Description
Die Erfindung betrifft eine Lupe, mit den weiteren Merkmalen des Oberbegriffes des Anspruchs 1.The invention relates to a magnifying glass, with the further features of the preamble of claim 1.
Derartige Lupen weisen in der Regel eine topfartige Halterung auf, um das Lupenglas aufzunehmen. Außerdem ist es bereits bekannt, ein Beleuchtungselement vorzusehen, um eine Fläche, die durch die Lupe betrachtet werden soll, besser an- oder auszuleuchten.Such magnifying glasses usually have a pot-like holder to the Record magnifying glass. It is also known to be a Lighting element to provide an area viewed through a magnifying glass should be better illuminated or illuminated.
Als Stand der Technik (DE 196 53 234 A1) ist es bekannt, als Lichtquellen herkömmliche Glühlampen oder Halogenlampen vorzusehen. All diese Lichtquellen haben den Nachteil, daß sie zum einen relativ groß sind und relativ viel Wärme abstrahlen, zum anderen auch nur eine begrenzte Lebensdauer haben und deswegen von Zeit zu Zeit ausgetauscht werden müssen. Außerdem benötigen die eingesetzten Lichtquellen relativ viel Energie, was in nachteiliger Weise dazu führt, daß Batterien relativ oft ausgetauscht werden müssen.It is known as prior art (DE 196 53 234 A1) that conventional light bulbs are used as light sources or halogen lamps. All of these light sources have that Disadvantage that on the one hand they are relatively large and radiate a lot of heat, on the other hand, they only have a limited lifespan and therefore time need to be replaced at time. In addition, the used Light sources relatively much energy, which leads to the disadvantage that Batteries need to be replaced relatively often.
Der Erfindung liegt die Aufgabe zugrunde, eine Handlupe mit den Merkmalen des Oberbegriffes des Anspruches 1 derart auszubilden, daß ein Wechsel der Lichtquelle bei angenommener normaler Lebensdauer der Lupe entfallen kann und der Leistungsverbrauch erheblich reduziert wird.The invention is based, a hand magnifier with the features of the task The preamble of claim 1 form such that a change of Light source with assumed normal life of the magnifying glass can be omitted and the power consumption is significantly reduced.
Diese Aufgabe wird durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst. Vorteilhafte Weiterbildungen ergeben sich aus den Unteransprüchen 2-5.This object is achieved by the characterizing features of claim 1 solved. Advantageous further developments result from subclaims 2-5.
Durch die Verwendung von Hochleistungs-LEDs, insbesondere Hochleistungskeramik-LEDs in Verbindung mit einer Handlupe wird eine Mehrzahl von Vorteilen erreicht. Zunächst läßt die kleine Baugröße der Hochleistungs-LED, insbesondere Hochleistungskeramik-LED auch den Einbau in relativ filigrane Halterungen und Gehäuse zu. Die Gehäuse können schlanker und leichter gestaltet werden und sind deswegen auch über einen längeren Zeitraum mühelos in der Hand zu halten.Through the use of high power LEDs, in particular High-performance ceramic LEDs combined with a handheld magnifier become one Achieved a number of advantages. First, the small size of the High-performance LED, in particular high-performance ceramic LED also for installation in relatively filigree brackets and housings. The housings can be slimmer and be made lighter and are therefore also longer Effortlessly hold period in hand.
Bei geringem Gewicht haben die Hochleistungs-LEDs, insbesondere Hochleistungskeramik-LEDs außerdem eine hohe Lichtausbeute und eine annähernd unbegrenzte Lebensdauer von ca. 100.000 Stunden bei Dauerbetrieb, so daß sehbehinderten Menschen, die die Hauptnutzergruppe solcher vergrößernden Sehhilfen wie Handluken darstellen, ein relativ schwieriger Lampenwechsel erspart bleibt.At low weight, the high-performance LEDs, in particular High-performance ceramic LEDs also have a high luminous efficiency and a almost unlimited lifespan of approx. 100,000 hours in continuous operation, so that visually impaired people who are the main user group of such magnifying visual aids such as hatches represent a relatively difficult one Lamp replacement is spared.
Durch die geringe Stromaufnahme sind auch Batteriewechsel nur selten erforderlich. Auch mit Wechsel von Batterien haben ältere sehbehinderte Menschen große Probleme, die dann entfallen.Due to the low power consumption, battery changes are also rare required. Even with changing batteries, older visually impaired Big problems for people, which then disappear.
Seltener Batteriewechsel führt auch zu einer geringeren Umweltbelastung und einer erheblichen Kostenersparnis für den Nutzer.Rarely changing the battery also leads to a lower environmental impact and considerable cost savings for the user.
Aufgrund der kompakten Bauweise der Hochleistungs-LEDs, insbesondere Hochleistungskeramik-LEDs ist es außerdem erfindungsgemäß möglich, eine Mehrzahl von Hochleistungs-LEDs, insbesondere Hochleistungskeramik-LEDs kreisförmig verteilt auf einen Beleuchtungsträger anzuordnen, so daß die Probleme einer punktförmigen Lichtquelle entfallen, insbesondere ein Blend- oder Glanzeffekt auf glattem Papier.Due to the compact design of the high performance LEDs, in particular High-performance ceramic LEDs, it is also possible according to the invention, a Plurality of high-performance LEDs, especially high-performance ceramic LEDs to be arranged in a circle on a lighting support so that the Problems of a point light source are eliminated, in particular a glare or Gloss effect on smooth paper.
Ferner ist es möglich, die Mehrzahl von Hochleistungs-LEDs, insbesondere Hochleistungskeramik-LEDs mit unterschiedlichen Abstrahlwinkeln anzuordnen, wodurch eine noch bessere "breitbandige" Beleuchtung einer Fläche möglich wird.It is also possible to use the plurality of high-power LEDs, in particular Arrange high-performance ceramic LEDs with different beam angles, which enables an even better "broadband" illumination of an area becomes.
Die Erfindung ist anhand von Ausführungsbeispielen in den Zeichnungsfiguren näher erläutert. Diese zeigen:The invention is based on exemplary embodiments in the drawing figures explained in more detail. These show:
Fig. 1 eine Hochleistungs-LED, insbesondere Hochleistungskeramik- LED-Anordnung in einem geschlossenen Lupentopf; Fig. 1 is a high-power LED, in particular Hochleistungskeramik- LED array in a closed pot magnifier;
Fig. 2 eine Draufsicht auf die Hochleistungs-LED, insbesondere Hochleistungskeramik-LED-Anordnung im Lupentopf; Figure 2 is a plan view of the high power LED, in particular high-performance ceramic LED array in the magnifying glass pot.
Die vergrößernde optische Sehhilfe 1 weist eine Halterung 2 auf, die das vergrößernde optische Element 3 trägt. Außerdem ist ein Beleuchtungsele ment 4 vorgesehen, das mit einer Energiequelle 5 verbunden und an der Halterung 2 befestigt ist. Das Beleuchtungselement 4 ist eine Hochleistungs-LED, insbesondere Hochleistungskeramik-LED 6. Die Verbindung zur Halterung 2 erfolgt über einen Beleuchtungsträger 7, der bei dem in Fig. 1 dargestellten Ausführungsbeispiel an der Frontseite 8 der Griffhülse 9 eines Leseglases befestigt ist.The magnifying optical visual aid 1 has a holder 2 which carries the magnifying optical element 3 . In addition, a lighting element 4 is provided, which is connected to an energy source 5 and fastened to the holder 2 . The lighting element 4 is a high-performance LED, in particular high-performance ceramic LED 6 . The connection to the holder 2 is made via a lighting bracket 7 , which in the embodiment shown in FIG. 1 is attached to the front 8 of the grip sleeve 9 of a reading glass.
Bei dem in Fig. 1 und 2 dargestellten Ausführungsbeispielen ist die Mehrzahl von Hochleistungs-LEDs, insbesondere Hochleistungskeramik-LEDs 6 unter dem Rahmen 10 eines Lupentopfes 11 einer Handlupe angeordnet, und zwar in einer kreisförmigen Anordnung, die in Fig. 4 ersichtlich ist. Der Beleuchtungsträger 7 dient bei dem in Fig. 4 dargestellten Ausführungsbeispiel gleichzeitig als Halter für das Lupenglas.In the exemplary embodiments shown in FIGS . 1 and 2, the plurality of high-power LEDs, in particular high-performance ceramic LEDs 6, are arranged under the frame 10 of a magnifying glass 11 of a hand-held magnifier, in a circular arrangement which can be seen in FIG. 4. In the exemplary embodiment shown in FIG. 4, the lighting support 7 also serves as a holder for the magnifying glass.
