Abstract:
1. A projector assembly comprising: a light source; a reflector body positioned proximately to the light source and adapted to reflect light forward generally along an assembly axis; a lens mounted to the reflector body and located forward of and at a distance from the light source, the lens being configured to focus light passing therethrough into a beam pattern generally along the assembly axis; an actuator having a pair of rotatable shafts extending from opposing ends of the actuator along a rotational axis, the rotational axis being generally perpendicular to and spaced apart from the assembly axis, wherein the actuator includes an actuator body that is directly mounted to the reflector body and at least partially within an interior of the reflector body; a light shield having a shield portion mounted to the rotatable shafts of the actuator, the light shield and the rotatable shafts being rotatable about the rotational axis between a first position or a second position, in the first position the shield portion extending substantially upward toward the axis of the projector assembly thereby blocking light below the assembly axis, in the second position the shield portion being rotated forward and downward relative to the assembly axis such that the shield portion is positioned below the assembly axis thereby allowing a portion of the light below the assembly axis to project forward through the lens, the light shield further including at least one tab extending away from the shield portion on an opposite side of the rotatable shafts and the rotational axis; and counterweights mounted onto the tabs, the counterweights located at a distance from the rotational axis such that the weight of the shield portion extending from one side of the rotatable shafts and the rotational axis is approximately equal to the weight of the counterweights and the tabs on the other side of the rotatable shafts and the rotational axis and such that a center of gravity of the light shield and the counterweights is located approximately on the rotational axis.
