Definitions

  • the invention relates to an electric lamp according to the preamble of the claim 1.
  • Such an electric lamp is for example in the international patent application WO 98/27567 discloses.
  • This patent application describes an electrical Lamp, in particular a motor vehicle headlight lamp, with a glass one Lamp bulb, a filament arranged therein and one made of metal and Plastic parts existing lamp base.
  • the lamp base has a metallic Holder part for the lamp bulb, an associated ring-shaped metallic Carrier sleeve and a provided with the electrical connections of the lamp Plastic base part, in which the carrier sleeve is anchored, for fastening the
  • the lamp in the headlight reflector is the lamp base with an arched Leaf spring trained pressure spring equipped.
  • the leaf spring ends are in contact the inner wall of the annular support sleeve, while a V-shaped section the leaf spring extends through an opening in the carrier sleeve.
  • the leaf spring is fixed in the plastic base part.
  • the electric lamp according to the invention has a lamp base, a translucent Lamp bulb and at least one enclosed by the lamp bulb Illuminant.
  • the lamp base has a metallic holder part for the Lamp bulb, an annular metallic support sleeve connected to the holder part and a plastic base part provided with the electrical connections of the lamp, in which the carrier sleeve is anchored.
  • Lamp in a headlight reflector is the lamp base with a designed as a leaf spring pressure spring, which ensures that the Lamp with a clamp seat in the reflector opening of the lamp holder Headlight is held.
  • the pressure spring lies on the inner wall of the ring-shaped one Carrier sleeve and engages through an opening in the carrier sleeve.
  • the carrier sleeve has two inwardly angled tabs on, which are each crossed with one end of the leaf spring, and between which the leaf spring is arranged with a press fit.
  • This causes the pressure spring to open reliable and simple way, that is, without additional fasteners, attached directly to the carrier sleeve.
  • the angled tabs are from the Shaped material of the carrier sleeve.
  • the pressure spring designed as a leaf spring is with a press fit between the two angled tabs that end the leaf spring serve as a stop, arranged.
  • Each end of the leaf spring is advantageously equipped with at least two teeth, between which the respective inwardly angled tab of the carrier sleeve is arranged.
  • the aforementioned teeth allow the entanglement of each Leaf spring end with the corresponding tab of the carrier sleeve.
  • the angled tabs form a point with the carrier sleeve Angle, with each leaf spring end in the range of the acute angle between the corresponding angled tab and the support sleeve wall is arranged.
  • the tabs also act as a guide for the leaf spring ends, so that the ends of the leaf spring due to the mechanical tension in the leaf spring is clamped between the tabs and the carrier sleeve wall.
  • the leaf spring trained pressure spring of the lamp according to the invention advantageously has a V-shaped section through the opening in the carrier sleeve picks up and two U-shaped sections, between which the V-shaped section is arranged, the U-shaped sections each having a V-leg of the V-shaped Connect the section to one end of the leaf spring.
  • the U-shaped Sections in the leaf spring is advantageously a mechanical tension and the clamp of the leaf spring between the angled tabs of the Carrier sleeve generated.
  • the V-shaped section through the breakthrough in the Carrier sleeve engages after the lamp is installed in the lamp socket Headlight reflector opening resiliently.
  • connection area between the two legs of the V-shaped section is advantageous rounded to the contact area between the pressure spring and lamp holder enlarge and to facilitate the assembly of the lamp in the socket.
  • the leaf spring lies in the transition areas between the V-shaped Section and the U-shaped sections and in the transition areas between the U-shaped sections and the respective leaf spring end on the Inner wall of the carrier sleeve. This increases the stability of the attachment the pressure spring.
  • the preferred embodiment of the invention is a Single-filament halogen lamp for use in a motor vehicle headlight is provided.
  • This lamp has a glass, essentially cylindrical Lamp bulb 10 with a gas-tight squeeze foot 10a.
  • the Dome 10b of lamp bulb 10 is provided with a light-absorbing coating.
  • a light source that is aligned parallel to the lamp bulb axis serves as the light source Incandescent filament 11, which is electrically conductive with two led out of the squeezing foot 10a, Power supply lines 12, 13 made of molybdenum wire are connected.
  • the squeezing foot 10a of the lamp bulb 10 is in a metallic holder from the cup-like holder part 14a, the intermediate ring 14e and the annular Carrier sleeve 14b is fixed.
  • the lamp base is also provided with the electrical connections 16, 17 of the lamp Plastic base part 15 in which the annular metallic support sleeve 14b is anchored.
  • the carrier sleeve 14b has three reference lugs lying in one plane 14c and a pressure spring 100 for mounting the lamp in the reflector 20 a motor vehicle headlight.
  • the reflector 20 is sealed by means of a silicone sealing ring 19 which on the outer wall 20b of the reflector 20 and abuts the plastic base part 15.
  • the construction of the lamp is shown in FIG of the preferred embodiment and their use in a headlight schematically shown.
  • FIG. 2 shows details of the arrangement of the lamp in the reflector 20 of the motor vehicle headlight.
  • the three reference lugs 14c engage in the lamp socket Mounting opening 21 of the reflector 20 and lie on the inside 20a of the reflector 20. They 14c are equidistant over the circumference of the ring-shaped Carrier sleeve 14b distributed.
  • the pressure spring 100 of the carrier sleeve 14b is below a first reference lug 14c and resiliently on the edge 22 of the Lamp mounting opening 21 on.
  • To attach the pressure spring 100 to the Carrier sleeve 14b serve two molded onto the annular carrier sleeve 14b, according to internally angled tabs 14d, between which the leaf spring Pressure spring 100 with a clamp seat is arranged ( Figure 3). Form the tabs 14d with the support sleeve wall at an acute angle.
  • the leaf spring 100 consists of a Spring steel. Their shape is shown in Figures 4 and 5.
  • the leaf spring 100 has a V-shaped section 101 which is between two U-shaped Sections 102, 103 is arranged.
  • the U-shaped sections 102, 103 each connect one leg of the V-shaped section 101 to a leaf spring end 104, 105.
  • Each leaf spring end 104, 105 has two teeth 104a, 105a equipped, between each of which the corresponding, from the support sleeve 14b angled tab 14d is arranged ( Figure 3). Close teeth 104a, 105a with the leaf spring ends 104, 105 an angle of 105 degrees.
  • the V-shaped Section 101 extends through an opening in the carrier sleeve 14b and the one arranged between the two legs of the V-shaped section 101, Rounded connection area 101a lies on the edge after lamp assembly 22 of the reflector opening 21 designed as a lamp holder.
  • the leaf spring 100 lies in the transition areas between the V-shaped section 101 and the U-shaped sections 102, 103 and in the transition areas between the U-shaped sections 102, 103 and the respective leaf spring end 104, 105 on the inner wall of the carrier sleeve 14b.
  • the outside of the carrier sleeve 14b each have a depression 14f.
  • the edge 22 of the lamp mounting opening 21 of the reference lugs 14c Reflector 20 each have a prismatic contact surface 22a.
  • the outside of the carrier sleeve 14b of the lamp base lies on these two prismatic contact surfaces 22a with a press fit.
  • the clamping effect is generated by means of the pressure spring 100.
  • the depressions 14f ensure that the burr which may be burred Outer edge 22a2 of the edge 22 of the mounting opening 21 contact-free Lamp base and in particular to the support sleeve 14b is arranged.
