A lighting system () is provided that includes at least one lighting device (A,B,C), a plurality of external power sources () and an internal power source () applying a first electrical current to illuminate at least one lighting source (A,B,C), wherein the internal power source () supplies the first electrical current. Further, a fuel gauging system and method () detects an electrochemical composition of a power source (), which can be at least one of the internal power source () and the external power source (), and then determines a state of charge of the power source () based upon the determined electrochemical composition of the power source ().

Fuel gauging system and method thereof

Modular power and lighting device

A light device is provided that includes a light source and electrical circuitry for supplying electrical power to the light source. The light device also includes a housing having first and second ends and a hollow interior defining a compartment for holding a power source. The housing comprises a woven fiber thermoset composite. The housing is made by applying woven fibers to a mandrel and impregnating the woven fibers with an epoxy and curing the epoxy impregnated woven fibers to form the thermoset composite housing. An electrical interconnect is provided within the housing having first and second resilient contacts for providing an electrical connection between the power source and the light source.

Method of manufacturing a housing for a light device

A lighting device includes a first lighting source, a second lighting source, and a controller. The first lighting source yields a first illumination pattern. The second lighting source yields a second illumination pattern. The patterns overlay to yield a third illumination pattern. The controller shifts available power between the first lighting source and the second lighting source.

Lighting device having cross-fade and method thereof

A lighting system is provided that includes at least one lighting device, at least one connector, and a plurality of external power sources. The at least one lighting device includes at least one lighting source, and an internal power source applying a first electrical current to illuminate the at least one lighting element, wherein the internal power source supplies the first electrical current. The at least one connector electrically connects to the at least one lighting device. The plurality of external power sources include at least first and second external power sources that are adapted to be electrically connected to the at least one lighting device by the at least one connector. Further, a fuel gauging system and method detects an electrochemical composition of a power source, which can be at least one of the internal power source and the external power source, and then determines a state of charge of the power source based upon the determined electrochemical composition of the power source.

Lantern lighting device

A lighting system is provided that includes at least one lighting device, at least one connector, and a plurality of external power sources.
