Solid state low bay light with integrated and sealed thermal management
Abstract:
A lighting fixture utilizing LED light sources for illumination of commercial, outdoor and other large area applications incorporates efficient heat dissipation and improved convective air flow. An integrated heat transfer assembly is disclosed that is configured to enhance heat dissipation by providing an efficient thermal conductive pathway for radiation of heat to an external environment. The lighting fixture body is configured with a lens body and heat sink having a chimney tube with internally facing finned heat sink arrangement for providing enhanced convective air flow through the light fixture body. When the heat sink transfers heat from the LED light sources during operation so as to create heated air surrounding the heat sink, ambient air is drawn through the chimney and the heated air is exhausted through air gaps so as to create a conductive air current with the environment. The heat sink fins are configured to enhance the natural air draw through the chimney by tapering the surface areas of the fins.
