Abstract
Description
Die Erfindung betrifft ein elektronisches Gerät mit einer Platine und druckempfindlichen Tasten, wobei die druckempfindlichen Tasten über LEDs beleuchtet sind und die LEDs über die Platine mit Strom versorgt sind.The invention relates to an electronic Device with a circuit board and pressure sensitive buttons, the pressure sensitive Keys above LEDs are illuminated and the LEDs are powered by the circuit board are.
Über LEDs beleuchtete Tastenfelder sind insbesondere bei Handys verbreitet. Jdeoch weisen auch andere elektronische Geräte, wie Funkgeräte, PDAs usw. die mobil und bei Dunkelheit verwendet werden durch LEDs beleuchtete Tastaturen auf.about Keypads illuminated with LEDs are particularly common on cell phones. However, other electronic devices, such as radios, also have PDAs etc. which are used mobile and in the dark are illuminated by LEDs Keyboards.
Je nach Hersteller bzw. Produktlinie werden unterschiedliche Farben für die beleuchteten Drucktasten gewünscht.Depending on the manufacturer or product line are different colors for the illuminated push buttons desired.
Zur Erzielung der unterschiedlichen Farben ist es bisher bekannt, entweder verschiedene Platinen mit LEDs für die jeweilige Farbe zu fertigen oder mehrere bzw. Multi-LEDs auf der Platine zu verwenden. Die unterschiedliche Platinenbestückungen je nach gewünschter Farbe erhöht aufgrund der höheren Variantenvielfalt die Herstellungskosten und bietet nicht die Flexibilität, nachträglich die Farbe ändern zu können. Werden mehrere bzw. Multi-LEDs auf den Platinen verwendet, ist eine aufwendigere Ansteuerung erforderlich und desweiteren ist der Platzbedarf erhöht. Insbesondere bei mobilen Geräten, wie Handys, ist es äußerst wichtig, die Baugröße gering zu halten, so daß schon mehrere oder größere LEDs pro Taste einen tatsächlichen Marktnachteil bedeuten.To achieve the different So far it is known to use either different boards with colors LEDs for to produce the respective color or several or multi-LEDs the board to use. The different board configurations depending on the desired Color increased due to the higher Variety of variants the manufacturing costs and does not offer the flexibility, the retrospectively Change color to can. If several or multi-LEDs are used on the boards, there is one more complex control is required and the space requirement is also increased. In particular for mobile devices, like cell phones, it is extremely important the size is small to hold so that already several or larger LEDs one actual per button Mean market disadvantage.
Der Erfindung liegt daher die Aufgabe zugrunde, eine Lösung aufzuzeigen, wie auf einfache Weise die Farbe der Beleuchtung von druckempfindlichen Tasten an einem elektronischen Gerät geändert werden kann.The invention is therefore the object underlying a solution to show how easily the color of lighting from pressure sensitive buttons on an electronic device can.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die LEDs in den Tasten oder in einem die Tasten aufnehmenden Gehäuseteil angeordnet sind und zusammen mit den Tasten bzw. dem Gehäuseteil auswechselbar sind.This object is achieved according to the invention solved, that the LEDs in the buttons or in a housing part that holds the buttons are arranged and together with the buttons or the housing part are interchangeable.
Hierdurch können LEDs je nach gewünschter Farbe in die Tasten bzw. in das Gehäuseteil eingesetzt werden und lediglich durch Auswechseln der Tasten bzw. des Gehäuseteils kann die Farbe für die Beleuchtung der Tasten geändert werden.This allows LEDs depending on the desired Color can be used in the buttons or in the housing part and only by replacing the buttons or the housing part can be the color for the lighting of the buttons changed become.
Hierdurch müssen nicht die aufwendigen Multi-LEDs bzw. müssen auch nicht mehrere LEDs auf der Platine für die Beleuchtung einer Taste plaziert werden und die Flexibilität, nachträglich die Farbe für die Beleuchtung der Tasten ändern zu können, bleibt trotzdem erhalten. Bei Handys ist es z.B. bekannt, das Cover, d.h. das Gehäuseteil, in dem die Tasten aufgenommen sind, auszutauschen, um ein neues Design zu erlangen.This eliminates the need for the complex multi-LEDs or must also not several LEDs on the board for illuminating a button be placed and the flexibility, afterwards the color for the lighting of the buttons change to be able to remain received anyway. For cell phones it is e.g. known the cover, i.e. the housing part, in which the buttons are included, to exchange a new one To achieve design.
Durch die Erfindung kann auch gleichzeitig mit dem Austauschen des Covers die Beleuchtungsfarbe für die Tasten gewechselt werden, so daß ein zur neuen Coverfarbe passendes Beleuchtungsbild für die Tasten erhalten wird.The invention can also simultaneously with when replacing the cover, the lighting color for the buttons be changed so that one for new cover color suitable lighting image for the keys is obtained.
Vorteilhafterweise sind in den Tasten bzw. in dem Gehäuseteil, welches die Tasten aufnimmt, gleichzeitig auch die Treiber für die LEDs enthalten, so daß diese lediglich durch die Platine mit Strom versorgt werden müssen.Advantageously, in the buttons or in the housing part, which holds the buttons, also the drivers for the LEDs included so that this only need to be powered by the board.
Die Kontaktierung zwischen den LEDs und der Platine erfolgt vorzugsweise über Kontaktpins, welche entweder an den Tasten, oder dem Gehäuseteil oder auch an der Platine angeordnet sein können.The contact between the LEDs and the board is preferably made via contact pins, which either on the buttons or the housing part or can also be arranged on the circuit board.
Weitere Vorteile sind in den Unteransprüchen offenbart.Further advantages are disclosed in the subclaims.
Nachfolgend wird die Erfindung anhand eines in den Figuren dargestellten Ausführungsbeispieles näher erläutert.The invention is explained below of an embodiment shown in the figures.
In den Zeichnungen zeigen:The drawings show:
In den Tasten
Sämtliche weiteren Komponenten des Handys, wie Akku, Antenne, Lautsprecher usw. sind nicht dargestellt.All other components of the cell phone, such as battery, antenna, loudspeaker etc. are not shown.
Bei der in den
Die Kontaktpins
Die Erfindung ist nicht auf das dargestellte Ausführungsbeispiel beschränkt, sondern auf sämtliche elektronische Geräte mit über LEDs beleuchteten druckempfindlichen Tasten anwendbar.The invention is not based on the illustrated embodiment limited, but on everyone electronic equipment with more than LEDs illuminated pressure sensitive buttons applicable.
