Definitions

  • the invention relates to a lamp for a rod-shaped fluorescent lamp provided at both ends with pin bases with an elongated support profile, the width of which is only slightly larger or smaller than the diameter of the lamp bulb and to which the socket housing, which is equipped with socket contacts on both sides, connects with each a slot for receiving the socket pins are provided when the lamp is inserted parallel to the axis.
  • Such lights are usually equipped with sockets, in which the lamp with its base pins is used axially parallel, after which a locking and contacting of the base pins with the socket contacts takes place by a quarter turn of the lamp about its longitudinal axis.
  • the luminaire is designed to be very narrow for formal reasons, i.e. their width can be only slightly larger or even smaller than the diameter of the lamp bulb, so standard lamp holders can no longer be used because they cannot be produced so small.
  • a lamp for a rod-shaped fluorescent lamp with an elongated support profile is known, the width of which is in the order of the lamp bulb.
  • the socket housings are arranged to be displaceable in the axial direction with respect to the carrier profile, ie the socket housings can be moved axially outwards from their normal operating position into a locked position move that the fluorescent lamp can be used or removed without further measures. Regardless of the fact that this is a relatively complex construction, the known lamp requires a large amount of space in the longitudinal direction. A light band arrangement is not possible with this.
  • the invention is therefore based on the object of providing an inexpensive luminaire with a narrow support profile, in which the lamp remains in a fixed position in relation to the support profile for the axially parallel insertion of the lamp into the holder housing.
  • the lamp is held in the socket housing with the aid of the intermediate pieces placed on the lamp base, without these having to be displaced in the axial direction relative to the carrier profile.
  • the length of the lamp is therefore not changed to replace the lamp.
  • the arrangement of the individual socket pins of the lamp on different sides of the crosspiece of the intermediate pieces fulfills the safety requirements according to which neither of the two socket pins may be touchable if the other pin is already in electrical connection with one of the socket contacts.
  • the cross bar is preferably S-shaped in its cross section.
  • the crossbar of the intermediate pieces can have a widening at the upper edge, which snaps into the slot of the socket housing like a lid.
  • the intermediate pieces for inserting the two socket pins each have two contact sleeves, which protrude in length beyond the socket pins and there interact with the socket contacts, which are located deep in the socket housing.
  • the socket contacts are so deep in the socket housings that when a lamp is inserted without spacers, its relatively short base pins cannot reach the socket contacts.
  • each intermediate piece has on its front side a cylinder sleeve which receives the lamp base.
  • the lamp according to Fig. 1 has an elongated channel-shaped support profile 1, on which both sides of the socket housing 2 made of e.g. Connect plastic.
  • the lamp serves to accommodate a rod-shaped fluorescent lamp 4 provided with pin bases 3 at both ends (cf. FIG. 2).
  • the two pin bases 3 of the fluorescent lamp 4 each have two base pins 5.
  • the ballasts required for the operation of the fluorescent lamp 4 such as a choke coil, starter and, if necessary, thermal fuse (not shown in the drawing). If the lamp 4 is operated with an electronic ballast, this can be installed in one of the socket housings 2.
  • each socket housing 2 is provided with a slot 7 for receiving the socket pins 5.
  • socket contacts 8 are provided, which are arranged one above the other.
  • Intermediate pieces 9 made of insulating material are placed on the lamp base 3 and are shown in more detail in FIGS. 3 to 5.
  • These intermediate pieces 9 consist of a plate-shaped plastic part 10, which has on its rear side a transverse web 11 which extends parallel to the base pins 5 and which has an S-shaped cross section (FIG. 5).
  • the transverse webs 11 penetrate into the slots 7 in the socket housing 2.
  • Each crossbar 11 has at its upper edge a widening 12 which snaps into the cover 7 surrounding the slot 7 wall of a lampholder housing 2, whereby the lamp 4 is held on the lamp.
  • the intermediate pieces 9 each have two longitudinally slotted contact sleeves 13 for inserting the two socket pins 5 of the lamp 4, which are considerably longer than the socket pins 5 and each extend on different sides of the crosspiece 11 (FIG. 5).
  • each intermediate piece 9 On its front side each intermediate piece 9 has a cylinder sleeve 14 which receives the lamp base 3. At the foot of the cylinder sleeve 14 there are two slot-like recesses 15 which serve to receive an insulating cover plate 16 (FIG. 3).
  • the intermediate pieces 9 are placed on the lamp base 3, the lamp base 3 being covered by the cylinder sleeve 14.
  • the base pins 5 of the lamp 4 penetrate into the contact sleeves 13 to form a large contact area.
  • the lamp 4 with the attached spacers 9 is displaced axially parallel to the support profile 1 in the direction of the arrow, the spacers 9 penetrating with their transverse webs 11 into the slots 7 of the socket housing 2 until the Snap the widenings 12 of the crossbars 11 into the wall of the socket housing 2 and close the slots 7 like a cover.
  • the two contact sleeves 13 lie on different sides of the crossbar 11, when the lamp 4 is inserted into the socket housing 2, each contact sleeve 13 can only come into electrical connection with the socket contact 8 assigned to it.
  • the contact between the two contact sleeves 13 and their socket contacts 8 thus occurs simultaneously, with no contact of the contacts from the outside being possible. -
  • the removal or replacement of the lamp 4 is done in reverse order.
