Abstract

An optical system includes conical reflectors (32) axially aligned back to back with a xenon tube (35) located in the throat (36) formed by their truncated apices, for emitting light in two opposite directions. Each reflector (32) is enclosed by a transparent cover (33) that includes a central lens (37) for evening out axial light-distribution. Alternatively, a xenon tube (15) may be located between the apices of two mutually-inverted conical reflectors (16,17) at right angles to their common axis (18) for emitting light from their external reflective surfaces throughout 360 degrees. As further alternatives, a single conical or pyramidal reflector (3,10) may be used with a LED (1) as light source, and the systems may be used for reception of light.
