Abstract

A laser lighting system which employs visible and reflective laser beam lighting sources to provide illumination of airport runways and taxiways, preferred approach and departure routes, seaplane base landing areas, marine waterways, as well as to assist in search and rescue operations. The laser lighting system may be a laser lighting post or a laser lighting unit for providing radiation along a surface that includes at least one laser for producing a beam of coherent visible or reflective radiation, and a glass plano-convex cylindrical lens which has an aspherical convex cylindrical surface for generating a laser line which is uniformally illuminated from end to end. The laser lighting post includes a mounting column which has an access door for providing access to a tilt switch assembly and an AC/DC power adapter unit. The mounting column is attached to a base plate by a frangible coupling. The laser lighting unit includes a case containing a flashlight light bulb, at least one battery, and laser switch means for selectively energizing the laser via the at least one battery. The laser lighting unit also includes a light bulb switch means for selectively energizing the light bulb…
