Bei einer Ausgestaltung kann vorgesehen sein, dass die Kühlkörpereinrichtung eine Basisplatte aufweist, an der die Stiftkühlelemente rückseitig angeordnet sind. Die Stiftkühlelemente stehen mit der Basisplatte thermisch leitend in Verbindung, so dass an der Basisplatte auftretende Wärme an die Stiftkühlelemente übertragbar und von diesen dann an die Umgebung abgebbar ist.In one embodiment, it can be provided that the heat sink device has a base plate on which the pin cooling elements are arranged on the back side.

Bei der Ausführung der Stiftkühlelemente als geklebte Stiftelemente wird vorzugsweise ein hitzebeständiger Kleber genutzt, um die Stiftkühlelemente in der Kühlkörpereinrichtung zu befestigen. Als Kleber kann ein Wärmeleitkleber verwendet werden. Ein solcher Wärmeleitkleber kann auch genutzt werden, um die oben erläuterte Tragplatte mit den Stiftkühlelementen in der Platteneinrichtung klebend aufzunehmen. Die Stiftkühlelemente ihrerseits können unterschiedliche Querschnittsformen aufweisen, wozu runde oder eckige Querschnittsformen gehören. Die Stiftkühlelemente verfügen über einen Stiftfuß, der dann auf die Basisplatte oder in eine zugeordnete Ausnehmung in der Basisplatte angeordnet ist. In einer Ausführungsform ist der Stiftfuß von gleichem Umfang wie der darüber angeordnete Stiftkörper. Es kann aber auch vorgesehen sein, dass der Stiftfuß eine größere oder geringere Querschnittsfläche wie der darüber angeordnete Stiftkörper aufweist. Vorzugsweise ist der Stiftfuß formschlüssig in einer zugeordneten Ausnehmung in der Basisplatte aufgenommen.

The mutual distance between adjacent cooling pin elements may for example be about 9 mm to about 10 mm, preferably about 9.5 mm.

Eine Weiterbildung kann vorsehen, dass die Leiterplatte einen Kühlkern aus Metall aufweist. Die Stiftkühlelemente koppeln thermisch an den Kühlkern. In dieser oder anderen Ausführungen kann vorgesehen sein, dass die Leiterplatte an ihren Seiten so abgekantet oder umgebogen ist, dass die abgekanteten Bereiche der Leiterplatte teilweise oder ganz gleichzeitig einen Gehäuseabschnitt bilden. Beispielsweise kann eine Aluminiumleiterplatte zum Einsatz kommen, die über einen Kühlkern aus Aluminium verfügt. Die Kühlstiftelemente können an der Leiterplatte so aufgenommen sein, dass sie direkt oder indirekt an den Kühlkern thermisch koppeln. Es kann vorgesehen sein, dass zwischen den Kühlstiftelementen und dem Kühlkern ein direkter Berührungskontakt besteht.A development may provide that the printed circuit board has a cooling core made of metal. The pin cooling elements couple thermally to the cooling core. In this or other embodiments, it may be provided that the printed circuit board is bent or bent on its sides so that the folded-off regions of the printed circuit board form part or all of a housing section at the same time. For example, an aluminum printed circuit board can be used, which has a cooling core made of aluminum. The cooling pin elements may be received on the circuit board so as to thermally couple directly or indirectly to the cooling core. It can be provided that there is direct physical contact between the cooling pin elements and the cooling core.

Eine Weiterbildung sieht eine aktive Kühleinrichtung vor, die geeignet ist, einen erzwungenen Fluidstrom durch die Stiftkühlelemente zu bewirken. Die aktive Kühleinrichtung kann seitliche der Anordnung der Kühlstiftelemente angeordnet sein, vorzugsweise auf der Rückseite der Platteneinrichtung. Zur aktiven Kühlung können ein oder mehrere Lüfter eingesetzt werden. Die aktive Kühleinrichtung kann auf der Leiterplatte angeordnet sein. Vorzugsweise kommen ein oder mehrere Lüfter zum Einsatz, die geeignet sind, einen erzwungenen Fluidstrom, insbesondere Luftstrom, durch die Stiftkühlelemente mit hohem Luftvolumen und geringem Luftdruck zu erzeugen. Derartige Lüfter sind insoweit volumenoptimierte Lüfter. Ein Lüfter kann einen oder mehrere der folgenden technischen Parameter aufweisen: 700 rpm (rpm - "Rotation per Minute"), 60 Kubikmeter / h, 6,8 db und ein statischer Druck 0,44 mmH20. Es kann ein hoch optimierter "Impeller" mit "Bevelled Blade Tips" zum Einsatz kommen.A further development provides an active cooling device which is suitable for effecting a forced fluid flow through the pin cooling elements. The active cooling device may be arranged laterally of the arrangement of the cooling pin elements, preferably on the rear side of the plate device. For active cooling, one or more fans can be used. The active cooling device may be arranged on the printed circuit board. Preferably, one or more fans are used, which are suitable for generating a forced fluid flow, in particular air flow, through the pin cooling elements with high air volume and low air pressure. Such fans are so far volume-optimized fan. A fan may have one or more of the following technical parameters: 700 rpm (rpm - "rotation per minute"), 60 cubic meters / h, 6.8 db and a static pressure 0.44 mmH20. A highly optimized "Impeller" with "Bevelled Blade Tips" can be used.

Bei einer Ausgestaltung kann vorgesehen sein, dass die Anordnung von Leuchtmitteln konfiguriert ist, Licht mit einem Farbwiedergabeindex von wenigstens etwa 90, bevorzugt von wenigstens etwa 95 abzugeben. Der Farbwiedergabeindex (CRI - "Color Rendering Index") ist eine fotometrische Größe, mit der die Qualität der Farbwiedergabe von Lichtquellen gleicher korrelierter Farbtemperatur beschrieben wird. Als Referenz zur Beurteilung der Wiedergabequalität dient hierbei bis zu einer Farbtemperatur von 5000K das Licht, das von einem schwarzen Strahler der entsprechenden Farbtemperatur abgegeben wird. Über 5000K wird gegenüber einer Tageslicht ähnlichen Spektralverteilung referenziert. Der Farbwiedergabeindex ist nicht von einer bestimmten Farbtemperatur abhängig. Jede Lichtquelle, die das Spektrum eines schwarzen Strahlers gleicher (korrelierter) Farbtemperatur im Bereich der sichtbaren Wellenlänge korrekt nachbildet, erreicht einen Farbwiedergabeindex von 100. Spektralanteile außerhalb des sichtbaren Lichtes bleiben unbeachtet.In an embodiment, it can be provided that the arrangement of lighting means is configured to emit light with a color rendering index of at least about 90, preferably of at least about 95. The color rendering index (CRI) is "Color Rendering Index " a photometric quantity describing the quality of the color reproduction of light sources of the same correlated color temperature. As a reference for assessing the quality of reproduction, the light emitted by a black body of the corresponding color temperature up to a color temperature of 5000 K serves here. Over 5000K is referenced to a daylight-like spectral distribution. The color rendering index does not depend on a specific color temperature. Every light source that correctly reproduces the spectrum of a blackbody radiator with the same (correlated) color temperature in the range of the visible wavelength achieves a color rendering index of 100. Spectral components outside the visible light are ignored.

Eine Ausführungsform sieht vor, dass der Anordnung von Leuchtmitteln eine Dimmeinrichtung zugeordnet ist, mit der die Leuchtmittel analog dimmbar sind. Eine analoge Dimmung stellt eine stufenlose Regelbarkeit zur Verfügung. Die Dimmeinrichtung kann zumindest teilweise Teil der elektrischen Beschaltung der Leuchtmittel auf der Leiterplatte sein.One embodiment provides that the arrangement of lighting means is associated with a dimming device, with which the lighting means are dimmable analog. An analog dimming provides infinite controllability. The dimming device may be at least partially part of the electrical wiring of the lamps on the circuit board.

Bevorzugt sieht eine Fortbildung vor, dass der Anordnung von Leuchtmitteln eine Temperaturmesseinrichtung zugeordnet ist, mit der eine Betriebstemperatur der Leuchtmittel erfasst wird. Die Temperaturmesseinrichtung kann an eine Regeleinrichtung koppeln, die in Abhängigkeit von der erfassten Betriebstemperatur der Leuchtmittel die Spannungsversorgung für die Leuchtmittel regelt. Beispielsweise kann vorgesehen sein, die Spannung runter zu regeln, wenn ein Schwellwert für die Betriebstemperatur überschritten wird, beispielsweise zur Vermeidung einer Schädigung des Leuchtmittels. Die Temperaturmesseinrichtung und/oder die Regeleinrichtung können zumindest teilweise Teil der elektrischen Beschaltung auf der Leiterplatte sein.Preferably, a training provides that the arrangement of bulbs is associated with a temperature measuring device, with which an operating temperature of the lighting means is detected. The temperature measuring device can be coupled to a control device which regulates the voltage supply for the lighting means as a function of the detected operating temperature of the lighting means. For example, it may be provided to regulate the voltage down when a threshold value for the operating temperature is exceeded, for example to prevent damage to the lighting means. The temperature measuring device and / or the control device may be at least partially part of the electrical wiring on the circuit board.

Bei einer Ausgestaltung kann vorgesehen sein, dass Gehäuseabschnitte, die benachbart zu den Stiftkühlelementen angeordnet sind, Wärmeabführöffnungen aufweisen. Wärmeabführöffnungen können beispielsweise in den die Anordnung von Stiftkühlelementen seitlich umgebenden Gehäuseabschnitten gebildet sein. Die Wärmeabführöffnungen unterstützen die Ableitung der Wärme von der Kühlkörpereinrichtung. Die Wärmeabführöffnungen können von beliebiger Querschnittsform sein, zum Beispiel mit einer Dreiecks- oder Sechseckform gebildet sein.In one embodiment, it may be provided that housing sections, which are arranged adjacent to the pin cooling elements, have heat removal openings. Heat removal openings may be formed, for example, in the housing sections laterally surrounding the arrangement of pin cooling elements. The heat removal openings assist in dissipating the heat from the heat sink. The heat removal openings may be of any cross-sectional shape, for example formed with a triangular or hexagonal shape.

Eine Weiterbildung kann vorsehen, dass an dem Gehäuse vorderseitig ein Funktionsrahmen angeordnet ist, der konfiguriert ist, ein oder mehrere Funktionseinrichtungen am Gehäuse haltend aufzunehmen. Der Funktionsrahmen kann mit seitlich vorstehenden Gehäuseabschnitten gebildet sein. Beispielsweise verfügt der Funktionsrahmen über Einschubelemente, so dass lösbar (wechselbar) Funktionseinrichtungen am Gehäuse aufgenommen werden können. Zu den Funktionseinrichtungen kann eine Lichtstreu- oder Lichtleitplatte gehören, beispielsweise eine Linsenplatte. Es können so den Leuchtmittel wechselbare Optiken vorgeschaltet werden. Die wechselbare Lichtstreu- und / oder Lichtleiteinrichtung beeinflusst die Lichtabgabe der Beleuchtungsvorrichtung, beispielsweise zur Streulichterzeugung. Die Linsenplatte kann als eine einteilige Spritzgussplatte aus Kunststoff hergestellt sein. Die an dem Funktionsrahmen aufzunehmenden Funktionseinrichtungen sind zum Beispiel als flächige Elemente ausgeführt, die den gesamten Lichtabgabebereich der Beleuchtungsvorrichtung erfassen. Mit Hilfe der Funktionseinrichtungen kann auch eine teilweise Abschattung des Lichtabgabebereiches erfolgen. Bei der Nutzung blauer LED-Leuchten kann die hiervor angeordnete Phosphorplatte an dem Funktionsrahmen aufgenommen sein.A further development can provide that a functional frame is arranged on the front side of the housing, which is configured to receive one or more functional devices holding the housing. The functional frame may be formed with laterally projecting housing sections. For example, the functional frame has plug-in elements, so that detachable (exchangeable) functional devices can be accommodated on the housing. The functional means may include a light scattering or light guiding plate, for example a lens plate. It can be connected upstream of the light bulbs interchangeable optics. The exchangeable light scattering and / or light-guiding device influences the light output of the lighting device, for example for scattered light generation. The lens plate may be made as a one-piece plastic injection molding plate. The functional devices to be accommodated on the functional frame are designed, for example, as planar elements which detect the entire light emission range of the lighting device. With the help of the functional devices, a partial shading of the light emitting area can also take place. When using blue LED lights, the phosphor plate arranged herebefore can be accommodated on the functional frame.

Ein lästiger Effekt bei der Verwendung von bekannten Scheinwerfern mit mehr als einer Leuchte, insbesondere mehreren LED-Leuchten, sind Mehrfachschatten, die insbesondere beim Film unerwünscht sind. Der Effekt der Mehrfachschatten wird reduziert je mehr und dichter die Leuchten bzw. zugeordnete Optiken angeordnet sind. Es ist optisch vorteilhaft, eher viele Leuchten, zum Beispiel viele LED-Leuchten, mit vergleichsweise geringer Leistung zu verwenden, als wenige sehr starke. Zum Beispiel können 216 LED-Leuchten mit einer Maximalleistung von 3W zum Einsatz kommen. Diese können mit nur etwa 1.2 W betrieben werden, da die Lichtausbeute pro Watt dann wesentlich höher ist und weniger Kühlleistung erforderlich ist. Um die notwendige Kühlung zu reduzieren, ist es also vorteilhaft, die LED-Leuchten an ihrem Effizienzmaximum zu betreiben, statt mit ihrer maximal möglichen Leistung. Kommt eine Linsenplatte zum Einsatz, ist eine leichte Überlappung der Optiken vorteilhaft, um diesen Effekt noch mehr zu reduzieren. Die Verwendung einer einzigen Linsenplatte reduziert zudem die Kosten erheblich.An annoying effect when using known headlamps with more than one lamp, in particular several LED lights, are multiple shadows, which are particularly undesirable in film. The effect of the multiple shadows is reduced the more and denser the lights or associated optics are arranged. It is visually advantageous to use rather many lights, for example many LED lights, with comparatively low power, than a few very strong ones. For example, 216 LED lights with a maximum power of 3W can be used. These can be operated with only about 1.2 W, since the light output per watt is then much higher and less cooling power is required. In order to reduce the necessary cooling, it is therefore advantageous to operate the LED lights at their maximum efficiency, rather than with their maximum possible power. If a lens plate is used, a slight overlap of the optics is advantageous to reduce this effect even more. The use of a single lens plate also reduces the cost considerably.

Eine Weiterbildung sieht vor, dass an dem Gehäuse eine Befestigungseinrichtung zum lösbaren Befestigen einer Softbox gebildet ist. Mittels der Softbox kann eine Lichtformeinrichtung gebildet sein.A development provides that on the housing a fastening device for releasably securing a softbox is formed. By means of the softbox, a light shaping device can be formed.

Bei einer Ausführung umfasst die Befestigungseinrichtung Druckknöpfe, die an dem Gehäuse umlaufend gebildet sind, um die Softbox hieran lösbar zu befestigen. Bevorzug ist der Bestandteil des Druckknopfs ohne Feder am Gehäuse angeordnet, wodurch ungewünschte Geräusche vermieden sind, die die lose im Druckknopf aufgenommene Feder sonst beim Bewegen der Beleuchtungsvorrichtung verursachen könnte. Die Druckknöpfe können am Gehäuse wenigsten teilweise versenkt in einer zugeordneten Vertiefung. Dieses ermöglicht eine möglichst enge Anordnung der Beleuchtungsvorrichtung nebeneinander. Zusätzliche Streben / Spannelemente können alternativ zu oder in Kombination mit den Druckknöpfen genutzt werden, um die Softbox am Scheinwerfer zu befestigen. Endabschnitte der Streben oder der Spannelemente, die überstehen in Bezug auf das Seitenwandmaterial, insbesondere in einem bezüglich der Beleuchtungseinrichtung proximalen Randbereich der Softbox, können hierbei in zugeordnete Befestigungsausnehmungen, beispielsweise Schlitze (U-Profile), an der Beleuchtungseinrichtung eingreifen. Diese gehen über die Softbox hinaus, so dass die Enden der Elemente in ein Profil eingreifen können. Die Softbox kann alternativ oder ergänzend zu Druckknöpfen andere Befestigungsmechanismen aufweisen, beispielsweise ein U-Profil und / oder ein L-Profil, was dann in das Profil des Scheinwerfers oder eines Speedrings eingreifen kann. Das Profil kann sich längs des proximalen Randbereiches der Softbox erstrecken. Auch ein magnetischer Mechanismus mit Magneten kann ergänzend oder alternativ zur Befestigung der Softbox zum Einsatz kommen.In one embodiment, the fastener includes push buttons circumferentially formed on the housing to releasably secure the soft box thereto. Favor is the part of the push button without spring arranged on the housing, whereby unwanted noise is avoided, which could cause the loosely received in the push button spring otherwise when moving the lighting device. The push buttons can at least partially sunk in the housing in an associated recess. This allows the closest possible arrangement of the lighting device side by side. Additional struts / clamps may be used as an alternative to or in combination with the snaps to secure the softbox to the headlamp. End portions of the struts or the clamping elements which protrude with respect to the side wall material, in particular in a proximal edge region of the softbox with respect to the illumination device, can in this case engage in associated fastening recesses, for example slots (U-profiles) on the illumination device. These go beyond the softbox so that the ends of the elements can engage in a profile. The softbox may alternatively or in addition to snaps have other attachment mechanisms, such as a U-profile and / or an L-profile, which can then engage in the profile of the headlamp or a speed ring. The profile may extend along the proximal edge region of the softbox. A magnetic mechanism with magnets can also be used in addition or as an alternative to attaching the softbox.

Die Softbox ist zum Beispiel mit Seitenwänden aus flexiblem Material, beispielsweise aus einem Textil, hergestellt, die auf der Vorderseite der Beleuchtungsvorrichtung dann einen räumlichen Lichtabgabebereich ein oder mehrseitig umgeben, so dass ein Lichtformer gebildet ist.The softbox is made, for example, with sidewalls of flexible material, for example of a textile, which on the front side of the lighting device then surround a spatial light emission area on one or more sides, so that a light former is formed.

Zur Aussteifung der Seitenwände der Softbox können flexibel biegbare Stabelemente vorgesehen sein, die in zugeordnete Aufnahmetaschen eingeführt sind. Die Aufnahmetasche können entlang der Erstreckung des jeweiligen Spannelementes durchgehend oder unterbrochen am und / oder im (mehrlagigen) Material der Seitenwände gebildet sein, zum Beispiel mittels einer oder mehrerer Nähte. Die Aufnahmetasche können Schlauchabschnitte und / oder sich über die zugeordnete Seitenwand flächig erstreckende Abschnitte aufweisen. Hierbei kann vorgesehen sein, dass zu dem Gehäuse proximale Abschnitte der Stabelemente in zugeordnete Aufnahmen, zum Beispiel Schlitzaufnahmen und / oder andere Vertiefungen, an dem Gehäuse und / oder dem Funktionsrahmen angeordnet sind, insbesondere gebogene Abschnitte der Stabelemente. Eine derart ausgeführte Softbox ist nicht nur mit der hier beschriebenen Beleuchtungsvorrichtung sondern auch mit Beleuchtungsvorrichtungen anderer Art nutzbar und stellt eine flexibel einsetzbare sowie eine hohe Gebrauchsfähigkeit bereitstellende Softbox dar. Die Stabelemente bilden eine mögliche Ausführungsform von Spannelementen, die in zugeordnete Aufnahmetasche in den Seitenabschnitten der Softbox aus flexiblem Material zu deren Aussteifung aufgenommen sind. Die Spannelemente stellen bevorzugt eine Spannkraft in der Fläche der Seitenwände zur Verfügung. Es können zum Beispiel vier oder acht Seitenabschnitte gebildet sein. Die Softbox kann faltbar, sein zusammen mit den Spannelemente.
