发明名称 Line guide projector
摘要 A line projector (10) embodying the concepts of the present invention is employed to project a vane of light onto a work surface (16). The line projector is contained within a housing (12) that is mounted, as on the truss arrangement (13), in spaced relation from the work surface (16). The structure by which the housing (12) is supported may include a fixed connector assembly (52) or an adjustably movable carriage connector (70) by which to effect in gross movement of the line projector (10) along the supporting truss (13). A lamp (100) having a linear filament (122) is mounted within the housing (12), and it is the image of the filament (122) that is projected as the vane of light onto the work surface (16). A particularly unique pedestal arrangement (140) is employed demountably to support the lamp (100) as well as selectively to translate and/or skew the lamp relative to the housing (12).
