1. A dental light, comprising:
at least one light emitting diode (LED) light source mounted to a substrate and configured to produce a light beam along a normal axis that is perpendicular to the substrate at an approximate center of the at least one LED light source, the light beam containing light having a plurality of angles of propagation relative to the normal axis and the plurality of angles representing an angular distribution of the light beam; and
at least one collimating lens system situated to receive the light beam and comprising an aperture situated directly downstream from the light source and configured to shape the light beam as emitted from the light source such that the angular distribution as emitted from the light source is reduced along a first axis perpendicular to the normal axis, thereby producing a shaped light beam, wherein the reduced angular distribution along the first axis corresponds with a reduction in patient eye glare at a predetermined illumination plane.
