Definitions

  • the present invention refers to a lighting device with a rotating lamp, of the type comprising a lamp socket structure apt to receive a lamp, e.g. in form of a fluorescent lamp.
  • lamps having an oblong, substantially tubular shape having a single fixing end in correspondence of one of the two ends of the lamp.
  • these lamps are formed by fluorescent lamps having a plugging mechanism in correspondence of a fixing end, operating as a base of the lamp and being apt to be plugged in a respective socket provided in the lamp socket structure.
  • the space to be provided should be wide enough to allow the positioning of the whole lamp, comprising the base and the plug.
  • an amount of that space, opposed to the plug remains clear and substantially unused.
  • the lamp socket structures for the above mentioned kind of lamps should have be oversized, thus requiring a high use of space during storage and a higher cost for materials.
  • the technical problem underlying the present invention is to provide a lighting device allowing to overcome the drawback mentioned above with reference to the known art.
  • a device as above specified characterized by that the socket of the lamp and the lamp socket structure are connected by means of a joint allowing the socket to rotate relative to the lamp socket structure, from a plugging position, wherein the lamp is rotated and external to the lamp socket structure, to a working position wherein the lamp rests in the lamp socket structure.
  • the main advantage of the lighting device according to the present invention lies in that it allows an easy plugging, without positioning the lamp in the lamp socket structure, and a size reduction of such structure.
  • a lighting device is overall shown with the reference number 1. It comprises a lamp socket structure 2 closed by a transparent wall in an operative arrangement, and comprising an opening 4 apt to house a lamp 5, in particular a fluorescent lamp.
  • the lamp 5 is oblong shaped, substantially tubular, being formed of two sided parallel tubes, connected at one end. It comprises a single fixing end 6, opposed to the end connecting the two tubes, provided with a plugging mechanism 7 that should be plugged in a corresponding socket 8 provided in the lamp socket structure 2.
  • the lamp socket structure 2 is oblong shaped, flat and rectangular, and it is suitable to be fixed on a wall to work as, e.g., an emergency lamp.
  • the electronic circuitry (not shown) required for turning on and off the lamp.
  • Such circuitry powered by a battery and/or by supply mains, is connected to the socket 8 by means of suitable cables.
  • the socket 8 comprises a plurality of holes 9 holding the electrical contacts connecting to plugs 10 of the plugging mechanism 7.
  • the lamp socket structure 2 opening 4 also contains supports 12 for the lamp and a fixing device 13 of the lamp 5 free end 14, that will be described in the following.
  • the lamp 5 socket 8 and the lamp socket structure 2 are connected by means of a joint allowing the socket 8 to rotate relative to the lamp socket structure 2.
  • the socket 8 could be rotated in a plugging position ( Figure 4A ), wherein the lamp 5 is rotated and it is external to the lamp socket structure 2 and, therefore, it can be easily plugged in the socket 8. Then, the lamp 5 is laid down ( figure 4B ) in the lamp socket structure 1 until it reaches an operative position ( figure 4C ), in which the transparent cover can be placed on the structure 2.
  • the socket 8 is formed by an enbloc part that could be inserted in a frame 15 provided with a clamping device and made of elastic material, e.g. plastic, so as to be able to easily plug and unplug the socket 8 ( Figures 2 , 5A. 5B, 5C ).
  • the frame 15 has pins on opposed ends that can be inserted in suitable seats in the lamp socket structure 2.
  • the pins can be formed in the structure 2 and the seats in the frame 15.
  • the enbloc socket 8 is provided with pins or holes apt to cooperate with corresponding holes or pins of the lamp socket structure 2.
  • the device 1 comprises the above mentioned fixing device 13 of the lamp 5 free end 14.
  • It comprises a seat 16 obtained on the opening 4 bottom of the lamp socket structure 2, into which a fixing element 17 is inserted so that it can move longitudinally, i.e. parallel to the lamp 5 development.
  • the seat 16 comprises an inserting hole of said element 17 and a longitudinal guide 18, at the sides thereof pawls 19 being provided ( Figure 6A ).
  • the fixing element 17 has a pair of elastic arms 20 with an end shaped such that it realizes a clamping spike cooperating with the pawls ( Figure 6B ). Accordingly, the fixing element 17 can be translated along the guide 18 remaining in a preset position, if it is not subjected to any load stress ( Figure 6C ).
  • the pawls 19, forming on each side of the guide 18 a continuous rack, and the above described clamping spike allow to finely adjust the position of the fixing element 17, and to push it according to a direction concordant and opposite in sign to the unplugging one. They provide stopping means of the fixing element 17 in a certain position.
  • the fixing element 17 comprises a tab 21 under which the free end of the lamp 5 is received.
  • the lamp 5 is rotated so that it is adjacent to the lamp socket structure 2 in the opening 4 ( figure 7A ), a user can properly move the fixing element 17 of the device 13 ( figure 7B ) until the lamp 5 free end is compressed. Such end will be restrained by the tab 21 ( figure 7C ) that could be advantageously made of elastic material such that it can slightly provide an elastic pressure on the lamp 5.
  • the lamp 5 remains fixed in its position and it not affected by vibrations or other movements that could cause the unplugging of the plug 7 from the socket 8.
  • fixing device could envisage other modifications.
  • it can envisage the use of a snap hook keeping the lamp 5 in place.
  • it can comprise an elastic element on the opening 4 edge, eventually embedded in the same edge of the lamp socket structure 2.
  • the present device could be modified to receive any substantially oblong shaped lamp, fluorescent, energy saving or of other type.
  • connection between lamp and structure could be obtained by a device such as the one above described or even by a different device, e.g. with a threaded screw.
