  • Patent number: 12128159
    Abstract: An illumination lamp system having automatic switching function for sterilization is disclosed. It contains a plurality of germicidal lighting lamp assemblies, a personnel counter, a data receiving indicator, and an ultraviolet indicator. Each germicidal lighting lamp assembly includes a lamp panel, an infrared human body sensor and a control module. The control module includes a power conversion unit, a synchronization interface, a startup circuit, a first microcontroller, and an output and input connection interface. Because the infrared human body sensor can detect the appearance of people in real time, with a synchronous voltage to switch emitting between illumination LED strips and ultraviolet germicidal light sources, in addition to effectively expanding the disinfection area, it can also safely adjust the type of light to achieve the automatic switching function for sterilization.
