Definitions

  • the present invention relates to a control unit for a medical lamp, in particular for a surgical lamp or examination lamp, with at least one control element for adjusting the size of a generated by the lamp at a predetermined location light field, an electronic interface for outputting control signals for the size of the light field to a control device of the luminaire and a screen for displaying the currently set size of the light field.
  • the light field size of a medical lamp must be adapted to the respective situation during each operation or examination.
  • knowledge of the currently set light field size is advantageous, e.g. be able to estimate the remaining margin of freedom up or down.
  • a lighting system is disclosed with a plurality of controllable individual light sources.
  • Single light sources such as brightness and color temperature are adjustable by means of a radio remote control unit.
  • specific light data are detected in a position-dependent manner by means of a detector integrated in a portable device.
  • the US 2011/0245939 A1 discloses a system for demonstrating various illumination patterns based on an array of mobile light towers.
  • the light poles can be controlled by a portable computer to vary the beam angle or light intensity.
  • the operating unit is designed to reproduce a model representation of at least one lamp body of the lamp including a light cone emanating from the lamp body on the screen during operation of the lamp and in adjusting the size of the light field by means of the control element, the shape of the light cone in the representation to change.
  • the screen thus serves, on the one hand, to directly display the light field size and is additionally used to model the lamp body and graphically follow the light field adjustments made by an operator in this illustration. Due to the changing of the light cone screen display in synchronism with the light field adjustment, an operator can capture the current light field size much faster and more intuitively than is possible exclusively by means of numerical value or scale displays. In particular, it is possible to quickly and easily determine at which point in the range of possible light field sizes is the current setting. The operator is thus distracted to a lesser extent from the actual operation or investigation task, which is particularly important in difficult medical activities of great importance.
  • the operating unit is designed to change the shape of the light cone in the representation in real time during each adjustment process. This facilitates the operation of the lamp in particular. For example, Adjustments of the light field size can be made under observation of the representation on a trial basis.
  • the representation of the luminaire body and the light cone fills at least 40%, preferably at least 50% and particularly preferably at least 70% of the total visible height and / or the entire visible width of the screen.
  • the largest possible representation of the luminaire body and the light cone on the available screen surface ensures good visibility. In particular, an operator can easily recognize a large format image even from a distance away from the control unit and under stress conditions.
  • a purely symbolic representation e.g. In the form of an "icon"
  • a larger image on the screen gives a realistic and quickly comprehensible impression of the state of the "real" light cone of the luminaire.
  • the representation of the lamp body and the light cone may be in particular perspective. This further enhances the recognizability of the display and contributes to an improved assessment of the light field size on the basis of the screen display.
  • a light field can additionally be reproduced, wherein the operating unit is designed to correspondingly change the size of the light field in the representation when the size of the light field is adjusted by means of the operating element.
  • An embodiment of the invention provides that the screen is touch-sensitive and the operating element is integrated in the screen.
  • the screen can be designed as a touchscreen.
  • the control element can be combined in this embodiment with the representation of the lamp body and the light cone.
  • the operating element can be superimposed on the illustration of the luminaire body and the light cone.
  • the representation may thus be e.g. extend as a background image over a substantial part of the screen surface, while a control panel forming the touch screen is arranged in the foreground. This offers the advantage of a favorable utilization of the available screen area.
  • the operating unit can also comprise an operating element for adjusting the brightness of a light source of the luminaire, wherein the operating unit is designed to correspondingly change the brightness of the light cone in the display on the screen when the brightness of the light source is adjusted. For an operator, it may in fact be much easier to reconstruct a change in brightness on the light cone shown than in the real operation or examination field.
  • the operating unit may comprise an operating element for adjusting the color temperature of a light source of the luminaire, wherein the operating unit is designed to adjust the color tone of the light cone in the illustration on the screen when the color temperature of the light source is adjusted Screen change. Since the color temperature of a light source can be correlated with the color tones that can be displayed on a screen, this embodiment also enables an operator to quickly and intuitively detect the color temperature influence by the operating unit.
  • an increase in color temperature from a minimum value to a maximum value is correlated with a change in hue of the light cone in the on-screen representation from orange to yellow to white.
  • a color temperature of the light source of 4500 K in the representation of the light cone corresponds to a white hue.
  • An operator can then detect and assess color temperature changes particularly quickly because low color temperatures are usually associated with reddish hues and higher color temperatures with white or bluish color temperatures.
  • Daylight has a color temperature of approximately 4500 K.
  • the color impression of the light source corresponding to the set color temperature can be generated as accurately as possible taking into account the display options of the respective display elements on the screen.
  • a further embodiment provides that a separate control element is provided for adjusting the size of a light field generated by the luminaire at a predetermined location, the brightness of a light source of the luminaire and the color temperature of the light source. This allows a comprehensive control of the lamp under control of the display of the lamp body and the light cone on the screen.
  • the operating unit may further comprise an operating element, upon actuation of which an image of different sizes is displayed on the screen, in particular an image of an operating field or examination field generated by a camera.
  • an operating element upon actuation of which an image of different sizes is displayed on the screen, in particular an image of an operating field or examination field generated by a camera.
  • Such integrated in the screen "zoom function" can provide an operator improved visibility. For example, a site of interest of the surgical field may be viewed at a desired magnification on the screen.
  • a switching element may be provided, upon actuation of which the screen image of the lamp body and of the light cone is hidden and instead the camera image is displayed. For the camera image is then a larger screen area available.
  • the switching element can also be used to switch back to the representation of the lamp body and the light cone.
  • a light exit surface of the lamp body can also be reproduced, which in particular has the same color as a light field reproduced in the illustration. This allows an operator to further find and capture the representation.
  • a control unit 10 for a surgical light comprises a screen 12 designed as a touch screen, which is preferably based on a liquid crystal display or plasma display and which is accommodated in a housing 14.
  • the housing 14 may be designed for the articulated attachment to a component of the operating light or for wall mounting.
  • the screen 12 is about 95 mm wide and about 55 mm high and has a central region 16 and two lateral regions 17, 18.
  • a plurality of lateral control elements 19 are arranged, by means of which the operating light is switched on and off and various additional functions such as a camera image display can be activated.
  • three central operating elements 20A, 20B, 20C are arranged, which serve to control lighting parameters of the operating light.
  • An electronic interface, not shown, of the operating unit 10 communicates with a plurality of actuating and control devices of the operating light and ensures that each adjustment made by the operating elements 19, 20 is implemented by outputting corresponding control signals directly into the associated change in illumination of the operating light.
  • the control unit 10 also includes a video interface (not shown) configured to receive a video signal from an electronic camera.
  • the electronic camera can be integrated into the surgical light and transmit an image of the surgical field.
  • Fig. 1 the background in the central area 16 of the screen 12 is a luminous representation 22 which fills about 90% of the height of the screen 12 and in perspective form a lamp body 24 of the operating light including a handle 26 obliquely from below and one of the lamp body 24 outgoing Light cone 28 shows. Also, the light field 30 generated by the surgical light at the predetermined surgical field and the light exit surface 32 of the lamp body 24 is shown in the light display 22.
  • the three central operating elements 20A, 20B, 20C are superimposed on the luminous display 22 and arranged in the foreground of the central area 16 of the screen 12.
  • the luminous display 22 reproduces the state of the light cone 28 realistically, taking into account the current settings of the operating elements 19, 20.
  • the operating unit 10 is further configured to dynamically adjust the lighting display 22 in real time during operation of the operating light, as further described below with reference to FIGS Fig. 2-5 is explained in more detail.
  • the brightness of the light cone 28 in the light display 22 is changed when an operator of the operation light operates the middle operation member 20B provided for adjusting the brightness of a light source of the operation light.
  • an operator may start from a maximum brightness according to Fig. 1 choose a minimum brightness by means of the middle control element 20B. It will then according to Fig. 4 in the light display 22 a opposite Fig. 1 darker light cone 28, a darker light field 30 and a darker light exit surface 32 are shown.
  • the color tone of the light cone 28 in the light representation 22 is changed in an analogous manner as in an adjustment of the light field size and the brightness.
  • an operator may start from a color temperature of 4500K according to Fig. 1 select a color temperature of 3600 K by means of the upper control element 20C. It will then according to Fig. 5 in the light display 22 a light cone 28, a light field 30 and a light exit surface 32 in one opposite Fig. 1 reddish hue shown.
  • the upper control 20C allows switching between four different color temperature values.
  • the value 3600 K is an orange hue
  • the value 4000 K a yellow hue
  • the adjustment of the size of the light field, the brightness and the color temperature is possible independently, with the light display 22 is adjusted in each case in real time to the changed setting. For example, for example, when the brightness of the light source is increased by means of the operating element 20B, the light cone 28 is displayed brighter, even if the light field size remains unchanged.
  • the operator of the operating light can detect the current lighting condition much faster than if, for example, only among the three superposed controls 20A, 20B, 20C would have to pick out the desired item to check the switch or slider position on it.
