Portable lighting devices

摘要

A portable lighting device with a main power circuit for electrically connecting a light source to a portable source of power, the main power circuit including an electric power switch disposed electrically in series with the light source, there also being an inertial sensor and a controller electrically coupled to the portable source of power, the controller including an output for providing a control signal for controlling the flow of power through the electronic power switch and the light source in the main power circuit, the controller also being electrically connected to the inertial sensor, wherein the controller is configured to control the flow of power through the electronic power switch based on one or more signals received from the at least one output of the inertial sensor.

1. A portable lighting device configured to operate using a portable source of power, the portable lighting device comprising:
a light source; a main power circuit for electrically connecting the light source to the portable source of power, the main power circuit including an electric power switch disposed electrically in series with the light source; an inertial sensor having at least one output; and a controller electrically coupled to the portable source of power, the controller including an output for providing a control signal for controlling the flow of power through the electronic power switch and the light source in the main power circuit, the controller also being electrically connected to the at least one output of the inertial sensor, wherein the controller is configured to control the flow of power through the electronic power switch based on one or more signals received from the at least one output of the inertial sensor; wherein the controller is configured to control the electronic power switch in a manner to provide at least two modes of operation, and wherein the controller is configured to switch to a new mode of operation when the controller determines that the portable lighting device has been moved in a first predetermined manner based on the one or more signals received from the at least one output of the inertial sensor; and wherein the controller is configured to adjust at least one mode of operation when the controller determines that the portable lighting device has been moved in a second predetermined manner.
