    摘要: A compact optical coupling member (16) is useful for coupling non-coherent light from a source of light (10) to a light distribution harness. The coupling member includes an elongated light transmissive body having a central longitudinal axis, an inlet end (14) for receiving light from the light source, and an outlet end (18) for providing light to a leading end of a light distribution harness. The elongated body has a polygonal cross-sectional shape for providing increased light mixing of the non-coherent light. The polygonal shape of the elongated body increases in size from a first cross-sectional area at the inlet end to an enlarged cross-sectional area at the outlet end for reducing, with respect to the longitudinal axis, the maximum angle of light passed through the outlet end relative to the maximum angle of light received through the inlet end. A pair of compact optical coupling members of the foregoing type may be used for coupling non-coherent light from first and second sides of the source of light to respective first and second light distnbution harnesses. A compact, folded optical system may be realized by making the polygonal shape of a an elongated body of an optical coupling member trapezoidal; and using a plano-convex lens as part of the light distribution harness. The plano-convex lens has a convex surface through which light is received from the coupling member, and a mirrored, planar surface confronting the coupling member and being for reflecting light at an angle that causes the light to substantially miss the coupler.

    摘要: A centralized lighting system (10) having a plurality of output ports includes a high brightness light source (12) disposed at the optical focal point of a parabolic reflector (14). The light source (12) and reflector (14) configuration deliver light output in an essentially parallel manner to a plurality of lens members (16,18) effective for focussing the light output into a plurality of spatially separate light spots. The spatially separate light spots are input to optical fibers (22) without experiencing packing fraction losses. The plurality of lens members (16,18) are disposed equidistantly along radii formed relative to the reflector (14) but at a spaced apart relation to the reflector (14). In this manner, the lens members (16,18) provide the spatially separate light spots which are essentially equal in terms of color and intensity to one another.

    摘要: A compact coupling arrangement between a light source (16) and a plurality of light distribution harnesses (22,24) includes a plurality of reflector members (12,14) arranged around the light source with respective focal points of the reflector members positioned substantially coincident with the light source, so as to receive light from the source and reflect the light away from the source. Further included is a plurality of light coupling members (18,20), each having an inlet and an outlet surface (18A,18B,20A,20B) for receiving light originating from the light source and transmitting light, respectively. A plurality of light distribution harnesses is provided for respectively receiving light from the light coupling members. The light coupling members each comprise a lens having a negative curvature in at least one direction generally transverse to a main light transmission axis therethrough, for receiving light at a first angular distribution and transmitting light at a reduced angular distribution. To facilitate manufacturing, at least one of the light coupling members may comprise an integral portion of one of the reflector members coinciding with the curvature of a proximate reflector member. Further, at least one of the inlet and outlet surfaces of one of the coupling members may be non-axisymmetrical about the main light transmission axis of its associated coupling member, for improving efficiency of light coupling.

    摘要: Disclosed are optical couplers (10) and optical coupling systems for coupling a source of non-coherent light to a light distribution harness, wherein the couplers are polygonal in cross section to increase light mixing. The couplers have inlet (12) and outlet (14) arms and an intermediate bend region (16A) configured to achieve compactness and minimal light loss through the bend region. In one embodiment, the bend region is an integral part of the coupler, with the inlet arm having a different cross-sectional dimension (12A) from the outlet arm (14A) in such manner that substantially all light (30) directed from the inlet portion (12) to the bend portion (16A) reaches (31,32) the outlet arm portion (14), and light rays parallel to the inlet axis are reflected in the bend portion to be directed substantially parallel to the outlet axis. In a second embodiment, the bend region comprises a prism having a pair of parallel spaced surfaces, and inlet, outlet, and third surfaces that are non-parallel to the spaced surfaces. The inlet arm projects from the inlet surface, and the outlet arm projects from the outlet surface. One of the inlet and outlet surfaces forms a first interface with a first material having an index of refraction different from that of the prism, so that light rays within the prism totally internally reflect from the first interface.

    摘要: A display system having a greyscale control arrangement for controlling light output from a plurality of optical fibers (14) includes a light source effective for supplying a high brightness light output to the input ends of the plurality of optical fibers. A plurality of piezoelectric shutter members (12) are disposed adjacent the light delivery ends of the optical fibers and are effective for controlling the delivery of light output through the optical fibers as a function (20) of the on or off condition thereof. The delivery ends of the optical fibers are disposed relative to one another so as to form a plurality of display pixels. At least two of the optical fibers are combined to form each of the pixels. The diameters of the at least two optical fibers that make up each pixel are different thereby allowing that at least four different greyscale levels can be achieved for each display pixel.

    摘要: A central lighting system for providing light to locations remote from the light source includes first and second ellipsoidally shaped reflector members (102,104) joined so as to substantially surround the light source (12). The reflector members collect the light output and focus it onto an input face of either a light guide (18) or a non-imaging optical coupling member (106,108). If the optical coupling member is utilized, an angle to area conversion occurs so as to allow light introduced at high angles to an input face of the optical coupler to exit the optical coupler at a smaller angle. The reflector members can also be configured so that respective second optical focal points can reside at the apex of the opposing reflector member thereby allowing for a coupling efficiency of approximately 70% or greater.
