LIGHTING UNIT WITH HEAT-DISSIPATING CHIMNEY
First Claim
1. A lighting unit comprising:
- a heat dissipating support structure, having at least one space between portions of the support structure;
a plurality of light emitting elements in thermal communication with the support structure and disposed along a length of said support structure; and
at least one passageway located between at least two light emitting elements and through the heat dissipating support structure to the space.

Abstract
The invention provides systems and methods for providing illumination. A lighting unit may have a support structure, and one or more light emitting elements supported by a circuit board contacting the support structure. A first optical element and a second optical element may be provided. A remote luminescent material may be provided on one or more optical elements. Light emitting elements configured to excite the luminescent material such as highly efficient light emitting diodes may be directed towards the luminescent material. The support structure may be a heat dissipating element, which may conduct heat from a heat source to a surface of the support structure. The heat dissipating element may have a passageway permitting the formation of a convection path to dissipate heat from the support structure. Such lighting units may be used to replace conventional fluorescent light tubes or other lighting devices, or may be provided as standalone lighting units.

12. A method of heat dissipation comprising:
-
providing a heat dissipating support structure, having at least one space between portions of the support structure; providing a plurality of light emitting elements in thermal communication with the support structure and disposed along a length of said support structure; and transferring heat from the light emitting elements to the heat dissipating support structure and the at least one space between portions of the support structure, thereby creating a convection path through the at least one space. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)
