Definitions

  • the invention relates to an operating light with at least one on and switchable discharge lamp according to the preamble of the claims 1 and 3.
  • the aim of the invention is to provide an operating light at the beginning to create said genus, in which without the need for additional Incandescent lamps can be used to control brightness in the operating field is.
  • the idea of the invention can therefore be seen in the fact that the brightness control in the operating field is done by either two or more Discharge lamps of different wattages can be switched on. On in this way it is not possible to adjust the brightness continuously, but gradually in the operating field, which is full for practical purposes is sufficient.
  • Another object of the invention is in the event of failure of the currently burning Discharge lamp on for continued operation full to provide usable reserve light.
  • a suitable spare light is provided by a discharge lamp. Changes itself in this embodiment in the event of the replacement of a failed one Discharge lamp by another one in the same housing the illuminance in the operating field, but stands on everyone If there is still enough light available to illuminate a corridor To complete the operation. In this case too, are after the failure a discharge lamp all of those in the lamp body Replace discharge lamps.
  • the plurality of discharge lamps can be stationary according to claim 6 or adjustable according to claim 7 in a common reflector his.
  • An indicator must be provided on the luminaire to indicate the failure of a discharge lamp signals, whereupon all in the luminaire body Discharge lamps are to be replaced by new ones. In this way is an absolutely fail-safe operation of the lamp even in the event of Failure of a discharge lamp ensured without the quality of the Illumination of the surgical field is impaired.
  • a reflector 13 is housed within a lamp body 20, completed by a translucent disc 21 below is.
  • a lamp adjustment device which as a lamp pivoting device or - as shown in Figure 1 - Can be designed as a lamp slide 22, arranged on the are in the distance discharge lamps 11, 15, one of which (11) is in the optical center (focus) of the reflector 13 while the second discharge lamp 15 is outside, e.g. sideways or located below the focus.
  • Each of the discharge lamps 11, 15 has its own ignition line 23 or 24 connected to an individual ignitor 12 or 16, which can be optionally switched on by a switching arrangement 15.
  • the discharge lamps 11, 15 are not in detail shown way on a controlled switchable high voltage supply on.
  • the carriage 22 is from the position shown in Figure 1, where the Discharge lamp 11 is located in the focus of the reflector 13 in a Position 22 'shown in dashed lines is displaceable or pivotable where the discharge lamp 15 is in a focal point of the reflector 13 lying position 15 'while the discharge lamp from the Focus is shifted out to position 11 '.
  • the switching arrangement 15 controls via a low-voltage control line 26 the displacement of the carriage 22 in synchronism with the changeover one or the other igniter 12, 16 such that when the Slide in the position shown in solid lines in Figure 1 is the ignitor 12 and the associated power supply put the discharge lamp 11 into operation while the outside discharge lamp 15 located at the focal point is switched off.
  • the operating voltage is simultaneously switched off by the discharge lamp 11 and also the ignitor 12 is put out of operation.
  • the operating voltage is applied to the Discharge lamp 15 applied and the igniter 16 activated. Prefers this happens so that the ignition of the discharge lamp 15 already before the switching of the carriage 22 has been completed, that after completion of the displacement or pivoting of the carriage 22 the discharge lamp 15 has already reached its full luminosity.
  • the lamps are usually powered by a power supply connected to the mains by a main switch 27 17, which e.g. provides an operating voltage of 24 V.
  • the microprocessor 19 switches the emergency power switch 28 at the moment and definitely within a few as a time of 1 sec to a battery emergency power supply 18 um, which supplies the same voltage as the power supply 17 at its output.
  • the discharge lamp 11 is located in the focal point of the reflector 13, sets from Microprocessor-controlled switching arrangement 25 the discharge lamp 11 to the operating high voltage and also ensures ignition via the ignitor 12 at the start of operation.
  • the discharge lamp 11 has an output of 35 W, for example the discharge lamp 15 can have a power of 70 W.
  • the light of the discharge lamp 11 is in the usual way via the reflector 13 through the disc 21 to one below the lamp body 20 located operating field 14 steered, which if possible is evenly illuminated.
  • the switching arrangement 25 first the discharge lamp 15 having the higher light output ignited via the ignitor 16 and at the same time the displacement of the Carriage 22 triggered in the dashed position of Figure 1. As soon as the carriage 22 has reached the new end position, the ignition process is in the discharge lamp 15 ended so that instead of the now turned off Discharge lamp 11 the discharge lamp in full operation 15 is located in the focus of the reflector 13. The result is a doubling the light intensity in the operating field 14, without the Illumination has changed something.
  • the emergency power supply 18 feeds the discharge lamps 11, 15 or the ignitors 12, 16 and the switching mechanism for the Sled 22.
  • the discharge lamps 11, 15 can also have the same power, each time the lamp is switched on, a change in the Turning on the discharge lamps 11, 15 occurs such that both Discharge lamps 11, 15 approximately the same number for illuminating the operating field 14 can be used. The result is a doubling of the Life of the overall discharge lamp assembly.
  • the control device in particular the microprocessor 19, can also do so be programmed to face the impending failure of a Operating charge lamp 12 or 15 detects. In this case, solve he automatically switches over to the other discharge lamp 15 or 11, so that in general none at all and at most one by Ignition time determined slight interruption in the lighting of the operating field 14 occurs, but at the latest after the ignition time of the new switched on discharge lamp, the operating field 14 again properly is illuminated.
  • Both the power supply 17 and the emergency power supply are advantageous 18 built into the lamp body.
  • the ignitors 12, 16 should as close as possible to the discharge lamps 11, 15, to reduce EM radiation.
  • the number of ignition processes should be registered in order to timely one To be able to change the discharge lamps.
  • a lamp replacement e.g. after 20,000 ignitions or 5000 operating hours respectively.
  • the power supply control integrated in the microprocessor 19 determines the technical condition of the discharge lamp by monitoring whether it is has given thermal or electrical overloads.
  • the microprocessor-controlled power supply 17 is used to operate at least two discharge lamps in parallel standby mode.
  • the power supply 17 takes over all functions of the electronic ballast and controls the required igniter 12, 16 and the correct one Lamp 11 or 15 on.
  • the discharge lamps 11, 15 could also be outside of the luminaire body, where then the light via light guide or Mirror is directed into the lamp body.
