  • Electrode alignment and capsule design for single-ended low wattage metal halide lamps
    Patent number: 4636687
    Abstract: A low wattage single-ended metal halide arc discharge lamp has an isothermal arc chamber with an outer diameter (t) substantially equal to the product of a first constant and the lamp wattage plus a second constant; a fill gas and a pair of electrical conductors sealed into and passing through one end of the arc chamber to provide a pair of electrodes therein having a spacing therebetween of a distance to provide a substantially uniform current for lamps in the range of about 35 to 150 watts.
    Type: Grant
    Filed: March 27, 1984
    Date of Patent: January 13, 1987
    Assignee: GTE Products Corporation

  • High intensity discharge lamp including arc extinguishing means
    Patent number: 4390811
    Abstract: A high intensity discharge lamp includes arc extinguishing means functional when the outer envelope of the lamp fails. The extinguishing means comprises a pressure sensing diaphragm and a terminal which will melt back when an arc is drawn therebetween. The extinguishing means operates within a time interval of several milli-seconds.

  • Metal halide arc discharge lamp having shielded electrode
    Patent number: 4383197
    Abstract: A shield is disposed about the electrode of a metal halide arc discharge lamp in order to improve lamp performance. The construction and location of the shield are such as to not lower the cold-spot temperature of the arc tube.

  • High intensity discharge lamp including arc extinguishing means
    Patent number: 4362969
    Abstract: An arc extinguishing means for a high intensity discharge lamp comprises a meltable fuse wire a portion of which is surrounded by a refractory hollow sleeve of larger diameter than the fuse wire. The remaining volume of the sleeve is substantially filled with a pyrophoric material which, at an operating temperature available within the lamp, will spontaneously ignite in the presence of oxygen and generate sufficient heat to melt the fuse wire and thus open the circuit, extinguishing the lamp.

  • Metal halide arc discharge lamp having coiled coil electrodes
    Patent number: 4277714
    Abstract: An electrode for a metal halide arc discharge lamp comprises a coiled coil on a tungsten rod, the rod diameter being equal to W.sup.0.56 /0.784 mils, where W is the input power to the lamp in watts. The primary wire for the coiled coil equals D.sup.1.8 /80.8, where D is the rod diameter in mils, and is equal to half the diameter of the mandrel wire of the coiled coil.
