HarveStar Shades
designed to comply with Daylight Harvesting Principle: Catch the daylight as much as possible across the day to illuminate interiors, but keeping light level constant; also complement the system with low-consumption LED light when exterior lights are not enough.
HarveStar Shades solution mimics the nature: The engineering of the eye! It control the light that comes in to the interiors with a diaphragm iris, automatically regulated by a electronic controller with light sensors, that reduce the open when the sun shines, and increase the open when the daylight brings down.
