Abstract
A substrate having a plurality of light emitting diodes united therewith lies on a plane containing the longitudinal axis of an insertion unit of an endoscope. Likewise, part of a first objective surface lies on the plane containing the longitudinal axis of the insertion unit of the endoscope. As long as the diameter of the insertion unit remains unchanged, the plane containing the longitudinal axis of the insertion unit of the endoscope provides the largest area for the light emitting diodes. The light emitting diode sub-assembly is therefore placed on this plane, so that the outer diameter of a distal endoscope part can be made as small as possible.
