[0002] An existing patent (Announcement No.: CN216849231U) discloses an infrared sensing control device for an advertising light box. This utility model solves the problem that existing advertising light boxes are difficult to install infrared sensing controllers and easily cause the outer shell of the infrared sensing control device to slip and be damaged by providing a fixing slot and a limiting mechanism. However, in actual applications, since infrared sensing control devices come in different models and there are differences in function and structure between different models, the sizes of different infrared sensing control devices vary. The above utility model cannot adjust the spacing between adjacent positioning blocks, resulting in that the utility model can only be used for the installation of infrared sensing control devices of fixed sizes, which is limited in use and not conducive to widespread use. To this end, we propose an infrared sensing control device for an advertising light box. Utility Model Content
