Abstract

The invention relates to a lamp device which is worn on or directly in front of the forehead, respectively, or above or beside the eyes, respectively, and which ensures that the wearer's freedom of movement is neither restricted nor hindered by cables or other connections. The present invention is special in that several non-thermal, light-emitting elements are provided for the generation of light and that the individual light-emitting elements emit the light in a defined direction of radiation and are located in such a way that the light which is generated is directional. The light-emitting elements are located in such a way that each of them forms a particular angle with the visual axis of the wearer so that all light sources have a common intersection point just at the wearer's monitoring or working distance, respectively. Moreover, all individual light-emitting elements have the same distance to that intersection point. Furthermore, the vertical position of the area of illumination may be varied in front of the wearer's face.

Gegenstand der Erfindung ist eine Leuchte, die auf bzw. unmittelbar vor der Stirn bzw. oberhalb oder neben den Augen getragen wird, und durch die der Verwender der Leuchte weder durch Kabel oder sonstige Verbindungen in seiner Bewegungsfreiheit eingeschränkt oder behindert wird. Eine solche Leuchte ist z.B. für medizinische Anwendungen, zur Ausleuchtung des Behandlungsgebietes während der Diagnose oder Behandlung gedacht. Jedoch ist diese Leuchte auch für nicht-medizinsche Anwendungen, bei denen eine ähnliche Beleuchtungsproblematik vorliegt, ebenfalls einsetzbar.The invention relates to a lamp which is worn on or immediately in front of the forehead or above or next to the eyes, and by which the user of the lamp is neither restricted nor hindered in his freedom of movement by cables or other connections. Such a lamp is e.g. for medical applications, to illuminate the treatment area during diagnosis or treatment. However, this lamp can also be used for non-medical applications in which there is a similar lighting problem.
Kopfgetragene Leuchten und Beleuchtungsvorrichtungen wurden insbesondere für den medizinischen Bereich in unterschiedlichen Ausführungen konzipiert. Dabei wird das Licht entweder a) direkt vor oder auf dem Kopf des Verwenders erzeugt, oder b) in einer externen Lichtquelle erzeugt und über Lichtleiter aus Glas, Kunststoff oder Flüssigkeit an die Stirnseite des Verwenders geleitet. Im Falle b) wird die Bewegungsfreiheit des Verwenders durch das Lichtleitkabel mehr oder weniger behindert bzw. eingeschränkt, und das Gewicht des Lichtleiters erzeugt eine unangenehme Zugspannung, die zu Muskelverspannung im Nacken, zu Kopfschmerzen oder anderen vorzeitigen Ermüdungserscheinungen führt. Im Falle a) sind zwar auch kabellose Energiequellen im Einsatz, die unbehinderte Kopfbewegungen des Verwenders der Leuchte zulassen, doch sind die verwendeten Lichtquellen thermischer Natur, was zur Folge hat, daß vor oder oberhalb der Stirn des Verwenders erhebliche Wärme entsteht. Weiters erfolgt der Lichterzeugungsprozeß mit geringem Wirkungsgrad, so daß die übücherweise verwendeten Akkupakete oder Batterien relativ schwer sind, was wiederum zu den oben erwähnten Ermüdungserscheinungen führt. Hinzu kommt, daß das Licht der thermischen Lichtquellen erst mittels geeigneter Optiken gebündelt werden muß, was zu relativ hohem Gewicht und unhandlichen Abmessungen dieser Kopfleuchten führt.Head-mounted lights and lighting devices were designed in different versions, especially for the medical field. The light is either a) generated directly in front of or on the head of the user, or b) generated in an external light source and directed to the end of the user via light guides made of glass, plastic or liquid. In case b) the freedom of movement of the user is more or less hindered or restricted by the light guide cable, and the weight of the light guide creates an uncomfortable tension that leads to muscle tension in the neck, to headaches or other premature signs of fatigue. In case a) there are also wireless energy sources in use which allow the head of the user of the lamp to move freely, but the light sources used are thermal in nature, with the result that considerable heat is generated in front of or above the forehead of the user. Furthermore, the light generation process is carried out with low efficiency, so that the accumulator packs or batteries used conventionally are relatively heavy, which in turn leads to the fatigue phenomena mentioned above.

Figur 7: Zeigt eine weitere bevorzugte Ausführungsform, bei der die hchtemittierenden Elemente (1) an einem eigenen Koptträger abgebracht sind. Die hchtemittierenden Elemente (1) sind an einem Halteteil (2) montiert, der an einer Stütze (9) so befestigt ist, daß sich das Beleuchtungsfeld in vertikaler Richtung verschieben und so den Beobachtungserfordernissen des Verwenders anpassen läßt. Der Kopfhalter besteht aus einem verstellbaren Kopfband (11), das durch zwei zusätzliche Bänder (ein längslaufendes (12) und ein querlaufendes (13)) gegen Herabrutschen gesichert wird. Diese beiden Zusatzbänder sind ebenfalls in ihrer Länge verstellbar und zwar in deren Kreuzungspunkt (14). Im Stirnbereich ist eine Stütze (9) fix mit dem Kopfband (11) verbunden, an dessen beiden Armen der Halteteil (2) drehbar befestigt ist. Im Bereich des Hinterkopfes ist die Stromversorgung (4) untergebracht, die entweder in Form von Batterien oder wiederaufladbaren Akkus bestehen kann. Die Anbringung genau gegenüber dem stirnseitigen Schwenkteil ermöglicht einen zumindest teilweisen Gewichtsausgleich und damit eine Verringerung der Muskelspannung im Nacken des Trägers der Beleuchtungsvorrichtung. Die Strorrizuführung von der Stromversorgung (4) zu den hchtemittierenden Elementen erfolgt über eine zweipolige Leitung (6), die von den Batterien entlang dem Kopfband über den rechten Arm der Stütze bis zu einem Schalter (5) geführt wird. Dieser Schalter (5) ist rechts oben im Halteteil (2) untergebracht, so daß er mühelos mit der rechten Hand betätigt werden kann, während die Beleuchtungsvorrichtung auf dem Kopf getragen wird.FIG. 7: shows a further preferred embodiment, in which the high-emission elements (1) are removed on a separate head carrier. The light-emitting elements (1) are mounted on a holding part (2) which is fastened to a support (9) in such a way that the illumination field can be moved in the vertical direction and can thus be adapted to the user's observation requirements. The head holder consists of an adjustable head band (11), which is secured against slipping by two additional bands (one longitudinal (12) and one transverse (13)). The length of these two additional bands can also be adjusted, namely at their crossing point (14). In the forehead area, a support (9) is fixedly connected to the headband (11), on the two arms of which the holding part (2) is rotatably fastened. In the area of the back of the head is the power supply (4), which can either be in the form of batteries or rechargeable batteries. The attachment exactly opposite the front swivel part enables at least partial weight compensation and thus a reduction in the muscle tension in the neck of the wearer of the lighting device. The power supply from the power supply (4) to the high-emission elements is via a two-pole line (6), which is led from the batteries along the headband over the right arm of the support to a switch (5). This switch (5) is housed in the upper right part of the holding part (2), so that it can be easily operated with the right hand while the lighting device is worn on the head.
Mit der erfindungsgemäßen Anordnung der Hchtemittierenden Elemente (1) ist gewährleistet, daß das mit hoher Effizienz nic t- ermisch erzeugte Licht optimal für die Beleuchtung des Beobachtungs- bzw. Arbeitsgebietes genutzt wird. Dies führt dazu, daß einerseits das Gewicht der beschriebenen Kopfleuchte minimal gehalten werden kann, da die für die Energieversorgung notwendigen Energiequellen bzw. Energiespeicher sehr klein dimensioniert werden können, andererseits die störende Wärmeerzeugung vor bzw. am Kopf des Verwenders auf ein Minimum reduziert ist. Damit ist ein optimaler Tragekomfort für den Verwender gegeben. Die Verwendung mehrerer hchtemittierenden Elemente (1) gewährleistet darüber hinaus, daß Werkzeuge oder Instrumente, die während des Arbeitens mit der beschriebenen Kopfleuchte im Bereich des Beobachtungsieides verwendet werden, das Beleuchtungshcht nur teilweise abschatten können und somit jederzeit eine ausreichende Beleuchtung gegeben ist. With the arrangement according to the invention of the light-emitting elements (1) it is ensured that the light which is not nicely generated with high efficiency is optimal for the Illumination of the observation or work area is used. This means that, on the one hand, the weight of the head lamp described can be kept to a minimum, since the energy sources or energy stores required for energy supply can be dimensioned very small, and on the other hand, the annoying heat generation in front of or on the head of the user is reduced to a minimum. This ensures optimal comfort for the user. The use of several light-emitting elements (1) also ensures that tools or instruments that are used while working with the headlamp described in the area of the oath of observation can only partially shade the illuminating light and thus provide adequate lighting at all times.
