Abstract: LED lamps are provided with cooling fan and heat sink units adapted from such units used in cooling computer components, which are engineered to provide long-life and exemplary cooling at a moderate cost and small size. Portable lamps, including flashlights, trouble lights, and lanterns, as well as threaded lamps, are provided with such cooling units and benefit from the compact, long-lived qualities of those units to preserve the LED units and allow them to achieve their longevity potential.

Abstract: LED lamp structures and lighting fixtures are provided, particularly “down” or recessed lighting fixtures, street lamp fixtures, “work-lights” and automobile headlights. A fan and a heat sink are provided with each lamp and the LED array is attached directly to the heat sink. The fans used preferably are computer cooling fans which are particularly small, efficient and inexpensive. The fans preferably force air through the fins sideways. The fans in some embodiments are recessed among the fins of the heat-sink so as to conserve space and obtain direct flow of air through the fins. The low-volume exhaust from the fans is released directly into the air space or housing in which the lamps are mounted without the need for special ducting, thus taking advantages of the naturally-occurring crevices and opening for all or part of air escape openings.
