Description

[Technical field]

[0001] The present invention relates generally to a lighting device, and more particularly to a lighting device comprising a lens body. [Background technology]

[0002] The market for light emitting diodes (LEDs) continues to expand. LEDs have many advantages over traditional light sources such as incandescent, fluorescent, and sodium lamps. To name a few, they are more energy efficient, have longer life spans and higher efficacy, and offer design flexibility.

[0003] One trend is to combine the advantageous properties of LEDs according to the above with the use of flexible strips so that light can be provided to recessed or narrow areas, such as shelves and kitchen cupboards. Flexible LED strips can be cut or stretched to a desired length, thus meeting several lighting needs. Because they are flexible, they can be bent and molded into different shapes. Moreover, they are compact, resulting in easy installation and use.

[0004] The intensity profile of standard flexible LED strips is often Lambertian or close to Lambertian. This characteristic can be undesirable, for example, when used with linear shelves or counters, because these areas of use often require linear spotlights where the light is mostly collimated and directed towards the surface, instead of a Lambertian intensity distribution. In addition to this, the use of standard flexible LED strips can also result in glare from the light sources, and the possibility of individual light sources becoming visible. These results can be perceived as unpleasant by people near the light sources.

[0005] There is therefore interest in providing a continuous, compact, linear light source, preferably using LEDs, to illuminate a surface with targeted light output while avoiding glare. Summary of the Invention [Problem to be solved by the invention]

[0006] The present invention aims to provide a lighting device that is able to provide a targeted light output while simultaneously preventing glare from the arrangement.

[0007] This and other objects are achieved by a lighting device having the features of the independent claims. Preferred embodiments are defined in the dependent claims. [Means for solving the problem]

[0008] Therefore, according to the present invention, there is provided a lighting device comprising an elongated lens body extending in a length direction L, the lens body being defined by a first end face E1 and a second end face E2 extending laterally and facing each other, and a first side face S1, a second side face S2 and a third side face S3. Each side face connects the first end face with the second end face. The lens body includes at least one recess extending along the length direction and only on at least one of the first side face and the second side face, the first side face being oriented at an angle α with respect to the second side face, 60°<=α<=120°. The lighting device further comprises at least one array of a plurality of light emitting diodes, LEDs, arranged inside at least one of the at least one recess. According to the invention, a first side extension is provided, extending beyond the edge C between the first side and the second side, the extension being configured to be bent towards and attached to at least one of the lens body and the second side. Thus, the first side extension may be bent towards and attached to the lens body and / or the second side. This embodiment is particularly advantageous in that when the extension is bent towards (and optionally attached to) the second side, it adds rigidity to the lighting device, making it more robust. Furthermore, the first side extension may for example hide any cuts made in the lens body and / or the second side, making it more aesthetically appealing. The extension may partially or completely cover the second side and may for example be reflective, thus determining the (partial) reflectivity of the second side.

[0009] The invention is therefore based on the idea of ​​a compact linear lighting device or system capable of providing a targeted light output, primarily suitable for illuminating elongated surfaces by emitting an asymmetric beam in a direction transverse to the longitudinal direction L, while preventing glare.

[0010] It will be appreciated that the beam of light emitted from an array of LEDs may be asymmetric, which results in minimization of glare as the beam does not radiate in a single direction, thus providing more even illumination of a space or area, such as the space in which the lighting device resides.

[0011] The present invention is further advantageous in that the lens body in combination with the arrangement of an array of multiple LEDs within at least one recess allows for the provision of a targeted light output, which facilitates providing illumination of more distinct portions of a space or area.

[0012] According to the lighting device of the present invention, at least one array of a plurality of light emitting diodes, LEDs, is provided. By the term "array" it is meant here a (linear) configuration, or the like. Thus, by the term "at least one array of a plurality of LEDs" it is meant here that the array of LEDs constitutes a linear configuration or chain of LEDs, or the like.

[0013] By "lens body", it is meant here a (elongated) element of translucent material, structure, or the like, configured to affect light in such a way that at least some light can pass through the lens body. By the term "recess", it is meant here a hollow enclosure recessed or indented into the surface of an object. Thus, by "the lens body includes at least one recess", it is meant here that the lens body includes one or more hollow enclosures. Such elongated lens bodies can typically be manufactured through extrusion molding.

[0014] According to one embodiment of the present invention, a lighting device is provided, in which at least the array of LEDs constitutes a continuous linear light source. Thus, the light emitted from the array of LEDs may constitute a continuous light source. This embodiment is advantageous in that the array of LEDs may constitute a continuous linear light source, thereby further reducing the risk of glare. The risk of individual "light pixels" being visible is also further reduced, thus resulting in a more pleasant light experience for people in the space in which the lighting device is present.

[0015] According to an embodiment of the present invention, a lighting device is provided in which at least one of the first side S1 and the second side S2 may be at least partially reflective. Thus, the first side of the first side and / or the first side of the second side may be partially or fully reflective, both of which face the lens body. This embodiment is advantageous in that the beam of the array of LEDs may be reflected to some extent, thus improving the intensity distribution of the light of the array of LEDs. This allows a smaller space to be illuminated with less diffusion of the light of the array of LEDs, thus resulting in a higher illuminance. Furthermore, potential glare of the light of the array of LEDs is further reduced, presenting a more pleasant light for the user. It will be appreciated that the beam of the light of the array of LEDs can be shaped as a result of the first side of the first side and / or the first side of the second side being at least partially reflective. This embodiment is advantageous in that it may facilitate different lighting needs, for example the provision of light to specific areas within the space in which the lighting device is present.

[0016] According to an embodiment of the present invention, the lighting device may comprise at least one fastening element disposed on at least one of the second side of the first side and the second side of the second side. In other words, the lighting device may comprise a fastening element disposed on the second side of the first side and / or on the second side of the second side, both of which face away from the lens body. This embodiment is particularly advantageous in that the installation of the lighting device is more easily performed. In addition, the arrangement of the fastening element in this embodiment provides a more versatile approach to mounting the lighting device.

[0017] According to an embodiment of the present invention, the lighting device may comprise at least one element constituting a linear structure which may extend in a length direction L. The at least one element may be disposed inside at least one of the at least one recesses, and the at least one element may partially surround the at least one array of LEDs. In a cross section P of the lighting device along the length direction L, the at least one element may extend in the cross section P up to the lens body, whereby the at least one element may provide a spacing A in the cross section P between the lens body and the at least one array of LEDs. In other words, the element constituting the linear structure extending in the length direction L may be disposed in the recess and provide a spacing A between the lens body and the array of LEDs. The element may partially surround the array of LEDs and extend in the cross section P towards the lens body. This embodiment is advantageous in that the linear structure of the element ensures the spacing A between the lens body and the array of LEDs, thus avoiding physical contact between them in the recess. Because optical contact between the lens and the array could adversely affect the shape of the beam and could also affect the spectrum in an undesirable manner, this embodiment is advantageous in that one or more of these negative effects can be mitigated or avoided, resulting in even further improved light output.

[0018] According to an embodiment of the present invention, at least one of the at least one elements may have at least partial reflectivity. Therefore, one or more of the elements may have partial or total reflectivity. This embodiment is advantageous in that the elements can reflect the light beam of the array of LEDs, thus improving the light intensity distribution even more. This may therefore result in a larger space being illuminated with an even wider spread of light. Furthermore, again, the potential glare of the light of the array of LEDs is reduced, presenting a more pleasant light for the user. It is noted that the light beam of the array of LEDs can be adjusted as a result of the elements having at least partial reflectivity. This is beneficial because this embodiment may cater to different lighting needs, for example, the delivery of light to a specific area within a larger space in which the lighting device is present.

[0019] According to an embodiment of the present invention, the lighting device may comprise at least one of a first set of at least two adjacent arrays of a plurality of LEDs and a second set of at least two adjacent arrays of a plurality of LEDs, the first set of at least two adjacent arrays of a plurality of LEDs may be arranged in at least one recess arranged along a first side (in the lens body) and the second set of at least two adjacent arrays of a plurality of LEDs may be arranged in at least one recess arranged along a second side (in the lens body). Thus, the first set of two or more adjacent arrays of a plurality of LEDs may be arranged in a recess along a first side and the second set of two or more adjacent arrays of a plurality of LEDs may be arranged in a recess along a second side. This embodiment is particularly advantageous in that the lighting device can illuminate a larger space or highlight different sections in the illuminated space in which the lighting device is installed, improving the overall intensity distribution. Following this, the risk of glare can be even further reduced. In addition, it entails that the lighting device becomes versatile with regard to different lighting needs and / or desires, for example with regard to providing light to a particular area.

[0020] According to an embodiment of the present invention, the lighting device may comprise a control unit configured to independently control at least one of the at least one array of LEDs. The control unit may therefore control the arrays of LEDs independently of each other. This embodiment is advantageous in that the light of the arrays of LEDs can be controlled via the control unit according to different lighting needs and / or desires, for example with regard to providing light to a particular area.

[0021] According to one embodiment of the present invention, the lighting device may include a single recess disposed along a first side and a single array of LEDs, the single array of LEDs may be disposed within the single recess (within the lens body), and the second side may be at least partially reflective.

[0022] According to an embodiment of the present invention, at least two arrays of a plurality of LEDs are provided, where at least one first array of the plurality of LEDs may be configured to emit a first light and at least one second array of the plurality of LEDs may be configured to emit a second light, and the first light and the second light may be different. In other words, the two arrays of the plurality of LEDs may emit different lights. By the expression "the first light and the second light may be different", it is meant here that at least one characteristic of the first light is different (i.e. not the same) as the characteristic(s) of the second light, such as different wavelength, color, intensity, etc. This embodiment is advantageous in that it is more adaptable with respect to different lighting needs, requirements, and / or desired environments, as well as aesthetically appealing. In addition, this embodiment is further advantageous in that the plurality of arrays may be arranged such that the respective light of the plurality of LEDs may interfere with each other. This embodiment entails that the lighting device becomes versatile with respect to different lighting needs and / or desires, for example with respect to providing light to a specific area.

[0023] According to an embodiment of the present invention, the lighting device may be flexible. This embodiment is particularly advantageous in that the lighting device may be rolled up, for example, on a roll, making it easier to transport and handle. In addition to this, this embodiment facilitates the mounting of the lighting device. Furthermore, the flexibility increases the possible space in which the lighting device may be mounted, making the invention more adaptable to different lighting needs and / or desired environments.

[0024] According to an embodiment of the present invention, it is provided that within a cross section P of the lighting device along the length direction L, the lens body may be further defined by the side S3 being curved around the length direction L according to a circular arc D. The circular arc D has a first end point Z1 at / on the first side and a second end point Z2 at / on the second side. The circular arc D therefore defines the shape of the lens body between the first and second end points Z1, Z2, which may be convex. This embodiment is advantageous in that it produces an asymmetric beam of light of the array of multiple LEDs, thereby illuminating a desired space while minimizing undesired glare to people occupying the space in which the lighting device is present.

[0025] According to one embodiment of the present invention, the second side may be perpendicular to the first side, whereby the first side and the second side may define and extend the lens body to have a quadrant cylinder shape. This embodiment is particularly advantageous in that it optimizes light distribution. Thus, this embodiment may further minimize glare from the light of the array of multiple LEDs.

[0026] According to an embodiment of the invention, the lighting device may comprise at least one incision provided perpendicular to the length direction L. The at least one incision, i.e. the incisions, are arranged essentially parallel to one another along the length direction L inside at least one of the lens body and the second side. Optionally, the extension may also comprise a (partial) incision extending parallel to and arranged in the incision in the lens body. By "incision" it is meant here a cutting, a groove or the like. This embodiment is advantageous in that the incision may increase the flexibility of the lighting device. This facilitates the transportation and handling of the lighting device, since the lighting device may be rolled up, for example, on a roll. In addition to this, this embodiment may facilitate the mounting of the lighting device on a substrate that is relatively sharply curved. Furthermore, this embodiment results in the lighting device being more adaptable to different lighting needs and / or desired environments.

[0037] The lighting device 100 further comprises at least one fastening element 150 arranged on a first outer side W1 of the first side S1, i.e. on the outer surface of the lens body, and / or on a second outer side W2 of the second side S2, i.e. on the outer surface of the lens body.

The element 160 extends in a cross section P of the lighting device 100 along a length direction L. The spacing A makes it possible to avoid physical contact between the lens body 110 and the at least one array 130 of the plurality of LEDs 140 when the lighting device 100 is being transported, for example, in a rolled-up manner, or during installation. In addition, the spacing A further makes it possible to avoid optical contact between the lens body 110 and the at least one array 130 of the plurality of LEDs 140 when the lighting device 100 is installed, for example, in a bent manner. The at least one element 160 may include a linear structure 170 extending in a length direction L, which may extend over the entire at least one recess 120 in which it is disposed, or only over a portion of the at least one recess 120.

It should be noted that the lighting device 100 shown in Fig. 4 has many features in common with the lighting device 100 shown in Fig. 2 and / or Fig. 3, and therefore it is to be noted that reference should be made to Fig. 2 and / or Fig. 3 and the respective associated text for an improved understanding of the features and / or functions of the lighting device 100. The lighting device 100 comprises a first set 180 of two or more adjacent arrays 130 of a plurality of LEDs 140 and / or a second set 190 of two or more adjacent arrays 130 of a plurality of LEDs 140, the first set 180 of two or more adjacent arrays 130 of a plurality of LEDs 140 may be disposed in a recess 120 disposed along a first side S1, and the second set 190 of two or more adjacent arrays 130 of a plurality of LEDs 140 may be disposed in a further recess 121 disposed along a second side S2. The first set 180 may be configured to emit a first light and the second set 190 may be configured to emit a second light, where the first light and the second light are different.

It should be noted that the lighting device 100 shown in FIG. 5 has many features in common with the lighting device 100 shown in FIG. 2-FIG. 4, and therefore it is to be noted that reference should be made to this (these) figures, and the respective associated text, for an improved understanding of the features and / or functions of the lighting device 100. The lighting device 100 comprises a first side S1 and a second side S2, the second side S2 being perpendicular to the first side S1, whereby the first side S1 and the second side S2 define the lens body 110 to have the shape of a quarter cylinder and extend thereto. Thus, the angle α may be 90°. The shape of the lens body 110 may have a different shape, dimension, and / or size than that shown, such as a quarter of an elliptical cylinder, or slightly smaller / larger than a cylinder or an elliptical cylindrical lens.

[0044] The array 130 of LEDs is embodied as a flexible LED strip, and the lens body 110 is made of a light-transmitting flexible material. The lighting device 100 further comprises a plurality of notches 210 (partially indicated in ghost) provided inside the lens body 110 and at least one of the second side S2 along the length direction L. Each notch 210 extends perpendicular to the length direction L and from the second side S2 to the third side S3. The notches 210 may allow linear bending and thus improve the flexibility of the lighting device 100, thus allowing it to be rolled up, for example, on a roll. The lighting device 100 may have some flexibility without the at least one notch 210, but the at least one notch 210 may improve the flexibility.

[0047] Those skilled in the art will understand that the present invention is in no way limited to the above-described preferred embodiment. Rather, many modifications and variations are possible within the scope of the appended claims. For example, one or more of the at least one recess 120, the at least one element 160, the arc D of the lens body 110, etc. may have shapes, dimensions, and / or sizes different from those shown / described.
