Definitions

  • Lamp constructions are known, according to which there are provided in an outer transparent or translucent envelope two or more different lighting bodies, some of which consist of vapour lighting tubes and the others of glowing filaments.
  • the glowing filaments are arranged either below or alongside the vapour lighting tubes.
  • the lighting bodies are connected in series.
  • a two pole connecting cap which means that both'of the lighting bodies are always connected or disconnected to or from the source of current at the same time.
  • the object of the present invention is an electric lamp which is similar to the known lamps above referred to, but which is designed with the production of a mixed light especially in view.
  • a further object of the invention is to provide a lamp in which each of the two lighting bodies form a part of two independent circuits, so that by switching on the lamp, the glowing filament will burn right from the beginning at full rate, Without being influenced by the lighting tube which will take some time until it has reached its steady stage of functioning.
  • the lighting. bodies. each of which have one pole connected separately. to the lamp cap may be connected and energized in various combinations.
  • a plurality of different lighting possibilities can be obtained with a single lamp according to my invention.
  • the lamp according to the invention comprises a closed transparent or translucent envelope provided with connecting cap and enclosing at least two lighting bodies, one of which is a lighting tube and the other a glowing filament, and is characterized by the lighting bodies being connected at one end to a common terminal and at their other ends to separate terminal connecting means, the glowing filament being arranged in such spaced relatino with regard to the lighting tube itself arranged axially in said envelope, that good mixing of the light sent .out by both of the lighting bodies is secured.
  • the lighting bodies are connected at one end to a common contact terminal of the lamp cap and at the other end at two further separate contact terminals of said cap.
  • This particular embodiment has the advantage I ductors S1 and S2.
  • a choking coil or the like situated at any suitable place outside of the lamp may be connected in series with the lighting tube. Besides, either one of the lighting bodies or both of them can be burned.
  • Anotheradvantage of the lamp according to the invention is that a good mixed light is obtained, in as much as mixing of the light from the lighting bodies is already obtained at the source.
  • Figure 1 shows a part section through the first embodiment of the electric lamp according to the invention
  • Figures 2-4 show diagrammatically three further embodiments of the lamp according to the invention.
  • the closed glass envelope A such as of the kind used for incandescent lamps and provided with a con.- necting cap 0
  • two diflerent lighting bodies of which one is a metallic vapour tube as for instance a mercury vapour or a sodium vapour tube, and the other a glow filament R suitably arranged outside this tube R
  • the glow filament R lies within a space bounded by two parallel planes which pass through the end points of the length of the light tube R and are transverse to the axis of the latter. Good mixing of the light from the two bodies is thereby already obtained at the source.
  • the two lighting bodies R and R have one pole of each connected to one terminal of the cap 0 and the other pole of each carried separately to the cap 0 of the lamp.
  • r and r are the connecting leads to R and R and r is the common return lead.
  • E and E are the main electrodes and R is a resistance connected in series with an igniting electrode of the tube R
  • con- Lead 1 is electrically continued in desired manner. to conductor S2, while leads r and r are electrically continued, with the interposition of conventional control means such as knife switches .91 and s2, respectively, to conductor S1.
  • a stabilizing impedance in the form of a conventional choke coil D may be included in the connection 1' between the supply source and the vapor tube.
  • glow filament R and the electrode E or the tube R provided with a heating coil are in series and are connected directly to the supply mains, the glow filament R in the first place serving as an illuminant, and in the second place also as resistance.
  • E is an electrode directly heated from the mains and E an electrode indirectly heated from the mains.
  • r is the connecting lead of the electrode E in series with the glow filament R and r is that of the electrode E r is the common return lead.
  • Supply conductors S1 and S2 are provided; and supply conductors r and r are shown as connected, through conventional control means such as knife switches 86 and 87, respectively, to conductor S1.
  • Lead r is connected to conductor S2.
  • a stabilizing impedance in the form of a conventional choke coil D may be included in the connection 1 between the supply source and the vapor tube.
  • the electrode E of the tube R is, in contradistinction to Figure 3, arranged so that itv has its higher potential end towards the electrode E so that the arc is formed with the full operating voltage of the tube R and is in parallel with the heating coil E
  • the lighting tube as such and the glow filament are also connected at one end to a common terminal and attheir other ends to separate terminals.
  • the flow filament connected in the above said manner assumes simultaneously the function of a series resistance, the application of this mode of connection to vapour lighting tubes with directly heated electrodes, that is with electrodes which are heated by the lighting arc itself, having the advantage that the ignition electrode can be dispensed with, whilst in lightly vapour tubes velope, a connecting cap thereon, two separately operated and independent lighting bodies mounted within said envelope, one said body comprising a centrally disposed vapor lighting tube, the other body comprising a glow filament surrounding the discharge path of said lighting tube, said glow filament being electrically in parallel connection with said vapor tube, and capable of operating at substantially the full operating voltage of the supply source to which the lamp is connected, a common terminal for one end of each said lighting body, and separate terminal connecting means for the free ends of said lighting bodies,

  • two independent light sources in said envelope for producing light emission of desired intensity and desired combinations of intimately and homogeneously mixed light radiation
  • one said source comprising a gaseous discharge tube, electrodes at each'end of said tube, one of which electrodes is of the incandescent type
  • the second source comprising an incandescible filament disposed coaxially and closely about the discharge path of said tube, the said filament being electrically in series with the electrode of the incandescent type, and in parallel with the discharge with indirectly heated electrodes the usual leal-rage transformer becomes unnecessary.
  • the electrode is fed directly from the supply mains and independently from the discharging operation.
  • An electric lamp for the production of an intimate and homogeneous blending of mixed light comprising a transparent or translucent en.
  • an electric lamp for the production of blended light of any desired composition comprising a vitreous envelope, through which the light can pass, a base for said envelope, a metallic vapor discharge tube disposed lengthwise in said envelope, an incandescible filament taking substantially the full supply potential disposed in said envelope, closely adjacent to and coaxial with said tube, said tube and said filament being disposed electrically in parallel, the filament and tube being in independent circuits,
