Portable lighting devices

摘要

A portable lighting device having a plurality of modes of operation and method of operating the portable lighting device are disclosed. One method of operating the portable lighting device is by rotating the portable lighting device along a principal axis of projection of the light source to enter into a new mode of operation. Normal, dim, motion sensitive, variable brightness, blink, right and left hand, lock out, SOS, night light, strobe, compass and signal modes are disclosed, and the modes may be adjusted. A rechargeable battery pack is disclosed that includes a housing, a rechargeable battery, and an accelerometer. A battery cassette is disclosed that provides a negative electrode at each end of the battery cassette, and a central connector that provides a positive electrode at both ends of the battery cassette.

主权项

1. A multi-mode portable electronic lighting device, comprising:
a housing including a source of power; a light source electrically connected to the source of power which emanates light away from the housing toward a plane along a principal axis of projection that is perpendicular to the plane at a point of intersection with the plane when an on/off switch is not in an off state; a controller configured to implement a plurality of modes of operation of the light source along the principal axis of projection when the on/off switch is not in the off state and a momentary switch is actuated; and a user interface for inputting commands to the controller, wherein the user interface comprises a motion sensitive interface in which commands are input through a first predefined movement of the portable electronic lighting device; wherein the controller will not change operation of the light source between the plurality of modes of operation when the on/off switch is not in the off state and the momentary switch is not actuated; wherein the controller is configured to change a mode of operation of the light source when the controller determines that the multi-mode portable electronic lighting device has been moved in the first predefined movement, so that the light source operates in a changed mode of operation; and wherein the controller is further configured to adjust light output of a given mode of operation of the light source when the controller determines that the multi-mode portable electronic lighting device has been moved in a second predefined movement when the on/off switch is not in the off state and the momentary switch is not actuated.
