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.

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： This headlamp comprises a reflector and a discharge lamp comprising an inner envelope having a longitudinal axis coinciding with the optical axis of the reflector. The inner envelope includes a bulbous portion, a front leg extending along the optical axis from the bulbous portion toward the front of the headlamp, and a back leg extending along the optical axis from the bulbous portion toward the reflector. The discharge lamp further comprises a tubular shroud comprising a first hollow portion surrounding the front leg of the inner envelope, a second hollow portion surrounding the back leg of the inner envelope, and a bulbous portion between the two hollow portions. The bulbous portion of the shroud has a central longitudinal axis, and this central axis is upwardly offset by a small distance (e.g., at least about 0.5 mm) from the longitudinal axis of the inner envelope on which the discharge is located. The presence of this offset has been found to substantially increase the ratio of the seeing light to the glare light (i.e., the SGR) in the headlamp beam as compared to that present when there is no offset between these axes.

摘要： An optical coupling assembly is useful for coupling a source of light, having high brightness and being non-coherent and focussed at a focal plane, to a plurality of optical light conductors. The coupling assembly includes an elongated light transmissive coupling member which has a central longitudinal axis and is disposed between the focal plane of the light source and leading ends of the optical light conductors. The elongated coupling member is any one of a limited number of different polygonal cross-sectional shapes. Also, the coupling member can have either a hollow tubular or a solid configuration. The hollow tubular member is coated with a highly reflective material. In one embodiment, the polygonal cross-sectional shape of the coupling member remains constant along the entire axial length of the coupling member. In another embodiment, the polygonal cross-sectional shape of the coupling member remains constant at a pair of front and rear end portions and at a middle portion disposed between them and decreases and increases along the axial length of the coupling member at front and rear transitional portions respectively disposed between the front end portion and the middle portion and between the middle portion and the rear end portion of the coupling member. The front and rear transitional portions can vary either linearly or non-linearly along their axial lengths.

摘要： A lighting system particularly suited for an automotive application in which it is desired to utilize a central light source and couple the light output therefrom to a headlamp assembly having a number of conventional components includes introducing an output end of a light guide to the reflector assembly in place of an incandescent lamp, and disposing a mirror at the output end of the light guide to reflect light onto a conventional parabolic reflector. The mirror is preferably planar and serves to direct the light from the output end of the light guide to the parabolic reflector for collimation thereby and subsequent passage through a conventional lens member.

摘要： A projection headlamp lighting system includes a light source to generate light, a light distributing arrangement to distribute the light to a preselected lighting position, and a light projecting arrangement at the lighting position to project the light in the desired pattern. The light distributing arrangement includes at least one elongated optical light conductor having respective input and output ends. The light projecting arrangement includes an optical structure in the configuration of at least one stair step attached to and protruding axially outwardly from a transverse end face on the output end of the light conductor, and a collector lens being spaced from the outer end of the light conductor. More particularly, the collector lens is spaced from an outer terminal end of the protruding step at a distance substantially equal to the focal length of the lens such that the lens is capable of gathering light projected both from the outer terminal end of the protruding step and the remainder of the output end of the light conductor and projecting the desired light pattern having a first portion focussed by the protruding step and a second portion spread by the remainder of the end face of the light conductor.

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 xenon aggravates convection which causes arc-bowing and overheating of the envelope above the arc. By operating the lamps on unidirectional current upon which a frequency-modulated high frequency ripple has been imposed, acoustic resonance is used to straighten out the arc. The use of unidirectional current permits a reduction in cost and size of the ballast control circuits operated from auto storage battery. Frequency modulation of the ripple broadens the band allowing acoustic straightening of the arc. Additional control of the arc plus reduction of cataphoresis may be achieved through a horizontal magnetic field at the arc, transverse to current flow.

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 source 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.
