Abstract

There is provided a lighting device ( 100 ) comprising at least one light source for providing light, a envelope encompassing said light source, a base to which said envelope is engaged, and a control means for adjusting the lighting settings of said lighting device. The control means are arranged for detecting a position in relation to the base of a point of reference being movably arranged on the lighting device. The lighting settings are adjusted in response to the detected position.

First claim

The invention claimed is:

1. A lighting device comprising:
at least one light source for providing light;
an envelope encompassing said light source;
a base to which said envelope is engaged;
a control means for adjusting the lighting settings of said lighting device, wherein said control means are arranged for detecting a position in relation to said base of a point of reference being movably arranged on said lighting device, and wherein said lighting settings are adjusted in response to said detected position; and
a control element to which said reference point is associated, wherein said control element is a capacitive touch sensor or non-contact sensor, wherein said capacitive touch sensor or said non-contact sensor is arranged by means of a transparent conductor on an inner or outer side of said envelope, and wherein the at least one light source is disposed at a distance from said envelope such that said at least one light source is remote from said control element.

2. A lighting device according to claim 1 , wherein said detected position is detected vertically, horizontally, or as a rotation about a central symmetry axis of the lighting device, or as any combination thereof.

3. A lighting device according to claim 2 , wherein said envelope is movably engaged with said base.

4. A lighting device according to claim 3 wherein said envelope further comprises an inner envelope arranged for encompassing said light source.

5. A lighting device according to claim 4 , wherein an optical layer is arranged on said inner envelope, wherein said optical layer is one of a remote phosphor layer, a segmented remote phosphor layer, and a micro-structure.

6. A lighting device according to claim 5 , wherein said envelope is releasably engaged with said base.

7. A lighting device according to claim 1 , wherein the at least one light source is disposed substantially at a symmetry axis of said envelope.

8. A lighting device according to claim 1 , wherein said envelope is spherically-shaped.

9. A lighting device according to claim 1 , wherein said envelope fully encloses the at least one light source.
