| Title: |
LED-Based Fixtures and Related Methods for Thermal Management |
| Abstract: |
LED-based lighting fixtures suitable for general illumination in
surface-mount or suspended installations, in which heat dissipation
properties of the fixtures are significantly improved by decreasing
thermal resistance between LED junctions and the ambient air. In various
examples, improved heat dissipation is accomplished by increasing a
surface area of one or more heat-dissipating elements proximate a
trajectory of air flow through the fixture. In one aspect, various
structural components of the fixtures are particularly configured to
create and maintain a "chimney effect" within the fixture, resulting in a
high air-flow rate, natural convection cooling system capable of
efficiently dissipating the waste heat from the fixture without active
cooling.
