Abstract
An apparatus and method for a high intensity lighting fixture. In one aspect, instead of a spun aluminum bowl-shaped reflector, a die cast metal reflector frame, somewhat simulating a bowl shape, includes an inner surface with mounting structure. A high reflectance sheet or plurality of high reflectance inserts are placed onto the mounting structure to create a reflecting surface. This allows high customability of the reflecting surface and minimizes light loss.
Claims26
A reflector for a wide-area high intensity lighting fixture comprising:
- a. a cast frame comprising an inner surface revolved around an axis and a primary opening along the axis over which a glass lens is mountable;
- b. a separate, very high total reflectance reflecting surface mounted to the inner surface of the reflector frame, the reflecting surface comprising a plurality of pieces.
A reflector frame for a high intensity lighting fixture comprising:
- a. a cast metal body having inner and outer surfaces;
- b. the inner surface including cast mounting structure adapted for removable mounting of a multi-piece reflecting surface.
A method of capturing and controlling light from a high intensity light source for a controlled concentrated beam for a relatively distant target area comprising:
- a. casting a frame having an inner generally bowl but nonsymmetrical shape;
- b. mounting a multi-piece high total reflectance reflecting surface to generally follow the non-symmetrical shape.
