摘要： The invention relates to a lighting system (10), a method of controlling the lighting system and a computer program product. The lighting system comprises a light source (30), a controller (100) for controlling the light source (30), and a light sensor (20). The light source is configured for altering a spectrum of the light emitted by the light source. The light sensor is arranged for sensing spectral information comprising at least two different portions of a spectrum of light impinging on the light sensor. The controller is configured for receiving a sense signal (SS) and for generating a drive signal (DS) supplied to the light source to determine the spectrum of the light emitted by the light source in dependence on the spectral information from the light sensor. The effect of the measures according to the invention is that the sensing of the spectral information of the light impinging on the light sensor enables the controller to adapt the color temperature of the light emitted by the light source such that the perceived color temperature more closely corresponds to the intended color temperature.

摘要： The present invention is related to an electrical energy conversion circuit device (190), a method (600) of operating an electrical energy conversion circuit device, an electrical apparatus (500) and a computer program. The circuit device (190) allows earth connection and comprises two parallel connected buck-boost converters for converting a direct input voltage (110) into a direct output voltage (120). The converters are adapted to generate two phase-shifted currents (131, 141) that are received by an output capacitor (160). Due to the phase-shift, a current ripple is reduced. The direct output voltage (120) and the direct input voltage (110) preferentially have a common potential (114) and are of opposite polarities. Therefore, a second voltage of high magnitude, the sum of the direct input voltage (110) and the direct output voltage (120) is also provided.

摘要： A method and inverter (2, 27) for converting a DC input voltage supplied by a DC source (9), which is in particular a solar cell array, into a 3 -phase AC output. For each phase (R, S, T) the DC input voltage is converted to a DC output voltage (DCR, DCS, DCT) with a specific waveform. The waveforms of the three DC output voltages are identical, shifted in time by 120° to each other and they are such that by subtracting any two of them a sinusoidal waveform is obtained. The waveform of each DC output voltage may comprise a first portion of 1/3 or 120° of the AC output cycle with an amplitude of zero and a subsequent second portion of 2/3 or 240° of the AC output cycle during which the DC output voltage has a non-zero amplitude.

摘要： Supply circuits for supplying voltage and current signals to light sources (6) comprise switches (22, 32, 42, 52) and controllers (21, 31, 41, 51) to control the switches (22, 32, 42, 52) for reducing values of frequency components of harmonic content of power spectra of the light sources (6). By switching one of the voltage and current signals or by switching signals that result in one of the voltage and current signals, the other one of the voltage and current signals can be adjusted. The power spectrum of the light source (6) may be a function of the voltage and current signals. By adjusting one of them, the power spectrum can be adjusted such that values of frequency components of the harmonic content of the power spectrum are reduced. As a result, visible flicker is reduced in the light originating from the light source (6) without the use of energy storage capacitors for reducing this visible flicker.
