获取单元、发送单元、接收单元、查询单元和控制单元。
其中，当本自适应照明灯具调节系统工作时，获取单元的作用是获取目标物体的特征信息。获取单元在获取了特征信息后，则会将特征信息传递给发送单元。所述发送单元在接收到特征信息后，则会将特征信息进行转发，从而将特征信息传递给识别服务器。
识别服务器在接收到特征信息后，会通过其集成的识别算法对特征信息进行识别，从而根据特征信息识别出目标物体，得到目标物体的种类。在一些进一步的具体实施例中，识别服务器集成有人工智能算法，通过人工智能算法来对特征信息进行识别，从而得到目标物体的种类。识别服务器在得到了目标物体的种类后，则会将目标物体的种类返回传递给接收单元。
所述接收单元可以从识别服务器中接收得到目标物体的种类，为了便于描述，所述目标物体的种类记为目标种类。接收单元在得到了目标种类后，则会将目标种类传递给查询单元。
查询单元在接收到目标种类后，就可以知道当前的目标物体是什么，比如说是肉类产品，还是蔬果产品，亦或者是其他产品。对于不同的产品则已经事先存储有针对该产品的输出光谱控制信息。从而使得照明灯具可以根据输出光谱控制信息来输出对应的光谱，以适应产品的视觉观感。
当然，对于输出光谱控制信息的获取方式，查询单元采用是查询的方式来得到。事先在本地设备或者存储服务器中已经存储有目标种类所对应的输出光谱控制信息。因此，查询单元只需要针对性进行查询即可获取得到。
查询单元在得到了输出光谱控制信息后，就会将输出光谱控制信息传递给控制单元。控制单元的作用是通过与照明灯具建立联系，根据所述输出光谱控制信息控制照明灯具，从而 使得照明灯具可以根据输出光谱控制信息调整其的输出光谱。实现了对照明灯具控制的目标。
本发明的系统通过对目标物体的智能识别，并根据识别结果调整照射到目标物体的照明灯具的输出光谱，从而使得输出光谱更加适合目标物体。从而解决了现有技术中以为目标物体的改变，而导致无法及时改变照明灯具的输出光谱的情况。
对于获取单元、发送单元、接收单元、查询单元和控制单元，在一些进一步的具体实施例中。四个单元均可以集成在同一个设备中。
在一些进一步的具体实施例中，控制单元由四个调节单元组成，分别为第一调节单元、第二调节单元、第三调节单元和第四调节单元。第一调节单元、第二调节单元、第三调节单元和第四调节单元，通过四个调节单元对照明灯具进行控制，从而调整照明灯具的光谱和色温，从而达到对应的光学效果。其中，照明灯具具有四个单色光通道，在本具体实施例中，四个单色光通道分别为：红色通道、绿色通道、蓝色通道和白色通道。当然，这四个单色光通道还可以通过其他的单色光组合，这里就不展开描述了。本具体实施例则以红色通道、绿色通道、蓝色通道和白色通道为例子。其中，第一调节单元用于调节红色通道的亮度，第二调节单元用于调节绿色通道的亮度，第三调节单元用于调节蓝色通道的亮度，第四调节单元用于调节白色通道的亮度。其中，第一调节单元、第二调节单元、第三调节单元和第四调节单元采用PWM调节方式进行调节。在PWM调节技术中，将控制单元的PWM调节分成256个等级，其中，第一调节单元为0-50级，第二调节单元为50-100级，第三调节单元为100-150级，第四调节单元为100-255级。通过四个单色光通道的调节，从而使得照明灯具输出对应的光谱。
第三方面，本发明还提供了一种计算机可读存储介质，其中存储有处理器可执行的程序，所述处理器可执行的程序被处理器执行时用于实现如前面任意实施例所述的自适应照明灯具调节方法。
本申请实施例还公开了一种计算机程序产品，包括计算机程序或计算机指令，计算机程序或计算机指令存储在计算机可读存储介质中，计算机设备的处理器从计算机可读存储介质读取计算机程序或计算机指令，处理器执行计算机程序或计算机指令，使得计算机设备执行如前面任意实施例所述的自适应照明灯具调节方法。
对于上述方法实施例中的步骤编号，其仅为了便于阐述说明而设置，对步骤之间的顺序不做任何限定，实施例中的各步骤的执行顺序均可根据本领域技术人员的理解来进行适应性调整。
在对于一个光源的光谱特定的时候，需要进行多次对光源进行调整，从而得到最佳的光源的光谱。但是，现有的调整方式一般通过调整色温或者色彩饱和度等。但是，对于生鲜产品来讲，并没有存在一个很系统的调试方法，因此，对于生鲜产品的照明来讲，往往需要较为复杂的调试方式。
以上对本发明的较佳实施方式进行了具体说明，但本发明创造并不限于所述实施例，熟悉本领域的技术人员在不违背本发明精神的前提下还可做出种种的等同变型或替换，这些等同的变型或替换均包含在本申请权利要求所限定的范围内。
