发明名称 Remote controlled spotlight system
摘要 A remote controlled spotlight system having a pair of spotlights on the ends of a horizontal shaft extending through a housing. A vertical shaft extends out of the housing for mounting purposes. An electric motor in the housing rotates the horizontal shaft about its longitudinal axis to aim the spotlights up or down. A second electric motor in the housing rotates the housing about the longitudinal axis of the vertical shaft to aim the spotlights left or right. The electrical motors are remotely controlled. An electrical power cord extends through the bore of the horizontal shaft, out through a hole in the horizontal shaft, and winds around the horizontal shaft at least twice. The cord then winds around the vertical shaft at least twice, and then passes through the bore of the vertical shaft to a power source.
