摘要： A lamp is provided having an arctube having a light-transmitting envelope. The arctube is surrounded by a gaseous medium confined by a containment envelope such as a hermetic shroud. The gaseous medium is preferably He or H2 or Ne or another gas whose thermal conductivity is greater than that of N2 at 800° C., or a mixture thereof, to help cool the arctube. The inside and/or outside of the shroud may be coated with a diffusion barrier. To help cool the hot spot of the arctube the gap between the shroud and the envelope can be made small, the portion of the shroud wall near the arc can be thickened, the arctube can be offset above the longitudinal axis of the shroud, and the return lead of the arctube can be located between the shroud and the arctube.

摘要： A xenon metal halide lamp having an improved electrode structure that is particularly suited for automotive applications is disclosed. The electrode is comprises of a tip portion that is located at one end of a shank with the shank having a filament coiled therearound. The tip and shank portions are designed to allow for high initial current during starting and low current during operation. The coil filament is situated in opposite neck portions of an envelope forming the light source so as to; (1) cause the electrodes to be axially aligned within the light source; (2) keep the shank of the electrode from intimate contact with the envelope thereby preventing the condensation of the mercury and allowing for substantial vaporization of the metal halide ingredients at the neck portion; and (3) prevent the thermal expansion of the electrode from cracking the envelope.

摘要： A high brightness discharge light source having improved thermal balance characteristics includes a lamp envelope having an arc chamber formed therein and a pair of electrodes extending into opposite ends of the arc chamber so as to be displaced from one another by a distance of no greater than 4 mm. A fill disposed within the arc chamber is excited to a discharge state upon the introduction of an excitation energy coupled through the pair of electrodes. The light source is operated vertically so that one of the electrodes is disposed at the top region and the other electrode is disposed at the bottom region of the arc chamber. The arc chamber is formed having a diameter dimension which is just larger than the spacing between the electrodes, and a height dimension which is approximately twice the diameter dimension. The diameter dimension is substantially uniform along the length of the arc chamber. The uniform diameter characteristic is effective so that the thermal operating properties associated with the discharge state are substantially equally distributed from the top to the bottom regions of the arc chamber thereby resulting in extending the life of this light source to approximately 6000 hours.

摘要： A linear double ended lamp can be modified into a number of non-linear arrangements by heating selected regions of the lamp ends to the softening temperature and bending the lamp ends to a desired angular configuration. Preferably, the lamp ends are bent across the sealing foil that is hermetically sealed to the lamp envelope. One or both ends of the lamp can be bent as desired to define a variety of configurations. According to the method of forming the bent double ended lamp, selected regions of the lamp are raised above the softening temperature while the remainder of the lamp is maintained at a lower temperature. Preferably, the lamp ends are bent along an axis offset and parallel to the longitudinal axis of the lamp to prevent accumulation of material.

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.
