Abstract
A compact work light that generates a light beam having high brightness and high illumination uniformity is disclosed. The work light includes a housing that houses a light source, a light homogenizer and an imaging lens in an operational relationship. The housing is attached to an adjustable mount, which can be attached to a fixed region such as wall, or to a movable support member such as a lamp base. The light source generates light that is uniformized by the light homogenizer. The homogenized light is then imaged by the imaging lens as a highly uniform, bright beam spot having a sharp boundary. The beam spot is formed at a selectable distance from the work light by varying the imaging lens and/or the adjustable mount. The work light is useful for a variety of industrial, professional and personal applications, including but not limited to a reading light, a dentist light, a head lamp, a head light and an optical projector.
