Definitions

  • the present invention broadly relates to an improved street lantern or similar lighting fixture.
  • Another important object of the present invention is the provision of an improved street lantern which can be supported in a balanced manner either by an overhead support or a post, is relatively inexpensive to manufacture, quite simple in construction, easy to service, and positively prevents the entry of dust into the lamp compartment.
  • the inventive street lantern or lamp is generally characterized by the features that, the globe or housing is symmetrically arranged with respect to the reflector, encircling the latter in spaced relation therefrom, and that the reflector in turn encircles the lamp in a cap or cover-like manner. Additionally, at the face or side of the globe where the light departs there is provided an at least partially detachable cover unit which has a light permeable or transmissive central portion, the marginal zone of which in the closed position of such cover unit cooperates with the edge or periphery of the reflector to provide a dustproof obturation of the lamp compartment formed by the reflector.
  • FIGURE 1 is a vertical sectional view taken through a street lantern designed according to the present invention, and which is connected to a horizontal mast rod or post; and
  • FIGURE 2 is a fragmentary, vertical sectional view of the street lantern of FIGURE 1, depicted for the purpose of illustrating its mode of securement to an overhead support.
  • the street lantern or lighting fixture A illustrated therein incorporates a reflector 1 open towards its bottom or lower end, and which in the illustrated embodiment is symmetrically surrounded or encircled by a substantially bell-shaped housing or globe 2.
  • the globe 2 is advantageously constructed to be step-shaped, with the reduced upper portion 3 extending upwardly in the illustrated embodiment, whereas the open side or end of the globe 2 situated opposite the reduced portion 3 is closeable by means of a cover member 4.
  • the cover member 4 is hinged ly connected to the left side of the globe 2 by means of a hinge joint 5 or the like, and in its closed position is lockable by means of a quick-closing screw 6 or otherwise arranged at the side of the globe 2 opposite the hinge joint 5.
  • This cover member 4 is advantageously provided with a central portion 4a which permits the transmission or passage of light, preferably formed from a synthetic glass trough, and which in the closed position of the aforesaid cover member seals in a dustproof manner the lamp compartment 7 formed by the reflector 1, for which purpose there is advantageously provided at the lower marginal edge 1a of the reflector 1 an additional seal 8 against which bears the shoulder-like edges 4b of the synthetic glass trough, that is, the central portion 4a.
  • the cover member 4 is provided at both sides of the central portion 4a with air slots 9 or the like which perm-it of air passage.
  • a ventilator 10 is arranged at the inner face of the cover member 4 and adjacent the air slots 9 depicted at the left side of the arrangement. This ventilator 10 extends into the compartment 11 of the compartments 11 and 11a appearing at both sides of the reflector 1 and formed between such reflector and the internal walls of the globe 2.
  • a locking coil 12 necessary for the lamp circuit as Well as a capacitor 13
  • an additional coil 14 is connected to a support plate 15 disposed in the upper region of the globe 2 and which is rigidly connected therewith by any suitable connecting means or expedients.
  • the reflector 1 is screwed, as at lb, or otherwise connected in spaced relation to the support plate 15, in the manner shown in FIGURE 1, and such that the air circulating within the lantern can freely flow between the support plate 15 and the reflector 1.
  • a lamp sock t 16 Internally of the reflector 1 there is additionally arranged a lamp sock t 16 in which a vapor lamp 17 or otherwise can be threaded.
  • the construction of the globe 2 and the arrangement of the reflector 1 in the center of the globe 2 permits of a fault less circulation of air and therewith a cooling of the internal compartments of such globe, Without the dust particles entrained by the air being able to enter the lamp compartment 7 of the reflector 1.
  • the articulated cover member 4 which can be locked in position by the quick-locking screw 6 permits for a rapid and facile replacement of the vapor lamp 17.
  • the jacket surface of the reduced upper portion 3 of the globe 2 is provided with an opening 19 through which piercingly extends the free end of the aforesaid mast or post extension 18.
  • a pair of mast fastening means or clamps 20 which are secured to the support plate 15.
  • a support angle member 21 preferably seated upon the support plate and to which there is connected a connection terminal 22 for the conductor wires or electric leads which are led through the mast extension 18.
  • traction relief means 23 In order to relieve the conductors there can be further provided.
  • the reduced portion 3 is provided, in accordance with FIG- URE 2, and externally thereof at the frontal face with a cable stirrup 24, the free ends of which are fixedly clamped by suitable clamp means 24a to an overhead suspension cable 25.
  • a stufling box 26 in the jacket surface of the reduced upper portion 3 and through which there is lead the conductors to the connecting terminal 22 disposed internally of the aforesaid reduced upper portion 3.
  • the described street lantern thus permits a selective suspension upon overhead supports as Well as also an attachment to mast rods or the like, without considerable changes having to be undertaken with the street lantern.
  • the street lantern can be initially prepared for connection to masts and to overhead supports to such a degree that if the street lantern is to be suspended at an overhead support then only the cable stirrup 24 must be screwed thereon.
  • the mast fastening means can be removed. It is, however, also conceivable to manufacture the street lantern such that after the predetermined bringing thereof to the place of erection, either the opening 19 is produced and the fastening means threaded thereon, or the stufling box 27 and the cable stirrup 24 is applied.
  • Street lantern comprising a hollow outer globe member including an open end for the departure of light, a reflector arranged within said outer globe member, said outer globe member encircling said reflector in spaced relation to provide a flow passage externally of said reflector for the circulation of air for cooling said reflector, said outer globe member being symmetrically disposed With respect to said reflector, said reflector providing a lamp compartment, at least one lamp situated Within said lamp compartment, said reflector surrounding said lamp in hood-like manner, electric circuit components for said lamp, at least a partially detachable cover member provided at said open end of said outer globe member, said cover member including a light transmissive central portion having marginal portions bearing in sealing manner against the outer extremities of said reflector in the closed position of said cover member to provide dustproof sealing of said lamp compartment formed by said reflector, said cover member being provided with slot means at both sides of said light transmissive central portion and outside the confines of said reflector, said slot means communicating with said flow passage for the circulation of air, and ventilator means located adjacent the slot means disposed at
