Description

Die Erfindung betrifft einen Saugkopf für Saugreinigungsgeräte mit einer elektrisch betriebenen Bürstenwalze und einer Beleuchtungseinrichtung zur Arbeitsfeldbeleuchtung.The invention relates to a suction head for Saugreinigungsgeräte with an electrically operated brush roller and a lighting device for working field lighting.

Der Saugkopf ist durch ein Saugrohr und eine bewegliche Saugleitung mit dem Saugreinigungsgerät verbunden, welches auf dem Boden verfahrbar ist und ein Sauggebläse sowie einen Staubbeutel enthält. Der elektrische Teil des Saugkopfes ist durch eine Elektroleitung mit der Geräteelektrik des Sauggerätes verbunden. Alternativ kann der Saugkopf einen wiederaufladbaren Akku zum Betrieb seiner elektrischen Einrichtungen enthalten. Neben den beschriebenen Ausführungen für Bodenstaubsauger sind Kombinationen aus Saugkopf und Saugreinigungsgerät bekannt, die als Upright-Sauger bezeichnet werden. Das Saugreinigungsgerät ist hier durch ein kurzes Rohrstück schwenkbeweglich an den Saugkopf angeschlossen und weist an seinem rückwärtigen Ende einen Handgriff auf. Der Elektromotor der Bürstenwalze sowie die Beleuchtungseinrichtung des Saugkopfes sind an die Geräteelektrik des netzbetriebenen Saugreinigungsgerätes angeschlossen.The suction head is connected by a suction pipe and a movable suction line with the vacuum cleaning device, which is movable on the ground and contains a suction fan and a dust bag. The electrical part of the suction head is connected by an electric line to the electrical equipment of the suction device. Alternatively, the suction head may include a rechargeable battery for operating its electrical equipment. In addition to the described designs for vacuum cleaner, combinations of suction head and vacuum cleaning device are known, which are referred to as upright vacuum cleaner. The vacuum cleaning device is connected here by a short pipe piece pivotally connected to the suction head and has at its rear end to a handle. The electric motor of the brush roller and the lighting device of the suction head are connected to the electrical equipment of the mains operated vacuum cleaning device.

Sowohl der Saugkopf für Bodenstaubsauger als auch der Saugkopf für Upright-Sauger sind zuweilen mit einer Beleuchtungseinrichtung zur Arbeitsfeldbeleuchtung ausgerüstet. Ein derartiger Saugkopf ist aus dem Dokument US 5 467 501 bekannt. Im Rahmen der bekannten Maßnahmen weist die Beleuchtungseinrichtung als Leuchtmittel eine Glühlampe oder eine Leuchtstofflampe auf. Beide Ausführungen haben Nachteile. Glühlampen werden im Betrieb heiß, so dass bei den zumeist beengten Einbauverhältnissen Einrichtungen zur Kühlung und zur Sicherheitsabschaltung bei Überhitzung erforderlich sind. Ferner muss der Einbauraum für Glühlampen ausreichend temperaturbeständig ausgebildet sein. Glühwendeln insbesondere von Glühlampen, die bei Netzspannung betrieben werden und für kleine Leistungen ausgelegt sind, sind extrem dünn und stoßempfindlich. Um ausreichende Standzeiten beim Betrieb in einem Saugkopf zu gewährleisten, ist eine stoßgedämpfte Halterung erforderlich. Vorteilhafter ist die Verwendung von Leuchtstofflampen. Diese sind lichtstärker und stoßunempfindlicher. Sie erfordern jedoch einen großen Einbauraum und ein entsprechend großdimensioniertes Lichtaustrittfenster im Saugkopf. Die Ansteuerung der Leuchtstofflampe erfolgt konventionell über Drossel und Starter oder über ein elektronisches Vorschaltgerät. Beide Einrichtungen sind konstruktiv aufwendig.Both the suction head for vacuum cleaner and the suction head for Upright vacuum cleaner are sometimes equipped with a lighting device for working area lighting. Such a suction head is from the document US 5,467,501 known. As part of the known measures, the lighting device as a light bulb on an incandescent lamp or a fluorescent lamp. Both versions have disadvantages. Incandescent lamps are hot during operation, so most of them are cramped installation conditions Cooling equipment and safety shutdown in case of overheating are required. Furthermore, the installation space for incandescent lamps must be sufficiently temperature resistant. Incandescent filaments, in particular incandescent lamps, which are operated at mains voltage and are designed for low powers, are extremely thin and shock-sensitive. In order to ensure sufficient service life when operating in a suction head, a shock-damped bracket is required. More advantageous is the use of fluorescent lamps. These are brighter and less sensitive to impact. However, they require a large installation space and a correspondingly large-sized Lichtaustrittfenster in the suction head. The control of the fluorescent lamp is done conventionally throttle and starters or via an electronic ballast. Both devices are structurally complex.

Der Erfindung liegt die Aufgabe zugrunde, eine der Arbeitsfeldbeleuchtung dienende Beleuchtungseinrichtung an einem Saugkopf zu verbessern. Die Beleuchtungseinrichtung soll lichtstark und stoßunempfindlich sein und einen kleinen Einbauraum erfordern.The invention has for its object to improve a working field lighting serving lighting device on a suction head. The lighting device should be bright and insensitive to impact and require a small installation space.

Die Aufgabe wird bei einem Saugkopf für Saugreinigungsgeräte erfindungsgemäß dadurch gelöst, dass die Beleuchtungseinrichtung eine Leuchtmittelanordnung aus mehreren ultrahellen Leuchtdioden, wie sie z.B. aus US 5 561 346 bekannt sind, aufweist. Ultrahelle Leuchtdioden meint Leuchtdioden mit einer Lichtstärke von mehr als 1000 mCd (Milli Candela). Bevorzugt sind ultrahelle Leuchtdioden mit einer Lichtstärke von mehr 3000 mCd. Um höhere Lichtausbeuten bei gerichteter Lichtabstrahlung zu erreichen, werden die lichtemittierenden Dioden, auch LED-Chips genannt, in einem gestanzten Reflektor mit einem Leitkleber montiert. Der Reflektor bildet zumeist die Kathode. Die Anode wird über einen Gold- oder Aluminiumdraht kontaktiert. Die Anordnung ist zur technischen Handhabung in einen Kunststoffgehäuse untergebracht. Die optische Abstrahlcharakteristik der bedrahteten Leuchtdiode wird durch die Geometrie des Reflektors, die Form des Kunststoffgehäuses und die LED-Chipposition innerhalb des Gehäuses festgelegt.The object is achieved in a suction head for Saugreinigungsgeräte according to the invention that the lighting device is a lighting arrangement of several ultra-bright LEDs, as for example US 5 561 346 are known. Ultra-bright light-emitting diodes means light-emitting diodes with a light intensity of more than 1000 mCd (milli candela). Preference is given to ultra-bright LEDs with a light intensity of more than 3000 mCd. To achieve higher luminous efficiencies with directional light emission, The light-emitting diodes, also called LED chips, mounted in a stamped reflector with a conductive adhesive. The reflector usually forms the cathode. The anode is contacted via a gold or aluminum wire. The arrangement is housed for technical handling in a plastic housing. The optical radiation characteristic of the wired LED is determined by the geometry of the reflector, the shape of the plastic housing and the LED Chipposition within the housing.

Die erfindungsgemäß für die Beleuchtungseinrichtung eines Saugkopfes eingesetzte Leuchtmittelanordnung kann ultrahelle weiße Leuchtdioden aufweisen, die ein sehr helles Licht abgeben, das manchmal aber als kalt und wenig wohnlich empfunden wird. Die Lichtfarbe ist veränderbar, wenn Leuchtdioden, die monochromatisches Licht unterschiedlicher Wellenlänge abgeben, so miteinander kombiniert werden, dass eine Mischfarbe resultiert. In weiterer Ausgestaltung lehrt die Erfindung, dass die Leuchtmittelanordnung Leuchtmittel aus dicht nebeneinander angeordneten ultrahellen Leuchtdioden oder LED-Chips, die Licht in unterschiedlichen monochromatischen Lichtfarben abgeben, aufweist, wobei die Lichtmittel durch additive Farbmischung der abgegebenen Lichtstrahlen eine gewünschte Lichtfarbe ergeben. Im Rahmen der additiven Farbmischung werden zwei oder drei monochromatische Farben in aufeinander abgestimmter Helligkeit eingesetzt. Es versteht sich, dass die beschriebenen Leuchtmittel auch mit ultrahellen weißen Leuchtdioden beliebig kombiniert werden können, um ein helles Licht in gewünschter Lichtfarbe zu erzeugen.The illuminant arrangement used according to the invention for the illumination device of a suction head can have ultra-bright white light-emitting diodes, which emit a very bright light, which is sometimes perceived as cold and uninhabitable. The light color is changeable when light emitting diodes which emit monochromatic light of different wavelengths are combined with one another in such a way that a mixed color results. In a further refinement, the invention teaches that the illuminant arrangement comprises illuminants made of closely spaced ultra-bright light-emitting diodes or LED chips which emit light in different monochromatic light colors, wherein the light means produce a desired light color through additive color mixing of the emitted light beams. In the context of additive color mixing, two or three monochromatic colors are used in coordinated brightness. It goes without saying that the illuminants described can also be combined as desired with ultra-bright white light-emitting diodes in order to produce a bright light in the desired light color.

Die Leuchtdioden oder die aus Gruppen von Leuchtdioden oder LED-Chips bestehenden Leuchtmittel können ein Gehäuse mit integrierter Linse zur Bündelung der Lichtstrahlen aufweisen. Die im Rahmen der erfindungsgemäßen Lehre bevorzugten ultrahellen Leuchtdioden haben einen Abstrahlwinkel zwischen 20 und 30° und besitzen eine Lichtstärke von 3000 bis 5000 mCd.The light-emitting diodes or the bulbs consisting of groups of light-emitting diodes or LED chips can have a housing with integrated lens for focusing the light beams. The preferred within the scope of the teaching of the invention ultra-bright LEDs have a beam angle between 20 and 30 ° and have a light intensity of 3000 to 5000 mCd.

Lichtstarke Leuchtdioden weisen eine Reihe von Vorteilen auf, die erfindungsgemäß bei der Anwendung in einem Saugkopf für Saugreinigungsgeräte genutzt werden. So sind die erfindungsgemäß eingesetzten Leuchtdioden klein, erschütterungsfest und haben eine praktisch unbegrenzt lange Lebensdauer. Sie entwickeln kaum Wärme und sind sparsam. Die erforderliche Kleinspannung kann aufgrund der sehr geringen Leistungen der Leuchtdioden mit einfachen Mitteln erzeugt werden.High-intensity light-emitting diodes have a number of advantages, which according to the invention are used when used in a suction head for vacuum cleaning devices. Thus, the light-emitting diodes used in the invention are small, vibration resistant and have a virtually unlimited long life. They hardly develop heat and are economical. The required low voltage can be generated by simple means due to the very low power of the LEDs.

Einzelne Leuchtdioden sind zur Ausleuchtung des Arbeitsfeldes vor dem Saugkopf eines Saugreinigungsgerätes nicht ausreichend. Gemäß einer bevorzugten Ausführung der Erfindung weist die Beleuchtungseinrichtung 5 bis 10 Leuchtdioden oder Leuchtmittel, die aus Gruppen verschieden farbiger Leuchtdioden bestehen, zur Ausleuchtung des Arbeitsfeldes auf. Dabei sind die Leuchtdioden/Leuchtmittel zweckmäßig zur Erzeugung eines Lichtkegels fächerförmig ausgerichtet. Die Abstrahlwinkel zwischen benachbarten Leuchtdioden/Leuchtmittel betragen vorzugsweise etwa 5 bis 10°. Die aus einer Mehrzahl, in ihrer Ausrichtung leicht fächerförmig angeordneten ultrahellen Leuchtdioden bestehende Leuchtmittelanordnung ergibt eine Helligkeit, die einer Glühlampe überlegen ist. Durch die gerichtete Lichtabstrahlung der ultrahellen Leuchtdioden erübrigen sich Reflektoren. Das ermöglicht eine einfache und platzsparende Unterbringung der Beleuchtungseinrichtung an der Frontseite eines Saugkopfes für Saugeinigungsgeräte.Individual light emitting diodes are not sufficient to illuminate the working field in front of the suction head of a vacuum cleaning device. According to a preferred embodiment of the invention, the illumination device has 5 to 10 light-emitting diodes or light-emitting means, which consist of groups of differently colored light-emitting diodes, for illuminating the working field. In this case, the light-emitting diodes / lighting means are expediently oriented in a fan-shaped manner for generating a light cone. The emission angle between adjacent light-emitting diodes / lamps is preferably about 5 to 10 °. The consisting of a plurality, in their orientation slightly fan-shaped arranged ultra-bright light-emitting diodes Illuminant arrangement results in a brightness that is superior to a light bulb. Due to the directional light emission of the ultra-bright LEDs, reflectors are unnecessary. This allows a simple and space-saving placement of the lighting device on the front of a suction head for suction cleaning equipment.
