  • thermoplastic polyphenylene sulfide PPS
  • Utility Model G 82 28 218.8 shows a halogen incandescent lamp with a lamp base, which is composed of a metallic fixing sleeve and a plastic component.
  • a thermoplastic material from the group of polyamides is proposed as the material for the plastic component.
  • the object of the present invention is to provide an incandescent lamp in the lower and middle power segment, whose manufacturing costs are reduced. This object is achieved by an incandescent lamp according to claim 1.
  • the low or medium power incandescent lamp according to the invention has a lamp vessel and a lamp base, the lamp cap being made of polyamide (PA) or polyethylene terephthalate (PET) or polybutylene terephthalate (PBT).
  • the lamp base has a filler of glass fibers and / or glass beads and / or mineral substances. As a result, the manufacturing cost of the lamp cap and thus the bulb are reduced.
  • the filler accounts for 20-65% of the lamp base volume.
  • a sealing ring between the lamp vessel and the lamp base is arranged. This prevents ingress of moisture between the lamp vessel and the lamp cap.
  • the sealing ring is made of an elastomer, preferably of ethylene
  • EPDM Propylene-diene rubber
  • NBR nitrile rubber
  • a potting compound which preferably consists of epoxy resin. This prevents ingress of moisture between the lamp cap and the contact lugs.
  • the tabs extend approximately at right angles to a lamp longitudinal axis.
  • the power consumption of the incandescent lamp according to the invention is less than 40 watts.
  • a comparatively low heating of the incandescent lamp is given, resulting in a corresponding resistance of the lamp cap, the sealing ring and the potting compound.

Abstract

L'invention concerne une ampoule à faible ou moyenne puissance qui présente une enveloppe et un socle, ce dernier étant fabriqué dans du polyamide (PA) ou du poly(éthylène téréphtalate) (PET), ou du poly(butylène téréphtalate) (PBT). Le socle de l'ampoule comprend une charge en fibres de verre et/ou en billes de verre et/ou en matériaux minéraux. Les coûts de fabrication du socle de l'ampoule et de l'ampoule elle-même sont ainsi réduits.
