Infrarotfreies und ultraviolettfreies, weißes Licht diffus abstrahlendeInfrared-free and ultraviolet-free, white light diffusely emitting
ArbeitsleuchteWork light
Die Neuerung betrifft eine infrarotfreies und ultraviolettfreies, weißes Licht diffus abstrahlende Arbeitsleuchte mit mindestens zwanzig in einer Ebene angebrachten, lichtemittierenden Dioden.The innovation concerns an infrared-free and ultraviolet-free work lamp that diffusely emits white light with at least twenty light-emitting diodes arranged in one plane.
Aus der deutschen Auslegeschrift Nr. 2.227.322 ist ein Vergußmaterial, nämlich eine lichtdurchlässige Kunststoffmasse mit eingebettetem Glaspulver bekannt, von welchem das von einer Galliumarsenid-phosphid-Leuchtdiode emittierte Licht besonders breit gestreut und gleichmäßig verteilt wird, damit es sehr gut aus einem großen Blickwinkel erkannnt werden kann.From the German publication no. 2.227.322, a casting material is known, namely a translucent plastic mass with embedded glass powder from which the light emitted by a gallium arsenide phosphide light-emitting diode is scattered particularly widely and distributed evenly so that it can be recognized very well from a large viewing angle.
In der deutschen Offenlegungsschrift Nr. 19.542.416 sind Aordnungen von Leuchtdioden zum Erzeugen von Farbpixeln bekannt, die aus großer Entfernung beispielsweise über ein Baseball feld hinweg betrachtet werden. Um bei dieser Anwendung eine ausreichend hohe Intensität zu erreichen, ist eine große Anzahl von gebündelten Leuchtdioden in einer Röhre oder Hülse gruppiert,die auf einer Platine befestigt sind, auf deren Rückseite die Treiberelektronik vorgesehen ist. Gegebenenfalls werden vier rote, sieben grüne und neun blaue Dioden in einer einzigen Röhre zusammen gruppiert. Durch Auswahl der roten, grünen und blauen Anteile mit Hilfe individueller Adressiermittel können einzelne Farben wunschgemäß erzeugt werden. Wie ferner erwähnt ist, erzeugt eine streuende, beispielsweise sandgestrahlte Oberfläche eine wesentlich höhere Lichtintensität als ein normaler Leuchtdiodenmodul.In German Offenlegungsschrift No. 19,542,416, arrangements of light-emitting diodes are known for generating color pixels that are viewed from a great distance, for example across a baseball field. In order to achieve a sufficiently high intensity in this application, a large number of bundled light-emitting diodes are grouped in a tube or sleeve, which are attached to a circuit board, on the back of which the driver electronics are provided. If necessary, four red, seven green and nine blue diodes are grouped together in a single tube. By selecting the red, green and blue components with the aid of individual addressing means, individual colors can be generated as desired. As also mentioned, a scattering surface, for example a sandblasted surface, generates a significantly higher light intensity than a normal light-emitting diode module.
Bei den zuvor erläuterten, bekannten Anordnungen ist das von einem Diffusor abgestrahlte Licht unmittelbar zur Wahrnehmung durch das menschliche Auge bestimmt, das von sich aus sehr flexibel auch an geringe Lichtstärken wie die des Mondes von weniger als 1 Lux anzupassen in der Lage ist.In the known arrangements explained above, the light emitted by a diffuser is intended for immediate perception by the human eye, which is in itself very flexible in its ability to adapt to low light intensities such as the moon's light intensity of less than 1 lux.
In dem 'Lehrbuch der Experimentalphysik1 von Bergmann-Schaefer, Band III, 7. Auflage (1978), Seite 633, wird angegeben, daß eine Beleuchtungsstärke von 500 Lux zu normalen Arbeiten angemessen erscheint.In the 'Textbook of Experimental Physics 1' by Bergmann-Schaefer, Volume III, 7th edition (1978), page 633, it is stated that an illuminance of 500 lux seems appropriate for normal work.
Der Neuerung liegt die Aufgabe zugrunde, eine infrarotfreies und ultraviolettfreies, weißes Licht in einer Hauptrichtung diffus abstrahlende Arbeitsleuchte zum Beleuchten einer Arbeitsfläche mit mindestens 500 Lux anzugeben.The innovation is based on the task of specifying an infrared-free and ultraviolet-free work lamp that emits white light diffusely in one main direction to illuminate a work surface with at least 500 lux.
Diese Aufgabe wird gemäß der Neuerung dadurch gelöst, daß mindestens zwanzig in einer Ebene angebrachte, lichtemittierende Dioden eng benachbart im Innenraum eines Gehäuses mit Abstand von einer den Innenraum abschließenden, das Licht diffus durchlassenden Prägescheibe angeordnet sind.According to the innovation, this task is solved by arranging at least twenty light-emitting diodes mounted in one plane closely adjacent to one another in the interior of a housing at a distance from an embossed disk that closes off the interior and diffuses the light.
Eine Ausführungsform einer Arbeitsleuchte gemäß der Neuerung ist in der Zeichnung dargestellt und wird im folgenden ausführlich erläutert.An embodiment of a work lamp according to the innovation is shown in the drawing and is explained in detail below.
Die einzige Figur zeigt eine Arbeitsleuchte, die nur weißes oder farbiges, jedoch von infraroter und ultravioletter Strahlung freies Licht aussendet. Wegen der ausbleibenden Wärmestrahlung und Wärmeentwicklung wird sie zur Beleuchtung gewisser Arbeitsbereiche an Näh- oder Schuhmaschinen eingesetzt, insbesondere wenn vom Bedienungspersonal über längere Zeit hinweg bei guter Beleuchtung irgendwelche Handarbeiten an Textil bahnen ausgeführt werden müssen. Kurz gesagt, werden die Bedienenden hierbei vor störender Wärme- und ultravioletter Strahlung geschützt.The only figure shows a work lamp that only emits white or colored light, but is free of infrared and ultraviolet radiation. Because it does not emit heat or generate heat, it is used to light certain work areas on sewing or shoe machines, especially when the operating personnel have to carry out manual work on textile strips for a long time in good lighting. In short, the operators are protected from disturbing heat and ultraviolet radiation.
Die gezeigte Arbeitsleuchte wird aus dem üblichen Netz mit einer Wechselspannung von etwa 220 Volt über einen Transformator (nicht gezeigt) gespeist. Von der Sekundärwicklung des Transformators wird eine Spannung von 24 Volt über ineinem Haltegestänge 4 verlegte Drähte zu einem von Hand betätigbaren Schalter 1 und einem Modul 6 herangeführt, der mit mindestens 20 lichtemittierenden Dioden bestückt ist. In Abhängigkeit von der erwüschten spektralen Zusammensetzung des Lichtes, beispielsweise bläulich-weiß, rötlich-weiß oder gelblich-weiß, wird die nötige Art und Zahl der lichtemittierenden Dioden ausgewählt.The work light shown is powered from the usual mains with an alternating voltage of around 220 volts via a transformer (not shown). A voltage of 24 volts is supplied from the secondary winding of the transformer via wires laid in a support rod 4 to a manually operated switch 1 and a module 6, which is equipped with at least 20 light-emitting diodes. The required type and number of light-emitting diodes are selected depending on the desired spectral composition of the light, for example bluish-white, reddish-white or yellowish-white.
Ohne das Haltegestänge 4 betragen die Abmessungen der zylindrischen Arbeitsleuchte 75 &khgr; 70 mm und sind vornehmlich durch ein rohrförmiges Gehäuse 5 gegeben, dessen Innenraum an der einen Seite von einem den Schalter 1 tragenden Deckel 2 und an der anderen Seite von einer lichtdurchlässigen Scheibe 8 aus Glas oder einem glasartigen Kunststoff abgeschlossen ist, der teilweise ultraviolettes Licht absorbiert. Während die nach innen gekehrte Fläche der Scheibe 8 plan ist, ist ihre nach außen gewendete Fläche derart geprägt, als ob sie dicht von kaum wahrnehmbaren, linsenartigen Vorsprüngen (nicht gezeigt) bedeckt wäre. Die Scheibe 8 wird an ihrem kreisförmigen Rand im rohrförmigen Gehäuse 5 von einer ringförmigen Fassung 7 festgehalten, die zugleich die Austrittsöffnung für das von den lichtemittierenden Dioden erzeugte, infrarotfreie Licht bildet, das in erster Linie in RichtungWithout the support rod 4, the dimensions of the cylindrical work light are 75 x 70 mm and are primarily defined by a tubular housing 5, the interior of which is closed on one side by a cover 2 carrying the switch 1 and on the other side by a translucent disk 8 made of glass or a glass-like plastic that partially absorbs ultraviolet light. While the inward-facing surface of the disk 8 is flat, its outward-facing surface is shaped as if it were tightly covered by barely perceptible, lens-like projections (not shown). The disk 8 is held at its circular edge in the tubular housing 5 by an annular mount 7, which also forms the exit opening for the infrared-free light generated by the light-emitting diodes, which is primarily directed in the direction of

der optischen Achse von der Leuchte weg geworfen wird. Je nach der Zahl und Art (= Farbe) der eingesetzten Dioden liegt der Stromverbrauch der Arbeitsleuchte zwischen 1,5 und 2,6 Watt. In einem Abstand von 10 cm wurde eine Beleuchtungsstärke von ca. 1.000 Lux gemessen; bei einem Abstand von 1 m zwischen der Leuchte und einer Arbeitsfläche von 60 cm Durchmesser wird somit die für ormale Arbeiten nötige Beleuchtungsstärke von 500 Lux erreicht, wobei der Abstrahlwinkel 30° beträgt. Die beobachtete Lebensdauer dieser Arbeitsleuchte liegt bei 35.000 Stunden, was etwa vier Jahren entspricht. Im Hinblick hierauf erscheint in vielen Fällen die Anordnung des Schalters 1 innerhalb des Deckels 2 überflüssig, weil die Maschine und die angebrachte Arbeitsleuchte zugleich an- oder abgeschaltet werden können.the optical axis is thrown away from the lamp. Depending on the number and type (= color) of the diodes used, the power consumption of the work lamp is between 1.5 and 2.6 watts. At a distance of 10 cm, an illuminance of around 1,000 lux was measured; at a distance of 1 m between the lamp and a work surface with a diameter of 60 cm, the illuminance of 500 lux required for normal work is thus achieved, with the beam angle being 30°. The observed service life of this work lamp is 35,000 hours, which corresponds to around four years. In view of this, in many cases the arrangement of the switch 1 inside the cover 2 appears superfluous, because the machine and the attached work lamp can be switched on or off at the same time.
Nun sei auf weitere Anwendungsmöglichkeiten der Arbeitsleuchte gemäß der Neuerung bezuggenommen:Now let us look at further possible applications of the work light according to the innovation:
Aus der deutschen Patentschrift Nr. 3.613.610 ist ein Kühlregal bekannt, bei dem auf die mit Abstand übereinander angeordneten Regalböden die zu kühlenden Waren wie Lebensmittel und Getränke durch das Ladenpersonal von Hand gelegt und zu einem späteren Zeitpunkt durch die Kunden ausgewählt und von Hand entnommen werden. Diese Regal boden mit den aufzulegenden Waren stellen folglich gleichfalls Arbeitsflächen dar, die, wie bekannt, von Scheinwerfern beleuchtet werden. - Da jede Wärmezufuhr so auch durch infrarote Strahlung in das Kühlmöbel hinein einen Energieverlust mit sich bringt, können anstelle der Scheinwerfer die Arbeitsleuchten gemäß der Neuerung zur Handhabung der Waren an einem Kühlregal oder einem ähnlichen Kühlmöbel angebracht sein.A refrigerated display cabinet is known from German patent specification No. 3,613,610, in which the goods to be refrigerated, such as food and drinks, are placed by the store staff by hand on shelves arranged at a distance from one another, and are then selected and removed by the customer by hand at a later time. These shelves with the goods to be placed on them therefore also represent work surfaces, which, as is known, are illuminated by spotlights. - Since any heat supply, including infrared radiation, into the refrigerated cabinet results in an energy loss, the work lights for handling the goods can be attached to a refrigerated display cabinet or similar refrigerated cabinet instead of spotlights, according to the innovation.
In ähnlicher Weise soll jede Wärmezufuhr durch infrarote Strahlung zu wärmeempfindlichen Gegenständen, zu denen auch Lebewesen gezählt werden können, vermieden werden. Derartige Gegenstände sind häufig zwecks Schaustellung in geschlossenen Vitrinen untergebracht und werden von außen beleuchtet. Ähnliches gilt für Tiere und Pflanzen, die in Terrarien oder Aquarien leben und zur Sichtbarmachung von außen zu beleuchten sind.Similarly, any heat supply from infrared radiation to heat-sensitive objects, which can also include living creatures, should be avoided. Such objects are often housed in closed display cases for display purposes and are illuminated from the outside. The same applies to animals and plants that live in terrariums or aquariums and must be illuminated from the outside to make them visible.
In all diesen Fällen sind eine oder mehrere passend angebrachte Arbeitsleuchten gemäß der Neuerung verwendbar, um eine Erwärmung des eingeschlossenen gasförmigen oder flüssigen Mediums, meeistens Luft oder Wasser zu unterbinden. In all of these cases, one or more suitably installed work lights can be used according to the innovation to prevent heating of the enclosed gaseous or liquid medium, usually air or water.
