Light system for defining line of approach
First Claim
1. A system for defining a line of approach, comprising:
- light sources arranged in an array;
means coupled to said light sources for defining a primary field-of-view (FOV) from which all of said light sources are adapted to be visible to a remotely-located viewer positioned therein, wherein less than all of said light sources are adapted to be visible to the viewer when the viewer is positioned outside of said primary FOV, said means further dividing said light sources into a plurality of sections with each of said plurality of sections having a portion of said light sources associated therewith; and
a controller coupled to said light sources for controlling operation thereof in accordance with cyclical on/off sequences, each of said cyclical on/off sequences being (i) associated with a corresponding one of said plurality of sections, (ii) identical for said portion of said light sources associated with said corresponding one of said plurality of sections, and (iii) unique for each of said plurality of sections, wherein a primary waveform of light energy is defined by said cyclical on/off sequences associated with said plurality of sections and is visible to the viewer from within said primary FOV, and wherein a plurality of secondary waveforms of light energy are defined by said cyclical on/off sequences with a unique one of said plurality of said secondary waveforms being visible to the viewer based on the viewer'"'"'s position outside of said primary FOV.

Abstract
A light system for defining a line of approach uses light sources arranged in an array. The light sources are arranged such that they define a primary field-of-view (FOV) from which all of the light sources are visible. Less than all of the light sources are visible from positions outside of the primary FOV. The light sources are further divided into sections with each section having a portion of the light sources associated therewith. The light sources are controlled in accordance with cyclical on/off sequences. A primary waveform of light energy is defined by the cyclical on/off sequence visible from within the primary FOV. A plurality of secondary waveforms of light energy are defined by the cyclical on/off sequences visible from positions outside of the primary FOV.

12. A system for defining a line of approach, comprising:
-
light sources arranged in an array, each of said light sources producing light energy having the same wavelength when turned on; means coupled to said light sources for defining a primary field-of-view (FOV) from which all of said light sources are adapted to be visible to a remotely-located viewed positioned therein, wherein less than all of said light sources are adapted to be visible to the viewer when the viewer is positioned outside of said primary FOV, said means further dividing said light sources into a plurality of sections with each of said plurality of sections having a portion of said light sources associated therewith; each said portion of said light sources associated with one of said plurality of sections forming a radial slice of said array that extends out to a peripheral portion of said array; and a controller coupled to said light sources for controlling operation thereof in accordance with cyclical on/off sequences, each of said cyclical on/off sequences being (i) associated with a corresponding one of said plurality of sections, (ii) identical for said portion of said light sources associated with said corresponding one of said plurality of sections, and (iii) unique for each of said plurality of sections, wherein a primary waveform of light energy is defined by said cyclical on/off sequences associated with said plurality of sections and is visible to the viewer from within said primary FOV, and wherein a plurality of secondary waveforms of light energy are defined by said cyclical on/off sequences with a unique one of said plurality of said secondary waveforms being visible to the viewer based on the viewer'"'"'s position outside of said primary FOV, said controller excluding ones of said light sources from said cyclical on/off sequences starting at said peripheral portion of said array to reduce a cross-sectional area of said primary FOV. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
