Abstract: Some embodiments are directed to a control system (140, 141, 142) for controlling a cooling fan used together with a motion detector. The controlling comprises controlling an activation and/or a rotation frequency of the cooling fan. The control system has a communication interface arranged for communication with the motion detector. The motion detector is configured to detect motion by emitting and receiving electromagnetic radiation and establishing frequency differences between the emitted and received electromagnetic radiation. The system operates the cooling fan at a regular rotation frequency and then, in response to obtaining a signal indicating that the motion detector is being used, adjusts the activation and/or the rotation frequency of the cooling fan, wherein said adjustment reduces an interference of the cooling fan with the frequency differences established by the motion detector.

Abstract: A semiconductor light emitting device comprising a light emitting layer disposed between an n-type region and a p-type region is combined with a ceramic layer which is disposed in a path of light emitted by the light emitting layer. The ceramic layer is composed of or includes a wavelength converting material such as a phosphor. Luminescent ceramic layers according to embodiments of the invention may be more robust and less sensitive to temperature than prior art phosphor layers. In addition, luminescent ceramics may exhibit less scattering and may therefore increase the conversion efficiency over prior art phosphor layers.
