Abstract
An LED lamp employing active cooling chambers is presented. The lamp features a housing having two active cooling chambers. One chamber, i.e. the first or cold chamber, contains an LED driver and one or more cooling fans, while the second chamber, i.e. the hot chamber, contains one or more LED modules secured to a heat sink. Fluid (air) communication between the two chambers is controlled by the one or more cooling fans. In operation, the fans draw ambient cooling air inside the cold chamber via air intake openings in the housing. The cooling air is then forced through a plurality of heat sink fins and heat transfer channels and exhausted from air exhaust openings in the housing.
