Abstract
The invention provides artificial skylights rendering a realistic view to the sky, by providing natural feeling patterns, dynamics and tonalities of vertical illumination, and shadow patterns. Thereto a light generating system is provided to generate dynamic and recognizable content, and in particular dapple, by providing a light generation device combining a first layer of randomly (uncontrolled) operating, low intensity LEDS with a (nested) second layer of controlled higher intensity LEDs, thereby substantially reducing device and control costs. The ratio of randomly operating LEDs/controlled LEDs is about 3:1.
