LED lighting device with adaptive profiles for controlling power consumption

A lighting device system comprising:

• at least one light emitter;
• a battery for powering the at least one light emitter;
• a memory;
• and
• a processing device operatively coupled to the memory, wherein the processing device is configured to:
• implement a non-adaptive light level profile for controlling the at least one light emitter, the non-adaptive light level profile comprising a plurality of light levels;
• determine if a state of charge of the battery is sufficient to run the non-adaptive light level profile;
• implement an adaptive light level profile for controlling the at least one light emitter if the state of charge of the battery is not sufficient to run the non-adaptive light level profile, the adaptive light level profile comprising a plurality of light levels, where the at least one light emitter consumes less energy when operated under the adaptive light level profile than when operated under the non-adaptive light level profile.

A method of operating a lighting device system comprising at least one light emitter and a rechargeable battery for powering the at least one light emitter, the method comprising:

• controlling the at least one light emitter using a non-adaptive light level profile where the non-adaptive light level profile requires a first amount of energy, the non-adaptive light level profile comprising a plurality of light levels;
• determining if a state of charge of the battery is sufficient to run the non-adaptive light level profile;
• controlling the at least one light emitter using an adaptive light level profile if the state of charge of the battery is not sufficient to run the non-adaptive light level profile where the non-adaptive light level profile requires a second amount of energy that is less than the first amount of energy, the adaptive light level profile comprising a plurality of light levels;
• calculating at least one of the adaptive light level profile and the non-adaptive light level profile using a geospatial location of the at least one light emitter.
