Abstract
A lighting device has a light source, a light pipe, two convex magnifying lenses, and an adjusting mechanism for moving the two magnifying lenses relative to the light source. The light emitted from the light source is dispersed and directed into the light pipe by a reflector. The light pipe transfers collimated light through the first and second magnifier lenses which redirects the light to produce a circular spotlight beam having uniform intensity. The size of the spotlight beam is adjusted by an adjusting mechanism.
