摘要： A luminaire with directional side-light extraction comprises a light pipe with a light-carrying core. The light pipe has light-extraction structure along a first longitudinal side of the luminaire, which is confined to a radial swath of the luminaire, along the longitudinal axis of the luminaire, of substantially less than 180°. For efficiency, the second end has light-saving structure for directing saved light from the second end towards the first end, at redirection angles other than an excluded range of redirection angles, so long as the photon content of light at so-called alpha redirection angles is at least 10 percent of the photon content of light at so-called beta redirection angles, where the excluded range of redirection angles is defined by: |βr|

摘要： An interference filter or coating is provided in a predetermined pattern on a lamp envelope. The coating is comprised of alternating layers of high and low index of refraction materials applied to a vitreous outer surface of a lamp envelope. The coating may be geometrically symmetric or asymmetric, continuous or discontinuous with respect to the coating itself or the envelope to which it has been applied. The envelope can be masked prior to deposition of the coating so that removal of the mask leaves the filter in the desired pattern. The preferred process for forming the coating includes forming a boric oxide mask on a portion of the envelope, applying the coating over the mask and removing the coating from masked areas of the envelope by dissolving the mask in an aqueous solution.

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 coupling member includes oppositely flared front and rear end portions and a middle portion disposed along the longitudinal axis, with the middle portion extending between and connected to the front and rear end portions. The coupling member can have either a solid or tubular configuration. The middle portion of the coupling member has cylindrical shape and cross-sectional size of uniform dimensions and being less than the respective cross-sectional sizes of an inlet end of the front end portion and an outlet end of the rear end portion. The front end portion of the coupling member can have either a frusto-conical or parabolic shape, whereas the rear end portion can have a frusto-conical or parabolic shape being oriented in the reverse of the frusto-conical or parabolic shape of the front end portion. The rear end portion has a greater axial length than the front end portion and the outlet end of the rear end portion is larger in size than the inlet end of the front end portion.

摘要： A light valve for regulating light through an optical fiber system includes a scattering panel interposed between first and second light guides. A reflecting surface directs the light from the output end of the first light guide toward the input end of the second light guide, thereby eliminating losses associated with known arrangements. Use of a reflecting surface advantageously provides multiple passes through the scattering panel to increase the contrast ratio between on and off states of the system, if desired.

摘要： An illumination system is disclosed which serves to reduce the divergence of a light beam exiting a small diameter optical fiber from what it was upon entering the optical fiber and is particularly suited for automotive forward lighting applications. The illumination system comprises a spherical reflector, a light source, an optical fiber, a hemispherical lens, and an air gap between the planar surface of the hemispherical lens and the output face of the optical fiber. The spherical reflector allows a light beam from the light source to be introduced into the input face of the optical fiber over a wide angle in order to minimize the diameter of the optical fiber. An air gap exists between the planar surface of the hemispherical lens and the output face of the optical fiber that together with the lens are effective in reducing the angular divergence of the beam from what it was upon entering the input face of the optical fiber. The smaller diameter fiber has the advantages of a lighter weight, less cost, greater design flexibility, and ease of manipulation compared to a thicker fiber.
摘要翻译：公开了一种照明系统，其用于减少离开小直径光纤的光束与进入光纤时的发散度，并且特别适用于汽车正向照明应用。照明系统包括球面反射器，光源，光纤，半球形透镜以及半球形透镜的平面和光纤的输出面之间的气隙。球面反射器允许来自光源的光束被广泛地引入到光纤的输入面中，以使光纤的直径最小化。半球形透镜的平坦表面与光纤的输出面之间存在气隙，与透镜一起有效地减小了光束进入光纤输入面时的角度发散。与较粗纤维相比，较小直径的纤维具有重量更轻，成本更低，设计灵活性更高，易于操作的优点。

摘要： An improved remote headlamp system includes a single light source operable in conjunction with a reflector arrangement constructed in a manner so as to generate at least two light spots from such single light source. These two light spots are picked up by the separate input ends of light transmissive elements such as optical fibers or light guides. The output ends of the light transmissive devices are directed to either side of the automobile with one side being imaged by a lens or mirror element to provide the spread portion of the standard pattern of road illumination and the other side being imaged by another lens or mirror element to provide the narrow, focused portion of the road illumination pattern. An arrangement for switching between high and low beam operation is also provided.

摘要： A light coupling arrangement for efficiently coupling a light source to a light distribution arrangement includes a solid optical coupling device constructed of a light transmissive material and configured in an essentially planar manner such that the length and width dimensions are significantly greater than the depth dimension. An aperture is formed on at least one side along the equatorial surface of the optical coupling device and allows connection to the light distribution arrangement. A bore, formed in the optical coupling device and having a flat polished surface, houses the light source in a manner such that the optical coupling device can act as a heat sink for the light source.

摘要： In this automobile lighting system there is (i) a light source that develops light when in an "on" state, (ii) an elongated light guide that has an input end for receiving light from the source and an output end to which this light is transmitted by the light guide, (iii) an indicating device at the output end for controlling the passage of light from the output end to a location exterior to the automobile, and (iv) a lens located between the indicating device and the exterior location for receiving light passing through the indicating device from the light guide output end. The indicating device comprises a shutter having an opaque portion, a light blocking position in which the opaque portion blocks the passage of light from the output end to the lens, and a non-blocking position in which light is allowed to pass through the indicating device to the lens. The indicating device also includes shutter-actuating means for shifting the shutter between its light-blocking position and its non-blocking position while the light source remains in its "on" state.

摘要： A centralized lighting system particularly suited for aerodynamically styled vehicles is disclosed. The centralized lighting system employes a pressurized lamp preferably of a metal halide having quartz light guides merged into portions of its outer surface. The portions of the metal halide lamp that are not merged with the light guides may be coated with a diffusive reflective coating that substantially prevents light from being transmitted through the coating so that all of the light generated by the metal halide lamp is directed into and transmittd by the light guides. The transmitted light of the light guide is distributed throughout vehicle to supply the forward, rearward, and interior illumination needs of the vehicle.
