Description
Die vorliegende Erfindung betrifft eine Feuchtraumleuchte gemäß dem Oberbegriff des Anspruchs 1.The present invention relates to a wet room lamp according to the preamble of claim 1.
Eine Feuchtraumleuchte ist üblicherweise mit einem aus zwei Teilen bestehenden Leuchten-Gesamtgehäuse ausgebildet, wobei der eine Teil ein wannenförmiges Gehäuse ist, das Befestigungselemente zum Befestigen der Leuchte an einem Träger, z. Bsp. einer Wand oder einer Decke aufweist. Der andere Teil des Gesamtgehäuses ist durch eine zumindest teilweise transparente Abdeckung gebildet, welche durch Verschlusselemente mit dem wannenförmigen Gehäuse lösbar verbunden ist. In dem durch das wannenförmige Gehäuse und die Abdeckung gebildeten Gesamtgehäuse ist wenigstens eine Lampe angeordnet, deren im Betrieb abgestrahltes Licht durch die transparente Abdeckung zur Raumbeleuchtung abgegeben wird. Eine Leuchte dieser Art ist bspw. aus der
Entsprechend ihrer Bezeichnung kommt eine Feuchtraumleuchte insbesondere in solchen Räumen bzw. Bereichen zum Einsatz, in denen eine verhältnismäßig hohe Luftfeuchtigkeit vorliegt. Da insbesondere die elektronischen Komponenten der Leuchte vor einer zu hohen Luftfeuchtigkeit zu schützen sind, weisen Feuchtraumleuchten in der Regel eine Abdichtung zwischen dem wannenförmigen Gehäuse und der transparenten Abdeckung auf, so dass der Innenraum gegenüber der Umgebung der Leuchte abgedichtet ist. Desweiteren sollten vorzugsweise Materialien für das Leuchtengehäuse zum Einsatz kommen, welche im Hinblick auf die vorherrschenden Bedingungen an dem Einsatzort positive Eigenschaften aufweisen. Bislang wurden deshalb die wannenförmigen Gehäuse von Feuchtraumleuchten bspw. aus Polyester hergestellt. Die Abdeckung bestand üblicherweise aus Polycarbonat.According to their designation, a damp-proof luminaire is used in particular in rooms or areas in which a relatively high air humidity is present. Since, in particular, the electronic components of the luminaire are to be protected from excessively high atmospheric humidity, damp-proof luminaires generally have a seal between the trough-shaped housing and the transparent cover, so that the interior is sealed off from the surroundings of the luminaire. Furthermore, materials should preferably be used for the luminaire housing, which have positive characteristics in view of the prevailing conditions at the site. So far, therefore, the trough-shaped housing of damp-proof lights, for example, were made of polyester. The cover was usually made of polycarbonate.
Ausgehend von diesem Stand der Technik liegt der vorliegenden Erfmdung die Aufgabe zugrunde, eine neuartige Feuchtraumleuchte anzugeben, welche gegenüber bislang bekannten Lösungen weiter verbesserte Eigenschaften aufweist.Based on this prior art, the present invention is based on the object of specifying a novel moisture-proof luminaire, which has further improved properties compared to previously known solutions.
Die Aufgabe wird durch eine Feuchtraumleuchte gemäß Anspruch 1 sowie ein Verfahren zum Herstellen eines wannenförmigen Gehäuses für eine Feuchtraumleuchte gemäß Anspruch 7 gelöst. Vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der abhängigen Ansprüche.The object is achieved by a wet room lamp according to claim 1 and a method for producing a trough-shaped housing for a Moisture lamp solved according to claim 7. Advantageous developments of the invention are the subject of the dependent claims.
Die erfindungsgemäße Lösung beruht auf dem Gedanken, nunmehr das wannenförmige Gehäuse der Feuchtraumleuchte aus Polyamid zu bilden. Dieses weist besonders positive Eigenschaften auf, da es einerseits eine sehr gute chemische Resistenz aufweist und andererseits gute mechanische und thermische Eigenschaften in sich vereinigt.The solution according to the invention is based on the idea of now forming the trough-shaped housing of the moisture-proof polyamide. This has particularly positive properties, since it on the one hand has a very good chemical resistance and on the other hand combines good mechanical and thermal properties in itself.
Erfindungsgemäß wird dementsprechend eine Feuchtraumleuchte mit einem wannenförmigen Gehäuse sowie einer die Öffnung des Gehäuses abdeckenden transparenten Abdeckung vorgeschlagen, wobei das Gehäuse zumindest teilweise aus Polyamid gebildet ist.According to the invention, a damp-proof luminaire with a trough-shaped housing and a transparent cover covering the opening of the housing is accordingly proposed, wherein the housing is formed at least partially from polyamide.
Weiterhin wird ein Verfahren zum Herstellen eines wannenförmigen Gehäuses für eine Feuchtraumleuchte vorgeschlagen, wobei das Gehäuse im Spritzgussverfahren aus einem Kunststoffmaterial hergestellt wird und es sich erfindungsgemäß bei dem Material um Polyamid handelt.Furthermore, a method for producing a trough-shaped housing for a wet room lamp is proposed, wherein the housing is produced by injection molding of a plastic material and according to the invention is in the material is polyamide.
Den positiven Eigenschaften von Polyamid steht die Problematik gegenüber, dass dieses Material verhältnismäßig viel Wasser aufnimmt und ferner auch eine verhältnismäßig hohe sog. Verarbeitungsschwindung besitzt. Dies führt dazu, dass die Herstellung des Leuchtengehäuses aus reinem Polyamid mit gewissen Problemen verbunden ist.The positive properties of polyamide face the problem that this material absorbs relatively much water and also has a relatively high so-called processing shrinkage. This leads to the production of the luminaire housing made of pure polyamide associated with certain problems.
Es wurde nunmehr herausgefunden, dass diese Probleme dann vermieden werden können, wenn das Polyamid-Material mit zusätzlichen Additiven versehen wird, welche die Eigenschaften des Materials positiv beeinflussen. Bei diesen Additiven kann es sich bspw. um Glasfasern handeln, wobei der Gewichtsanteil der Glasfasern vorzugsweise im Bereich von 5% bis 20%, vorzugsweise bei etwa 15% liegt. Ferner können alternativ oder ergänzend als Additive auch Glaskugeln beigemischt werden, wobei der Gewichtsanteil der Glaskugeln vorzugsweise 20% +/- 3% beträgt. Es hat sich herausgestellt, dass in dieser Mischung das Polyamid exzellent bearbeitbar ist und insbesondere sich dieses Material dazu eignet, mit Hilfe bereits vorhandener Werkzeuge Feuchtraumleuchten-Grundwannen im Spritzgussverfahren herzustellen. Mit Hilfe der erfindungsgemäßen Lösung können dementsprechend nicht nur Feuchtraumleuchten-Grundwannen mit verbesserten Materialeigenschaften erstellt werden. Gleichzeitig ist auch sichergestellt, dass die Herstellung in der bekannten und dementsprechend kostengünstigen Weise erfolgen kann.It has now been found that these problems can be avoided if the polyamide material is provided with additional additives which positively influence the properties of the material. These additives may, for example, be glass fibers, wherein the weight fraction of the glass fibers is preferably in the range of 5% to 20%, preferably about 15%. Furthermore, alternatively or additionally, glass beads can also be admixed as additives, the weight fraction of the glass beads preferably being 20% +/- 3%. It has been found that in this mixture, the polyamide is excellently workable and in particular, this material is suitable to produce by means of existing tools damp-proof lighting base baths by injection molding. With the aid of the solution according to the invention, not only damp-proof lighting base baths with improved material properties can accordingly be created. At the same time it is also ensured that the production can be carried out in the known and therefore inexpensive manner.
Nachfolgend soll die Erfindung anhand der beiliegenden Zeichnung näher erläutert werden. Die einzige
Die Hauptbestandteile der in
Das wannenförmige Gehäuse 2 besteht nunmehr erfindungsgemäß zumindest teilweise aus Polyamid (PA). Im Vergleich zu bislang verwendeten Materialien, bspw. Polyester, weist Polyamid deutlich verbesserte Eigenschaften im Hinblick auf eine chemische Resistenz sowie auf die mechanischen und thermischen Eigenschaften auf. Die Einsatzmöglichkeiten der erfindungsgemäßen Feuchtraumleuchte können dementsprechend erweitert werden, da aufgrund der verbesserten Eigenschaften nunmehr auch Anwendungen denkbar wären, welche bei der Verwendung von Leuchtengehäusen aus Polyester bislang noch nicht möglich waren.The trough-
Polyamide sind Polymere, deren Wiederholungseinheiten als charakteristisches Merkmal die Amidgruppe besitzen. Diese kann als Kondensationsprodukt einer Carbonsäure und eines Amins aufgefasst werden. Die dabei entstehende Peptidbindung ist hydrolytisch wieder spaltbar.Polyamides are polymers whose repeating units possess the amide group as a characteristic feature. This can be understood as a condensation product of a carboxylic acid and an amine. The resulting peptide bond can be cleaved hydrolytically again.
Diese Eigenschaft führt dazu, dass Polyamid verhältnismäßig viel Wasser aufnimmt.This property causes polyamide to absorb a relatively large amount of water.
Da das Material ferner eine verhältnismäßig große so genannte Verarbeitungsschwindung besitzt, werden gemäß der vorliegenden Erfindung vorzugsweise dem Polyamid-Material Additive beigesetzt, mit deren Hilfe die oben genannten Probleme vermieden werden können.Further, since the material has a relatively large so-called processing shrinkage, according to the present invention preferably added to the polyamide material additives, by means of which the above-mentioned problems can be avoided.
Bei diesen Additiven handelt es sich insbesondere um Glasfasern und/oder Glaskugeln. So ist vorzugsweise vorgesehen, dass das Material Glasfasern beinhaltet, wobei der Gewichtsanteil dieser Glasfasern im Bereich von 5% bis 20%, vorzugsweise bei etwa 15% liegt. Alternativ oder ergänzend hierzu können dem Material auch Glaskugeln beigemischt werden, wobei vorzugsweise der Gewichtsanteil der Glaskugeln 20% +/- 3% beträgt.These additives are, in particular, glass fibers and / or glass spheres. Thus, it is preferably provided that the material includes glass fibers, wherein the weight fraction of these glass fibers in the range of 5% to 20%, preferably about 15%. Alternatively or additionally, the material may also be mixed with glass beads, wherein preferably the weight fraction of the glass beads is 20% +/- 3%.
Es hat sich nunmehr herausgestellt, dass nach Beimischung dieser Additive das Polyamid-Material deutlich besser verarbeitbar ist und insbesondere die Möglichkeit besteht, die Leuchtenwanne im Spritzgussverfahren herzustellen. Insbesondere wurde die Verarbeitbarkeit des Materials durch die Beifügung der Additive sogar soweit verbessert, dass die bislang bereits genutzten Werkzeuge zum Erstellen von Grundwannen für Feuchtraumleuchten genutzt werden können. Dies ist insbesondere im Hinblick auf die Herstellungskosten von Vorteil, da der Einsatz neuer Werkzeuge zum Herstellen der Leuchtengehäuse nicht erforderlich ist.It has now been found that, after admixing these additives, the polyamide material is significantly easier to process and, in particular, it is possible to produce the lighting pan by injection molding. In particular, the processability of the material has been improved by the addition of the additives even to the extent that the previously used tools can be used to create basements for wet room lighting. This is particularly advantageous in terms of manufacturing costs, since the use of new tools for producing the lamp housing is not required.
Selbstverständlich könnte das oben vorgestellte Material (Polyamid ggf. mit Additiven) auch bei anderen Leuchtentypen zum Einsatz kommen. Insbesondere bei Feuchtraumleuchten kommen allerdings die positiven Eigenschaften des Polyamids besonders zum tragen. Mit der vorliegenden Erfindung können deshalb hochqualitative Gehäusegrundwannen einfach und kostengünstig hergestellt werden.Of course, the material presented above (polyamide with additives if necessary) could also be used in other types of luminaires. However, especially in the case of damp-proof luminaires, the positive properties of the polyamide are particularly significant. Therefore, with the present invention, high quality casing base trays can be easily and inexpensively manufactured.
