Putting cup system

Abstract

A putting cup includes an exterior housing configured to be disposed within a putting hole on a putting green and an interior core configured to be inserted into and attached to the exterior housing while the exterior housing is disposed within the putting hole. At least a portion of the interior core is at least partially translucent and defines an interior compartment for housing electronic components for illuminating the interior core. The electronic components include at least one battery electrically coupled to a printed circuit board, at least one light-emitting diode electrically coupled to the PCB and a dimmer circuit for periodically interrupting electrical power to the at least one LED to extend the battery life. A custom tool attaches the interior core to the exterior housing and detaches the interior core from the exterior housing while the exterior housing is disposed within the putting hole on the putting green.
