Abstract

A lighting device is provided, a plurality of light sources are located within a housing of the lighting device. A sensor is also provided to determine an indication of the point of lowest potential energy and/or the point of highest kinetic energy. This sensor output is input to a controller that is configured to determine a change in the position or a movement of the point of lowest potential energy and/or the point of highest kinetic energy as the position of the lighting device changes based on the sensor output and to change a property of the light emitted by the plurality of light sources based on the change of position or a movement of the point of lowest potential energy and/or the point of highest kinetic energy.

First claim

The invention claimed is:

1. A lighting device comprising:
a housing;
a plurality of light sources;
at least one sensor for determining an indication of the point of lowest potential energy for every position of the lighting device; and
a controller;
wherein the lighting device is moveable and wherein said controller is configured to determine, based on the indication of the point of lowest potential energy output by said at least one sensor, a change in the position or a movement of the point of lowest potential energy as the position of said lighting device changes and to provide a linear light effect by changing a property of the light emitted by the plurality of light sources in a flowing manner emulating a fluid flow, toward the point of lowest potential energy.

2. The lighting device of claim 1 wherein a rate of change of the property of the light emitted by the plurality of light sources is dependent on a rate of change of position or movement of the point of lowest potential energy.

3. The lighting device of claim 1 wherein said at least one sensor comprises at least one of an accelerometer, a gyroscope, a pressure sensor, an altimeter, an inclinometer or a gravity sensor.

4. The lighting device of claim 1 wherein a substantial surface area of said housing is curved.

5. The lighting device of claim 4 wherein said controller is configured to change at least one of a hue, a saturation and an intensity of the light emitted in the vicinity of a lowest point of said lighting device.

6. The lighting device of claim 5 wherein said controller is configured to increase either a saturation or an intensity of the light emitted in the vicinity of the lowest point of said lighting device.

7. The lighting device of claim 1 wherein the lighting device comprises an elongated lighting device.

8. The lighting device of claim 1 wherein the lighting device comprises an elongated housing, said elongated housing further comprising,
a first end A,
a second end B, and
a curved surface area between said first end A and said second end B.

9. The lighting device of claim 1 wherein the lighting device comprises a circular lighting device.

10. The lighting device of claim 9 wherein said lighting device comprises a planar circular lighting device.

11. The lighting device of claim 1 wherein the lighting device comprises a semi-spherical lighting device.

12. The lighting device of claim 1 wherein the lighting device comprises a spherical lighting device.

13. A method of controlling a light output of a plurality of light sources of a lighting device according to the steps of:
determining a point of lowest potential energy of the plurality of light sources based on an indication of the point of lowest potential energy for every position of the lighting device output by at least one sensor;
determining a change in the position or a movement of the point of lowest potential energy as the position of said lighting device changes; and
providing a linear light effect by changing a property of the light emitted by the plurality of light sources in a flowing manner emulating a fluid flow, toward the point of lowest potential energy.

14. A lighting device comprising:
a housing;
a plurality of light sources;
at least one sensor for determining an indication of the point of highest kinetic energy for every position of the lighting device; and
a controller operably coupled with the plurality of light sources and the at least one sensor;
wherein the lighting device is moveable and wherein said controller is configured to determine, based on the indication of the point of highest kinetic energy output by said at least one sensor, a change in the position or a movement of the point of highest kinetic energy as the position of said lighting device changes and to provide a linear light effect by changing a property of the light emitted by the plurality of light sources in a flowing manner emulating a fluid flow, toward the point of highest kinetic energy.

15. The lighting device of claim 14 wherein a rate of change of the property of the light emitted by the plurality of light sources is dependent on a rate of change of position or movement of the point of highest kinetic energy.

16. The lighting device of claim 14 wherein said at least one sensor comprises at least one of an accelerometer, a gyroscope, a pressure sensor, an altimeter, an inclinometer or a gravity sensor.

17. The lighting device of claim 14 wherein a substantial surface area of said housing is curved.

18. The lighting device of claim 17 wherein said controller is configured to change at least one of a hue, a saturation and an intensity of the light emitted in the vicinity of a lowest point of said lighting device.

19. The lighting device of claim 18 wherein said controller is configured to increase either a saturation or an intensity of the light emitted in the vicinity of the lowest point of said lighting device.

20. The lighting device of claim 14 wherein the lighting device comprises an elongated lighting device.
