The door light is an auxiliary indication device of the ward call system, typically installed on the outside of the patient room door or above the door frame within the nurse‘s line of sight. It receives call signals from the master station or bedside unit and uses different colored lights (e.g., red for emergency call, green/yellow for normal call or assistance request) to visually indicate the room’s call status, allowing nurses to quickly locate requesting rooms during corridor rounds. Featuring high-brightness LED light sources with low power consumption and long service life, the door light supports steady-on or flashing modes. It is an essential auxiliary device for improving nursing response efficiency and ward management visualization.
