Systems and methods for multi-state power management
First Claim
1. A lighting fixture configured to manage power use, the lighting fixture comprising:
- one or more lighting elements;
one or more inputs, an input of the one or more inputs comprising a voltage input coupled to the one or more lighting elements, a controller, and a battery, the voltage input configured to provide power to the one or more lighting elements; and
the controller controlling the one or more lighting elements, the controller configured to;
receive measurements of voltage at the voltage input coupled to the one or more lighting elements;
determine changes to a battery status based on differences in the measurements of voltage at the voltage input coupled to the one or more lighting elements; and
control an intensity level of the one or more lighting elements based on the battery status.

Abstract
The present disclosure is directed to a solution providing multi-state power management. In some aspects, the design of the multi-state power management system (MPMS) facilitates switching to battery back up power upon identifying a power outage and further controlling the intensity level of a load (e.g., a light source) such that the light run time meets a minimum required run time. The MPMS may be designed and configured to identify a power outage and a battery status based on the voltage at a voltage input of the lighting device. The design may also include controlling the intensity level of the light source responsive to temperature measurements, e.g., ambient temperature or the temperature of one or more components, to maintain the health of the system.
