Definitions

  • This invention relates to electric lamps
  • An object of the invention is,to prevent V the gas from becoming excessively heated.
  • a further and more specific object is to provide in an electric gas lamp such a construction of the constituent parts as will permit a continuous and self-acting renewal of the heated gas in the discharge tube by e acooler gas.
  • Fig. 1 is a vertical section showing the relative positions of the discharge tube and the other container;
  • Fig. 2 is a horizontal section of the lamp taken on the line IIII of Fig. 1 illustrat- I I ing more clearly the communicating pa:-
  • the lamp may consist of the two containers 3 and 4 which for the sake of convenience are illustrated as being one within the other.
  • the outer envelope 3 may comprise a completely enclosed shell or envelope ottransparent material while the inner container, termed the discharge tube, 4 may consist of a narrow tube open at each of its ends and vertically supported in any desired manner in spaced relation from the outer lamp so that there is an intervening space 5 between these two members on all sides of the inner contalner.
  • Two electrodes -6 and 7 may be secured, by fusing or otherwise, in the openings at each end. of the inner tubes and may have connected therewith current conductors 8 and 9, respectively extending to any convenient source of electrical energy.
  • the cross-section of the electrodes may be such as to not entirely fill the inner diameter of the discharge tube and for that purpose may be provided with two flattened sides 11 so that assageways 12 may be provided leading rom the inner tube to the space 5 between ,the inner and outer containers.
  • Both envelopes may be charged with a gas adapted to become luminous upon passage of a current of electricity therethrough and it is to be observed that upon heating of the gas within the discharge tube by passage of such current and cooling of the gas in the outer container, or envelope by reason of contact with the walls thereof, a circulation of the gas through the passageways 12 at the ends of the discharge tube is eflected whereby the heated gas will be continuously renewed by the cooler gas. Thus excessive heating of the gas which is detrimental to the burning and life of the lamp, is prevented;
  • An electric gas lamp comprising two envelopes one within the other, the inner envelope comprising a discharge tube, a
  • An electric gas lamp comprising a closed envelope, a discharge tube Within said envelope and spaced therefrom, a gas within said envelope of the character adapted to become luminous upon the passage of an electrical current therethrough, and solid electrodes within said envelope and disposed adjacent the ends of said discharge tube so as to confine the discharges taking place therebetween to the discharge tube, said electrodes also being so disposed with respect to the discharge tube as to permit the heated gas to emerge from one end and the cooled gas to pass through the other end thereof.
