This utility model provides a light-driven smart window, relating to the field of window structure technology, to address the shortcomings of existing windows in terms of environmental perception and adaptive adjustment capabilities. When encountering sudden heavy rain or other severe weather, these windows fail to automatically trigger closing, leading to water backflow, damage to indoor items, and even safety hazards such as wall seepage and short circuits when the user is not manually closing the window or when the window is unattended. This seriously affects building safety and the living experience. The solution involves a sensor module located at the lower front end of the frame. When rain falls, rainwater enters the sensor module through a drain hole, triggering its operation. The sensor module then sends a command to the motor driving the lead screw, automatically closing the window. This design enables the window to automatically respond to severe weather, preventing rainwater backflow due to user negligence or when the window is unattended, effectively protecting the indoor environment and items, and significantly improving building safety and the living experience.
