Definitions

  • the invention relates to a fluorescent lamp with an elongated light bar for receiving the devices and wiring required for operating the lamp and arranged at the ends of the light bar end caps and sockets for receiving the contact pins of the lamp, with at least one socket in each end of the light bar a component manufactured separately from the front end is arranged, and this component can be pivoted about an axis lying in the front end and lying parallel to the longitudinal axis of the beam, and the axis is formed by a pin fastened in the base, which pin connects the front end: interspersed and has a head-like widening at the free end.
  • the front end of the light bar consists of a plate with two tab-like, spaced apart and enclosing an acute angle between them tabs which have transverse longitudinal slots.
  • tab-like approaches are - on the inside of the plate, the components supporting the frame.
  • a pin is fastened in each component, which penetrates the longitudinal slot of the tab-like extension and has a mushroom-like widening.
  • the U-shaped lamp bar is open to the lamp side and this open side can be closed by a lid. On its narrow sides, this cover has two recesses for receiving the components supporting the frame, between which a leaf spring is riveted.
  • this leaf spring presses with its free ends against the structure supporting the frame divide and spread these apart, since these components can be pivoted to the extent of the longitudinal slots mentioned.
  • This known construction has the task of reducing and reducing the outer dimensions of the lamp bar, including the sockets it supports, for packaging and shipping purposes. During the operational assembly of the light bar mentioned, the two components supporting the socket can no longer be adjusted, since their position is clearly predetermined by the action of the leaf spring mentioned in connection with the stops.
  • the components having the holder have tabs, the free ends of which in turn have a threaded screw.
  • These threaded screws are mounted in an arcuate slot in the front end of the lamp bar.
  • a clamping screw which is screwed onto this threaded screw, the component supporting the socket can be adjusted and fixed with regard to its angular position in relation to the light beam. Any angular positions can be selected within predefined limits, this construction having an adjustment range of approximately 60 angular degrees.
  • a tool (wrench or screwdriver) is required for the desired setting, and also that this construction is not visually satisfactory.
  • There is a slit-shaped opening on the face through which dust can penetrate into the interior of the light bar, and the protruding screw head or the protruding screw nut also represents an optically unsatisfactory solution.
  • this shaft penetrates a helical spring, which is supported on the one hand on the aforementioned widening located inside the lamp bar and on the other hand on the inside of the forehead termination and preferably the abutting surfaces of the forehead termination on the one hand and the component supporting the socket on the other hand have latching elements which are operatively connected to one another, such as bores and pins, notches and springs or the like.
  • This adjustment mechanism according to the invention is not visible from the outside.
  • the abutting surfaces of the end closure on the one hand and the component supporting the socket on the other have locking elements that are operatively connected to one another, such as bores and pins, notches and springs or the like. These locking elements in conjunction with the helical spring penetrated by the pin ensure sufficient securing of the set and selected angular position even under extreme conditions. Nevertheless, this adjustment mechanism is not visible and not recognizable from the outside, so that optically satisfactory solutions can be achieved by the proposal according to the invention.
  • this beam 1 consists of an elongated light bar 1, which is made of sheet metal or plastic and which usually houses the devices and wiring required for the operation of the light 2.
  • This bar can be left hollow or it can be filled with foam.
  • this beam 1 is closed by end closures 3 which have a cross section which corresponds essentially to the cross section of the beam and which are firmly connected to the beam in a suitable manner.
  • Components 4 are now arranged on these end terminations 3, which carry a holder 5 for receiving the contact pins of the lamp 2.
  • These components 4 are manufactured separately from the end closures 3 and pivotally connected to them, specifically about the axis 6, which is arranged laterally with respect to the socket 5 of the component 4 and is parallel to the longitudinal extension of the beam 1.
  • the front end 3 and the holder 4 are two separate components that are functionally connected to each other on and in the lamp.
  • the holder 5 supporting component 4 can be pivoted perpendicular to the plane of the drawing, so that the lamp is extremely adaptable, which is particularly desirable when a lamp of this type must be used in confined spaces.
  • the mentioned pivot axis 6 is, as shown in Fig. 2 in section, by a cap screw? formed with her a threaded end is screwed into a threaded sleeve 8 cast in the component 4.
  • This screw 7 passes through the front end 3 and a coil spring 9, which is supported on the one hand on the head 10 of the screw and on the other hand on the inside of the front end 3. Thanks to this mounting, the component 4 carrying the socket 5 can not only be pivoted perpendicularly to the plane of the drawing, as already described above, this special mounting also allows the component 4 to move in the direction of the arrow 11 (FIG. 2), which compensates for different Lamp lengths is required.
  • the fluorescent lamps have considerable tolerances in terms of their length, so that such a possibility of adaptation is extremely important for proper contact.
  • the lamp shown in FIGS. 1 and 2 is a single-lamp lamp.
  • Locking elements which are operatively connected to one another can be provided between the abutting surfaces of the front end 3 on the one hand and the component 4 carrying the mount 5 on the other hand.
  • bores lying on a surface on a circular line around axis 6 can be arranged and on the counter surface a small pin which can snap into these bores, so that the components engage firmly in a predetermined angular position and are held by this grid .
  • notches and springs can also be provided, which enable such engagement.
  • This is shown schematically at the front end 3 in FIG. 9, wedge-shaped depressions 12 being arranged in a circle around the axis 6, which correspond to corresponding rib-like elevations on the counterpart 4.
  • FIGS. 5 and 6 or 7 and 8 in plan view and side view, from which it can be seen that these components or frame carriers over their length 1 in their strength s or
  • the respective thicker sections of these components 4 ', 4 carry the sockets 5' and 5"; the tapered sections lie one above the other when they are installed correctly (see FIGS. 3 and 4).
  • sockets on a component or frame support 4, which is not shown in the drawings. These sockets then expediently lie one behind the other as seen in the pivoting direction.
  • 3 or 3 'slots are provided in the end closure, which, however, are covered by the adjoining surface of the mount carrier or component 4, 4', 4 ", so that they cannot be seen from the outside.
