US Patent 7798684 Luminaire system with thermal chimney effect

A luminaire system having an elongated throughway utilizing a thermal chimney effect. The thermal chimney effect within the throughway circulates air to remove heat generated from the electrical components of the system. Dissipating heat into the throughway from the electrical components can increase the life expectancy of the lamp and the output of the lamp. The electrical components of the system being entirely sealed and isolated from the throughway results in a permanent air, dust, and water tight seal. The permanent seal can minimize damage to the electrical components of the system as well as prevent the build up of moisture and dust within these sealed components.
