Unterwasser HandlampeUnderwater flashlight
Stand der TechnikState of the art
Unterwasser-Handlampen zum Tauchen sind bekannt und in manigfachen Ausführungen handelsüblich.Underwater hand lamps for diving are well known and are commercially available in many different designs.
An solche, beispielsweise zum Tauchen mitgeführten Unteru/asser-Handlampen werden entsprechend Ihrem Verwendungszweck unterschiedliche und zum Teil einander widersprechende Forderungen gestellt. Die Lampe soll eine hohe Lichtintensität ausstrahlen bei möglichst geringer Strohmaufnähme. Dabei sind Tag- und Nachtbenutzung der Lampe zu unterscheiden, wobei zum Einen ein Spot mit hoher Lichtintensität und zum Anderen ein breiter Strahl mit geringer Leistung benötigt wird. Ebenso soll sie eine einfache Handhabung sowie eine übersichtliche Kontrolle über den Ladezustand aufweisen .Such underwater hand lamps, for example those used for diving, have different and sometimes contradictory requirements depending on their intended use. The lamp should emit a high light intensity while using as little power as possible. A distinction must be made between day and night use of the lamp, with a spot with high light intensity and a wide beam with low power being required. It should also be easy to use and provide clear control of the charge level.
Auf dem Markt gibt es beispielsweise Lampen, bei denen die Strohmauf nähme gedrosselt u/erden kann; nimmt man aber die Spannung z.B. bei einem 50 Watt Strahler von 50 Watt auf 20 Watt zurück, so läßt die Lichtintensität sehr zu wünschen übrig, da sich dadurch in erster Linie die Farbtemperatur nach unten verschiebt, «/as den Wirkungsgrad stark vermindert.For example, there are lamps on the market where the power consumption can be throttled; however, if you reduce the voltage from 50 watts to 20 watts in a 50 watt spotlight, for example, the light intensity leaves a lot to be desired, as this primarily shifts the color temperature downwards, which greatly reduces the efficiency.
Vorteile der Erfindung Advantages of the invention
Der Erfindung liegt die Aufgabe zugrunde, eine Unterwasser—Handlampe ohne die oben genannten Nachteile zu entwickeln. Diese Aufgabe wird dadurch gelöst, daß mehrere, vorzugsweise drei, Strahler vorgesehen werden, die den unterschiedlichen Ansprüchen an Licht in verschiedenen Situationen gerecht werden, und außerdem ein hohes Maß an Sicherheit gegen Ausfall bieten. Die Lampe ist mit nur einer Hand bedien- und überwachbar , damit die Bewegunsfreiheit beim Tauchen nicht eingeschränk wird.The invention is based on the task of developing an underwater hand lamp without the disadvantages mentioned above. This task is solved by providing several, preferably three, spotlights that meet the different requirements for light in different situations and also offer a high degree of safety against failure. The lamp can be operated and monitored with just one hand so that freedom of movement is not restricted when diving.
Die Erfindung betrifft eine Unterwasser-Handlampe mit aufladbaren NC-Accus, mit einem im wesentlichen zylinderförmigen wasser- und druckdichten Aluminiumguß-Gehäuse, dessen Vorderfront nur drei Strahler und dessen Rückseite eine Öffnung für einen Ladestecker aufweist, sowie mit einem seitlich am Gehäuse angebrachten Handgriff aus GFK mit integriertem Schalter und Ladeanzeige der Akkus.The invention relates to an underwater hand lamp with rechargeable NC batteries, with an essentially cylindrical water- and pressure-tight cast aluminum housing, the front of which has only three spotlights and the back of which has an opening for a charging plug, as well as with a handle made of GRP attached to the side of the housing with an integrated switch and charging indicator for the batteries.
Nach einer vorteilhaften Ausgestaltung der Erfindung ist in einem Gehäuse anstatt eines einzigen Reflektors eine Frontplatte mit der Möglichkeit zur Anbringung von mehreren Reflektoren, vorzugsweise drei, eingesetzt.According to an advantageous embodiment of the invention, instead of a single reflector, a front plate with the possibility of attaching several reflectors, preferably three, is used in a housing.
Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung sind drei Halogenstrahler mit unterschiedlicher Leistung und Abstrahlcharakteristik vorhanden, die jeweils einzeln zu schalten und miteinander kombinierbar sind.According to a further advantageous embodiment of the invention, there are three halogen spotlights with different power and radiation characteristics, which can each be switched individually and combined with one another.
Nach einer weiteren vorteilhaften Ausgestaltung der
Erfindung ist die Leuchtbandanzeige am Griff radial nach außen angeordnet. Der anatomisch geformte Handgriff
mit integrierter Elektronik bietet vorteilhafterweise
die Möglichkeit, den Ladezustand der Akkus im Betrieb jederzeit zu überwachen. Da die mehrfarbige
Leuchtbandanzeige im Blickfeld des Benutzers angebracht
ist wird dieser sofort auf die Änderung des Ladezustandes aufmerksam gemacht und dadurch vor überraschendem
Absinken der Akkuspannung gewarnt.
Die Strahler werden über Reed—Kontakte geschaltet, die ebenfalls im Griff angeornet sind. Somit kann die Lampe
mit einer Hand bedient werden , was die Bewegungsfreiheit des Benutzers wesentlich erleichtert.According to a further advantageous embodiment of the invention, the light strip display is arranged radially outwards on the handle. The anatomically shaped handle with integrated electronics advantageously offers the possibility of monitoring the charge level of the batteries at any time during operation. Since the multi-colored light strip display is located in the user's field of vision, the user is immediately alerted to the change in the charge level and is thus warned of a sudden drop in the battery voltage.
The spotlights are switched via reed contacts, which are also located in the handle. This means that the lamp can be operated with one hand, which significantly facilitates the user's freedom of movement.
Weitere Vorteile und vorteilhafte Ausgestaltungen der Erfindung sind der nachfolgenden Beschreibung, der Zeichnung und den Ansprüchen entnehmbar.Further advantages and advantageous embodiments of the invention can be found in the following description, the drawings and the claims.
