具体实施方式
如背景技术所述，目前的光消毒装置多为固定结构，照射出的消毒光线具有指向性，存在照射死角，输出范围有限，存在光线强弱之分，无法实现室内全方位消毒杀菌，并且紫外线长时间在局部照射，容易造成局部剂量过高导致的热点问题，局部紫外线强度过高且照射时间过长，导致照射剂量超过国际安全剂量标准，不利于生物健康。并且，光消毒装置无法根据具体的使用场景和想要达成的消毒效果灵活设置，不利于提高消毒效率。
为了解决上述问题，本发明实施例提供了一种消毒灯的动态均光方法，一方面，所述消毒灯可以在空间内运动，因此所述消毒灯可以多消毒对室内空气以及物表进行消毒，避免消毒光线存在照射死角的问题，实现室内全方位消毒杀菌；同时避免紫外线光在局部区域停留时间过长，避免局部剂量过高造成的光生物危害以及物品的损伤，以及局部区域长时间增加照射剂量造成的能量浪费；另一方面，根据目标消毒剂量和安全消毒剂量调整消毒灯的初始配光数据或者消毒灯 的运动参数，从而根据应用场景配置出最佳的消毒灯装配方案，有利于提高消毒效果且能达到生物安全要求。

步骤S5：根据所述剂量等效配光数据调整所述消毒灯的参数或者所述消毒灯的运动参数。
参考图5，在步骤S5中，根据剂量等效配光数据调整所述消毒灯10的初始配光数据或者消毒灯10的运动参数的方法包括：
步骤5.1：根据所述剂量等效配光数据，获得所述消毒灯在运动时的剂量等效消毒剂量；

所述剂量等效消毒剂量为空间内各个被辐射点的消毒剂量，包括最大消毒剂量和最小消毒剂量。

目标消毒剂量设置为消灭空间内细菌或者微生物需要的消毒剂量，所述目标消毒剂量可以根据具体使用场景设置，每个场景中主要存在的细菌或者微生物种类不同，不同的微生物种类杀灭需要的消毒 剂量不同，因此可以根据使用场景进行调整；另外，还可以根据消毒效果进行调整，例如要求消毒效果达到99％或者要求达到95％，均对应不同的消毒剂量。
因此，所述目标消毒剂量的影响因素包括目标微生物的种类、目标微生物的消杀完成度以及目标微生物的载体。
所述目标消毒剂量可以根据具体情况具体设定。
所述安全消毒剂量设置为空间内人类等生物能承受的消毒剂量，一旦剂量等效消毒剂量超过人类等生物能承受的安全消毒剂量，会对人体健康造成危害。

本实施例中，所述有效辐射剂量曝辐限制的数值同样参考GBT20145-2006，国标修改后，有效辐射剂量曝辐限制的数值参考修改后的国标。
本实施例中，如果剂量等效消毒剂量大于等于目标消毒剂量，且小于等于安全消毒剂量，则表示消毒灯10在当前使用环境中可以达成目标消毒效果，且不会对生物造成危害，因此不需要对调整消毒灯10本身或者其运动参数；如果剂量等效消毒剂量小于目标消毒剂量，或者大于安全消毒剂量范围，则需要调整消毒灯10的初始配光数据或者消毒灯10的运动参数。
本实施例中，如果剂量等效消毒剂量小于目标消毒剂量，或者大于安全消毒剂量范围，也可以调整消毒灯10的数量等参数。
如果剂量等效消毒剂量小于目标消毒剂量，说明消毒效果不达标，调整消毒灯10的初始配光数据包括提高消毒灯10的初始辐射强度，即更换消毒灯，采用初始辐射强度较高的消毒灯；或者可以增加消毒灯10的数量。
调整消毒灯10的运动参数包括：如果消毒灯10在做旋转运动，可以增加旋转角度，以避免空间内部分角度无法照射到消毒光线；如果消毒灯10在做位移运动，可以增加位移轨道的长度，或者改变位移轨道的安装形式，例如从直线型改成U型等。
如果剂量等效消毒剂量大于安全消毒剂量范围，说明消毒剂量会对生物造成伤害，调整消毒灯10的初始配光数据包括降低消毒灯10的初始辐射强度，即更换消毒灯，采用初始辐射强度较低的消毒灯；或者减少消毒灯10的数量。
调整消毒灯10的运动参数包括：如果消毒灯10在做旋转运动，可以提高转动速度，避免消毒灯10在某个角度停留时间过长，导致局部剂量过高；如果消毒灯10在做位移运动，可以提高移动速度，避免消毒灯10在某个位置停留时间过长，导致局部剂量过高。
虽然本发明披露如上，但本发明并非限定于此。任何本领域技术人员，在不脱离本发明的精神和范围内，均可作各种更动与修改，因此本发明的保护范围应当以权利要求所限定的范围为准。
