Method and system for regulating the light intensity in a room illuminated by daylight and artificial light

摘要

A source (2) of light illuminates a room. An internal sensor (4) detects brightness in the room. A control device (1) relies on the test signal from the internal sensor to trigger the source of light. An external sensor (5) detects external light (La). An independent claim is also included for a method for controlling brightness in a room lit by internal and external light.
