Abstract

An object detection system for use in airports including an airport travel surface light assembly, a rotatable sensor assembly mounted on the airport travel surface light assembly for sensing objects and an omnidirectional illuminator mounted above the rotatable sensor assembly.

Claims

1. An object detection system for use in airports comprising:

a mounting portion formed with two housing sections circumferentially joined together to form a cylindrical exterior enclosure;

an airport travel surface light assembly including;

at least first and second illuminator housings; and

at least first and second generally oppositely directed directional airport surface illuminators housed in said at least first and second illuminator housings, each of said first and second illuminator housings being housed inside of a corresponding one of said two housing sections;

a rotatable sensor assembly mounted on said airport travel surface light assembly for sensing objects; and

an omnidirectional illuminator mounted above said rotatable sensor assembly,

each of said two housing sections being formed with a rectangular aperture sealingly enclosing a corresponding one of said first and second generally oppositely directed directional airport surface illuminators.

2. An object detection system according to claim 1 and wherein said at least first and second generally oppositely directed directional airport surface illuminators comprise at least first and second generally oppositely directed LED directional illuminators.

3. An object detection system according to claim 1 and wherein said airport travel surface light assembly comprises a static airport travel surface light assembly.

4. An object detection system according to claim 1 and wherein said rotatable sensor assembly includes:
