Beleuchtete Tastatur für einen ComputerIlluminated keyboard for a computer BeschreibungDescription

Die Erfindung betrifft eine beleuchtete Tastatur für einen Computer.The invention relates to an illuminated keyboard for a computer.

Eine beleuchtete Tastatur für einen Computer ist aus der DE 94 04 797.9 Ul bekannt. Dabei wird ein Computer mit einer Leuchte ausgestattet, die sich oberhalb der Tastatur, aber unterhalb des Monitors befindet und zu diesem abgeschirmt ist, um Lichtspiegelungen zu vermeiden. Eine derartige Beleuchtung ist für tragbare Computer (Laptop, Notebook, ...) unbrauchbar, da sich bei diesen zwischen der Tastatur und dem Bildschirm keine Beleuchtung mit Abschirmung einfügen laßt.An illuminated keyboard for a computer is known from DE 94 04 797.9 Ul. A computer is equipped with a light that is located above the keyboard, but below the monitor and is shielded from it in order to avoid light reflections. Such lighting is unusable for portable computers (laptops, notebooks, etc.) because it is not possible to insert a shielded lighting between the keyboard and the screen.

Der Erfindung liegt daher die Aufgabe zugrunde, eine beleuchtete Tastatur verfügbar zu machen, die sich in einen tragbaren Computer integrieren läßt.The invention is therefore based on the object of making available an illuminated keyboard that can be integrated into a portable computer.

Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß mindestens eine Lichtquelle unterhalb der Tastenoberflächen angeordnet ist und daß die Tastenflächen und die ihnen zugeordneten Zeichen eine derart unterschiedliche Lichtemission aufweisen, daß die Zeichen deutlich erkennbar sind.The object is achieved according to the invention in that at least one light source is arranged below the key surfaces and that the key surfaces and the characters assigned to them have such a different light emission that the characters are clearly recognizable.

Durch die Erfindung wird es möglich, mit einem tragbaren Computer auch im Dunklen zu arbeiten, ohne daß eine externe Lichtquelle zur Verfugung stehen muß. Dies eröffnet völlig neue Möglichkeiten, beispielsweise auf Reisen, wenn eine externe Beleuchtung entweder nicht zur Verfügung steht oder wenn Mitreisende nicht gestört werden sollen. Mit dem Computer läßt sich so auch in Nachtzügen oder als Beifahrer im PKW arbeiten. Auch der Einsatz für Berufsgruppen, die nachts im Freien arbeiten müssen, wie Bundeswehr, Polizei, Bundesgrenzschutz usw., ist möglich. Selbstverständlich wird ein Computer mit den vorgeschlagenen beleuchteten Tasten auch von anderen Benutzern angenommen, die Lichteinflüsse vermeiden wollen, um kreativ schaffen zu können, oder sich dafür begeistern, ohne Licht im Internet zu „surfen".The invention makes it possible to work with a portable computer in the dark without having to have an external light source available. This opens up completely new possibilities, for example when traveling, when external lighting is either not available or when you don't want to disturb your fellow travelers. The computer can also be used on night trains or as a passenger in a car. It can also be used by professional groups who have to work outdoors at night, such as the German army, police, federal border guard, etc. Of course, a computer with the suggested illuminated keys will also be accepted by other users who want to avoid the effects of light in order to be able to create creatively, or who are enthusiastic about "surfing" the Internet without light.

Ein weiterer Vorteil der erfindungsgemäßen Lösung besteht darin, daß die Beleuchtung immer, wenn der Computer benutzt werden soll, zur Verfugung steht. Es ist auch keine separate Energiequelle erforderlich, da die erfmdungsgemäße Beleuchtung nur das beleuchtet, was erforderlich ist, daher mit der Energie sparsam umgeht und durch den Akku des Computers betrieben werden kann. Wegen der geringen Beleuchtungsstärke wird auch keine Abschirmung benötigt.A further advantage of the solution according to the invention is that the lighting is always available when the computer is to be used. No separate energy source is required either, since the lighting according to the invention only illuminates what is required, therefore uses energy economically and can be operated by the computer's battery. Due to the low lighting intensity, no shielding is required either.

Die Lichtquelle kann aus einer lumineszierenden Substanz wie bei einem Leuchtzifferblatt bestehen oder als elektrische Lichtquelle ausgebildet sein, die vom Akku des Computers gespeist wird. Es ist möglich, daß nur die Zeichen oder nur die Tastenflächen leuchten, die die Zeichen umgeben. Am besten erkennbar sind jedoch stark leuchtende Zeichen auf schwach leuchtenden Tastenflächen, was durch Zeichen mit starker Lichtemission auf Tastenflächen mit schwacher Lichtemission erreicht wird,
15The light source can consist of a luminescent substance, such as a luminescent dial, or it can be an electrical light source powered by the computer's battery. It is possible that only the characters or only the key areas surrounding the characters light up. However, the best way to see them is to have highly luminous characters on weakly luminous key areas, which is achieved by placing characters with strong light emission on key areas with weak light emission.

Eine vorteilhafte Ausführungsform sieht vor, daß mindestens eine Lichtquelle zwischen den Tastenflächen und der Bodenplatte der Tastatur angeordnet ist und daß die Tastenflächen und die auf ihnen angeordneten Zeichen eine unterschiedliche Lichtdurchlässigkeit aufweisen. Dadurch lassen sich die Lichtkontraste, die Beleuchtungsstärke und die Farbgebung so einstellen, wie dies für den Benutzer angenehm ist, beispielsweise weiße oder gelbe hell leuchtende Zeichen auf schwach leuchtendem blauem Grund.An advantageous embodiment provides that at least one light source is arranged between the key surfaces and the base plate of the keyboard and that the key surfaces and the characters arranged on them have different levels of light permeability. This allows the light contrast, the lighting intensity and the color to be set in a way that is pleasant for the user, for example white or yellow brightly lit characters on a dimly lit blue background.

Zweckmäßigerweise ist die Lichtquelle nach Bedarf ein- und ausschaltbar, wobei auch ein Fotoelement vorgesehen sein kann, das die Beleuchtung einschaltet, wenn der Computer im Dunkeln betrieben wird.It is practical if the light source can be switched on and off as required, and a photocell can also be provided that switches the lighting on when the computer is operated in the dark.

Als Lichtquellen kommen verschiedene Möglichkeiten in Betracht, so kann vorgesehen sein, daß zwischen den Tastenunterseiten und der Bodenplatte mehrere dünne Leuchtröhren angeordnet sind, oder daß zwischen den Tastenunterseiten und der Bodenplatte eine flächige Lichtquelle angeordnet ist. Eine besonders energiesparende Ausführungs-Various options can be considered as light sources. For example, several thin fluorescent tubes can be arranged between the undersides of the keys and the base plate, or a flat light source can be arranged between the undersides of the keys and the base plate. A particularly energy-saving design

form besteht darin, daß unter der Fläche einer jeden Taste eine Leuchtdiode angeordnet ist. Viele weitere Möglichkeiten sind jedoch denkbar.form consists in having a light-emitting diode arranged under the surface of each key. However, many other possibilities are conceivable.

Eine vorteilhafte Ausführungsform sieht vor, daß die Beleuchtungsstärke regelbar ist. Auf diese Weise kann der Benutzer sie nach seinen Bedürfnissen einstellen, oder es ist möglich, die Beleuchtungsstärke mittels eines Reglers den Verhältnissen anzupassen, oder im Laufe des Betriebs zu ändern. So kann die Lichtstärke anfänglich stärker sein und dann zum Energiesparen in dem Maße vermindert werden, wie sich das Auge an die Dunkelheit gewöhnt. Dies kann auch automatisch geregelt werden.
10An advantageous embodiment provides that the lighting intensity is adjustable. In this way, the user can adjust it to his needs, or it is possible to adapt the lighting intensity to the conditions using a controller, or to change it during operation. The lighting intensity can be stronger at first and then reduced to save energy as the eye gets used to the darkness. This can also be regulated automatically.
