Definitions

  • the halogen incandescent lamp according to the invention has a translucent lamp vessel sealed on one side with at least one incandescent filament arranged therein, the lamp vessel according to the invention having a cylindrical vessel section designed as a reflector.
  • the reflector in the halogen incandescent lamp according to the invention is designed as a component of the lamp vessel. This allows the conventional onelle reflector lamp can be dispensed with.
  • the halogen incandescent lamp according to the invention therefore requires fewer components, is less expensive and has smaller dimensions than the conventional reflector lamps. It can be used in downlights, for example, instead of the conventional reflector lamp. Correspondingly smaller openings can be used in the false ceiling.
  • FIG. 1 shows a side view of a first embodiment of the halogen incandescent lamp according to the invention in a schematic representation
  • Figure 2 The first embodiment in a side view rotated by 90 degrees compared to Figure 1
  • Figure 3 is a side view of a second embodiment of the halogen incandescent lamp according to the invention in a schematic representation
  • Figure 4 The second embodiment in a side view rotated by 90 degrees compared to Figure 3
  • the first exemplary embodiment of the invention shown in FIGS. 1 and 2 is a halogen incandescent lamp with an electrical power consumption of approximately 20 watts.
  • This lamp has a lamp vessel 100 made of quartz glass, which is sealed gas-tight at one end by means of a pinch seal 101.
  • the lamp vessel 100 also has a circular-cylindrical vessel section 102 and a pump stem attachment 103 arranged diametrically to the pinch seal 101.
  • An incandescent filament 110 is arranged within the lamp vessel 100, the ends of which are each connected via a power supply wire 121, 122 to a molybdenum foil 123, 124 embedded gas-tight in the pinch seal 101.
  • the molybdenum foils 123, 124 are each connected to a contact pin 125, 126 of the halogen incandescent lamp protruding from the pinch seal 101.
  • the circular cylindrical vessel section 102 is provided with a light-reflecting silver layer 104 on its outer surface.
  • the silver layer 104 extends over 50 percent of the circumference of the circular cylindrical vessel section 102 and extends to the pump stem attachment 103. In other words, the silver layer 104 covers a half-shell of the cylindrical lamp vessel portion 102 and is continued up to the pump stem attachment 103.
  • the filament 110 is axially aligned and arranged parallel offset with respect to the cylinder axis AA of the circular cylindrical vessel section 102.
  • the outer diameter of the lamp vessel 100 is 9.5 mm and its wall thickness is 1 mm.
  • the axis of the incandescent filament 110 is shifted parallel by 2 mm with respect to the cylinder axis AA in the direction of the silver layer 104.
  • the pinch seal 101 is designed as a G4 base.
  • the molybdenum foils 223, 224 are each connected to a contact pin 225, 226 of the halogen incandescent lamp protruding from the pinch seal 201.
  • the circular cylindrical vessel section 202 is provided on its outer surface with a light-reflecting silver layer 204.
  • the silver layer 204 extends over 50 percent of the circumference of the circular cylindrical vessel section 202 and extends to the pump stem attachment 203. In other words, the silver layer 204 covers a half-shell of the cylindrical lamp vessel portion 202 and is continued up to the pump stem attachment 203.
  • the incandescent filament 210 is aligned axially and offset parallel to the cylinder axis A-A of the circular cylindrical vessel section 202.
  • the outer diameter of the lamp vessel 200 is 9.5 mm and its wall thickness is 1 mm.
  • the axis of the filament 210 is shifted parallel by 2 mm with respect to the cylinder axis A-A in the direction of the silver layer 204.
  • the pinch seal 201 is designed as a G4 base.
  • the two exemplary embodiments explained above differ only in the alignment of the pinch seals 101 and 201 with respect to the light-reflecting coatings 104 and 204, respectively.
  • the power supply wires 221, 222 run in the same plane as the molybdenum foils 223, 224 and are not designed in a step-like manner as the power supply wires 121, 122 of the first exemplary embodiment.
  • the invention is not limited to the exemplary embodiments explained in more detail above.
  • the light-reflecting coating can also extend over a smaller part of the cylindrical vessel section.
  • an aluminum layer or a dichroic coating can also be used instead of a silver layer.
