Abstract
An improved lamp fixture with anti-glare function is disclosed, which comprises: a lamp; a light source; and a light-control unit, composed of a semi-Fresnel microstructure and a light-control microstructure; wherein the light source and the light-control unit are mounted on the lamp; and the semi-Fresnel microstructure is used for diffusing/collimating light of the light source while the light-control microstructure is used for controlling the resulting lighting angle. With the aforesaid lamp fixture, not only glare can be prevented, but also uniformity of the lamp fixture is improved.
