Abstract
LED-Retrofitlampe mit offenem Ringreflektor und Linse gekennzeichnet dadurch, dass der Reflektor dem Licht bei seiner nach unten weisenden Reflektion auch eine Abstrahlung in den oberen Bereich ermöglicht.LED retrofit lamp with an open ring reflector and lens characterized in that the reflector also allows the light to be emitted into the upper area when it reflects downwards.
Description
Als Ersatz für die herkömmliche Glühlampe gibt es mittlerweile verschiedene LED-Leuchtmittel. Diese sogenannten Retrofits wahren nach wie vor die Form der Glühlampe, ersetzen den Glühdraht jedoch durch die LED.As a replacement for the conventional light bulb, there are now various LED bulbs. These so-called retrofits still preserve the shape of the incandescent lamp, but replace the filament with the LED.
Die Herausforderung bei diesen neuen Haushaltsleuchtmitteln liegt insbesondere darin eine gleichmäßige, radiale Abstrahlung zu erzielen, wie einst die Glühlampe (
Diesem Problem nähern sich bereits existierende LED-Retrofits von zwei verschiedenen Richtungen, je nach Leistungsstärke der Lampe. Ein Ansatz besteht darin, einer gebündelt nach oben abstrahlende LED einen Reflektor gegenüber zu setzen, der das auftreffende Licht radial nach unten reflektiert und somit den durch den Körper entstehenden toten Bereich minimiert (
Besagte Lampen wirken durch Ihre Schwere und Ästhetik jedoch eher wie ein Kleinelektrogerät als ein Haushaltsleuchtmittel.Said lamps, however, seem more like a miniature electric appliance than a household light because of their weight and aesthetics.
Die Erfindung soll eine gleichmäßige radiale Abstrahlung sowohl im oberen als auch im unteren Bereich erzeugen (
- a) Der Reflektor ist mit einer Öffnung versehen, die ein Teil des auftreffenden Lichts nach oben durchlässt. Es handelt sich hiermit also nicht um ein spitzkonvexes, reflektierendes Bauteil, sondern um einen Ring mit winkelig angesetzter Fläche. Auf diese Weise entsteht sowohl in der oberen als auch in der unteren Hälfte ein homogenes Abstrahlbild (
4 ). - b) Bei dem auf den Reflektor gerichteten Lichtstrahl handelt es sich um Streulicht. Deswegen enthält der Korpus eine Linse.
- c) Ausschließlich der Reflektor bildet den oberen Teil der Lampe. Es entfällt die Umhüllung durch einen Glasball.
- a) The reflector is provided with an opening which allows part of the incident light to pass upwards. It is therefore not a pointed-convex, reflective component, but a ring with angled surface. In this way, a homogeneous radiation image is produced both in the upper and in the lower half (
4 ). - b) The light beam directed at the reflector is stray light. That is why the body contains a lens.
- c) Only the reflector forms the upper part of the lamp. It eliminates the wrapping by a glass ball.
Mit der Erfindung wird im Ergebnis eine gleichmäßige radiale Abstrahlung sowie eine ästhetische leichtere Wirkung eines neuartigen, energiesparenden Leuchtmittels erreicht.The invention results in a uniform radial radiation and an aesthetic lighter effect of a novel, energy-saving light source is achieved.
Die vorteilhafte Ausgestaltung der Erfindung wird anhand von
