Description

Die vorliegende Erfindung betrifft eine LED-Leuchte, insbesondere Kühlschrankleuchte oder dgl., mit mindestens einer LED, mit einer Optik für das von der mindestens einen LED abgestrahlte Licht und mit einem die Optik umgebenden lichtundurchlässigen Leuchtengehäuse.The present invention relates to an LED lamp, in particular a refrigerator lamp or the like, with at least one LED, with an optical system for the light emitted by the at least one LED and with a light-impermeable housing surrounding the optics.

Die Patentanmeldung DE19805771 offenbart die Merkmale des Oberbegriffs des Anspruchs 1.The patent application DE19805771 discloses the features of the preamble of claim 1.

Fig. 1 zeigt eine bekannte LED-Kühlschrankleuchte 101 mit einer LED 102, die auf einer Leiterplatte 103 angeordnet ist. Die LED 102 ist von einem Reflektor 104 umgeben, der das von der LED 102 abgestrahlte Licht nach vorne durch eine Gehäuseöffnung 105 eines die Leiterplatte 103 abdeckenden lichtundurchlässigen Leuchtengehäuse 106 richtet. Das Leuchtengehäuse 106 weist eine Rastaufnahme 107 auf, in der die Leiterplatte 103 aufgenommen und mittels mehrerer gehäuseseitiger Rastnasen 108 verrastet ist. Auf der der LED 102 gegenüberliegenden Leiterplattenseite ist ein Aluminium-Kühlkörper 109 zum Kühlen der LED 102 angeordnet. Der Reflektor 104 ist zwischen Leiterplatte 103 und Leuchtengehäuse 106 angeordnet und mittels einer Schraube 110 an dem Aluminium-Kühlkörper 109 angeschraubt, wodurch der Reflektor 104 und der Kühlkörper 109 an der dazwischen liegenden Leiterplatte 103 festgeklemmt sind. Zum Anschließen der LED 102 an eine Stromversorgung weist die Leiterplatte 103 einen Stecker 111 auf. Fig. 1 shows a known LED refrigerator light 101 with an LED 102 , which is arranged on a printed circuit board 103 . The LED 102 is surrounded by a reflector 104 , the light emitted by the LED 102 forward by a light Housing opening 105 of the circuit board 103 covering opaque luminaire housing 106 directed. The luminaire housing 106 has a latching receptacle 107 , in which the circuit board 103 is accommodated and latched by means of a plurality of housing-side latching lugs 108 . On the opposite side of the LED 102 printed circuit board, an aluminum heat sink 109 for cooling the LED 102 is arranged. The reflector 104 is disposed between the printed circuit board 103 and the lamp housing 106 and screwed by means of a screw 110 to the aluminum heat sink 109, whereby the reflector 104 and the heat sink 109 are clamped to the intermediate circuit board 103. To connect the LED 102 to a power supply, the printed circuit board 103 has a plug 111 .

Bei der Montage der LED-Kühlschrankleuchte 1 müssen die Leiterplatte 103, der Reflektor, welcher zuvor in einem weiteren Herstellungsschritt mit seiner Reflexionsschicht bedampft wurde, sowie der Kühlkörper 109 mittels der Schraube 110 miteinander verschraubt werden.When mounting the LED refrigerator light 1, the printed circuit board 103, the reflector, which was previously vapor-deposited in a further production step with its reflection layer, and the heat sink 109 by means of the screw 110 must be screwed together.

Demgegenüber ist es die Aufgabe der vorliegenden Erfindung, bei einer LED-Leuchte der eingangs genannten Art die Anzahl der Einzelteile zu reduzieren und die Montage zu vereinfachen.In contrast, it is the object of the present invention to reduce the number of items in an LED light of the type mentioned and to simplify the installation.

Diese Aufgabe wird durch die Merkmale des Anspruchs 1, beziehungsweise 2, gelöst.This object is solved by the features of claim 1, and 2, respectively.

Aufgrund des erfindungsgemäßen 2-Kompenenten-Kunstoffspritzteils mit angespritzter transmissiver Optik können die bisherige Reflektorbedampfung, die bisherige Schraube sowie die bisherige Montage von Reflektor, Leiterplatte, Kühlkörper und Schraube entfallen. Aufgrund der höheren Effizienz von heutzutage verfügbaren LEDs ist auch ein Kühlkörper nicht mehr erforderlich.Due to the inventive 2-component plastic injection molded part with molded transmissive optics, the previous reflector evaporation, the previous screw and the previous assembly of reflector, circuit board, heat sink and screw omitted. Due to the higher efficiency of LEDs available today, a heat sink is no longer required.

Zur zusätzlichen Strahlformung ist die Außenseite der transmissiven Optik glatt oder erfindungsgemäss mit Strukturen, wie z.B. mit Erodierstrukturen, Kissenoptiken, Zylinderlinsensegmente usw., ausgebildet.For additional beam shaping, the outside of the transmissive optic is smooth or according to the invention having structures such as e.g. with EDM structures, cushion optics, cylindrical lens segments, etc., formed.

Bevorzugt ist das 2-Kompenenten-Kunstoffspritzteil mit einer die mindestens eine LED aufweisenden Leiterplatte z.B. mittels gehäuseseitiger Rastnasen verrastet oder z.B. mittels gehäuseseitiger Führungsdome heißverstemmt. Weiterhin kann das 2-Kompenenten-Kunstoffsptritzteil - und somit die Kollimator-Optik - über Vorsprünge, die in Löcher in der Leiterplatte passgenau eingreifen, bezüglich der mindestens einen LED exakt positioniert sein.Preferably, the 2-component plastic injection molded part is provided with a printed circuit board having the at least one LED, e.g. latched by means of housing-side locking lugs or e.g. hot-staked by means of housing-side guide dome. Furthermore, the 2-component Kunstoffsptritzteil - and thus the collimator optics - via projections that fit into holes in the PCB fit exactly with respect to the at least one LED can be accurately positioned.

Die in Fig. 2 gezeigte LED-Kühlschrankleuchte 1 umfasst eine LED 2 (oder auch mehrere LEDs), die auf einer Leiterplatte 3 angeordnet ist. Vor der LED 2 ist eine transmissive Optik in Form einer Kollimator-Optik 4 oder einer optischen Linse, die als Fresnel-Linse ausgebildet ist, angeordnet, die das von der LED 2 abgestrahlte Licht richtet. Die Kollimator-Optik 4 ist zusammen mit einem die Leiterplatte 3 abdeckenden lichtundurchlässigen Leuchtengehäuse 5 durch ein 2-Kompenenten-Kunststoffspritzteil 6 gebildet. Die Kollimator-Optik 4 ist aus transparentem Kunststoff und das Leuchtengehäuse 5 aus lichtundurchlässigem Kunststoff gebildet.In the Fig. 2 shown LED refrigerator light 1 comprises an LED 2 (or even several LEDs), which is arranged on a printed circuit board 3 . In front of the LED 2 is a transmissive optics in the form of a collimator optics 4 or an optical lens, which is designed as a Fresnel lens, arranged, which directs the light emitted by the LED 2 light. The collimator optic 4 is formed together with a PCB 3 covering opaque luminaire housing 5 by a 2-component plastic injection molded part 6 . The collimator optics 4 is made of transparent plastic and the lamp housing 5 is formed of opaque plastic.

Die Außenseite der Kollimator-Optik 4 kann glatt sein oder, nach der Erfindung wie in Fig. 2 gezeigt, Strukturen 7, z.B. Erodierstrukturen, Kissenoptiken oder Zylinderlinsensegmente, zur zusätzlichen Strahlformung aufweisen.The outside of the collimator optics 4 may be smooth or, according to the invention as in Fig. 2 have structures 7 , for example erosion structures, cushion optics or cylindrical lens segments, for additional beam shaping.

Das Kunststoffspritzteil 6 greift mit Vorsprüngen (Führungsdome) 8, die am Leuchtengehäuse 5 vorgesehen sind, in Löcher der Leiterplatte 3 passgenau ein, wodurch die Kollimator-Optik 4 und die LED 2 zueinander exakt positioniert sind. Die Leiterplatte 3 liegt auf Absätzen der Vorsprünge 8 auf, wobei die Vorsprünge 8 zur Befestigung der Leiterplatte 3 heißverstemmt sind. Alternativ können - analog zu Fig. 1 - am Leuchtengehäuse 5 Rastnasen angespritzt sein, um die Leiterplatte 3 am Kunststoffspritzteil 6 zu verrasten. Zum Anschließen der LED 2 an eine Stromversorgung weist die Leiterplatte 3 einen Stecker 9 auf.The plastic injection-molded part 6 engages with projections (guide dome) 8 , which are provided on the lamp housing 5, in holes of the printed circuit board 3 with an exact fit, whereby the collimator optics 4 and the LED 2 are exactly positioned relative to each other. The printed circuit board 3 rests on heels of the projections 8, the projections 8 being hot-spliced for fastening the printed circuit board 3. Alternatively - analogous to Fig. 1 - Be molded onto the lamp housing 5 locking lugs to lock the circuit board 3 on the plastic injection molded part 6. To connect the LED 2 to a power supply, the circuit board 3 has a plug 9 .

Von der LED-Kühlschrankleuchte 1 der Fig. 2 unterscheidet sich die in Fig. 3 gezeigte LED-Kühlschrankleuchte 21 lediglich dadurch, dass hier die transmissive Optik, die zusammen mit dem die Leiterplatte 3 abdeckenden lichtundurchlässigen Leuchtengehäuse 5 durch ein 2-Kompenenten-Kunststoffspritzteil 6 gebildet ist, als eine Diffusor-Optik 22 in Form einer lichtstreuenden Diffusorscheibe gebildet ist und dass zwischen der LED 2 und der Diffusorscheibe 22 eine separate transmissive Kollimator-Optik 23 oder eine separate optische Linse (z.B. Fresnel-Linse) an der Leiterplatte 3 heißverstemmt oder verclipst ist. Zur weiteren Strahlformung weist die Diffusorscheibe 22 innenseitige Optikstrukturen (z.B. Kissenoptiken, Zylinderlinsen, Erodierstruktur,...) 24 auf. Zusätzlich oder alternativ kann die Diffusorscheibe 22 auch außenseitige Optikstrukturen (nicht gezeigt) aufweisen. Die Diffusorscheibe 22 kann in dem 2-Kompenenten-Kunststoffspritzteil 6 z.B. als milchige Kunststoffkomponente ausgebildet sein. Die Außenseite der Kollimator-Optik 23 kann glatt sein oder, wie in Fig. 3 gezeigt, Optikstrukturen 25, z.B. Erodierstrukturen, Kissenoptiken oder Zylinderlinsensegmente, zur zusätzlichen Strahlformung und Lenkung aufweisen. Im Unterschied zur LED-Kühlschrankleuchte 1 weist die LED-Kühlschrankleuchte 21 somit mindestens zwei optisch wirksame Flächen, nämlich die innenseitige Optikstrukturen 24 der Diffusorscheibe 22 und die Optikstrukturen 25 der Kollimator-Optik 23, auf, um das von der LED 2 abgestrahlte Licht, falls erforderlich, noch besser zu homogenisieren.From the LED fridge light 1 of the Fig. 2 is different in the Fig. 3 shown LED refrigerator light 21 only in that here the transmissive optics, which is formed together with the circuit board 3 covering the opaque luminaire housing 5 by a 2-component plastic injection molded part 6, as a diffuser optics 22 in the form of a light scattering diffuser disc and a separate transmissive collimator optic 23 or a separate optical lens (eg Fresnel lens) on the printed circuit board 3 is hot-spliced or clipped between the LED 2 and the diffuser disk 22. For further beam shaping, the diffuser disk 22 has inner-side optical structures (eg cushion optics, cylindrical lenses, erosion structure, etc.) 24 . Additionally or alternatively, the diffuser disk 22 may also have exterior optics structures (not shown). The diffuser disk 22 may be formed in the 2-component plastic injection-molded part 6, for example as a milky plastic component. The outside of the collimator optics 23 may be smooth or, as in FIG Fig. 3 Shown are optical structures 25 , eg erosion structures, cushion optics or cylindrical lens segments, for additional beam shaping and steering. In contrast to the LED refrigerator light 1, the LED refrigerator light 21 thus has at least two optically active surfaces, namely the inside optical structures 24 of the diffuser disk 22 and the optical structures 25 the collimator optics 23, in order to even better homogenize the light emitted by the LED 2, if necessary.
