Dadurch kann gewährleistet werden, dass sich die bei der Installation definierten Abstände in Längsrichtung zwischen der Leuchtenabdeckung und dem Befestigungsprofil ebenfalls symmetrisch verändern, so dass ein homogener Gesamteindruck weiterhin bereitgestellt werden kann. Vorzugsweise ist zur Erhöhung der Reibung in den Reibungsbereichen zumindest ein doppelseitiges Klebeband zwischen dem Befestigungsprofil und der In other words, the present invention proposes to connect the luminaire cover in these areas so firmly with the fastening profile by at least two opposing friction areas that essentially the entire relative movement of the fastening profile for luminaire coverage can only take place outside of these friction areas. It can thus be ensured that the distances defined in the longitudinal direction between the lamp cover and the fastening profile also change symmetrically, so that a homogeneous overall impression can continue to be provided. Preferably, to increase the friction in the friction areas, at least one double-sided adhesive tape between the fastening profile and the
Leuchtenanordnung angeordnet. Ein solches doppelseitiges Klebeband haftet dann einerseits am Befestigungsprofil (vorzugsweise eine Lichtbandschiene aus Aluminium) und an der Leuchtenabdeckung. Die Reibungsbereiche sind dabei vorzugsweise an Kontaktflächen im Bereich der Rast- oder Klemmmitteln vorgesehen. Luminaire arrangement arranged. Such a double-sided adhesive tape then adheres on the one hand to the fastening profile (preferably an aluminum roof rail) and to the luminaire cover.

Ein solches einseitiges Klebeband kann entweder am Befestigungsprofil oder an der Leuchtenabdeckung oder an beiden angeordnet werden. Durch die Verwendung eines solchen einseitigen Klebebands besteht die Möglichkeit, eine bereits montierte Preferably, in order to increase the friction in the friction regions, at least one single-sided adhesive tape is arranged, which has on its non-adhesive side an anti-slip coating (for example by a knob-like structure). Such a single-sided adhesive tape can be arranged either on the mounting profile or on the lamp cover or both.

Eine solche Reibungsfolie, die an beiden Seiten Anti-Rutsch- Beschichtungen oder ähnlich wirkende Oberflächenstrukturen aufweisen, können zwischen dem Befestigungsprofil und der Leuchtenabdeckung eingeklemmt werden, insbesondere zwischen den Rast- oder Klemmmitteln der Leuchtenabdeckung und den Schenkeln des vorzugsweise u-förmigen Befestigungsprofils. Durch die erhöhte Reibung wird in diesen Reibungsbereichen eine Art Fixierung bereitgestellt, in dem keine wesentliche Relativbewegung mehr zwischen der Leuchtenabdeckung und dem Befestigungsprofil erfolgen kann, so dass eine Längenausdehnung von diesen Preferably, in order to increase the friction in the friction regions, at least one friction film is arranged between the fastening profile and the lamp cover. Such a friction film having anti-skid coatings or similar surface structures on both sides can be clamped between the fastening profile and the lamp cover, in particular between the latching or clamping means of the lamp cover and the legs of the preferably U-shaped fastening profile. Due to the increased friction, a kind of fixation is provided in these friction areas, in which no significant relative movement can take place between the lamp cover and the fastening profile, so that a longitudinal extension of these

Die oben genannten Mittel zur Erhöhung der Reibung in den Reibungsbereichen können dabei werksseitig für den Kunden bereitgestellt werden, wobei insbesondere bei der Verwendung separater Elemente (insbesondere doppelseitige Klebebänder, einseitige Klebebänder mit Anti-Rutsch-Beschichtung, Reibungsfolien, etc.) können diese auch kundenseitig montiert und somit einbauspezifisch vorgesehen werden. Insbesondere durch das kundenseitige Anbringen der separaten Elemente zur The above-mentioned means for increasing the friction in the friction regions can be provided at the factory for the customer, in particular when using separate elements (especially double-sided adhesive tapes, one-sided adhesive tapes with anti-slip coating, friction films, etc.), these can also be provided by the customer mounted and thus provided specific to the installation. In particular, by the customer attaching the separate elements to

Zeitpunkt nachjustiert werden kann, um den optischen Gesamteindruck der Time can be readjusted to the overall visual impression of
Lichtbandleuchte bzw. des Lichtbandsystems zu optimieren. Continuous lighting or the lighting system to optimize.
Vorteilhafterweise erstrecken sich die Rast- oder Klemmmittel über die gesamte Längsachse der Leuchtenabdeckung. Ferner ist es bevorzugt, dass die Rast- oder Klemmmittel im Längsquerschnitt hakenförmig ausgebildet sind. Dabei ist es bevorzugt, dass die Reibungsbereiche an den Rast- oder Klemmmitteln angeordnet sind, also vorzugsweise an den hakenförmigen Rast- oder Klemmmitteln. Advantageously, the latching or clamping means extend over the entire longitudinal axis of the lamp cover. Furthermore, it is preferred that the latching or clamping means are hook-shaped in the longitudinal cross-section. It is preferred that the friction regions are arranged on the latching or clamping means, that is preferably on the hook-shaped latching or clamping means.
Wie bereits ausgeführt, ist es bevorzugt, dass die sich gegenüberliegenden As already stated, it is preferred that the opposing
Reibungsbereiche in einem zentralen Bereich bezüglich der Längsachse der Friction areas in a central region with respect to the longitudinal axis of
Leuchtenabdeckung angeordnet sind, um eine im Wesentlichen symmetrische Luminaire covers are arranged to be a substantially symmetrical
Längenausdehnung der Leuchtenabdeckung bereitstellen zu können. To be able to provide longitudinal expansion of the luminaire cover.
Vorteilhafterweise sind mehrere an gegenüberliegenden Längsseiten der Advantageously, several at opposite longitudinal sides of
Leuchtenabdeckung angeordnete Reibungsbereiche vorgesehen, wobei die sich jeweils gegenüberliegenden Reibungsbereiche gleichförmig über die Längsachse in der Leuchtenabdeckung verteilt sind.

Abwinklungen vorgesehen sind, in denen sich entsprechend schräge Stoßbereiche von Leuchtenabdeckungen ergeben können. In diesen Bereichen sind die Angled portions are provided, in which correspondingly oblique joint areas of lamp covers can result. In these areas are the
Leuchtenabdeckungen quasi auf Gehrung zugeschnitten, so dass sich in diesen Bereichen ein Verschieben der Position der Leuchtenabdeckungen zueinander optisch besonders nachteilig auswirken würde. Bei einer derartigen Ausgestaltung ist es wünschenswert, dass die Stoßbereiche sich nicht aufgrund der Wärmeausdehnung relativ zueinander verschieben, was durch eine Bereitstellung der sich Luminaire covers cut to a miter, so that in these areas a shift in the position of the lamp covers each other would have a particularly adverse effect. In such a configuration, it is desirable that the impact areas do not shift due to the thermal expansion relative to each other, resulting in provision of the

Unter„gegenüberliegend" ist in diesem Zusammenhang zu verstehen, dass die Reibungsbereiche unmittelbar benachbart zu den Stoßbereichen bzw. über die Stoßbereiche hinweg angeordnet sind, so dass die Reibungsbereiche in Draufsicht gesehen schräg gegenüberliegend zueinander angeordnet sind. Mit anderen Worten kann in den Stoßbereichen entweder an jedem stirnseitigen Ende der zueinander positionierten Leuchtenabdeckungen je ein Reibungsbereich vorgesehen werden oder es können gemeinsame (über die Abwinklung verlaufende) Reibungsbereiche der zueinander positionierten Leuchtabdeckungen vorgesehen werden. Auf diese Weise besteht die Möglichkeit, dass die aneinander stoßenden Leuchtenabdeckungen sicher zusammengehalten werden und eine Ausdehnung nur in den gegenüberliegenden Stirnbereich der entsprechenden Leuchtenabdeckungen erfolgen kann. opposite friction areas in the joint areas can be prevented. In this context, by "opposite" is meant that the friction regions are arranged immediately adjacent to the joint regions or over the joint regions, so that the friction regions are arranged obliquely opposite one another in plan view a frictional area can be provided for each front end of the luminaire covers positioned relative to each other or it is possible to provide common frictional areas of the luminous covers positioned relative to one another the opposite end region of the corresponding lamp covers can be done.

Figur l zeigt eine schematische Draufsicht einer ersten erfindungsgemäßen FIG. 1 shows a schematic plan view of a first invention
Lichtbandleuchte 10. Die Lichtbandleuchte 10 umfasst dabei eine im Querschnitt im Wesentlichen u-förmige Lichtbandschiene 11, in der insbesondere ein Geräteträger (nicht gezeigt) zur Aufnahme der notwendigen Elektronik und ein Leuchtmittelträger (nicht gezeigt) zur Aufnahme der eigentlichen Leuchtmittel (beispielsweise Continuous line luminaire 10. The continuous luminaire 10 comprises a cross section in the Substantially U-shaped light rail 11, in particular a device carrier (not shown) for receiving the necessary electronics and a light source carrier (not shown) for receiving the actual lighting means (for example
Leuchtdioden, Leuchtstoffröhren, etc.) angeordnet sind. Light-emitting diodes, fluorescent tubes, etc.) are arranged.
Die Lichtbandschiene 11 ist dabei durch eine zwischen den Schenkeln der The light rail 11 is characterized by a between the legs of
Lichtbandschiene 11 angeordnete Leuchtenabdeckung 12 abgedeckt, von der in Figur 1 nur die Lichtabstrahlfläche und nicht deren längsseitigen Rast- oder Klemmmittel erkennbar ist. Die Rast- oder Klemmmittel erstrecken sich bevorzugt im Wesentlichen über die gesamte Länge der Leuchtenabdeckung 12, also im Wesentlichen über die gesamte Längsachse der länglichen Lichtbandleuchte 10. Roof light rail 11 arranged light cover 12 covered, of which in Figure 1, only the light emitting surface and not the longitudinal side locking or clamping means is recognizable. The latching or clamping means preferably extend substantially over the entire length of the lamp cover 12, that is to say substantially over the entire longitudinal axis of the elongate continuous strip lamp 10.

In diesen Reibungsbereichen 13, 14 ist jeweils ein Noppenband angeordnet. Diese Between the light band rail 11 and the lamp cover 12, in the preferred embodiment, two opposite friction regions 13, 14 (indicated by the highlighted gray areas) are provided. In these friction regions 13, 14 a nubbed strip is arranged in each case. These
Noppenbänder weisen auf beiden gegenüberliegenden Seiten Noppenstrukturen auf, um die Reibung zwischen der Leuchtenabdeckung 12 und der Lichtbandschiene 11 derart zu erhöhen, dass in diesen Reibungsbereichen 13, 14 im Wesentlichen keine Relativbewegung mehr zwischen der Leuchtenabdeckung 12 und der Knob bands have knob structures on both opposite sides in order to increase the friction between the lamp cover 12 and the light band rail 11 in such a way that in these friction areas 13, 14 substantially no relative movement between the lamp cover 12 and the
Lichtbandschiene 11 mehr erfolgt, so dass eine Ausdehnung in Längsrichtung der Leuchtenabdeckung 12 im Wesentlichen symmetrisch von diesen Reibungsbereichen 13, 14 erfolgt. Dadurch werden die stirnseitigen Abstände der Leuchtenabdeckung 12 von der Lichtbandschiene 11 ebenfalls symmetrisch verändert, so dass ein optisch harmonischer Gesamteindruck der Lichtbandleuchte 10 bzw. eines Leuchtensystems erhalten bleibt, auch wenn sich die Lichtbandschiene 11 und/oder die Light band rail 11 is more, so that an extension in the longitudinal direction of the lamp cover 12 substantially symmetrically from these friction regions 13, 14 takes place. As a result, the frontal distances of the lamp cover 12 are also changed symmetrically by the light rail 11, so that a visually harmonious overall impression of the strip light 10 or a lighting system is maintained, even if the light rail 11 and / or the
Leuchtenabdeckung 12 aufgrund der betriebsbedingten thermischen Ausdehnungen relativ zueinander bewegen. Wie oben bereits ausgeführt, können zusätzlich oder alternativ auch doppelseitige Klebebänder, einseitige Klebebänder mit Anti-Rutsch- Beschichtung oder andere geeignete Reibungsfolien eingesetzt werden. Auch ist es möglich, die (Kontakt-)Oberflächen der Leuchtenabdeckung 12 und der Lichtbandschiene 11 zu bearbeiten (insbesondere aufzurauen), um einen geeignet hohen Reibungswert bereitstellen zu können. Luminaire cover 12 move relative to each other due to the operational thermal expansions. As already stated above, in addition or as an alternative, double-sided adhesive tapes, one-sided adhesive tapes with an anti-slip coating or other suitable friction films can also be used. It is also possible, the (contact) surfaces of the lamp cover 12 and the Lichtbandschiene 11 to edit (in particular roughen) in order to provide a suitable high friction value can.
