Definitions

  • the invention relates to a lamp, which consists of a halogen lamp of low power and a base part, for bayonet-like installation in a display device.
  • the halogen incandescent lamp has power leads led out at the end of its glass base and snap-in projections formed on the glass base.
  • the base part has a recess for receiving the base contacts and the glass pinch base of the lamp.
  • the object of the invention is to create a lamp with a base part which accommodates the lamp in a height-fixed manner without additional holding parts.
  • the lamp shown in the drawings consists of a halogen light bulb 1 of low power and a base part 2.
  • the lamp 1 has two power leads 3 led out at the end of its glass base.
  • Locking projections 5 are formed on the opposite broad sides of the glass pinch foot 4.
  • the base part 2 is preferably made of a high temperature resistant plastic, for example polyamide with 25% glass fiber.
  • this base part 2 there is a recess 6 for receiving the base contacts 7 and the glass pinch base 4 of the lamp 1.
  • Intermediate walls 8 are integrally formed in the recess 6, which resiliently abut on the broad sides of the glass pinch foot 4 when the lamp 1 is inserted.
  • catches 9 in this exemplary embodiment in the form of a web arranged perpendicularly to the longitudinal axis A of the lamp, are provided on the upper ends of the intermediate walls 8 on these intermediate walls 8, which are behind the latching projections 5 the lamp 1 intervene.
  • Grooves 10 are provided on both sides of the intermediate walls 8 in order to expand the narrow sides of the recess 6, parallel to the lamp longitudinal axis A, into which the base contacts 7 are inserted.
  • the contacts 7 are anchored in the base part 2 by means of the tongue 11.
  • the upper end of the socket contacts 7 merges into two tabs which, for example, on a printed circuit board (not shown) rest on both sides when the lamp is inserted. At the same time, the tabs are provided for the bayonet-type anchoring of the lamp in the circuit board or display device.
  • the anti-rotation devices 12 on the flange 13 encircling the base part 2 support the bayonet-like connection.
