Abstract
A light dimming apparatus for dimming light output generated by a light source. A rectangular frame supports sets of blade members at a central aperture defined by the frame. The blade members of a set are positioned side-by-side, and adjacent ones of the blade members are hingedly connected together. Accordion-like movement of the blade members is provided responsive to application of forces applied to the blade members. A component of the applied forces causes linear translation of the blade members in to or out of the central aperture.
