Abstract

An aviation obstruction lighting system having a lamp mounted on the an aviation obstruction at an elevation sufficiently high to serve as a warning of the presence of the obstruction to pilots of approaching aircraft, a remote light source, and an optical waveguide connecting the lamp and the light source and conducting light from the light source to the lamp. The optical waveguide contains quartz glass fibers. The light source is mounted at an elevation to be manually accessible by a technician standing on, or on a platform less than two meters from, the ground. The lamp includes an optical waveguide end receiver, and a Fresnel lens surrounding a reflective element having a conical or frustoconical surface positioned to intercept and reflect light emanating from an optical waveguide, such that the reflected light is directed to an inner incident surface of the Fresnel lens.
