Color temperature tunable led-based lamp module

A method for mixing and folding light for illuminating a target subject from a plurality of light sources, comprising the steps of:

• generating a first light beam from a first light source and a second light beam from a second light source;
• mixing said first light beam and said second light beam in a light mixing rod to produce a mixed light beam;
• reflecting said mixed light beam by a first reflector toward a second reflector as a first reflected light beam;
• and
• reflecting said first reflected light beam by said second reflector as a second reflected light beam.

An array lamp for illuminating a target subject, comprising:

• a plurality of lamp modules, each lamp module further comprising:
• a light mixing rod comprising an ingress end and an egress end;
• a lamp comprising a plurality of LEDs in optical communication with said light mixing rod ingress end;
• a first reflector in optical communication with said light mixing rod egress end;
• and
• a second reflector in optical communication with said first reflector,
• wherein said light mixing rod egress end is disposed substantially between said first reflector and said second reflector.
