artificial LED skylights designed to simulate natural sunlight and the appearance of a blue sky indoors. They provide soft, uniform light, reducing glare and shadows in spaces without natural windows. The technology uses advanced optics and LED panels to create a perception of depth and boundless space. These systems can simulate the pure sky light and even dynamic changes like sunrise and sunset to support natural circadian rhythms. They are commonly used in offices, basements, and other interior spaces to improve mental health and well-being where natural light is limited. .
