LIGHT BAR STRUCTURE HAVING LIGHT CONDUITS AND SCANNED LIGHT DISPLAY SYSTEM EMPLOYING SAME
First Claim
1. A light bar structure for use in a scanned light display, comprising:
- an elongated support arm having a plurality of light conduits formed therein, each of the light conduits including at least one input portion and a distal output end; and
a plurality of light emitters mounted on the support arm, each of the light emitters is operable to emit light and positioned adjacent the at least one input portion of a corresponding one of the light conduits so that the light emitted from each of the light emitters is optically coupled to the corresponding one of the light conduits and output from the output end thereof as diverging light.

Abstract
Apparatuses and methods for light bar structures and scanned light display systems. A light bar structure includes an elongated support arm having a plurality of light conduits. Each of the light conduits includes at least one input portion and a distal output end. A plurality of light emitters may be mounted on the support arm, each of the light emitters being positioned over an input portion of a corresponding one of the light conduits and operable to provide light thereto so that the light is optically coupled to the corresponding one of the light conduits and output from the output end thereof as diverging light. A scanned light display system includes a curved mirror positioned to receive the diverging light and configured to substantially collimate the received light. An actuator is operable to relatively move the light bar structure and the curved mirror to scan the collimated light to form an image.

32. A scanned light display system, comprising:
-
at least one light bar structure, comprising;
an elongated support arm having a plurality of light conduits formed therein, each of the light conduits including at least one input portion and a distal output end; and
a plurality of light emitters mounted on the support arm, each of the light emitters is operable to emit light and positioned adjacent the at least one input portion of a corresponding one of the light conduits so that the light emitted from each of the light emitters is optically coupled to the corresponding one of the light conduits and output from the output end thereof as diverging light;

71. A method of generating an image by scanning light on a retina of a viewer'"'"'s eye, the method comprising:
-
emitting light from each of a plurality of light conduits generally extending in a first direction, the light generated at each of the light conduits being reflected to the retina of the viewer'"'"'s eye from a reflecting surface;
moving the light generation locations in a second direction that is generally perpendicular to the first direction; and
controlling the intensity of the light from each of the light conduits.
