Definitions

the invention relates to a medical lamp with at least one lamp and one Reflector composite radiator unit, the reflector made of metal and has a metallic or metallized surface, an opening with a circumferential, tubular flange for using at least one lamp with an opening cross-section adapted lamp base is provided and the base at least partially abuts the inside of the ring flange and at the end facing away from the light exit side the lamp of the base has an extended area which is at least partially on the The outer edge of the area of the ring flange facing away from the light exit rests.
the incandescent lamp is provided with a base which has substantially axially parallel guide surfaces; the guide surfaces of the base match the corresponding guide surfaces of the reflector immediately together; the base edge is provided with a stop surface, the distance up to the light center of the incandescent lamp is just as large as the distance between the assigned ones Stop surface of the reflector up to the reflector focal point; this will get the light bulb with its center of gravity automatically when pushed into the focal point of the reflector.
the reflector neck opening in the shape of a has a truncated cone that extends outwards.
the lamp base has one in the opening suitable conical surface on and on its side facing away from the reflector, it contains a groove for a clamp with which the base is detachably fastened in the reflector neck.
the socketed one Halogen light bulb is exchangeably attached to a plate by means of the clamping bracket.
From DE-B 10 61 900 is also a device for holding a fixed to the socket connected light bulb in a reflector known, two elastic components, e.g. Wire springs, which are rotatably mounted in tabs that are firmly connected to the reflector neck, can take two positions, the opening in a so-called opening position of the reflector so that the light bulb can be inserted or replaced can and in a so-called holding position, in which the springs resiliently on the version of the press the bulb inserted, lock the bulb.
two elastic components e.g. Wire springs, which are rotatably mounted in tabs that are firmly connected to the reflector neck, can take two positions, the opening in a so-called opening position of the reflector so that the light bulb can be inserted or replaced can and in a so-called holding position, in which the springs resiliently on the version of the press the bulb inserted, lock the bulb.
Such a lamp is also less suitable as a medical lamp, since it has no reserve lighting function in the event of failure of their single light bulb.
US-A 46 46 205 is a medical examination lamp with a parabolic Known reflector, which has a lamp holder for receiving an incandescent lamp. Also here only a single light bulb is provided for operating the medical lamp.
a cold light mirror lamp is known from DE-GM 89 12 262, the reflector has an opening for a lamp insert which, for reasons of exact adjustment, has a lamp firmly anchored to the insert with respect to the reflector.
the reflector Insert detachably connected to a socket arranged outside the reflector, wherein a precise connection between insert, reflector and socket Positioning of the light bulb is reached.
the object of the invention is to minimize storage costs to create a few components built medical lamp, on the one hand exact adjustment of the helix position within the reflector guaranteed, on the other hand allows the lamp to be changed without special technical knowledge; doing so Always an exact adjustment of the helix in the radial and axial direction of the reflector axis be achieved.
the flange essentially one has an oval or elliptical cross-section, the enlarged area at least a bushing for the electrical supply line and at least one pressing surface for Has support of a spring clip under pressure.
the simple and robust construction proves to be particularly advantageous, whereby the special Design of the lamp due to an undesirable contact with the bulb surface of the lamp base that can be used as a handle part can be avoided. As beneficial it proves that the lamp is prevented from rotating about its longitudinal axis.
the base has a cylindrical area to which the expanded area connects in the form of a plate flange.
the reflector is made of aluminum, the good ones Deformation properties in the production of the blank, and the ease of coating of the reflective surface prove to be advantageous.
As more heat-resistant and electrical Insulating material of the lamp base is preferably ceramic.
the flange is at least partially as a hollow cylinder educated.
the flange it is also possible for the flange to be essentially polygonal trained cross-section.
the cross section of the lateral surface is of the lamp base adapted to the cross section of the flange.
An additional lamp is advantageously used, the base of which is joined together the base of the first lamp forms a closed cross-sectional area, the outer contour of which is adapted to the inner contour of the flange.
the reflector 1 consists approximately of an ellipsoid of revolution, in the Focus area, which is shown schematically as zone 3 along the reflector axis 4 is the filament 5 of the lamp 6;
the reflective surface 2 has one Variety of groove-shaped flutes, or facets 8, as already in similar Form is known from the aforementioned US Patent 3,511,983; due to the facets 8 results a largely shadow-free and uniform illumination of the irradiated surgical field, or lighting field, since each facet covers almost the entire surgical or illuminating field.
the lamp lamp 6 or 6 'consisting of lamp bulb 7 and base 9 as to be replaced Lamp is along axis 4 in a circular opening 11 with a circumferential Inserted flange, the cylindrical part 10 of the base adjoining the piston 7 9 the lamp used against displacement in the radial direction and based on the additionally shown lamp 6 'recognizable plate flange 12 against axial displacement and Secures tilting.
the lamp 6 ′ is passed along the reflector axis 4 Opening 11 of the reflector inserted so that the cylindrical part 10 of the lamp from which the Opening 11 surrounding ring flange 13 against radial displacement and that on the outer edge of the ring flange 13 overlying plate flange 12 the lamp against axial displacement and tilting, an additional pressing element in the form of a bracket 14 is provided, which engages in a groove 17 on the back of the plate flange 12; by bracing by means of the pressure bracket to be attached to the outer flange 15 of the reflector 14 plate flange 12 is pressed against the ring flange 13, so that the lamp 6 is in an adjusted position.
a lamp 6 in the reflector 1 fails, the lamp 6 is moved along the reflector axis 4 pulled out of the reflector opening 11 in the rearward direction of the reflector and along a proper lamp as shown by lamp 6 ' the axis 4 replaced in opening 11 of the reflector; the cylindrical part 10 of the base 9 of the lamp 6 'in the opening 11 surrounded by a ring flange 13 along the axis 4 pushed in until plate flange 12 of lamp 6 on the outer edge of the ring flange comes to rest and the lamp by means of the cylindrical part 10 in a radial Direction and is locked in the axial direction by means of the plate flange 12; with the lock the helix position inside the reflector is also properly adjusted, since the Production of the lamp 6 of the bulb 7 with the filament 5 positioned relative to the base 9 that the later exact adjustment by simple exchange with subsequent locking the lamp 6 is guaranteed.
the lamp is used provided opening 11 carried out in an oval shape, wherein the surrounding the opening 11 Flange 13 also has an oval cross section; in this opening 11 are two, with their Lamps 6 ", 6" 'aligned parallel to one another in longitudinal axes can be used, whose bases 9 ", 9"' each form a half oval in cross-section, with both bases being in the inserted state add to an oval, the outer contour of the inner surface of the flange 13 without play is adapted; the oval is also shown schematically in FIG. 3b oval opening 11 within the reflector 1 provided with a plurality of facets 8 recognizable. A correspondingly adapted cross-sectional area is shown in FIGS.
