ABSTRACT:
An improved flashing beacon strobe in which high intensity halogen gas filled gaseous discharge tubes are used as a light source. The gaseous tubes are strobed at a desired rate by a switched high voltage high current power source. Rotating cylindrical lenses with variously colored sections are placed coaxially upon each gaseous discharge tube. In one embodiment, two gaseous discharge tubes are each equipped with a rotating cylindrical lens and a V-shaped mirror is placed between the cylindrical lenses to prevent interference and increase dispersion. Dispersion is further enhanced by using fresnel type lens material. The cylindrical lenses are rotated synchronously, a system which includes an electrical motor, rotating pods and a timing chain which maintains a constant angular relationship between the cylindrical lenses.
