Reflector having inflection point and LED fixture including such reflector
Abstract:
A recessed light fixture includes an LED light source and a reflector extending 360 degrees around a center line of light output from the light source. A cross-sectional geometry of the reflector includes a bell-shaped curve with two radii of curvature that join together at an inflection point. One of the radii defines a top portion of the curve, which is disposed above the inflection point and reflects light in a concentrated manner to achieve desired light at higher angles. The other radii defines a bottom portion of the curve, which is disposed below the inflection point and is more diverging than the top portion.
