ABSTRACT:
The invention relates to an optoelectronic arrangement which has a transmission component which emits electromagnetic radiation, a receiving component which detects a portion of the radiation emitted from the transmission component, and a transparent material which at least partially surrounds the transmission component and the receiving component and provides a boundary surface between the arrangement and the environment. In this case, a portion of the light which is emitted from the transmission component is reflected in the transparent material and/or on the boundary surface of the transparent material, and is detected by the receiving component. The invention also relates to a method for controlling the output power of a transmission component by means of a receiving component which detects a portion of the radiation which is emitted from the transmission component.
