Distributed light source method for displaying moving images
The patent US12033547B2 outlines a method for operating a distributed light source composed of multiple individually controllable light sources arranged in a grid to display moving images. The process begins with a central controller transmitting an entire image to each light source, which includes illumination data formatted within an image coordinate system represented as a matrix. Each light source receives specific coordinates that dictate the desired illumination characteristics, such as intensity and color, for its designated location in the image. The light sources store portions of the received image and utilize position information to determine their respective illumination set points. This allows the light sources to generate the necessary illumination to display the image accurately. Following the display of an image, the system efficiently updates the illumination for the next image by providing only the position information for light sources that experience a change in coordinates, thereby optimizing data bandwidth.
Additionally, the patent describes the configuration of the distributed light source, which includes a central controller and a grid of light sources equipped with LED assemblies, power converters, and light source controllers. These controllers are responsible for receiving image signals, determining illumination set points based on position information, and controlling the light sources to produce the required illumination. The method allows for the display of high-resolution images while managing bandwidth effectively by transmitting only the necessary data for light sources that change position. This innovative approach enhances the efficiency of displaying moving images in a distributed lighting system, making it suitable for various applications where dynamic visual displays are required.
