ABSTRACT:
The invention concerns a light detection power system (105). The system can include a solar cell charging circuit (120) having at least one solar cell (116) in which the solar cell charging circuit can provide power to a power source (114), a lighting circuit (122) that receives power from the power source and a controller (118) coupled to the solar cell charging circuit and the lighting circuit. The controller can enable the lighting circuit when a power level that the controller detects from the solar cell charging circuit fails to reach a first predetermined threshold. The solar cell charging circuit can include a switch (130) that is controlled by the controller. The controller can further enable the switch when the power level that the controller detects from the solar cell charging circuit reaches a second predetermined threshold.
