    Abstract: An arc lamp suitable for use as a high intensity light source in a projection system is described. A reflector is arranged to reflect the light produced by the arc into a directional light beam, secondary reflection means being arranged to direct part of the reflected beam so as to compensate for regions which are obscured by the electrodes. Means are provided within the light source to dissipate heat generated by the electrodes.

    Abstract: A light source is provided that includes a reflector for generating a substantially rectangular beam. The light source may include an arc lamp that includes a magnetic field generation means in the vicinity of the arc for reducing the arc diameter, or a secondary reflection means for avoiding part of the light that is generated from being obscured by the arc lamp electrodes.

    Abstract: The invention relates to improvements in high-pressure discharge lamps of the ceramic metal halide type of the Philips MasterColor series having a metal coil wrapped around the discharge vessel and/or at least a portion of the electrode feed through means, and having power ranges of about 150W to about 1000W, wherein the lamp has a metal coil wound around the discharge vessel and/or at least a portion of the electrode feed through means in a first position and in which metal coil the coil position of at least one coil portion, preferably multiple coil portions, and most preferably substantially all of the coil portions of the metal coil are stabilized to be substantially non-relaxed from the first position after exposure to elevated temperature conditions present during operation of the lamp. The metal coil functions as both an ignition aid and for containment in said lamp.

    Abstract: PURPOSE: A discharge lamp and a glow starter are provided to increase the service life of the discharge lamp by permitting the capsule to promote the starting of the discharge lamp and preventing consumption of the radioactive gas. CONSTITUTION: A discharge lamp(10) comprises a first electrode(11), which is the direct current negative electrode or a cathode, a second electrode(12), which is the direct current positive electrode or an anode, a filling gas(13), which is neon or argon, and lit at low pressure under the effect of an electric voltage between the two electrodes, a glass peripheral wall(14), which is covered with a fluorescent coating in the case of a fluorescent lamp, and a capsule(15), containing a radioactive gas, wherein the capsulate has a wall which is transparent to the radioactive radiation in order to facilitate starting of the discharge lamp by ionization of the filling gas, while consumption of the radioactive gas which the lamp contains is prevented.
