Abstract
Various structures are provided that may be advantageously used in one or more illumination device designs. In one example, a lens is movable among a plurality of light sources to facilitate selection of which light source is used to provide light for the illumination device. In another example, electric power is provided only to the light source that is used to provide light for the illumination device. Rotation of a bezel of the light source can determine which light sources provides light for the light source and which light source receives electric power.
Claims25
A device comprising:
- a plurality of light sources;
- a bezel offset from a centerline of the device and configured to rotate eccentrically about the centerline;
- and
- a lens substantially concentric with the bezel and configured to rotate with the bezel eccentrically about the centerline from a first position proximate a first one of the light sources to a second position proximate a second one of the light sources, wherein the lens is configured to receive light from the first one of the light sources when in the first position and receive light from the second one of the light sources when in the second position.
A device comprising:
- a plurality of light sources;
- a bezel offset from a centerline of the device and configured to rotate eccentrically about the centerline;
- a lens substantially concentric with the bezel and configured to rotate with the bezel eccentrically about the centerline from a first position proximate a first one of the light sources to a second position proximate a second one of the light sources, wherein the lens is configured to receive light from the first one of the light sources when in the first position and receive light from the second one of the light sources when in the second position;
- a magnet attached to the bezel;
- and
- at least one Hall effect sensor configured to sense a position of the magnet to facilitate switching of electric power between the light sources.
A method for switching between light sources of a device, the method comprising:
- rotating a bezel of the device, wherein the bezel is offset from a centerline of the device and configured to rotate eccentrically about the centerline;
- wherein the rotating the bezel causes a lens of the device to rotate with the bezel eccentrically about the centerline from a first position proximate a first one of the light sources to a second position proximate a second one of the light sources;
- wherein the lens receives light from the first one of the light sources when in the first position and receives light from the second one of the light sources when in the second position;
- and
- wherein the lens is substantially concentric with the bezel.
