    Abstract: Controlling a lighting system, which comprises a controller (2, 10), lighting units (6), and a sensing device. Each lighting unit comprises a lighting source (12) and a modulated light source (14). A single light source may be used to function as both the lighting source and the modulated light source. Each modulated light source emits uniquely modulated light. A radiation pattern of each modulated light source coincides substantially with a radiation pattern of a lighting source of the same lighting unit. The sensing device is suitable to sense modulated light in a viewing area. Lighting units from which the sensing device senses modulated light are identified from the modulation of that modulated light. The sensing device measures the intensity of the modulated light from the identified lighting unit. The lighting sources are controlled dependent on control data which comprises measuring values of measured light intensities.

    Abstract translation: 控制包括控制器（2,10），照明单元（6）和感测装置的照明系统。 每个照明单元包括照明源（12）和调制光源（14）。 单个光源可以用作照明源和调制光源。 每个调制光源发射唯一调制的光。 每个调制光源的辐射图基本上与同一照明单元的照明源的辐射图案重合。 感测装置适于感测观看区域中的调制光。 从该调制光的调制中识别感测装置感测调制光的照明单元。 感测装置测量来自识别的照明单元的调制光的强度。 光源依赖于测量光强度的测量值的控制数据进行控制。

    Abstract: An illumination unit according to the invention comprises an electrodeless low-pressure discharge lamp (20) and a supply device (50). The lamp has a discharge vessel (30) which encloses in a gastight manner a discharge space (31) which is provided with an ionizable filling. The lamp (20) further has a coil (40) provided with a winding (42) around a sintered core (41) of polycrystalline ferrite material, which winding (42) is connected to the supply device (50). The coil (40) is capable of inducing a high-frequency magnetic field which maintains a discharge in the discharge space (31). The losses in the core (41), when measured at room temperature in a magnetic field with a frequency of 3 MHz and a magnetic flux density of 10 mT, amount to at most 150 mW/cm . This has the advantage that the lamp (20) ignites comparatively quickly and loads the supply device (50) comparatively weakly during ignition. The supply device (50) as a result can have a comparatively long useful life.
