Taking the heat out of LED fixtures
Heat sinks, heat pipes and synthetic jets are among the technologies being used by LED fixture makers to remove heat from their products and enable them to operate correctly, reports Francoise Von Trapp.
Additionally, LED lighting fixtures often contain multiple LEDs, which can result in very high levels of dissipated power. Standard light fixtures with well-defined form factors tend to be restricted by size, which reduces the cooling capacity and necessitates innovative cooling solutions.
Designing for LEDs
Effective cooling of LED fixtures begins with a good design that generally includes some form of heatsink to remove the thermal energy from the fixture body. In many fixtures, the heatsink is an integral part of the housing design.
