LED beacons

Abstract

An LED beacon has a base and four vanes upon the base extending radially outward from a central axis which lies perpendicular to an upper surface of the base. The vanes are formed using two circuit boards that intersect each other at a right angle, in which each of the circuit boards provides two of the vanes extending outwards in opposite directions from the central axis. Each vane has two opposing surfaces, and upon each such surface are mounted, in proximity to the central axis, one or more LEDs producing same color or different colors of light. A controller enables the LEDs to output light in multiple modes of solid on, flashing and/or rotating patterns along the 360 degree extent of a lens upon the base, and substantially along the height of the lens, for projection preferably as collimated light. LED beacons thus having mono-color and multicolor operation are provided.
