Abstract
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 suction cleaning devices with an electrically operated brush roller and a lighting device for work area 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 movable through a suction pipe and Suction line connected to the suction cleaning device, which is movable on the floor and a suction fan as well contains a dust bag. The electrical part of the suction head is through an electrical line with the device electronics connected to the suction device. Alternatively, the suction head a rechargeable battery to operate its electrical Facilities included. In addition to the versions described for vacuum cleaners are combinations of suction heads and suction cleaning device known as the upright vacuum cleaner be designated. The vacuum cleaner is here can be swiveled to the suction head by means of a short piece of pipe connected and has one at its rear end Handle on. The electric motor of the brush roller as well as the Illumination device of the suction head are connected to the device electronics of the mains-operated vacuum cleaning device connected.
Sowohl der Saugkopf für Bodenstaubsauger als auch der Saugkopf für Upright-Sauger sind zuweilen mit einer Beleuchtungseinrichtung zur Arbeitsfeldbeleuchtung ausgerüstet. 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 cylinder vacuum cleaners and the suction head for upright vacuum cleaners are sometimes with a lighting device equipped for work area lighting. in the As part of the known measures, the lighting device an incandescent lamp or a fluorescent lamp as the illuminant on. Both versions have disadvantages. lightbulbs become hot during operation, so that most cramped installation facilities for cooling and required for safety shutdown in the event of overheating are. Furthermore, the installation space for incandescent lamps must be sufficient be temperature-resistant. Incandescent filaments in particular of incandescent lamps that are operated at mains voltage and designed for low power are extremely thin and sensitive to shock. To ensure sufficient downtime during operation To ensure in a suction head is a shock-absorbing Bracket required. That is more advantageous Use of fluorescent lamps. These are brighter and less sensitive to shocks. However, they require a large one Installation space and a correspondingly large-sized light exit window in the suction head. The control of the fluorescent lamp takes place conventionally via throttle and starter or via an electronic ballast. Both facilities 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 one of the work area lighting serving lighting device on one Improve suction head. The lighting device should bright and shock-resistant and a small one Require installation space.
Die Aufgabe wird bei einem Saugkopf für Saugreinigungsgeräte erfindungsgemäß dadurch gelöst, dass die Beleuchtungseinrichtung eine Leuchtmittelanordnung aus mehreren ultrahellen Leuchtdioden 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 task is with a suction head for suction cleaning devices solved according to the invention in that the lighting device a lamp arrangement of several has ultra-bright LEDs. Ultra bright LEDs means light emitting diodes with a light intensity of more than 1000 mCd (Milli Candela). Ultrabright light-emitting diodes are preferred with a light intensity of more than 3000 mCd. For higher luminous efficacy to achieve with directed light radiation, the light-emitting diodes, also LED chips called, in a stamped reflector with a conductive adhesive assembled. The reflector mostly forms the cathode. The Anode is contacted via a gold or aluminum wire. The arrangement is for technical handling in housed a plastic housing. The optical radiation characteristic the wired light emitting diode is through the geometry of the reflector, the shape of the plastic housing and the LED chip position inside the case established.
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 invention for the lighting device a Suction head inserted lamp arrangement can be ultra bright have white light emitting diodes that emit a very bright light submit, but sometimes as cold and uncomfortable is felt. The light color is changeable if Light-emitting diodes, the monochromatic light different Emit wavelength, so combined that a mixed color results. Teaches in a further embodiment the invention that the illuminant arrangement illuminant from ultra-bright LEDs arranged close to each other or LED chips that light in different monochromatic Give off light colors, whereby the Light means through additive color mixing of the given Light rays produce a desired light color. As part of the additive color mix becomes two or three monochromatic colors in coordinated brightness used. It is understood that the described Illuminants also with ultra-bright white LEDs can be combined in any way to create a bright light to produce 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 those from groups of light emitting diodes or Existing LED chips can have a housing with have integrated lens for focusing the light rays. The preferred in the context of the teaching of the invention ultra-bright LEDs have a beam angle between 20 and 30 ° and have a light intensity of 3000 up 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.Bright light-emitting diodes have a number of advantages on the invention when used in a Suction head can be used for suction cleaning devices. So are the light emitting diodes used according to the invention are small, vibration-proof and have a practically unlimited length Lifespan. They hardly generate any heat and are economical. The required extra low voltage can be due to the very low power of the LEDs with simple means be generated.
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 LEDs are used to illuminate the work area not in front of the suction head of a vacuum cleaning device sufficient. According to a preferred embodiment of the invention the lighting device has 5 to 10 light-emitting diodes or bulbs that are different from groups colored LEDs exist to illuminate the work area on. The light emitting diodes / illuminants useful for generating a cone of light fan-shaped aligned. The beam angle between neighboring ones Light-emitting diodes / illuminants are preferably about 5 to 10 °. The one of a plurality, easy in their orientation fan-shaped arranged ultra-bright LEDs Illuminant arrangement gives a brightness that is superior to an incandescent lamp. Due to the directional light emission the ultra-bright LEDs are unnecessary Reflectors. This enables simple and space-saving Housing the lighting device on the front a suction head for suction cleaning devices.
