Abstract

A light assembly is disposed about a core that is slidably and rotatably coupled to a frame. The frame has an interior volume that is shaped to receive the core therein. When the core is disposed within the frame, the light assembly is visible through the frame. In this manner, light propagated from the light assembly is propagated through an opening in the frame. The core can be moved longitudinally with respect to the frame and/or radially with respect to the frame. Light output increases as the core is moved with respect to the frame.

First claim

The invention claimed is:

1 . A hand-held lighting device, comprising:
a frame having an internal volume configured to house a core therein, the frame comprising a top, a bottom, and a plurality of arms, the plurality of arms connecting the top of the frame to the bottom of the frame; wherein the top comprises an opening for slidably receiving the core therein; a core slidably disposed within the frame, the core comprising a top, a bottom, and a lighting assembly disposed between the top and bottom of the core; wherein the lighting assembly comprises a plurality of light sources that are configured to selectively activate as the core is slidably moved with respect to the frame in a longitudinal direction and as the core is rotated with respect to the frame.

2 . The lighting device of claim 1 , further comprising a sensor assembly configured to detect longitudinal movement of the core within the frame and to increase the light output from the light assembly as the core is slidably removed from the frame and decrease the light output from the light assembly as the core is slidably placed within the frame.

3 . The lighting device of claim 1 , wherein the lighting assembly comprises a plurality of radial segments each comprising a plurality of light sources, wherein the light sources in the radial segments are selectively activatable as the core is rotate within the frame.

4 . The lighting device of claim 1 , wherein the lighting assembly comprises a plurality of vertical segments each comprising a plurality of light sources, wherein the light sources in the vertical segments are selectively activatable as the core is longitudinally moved within the frame.

5 . The lighting device of claim 1 , wherein the bottom of the core is configured to mate with the bottom of the frame when the core is fully disposed within the frame.

6 . The lighting device of claim 1 , wherein the top of the core is configured to mate with the top of the frame when the core is fully disposed within the frame.

7 . The lighting device of claim 1 , further comprising a strap coupled to a top of the core and the bottom of the frame.

8 . The lighting device of claim 1 , wherein the plurality of arms comprises a plurality of longitudinal arms extending from a top of the frame to a bottom of the frame in a longitudinal direction of the frame and wherein adjacent ones of the plurality of arms are separated by an opening into an internal volume of the frame.

9 . A hand-held lighting device comprising:
a frame having an internal volume configured to house a core therein, the frame comprising a top, a bottom, and a plurality of pairs of arms extending longitudinally between the top of the frame and the bottom of the frame, each pair of the plurality of arms defining an opening through the frame into the internal volume of the frame; wherein the frame comprises an opening for slidably receiving the core therein in a longitudinal direction; a core slidably disposed within the frame, the core comprising a top, a bottom, and a lighting assembly disposed between the top and bottom of the core; a sensor assembly coupled to the core and the frame; wherein the lighting assembly comprises a plurality of light sources that are configured to (i) selectively increase light output in along a longitudinal direction of the light assembly as the core is slidably moved with respect to the frame in a longitudinal direction and (ii) selectively increase light out put in a radial direction of the light assembly as the core is rotated with respect to the frame.

10 . The hand-held lighting device of claim 9 , wherein the lighting assembly comprises first and second opposing conical sections disposed between the top and bottom of the core.

11 . The lighting device of claim 9 , wherein the plurality of arms are translucent or transparent.

12 . The lighting device of claim 9 , wherein the bottom of the core comprises a tab configured to mate with an opening between one of the pairs of the plurality of arms, said tab limiting the radial and longitudinal movement of the core within the frame.

13 . The lighting device of claim 9 , wherein the sensor assembly is configured to detect longitudinal movement of the core within the frame and radial movement of the core within the frame.

14 . A method of operating a hand-held lighting device, comprising:
using a lighting device to propagate light, the lighting device comprising a core disposed within a frame, the core comprising a lighting assembly increasing the amount of light propagated by the lighting assembly along a longitudinal direction of the core by sliding the core of the lighting device out of a frame; increasing the amount of light propagated by the lighting assembly in a first radial direction of the core by rotating the core within the frame in the first radial direction.

15 . The method of claim 14 , further comprising:
decreasing the amount of light propagated by the lighting assembly in a longitudinal direction by sliding the core of the lighting device into the frame; decreasing the amount of light propagated by the lighting assembly in a radial direction by rotating the core within the frame in a second radial direction, the second radial direction being opposite the first radial direction.

16 . The method of claim 15 , wherein the lighting assembly comprises a sensor assembly operatively coupled to the core and the frame and configured to detect (i) longitudinal movement of the core into and out of the frame and (ii) rotation of the core within the frame.

17 . The method of claim 14 , wherein increasing the amount of light propagated by the lighting assembly in the longitudinal direction of the core comprises increasing the duty cycle of the light sources, increasing the voltage provided to the light sources, or increasing the number of light sources propagating light.

18 . The method of claim 14 , wherein increasing the amount of light propagated by the lighting assembly in the radial direction of the core comprises increasing the duty cycle of the light sources, increasing the voltage provided to the light sources, or increasing the number of light sources propagating light.

19 . The method of claim 15 , wherein decreasing the amount of light propagated by the lighting assembly in the longitudinal direction of the core comprises decreasing the duty cycle of the light sources, decreasing the voltage provided to the light sources, or decreasing the number of light sources propagating light.

20 . The method of claim 15 , wherein decreasing the amount of light propagated by the lighting assembly in the radial direction of the core comprises decreasing the duty cycle of the light sources, decreasing the voltage provided to the light sources, or decreasing the number of light sources propagating light.
