Abstract
A lamp assembly comprises at least one light source such as a high-power LED (106), a housing (heat sink (108), metal base (109) with holes (126), lens (118)) in or on which the light source is located, and a fan (120) adapted to produce a current of air to cool the light source. The fan is arranged to draw air away from the light source through the holes (126) and to eject it from the housing; to this end the fan is preferably located directly underneath the light source in a self-contained package.
