  • Patent number: 5479072
    Abstract: A high intensity metal halide arc discharge lamp, such as an electrodeless lamp wherein RF energy is inductively coupled to the arc discharge, contains a halide of neodymium alone or in combination with other metals such as one or more rare earth metals, Na, Cs and is essentially mercury free (i.e., <1 mg per cc of arc chamber volume).
    Type: Grant
    Filed: November 12, 1991
    Date of Patent: December 26, 1995
    Assignee: General Electric Company
    Inventors: James T. Dakin, Tommie Berry, Jr., Mark E. Duffy, Timothy D. Russell
  • Patent number: 5363015
    Abstract: A high intensity electrodeless metal halide arc discharge lamp wherein RF energy is coupled to the arc discharge, contains a halide of praseodymium alone or in combination with other metals such as one or more rare earth metals, Na and Cs and is essentially mercury free (i.e., < 1 mg per cc of arc chamber volume).

  • Patent number: 5151633
    Abstract: The fill of a self-extinguishing gas probe starter for an electrodeless high intensity discharge lamp includes a starter fill component which has a relatively low vapor pressure and is substantially inert in the starter fill at ambient temperatures, but which component vaporizes and becomes electronegative as the temperature of the lamp increases, so that the starter fill component attaches electrons of the starting discharge in the gas probe starter and thereby extinguishes the starting discharge after initiation of the arc discharge in the arc tube. As a result, the flow of currents between the gas probe starter and the arc tube, which would otherwise have a detrimental effect on the arc tube wall, is avoided.
