Optical sensor has region of LED chip facing lens with central light region and surrounding contact field connected by bonded wire to conducting track of circuit board

摘要

The optical sensor has a transmission element in the form of a LED chip (2) on a circuit board (1) and a transmission lens (3) associated with the transmission element. The region of the LED chip facing the lens has a central light region and a surrounding contact field that is connected by a bonded wire (6) to a conducting track of the circuit board.
