1. A solid state light source comprising:

  • light emitting arrays, each array comprising solid state light emitters which are mounted so that each emitter emits light away from one side of a surface and with at least one wavelength;

    at least one optical mixer, each optical mixer being positioned symmetrically with respect to at least a pair of the arrays, reflecting part of the light emitted from one of the at least a pair of symmetrically positioned arrays and transmitting part of the light emitted from another one of the at least a pair of the symmetrically positioned arrays to mix the light from the at least one pair of symmetrically positioned arrays to produce mixed light which irradiates a surface with the mixed light; and

    a housing comprising an interior curved reflective surface, the housing containing the light emitting arrays and the at least one optical mixer, and including an opening from which the mixed light is emitted and the interior curved reflective surface reflecting at least part of the light emitted from the one side of the arrays toward the surface.
