Description
Die Erfindung betrifft ein röhrenförmiges Leuchtmittel der im Oberbegriff von Anspruch 1 genannten Art. Solche Leuchtmittel werden insbesondere zur Beleuchtung von Ausstellungs- und Verkaufsflächen für Lebensmittel verwendet, damit insbesondere frische Lebensmittel, wie Wurst, Käse, Fisch, Obst und Gemüse und Backwaren, die in Ladengeschäften, wie Supermärkten, Lebensmittelgeschäften und Ähnlichem angeboten werden, für den Kunden besonders frisch und appetitlich aussehen. Dabei hat es sich bewährt, das Licht, mit dem die Waren beleuchtet werden, farblich zu nuancieren. So sehen beispielsweise Fleisch- und Wurstwaren appetitlicher aus, wenn das sie beleuchtende Licht einen Rotstich aufweist, bei Käse einen Gelbstich, bei Fisch einen Blaustich, bei Backwaren einen gelborangefarbenen Stich und bei Obst und Gemüse einen orangefarbenen Stich. Sollen die Lebensmittel mit herkömmlichen Leuchtstoffröhren beleuchtet werden, so wird das in der Leuchtstoffröhre befindliche Gasgemisch entsprechend angepasst, um die gewünschten Farbnuancen zu erzielen.The invention relates to a tubular lamp referred to in the preamble of claim 1. Such bulbs are used in particular for lighting exhibition and sales areas for food, so in particular fresh food, such as sausage, cheese, fish, fruits and vegetables and baked goods, in Shops, such as supermarkets, grocery stores and the like are offered, for the customer look especially fresh and appetizing. It has proven useful to nuance the light used to illuminate the goods. For example, meat and sausage products look more appetizing when the light illuminating them has a reddish tint, a yellowish tint in cheese, a bluish cast in fish, a yellow-orange bite in baked goods and an orange bite in fruits and vegetables. If the food is to be illuminated with conventional fluorescent tubes, the gas mixture in the fluorescent tube is adjusted accordingly in order to achieve the desired color shades.
Im Rahmen des Klimaschutzes und der Einsparung von elektrischer Energie ist es jedoch heutzutage wünschenswert, von herkömmlichen Leuchtstoffröhren abzusehen und energiesparendere Leuchtmittel zu verwenden. Zu diesem Zweck gibt es röhrenförmige Leuchtmittel, welche mit LEDs (Light Emitting Diodes) bestückt sind. Diese haben eine deutlich geringere Energieaufnahme als herkömmliche Leuchtstoffröhren.In the context of climate protection and the saving of electrical energy, however, it is now desirable to dispense with conventional fluorescent tubes and to use energy-saving lamps. For this purpose, there are tube-shaped bulbs, which are equipped with LEDs (Light Emitting Diodes). These have a significantly lower energy consumption than conventional fluorescent tubes.
Aufgabe der Erfindung ist es, ein energiesparendes röhrenförmiges Leuchtmittel zur Verfügung zu stellen, mit welchem die bewährten und gewünschten Farbnuancen herkömmlicher Leuchtstoffröhren erzielt werden können, um Lebensmittel in Ladengeschäften entsprechend frischer und appetitlicher aussehen zu lassen. Diese Aufgabe wird durch die kennzeichnenden Merkmale des Anspruches 1 gelöst, denen folgende besondere Bedeutung zukommt.The object of the invention is to provide an energy-saving tubular lamp available, with which the proven and desired color shades of conventional fluorescent tubes can be achieved to make food in shops look fresher and more appetizing. This object is achieved by the characterizing features of claim 1, which has the following special significance.
Einige der LEDs in dem röhrenförmigen Leuchtmittel emittieren farbiges Licht. Der Röhrenkörper weist zumindest in seinem lichtdurchlässigen Bereich ein milchglasartiges Material auf. Hierdurch wird das von den nicht farbigen LEDs abgegebene Licht mit dem von den Farb-LEDs emittierten Licht optisch gemischt, so dass ein in etwa gleichmäßiger farblicher Gesamteindruck des vom röhrenförmigen Leuchtmittel abgegebenen Lichtes entsteht. Die Anzahl der Farb-LEDs kann dabei so gewählt werden, dass das gleiche Lichtergebnis erzielt wird, wie mit herkömmlichen Leuchtstoffröhren. Unter milchglasartigem Material wird in diesem Zusammenhang jedes Material verstanden, welches nicht optisch klar sondern nur durchscheinend ausgebildet ist. Das Material selber kann dabei aus einem Glas, aber auch aus Kunststoff, einem Verbundwerkstoff oder einem anderen Material bestehen. Unter normalen LEDs werden die LEDs verstanden, die das nicht farbige Licht emittieren.Some of the LEDs in the tubular lamp emit colored light. The tubular body has, at least in its light-permeable area, a milk-glass-like material. As a result, the light emitted by the non-colored LEDs is optically mixed with the light emitted by the color LEDs, so that an approximately uniform overall color impression of the light emitted by the tubular light source is produced. The number of color LEDs can be chosen so that the same light result is achieved, as with conventional fluorescent tubes. Under milktglasartigem material is understood in this context, any material that is not optically clear but only translucent. The material itself may consist of a glass, but also of plastic, a composite material or another material. Normal LEDs are the LEDs that emit the non-colored light.
Selbstverständlich ist es möglich, verschiedenfarbige Farb-LEDs für die verschiedenen ausgestellten Lebensmittel vorzusehen. Somit erhält man eine Bandbreite verschiedenfarbiger röhrenförmiger Leuchtmittel, die der Bandbreite herkömmlicher Leuchtstoffröhren, die in diesem Bereich eingesetzt werden, entspricht. Selbstverständlich ist es dabei auch möglich, verschiedenfarbige Farb-LEDs in dem gleichen röhrenförmigen Leuchtmittel zu mischen, um ein gewünschtes Gesamtfarbergebnis zu erzielen. Die Anzahl der Farb-LEDs sowie die verwendete Farbe der Farb-LEDs hängen vom jeweils gewünschten Farbergebnis des röhrenförmigen Leuchtmittels ab.Of course it is possible to provide different colored color LEDs for the different foods issued. Thus, one obtains a range of different color tubular bulbs that match the bandwidth of conventional fluorescent bulbs used in this field. Of course, it is also possible to mix different colored color LEDs in the same tubular lamp to achieve a desired overall color result. The number of color LEDs and the color of the color LEDs used depend on the desired color result of the tubular light source.
Vorteilhafterweise umfasst das Leuchtmittel eine Fassung, die denen für herkömmliche Leuchtstoffröhren ähnelt, so dass das Leuchtmittel in Lampen für herkömmliche Leuchtstoffröhren Verwendung finden kann, die eine entsprechende Gegenfassung aufweisen. Somit ist es einfacher, die herkömmlichen Leuchtstoffröhren durch die erfindungsgemäßen Leuchtmittel zu ersetzen. Die Anschaffung neuer Lampen kann dann unterbleiben, was besonders wirtschaftlich ist.Advantageously, the luminous means comprises a socket which is similar to those of conventional fluorescent tubes, so that the luminous means can be used in lamps for conventional fluorescent tubes, which have a corresponding counter-frame. Thus, it is easier to replace the conventional fluorescent tubes by the lamps according to the invention. The purchase of new lamps can then be omitted, which is particularly economical.
Bevorzugterweise sind die Farb-LEDs gleichmäßig im Inneren des Leuchtmittels über die Längsachse verteilt angeordnet. Somit ergibt sich ein besonders gleichmäßiges Farbergebnis durch die optische Mischung im lichtdurchlässigen Bereich durch die Verwendung des milchglasartigen Materials.Preferably, the color LEDs are uniformly distributed in the interior of the light source over the longitudinal axis. Thus, a particularly uniform color result by the optical mixture in the translucent area by the use of the frosted glass-like material results.
Je nach gewünschtem Farbergebnis können beispielsweise 10% bis 30% der LEDs als Farb-LEDs ausgebildet sein. Die genaue Anzahl hängt wieder vom gewünschten Farbergebnis bzw. von der Intensität des farblichen Anteils des von dem Leuchtmittel emittierten Lichtes ab und ist nahezu frei wählbar.Depending on the desired color result, for example 10% to 30% of the LEDs can be designed as color LEDs. The exact number again depends on the desired color result or on the intensity of the color component of the light emitted by the light source and can be chosen almost freely.
Bevorzugterweise sind sämtliche LEDs, sowohl die weißes Licht emittierenden LEDs als auch die Farb-LEDs, auf einer gemeinsamen Platine angeordnet. Dies macht das röhrenförmige Leuchtmittel besonders einfach in der Herstellung. Die Platine kann dann mit den verschiedenfarbigen LEDs einfach bestückt werden.Preferably, all the LEDs, both the white light emitting LEDs and the color LEDs, are arranged on a common board. This makes the tubular lamp particularly easy to manufacture. The board can then be easily equipped with the different colored LEDs.
