Definitions

the invention relates to a lighting arrangement with a light bulb provided with a lamp bulb and with a reflector assigned to the light source, an interference filter consisting of several layers being applied to at least part of the outer surface of the lamp bulb, which has a high permeability for visible light and a high reflectivity for Has infrared light.
halogen incandescent lamps in various types of optical systems, such as studio and surgical 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 cylindrical halogen incandescent lamp with a filament guided along the cylinder axis of the lamp bulb is known, the lamp bulb of which is coated on the outside with a multilayer body acting as an interference filter, which contains the infrared components of the light generated in the lamp reflects on the filament while it transmits the visible portions of the generated light.
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 covered with a series of interfering dielectric layers made of alternately higher and lower refractive substances; Silicon oxide and titanium oxide or tantalum oxide are used as layer materials.
the object of the invention is to achieve the simplest possible infrared light shielding of 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.
a preferred embodiment is a halogen incandescent lamp with a base on one side, which is coated in such a way that infrared radiation emerges in the base region or in the dome region of the lamp bulb or in both regions.
FIG. 1a shows a halogen incandescent lamp according to the invention in longitudinal section
FIG. 1b shows a longitudinal section through an operating light
the halogen incandescent lamp with a base on one side has a cylinder-symmetrical lamp bulb 1, the side walls 2 of which are provided with an interference layer 3 in the cylinder jacket region.
the interference layer has layers with alternating high and low refractive indices, the infrared components of the light generated in the lamp being reflected into the interior of the lamp bulb.
the coating known from DE-OS 32 27 096 can be used as the interference layer; outside the actual cylinder jacket area, i.e. in the area of the dome 4 of the bulb or in the base area 5, the bulb is without an interference layer and thus transparent to infrared light.
the infrared radiation generated in the lamp or reflected by the interference layer in the bulb emerges at a defined solid angle ⁇ along the cylinder axis 6 of the lamp bulb 1.
the solid angle ⁇ is in the range from 20 to 160 °.
the visible light radiating through the interference layer 3 reaches the reflector 7 partly directly, partly via deflection 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; in the case of indirect radiation of the heat-absorbing bodies, the infrared light is guided to the heat-absorbing bodies via deflection mirrors. It is of course also possible to arrange the lamp bulb by rotating it through 180 ° such that the area of the dome 4 of the lamp bulb 1 is adjacent to the opening 8 located in the reflector system 11 or the part transmitting infrared light.
the lamp according to the invention thus provides a spatial separation of the exit directions from visible light and infrared radiation.
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.
the exemplary embodiment is explained using a halogen incandescent lamp; However, it is also possible to use a gas discharge lamp with a lamp bulb instead of the halogen incandescent lamp, the outer surface of which is provided with an interference filter which surrounds the discharge path of the lamp.
