Abstract

Embodiments relate to a lighting device that includes or retains a plurality of solid-state light emitters and is capable of providing one or more of omni-directional lighting and task lighting. Other embodiments relate to modular lighting systems for providing the same.

Claims

1. A lighting device, comprising:

an illuminated body that includes or retains a first plurality of solid-state light emitters oriented to provide omni-directional lighting and a second plurality of solid-state light emitters oriented to only provide light extending in substantially one direction;

a first electric circuit connected to provide power to the first plurality of solid-state light emitters;

a second electric circuit connected to provide power to the second plurality of solid-state light emitters; and

a multi-throw switch coupled to selectively provide power to the first plurality of solid-state light emitters, the second plurality of solid-state light emitters, or both the first plurality of solid-state light emitters and the second plurality of solid-state light emitters.

2. The lighting device of claim 1, further comprising a third plurality of solid-state light emitters connected to both the first circuit and the second circuit.

3. The illuminated body of claim 1, further comprising two or more surfaces wherein one or more of the two or more surfaces includes or retains at least a portion of solid-state light emitters from the first plurality of solid-state light emitters, wherein the first surface is offset from the second surface.

4. The lighting device of claim 1, further comprising a second illuminated body that includes or retains at least one solid-state light emitter, wherein the at least one solid-state light emitter is connected with at least one of the first circuit and the second circuit.

5. The lighting device of claim 4, wherein the second illuminated body is positioned offset from the illuminated body.

6. The lighting device of claim 1, wherein at least one of the first plurality of solid-state light emitters emits light in a non-planar and non-parallel direction to at least one of the second plurality of solid-state light emitters.

7. The lighting device of claim 1, further comprising a third circuit connecting the first circuit to the second circuit.

8. The lighting device of claim 1, wherein actuating the multi-throw switch between a plurality of settings energizes no electric circuits, the first electric circuit, the second electric circuit, or both the first electric circuit and the second electric circuit.
