Definitions

  • the invention relates to an electric lamp with no cement, consisting of a lamp bulb with current leads led out at the pinch and a base part.
  • the lamp bulb and base part are connected to one another via a holding element, which consists of at least one sleeve made up of two shell halves, which comprises the lamp pinch.
  • the holding element consists of a sleeve consisting of two shell halves, each shell half being fastened to a fixing ring by riveting or welding, etc.
  • This fixed ring is connected to a metal base sleeve by flanging the edge.
  • the production of the holding element is quite complex due to these many operations.
  • the invention has for its object to provide a lamp without cement, in which the lamp bulb and base part, which can also be made of plastic, are attached by a simpler design of the holding element.
  • the webs are advantageously formed on the end of the sleeve facing the lamp bulb or the corresponding ends of the shell halves and then bent back, so that the path to transfer the heat generated on the lamp is as long as possible and guarantees a high heat loss.
  • at least one recess is provided in the webs, through which the heat conduction to the base is reduced.
  • the poor thermal conductivity is further supported by the selection of the material for the holding element, for example a stainless steel. Such measures are particularly advantageous when using plastic bases which do not withstand excessively high temperatures.
  • the shell halves have means on both sides which are provided for connecting the two parts to the sleeve comprising the lamp pinch. Both shell halves are constructed identically, so that a tab on one side is surrounded by angled tongues on the other side. Additional, partially punched tongues on the shell halves interact with depressions in the lamp pinch.
  • the free ends of the webs which are adapted to the curvature of the base sleeve opening, can be welded to a base sleeve made of metal.
  • a base sleeve made of metal.
  • they For attachment to a plastic base part, they have a bead which is provided with openings. After connecting the holding element and the plastic base part using high-frequency heating, the are Breakthroughs penetrated by base material.
  • kinks for stiffening the webs are arranged obliquely. It is thus achieved to comply with standards (Federal Safety Standards MVSS No. 108) which prescribe a possible load of 2.2 kg on the lamp bulb without deflecting it.
  • the motor vehicle light bulb shown in FIGS. 1 and 2 consists of a lamp bulb 1, a holding element 2 and a base part 3.
  • the lamp bulb 1 is supported on the pinch element by the holding element 2.
  • This holding element 2 advantageously consists of two identical shell halves 4 which have tabs 5 and angled tongues 6 on the side. By means of these tabs 5 and the tongues 6, these two shell halves 4 are connected to form a sleeve which surrounds the lamp pinch. Additional, partially punched tongues 7, which cooperate with depressions in the lamp pinch, give the connection a firm hold.
  • webs 8 are formed and bent back, the free ends of these webs 8 being connected to the base part 3.
  • a base part 3 made of plastic is provided for the lamp and the connection between the holding element 2 and base part 3 takes place by high-frequency heating.
  • the free end of the webs 8 has a bead 10 provided with openings 9 which presses into the base material after high-frequency heating. The openings are then penetrated by the base material.
  • the holding element 2 is made of stainless steel, which has a relatively poor thermal conductivity.
  • a recess 11 additionally reduces the heat transfer.
  • Kinks 12 on the webs increase the stability of the holding element 2. These are advantageously arranged at an angle to the longitudinal axis A.
