Highly efficient luminaire having optical transformer providing precalculated angular intensity distribution and method therefore

A light transformer comprising:

• a first end that receives light from a light source;
• a second end that outputs the received light, the second end located on an opposite end of the device from the first end;
• a first member located on a third end of the light redirecting device the first member having an outer wall comprising a total internal reflection surface;
• a second member located on a fourth end of the light redirecting device, the fourth end located on an opposite end of the redirecting device from the third end, the second member having an outer wall comprising a total internal reflection surface;
• and
• an axis located between the third end and the fourth end, the axis being perpendicular to the first end,
• wherein the first face and the second face redirects the received light in a direction of the second end.

A method for designing a reflective surface for a light transformer comprising:

• receiving maximum and minimum output angles;
• receiving a location of a portion of the light transformer with respect to a light source that provides light;
• and
• iteratively point-by-point calculating an optical transformer reflective surface by providing an associated increment for an output angle for each increment of an input angle, the associated increment for the output angle being consistent with a predetermined output intensity distribution to reflect light provided by the light source according to the received maximum and minimum output angles based on the received location of a portion of the light transformer.

An apparatus for emitting light in a predetermined pattern comprising:

• a light source that emits light;
• a light transformer having a curved conical reflective surface, the reflective surface reflecting most of the light emitted by the light source in a pattern with a precalculated angular luminous intensity distribution;
• and
• an optical window the transmits the light to the exterior of the light transformer.
