Led luminaire thermal management system

Abstract

A thermal management system for led luminaires that, in certain embodiments, includes a heat sink, a heat-dissipating pipe, a base plate, a variable speed air-cooling element, an air-directing structure, a temperature measuring element, and a driver that includes at least one of thermal sensing response logic, light-emitting dimming control logic, fan speed control logic and air-cooling element malfunction detection logic. In some instances, the heat sink includes a plurality of fins coupled to a base plate. In some instances, one or more heat-dissipating pipes extend partially inserted along the length of the base plate and outwardly away from an end of the base plate. In some embodiments, an LED PCB assembly is coupled to the base plate. In some embodiments, fan speed variability, LED dimming, or both are engaged in combination with heat transfer and dissipation associated with the heat sink and the one or more heat-dissipating pipes.

What is claimed is: 
     
         1 . A thermal management system for LED luminaires comprising:
 (i) a programmable driver comprising at least one of a thermal-sensing response logic, a light-emitting dimming control logic, an air-cooling element speed control logic, and an air-cooling element malfunction detection logic;   (ii) a temperature measuring element electrically coupled to the programmable driver; and   (iii) a variable speed air-cooling element comprising an air intake portion located proximal to the programmable driver, the variable speed air-cooling element electrically coupled to the programmable driver.
