Control of a vehicle-mounted lighting system

A method of controlling a lighting system, the method comprising:

• receiving, with a power supply interface of the lighting system, power from a power source of a vehicle to which a lighting device of the lighting system is mounted, the lighting device including a lighting element configured to illuminate an area, wherein the power source of the vehicle includes an alternator of the vehicle;
• providing, with the power supply interface, power to the lighting device, a battery pack of the lighting system, or both the lighting device and the battery pack, the battery pack being configured to provide power to the lighting device;
• receiving, with a second electronic processor of the lighting system via a communication interface of the lighting system, onboard diagnostic information from a first electronic processor of the vehicle;
• and
• controlling, with the second electronic processor and based on the onboard diagnostic information, an amount of power drawn by the power supply interface from the power source of the vehicle;
• wherein the power supply interface includes charging circuitry configured to charge the battery pack;
• wherein the onboard diagnostic information includes at least one of a group of rotations per minute (“RPM”) of an engine of the vehicle, a speed of the vehicle, an acceleration of the vehicle, a position of a gear shifter of the vehicle, a pedal position of the vehicle, or combinations thereof;
• and
• wherein the method further comprises:
• determining, with the second electronic processor and based on the onboard diagnostic information, whether the vehicle is moving
• inhibiting, with the second electronic processor, power from being supplied to the lighting element in response to determining that the vehicle is moving, and
• controlling, with the second electronic processor, the power supply interface to charge the battery pack in response to determining that the vehicle is moving such that the amount of power drawn by the power supply interface to charge the battery pack is proportional to the RPM of the engine of the vehicle until the power drawn reaches a predetermined threshold.

A lighting system comprising:

• a lighting device mountable to a vehicle, wherein the lighting device includes a lighting element configured to illuminate an area;
• a battery pack configured to provide power to the lighting device;
• a power supply interface configured to receive power from a power source of the vehicle and configured to provide power to the battery pack, the lighting device, or both the battery pack and the lighting device, wherein the power supply interface includes charging circuitry configured to charge the battery pack;
• a communication interface configured to communicate with a first electronic processor of the vehicle;
• and
• a second electronic processor configured to;
• receive, via the communication interface, onboard diagnostic information from the first electronic processor of the vehicle, wherein the onboard diagnostic information includes at least one of a group of rotations per minute (“RPM”) of an engine of the vehicle, a speed of the vehicle, an acceleration of the vehicle, a position of a gear shifter of the vehicle, a pedal position of the vehicle, or combinations thereof,
• determine an operational characteristic of the vehicle, and
• control, based on the operational characteristic, an amount of power drawn by the power supply interface from the power source of the vehicle by:
• determining whether the vehicle is moving based on the operational characteristic of the vehicle,
• inhibiting power from being supplied to the lighting element in response to determining that the vehicle is moving, and
• controlling the power supply interface to charge the battery pack in response to determining that the vehicle is moving such that the amount of power drawn by the power supply interface to charge the battery pack is proportional to the RPM of the engine of the vehicle until the power drawn reaches a predetermined threshold.
