Abstract
Description
Die Erfindung bezieht sich auf eine Beleuchtungsvorrichtung, und im Spezielleren auf eine wasserbeständige Beleuchtungsvorrichtung.The The invention relates to a lighting device, and in More special on a water resistant Lighting device.
Eine herkömmliche wasserbeständige Beleuchtungsvorrichtung für maschinelle Anlagen umfasst eine Leuchtstofflampe. Infolge ihrer hohen Wärmeentwicklung und ihres hohen Energieverbrauchs hat eine Leuchtstofflampe jedoch eine kürzere Nutzungsdauer, und das Licht, das von der Leuchtstofflampe erzeugt wird, wird nicht wirksam konzentriert.A conventional water resistant Lighting device for Mechanical equipment includes a fluorescent lamp. As a result of her high heat development and its high energy consumption, however, has a fluorescent lamp a shorter one Service life, and the light generated by the fluorescent lamp is not effectively concentrated.
Deshalb besteht die Aufgabe der vorliegenden Erfindung darin, eine wasserbeständige Beleuchtungsvorrichtung bereitzustellen, die eine bessere Wärmeableitungsfähigkeit und eine längere Nutzungsdauer hat und eine Beleuchtung mit großer Helligkeit erzielen kann.Therefore The object of the present invention is to provide a water-resistant lighting device to provide better heat dissipation capability and a longer useful life and can achieve high brightness lighting.
Nach
der vorliegenden Erfindung umfasst eine Beleuchtungsvorrichtung:
ein
aus einem wärmeleitenden
Material hergestelltes rohrförmiges
Gehäuse,
das mit einem Aufnahmeraum ausgebildet ist und ein offenes vorderes
Ende und ein dem vorderen Ende in einer axialen Richtung des Gehäuses entgegengesetztes
geschlossenes hinteres Ende aufweist;
ein im Aufnahmeraum im
Gehäuse
angeordnetes Beleuchtungsmittel, wobei das Beleuchtungsmittel umfasst:
eine
wärmeableitende
Platte, die im Gehäuse
platziert und angrenzend an das vordere Ende des Gehäuses angeordnet
ist, wobei die wärmeableitende Platte
eine Montagefläche
aufweist, die dem vorderen Ende des Gehäuses zugewandt ist,
eine
Leiterplatte in Wärmekontakt
mit der Montagefläche
der wärmeableitenden
Platte,
mehrere Leuchteinheiten, wovon jede eine an der Leiterplatte
angebrachte Leuchtdiode aufweist, und ein Kondensorglied, das an
der Leiterplatte angebracht und um die Leuchtdiode herum angeordnet
ist, und
eine fest im Gehäuse
angeordnete Ansteuereinheit, die elektrisch mit der Leiterplatte
verbunden und dazu ausgelegt ist, an eine externe Stromquelle angeschlossen
zu werden, um die Leuchtdioden der Leuchteinheiten zu aktivieren;
eine
transparente Platte, die im Gehäuse
und vor den Leuchteinheiten angeordnet ist;
eine ringförmige Kappe,
die am vorderen Ende des Gehäuses
angebracht ist und sich in den Aufnahmeraum erstreckt; und
einen
Dichtungsring, der zwischen dem Gehäuse, der transparenten Platte
und der Kappe angeordnet ist und daran anliegt, um eine flüssigkeitsdichte
Abdichtung zwischen diesen herzustellen.According to the present invention, a lighting device comprises:
a tubular housing made of a thermally conductive material, which is formed with a receiving space and having an open front end and a closed rear end opposite the front end in an axial direction of the housing;
a lighting means disposed in the housing in the receiving space, the lighting means comprising:
a heat-dissipating plate placed in the housing and disposed adjacent to the front end of the housing, the heat-dissipating plate having a mounting surface facing the front end of the housing,
a printed circuit board in thermal contact with the mounting surface of the heat dissipating plate,
a plurality of light units, each having a light emitting diode mounted on the printed circuit board, and a condenser member mounted on the printed circuit board and disposed around the light emitting diode, and
a fixed in the housing drive unit, which is electrically connected to the circuit board and adapted to be connected to an external power source to activate the light emitting diodes of the light units;
a transparent plate disposed in the housing and in front of the lighting units;
an annular cap attached to the front end of the housing and extending into the receiving space; and
a seal ring disposed between and in contact with the housing, the transparent plate and the cap to provide a fluid tight seal therebetween.
Weitere Merkmale und Vorteile der vorliegenden Erfindung gehen aus der folgenden ausführlichen Beschreibung der bevorzugten Ausführungsform mit Bezug auf die beigefügten Zeichnungen hervor:Further Features and advantages of the present invention will become apparent from the following detailed Description of the Preferred Embodiment With Reference to FIGS attached Drawings:

Bei folgenden handelt es sich um einige der Vorteile, die der Beleuchtungsvorrichtung der vorliegenden Erfindung zugesprochen werden:
- 1.
Aufgrund des Vorhandenseins der wärmeableitenden Platte
2 und des wärmeleitenden Gehäuses1 kann Wärme abgeleitet werden, die von den Leuchtdioden51 erzeugt wird. - 2. Aufgrund des Einsatzes von Hochleistungsleuchtdioden
51 mit einer Nutzdauer von ca. 100.000 Stunden hat die Beleuchtungsvorrichtung dieser Erfindung im Vergleich zur zuvor erwähnten herkömmlichen Beleuchtungsvorrichtung eine längere Nutzungsdauer. - 3. Aufgrund des Vorhandenseins der Sammellinsen
522 und der Gitterplatte53 kann die Beleuchtungsvorrichtung eine Beleuchtung mit großer Helligkeit erzielen.
- 1. Due to the presence of the heat-dissipating plate
2 and the heat-conducting housing1 Heat can be dissipated by the light emitting diodes51 is produced. - 2. Due to the use of high power light emitting diodes
51 With a useful life of about 100,000 hours, the lighting device of this invention has a longer service life compared with the aforementioned conventional lighting device. - 3. Due to the presence of the collecting lenses
522 and the grid plate53 For example, the lighting device can achieve high brightness lighting.
