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

A light apparatus comprising:

• a single 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, said light source located on cone axis on or close to cone vertex;
• and
• an optical window that transmits the light to the exterior of the light transformer, said transmitted light having a pattern determined by a precalculated angular luminous intensity distribution of high efficiency, wherein the optical window forms a truncated cone with the light transformer.

A light transformer for highly efficient directing and redistributing light from a light source in a predetermined pattern with low divergence or substantially parallel with an axis of light direction comprising:

• a first end that receives light from the 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 device between the first end and the second end, wherein the first member has an outer wall comprising a total internal reflection surface that redirects and redistributes the received light in a direction of the second end;
• a first planar optical window located at an end of the first member, the first planar optical window being substantially perpendicular to the axis of light direction;
• a second member located on a fourth end of device, the fourth end located on an opposite end of the device from the third end, between the first end and the second end, the second member having an outer wall comprising a total internal reflection surface which redirects and redistributes the received light in a direction of the second end;
• a second planar optical window located at an end of the second member, the second planar optical window being substantially perpendicular to the axis of light direction, the second planar optical window further being symmetrical across the axis of light direction with the first planar optical window;
• and
• an aspheric lens located between the first and the second members, the aspheric lens having an input side on the first end of device and an output side on the second end of device, the output side of aspheric lens located between the first and the second planar optical windows.
