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 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 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： 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： 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： A method and a ballast circuit are disclosed for operating a xenon-metal halide lamp particularly suited for automotive applications with a direct curernt (DC) levels having selectable amount of ripple imposed thereon. The ripple provides for acoustically straightening the arc between the electrodes of the xenon-metal halide lamp. The DC acoustic operation has the capability of utilizing cataphoresis effect so as to provide a less distracting forward beam illumination for a vehicle.

摘要： An arc discharge headlamp system employs a single continuously operating arc discharge source to provide both high and low beam patterns. The continuously operating arc discharge increases lamp life and eliminates the problem in arc light source headlamp systems of momentary dimming when switching to high beam operation due to mercury condensing within source. The headlamp has an arc light source mounted horizontally within a reflector. Light from an arc light source is reflected by the reflector through a lens to form a low beam pattern. A mirror within the reflector is positioned to form a virtual image of the light source and which is directed towards a second lens concentric with the first lens to form a high beam pattern when combined with the low beam pattern. Switching between the high beam and low beam patterns is accomplished in a variety of ways. In the preferred embodiment, the second lens incorporates an electrically responsive light valve which either passes or blocks the virtual image of the arc light source. Alternatively, the mirror may be moved between a position that directs the virtual image through the lens to a position where the virtual image is not directed through the lens. Rather than moving the mirror, it may be blocked with a mask during low beam operation.

摘要： A liquid crystal display (LCD) is provided with a source of backlighting which augments reflected incident light to provide increased contrast. A liquid crystal cell which does not contain dye, but becomes clear when a field is applied, is sandwiched in back of a liquid crystal cell with a dye and electrically connected so that when the front liquid crystal cell is turned ON to make selected portions of it transparent, the back liquid crystal cell is OFF so that corresponding portions of it are highly reflecting. No voltage is allowed to be applied across nonselected portions of the front liquid crystal and a voltage is applied across corresponding nonselected portions of the back liquid crystal making the nonselected portions of the back liquid crystal clear, producing a display of high contrast. Sandwiched to the rear of the back liquid crystal cell is a clear plastic wedge which is edge lighted. The edge lighted wedge only appears bright in the areas where the voltage on the back liquid crystal cell is OFF or not applied thereto.
