Multicolor LED beacon

摘要

An LED beacon has a plurality of LEDs for emitting light of the same or different colors mounting along an upright member within an optical system. To provide a beacon illuminating selectively in one or more colors, the plurality of LEDs are in different groups of two or more LEDs, at least one LED in each group being of a different color. Each group of LEDs are mounted together circumferentially spaced from each other around a central axis. Each of the LEDs when activated projects light there from through the optical system provided by a collimating lens and a condensing, coupling lens. The optical system provides enhanced illumination distributed in a cylindrical beam emanating from the collimating lens. By selectively activating LEDs of the same colors or different color at different times different sequences or patterns may be generated.

主权项

1. A multi-color LED beacon comprising:
a central member; a plurality of LEDs for emitting different colors of light, in which said plurality of LEDs are in different groups of two or more LEDs, at least one LED in each group being of a different color, and said groups of LEDs are mounted circumferentially spaced from each other around a central axis provided by said central member; and an optical system within which said central member is disposed to enable each of the LEDs when activated to project light there from through the optical system out of said beacon.
