1. A light source comprising:

  • a light emitting semiconductor device; and

    a support substrate having a generally planar reflective surface that supports the semiconductor device, the light emitting semiconductor device heat sinking via the support substrate; and

    a curved reflector having a concave reflective surface, the light emitting semiconductor device arranged between the generally planar reflective surface and the concave reflective surface, the support substrate and the curved reflector together defining a light aperture through which light produced by the light emitting semiconductor device passes.
