  • Synchronization of dimmer controls
    Patent number: 10856390
    Abstract: Various embodiments include a lighting system comprising: a first light; a second light; a first controller for adjusting a first brightness of the first light; a second controller for adjusting a second brightness of the second light; and a generator for generating a trigger signal. The first controller and the second controller are initiated by the trigger signal, to simultaneously start a control computation procedure.
    Type: Grant

  • Method for open-loop and closed-loop control of a lighting busway
    Patent number: 9179524
    Abstract: A method for open-loop and closed-loop control of a lighting busway with a primary luminaire and at least one secondary luminaire for an interior space, involves measuring a brightness at the location of the primary luminaire, determining a primary ambient light percentage for the primary luminaire, determining a secondary ambient light percentage for at least one secondary luminaire based on the primary ambient light percentage, and determining a secondary manipulated variable for at least one secondary luminaire based on the secondary ambient light percentage and a setpoint value for this secondary luminaire.
