Abstract:
1. A lighting apparatus for being positioned adjacent an area or an object to indicate the location or orientation of the area or object, comprising: a housing, including a concave channel of a fixed and predetermined curvature; a set of light emitters mounted to the concave channel for emitting light to indicate the location or orientation of the area or object and being positioned side by side with respect to one another, the light from each light emitter of the set, according to the curvature of the concave channel on which it is mounted, overlapping with the light from each immediately adjacent light emitter of the set, wherein the light emitters are staggered about a plane of reference for emitting the light outwardly from the housing at an increasing angle along the set relative to the plane of reference, such that a band of light is formed that when viewed at a distance from the housing is rotated about an axis of rotation projecting from the plane relative to the set of light emitters, the light emitters being held in an essentially fixed orientation relative to one another and the housing at all times during operation of the lighting apparatus.
