Abstract:
1. An outdoor light system comprising: a plurality of devices linked to a central controller disposed remotely from each of the plurality of devices, each device comprising a white light source, at least one light group comprising red, green and blue lights, and a replaceable insert containing a volatile active material, and a transducer for transmitting sound, and the central controller comprising a memory for storing at least one light and sound show, the controller being programmed to simultaneously operate the plurality of devices to carry out the at least one light and sound show through the plurality of devices, each light show comprising starting and target points corresponding to starting and target intensity levels for each of the LEDs off each of said devices with a segment extending continuously between the starting and target points and timing information for a duration of the segment for each of said devices, the central controller being programmed to calculate a plurality of intermediate intensity levels for each of the LEDs for the duration of the segments for each of said devices based on the starting and target intensity levels and the timing information for each of the LEDs, and the central corns oiler controlling each of the LEDs to operate at each of the calculated intermediate intensity levels during the segments to present a continuous change in color during each segment, each starting and target points and each segment extending therebetween falling within an area of a CIE 1931 Color Diagram defined by the following sets of coordinates (0.70, 0.30), (0.19, 0.72), (0.14, 0.06).
