1. An illumination unit, comprising:

  • a first curved reflector comprising a first reflecting surface that defines a first reflector axis; and

    a first light emitting diode (LED) positioned to emit light generally along an LED axis non-parallel to the first reflector axis, light from the first LED being reflectingly converged by the first reflecting surface towards a first target focus;

    wherein a first plane formed by the first reflector axis and the LED axis intersects the reflecting surface at an intersection region, the intersection region of the first reflecting surface extending closer towards the first focus than regions of the first reflecting surface outside the intersecting region.
