Abstract
Description
[Technisches Gebiet][Technical field]
Die Erfindung betrifft einen Scheinwerfer, insbesondere einen LED-Scheinwerfer, umfassend ein Gehäuse, eine Vielzahl von darin aufgenommenen, auf einem gemeinen stufenförmigen Halter dicht nebeneinander und parallel zueinander angeordneten Beleuchtungseinheiten, von denen jede Beleuchtungseinheit jeweils als Lichtquelle ein LED und zur parallelen Fokusierung der vom LED ausgestrahlten Lichtstrahlen einen Reflektor aufweist, und eine Streuscheibe, nach dem Oberbegriff des Anspruchs 1.The invention relates to a headlight, in particular an LED headlamp comprising a housing, a plurality of therein recorded, close together on a common stepped holder and lighting units arranged parallel to one another, from which each lighting unit has an LED and a light source for parallel focusing of the light rays emitted by the LED has a reflector, and a diffuser, according to the preamble of claim 1.
[Stand der Technik][State of the art]
Der Erfindung liegt daher die Aufgabe zugrunde, einen Scheinwerfer zu schaffen, dessen Projektionsbild in ihrer Größe und Geometrie in einfacher Weise änderbar ist, wodurch der o.g. Nachteil vermieden ist.The invention is therefore the object based on creating a headlamp whose projection image in their size and geometry can be changed easily is what the above Disadvantage is avoided.
Die Erfindung geht vom Gedanke aus, daß als Lichtquelle statt einer einzigen Glühlampe eine Vielzahl von dicht paralle zueinander angeordneten Beleuchtungseinheiten verwendet werden, wobei jede Beleuchtungseinheit an ihrem vorderen Ende mit einer Ablenkungslinse versehen ist, das eine prismatische Strukturierung aus parallelen zylindrischen Linsen aufweist, die zumindest ein wesentliches Teil der von der Lichtquelle vorzugsweise einem LED) der Beleuchtungseinheit ausgestrahlten und durch sie hindurchgestrahlten Lichtstrahlen um einen Winkel weg von der Achse der Beleuchtungseinheit ablenkt. Wenn die allen Beleuchtungseinheiten B1 to Bn mit ihrer Strukturierung in der gelichen Drehstellung gehalten werden, so werden die allen Lichtstrahlen parallel zueinander gebündelt, wodurch ein schmalstes Projektionsbild erhalten wird., Wenn einige der Beleuchtungseinheiten z.B. B1⁓B5 um einen Winkel in eine neue Drehstellung verdreht werden, so werden die von diesen Beleuchtungseinheiten B1⁓B5 ausgestrahlten Lichtstrahlen nicht mehr parallel zu diesen aus den übrigen Beleuchtungseinheiten B6 ⁓Bn exmittierten Lichtstrahlen bleiben, sondern sie werden von diesen ausgebreitet, wodurch eine Vergrößerung des Projektionsbilds erreicht wird.The invention is based on the idea that as Light source instead of a single light bulb a variety of dense parallel lighting units used be, with each lighting unit at its front end with a deflection lens is provided, which has a prismatic structure comprises parallel cylindrical lenses that have at least one essential part of the light source, preferably an LED) radiated by the lighting unit and radiated through it Light rays at an angle away from the axis of the lighting unit distracting. If all lighting units B1 to Bn with their Structuring be kept in the same rotary position, see above the all light rays are bundled parallel to each other, whereby A narrowest projection image is obtained when some of the lighting units e.g. B1⁓B5 rotated by an angle into a new rotary position , the lighting units B1⁓B5 emitted light rays no longer parallel to these from the other lighting units B6 ⁓Bn rays of light remain, but they are spread out by these, causing an enlargement of the Projection image is reached.
