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.
Claims12
A reflector for a high intensity lighting fixture comprising:
- a. a reflector frame comprising a generally bowl-shaped outer surface, an inner surface including integral mounting structure raised from and at predetermined positions on the inner surface and adapted for removably receiving 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 by complementary mounting structure to the mounting structure of the reflector frame;
- c. wherein, the inner surface having a non-symmetrical shape comprising a first portion following a first surface of revolution and a second portion following a second surface of revolution.
A reflector frame for a high intensity lighting fixture comprising:
- a. a body having inner and outer surfaces;
- b. the inner surface including integrally formed mounting structure raised from and at predetermined positions on the inner surface adapted for removable mounting of a reflecting surface;
- c. wherein the inner surface is non-symmetrical.
