The ceramic layer includes a wavelength converting material and the light emitting diode is disposed between the ceramic layer and the mounting substrate. The light module package also includes a light sensor disposed at the mounting substrate for detecting a luminous output of the light emitting diode in order to control the brightness and/or the color of the light leaving the light module. The ceramic layer is only partly translucent to shield the light sensor against ambient light.

Abstract: The proposed invention application describes a novel configuration of an extremely small self-locking switching component, based on micro-electromechanical systems (MEMS) technology. Conventional MEMS switches need a continual control signal in order to obtain the wanted active (switching) state. The proposed invention needs only a short control signal (non-locking key) such as e.g. a pulse in order to switch the component on and/or off. RF-noise (ripples) on the de-control signal or bouncing effects can be neglected according to the proposed extension of the MEMS devices. This contributes to an easier and especially more robust design of electronic circuitries and allows for enhanced functionalities.
