1. A method of generating an image of a sky portion comprising the steps of:
providing an LED fixture for creating an illusion of a sky portion;
providing an LED driver signal system configured to provide improved realism by persons viewing the LED fixture for extended periods of time, by utilizing multiple modulation methods which are not limited to circadian rhythms alone;
wherein said step of utilizing multiple modulation methods further comprises utilizing an ultradian modulation method;
wherein, the ultradian modulation method comprises: using a light sensor to measure outdoor light intensity levels over a plurality of different periods of time, and generating datasets therefrom, where the variations in data reflects the presence of clouds passing between the light sensor and the sun;
using the datasets to generate grayscale videos where 100% brightness is white, and 0% brightness is black;
uploading the grayscale videos to a lighting controller;
randomly calling the grayscale videos throughout a day to provide an ultradian modulation method to LED driver signals;
wherein said lighting controller is the LPC 550;
wherein said fixture and said LED drive signal system provide output of light based upon registration of drive signals with predetermined locations of cloud images on an image panel;
wherein the ultradian modulation method is used for generating a driver signal to create an illusion of a non-static image of a cloud with a static image panel;
where the range of brightness is limited to being between 100% and 40%; and
wherein said LED fixture comprises a plurality of parallel white LED strips, where a plurality of RGB LED modules are disposed between said plurality of parallel white LED strips; and each of the RGB LED modules is configured to provide light in six wavelengths-Lime Green, Mint Green, Amber, Red-Orange, Red, and Cool White so as to generates a high CRI (Color Rendering Index) that improves realism of the image on the image panel.
