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.
Claims17
An high intensity lighting fixture for increasing useable light to a target area without an increase in energy use comprising:
- a. a die-cast metal reflector frame mountable to the lamp cone and comprising a bowl-shaped outer surface, an inner surface including mounting structure adapted for a reflecting surface, and a primary opening over which a glass lens is mountable;
- b. a very high total reflectance reflecting surface mountable to the mounting structure of the reflector frame.
A reflector frame for a high intensity lighting fixture comprising:
- a. a die cast body having inner and outer surfaces;
- b. the inner surface including mounting structure adapted for removable mounting of a 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. die casting a frame having an inner generally bowl-shaped but non-symmetrical shape;
- b. mounting a high total reflectance reflecting surface to generally follow the non-symmetrical shape.
