    摘要： A low-wattage metal-halide discharge lamp has a quartz tube of the double-ended type that forms a bulb or envelope, a pair of electrodes, e.g., an anode and a cathode, which penetrate into an arc chamber inside the envelope, and a suitable amount of mercury plus one or more metal halide salts. The electrodes are each formed of a refractory metal, i.e., tungsten wire, extending through the respective necks into the arc chamber. Heat dissipation through the neck is controlled by constructing the quartz shanks to that they have shank segments of a desired surface area that extend from the necks a distance equal to the length of the arc chamber. A shank segment loading factor defined as the rated power divided by the shank segment surface areas, and should be in a target range of 12 to 36 w cm.sup.-2. Lamps of this design achieve high efficacy at relatively low power, i.e., below 30 watts.

    摘要： A low-wattage metal-halide discharge lamp has a tube of the double ended type that forms a bulb or envelope, a pair of electrodes, e.g., an anode and a cathode, which penetrate into an arc chamber inside the envelope, and a suitable amount of mercury plus one or more metal halide salts. The electrodes are each formed of a refractory metal, i.e., tungsten wire, extending through the respective necks into the arc chamber. Heat transfer along the tube wall and through the necks is controlled by designing the bulb wall so that the cross sectional areas at the necks and at quarter-chamber planes halfway between the necks and a midplane have a respective quarter chamber loading factor and a neck loading factor each within a desired range. Lamps of this design achieve high efficacy at relatively low power, i.e., below 40 watts.

    摘要： A diagnostic instrument includes an illumination system for providing illuminating light and an imaging system for directing the illuminating light to a target and for transmitting light reflected from the target to a viewing location. The imaging system includes an electrically controllable variable focus liquid lens assembly for focusing the light reflected from the target at the viewing location. The liquid lens assembly includes at least one liquid lens including a housing filled with a first liquid, and a drop of a second liquid being in contact with the first liquid in a predetermined form. The lens further includes a first electrode insulated from the second liquid and a second electrode in electrical contact with the first liquid. A variable voltage control selectively applies a voltage to the first and second electrodes to vary the focus of the lens. An electronic imager is provided to capture the reflected target image.

    摘要： A metal halide arc discharge lamp is disclosed having a power input rating of not more than 35 watts. The lamp includes an envelope of light transmissive material, such as fused quartz, including a bulb portion, a pair of transitional neck portions extending from the bulb portion, and a pair of stem portions extending from the transitional neck portions respectively. The bulb portion of the envelope defines an arc chamber therein and has an external surface area of such value as to produce a wall loading not exceeding 35 watts/cm.sup.2. The arc chamber contains a fill of mercury, inert gas and metal halide. The mercury and the metal halide are adapted to substantially vaporize during operation of the lamp. A pair of electrodes extend into the arc chamber from the pair of neck portions respectively. Each electrode has an electrode tip spaced apart from one another by a distance A within the arc chamber. The neck portions of the envelope each have a wall surrounding a segment of one of the electrodes. The walls of the neck portions each have a stretched section with a minimum wall thickness not exceeding about 1.5 mm. A pair of inlead assemblies are electrically coupled to the pair of electrodes respectively. The inlead assemblies pass from the electrodes through a hermetically sealed section in the stem portions of the envelope to the exterior of the lamp.
