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

摘要： A lamp assembly includes improved thermal management properties provided by a thermal shield received about the neck region of a reflector. This reduces the temperature in the seal region of the light source. Additionally, the thermal shield can be incorporated into a modular housing to provide a contained lamp assembly. The module includes cooling fins that effectively reduce the temperature of the module without adversely effecting the light output. Alternatively, the housing is operatively connected to an external, secondary heat sink.

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： A high brightness discharge light source includes an arctube having an arc chamber formed therein and in which is disposed a fill of gas energizable to a discharge condition. At least two electrodes extend into the arc chamber and are separated by an arc gap of between 2 and 3.5 mm. The dose of mercury disposed in the arc chamber and various arc tube dimensions are selected so as to achieve a balance between three constraints including operating voltage thereby defining lamp efficacy, convective stability and structural integrity of the discharge lamp. A balance between arc gap, arc chamber diameter, wall thickness and the mercury density of the lamp yield a discharge lamp which achieves a light output on the order of 50,000 lumens per square centimeter.

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.
