图2所示为本申请的激光投线仪根据环境温度变化和/或电池电量变化调整激光二极管的工作功率级别的原理流程图。根据图2，当所述激光投线仪开机之后，所述激光投线仪默认以默认的工作功率级别工作。随后，激光投线仪的温度传感器检测环境温度是否达到对应的温度阈值区间，以及检测电池的剩余电量是否达到对应的电量阈值区间。如果环境温度达到对应的温度阈值区间(高温阈值区间或低温阈值区间)，或者，检测电池的剩余电量达到对应的电量阈值区间时，则主控单元将将激光二极管的工作功率调控至相应的工作功率级别；如果两者都不满足，则以默认工作功率工作；如果环境温度均没有达到对应的温度阈值区间(高温阈值区间和低温阈值区间)，并且，检测电池的剩余电量达到对应的电量阈值区间时，则主控单元将将激光二极管的工作功率调控至相应的工作功率级别；如果环境温度均没有达到对应的温度阈值区间(高温阈值区间和低温阈值区间)，并且，检测电池的剩余电量也没有达到对应的电量阈值区间时，则所述激光二极管以默认工作功率工作。
本领域技术人员可知，示例地，如图3所示，本申请的激光投线仪还可以设置为优先检测环境温度是否达到对应的温度阈值区间(高温阈值区间和低温阈值区间)，如果环境温度达到高温阈值区间或低温阈值区间，则主控单元将将激光二极管的工作功率调控至相应的工作功率级别，不再检测电池的剩余电量是否达到对应的电量阈值区间；如果环境温度没有达到高温阈值区间和低温阈值区间，换句话说，当环境温度处于默认温度阈值区间内时，则进一步检测电池的剩余电量是否达到对应的电量阈值区间，如果达到对应的电量阈值区间，则主控单元将将激光二极管的工作功率调控至相应的工作功率级别，如果也没有达到对应的电量阈值区间，则所述激光二极管以默认工作功率工作。
以上对本发明的具体实施例进行了详细描述，但其只是作为范例，本发明并不限制于以上描述的具体实施例。对于本领域技术人员而言，任何对本发明进行的等同修改和替代也都在本发明的范畴之中。因此，在不脱离本发明的精神和范围下所作的均等变换和修改，都应涵盖在本发明的范围内。
