Definitions

  • the invention relates to an operating light with a light bulb having a lamp bulb and a reflector system assigned to the light source with areas which reflect visible light and absorb or transmit infrared radiation, the lamp bulb, which is in part designed as a cylinder jacket, having a region which is transparent to infrared radiation; Furthermore, the invention relates to an operating light designed in this way, which has a deflecting mirror which, with its mirror surface, faces the regions of the reflector system which absorb or transmit infrared radiation.
  • incandescent halogen lamps in various types of optical systems, such as studio and operating lights, or daylight projectors for foils, with the smallest possible proportion of infrared light emerging in the direction of radiation in order to reduce the heat radiation in the lighting field. This is usually done by reflectors which transmit infrared light and reflect the visible light and / or by filters at the light exit openings, which largely absorb the infrared light component.
  • a dental surgical light is known with a concave reflector as part of an ellipsoid of revolution, in the middle of which an incandescent lamp is arranged, the filament of which is located in the focal point of the main reflector provided with a plurality of concave or convex grooves .
  • the incandescent lamp has a reflective coating on its side facing away from the reflector, which prevents direct radiation to the patient and supplies the radiation to the main reflector.
  • the coating of the main reflector can also be embodied as a coating that transmits infrared radiation, so that the incandescent lamp is located in a so-called cold light reflector.
  • a cylindrical halogen incandescent lamp is known with an electrical connection at each cylinder end and with an incandescent filament guided along the cylinder axis of the lamp bulb, the lamp bulb of which is coated on the outside with a multilayer body which acts as an interference filter and which contains the infrared components of the the lamp generated light reflects on the filament, while it transmits the visible portions of the generated light.
  • End reflectors are provided at the ends of the filament, which have an optical coating reflecting all emitted radiation components.
  • the interference filter has layers with alternating high and low refractive indices, the materials of these layers consisting essentially of silicon dioxide and tantalum pentoxide.
  • interference filters Another application of interference filters is known from DE-GM 18 09 322, in which a cold light mirror that is permeable to heat rays is described, the surface of which is alternately higher and higher with a series of interfering dielectric layers low-index substances are covered; Silicon oxide and titanium oxide or tantalum oxide are used as layer materials.
  • an incandescent lamp with a quartz glass bulb which is coated with an optical interference filter film so that the visible light is transmitted and the infrared radiation is reflected onto the incandescent filament for the purpose of increasing the efficiency.
  • the lamp bulb thus has a region which is only permeable to visible light, namely the coated region, and a region which is transparent to infrared radiation, namely the region of the sealing section in which no interference filter is applied.
  • the object of the invention is to achieve the simplest possible infrared light output from the illumination field by geometrically assigning the light source and reflector and by partially coating the outer bulb surface of the light source, the lamp and reflector being relatively inexpensive despite their optimal effectiveness.
  • the object is achieved by the characterizing features of claim 1 and for an operating room lamp with a deflecting mirror by the characterizing features of claim 2.
  • it is an operating light with a light source having a lamp bulb and a reflector system assigned to the light source with areas which absorb or transmit infrared radiation, an interference filter consisting of several layers being applied to the outer surface of the lamp bulb, which has a high Has transparency for visible light and a high reflectivity for infrared light, wherein the lamp bulb has a region permeable to infrared radiation, and wherein the lamp bulb is oriented within the reflector system in such a way that the for Infrared radiation permeable area of the lamp bulb is assigned to the areas of the reflector system that absorb or transmit infrared radiation.
  • an operation lamp with a light bulb having a lamp bulb and a reflector system assigned to the light source with areas which absorb or transmit infrared radiation, an interference filter consisting of several layers being applied to the outer surface of the lamp bulb, which has a high Has transparency for visible light and a high reflectivity for infrared light and with a deflecting mirror, whose mirror surface faces the infrared radiation absorbing or transmitting region of the reflector system, the lamp bulb having a region permeable to infrared radiation, and wherein the lamp bulb is oriented within the reflector system and the deflecting mirror in such a way that the region of the lamp bulb which is permeable to infrared radiation is assigned to the deflecting mirror which absorbed the infrared radiation and which absorbed the infrared radiation feeding or transmitting area of the reflector system.
  • FIG. 1a shows a halogen incandescent lamp according to the invention in longitudinal section, while a longitudinal section through an operating light is shown in FIG. 1b.
  • the visible light shining through the interference filter 3 reaches the reflector 7 partly directly, partly via the deflecting mirror 12, from which it is reflected into the actual illumination field; the infrared radiation, however, emerges through the uncoated base area 5 of the lamp bulb 1; it is led out of the optical system via the opening 8 in the reflector system 11 or the part of the reflector system 11 which transmits infrared light, and reaches heat-absorbing bodies directly or indirectly, which are not shown in FIG. 1b for a better overview; When the heat-absorbing bodies are indirectly irradiated, the infrared light is directed to the heat-absorbing bodies via deflecting mirrors. It is of course also possible to arrange the lamp bulb by rotating it through 180 ° such that the area 4 of the dome of the lamp bulb 1 is adjacent to the opening 8 in the reflector system 11 or the part transmitting infrared light.
  • the optical system surrounding the lamp is designed in such a way that only the filament of the lamp is imaged in the light field, the light field is almost free of annoying heat radiation.
