Definitions

  • the object of the invention is a combination of two luminous sources by which is obtained a light approaching very closely in its composition to that of daylight. It is known that the light of the incandescent lacks blue rays.
  • Figure 3 indicates the design of the connections.
  • the toric mer- It is known that if a low-pressure mercury vapor lamp is operated in series with an incandescent lamp, the latter regulates the'operation of mercury vapor lamp and that the combination of the two gives a white light.
  • the invention consists in the placing of mercury vapor tube in the form of a wreath or torus around an incandescent lamp and of operating the lamp and the tube in series.
  • Figure l is an eleational view showing the torus in cross section.
  • Figure 2 isa. plan view looking down on a typical lamp equipped with the torus in accordance with the invention.
  • Figure 3 is a diagrammatic view illustrating the electrical interconnection of the torus with the lamp filament.
  • Figure 1 represents succinctly the appliance used. This shows the section of the combination of the lamp and the tube. The silvered portion of the tube 2 is represented in 3.
  • This silvering has a double object, that of refiecting the radiations upwards and at the same time that of assuring the automatic lighting oi the low pressure tube, if one of the electrodes of the tube-is connected with its metallized portion.
  • FIG. 2 shows the same lamp seen in plan, the electrodes being represented in I and 5. Electrode may be fitted with a ring 6 placed around it which will constitute an auxiliary electrode.
  • Electrodes 4 and 5 may be of a known emissive type, for instance.
  • Electrode 6 may also be treated to facilitate its electronic emission at low temperatures.
  • an incandescent lamp which can normally be operated on a voltage equal to that distributed by the sector, less that of the voltage drop in the mercury tube.
  • an intermediary socket will be developed," fitted with a cap fitting any normal socket, likewise a socket bearing a supporting arm for the tube I, thus assuring the connection between lamp 2 to tube I.
  • the tube may be replaced when desired, likewise lamp 2 and the whole may be replaced by an incandescent lamp at any time. It is recommended to use torthe tube, glass giving blue fluorescence thus changing the ultra-violet radiations into blue radiations which are necessary for a good correction of the light emitted by the incandescent lamp.
  • the rare gas used to fill the tube may be either neon or argon,
  • luminescent tube carrying an electrically conductive and light reflective silvering material upon its surface, and having a pair of electrodes, the electrodes of the said luminescent tube being electrically connected in common with the illuminating filament of said incandescent lamp with one of the electrodes also being connected to the silvering material whereby the silvering material is adapted to act as an electrical conductor to facilitate the lighting of the luminescent tube when the incandescent lamp is lighted.
  • An incandescent lamp comprising a plurality of incandescent filaments,- a luminescent tube surrounding the lamp and containing a pair'of electrodes, an electrically conductiveand light in the lamp being connected to one of the electrodes oi the tube, and the other filament of the lamp being connected'to the silvering material of the tube.
  • Acombination which comprises a bulb containing a filament adapted to be heated electricaliy to incandescence, a luminescent tube of toric form surrounding the bulbous portion of the lamp, reflective material carried in the luminescent tube at a portion of the tube which is so disposed in relation to the bulb as to direct light rays forwardly from the end of the bulb.
  • the combination which comprises a bulb containing a filament adapted to be heated to incandescence, a luminescent tube surrounding the bulbous portion of the lamp, the luminescent tube comprising a pair of electrodes and comprising silvering material disposed within the tube, one of the electrodes being connected in series with the silvering material and the incandescent lamp filament, and the other of the electrodes being provided with an auxiliary starting electrode spaced slightly therefrom.
  • a lamp including a bulb containing a filament adapted to be heated to incandescence, a
  • An illuminating device comprising a combination of a bulb containing a pair of filaments adapted to be heated electrically to incandescence, a luminescent tube of toric form surroundfrom the auxiliary electrode and the other fila-' ment of the bulb, and means for impressing electrical current across the other electrode of the tube and the pair of filaments of the bulb.
