Abstract
Description
FIELD OF THE INVENTION
[0001] The invention relates to an angular deflection element for a strip light (in particular an LED strip light), and also to a related lighting device having such an angular deflection element. BACKGROUND OF THE INVENTION
[0002] Strip lights (such as LED strip lights) are used for illuminating the interior of furniture, and the strip lights are equipped with lighting elements only on one of their two sides. For example, the strip light is adhered to the inner side of the furniture wall, but the strip light can only be installed at the inner corner in an uncertain and thus non-reproducible manner. This may cause the strip light to block light, or cause the side of the strip light with the lighting elements installed not to face inward as desired. In this case, the inner corner will not be illuminated or the illumination will be asymmetric. So far, the solution to this problem is to install two strip lights electrically connected to each other through separate coupling elements at the inner corner. For this purpose, the coupling elements must be positioned and fixed at the inner corner. SUMMARY OF THE INVENTION
[0003] In contrast, the task of the present invention is to install a strip light at the inner corner as simply as possible and with a very small assembly workload without interrupting the lighting image and without the need for a separate coupling element.
[0004] According to the present invention, the task is solved by an angular deflection element for a strip light, in particular an LED strip light, which has:
[0005] - a lower side forming a flat bottom surface, and
[0006] - an upper side guide rail for the strip light, in particular a bar-shaped guide rail, which has: two rail legs, these rail legs forming an angle of about 45° to about 135°, in particular about 90°, with respect to the flat bottom surface; and an angular deflection rail section located between the two rail legs, the angular deflection rail section protruding from the two rail legs, wherein the inwardly inclined lateral inclination of the angular deflection rail section with respect to the flat bottom surface is greater than the inwardly inclined lateral inclination of the two rail legs.
[0007] According to the present invention, the guide rail can ensure that the strip light placed thereon always has the side with the lighting elements installed facing outward, thereby preventing the inner corner from being unlit or having shadows. The strip light is fixed to the angular deflection element and remains in contact with the guide rail. The installation workload of the strip light with the changed direction is greatly reduced and simplified.
[0008] Particularly advantageously, when viewed in the longitudinal direction from the free end of the track towards the angular deflection rail section, the outer edges of the two rail legs rise due to the increased lateral inclination with respect to the flat bottom surface. The inner edges of the two rail legs can (but do not have to) remain at the original height of the free track end unchanged and gradually move outward to ensure that the width of the guide rail remains constant along the entire guide rail.
[0009] The transverse inclination of the free rail ends of the two rail legs is preferably between 0° and approximately 5°, in particular 0°, and the transverse inclination of the angular deflection rail section is preferably between approximately 80° and 90°, in particular 90°.
[0010] For example, the angular deflecting track section can have rounded inner corners, in particular partially cylindrically curved inner corners, as a support surface for the light strip.
[0011] It is particularly preferred that, viewed in the longitudinal direction of the track from the free track ends of the two track legs to the angular deflection track section, the inwardly inclined lateral inclination of the two track legs increases continuously and, in particular, transitions steplessly to the outwardly inclined lateral inclination of the angular deflection track section to form a continuous light strip support surface.
[0012] It is particularly preferred that the angular deflection element has at least two first hooks, which respectively engage laterally on two rail legs, and / or at least one second hook, which engages laterally on the angular deflection track on the side of the angular deflection track facing away from the flat bottom surface. The light strip is hooked onto the angular deflection element by the first and / or second hooks and is kept in contact with the guide rail. The installation work of the light strip with the changed direction is greatly reduced and simplified.
[0013] It is particularly advantageous if, viewed in the longitudinal direction of the track from the free track end to the angular deflection track section, the outer edges of the two rail legs rise at least to the height of the second hook due to the increasing transverse inclination. The inner edges of the two rail legs can (but do not necessarily) remain unchanged at the original height of the free track end and gradually move outwards to ensure that the width of the guide rail remains constant along the entire track.
[0014] The first hook can engage laterally on the two rail legs from the inside and / or outside of the two rail legs, specifically preferably at the free rail ends of the two rail legs.
[0015] In order to save material and simplify the production process, the rail leg and / or the angular deflecting rail section can have at least one groove.
[0016] It is particularly preferred that at least the angular deflection track section, in particular the entire angular deflection element, is mirror-symmetrical to a plane which extends at right angles to the flat bottom surface and in which the angle bisector of the angle lies. This measure results in a correspondingly mirror-symmetrical illumination image.
[0017] It is particularly advantageous if the angle deflecting element can be a one-piece injection-molded part made of plastic, in particular transparent plastic.
[0018] Preferably, the flat bottom surface and / or the guide rail are designed as self-adhesive adhesive surfaces, for example, a double-sided adhesive film is adhered to the flat bottom surface or the guide rail.
[0019] The present invention also relates to a lighting device, which comprises: an inner angle with an inclination angle between about 45° and about 135°, especially about 90°; a light strip laid along the inner angle, especially an LED light strip; and an angle deflection element formed as described above, which is fixed (especially adhesively) on the inner angle, wherein the light strip is fixed on the angle deflection element and abuts against a guide rail. The upper side of the LED light strip with LEDs faces inwards at the inner angle, so as to obtain a continuous light strip that does not break even at the inner angle.
[0020] Preferably, the light strip is hooked to the angle deflection element and / or adhered to the guide rail by a first and / or second hook.
[0021] In an advantageous embodiment, the inner angle is formed by an angled profile groove with a groove bottom, and the angle deflection element is fixed on the groove bottom, especially adhesively fixed on the groove bottom. Description of the Drawings
[0022] Other advantages of the present invention can be derived from the description, claims and drawings. The above-mentioned features and the features to be further listed can also be used alone or in any combination. The embodiments shown and described should not be understood as exhaustive, but are exemplary for the description of the present invention.
[0023] In the drawings:

[0025] Figure 2a , 2b shows a perspective view ( Figure 2a ) and a top view ( Figure 2b ) of the angle deflection element according to the present invention, which has an LED light strip guided thereon; and
[0026] Figures 3a - 3c A lighting device with an LED light strip is shown, and the LED light strip is laid at the inner angle through the angle deflection element of the present invention. Detailed Embodiments
[0027] Figures 1a - 1c The shown angle deflection element is used for performing a determined angle deflection on the LED light strip at the inner angle of the lighting device. The angle deflection element is preferably an injection molded part made of transparent plastic.
[0028] The corner guide element 1 is here only exemplarily designed as a corner body, which has a lower side forming a flat bottom surface 2 and, on the upper side, a guide rail 3 for a light strip, which is here only exemplarily designed as a strip. The guide rail 3 includes two rail legs 4, the angle α between which with respect to the flat bottom surface 2 is between approximately 45° and approximately 135°, in this example 90°, and includes an inner corner rail section 5 located between the two rail legs 4, which inner corner rail section projects beyond the two rail legs 4. As shown in the figure, the corner deflection rail section 5 is formed with an inner rounding, i.e., it is bent inwards around a curvature axis 6, which extends at a right angle (or obliquely) to the flat bottom surface 2. The corner deflection rail section 5 is preferably rounded in a partially cylindrical shape. Optionally, the guide rail 3 can be defined by the side edges of the corner guide element 1 or by a groove in the corner guide element 1.
[0029] The free track ends 7 of the two rail legs 4 have a lateral inclination of 0° with respect to the flat bottom surface 2, while the outer inclination lateral inclination of the corner deflection rail section 5 is approximately 90°. When viewed in the track longitudinal direction from the free track ends 7 of the two rail legs 4 to the corner deflection rail section 5, the lateral inclination of the two rail legs 4, which are inclined outwards, continuously increases and in particular transitions smoothly to the lateral inclination of the corner deflection rail section 5. In other words, in FIG. 1, the guide rail 3 turns from the horizontal direction of one free track end 7 to the vertical direction in the corner deflection rail section 5 and then turns back to the horizontal direction from the other free track end 7.
[0030] The corner deflection element 1 respectively has two first hooks 8, which respectively engage on the free track ends 7 from the outer sides of the two rail legs 4 laterally (i.e., along the transverse direction), specifically at a distance d that is slightly greater than the strip thickness D of the LED strip to be guided ( Figure 2a ). The corner deflection element 1 also has a second hook 9 on the side of the corner deflection rail section 5 facing away from the flat bottom surface 2, which second hook is arranged in the middle here and engages laterally on the corner deflection rail section 5, specifically at a distance d that is slightly greater than the strip thickness D of the LED strip to be guided ( Figure 2a ). The second hook 9 preferably extends along the rounded corner deflection rail section 5 and is rounded accordingly with the rounded corner deflection rail section 5.
[0031] As Figure 1a shown, when viewed in the track longitudinal direction from the free track ends 7 to the corner deflection rail section 5, the outer edges 10 of the two rail legs 4 rise to the height of the second hook 9 due to the increasing lateral inclination. In contrast, the inner edges 11 of the two rail legs 4 remain at the original height of the free track ends 7 unchanged, but move outwards more and more to ensure that the width b of the guide rail 3 remains constant along the entire guide rail 3.
[0032] As Figure 1a shown by the dashed line in the figure, the corner deflection rail section 5 can have a central groove 12 to save material and simplify the manufacturing process. Alternatively or additionally, the two rail legs 4 can also have such a groove.
[0033] The angular deflection rail section 5, in particular the entire angular deflection element 1, is preferably mirror-symmetrical with respect to a plane 13 which is at right angles to the flat base 2 and on which the angular bisector of the angle α lies.
[0034] As Figure 1c shown, a double-sided adhesive film 14 can be pasted on the flat base 2, so that the flat base 2 has self-adhesion.
[0035] In the illustrated embodiment, the angular deflection element 1 is an angular body with two angular legs, the lower side of which forms the flat base 2 and the upper side of which forms the guide rail 3.
[0036] In Figure 2a 、 2b , an LED strip 15 is equipped with LED lights (not shown) on its upper side, the LED strip is placed on the guide rail 3 and kept in contact with the guide rail 3 by the first and second hooks 8, 9. The profile of the guide rail 3 corresponds to the profile of the LED strip 15. When the two rail legs 4 of the LED strip 15 (the upper side of each rail leg 4 equipped with an LED faces upwards) are oriented at an angle α, the LED strip 15 automatically twists due to its inherent stiffness. The LED strip 15 is hooked to the angular deflection element 1 by the first and second hooks 8, 9 and rests on the guide rail 3 with its lower side without the LED lights.
[0037] As an alternative or in addition to being hooked, the LED strip 15 can also be glued to the guide rail 3.
[0038] Figures 3a - 3c shows an illumination device 20, the angle α of the inner angle 21 of which is between approximately 45° and 135°, in this example 90°, the illumination device having an LED strip 15 laid along the inner angle 21 and an angular deflection element 1. The angular deflection element 1 together with the LED strip 15 hooked therein is fixed to the inner angle 21, for example, by means of a double-sided adhesive film 14 or the like.
[0039] The inner corner 21 can for example be formed by an angled profile groove 22 of a profile frame 23 (made of a metal such as aluminium), as shown in the embodiment. For example, the width b of the LED strip 15 is 8 millimetres and the inner profile cross-section of the profile groove 22 is at least 10 millimetres x 10 millimetres. The LED strip 15, inserted into the profile groove 22 with the LED-equipped upper side facing upwards, rests on the groove bottom 24 of the profile groove 22 and is, for example, adhered to the groove bottom 24 by means of a double-sided adhesive film 14. At the inner corner 21, the LED strip 15 is deflected in a defined manner by the corner deflection element 1 adhered to the groove bottom 24. The LED-equipped upper side of the LED strip 15 faces upwards in the profile groove 22 and inwards in the inner corner 21, so that overall a continuous strip of light is obtained which is not interrupted even at the inner corner 21. Thus, the situation where the inner corner is not illuminated is avoided in the lighting device 20. The profile groove 22 can be closed with a light-transmissive cover (not shown here).
