Definitions

  • the invention relates to an operating light with at least one main lamp arranged at a desired point and a replacement lamp arranged at a waiting point located near the desired point, the main lamp and the replacement lamp being held and controlled in such an adjustable manner that when the main lamp burns, it moves away from the desired point and the Replacement lamp is moved from the waiting point to the target point and held there.
  • the invention also relates to a method for replacing the main and replacement lamp in such an operating light.
  • Such operating lights are known in different versions (US-PS 5 023 515, DE-U-93 11 156 and 93 19 274; DE-OS 39 20 494).
  • the two lamps are moved over complex parallel guides (US Pat. No. 5,023,515), rotating platforms (DE-OS 39 20 494) or by means of a rocker (DE-GBM 93 11 156) when the main lamp burns out and is replaced by a replacement lamp is.
  • the latter solutions are complex and require a relatively large amount of space.
  • the replacement lamp is located at least partially in the beam path of the main lamp and thus shadows part of the light emitted by it.
  • the aim of the present invention is to create a further operating light of the type mentioned at the beginning.
  • a simple, safe and inexpensive positioning device is to be created and as little light as possible from the main lamp is to be shadowed by the replacement lamp.
  • the idea of the invention is therefore to be seen in the fact that the two lamps are not moved at the same time when they are replaced, but rather in chronological succession and are mounted on rotating or sliding bodies which can be moved independently of one another. In this way it is e.g. B. possible to move the already blown and therefore worthless main lamp quickly and without regard to vibrations etc. from the focal point (target position) and then carefully and gently bring the replacement lamp to the target position.
  • a structurally particularly advantageous embodiment is characterized by claim 2.
  • the two swivel brackets are structurally simple and can be accommodated compactly.
  • the use of rotating sleeves arranged one behind the other for the swivel brackets is particularly advantageous. While the rotary sleeves can in principle be driven separately by motor, it is preferred if, according to claim 3, only one motor is used. Due to this design, the main lamp support arm can be moved very quickly away from the desired position by the spring action and the motor, which is also under the action of the spring. Since the same motor then conveys the replacement lamp to the desired point against another spring, so the motor must now work against spring force, the replacement lamp is retracted to the Desired point without the provision of any switching carefully and vibration-free, so that damage to the replacement lamp when changing the lamp is effectively avoided.
  • a main lamp 11 of an operating light (not shown in detail) is mounted on a swivel bracket 15 via a base 30, which has a support arm 17 which extends from the base 30 to a rotating sleeve 23 which passes through a bearing which is only indicated schematically 33 is rotatably mounted about an axis of rotation 32.
  • a drive train 36 which can also contain a reduction gear
  • the rotary sleeve 23 is connected in terms of drive to an electric motor 34, which is connected to a central control unit 38 via a control and drive line 37.
  • the control unit 38 contains a changeover switch 44, which is connected to the main lamp 11 or replacement lamp 12 via feed lines 51, 52.
  • the changeover switch 44 is in such a position that it is supplied with power only via the feed line 51 to the main lamp 11. If the main lamp 11 burns out, the control unit 38 automatically switches the changeover switch 44 to its other position, where it supplies the replacement lamp 12 with power via the feed line 52.
  • a preferred implementation of the switch 44 is described below with reference to FIG. 10.
  • the control device 38 is supplied with the required voltage and power via a power supply 39 connected to the network.
  • a further rotating sleeve 24 is provided axially offset coaxially to the rotating sleeve 23 and independently of this, which belongs to a further rotating holder 16 for a replacement lamp 12.
  • a support arm 18, shown in dashed lines, extends from the rotating sleeve 24 to the base 31, indicated by dashed lines, of a replacement lamp 12, which lies on the same circular path as the main lamp 11 in relation to the axis of rotation 32.
  • the rotating sleeve 24 is rotatably supported by means of a bearing 40, which is only indicated schematically, and by means of a drive train 41, which may also contain a reduction gear, with an electric motor 35 connected, which is connected via a control and drive line 42 to the control device 38 in order to obtain the control and drive signals required when the main lamp 11 burns out.
  • the surgical light described works as follows: When the main lamp 11 burns out, the changeover switch 44 automatically switches on the replacement lamp 12. At the same time, the control unit 38 sets the electric motor 34 in motion via the control and drive line 37, which then rotates the main lamp swivel mount 15 in the direction of the arrow P in FIG. 2 until it reaches the position 15 ′ indicated by dotted lines in FIG. 2. has reached. As a result, the main lamp 11 moves from the desired point 13 located in the focus of the surgical light into a lamp change position 21.
  • the electric motor 34 is switched off by the control device 38, which can take place either on the basis of a time switch provided in the control device 38 or by means of a limit switch provided in the area of the stop 43.
  • the control unit 38 then switches on the electric motor 35 via the control and drive line 42, which now rotates the replacement lamp holder 16 in the direction of the arrow F in FIG. 2, as a result of which the replacement lamp 12 is pivoted from its waiting position 14 to the desired position 13. There, the control unit 38 stops the electric motor 35 either on the basis of a suitable time circuit provided in it or on the basis of a switching contact provided in the area of the set point 13, as a result of which the replacement lamp 12 is now positioned at the set point 13 and takes over the task of the main lamp 11.
  • the main lamp 11 After the main lamp 11 has been replaced in the lamp change position 21 with the lamp switched off, for example after an operation has ended, the main lamp 11 is returned to the desired point 13 as follows:
  • the control unit 38 automatically switches off the replacement lamp 12 or leaves it switched off due to the current flowing back to the main lamp 11.
  • the motors 34, 35 are successively driven so that the replacement lamp 12 is first pivoted back from the target position 13 to the waiting point 14, whereupon the main lamp 11 is then pivoted from the lamp changing position 21 to the target point 13.
  • the operating light is again in a fully operational state, that is to say that after the main lamp 11 has burned out again, the replacement lamp 12 is pivoted in its place, as was described above.
  • the main lamp holder 15 can be biased by a spring 19, which is only indicated schematically, in the direction of arrow P to a stop 20, which is connected to the rotary shaft of the electric motor 34 via an actuating arm 45, which is indicated by a broken line.
  • the rotating sleeves 23, 24 are in this case freely rotatable (that is, not directly driven by electric motors 34, 35) on a suitable stationary and non-rotatable shaft.
  • the fixation of the main lamp 11 at the desired point 13 and the replacement lamp 12 at the waiting point 14 is ensured by pressing the support arm 17 by means of the spring 19 against the stop 20 or by pressing the support arm 18 by means of a spring 46 against a machine-fixed stop 47.
  • the stop 20 moves in the direction of the arrow G in FIG. 2, as a result of which the spring 19 holds the holder 15 in the direction of the arrow P sets in motion until it abuts the stop 43 and the main lamp 11 has reached the lamp changing position 21. In this position, the bracket 15 is fixed by the spring 19 and the stop 43.
  • the stop 20 moves in a circular path about the axis of rotation 32 until it has reached the position designated 20 ′ in FIG. 2 and now acts on the support arm 18 in FIG. 2 from the right. Then the replacement lamp swivel bracket 16 with the already burning replacement lamp 12 in the direction of arrow F with compression of the spring 46 in motion until the replacement lamp 12 has reached the desired point 13, where it z. B. is stopped by a mechanical stop 55 acting only on the support arm 18. At this moment or shortly thereafter, the control unit 38 switches off the electric motor 34 on account of a built-in timer or on the basis of a position switch, whereupon the stop 20 stops and the replacement lamp 12 is now fixed at the desired point 13.
  • the two electric motors 34, 35 are arranged in a frame 48 one behind the other, which drive the rotating sleeves 23 and 24 via suitable gearwheels 49 and 50, respectively.
  • the electric motor 35 and the gear 50 are omitted, and the output shaft 27 of the gear 49 extends through a frame-fixed bearing into the interior of the rotating sleeve 23.
  • a stationary pivot pin 25 attached to the frame 38 extends coaxially with the rotary shaft 27 into the interior of the further rotary sleeve 24.
  • a radial stop 20 is attached to the end of the rotary shaft 27 facing the pivot pin 25, which extends radially beyond the outer circumference of the rotary shaft 27 and interacts with a counter stop 29 attached to the rotary sleeve 23.
  • the stop is shown once in an inactive position 20 ′ and once at 20 in contact with the counter stop 29, which is provided on the circumference of the rotating sleeve 23. 3 and 4, a counter-stop 28 provided on the rotary sleeve 24 extends axially into the path of the stop 20.
  • the rotary sleeve 24 ends in the direction of the stationary pivot pin 25 in front of the stop 20, so that it can move freely in the rotation of the rotary shaft 27 apart from the deliberate obstruction by the counter stops 28, 29.
  • the springs 19, 46 are designed according to FIG. 4 as coil springs which are supported on the one hand on the frame 48 and on the other hand in elongated holes 22, 26 of the support arms 17 and 18, respectively.
  • FIG. 4 The basic position of the positioning device according to the invention is shown in FIG. 4.
  • the stop 20 according to FIG. 4 moves counterclockwise, as a result of which the clock spring 19 can also rotate the support arm 27 counterclockwise until it abuts the stop 43 and remains in the position 17 'shown in broken lines .
  • the stop 20 then continues to rotate counterclockwise until it comes to rest against the counter stop 28 of the rotary sleeve 24 and the rotary sleeve 24 or Support arm 18 lifts against the force of the clock spring 46 from the stop 47 and now pivots the support arm 18 and the replacement lamp 12 into the position which had previously been assumed by the support arm 17 and the main lamp 11, ie brings it to the desired point 13.
  • the counterstop of the rotary sleeve 24 is preferably arranged at 28 'in FIG. 4, because then the stop 20 acts on the counterstop 28' immediately after the support arm 17 comes to rest against the stop 43, so that the swivel mount carrying the replacement lamp 12 16 begins to move to the position in which the replacement lamp 12 is located at the desired point 13 immediately after the pivot bracket 15 has come to a standstill.
  • the bases 30, 31 are rotated by 45 ° about the longitudinal axis of the support arms 17 and 18 compared to the arrangement according to FIG. 5 such that the lamp filaments 53 of the main lamp 11 and the replacement lamp indicated in FIG. 6 12 are still parallel to one another, but are arranged so as to be offset laterally that the light beams emanating from the lamp filaments 53 are not shadowed by the other lamp.
  • the formation of the swivel brackets 15, 16 must also be such that the centers of the lamp filaments 53 of both lamps 11, 12 lie one behind the other in the peripheral direction 54 determined by the pivoting movement, so that the lamp filaments 53 of both lamps 11, 12 are at their Assume the exact position at the set point 13.
  • FIG. 7 schematically shows a particularly preferred embodiment in which two swivel brackets 15, 16 of identical design are provided. Because the swivel brackets 15, 16 are formed symmetrically to that swivel plane 60 which runs through the center of the lamp filaments 53, identically designed swivel brackets 15, 16 can be attached one behind the other on the axis of rotation 32 by an arrangement offset by 180 ° with respect to the swivel plane 60, which then causes the lamp filaments 53 both the main lamp 11 and the replacement lamp 12 lie exactly in the pivot plane 60.
  • the two rotating sleeves 24 are arranged one behind the other on the axis of rotation 82, both lamp filaments 53 can nevertheless be located in the pivot plane 60 due to the arrangement offset by 180 ° relative to one another.
  • This embodiment is particularly economical because only one type of swivel bracket has to be produced and the rotary sleeves 23, 24 can nevertheless be arranged one behind the other on the same axis of rotation 82, which in turn is important for the possibility of driving with only a single motor.
  • FIG. 8 shows a structural implementation of the embodiment described with reference to FIG. 7.
  • the peculiarity compared to the preceding exemplary embodiments is that the rotary shaft 27 extends through both rotary sleeves 23, 24 and is rotatably supported in the frame 48 with both ends. In this way, no stationary pivot pin needs to be used for one of the rotating sleeves, as is provided for the rotating sleeve 24 in the exemplary embodiment according to FIG. 3.
  • the rotating shaft 27 passing through both rotating sleeves 23, 24 thus means a structural simplification and further enables a particularly compact and economically producible arrangement of the stop 20 and the counter-stops 28, 29, as is also described below on the basis of FIG. 9, which is the Interaction of the stop 20 with the counter-stops 28, 29 is illustrated schematically.
  • the radially projecting stop 20 is again provided, which has the shape of a pin.
  • the rotating sleeves 23, 24 have sector cutouts 55, 56 on their adjoining end faces, which, however, can have different extensions in the circumferential direction depending on their function.
  • the rotary sleeve 23 in FIG. 9 is illustrated in solid lines and the axially offset rotary sleeve 24 is shown by broken lines.
  • the rotating shaft 27 passing through both rotating sleeves 23, 24 is also shown in solid lines.
  • the motor 34 is not set in motion by this, it or its transmission must be designed to be self-locking.
  • a geared motor with a gear ratio of z. B. 1: 140 is used.
  • the geared motor is arranged horizontally in such a way that the gearwheels are always immersed with a part of their circumference in the oil bath in the gearbox even in the idle state.
  • all areas of each gear wheel of the gearbox are supplied with oil after just one revolution.
  • Such an arrangement is in the present operating light important because the main lamp 11 of an operating light burns out only relatively rarely and the geared motor is therefore only rarely started up accordingly.
  • the engine is strongly heated by the burning lamp 11 or 12, so that the gear oil collects in the lower area.
  • the motor 34 is switched on, so that it begins to drive the rotary shaft 27 in the direction of the arrow in FIG. 9 via the gear 50.
  • the stop 20 in FIG. 9 then moves freely counterclockwise within the sector cutout 57 of the rotary sleeve 24, which is initially held in its waiting position by the spring 46.
  • the spring 19 maintains the abutment of the counter stop 29 against the stop 20 by pivoting the swivel bracket 15 counterclockwise in FIG. 9. In this way, the counter-stop 29 initially remains in contact with the stop 20.
  • the swivel mount 15 follows the movement of the stop 20 due to the action of the spring 19.
  • the rotary shaft 27 continues to rotate in the direction of the part shown in solid lines (FIG. 9).
  • the sector cutout 57 of the rotating sleeve 24 is now dimensioned in the circumferential direction in such a way that, in the view according to FIG. 9, it ends counterclockwise immediately behind the lamp change position 21, so that the stop 20 finally hits against the through the left end of the sector cutout 57 formed abutment 28 of the rotating sleeve 24 and this now rotates against the force of the spring 46. So that the rotation of the stop 20 does not come into contact with the end 61 of the sector cutout 56 which is present in the counterclockwise direction in FIG. 9, the sector cutout 56 must have a correspondingly long circumferential direction.
  • the pivoting movement of the stop 20 in contact with the counter-stop 28 now continues until the pivot holder 16 is in the desired position which was initially assumed by the pivot holder 15 (FIGS. 8, 9).
  • This position can be defined by a suitable stop (55 in FIG. 2) for the swivel bracket 16.
  • the geared motor 34 is stopped either by a limit switch connected to the stop or, preferably, by a timing element which allows the motor to run somewhat longer than is necessary to reach the stop 55 defining the desired position. In this case, the drive power supplied to the geared motor 34 must be so low that the motor does not suffer any damage when the swivel holder 16 is struck against the stop 55 despite the supply of drive current which then continues for a short time.
  • the rotary shaft 27 is rotated in the direction indicated by a dashed arrow in FIG. 9, the pivot holder 16 first being moved clockwise by the spring 46 until it rests against the stop 47 . Then the stop 20 then detects the swivel bracket 15 by coming into contact with the counter stop 29. Now the rotary shaft 27 pivots the swivel bracket 15 from the lamp change position 21 against the spring 19 into the target position shown in FIG. 9, where the swivel bracket 15 again by a suitable stop (60 in FIG. 2), optionally with a limit switch for Is brought to a standstill.
  • the geared motor 34 can be switched by a timing element in such a way that it continues to be supplied with current for a short time after the pivot bracket 15 has been struck at the stop 55 and only then switches off.
  • both the extension and the retraction of the main or replacement lamp can be accomplished in this way with a single motor which can be reversed in opposite directions of rotation.
  • FIG. 10 shows purely schematically one possibility of how the lamps 11, 12 and the geared motor 34 which can be reversed in two directions of rotation can be supplied with current.
  • a power supply unit 39 supplies the control unit 38 with a voltage suitable for supplying the lamps 11, 12.
  • the current for the main lamp 11 flows through a relay 62 which picks up due to this current flow and holds the changeover switch 44 connected to it in the open position.
  • the replacement lamp 12 is connected via the switch 44 to the voltage supplied by the power supply 39.
  • the current flow through the relay 62 stops and the changeover switch 44 is moved, for example by a spring, into the rest position shown in dashed lines in FIG. 10, in which the replacement lamp 12 is now connected to the supply voltage.
  • the replacement lamp 12 is therefore switched on automatically.
  • the relay 62 also has two further changeover contacts 63, 64, which are acted upon, for example, by a DC voltage and in the switching position shown in FIG. 10, in which the relay 62 is traversed by current, supply the motor 34 with a direct current 59 via a timer 59 and a feed line 58 in such a way that it is driven in the direction of rotation in which the rotary shaft 27 is shown in FIG. 9 by a dashed arrow indicated direction rotates, whereby the pivot bracket 16 is pivoted into the waiting position and the pivot bracket 15 in the desired position.
  • the timer 59 is designed so that it automatically switches off the motor 34 when the time it takes for the swivel brackets 15, 16 to move to the position shown in FIG. 9 has expired with certainty.
  • the geared motor 34 is set in rotation so that the rotary shaft 27 begins to rotate in the direction indicated in FIG. 1 by a solid arrow.
  • the timer 59 also ensures in this case that the geared motor 34 only remains switched on until the swivel bracket 15 has safely reached the lamp changing position 21 and the swivel bracket 16 has reached the desired position in which the replacement lamp 12 is located at the desired position 13.
  • a major advantage of the present invention is therefore that by switching immediately from the Main lamp 11 on the replacement lamp 12 when the main lamp 11 burns out is reliably avoided that there is brief darkness in the operating room. Since the gear motor 34 is also started when the main lamp 11 burns out, it is further ensured that the main lamp 11 is immediately removed from the desired position and the replacement lamp 12 is brought into this position.
  • the spring 19 relieves the geared motor 34, so that the main lamp 11 moves out of the desired position much faster than the replacement lamp 12, where the motor 34 is moved in must work against the spring 46.
  • the replacement lamp 12 is slower, i. H. Carefully moved into the desired position, while the burnt-out main lamp 11 can be transferred to the lamp changing position 21 much faster, which is therefore not a disadvantage, but rather advantageous because the main lamp 11 is burned out anyway and further damage caused by those to be expected with rapid movement Vibrations no longer matter.
