  • Patent number: 9113508
    Abstract: Disclosed are methods and systems for controlling of a lighting system with a plurality of light sources, particularly to the semi-automatic commissioning of light sources of the lighting system or controlling of the creation of lighting scenes with the lighting system. A spatial coding of light is used for controlling a lighting system, particularly for commissioning of light sources of the lighting system. Some exemplary systems for controlling a lighting system with a plurality of light sources, include a light system controller for controlling the light sources to create a spatial light pattern coding one or more attributes of the light sources, and a light pattern capturing device comprising a scanner for capturing the created spatial light pattern and a communication unit for communicating with the light system controller in order to enable the controlling of the one or more light sources based on the captured spatial light pattern.

  • Patent number: 8552666
    Abstract: The invention relates to the controlling of a lighting system with a plurality of light sources, particularly to the semi-automatic commissioning of light sources of the lighting system or controlling of the creation of lighting scenes with the lighting system. A basic idea of the invention is to use a spatial coding of light for controlling a lighting system, particularly for commissioning of light sources of the lighting system instead of or in addition to the temporal light coding as applied in the prior art.

  • Patent number: 5650694
    Abstract: A ballast includes safety circuitry which senses lamp status through various phases of ballast operation. According to one feature, the ballast is prevented from supplying an output voltage upon initial energization of the ballast when a lamp is not present at the output terminals. The presence of a filament is sensed via a DC path extending through the filament heater windings of an output transformer. When the DC path is not complete, a control input, for example the power supply input of the ballast controller, is not provided with a voltage to start ballast operation. The DC path is also used to restart the ballast if a defective lamp is replaced with a good one. Over-voltage and capacitive mode detection is also disclosed to shut down ballast output upon lamp failure/removal.

  • Patent number: 5369340
    Abstract: A driving scheme for a high intensity discharge lamp. The driving scheme eliminates the need for a level shifter by requiring only one reference level in determining the level of current to be produced by the down converter. The down converter has a substantially constant D.C. voltage input and consumes a relatively low amount of fixed power relative to the load attached across the output of the down converter.

  • Patent number: 5319286
    Abstract: An ignition scheme for a high intensity discharge ballast. The ballast includes a down converter for producing a varying level of current during the glow stage of the lamp. The level of current available at the time of lamp ignition is equal to or greater than any other level of current produced during at least takeover of the lamp. The need for building up the level of current during at least takeover is eliminated thereby minimizing the need for re-ignition of the lamp.
