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： An optical coupling assembly is useful for coupling a source of light, having high brightness and focussed at a focal plane, to a plurality of optical light conductors. The coupling assembly includes a light transmissive elongated segmented rod-shaped coupling member formed of a plurality of longitudinal sections and a retainer member for holding the longitudinal sections together in an assembled relationship. The coupling member has a central longitudinal axis and at an input end is disposed at the focal plane of the light source, while at an output end is disposed against leading ends of the plurality of optical light conductors. Each longitudinal section of the coupling member has a plurality of spaced longitudinal surfaces capable of internally reflecting light traveling within the longitudinal section. The retainer member is a hollow sleeve which holds the longitudinal sections together in the nested relationship with one another such that some of the longitudinal surfaces of the longitudinal sections define an external circumferential surface of the coupling member whereas others of the longitudinal surfaces of the longitudinal sections define a plurality of internal surfaces within the coupling member which extend from the external circumferential surface to the central longitudinal axis thereof.

摘要： Miniature high pressure arc lamps containing a substantial pressure of xenon, in addition to metal halide and mercury, can provide instant light at turn-on and are suitable for automotive headlamps. The high pressure of xenon aggravates convection which causes arc bowing and overheating of the envelope above the arc. By operating the lamp at high frequency within selected bands, acoustic modes are excited in the fill which straighten the arc and make the envelope more isothermal. Frequency modulation of the input can be used to broaden the band selected for acoustic operation and relax the tolerance on arc tube and circuit parameters needed for a match. Acoustic operation may also be used to effect physical displacement of the arc for beam switching.

摘要： Flush and pump flush processes yielding light sources for incandescent and metal vapor discharge lamps are disclosed. The flush and pump flush processes also yield lamps that are particularly suitable for deposition of a reflective coating on its outer surface. For such reflective coated light sources, the associated lamp leads are encased in glass and therefore are protected against any deleterious reactions that may otherwise result from the deposition of the reflective coating process. The light sources yielded by the flush and pump flush processes of the present invention are advantageous in reducing the mounting arrangement of the lamps in which the light sources are housed.

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 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 light source includes an integral reflective coating on a portion of its envelope for reflecting light back through the source. The light from the source is directed by a reflector toward a focus thereof at which is located an input end of a light guide. The integral reflective coating allows a half ellipsoidal reflector to be used in one embodiment without depreciable loss of light. Accordingly, a pair of light sources can be arranged with a common focus to substantially double the brightness in the light guide. Alternatively, the light sources can provide a primary and redundant arrangement, or used to provide two levels of light in another arrangement. According to another embodiment, a hemispherical reflector is used to obtain unit magnification and increase the angular range through which light may enter the light guide.
