摘要： A beam spreading device for use with a centralized lighting system and which can be applied to emergency vehicle lighting applications achieves a beam pattern light output which is essentially continuous over an output range of plus and minus 45 degrees from a center point. The beam pattern light output also has a predefined height associated therewith. The beam spreading device is constructed so as to have a curved surface which mixes the light travelling therethrough so as to achieve the continuous light output. Side wall surfaces of the beam spreading device provide for total internal reflectance properties of the beam spreading device. In one embodiment, a color wheel can be interposed between the output of optical fibers which transmit the light from the centralized light source to the necessary remote location, and the beam spreading device. The color wheel provides the ability to generate different color light outputs from a single light source. In another embodiment, the side wall portions are curved to enable significant packaging depth advantages.

摘要： A lighting system and method for broadcasting colored lights as emergency warning signals from a light source. A centralized continuous light source is coupled via a fiber optic transmission medium to an external display location such as a lens or the like located on a vehicle. The color and the relative intensity of each color is periodically modulated to alternate between at least two states such that the contrast between these alternating states is perceived by observers to be a flashing source of light with no off-time. The frequency and the duty cycle of the repetition rate of alternating between the states may be further controlled to better draw attention to the light source.

摘要： A display system having a greyscale control arrangement for controlling light output from a plurality of optical fibers 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 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 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 a light source includes first and second ellipsoidally shaped reflectors joined together to surround the light source. The first and second reflectors direct the light from the light source to light guides which are fixed at a position outside of the joined together reflectors. The ellipsoidally shaped reflectors each have an opening or window along an optical axis through which the reflected light passes to the light guides. The configuration of the reflectors allows the light the be received by the light guides outside of the reflectors. A base secures the light source in a fixed position with respect to the reflectors and allows the light source and reflector module to be removed and replaced as a single unit without repositioning the light guides.

摘要： An optical couplers and optical coupling system 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, and the coupler has inlet and outlet arms, and an intermediate bend region 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 from the outlet art in such manner that substantially all light directed from the inlet portion to the bend portion reaches the outlet arm portion, 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 compact optical coupling member is useful for coupling non-coherent light from a source of light to a light distribution harness. The coupling member includes an elongated light transmissive body having a central longitudinal axis, an inlet end for receiving light from the light source, and an outlet end 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 distribution 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 light source and optical delivery arrangement for use with a projection lighting system as may be used in the stage and studio fields, includes a high brightness light source which achieves a light output in excess of 4000 lumens at a power rating of approximately 60 watts and wherein such efficiency is achieved in conjunction with a rated life of greater than about 4000 hours for such light source. The light source is disposed at the first optical focal point of an ellipsoidally shaped reflector with an input end of an optical coupler disposed at the second optical focal point of the reflector in order to receive the light output from the light source. The optical coupler member has a cross-sectional surface area which is polygonal in shaped and is effective so as to provide a light output therefrom which is essentially uniform in terms of color and intensity. A prismatic member is disposed on the optical coupler member for re-directing the light output into a lens member. The lens member is effective for shaping the light output into the desired beam pattern.

摘要： A centralized lighting system is provided having a high intensity light source which is disposed at approximately the first optical focal point of an ellipsoidally shaped reflector member. A mirror member, disposed in advance of a second optical focal point associated with the reflector member, receives light output from the light source and is constructed so as to divide the light output into at least first and second beam portions. The mirror member is further effective so as to separate the first and second beam portions by at least 90 degrees relative to one another. Corresponding at least first and second optical transmission members are receptive of the first and second beam portions and are effective for communicating the light output to locations remote from the light source. In one embodiment, the mirror member is V-shaped and is constructed of first and second mirror segments joined together so as to form an angle of less than about 85 degrees therebetween. The mirror member is effective for dividing the beam portions so that such beam portions are substantially equivalent to one another in terms of intensity, shape and color. The V-shaped mirror member is further effective for separating the first and second beam portions by approximately 180 degrees relative to one another.

摘要： A retrofit optical assembly is provided for automotive headlamps that includes a multi-planar mirror that cooperates with a tapered end of a light guide to reduce glare. In an asymmetric parabolic reflective surface arrangement, the multi-planar mirror is offset from the longitudinal axis of the light guide to equalize the magnification and image size. This also has the beneficial effect of reducing the amount of light loss outside of the parabola.

摘要： A compact coupling arrangement between a light source and a plurality of light distribution harnesses includes a plurality of reflector members 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, each having an inlet and an outlet surface 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.
