Definitions

  • An electric lamp has a base formed of two half sections made of insulating material.
  • the base is aligned on and attached to the lamp by positioning the half sections on contact prongs, and by holding the two halves together through the action of a holding means such as a screw and nut or rivet with the screw or rivet extending through the interior of both half sections of the base, and the method of assembling the base to the lamp.
  • the invention relates generally to electric lamps. More particularly, the invention relates to a base structure and a method of assembling the base to an electric lamp of the type that can be plugged directly into a receptacle.
  • the objects of the invention are accomplished .by providing a two-piece base made of insulating material and aligned with and attached to the lamp through the action of contact prongs and a holdingmeans such as a screw and a nut or a rivet.
  • the lamp of the invention contains contact posts, or lead-in conductors, which are hermetically sealed to a reflector section. Contact prongs are attached to the posts by soldering, for example, and a portion of the c'ontactprongs extends in either direction beyond the .post.
  • One of the insulating base sections contains an alignment slot or slots on its interior surface which is positioned against a portion of the contact prongs to align the base section in a predetermined position. This insulating base portion also contains a hole which extends through the base wall.
  • the other half of the insulating base section contains two openings which extend'through the base section wall for receiving the socket prongs of the contact member. This portion also contains a hole which extends through the base wall and is aligned withthe hole in the first basesection.
  • a screw is inserted into the hole which extends through both base section walls,'and a nut is attached at an end opposite the screw head to firmly draw the both half section's close together to form'the base.
  • An alternative method of attaching the two base sections is to insert a rivet instead of the screw andnut and peen over one end of the rivet to provide the force which draws the-two half sections together.
  • FIG. 1 is an exploded view of the various components of the base-lamp of the invention.
  • FIG. 2 is a perspective view of the assembled baselamp of the invention.
  • an electric lamp has a glass envelope 31 comprised of reflector section 11 and cover portion 12. Ferrules or lead-in conductors 13 are hermetically sealed in the reflector section to an energy translation device, not shown, such as a filament or electrodes.
  • a typical lamp which can utilize the invention is a PAR 46, Medium Flood, 200 watt, 120 volt.
  • Contact prongs l4 and 15 are attached to the ferrules by soldering, for example. A portion of each contact prong may be cut and bent around the ferrules as shown at 16 and 17 in order to give a reliable connection between the contact prong and the be clipped off inasmuch as they were not utilized after I ferrule.
  • a portion of the prongs 14 and 15 may be bent back upon themselves as shown at 18 and 19 in order to form socket prongs for insertion into a receptacle.
  • extensions 20 and 21 At the other end of the contact prongs are extensions 20 and 21 which will aid in the alignment of the insulating base portion. In prior art lamps, extensions 20 and 21 would the bent portion had been attached to the ferrules.
  • Insulating base sections 23 and 24 can be made of a ceramic material or any other insulating material which can give the required strength, temperature resistance and insulating property.
  • Base section 23 contains alignment slots 27 and hole 28.
  • the alignment slots do not extend through the thickness or wall of the base section, whereas hole 28 goes directly through the wall.
  • Base section 24 contains contact prong openings 29 and hole 30. Holes 28 and 30 are positioned in the base sections such thatthey are in direct alignment when placed prongs.
  • first contacts 14 and 15 are slit and bent so that the,
  • bent portion may be attached to the ferrules 13 by soldering, for example, as shown at 16 and 17. After the ment slots 27 do not extend through the base wall and section 23. This allows bent-back portions 18 and.19 to I extend beyond the slot 29 so that they may make electrical contact with the female portion of a receptacle.
  • An electric lamp comprising a glass envelope, an energy translationdevice connected to lead-in conductors which are hermetically sealed to said envelope, wherein the improvement comprises a base structure comprising contact prongs attached to the lead-in conductors and extending away from said lead-in conductors in both directions, said contact prongs comprising socket prongs at one end and a predetermined length extended away from said lead-in conductor at the other end, and two base sections made of insulating material, one of said base sections containing a hole and at least one alignment slot for receiving at least one of said predetermined lengths of said contact prong, said alignment slot formed as an indentation in the wall of said first base section, said alignment slot not extending through the wall of said first base section, said other base section containing two through openings for receiving said contact prongs and a hole in alignment with the hole of said first base section, said holes adapted to receiving a clamping means, and a clamping means inserted in and through said holes to firmly hold said base sections together.
  • An electric lamp as claimed in claim 1 wherein a portion of said predetermined lengths is cut and bent around and attached to a part of the lead-in conductor.
  • An electric lamp comprising a glass envelope, having a reflector portion hermetically sealed to a cover, a filament connected to lead-in conductors which are also hermetically sealed in said envelope, wherein the improvement comprises a base structure comprising contact prongs attached to the lead-in conductors and extending away from said lead-in conductors in both directions, said contact prongs comprising socket prongs at one end and a predetermined length extended away from said lead-in conductor at the other end, two base sections made of an insulating material, one of said base sections containing a hole and two alignment slots for receiving said predetermined lengths of said contact prong member, said alignment slots being formed as indentations in the wall of said first base section, said alignment slots not extending through the wall of said first base section, said other base section containing two through openings for receiving said contact prongs and a hole in alignment with the hole of said first base section, said holes adapted to receiving a clamping means, and a clamping means inserted in and through said holes to firmly
