  • 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.
    Type: Grant

  • Patent number: 8350667
    Abstract: A method for the start-up of a lighting system having lamps and a central control system, wherein each lamp has an identification code independently of its position and a position code assigned by a control device, has the following steps: a) Separating the lamps into two groups by putting one group in a first state and the other group in a second state, b) selecting one of the lamps and entering its state into the operating device selecting the group of lamps that has the same state as the selected lamp for further steps, while the other group is no longer considered, d) when the selected group does not only have the selected lamp, the steps a)-d) are carried out again e) assigning the position code to the remaining lamp, to bring the code directly into relation with the identification code, f) carrying out the steps a)-e) for further lamps.
