Abstract: The light-radiating semiconductor component has a radiation-emitting semiconductor body and a luminescence conversion element. The semiconductor body emits radiation in the ultraviolet, blue and/or green spectral region and the luminescence conversion element converts a portion of the radiation into radiation of a longer wavelength. This makes it possible to produce light-emitting diodes which radiate polychromatic light, in particular white light, with only a single light-emitting semiconductor body. A particularly preferred luminescence conversion dye is YAG:Ce.

Abstract: An impedance measurement circuit comprises a current source arrangement, a voltage measurement arrangement and a processor. The circuit is operable in a two-point measurement mode and a four-point measurement mode and the processor is adapted to derive the impedance to be measured by combining the measurement voltages from the two-point and the four-point measurement modes. This combines the results of both two-point and four-point measurement techniques to provide improved accuracy. In particular, the two results enable the effect of the electrode resistance to be cancelled.

Abstract: A method and a particle sensor (5) are provided for measuring particles, especially soot particles. The particles to be detected accumulate in a measuring region (10) of the particle sensor (5).

The physical variable of the combustion device (15), which leads to the controlled combustion of the particles, is drawn upon as the signal amplitude of the particle sensor (5).
