Abstract: A metal halide lamp of the present invention comprises a luminous tube alone without any outer bulb, the luminous tube containing metal halides such as neodymium halides (NdX.sub.3), dysprosium halides (DyX.sub.3) and cesium halides (CsX) in a total amount by mole of 1.times.10.sup.-6 to 8.times.10.sup.-6 mol/cc and the following molar ratios: ##EQU1## as well as rare gas serving as starting auxiliary gas and mercury serving as buffer gas. This structure permits a predetermined vapor pressure of the metal halides sealed in the luminous tube to be obtained without increasing the wall load, as well as the formation of a metal halide lamp having a long life and good color characteristics.

Abstract: An optical light source device includes a source member providing the emission of electromagnetic radiation wavelengths in the optical region of the spectrum, and at least one cavity waveguide member coupled with the electromagnetic radiation source member having a predetermined lateral dimension. The cavity waveguide member and predetermined dimension restrict the emission of electromagnetic radiation in the long wavelength non-visible infra-red range. In a preferred embodiment, the optical light source is formed with an array of optical light source members and associated cavity waveguide members.

Abstract: To shorten the time between firing of a high-pressure discharge lamp and stantial light output therefrom, the discharge lamp includes a fill of xenon, at a cold fill pressure of at least 3 bar, in addition to mercury and a metal halide; the discharge vessel (2) is, at least in part, coated or doped so that invisible radiation is reflected into the lamp, or absorbed, while visible radiation is being transmitted by the discharge vessel. The shafts of the electrodes are thin, of only about 0.3 mm diameter, and the electrodes facing each other are part-spherical or rounded. The lamp is operated in combination with a lamp power supply (S) which has the characteristics of being capable of supplying between 5 to 10 times normal operating current of the lamp under starting conditions.

Abstract: A single end-sealed type metal vapor discharge lamp includes an arc tube having a bulb made up of a discharge portion defining a discharge region and a sealing portion with a shoulder portion situated adjacent to the discharge portion. A pair of electrodes have a pair of mutually opposite electrode portions on an upper end of each of the pair, the electrodes extending from the sealing portion toward the discharge region. An outer tube encloses the arc tube in which a cross-sectional configuration of the bulb has a point of inflection at a boundary between the discharge portion and the sealing portion. A straight line l connecting a center of one electrode portion to that of the other electrode potion makes an angle of 15.degree.-45.degree. with respect to a straight line L connecting the point of inflection to a midpoint of the straight line l. The shoulder portion is located at a side opposite to that, on which the straight line l exists with the straight line L as a reference.

Abstract: An HPS sodium vapor discharge lamp having a starting aid consisting essentially of a metallic band disposed circumscribing one end of the lamp discharge vessel, and means for applying a voltage to the metallic bond for inducing ionization throughout the volume of the discharge vessel to facilitate lamp starting. The metallic band may define a heat shield for inhibiting thermal radiation from one end of the discharge vessel.

Abstract: A ceramic metal halide high pressure discharge lamp has an arc gap separating the discharge electrodes which is not more than 10 mm and a wall loading which is at least 50 W cm.sup.-2. The relatively small arc gap enables a relatively low operating voltage (in the range from 80V to 130V, say) to be used.
