Patent ID: 6951412

Claim:
A pivot stud assembly for use in a light assembly comprising a housing and a reflector, the pivot stud assembly comprising: a first member suitable for mounting to one of either the housing or the reflector, the first member having a ball of a generally ellipsoid shape with a first axis and a second axis, and a socket suitable for mounting to one of either the housing or the reflector so that the socket is placed opposite of the first member, the socket being sized to receive and engage the ellipsoid ball of the first member to form a joint which allows rotation only about the first axis, such that when the ellipsoid ball is engaged with the socket, and the pivot stud assembly is installed into a light assembly having an aim point, rotation of the light assembly about the first axis causes the light assembly aim point to move in the vertical plane, and such that when the ball is engaged with the socket, and the pivot stud assembly is installed into a light assembly having an aim point, the aim point of the light assembly cannot rotate about the second axis.
