Definitions
- the invention relates to a pin base low-voltage halogen lamp with power supply conductor, which is a low-power lamp up to 50 W. as well as an incandescent lamp and the one Glass base and a metal base leading to the glass base Has power supply conductor, one end of one metal sealing pin is welded into the glass base is provided.
- the pin base low-voltage halogen lamp is an illuminant lamp and comprises a hollow vitreous body and adjoining this an essentially solid or full glass base.
- the power supply conductor is partially melted into the glass base and partially protrudes outward from the glass base.
- the power supply conductor is a solid or full structure made of metal.
- the metal of the power supply conductor an alloy of 98% by weight Ni and 2% by weight Mn.
- Nickel is an expensive metal and it is therefore desirable that the Manufacture power supply conductors from a cheaper material. however different requirements are imposed on the power supply conductor provided that meet the cheaper replacement metal sought got to. These requirements are:
- the production of the power supply conductor must not be made difficult by the use of the replacement metal.
- the replacement metal must withstand the melting temperatures of approx. 1,200 ° C that occur when the power supply conductor melts into the glass base.
- the replacement metal must have good electrical conductivity in order to ensure the current supply to the interior of the lamp.
- the replacement metal must have good thermal conductivity in order to dissipate heat from the inside of the lamp bulb to the outside.
- the replacement metal must withstand operating temperatures of 150 - 220 ° C, which occur on the part of the power supply conductor that protrudes outwards.
- the replacement metal must have good corrosion resistance in the presence of oxygen and heat.
- An object of the invention is therefore a pin base low-voltage halogen lamp to create of the type mentioned, whose Power supply conductor consists of a cheaper metal and still well meets the requirements for a power supply conductor this lamp are put.
- the pin base low-voltage halogen lamp according to the invention is solving this task, characterized in that that power supply conductor made of a stainless steel, the is austenitic and contains additions of Cr and / or Ni, or that the power supply conductor a carrier core from a non-austenitic carbon steel containing alloy additives has and the carrier core all around with a coat Nickel is provided.
- the metal is the power supply conductor much cheaper, e.g. 20% cheaper than 98% nickel Alloy or pure nickel.
- the power supply conductor shows due to the steel material regarding electrical conductivity and thermal conductivity slightly worse values than the known one Power supply conductor with the NiMn alloy; this deterioration in value is accepted because the invention Power supply conductors still meet the requirements still well fulfilled.
- the invention consists in Use of the specified special steel materials for the Power supply conductor of the pin base low-voltage halogen lamp.
- the stainless steel is known as wire in a suitable training. In in many cases it contains both Cr and Ni and in many cases it contains other additives.
- the stainless steel is in any case corrosion resistant.
- the carbon steel contains alloy additives, as is known per se is.
- the plating nickel cladding that the electrical wire this Power supply conductor takes over is e.g. pure nickel or contains up to 2% Mn and is from a few ⁇ m thick to approx. 15% of the Cross section of the power supply conductor thick.
- An embodiment of stainless steel is e.g. x5 CrNi 18/10, Werkst.Nr. 1.4301, DIN 17440; containing 0.7% C, 17 - 19% Cr, 8.5 - 10.5 Ni.
- An example of carbon steel is: D 6-2; Werkst.Nr. 1.0314, DIN 17140; containing 0.06% C, 0.06 % Si, 0.40% Mn, 0.04% Ph, 0.04% S.
- the power supply conductor according to the invention is like this designed that he with a piece of wire manufactured as drawn wire with up to 4 mm in diameter and 400 mm in length is.
- This design is for power supply conductors of the aforementioned Kind of usual.
- the power supply conductor according to the invention is also designed so that it ends up on a metal sealing pin is welded on. This design is for power supply conductors of the type mentioned in the beginning.
- the power supply conductor and the sealing pin form together the power supply, which is a manufactured product and is acted as such.
- the sealing pin is e.g. out Molybdenum, tungsten or a copper-coated FeNi wire (Dumet).
- the sealing pin is partly in the glass base of the lamp melted and partially protrudes into the vitreous.
- the lamp according to the drawing has a hollow glass body 1, which integrally merges into a solid glass base 2.
- Two power leads 3 are cast into the glass base 2, each consisting of a power supply conductor 4 and one opposite in cross section smaller sealing pin 5 exist.
- the Power supply conductor 4 and the sealing pin 5 are with the ends bumped against each other and by a weld 6 connected.
- the two sealing pins 5 carry in the glass body 1 a helix 7 made of tungsten.
- a pin base low-voltage halogen lamp is provided.
- the sealing pins 5 protrude into the glass body 1 and are directly connected to the helix 7.
- 2 is one Cold light reflector lamp provided, in which a pin base low-voltage halogen lamp is equipped with a glass reflector 8, which with a neck over putty 9 on the glass base 2.
