Abstract
A medical headlamp that includes a tubular housing an electrical network electrically connected to an electrical conductor, a bare LED assembly electrically connected to the electrical network, an annular light block defining an aperture placed in front of the LED, and an optical assembly including at least a light focusing lens placed in front of the annular light block. A central beam of light from the LED passes through the aperture, and peripheral light from the LED is blocked by the light block such that the central light beam is focused by the optical assembly to create a beam of light having sharp edges.
