  • Patent number: 10660187
    Abstract: A lighting system and its method of operation that enables multiple independent light assemblies to be simultaneously controlled. The light assemblies contain a matrix of LEDs that are capable of generating different color profiles throughout a range of intensities. The light assemblies also contain a control module that controls the color profiles and the range of intensities being produced by the LEDs. A custom software application is run on a smartphone. The software application enables manual selection of the color profiles and the range of intensities, and the smartphone generates command signals that are transmitted to the light assemblies for execution. The software application generates a control screen on the smartphone that plots the color profiles against the range of intensities. The color profiles and the range of intensities are selected by touching a point on the control screen.
