Abstract: A discharge lamp in which ultraviolet radiation of short wavelengths can be advantageously cut and in which the amount of emitted light (i-line) of 365 nm wavelength can be increased is achieved according to the invention by providing a quartz glass arc tube that is coated with a plurality of coating layers which include a layer which has Ta.sub.2 O.sub.5 as the main component, and at least one additional coating layer which has a refraction coefficient which differs from the refraction coefficient of the coating layer having the Ta.sub.2 O.sub.5 main component. These layers act to prevent the reflection of light with a wavelength of 365 nm which is incident on the coatings on the arc tube and to cut at least 50% of the ultraviolet radiation having wavelengths of 230 nm or less. According to the invention, the coating layers can be provided on the outer side of the arc tube, on the inner side of the arc tube, or on both on the inner and outer sides of the arc tube.

Abstract: An arc lamp embodiment of the present invention comprises a triplet set of annular reflectors that gather light from an arc created between an anode and a cathode into essentially parallel beams that exit along the longitudinal axis of the generally cylindrical lamp through a sapphire window. A first of the three reflectors has a concave parabolic shape that reflects light out along the lamp axis in one bounce. A second of the three reflectors has a concave elliptical shape with a rear projecting focus and is back to back with the first reflector such that the open bowls of the reflectors face in opposite directions along the axis of the lamp. A third of the three reflectors has a convex parabolic shape that receives light bounced from the second reflector and gives it a second bounce out through an opening in the first reflector and then through the window, parallel to the lamp axis. The third reflector is concentric with the first and second reflectors and its body bows into the bowl of the second reflector.

Abstract: A lamp containing a fill of xenon, mercury and metal halide is disclosed which serves as a light source for lighting applications and is particularly suitable for automotive forward lighting applications. The xenon ingredient operates to provide for instant light necessary for automotive applications, whereas, the mercury and metal halide ingredients operate to provide for a long life, high efficiency lamp relative to either a xenon or tungsten lamp. The dimensions of the xenon-metal halide lamp of the present invention are approximately three-fifths (3/5) of those of a typical tungsten lamp utilized for automotive forward lighting applications. The reduced dimensions of the xenon-metal halide lamp allows for correspondingly reduced dimensions of a related reflector for such a xenon-metal halide lamp which accommodates the needs of aerodynamically styled automobiles.

Abstract: A xenon short arc discharge lamp has a lamp bulb (1) of quartz glass, into which two rod-shaped electrodes (4, 5) protrude, the spacing of which is shorter than the diameter of the shaft (8) of the cathode (5); the cathode (5) is provided with a conical, obtuse tip (9). By doping with a metal halide, such as thallium iodide, the spectral radiant intensity per unit area in the plasma zone immediately in front of the cathode (5) is increased substantially compared with an undoped xenon short arc discharge lamp, and as a result of a flow-controlled tungsten-halogen cycle process, a stabilized cathode spot operation is attained, and the inner wall of the lamp bulb (1) remains free of tungsten deposits.
