Abstract
A flashlight is provided. The flashlight includes a LED light source, a power circuit that provides power to the LED light source and a buck and boost power controller within the power circuit in series with the LED light source where the buck and boost circuit boosts a battery voltage to the light source when the battery voltage is below the predetermined voltage and reduces the battery voltage to the light source when the battery voltage exceeds the predetermined voltage.
Claims19
A flashlight comprising:
- a cylindrical housing;
- a LED light source disposed on a first end of the housing with an axis of transmission of the LED parallel to the predominant axis of the light and baton housings;
- a rotatable mode selector cap extending axially from a second end of the housing and that rotates around a predominant axis of the housing;
- and
- a spring-loaded pushbutton extending axially from a distal end of the mode selector cap, the mode selector cap having a first position of rotation wherein the light source cannot be activated, a second position of rotation wherein the light source activates only so long as the pushbutton is activated and a third position of rotation wherein the light source transitions between an OFF to ON state or a ON to OFF state once each time the pushbutton is activated and released.

A flashlight comprising:
- a cylindrical housing having a predominant axis;
- a LED light source disposed on a first end of the cylindrical housing with an axis of light transmission parallel to the predominant axis of the cylindrical housing;
- an LED circuit board that supports the LED light source disposed between the light source and cylindrical housing perpendicular to the predominant axis of the housing;
- a power circuit board that controls power to the LED light source disposed between the first circuit board and the housing;
- a first connector plug disposed on the LED circuit board;
- and
- a second mating connector plug disposed on the power circuit board, the first and second connector plugs slidably engaging one another along the predominant axis of the cylindrical housing.

A flashlight comprising:
- a LED light source;
- a power circuit that provides power to the LED light source;
- a buck and boost power controller within the power circuit in series with the LED light source where the buck and boost circuit boosts a battery voltage to the light source when the battery voltage is below a predetermined voltage and reduces the battery voltage to the light source when the battery voltage exceeds the predetermined voltage to provide a longer run time for the flashlight a plurality of push-on electrical connector sets connecting the LED light source and buck and boost controller, each push-on electrical connector of the connectors sets further comprising a respective male and female connector that can be pulled apart and reconnected without tools;
- a cylindrical housing with the LED light source disposed on a first end of the housing and a rotatable mode selector cap extending axially from a second end of the housing and that rotates around a predominant axis of the housing to select a mode projection selected from the group consisting of an OFF projection, a momentary contact projection and a toggling projection, a spring-loaded pushbutton extending axially from a distal end of the mode selector cap, the mode selector cap having a first position of rotation wherein the light source cannot be activated, a second position of rotation wherein the light source activates only so long as the pushbutton is activated and a third position of rotation wherein the light source transitions between an OFF to ON state or a ON to OFF state each time the pushbutton is activated and released.
