Opto electronic device has a light emitting diode set into a dish space with surface coated with metallised layer to act as a reflector

摘要

The opto electronic chip [50], eg a light emitting diode, is set at the centre of a dish shaped recess [12] formed in an insulating material. The surface is coated with a metallic reflective material. An isolating section [2] is used to form two reflective regions [16,18]. Connections are made with bond wires [35,52].
