Abstract
A high-powered lighting assembly includes an easily sealed continuous thermal barrier and a solid-state actively controlled closed-loop refrigeration system to maximize operational efficiencies and increase unit life. The thermal barrier prevents thermal back-flow from a heat sink plate or a housing to a lighting array while insulating a control module and a thermal sensor with improved sealing geometry. The refrigeration system is optimally positioned to controllably pump heat from the lighting array to the heat sink plate.
