  • Publication number: 20160123571
    Abstract: The disclosure relates to an illumination apparatus configured to expel internally-generated heat to keep light sources operating within a desirable temperature range to prevent damage to and prolong the operational life of the light sources. To effectuate heat removal, the apparatus includes a tubular structure defining a channel interposed between first and second ports, wherein the light sources are thermally coupled to the tubular structure. During operation, the light sources generate light and heat. The tubular structure is configured to draw the heat from the one or more light sources. The heat drawn by the tubular structure produces air convection within the channel such that air moves from the second port to the first port by way of the channel, or moves from the first port to the second port by way of the channel. One or more fans may be provided to generate forced air through the channel of the tubular structure.
