Abstract

An elongated, slimline structure having a monolithically fabricated heatsink core and heat dissipating fins, coupled to a light source wherein the elongated structure substitutes for a light source retained by a luminaire housing.

First claim

The invention claimed is:

1. A monolithic linear heatsink comprising:
a solid or substantially solid core having a longitudinal opening that extends along a length of the core;
a plurality of heat dissipating fins extending outwardly from an exterior surface of the core, wherein the exterior surface of the core defines at least one flat surface;
at least one light source disposed on the at least one flat surface of the core; and
a power or a power and data conductor extending through the longitudinal opening of the core, wherein heat generated by the at least one light source directly propagates radially and contemporaneously through a solid portion of the core to two or more of the heat dissipating fins coupled to the core, wherein a first area of the solid portion of the core is greater than a second area of the longitudinal opening of the core, and wherein the first area and the second area are measured at a section along axis transverse to the length of the core.

2. The heatsink of claim 1 , further comprising at least two conductors retained by the core and electrically engaging an external detachable device.

3. The heatsink of claim 1 , further comprising a device coupled to the at least one light source, wherein the device augments natural light distribution pattern of the at least one light source.

4. The heatsink of claim 1 , further comprising a light source driver coupled to the core.

5. The heatsink of claim 1 , wherein the power or the power and data conductor conveys power or power and data to at least one conductor of another heatsink.

6. The heatsink of claim 1 , further comprising an externally mounted detachable electronic device having sensing, communication, and/or processing capabilities.

7. The heatsink of claim 1 , further comprising at least one bracket configured to engage at least one of the heat dissipating fins to mechanically support the core, wherein the bracket is movable along a length of the at least one of the heat dissipating fins.

8. A monolithic linear heatsink comprising:
a solid or substantially solid core;
a plurality of heat dissipating fins extending outwardly from an exterior surface of the core, wherein the exterior surface of the core defines at least one flat surface;
at least one light source disposed on the at least one flat surface of the core; and
a power or a power and data conductor is conveyed thorough at least one of at least one partial or full enclosure defined by at least one of the plurality of heat dissipating fins and a longitudinal opening of the core, wherein heat generated by the at least one light source propagates radially and contemporaneously through a solid portion of the core to two or more of the heat dissipating fins coupled to the core, wherein a first area of the solid portion of the core is greater than a second area of the longitudinal opening of the core, and wherein the first area and the second area are measured at a section along axis transverse to the length of the core.

9. The heatsink of claim 8 , further comprising at least two conductors retained by the core and electrically engaging an external detachable device.

11. The heatsink of claim 8 , further comprising a light source driver is coupled to the core.

12. The heatsink of claim 8 , wherein the power or the power and data conductor conveys power or power and data to at least one conductor of another heatsink.

13. The heatsink of claim 8 , further comprising an externally mounted detachable electronic device having at least one of sensing, communication, and/or processing capabilities.

14. The heatsink of claim 8 , further comprising at least one bracket configured to engage at least one of the plurality of heat dissipating fins to mechanically support the core, wherein the bracket is movable along a length of the at least one of the plurality of heat dissipating fins.

15. A monolithic linear heatsink comprising:
a solid or substantially solid core;
a plurality of heat dissipating fins extending outwardly from an exterior surface of the core, wherein the exterior surface of the core defines at least one flat surface;
at least one light source disposed on the at least one flat surface of the core, wherein heat generated by the at least one light source propagates radially and contemporaneously through a solid portion of the core to two or more of the plurality of the heat dissipating fins coupled to the core; and
at least one externally mounted detachable device mechanically and/or electromechanically coupled to the exterior surface of the core, wherein a first area of the solid portion of the core is greater than a second area of the longitudinal opening of the core, and wherein the first area and the second area are measured at a section along axis transverse to the length of the core.

16. The heatsink of claim 15 , further comprising at least two conductors retained by the core and electrically engaging the externally mounted detachable device.

17. The heatsink of claim 15 , further comprising a device coupled to the at least one light source that augments a natural light distribution pattern of the at least one light source.

18. The heatsink of claim 15 , further comprising a light source driver coupled to the core.

19. The heatsink of claim 15 , further comprising a power or a power and data conductor that conveys power or power and data to at least one conductor of another heatsink.

20. The heatsink of claim 15 , wherein the externally mounted detachable electronic device includes at least one of sensing, communication and/or processing capabilities.

21. The heatsink of claim 15 , further comprising at least one bracket engaging at least one of the plurality of heat dissipating fins, wherein the at least one bracket is movable along a length of the at least one of the plurality of heat dissipating fins.

22. A method comprising:
providing a linear heatsink including
a solid or substantially solid core,
a plurality of heat dissipating fins extending outwardly from an exterior surface of the core, wherein the exterior surface of the core defines at least one flat surface, and wherein the exterior surface of the core retains electrified and/or non-electrified devices, and
at least one light source disposed on the at least one flat surface of the core;
supporting the linear heatsink from at least one selectable support point along a length of the linear heatsink, wherein the linear heatsink includes a structural member that retains electronic devices and conveys power or power and data; and
conveying power or power and data to at least one of: a) a light source; b) at least one of the electronic devices; c) a light source and at least one of the electronic devices; or d) a light source, at least one of the electronic devices, and at least one other light source and/or electronic device coupled to another linear heatsink, wherein conveying power or power and data is through at least one longitudinal opening in the core of the linear heatsink, through an opening defined by at least one of the plurality of heat dissipating fins, or via a combination thereof, wherein conveying power or power and data is along a length of the linear heatsink from one end of the linear heatsink to another end of the linear heatsink, wherein a first area of a solid portion of
