Abstract:
A lighting device system includes light emitters where a battery powers the light emitters. A battery supplies the power for powering the light emitters and a driver is arranged to selectively power the light emitters to adjust an operating parameter of the at least one light emitter based on the charge status of the battery. The driver may be in communication with a GNSS receiver that provides geospatial information used to adjust the at least one parameter. The driver may power the light emitters according to a non-adaptive light level profile and an adaptive light level profile where the light emitters consume less energy when operated under the adaptive light level profile than when operated under the non-adaptive light level profile. A processing device operatively coupled to memory determines, based on a state of charge of the battery, which profile to run.
