Patent ID: 8398271

Claim:
A LED lamp with adjustable beam direction, the lamp comprising: (a) a housing; (b) a lamp base attached to one end of the housing for insertion into a lamp socket; (c) a heatsink shaft mounted within the housing which serves as a heatsink; (d) a LED attached to one end of the heatsink shaft; (e) a reflector comprising a light output front opening and an asymmetric elliptical shaped rear opening, the LED being disposed proximate to the rear opening; (f) a first actuator for rotating the reflector about the LED; and (g) a second actuator for tilting the reflector about the LED; wherein the first actuator comprises: a gear rotatable about the heatsink shaft; two arms comprising two ends fixedly connected to the gear and two opposite ends pivotably connected to a rear surface of the reflector by two pivot joints respectively; and a pan motor for rotating the gear and in turn rotating the reflector about a central longitudinal axis of the heatsink shaft; and wherein the second actuator comprises: a collar mounted around the heatsink shaft and movable along two columns connected to the housing and oriented generally parallel to the heatsink shaft, the collar comprising external threads and an inwardly and radially extending annular member; a collar-engaging member comprising a proximal end attached to the reflector and a distal end slidably engaged with the annular member; a cup gear comprising internal threads meshed with the external threads of the collar; and a tilt motor for rotating the cup gear, thereby driving the collar along the two columns, moving the distal end of the collar-engaging member radially relative to the annular member, and tilting the reflector about a pivot axis defined by the two pivot joints.
