Abstract
An method and apparatus that generates light at various up-angles. A planar surface having a plurality of LEDs equally spaced in a circular arc directs light at a conical reflector, which redirects the generated light in a 360-degree arc of light (i.e., light beam) that is then concentrated by a magnifying lens. The light beam has a small vertical angle of divergence and appears to originate from a point light source in the center of the conical reflector. A base assembly has mounting positions to which the planar surface, conical reflector and magnifying lens are secured and maintains the lantern in an up-right position. The base assembly includes a plurality of mounting positions for securing the planar surface at various predetermined distances from the conical reflector, thereby directing the generated light beam at a corresponding predetermined up-angle. In the preferred embodiment, light produced by four LEDs with 30-degree spreads is redirected by the 45-degree conical reflector to create a 360-degree arc of light outward from the conical reflector.
