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 light coupling arrangement for use with a central lighting system having a high brightness light source disposed in a housing includes a plurality of optical fibers having input ends and output ends which are distributed to various spaced apart location in the desired manner. The input ends of the optical fibers are stripped of cladding and compressed together within a first sleeve member so that boundaries between individual optical fiber input ends are substantially eliminated thereby resulting in a color and intensity mixing at such input end which translates to a uniform color and intensity distribution to the various spaced apart locations. A rod member can be disposed in optical contact with the input ends of the optical fibers and together with the optical fibers, slip fit within an outer sleeve member that assists the first sleeve member in maintaining the compressed relation of the input ends of the optical fibers. The rod member is constructed of a light transmissive material and has a higher thermal coefficient than the optical fibers thereby protecting such input ends from damage as may be caused by the high brightness light source.

摘要： A ballast circuit and method of operating gas discharge lamps are disclosed. The ballast circuit generates a relatively low frequency regulated square-wave current which advantageously provides for operating the gas discharge lamps during their run mode. The square-wave current delivered to the electrodes of the gas discharge lamp reduces or substantially eliminates the cataphoresis effects typically created by D.C. and 60 Hz operation of the gas discharge lamp while also reducing or substantially eliminating the detrimental acoustics resonance effects typically created by operating the gas discharge lamps at relatively high frequency of excitations.

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 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.
