摘要： The present invention relates to a lighting device for illuminating a target object with the objective to draw a person's attention to this target object. It alternatingly provides a relatively fast dynamic light output component and a relatively slow dynamic light output component, the former being predominantly for triggering a person's attention towards a target object, while the latter is mainly for enhancing the visual appearance of the target object, thereby keeping someone's attention for that object. For this purpose, the lighting device is arranged to provide a primary light output alternatingly comprising a first light output component and a second light output component. The lighting device comprises a switching controller for switching between the first light output component and the second light output component after a time interval. The primary light output has a perceived light intensity that remains constant over time within a margin of 10%. Each of the first and second light output components is characterized by a light output characteristic. The light output characteristic for the first light output component varies over time according to a first waveform, and the light output characteristic for the second light output component varies over time according to a second waveform. Each of the first and second waveforms is characterized by a time constant. The time constant has a first value for the first waveform and a second value for the second waveform, the first value being lower than the second value. The time interval for switching between the first and second light output components is between 0.1 seconds and 30 seconds.

摘要： The invention relates to an arrangement (100) comprising a lighting system (110) and a target object (120), wherein the lighting system (110) is arranged to illuminate a target surface of the target object (120) with a primary light output (111) and with a secondary light output (112). Each of these light outputs has an illumination spectrum representing a color. The two illumination spectra are different, but the two colors are substantially the same. The target surface has a first target surface area and a second target surface area. When the first and second target surface areas are illuminated with the primary light output (111), they have a contrast that is lower than when they are illuminated with the secondary light output (112). The arrangement of the invention can be used for atmosphere creation or for attracting attention to the target object (120).

摘要： In a method of lighting at least part of a space, a light emitting diode (LED) string is used. The LED string comprises a first LED segment and at least one further LED segment, which are connected in series, each LED segment comprising at least one LED. The LED string is powered by a rectified AC voltage. The first LED segment is powered when the rectified AC voltage is above a first voltage level, and the first LED segment and the further LED segment are powered when the rectified AC voltage is above a second voltage level higher than the first voltage level. The first LED segment is arranged to radiate light to a first volume of the space, and the further LED segment is arranged to radiate light to a second volume of the space, the first volume being at least partly different from the second volume. The first volume may at least partly overlap the second volume.

摘要： Drivers (1-7) comprise respective switching circuits (1, 2) for guiding respective current signals during respective time-intervals for the sequential driving of light emitting circuits (91, 92). The respective time-intervals are defined by the fact that amplitudes of a mains signal are in respective ranges during the respective time-intervals. More specifically, there is a bypass switching circuit (5) for guiding a bypass current signal which bypasses all light emitting circuit (91, 92) during an initial time-interval. An adaptation circuit (6, 7) adapts amplitudes of the respective current signals during the respective time-intervals, to reduce a total harmonic distortion. Said adapting may comprise an adaptation in response to information derived from the amplitude of the mains signal, and may comprise shaping the amplitudes of the current signals in response to information derived from the amplitude of the mains signal. Preferably, the shaped amplitudes of the respective current signals will be substantially identical to shapes of the amplitude of the mains signal in the respective ranges. The adaptation circuit (6, 7) may comprise a current source (6) and a definition circuit (7).

摘要： Drivers (2) comprise converters (21) for converting input signals from dimmers (1) into output signals destined for light emitting diode circuits (3) and controllers (22) for detecting dimming levels of the input signals and for bringing the drivers (2) from first, normal dimming modes into second, eco dimming modes in response to detection results defining the dimming levels being equal to/smaller than threshold levels. In the first/second dimming modes, the first input signals are converted into first/second output signals according to first/second curves (I, II). The second curves (II) define higher light outputs than the first curves (I) for most of the dimming levels. Dimmers (1) comprise indicators (11, 2, 13) for indicating to users the dimming levels of the input signals being equal to/smaller than the threshold levels. The indicators (11, 12, 13) may comprise light emitting diode 10 apparatuses (11), mechanical clicks when turning knobs (12) and markers or markings (13) on the dimmer.
