A recently granted patent (Publication Number: US11919442B2) discloses a vehicle interior lighting device designed to enhance the aesthetics of a vehicle's interior. The device includes a light source installed on the instrument panel of a vehicle, projecting light onto the door trim of a door panel through a pattern element. The light source is strategically positioned to create a pattern on the door trim surface, with the pattern changing in response to the opening and closing of the door to which the panel is installed.

Furthermore, the patented vehicle interior lighting device incorporates intelligent features such as automatic shut-off after a predetermined time period following the opening of the door. Additionally, the device is capable of projecting light in different colors based on the door's status - illuminating in a first color when the door is opened and switching to a second color when the door is closed. These innovative functionalities not only add a touch of sophistication to the vehicle's interior but also contribute to enhancing the overall user experience by providing dynamic and customizable lighting effects based on door movements.
