Adjustable optical reflector for fluorescent fixture
First Claim
1. An adjustable specular reflector, comprising;
- a plurality of planar facets in edge adjacent relationship, hinge means for joining each of said facets in pivotting fashion with respect to adjacent facets, said facets adapted to define together a contiguous, generally concave surface, a specular reflective layer adhered to said surface, means for maintaining said facets in selectively variable angular relationships, and a plurality of self-adhesive patches secured to the surface of said reflector opposed to said contiguous concave surface, said patches being disposed to be secured to the inner surface of an existing lighting fixture.

Abstract
An adjustable specular reflector adapted for use in existing fluorescent lighting fixtures includes a plurality of facets extending longitudinally and hingedly joined together. The reflector may be formed of a form-retaining cardboard web having a highly reflective material adhered to one side, with longitudinal score lines defining the hinge portions between adjacent facets. A malleable wire or strip is secured to each end of the web, so that the facets may be oriented in a desired focussing relationship and will remain in the field-configured orientation. A rigid channel member is secured to opposed, longitudinally extending edges of the web to maintain planarity of the reflector facets. Self-adhesive patches are secured to the non-reflector side of the web, so that the reflector may be installed in virtually any fluorescent fixture.

11. An optical reflector adapted for use in a lighting fixture, comprising;
- a web member formed of generally stiff material, one surface of said web having a specular reflective layer adhered thereto, a plurality of score lines formed in said web member to define a plurality of edge adjacent facets therein, said score lines defining hinge areas between adjacent facets to permit relative pivotal motion therebetween, said web member being configurable to a concave configuration with said specular reflective layer interior thereto, a plurality of deformable, form-retaining members secured to all of said facets and disposed to maintain said facets in selectively variable angular relationships, channel means joined to longitudinally extending edge portions of said web member and having sufficient stiffness to maintain a linear configuration thereof, and a plurality of self-adhesive patches joined to the other surface of said web member and disposed to adhere said reflector within a lighting fixture.
