Definitions

  • JOSEPHUS F. RIJCKAERT mi A AGENT United States Patent O 3,262,001 ELECTRIC LAMP Josephus Franciscus Rijckeart, Emmasingel, Eindhoven,
  • An electric lamp in which the lamp cap and the portion of the lamp vessel surrounded by it are secured together by means of a metallic connecting body is known.
  • This structure is used, for example, for the purpose of correctly adjusting the filament inside the lamp with respect to the lamp cap. This may be important, for example, if the relevant lamp is intended for the lighting of vehicles or projection and, during operation, must occupy a predetermined position relative to the associated optical means in order to obtain a maximum eiect.
  • a lamp according to the invention is characterized in that the connecting body between the lamp cap and the portion of the lamp vessel surrounded by it has at least two strip-shaped parts bridging the distance between the inner side of the lamp cap and the portion of the lamp vessel surrounded by it, the larger transverse dimension of said parts being equally directed as the axis of the lamp cap.
  • the advantage is obtained that there is not only a possibility of displacement in the direction of the axis of the lamp cap between the lat-ter and the lamp vessel, but also as a result of the deformability of the stripshaped parts, said vessel is adjustable over a comp-aratively large distance in the transverse direction relative to the lamp cap and can readily be fixed in position.
  • connecting body could be formed by a sleeve tightly surrounding the seal and to which the stripshaped parts are attached, for example by soldering, in one advantageous embodiment of the invention it is preferable Ito build up the whole of the connecting body of substantially identical structural parts made from metal strips.
  • the lamp once adjusted tends to move with respect to the lamp cap, for example due to vibration, a risk resulting from the deformability of the strip-shaped parts
  • FIGURE 1 is an elevational view of a irst embodiment of the lamp according to the invention.
  • FIGURE 2 shows the same lamp, partly in side view and partly in section
  • FIGURE 3 is a sectional View of the lamp of FIGURE 2, taken on the plane III-III;
  • FIGURE 4 is -a perspective View of one of the parts of the connecting body used in the lamp shown in FIGURES 1, 2 and 3;
  • FIGURE 5 shows, partly in side view and partly in section, a second embodiment of the lamp according to the invention
  • FIGURE 6 is a sectional view taken on the plane VI-VI of FIGURE 5 and FIGURE 7 shows one of the parts of the connecting body as used in the embodiment of the lamp shown in FIGURES 5 and 6.
  • the lamp shown in FIGURES 1 and 2 comprises a bulb 10 closed at each end by seals 11 and 12 respectively.
  • a iilament 13 is mounted in the lamp between supporting Wires 14 and 15.
  • Molybdenum foils 16 and 17 respectively are included in the said supporting wires.
  • the bulb has a protrusion which is the sealing tip of an exhaust tube 18.
  • the lamp is provided with a cylindrical metallic cap 19 for iixing on a lamp holder, not shown. To this end, pins 20 and 21 are provided.
  • FIG. 4 Two of the structural parts shown in FIGURE 4 are lixed on the seal 12 so as to intimately surround it.
  • the structural par-t shown in FIGURE 4 has apertures 24 and 25 into which iit glass projections 26 and 27 provided on the seal 12.
  • the two structural parts 28 and 29 are connected together by welding or soldering through stripshaped zones indicated by 30 and 31 in FIGURE 3.
  • the connecting body comprising the parts 28 and 29 is thus xed on the seal 12 in a reliable manner.
  • Strip-shaped portions 32 and 33 of the two structural parts are resilient and their free ends are spaced from each other a distance ygreater than the internal diameter of the cap 19. When moved towards each other these ends can be slipped in this position into the lamp cap 19, thereby engaging the inner periphery thereof. Now, the situation shown in FIG.
  • the distance between the center of the lilament 13 and a reference surface on the lamp cap 19 may be adjusted. This is effected by displacing the lamp vessel, together with the connecting body, in the longitudinal direction inside the lamp cap.
  • the reference plane may be formed, for example, by the center lines of the pins 20 and 21.
  • the free portions of the stripshaped projections are bent. Since the lon-ger dimension of these strips is equally directed as the longitudinal axis of the lamp cap, such bending results in a lateral displacement of the lamp vessel in the lamp cap. In the ultimate position the portions of the projections which engage the inner side of the lamp cap may be secured to the lamp cap by welding or soldering.
  • the structures of the lamp Vessel 40 and the lamp cap 41 are identical with those shown in FIGURES l, 2 and 3.
  • the connecting body comprises two parts also in this case, but has a shape slightly diierent from the connecting body shown in FIGURES 1 to 4.
  • Each part of the connecting body has, as may especially be seen from FIGURE 7, a at portion 42. This may be provided with apertures 43 and 44 to allow the passage of glass projections 45 and 46 provided on a seal 47 of the lamp.
  • Each structural part furthermore has two strips indicated by 48 and 49 in FIGURE 7.
  • the central portion 42 has, at its upper side, tongues 50a-5M and Sla-51h respectively which have been bent twice.
  • the portions 50a and 51a of the tongues form part of the envelope surrounding the seal 47.
  • the portions 50h and 51b of the said tongues which are further remote, serve to secure together the opposing structural parts by a soldering or welding operation. This may be seen from FIGURE 6.
  • the lamp vessel may be fixed relative to fthe lamp cap by providing a solidifying mass, such as cement, in the space which subsists in the lamp cap after the provision of the seal and the connecting body.
  • seal of the lamp may have any cross-section differing from the substantially rectangular cross-section shown.
  • An electric lamp comprising a bulb having at least one projection thereon, a lament, first means mounting said lament within said bulb, a lamp cap, and second means mounting one end of said bulb in said lamp cap, said second means including two strip-shaped parts positioning said one end of the bulb in spaced relationship with the inner side of said lamp cap, one of said stripshaped parts being provided with an aperture through which the projection of said bulb protrudes, said stripshaped parts being provided with bent tongues in adjacent pairs that abut each other and are secured together.
