Abstract: The invention relates to a method for measuring a light radiation (300) emitted by a light-emitting diode (210). In the method, an end (121) of an optical fiber (120) which is connected to a measuring device (130) is irradiated with the light radiation (300), which is emitted by the light-emitting diode (210), through an optical device (140), so that a portion of the light radiation (300) is coupled into the optical fiber (120) and is guided to the measuring device (130). The optical device (140) causes the light radiation (300) passing through the optical device (140) to be emitted in diffuse form in the direction of the end (121) of the optical fiber (120). The invention also relates to an apparatus (100) for measuring a light radiation (300) emitted by a light-emitting diode (210).

Abstract: A lighting device comprising a phosphor wheel configured such that it temporarily sequentially not only emits the excitation light in a wavelength-converted fashion as conversion light but additionally reflects said excitation light in an unconverted fashion as reflection light. Conversion light and reflection light are guided spatially separately on a conversion light path and reflection light path, respectively, with the aid of a first dichroic mirror and are finally combined with the aid of a second dichroic mirror. In this way, it is possible to combine the reflection light for example as a blue light channel with the conversion light.
Abstract: Techniques are disclosed for selective use of light-sensing devices in light-based communication (LCom). In accordance with some embodiments, the disclosed techniques can be used, for example, in determining how and when to utilize a given light-sensitive device, such as a camera or an ambient light sensor, of a receiver device for purposes of detecting the pulsing light of LCom signals transmitted by an LCom-enabled luminaire. In accordance with some embodiments, determination of whether to utilize only a camera, only an ambient light sensor, or a combination thereof in gathering LCom data may be based, in part or in whole, on factors including time, location, and/or context. In some cases, improvements in system resource usage may be realized using the disclosed techniques.

Abstract: A circuit arrangement includes a converter having a converter switch and a driver for the converter switch. The driver includes an interface coupling to a dimming apparatus supplying a dimming value. The driver provides an RF signal with a duty ratio at the output of the driver. The driver modifies the RF signal by superposition of a PWM signal such that, in correlation with the supplied dimming value, a predefinable number of periods of the RF signal is chopped from the RF signal. The driver is configured to reduce the duty ratio of the RF signal during at least one predefinable period of the RF signal in order to adjust levels of dimming which correspond to dimming values which are between a first and a second dimming value which differ from one another by at least one period of the RF signal.
