the invention relates to a lamp body for a medical lamp, in particular an operating lamp, with at least two electric lamps, one of which is in normal operation with their version of a predetermined centering position in the fixed part of the lamp body is assigned while a second lamp with its socket is in a reserve position is located outside the centering position, the sockets if the first lamp fails both lamps in their position by an electromagnetically operated swivel device are changeable so that the second lamp is in the centering position for reserve lamp operation can be swiveled in after the first lamp has been withdrawn from the centering position is; Furthermore, the invention relates to the use of such a lamp body directed.
a lighting device with two alternately operated electrical units is used as the luminaire body Designated lamps, as is known for example from DE 200 04 384 U1; on such luminaire body is in the center or in the focus of a reflector surrounding it, preferably ring reflector, the reflector and luminaire body being a common one Form unit as a medical light or operating light, using a bracket is rotatably and pivotally attached.
an operating light is known from EP 0 730 120 A1 and DE 195 07 305, the at least one main lamp arranged at a target location and one close to it Has replacement lamp located in a waiting area.
the main lamp and the spare lamp are held and controlled in such an adjustable manner that when the main lamp burns out this moves away from the target point and the replacement lamp from the waiting point to the target point moved and held there.
the main lamp and the spare lamp are independent on mounts movable from each other attached.
a fail-safe lamp in particular lamp for known medical arrangements, which contains at least one discharge lamp, wherein the lamp has a supply unit connected to a power supply system with a additional safety power supply by switching to a backup power source in the In the event of a malfunction.
the supply unit has a buffer memory, the energy supply for the operation of the discharge lamp during a fault the switchover to the backup power source.
the object of the invention is to provide a medical lamp with a main and reserve lamp create, in which one of the two lamps is designed as a discharge lamp, while the Reserve lamp in its design or power not easily equivalent to a discharge lamp is.
An optimal centering position in the reflector area should be in reserve lamp operation be taken up by the reserve lamp.
the first lamp is based on two sides
Discharge lamp is formed with axially opposite connection contacts, the one end together with a second lamp in the form of an incandescent lamp first version is held and contacted, which together with a second, at a distance arranged socket for holding and contacting the other end of the discharge lamp is formed as part of a pivoting device rotatable about an axis, whereby by an unlocking process a rotation of the pivoting device with the help of a Swiveling device and stationary part of the lamp preloaded torsion spring can be triggered is.
the rotation of the swivel device is preferably by means of an electromagnetic release one with a form-fitting locking pin engaging in one of the sockets the fixed part of the lamp mechanically and electrically connected locking device triggered.
the torsion spring required to carry out the pivoting movement engages on one Eccentric point of the swivel device with respect to the axis of rotation of the swivel device on.
one of the two sockets has at least one recess provided for positive connection by snapping the locking pin, this counter to the stroke direction of the locking device by means of a preloaded spring is under mechanical tension.
the locking pin is advantageously when the locking device is magnetically excited completely removed from the recess of the socket.
the socket has a slant in the area for the recess for the locking pin shaped surface for easy sliding of the locking pin until it is lowered into the Recess on.
the opposite connection contacts of the discharge lamp operated as the first lamp are arranged along an axis that is parallel to the axis of the pivoting device.
the lamp body is inserted into a ring lamp, which has a ring reflector arranged at a distance from the lamp body, so that due to natural convection an optimal dissipation of the generated radiant heat is possible.
Figure 1 shows the lamp body according to the invention without an outer housing with the first Discharge lamp provided in its centering position.
FIG. 2 shows the second lamp provided with a filament in the centering position, as shown in FIG Failure of the first lamp (discharge lamp) is taken.
FIG. 3 shows an operating light with the light body according to the invention used, which is surrounded by a ring reflector.
Luminaire body has a fixed or fixed socket 2 and movable sockets 1 and 15, which as part of a pivoting device 16 about a pivot axis - here schematically entered pivot axis 17 - is rotatably mounted.
the two versions 1 and 15 together with the connecting rods 18 and 19 form the movable core of the Swivel device 16.
Discharge lamp serving as main lamp and used on two sides is used as first lamp 3, which is according to Figure 1 in its centering position (with respect to the reflector).
the second lamp 4 (reserve lamp) recognizable, which is based on one side and thus on the movable first version 1 is attached.
the area of the movable holder 1 is to trigger the pivoting process required prestressed torsion spring 8 recognizable, which as a coil spring is formed, which encompasses a rod not visible here. It is in normal operation in the prestressed state, with one end of the torsion spring 8 on the fixed Version 2 is attached, while the other end at an eccentric point of the Swiveling device 16 attacks.
the first lamp 3 is in the centering position, whereby at the same time the locking pin 6 positively engages in a recess 10 of socket 1; the locking pin 6 is countered by means of a helical spring (compression spring) a lifting magnet 5 supported above.
a helical spring compression spring
a part of the fixed version is also located above the movable version 1 2, which is additionally connected to an igniter 7 for the first lamp (discharge lamp) is; thus is in the fixed version 2 of Figure 1 above the movable version 1 the igniter 7 can be recognized for the discharge lamp functioning as the first lamp, the electrical connections, which also serve to supply the lamps, with the reference numerals 20, 21 are designated.
the compression spring 9 is in FIG the solenoid 5 can be seen, which a permanent pressure without external force exerts on locking pin 6, so that it in its rest position in the recess 10 engages positively and thus prevents movement of the pivoting device 16.
the first lamp 3 discharge lamp
a sensor (not shown here) is used the pressure magnet 5 of the locking device controlled, this the bias of Compression spring 9 dubbed and thus the positive lowering of the locking pin 6 the recess 10 of version 1 is released so that after the opening of the recess 10 force exerted by the torsion spring 8 on the swivel device 16 is effective and the second lamp 4 as a reserve light bulb enters the centering position of the first lamp 3 while Lamp 3 is removed from the centering position at the same time.
the pivoting device 16 After the end of any lamp operation with the second lamp 4 as a spare lamp the pivoting device 16 is returned to its starting position by manual actuation brought back so that the main illuminant 3 is again in the centering position. It is then checked and replaced if necessary, so that it can be put back into operation of the lamp body is possible without further problems. With increased security requirements, As with surgical lights, the one used as a reserve light source is also used at the same time second lamp 4 checked and, if necessary, replaced to ensure a high level of failure security for further To maintain light periods.
FIG. 2 shows the basic element of the lamp body with the second lamp 4 in the centering position, so that after the first lamp 3 (main illuminant) fails, operation continues is possible.
locking pin 6 now is located outside the not recognizable recess 10 of the movable holder 1, so that the lower edge of the locking pin 6 on the barely recognizable slope 12 of Version 1 (see Figure 1) burdens.
the medical lamp surgical lamp
the second lamp 4 is then the second lamp 4 from the rotation of the pivoting device 16 Centered position brought out, the lamp 3 for normal operation now in its starting position device in which it can also be exchanged in a simple manner.
the lamp body 23 is located in the center 25 of one Operating lamp 24, the outer periphery of the housing of lamp body 23 System of ring lenses 26, as known for example from DE 200 04 384 U1 are.
