    摘要: The invention relates to embedding data symbols of a data signal into a luminance output of an illumination device. The device includes a controller configured for receiving a first base pattern and a second base pattern within a frame period, and generating a shifted second pattern by phase shifting the second base pattern within the frame period with respect to the first base pattern in response to the data signal such that the data symbols are embedded in the luminance output of the device. The device also includes a first light source configured to generate a first luminance output in response to the first base pattern and a second light source configured to generate a second luminance output in response to the shifted second pattern. The first and second luminance outputs have different output spectra and the luminance output of the illumination device comprises both the first and second luminance outputs. With this approach, the short-time average light output of the illumination device remains constant, decreasing the visible flicker and allowing the use of lower switching frequencies relative to the prior art approaches.

    摘要: 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. An embodiment of the invention relates to a system for controlling a lighting system with a plurality of light sources (1, 2) comprising a light system controller (5) for controlling the light sources in that a spatial light pattern (11, 12, 21, 22) is created, which codes one or more attributes (512) of the light sources (511), and a light pattern capturing device (3) for capturing the created spatial light pattern and communicating (32, 52) with the light system controller (5) in order to enable the controlling of the one or more light sources based on the captured spatial light pattern. A spatial coding is particularly suitable for wallwasher light sources, and thus especially assists personnel in commissioning wallwasher light sources of a lighting system.

    摘要: A piezoelectric driving device and a regulation method for a piezoelectric driving device are proposed. Piezoelectric driving devices known so far show a characteristic with which the electric power applied to the motor drops when the load increases. This behavior, which leads to a strong reduction of the range of use of such motors, is counteracted by predefining the amplitude of the excitation voltage so that the effective power does not drop with increasing load. For this purpose the electrical effective power is determined from the excitation voltage and the current flowing through the piezoelectric resonator. Alternatively, with a predefined fixed phase angle between excitation voltage and current a regulation may also be effected in the way that the current is kept to the constant value. A further aspect of the invention relates to a unit for limiting the current flowing through the piezoelectric resonator, so as to avoid this component being damaged.

    摘要: A circuit arrangement for commutating the AC voltage of a plasma display panel, in which the losses and electro-magnetic interference which occur as a result of the influence of parasitic resistances (coils, supply lines, semiconductor switches) and the attendant hard charging and discharging processes, are substantially avoided. For the charging operation of the capacitor (Cp) of the plasma cells the oscillation circuit is supplied with an auxiliary charging voltage (u1) whose value exceeds 50% of the input voltage (U0). The oscillation circuit for the discharging operation is supplied with an auxiliary discharging voltage (u2) whose value falls short of 50% of the input voltage (U0). The two auxiliary voltages are connected to a DC converter.
