Abstract: The present disclosure discloses an illumination device, including a first lamp body; a driving power supply component received in the first lamp body; a connecting element assembled into the first lamp body; a second lamp body connected to the connecting element and rotatable with respect to the first lamp body; a light source component received in the second lamp body; a second light distribution element received in the second lamp body and configured to perform a secondary light distribution to a part of light emitted from the light source component; and a first light distribution element disposed on the first lamp body and configured to perform a secondary light distribution to a second part of the light emitted from the light source component.

Abstract: The ball socket assembly includes a housing with an open interior which extends along an axis. A bearing is disposed in the open interior of the housing and has a curved primary contact surface which surrounds the axis and surrounds a stud ball opening. A stud ball is disposed in the opening and is in sliding contact with the primary contact surface for allowing rotation of the stud ball relative to the bearing. The stud ball has an equator and is in sliding contact with the bearing on both sides of the equator. A stud is operably connected with the stud ball. A shoe is further provided and has a pair of supplemental contact surfaces that are biased against the stud ball. The shoe provides the stud with a predetermined rotational torque and also adjusts for wear in the assembly to maintain the performance of the socket assembly.
