    Technical area
    The invention relates to a linear lamp according to the preamble of independent claim 1. Such linear lamps with a light source, a primary optics, which covers the light source in its Abstrahlbereich, and a linear lamp final secondary optics can for the illumination of indoor and outdoor spaces or for the illumination of desks, displays, etc. are used.
    State of the art
    For the illumination of indoor and outdoor spaces nowadays longitudinal lamps are often used, which extend along a space or an object to which they are arranged. Such lights are commonly referred to as linear lights and can, for example, directly on walls, suspended or mounted on ceilings or attached to it.
    Typically, linear lights include a straight or curved usually elongated or longitudinal base profile, which is attached directly or indirectly to the object or the wall or the ceiling. In addition, linear lights usually have a light bar along which a longitudinal light source or a series of light sources such as LED LeuchtmitteIn and associated control gear are attached.
    When using a series of light-emitting diodes as light sources (LED bulbs) is typically generated without additional optics or lens, a punk-shaped line on an illuminated surface. The shape of the dots is dependent on the shape of the LEDs and they may be circular, square, rectangular or similar. Such punctiform illumination is undesirable in many applications of linear lights.
    In order to avoid punctiform illumination or to improve the illumination, primary lenses or primary optics are regularly used, which cover the light emitting diodes so that the emitted light has preferred emission characteristics. For example, primary optics determine the hue, scatter and / or direction of the emitted light. With respect to the illuminated surface, primary optics can be used to adjust the emitted light so that, instead of the dot-shaped line, more or less a solid line of a certain width is created on the illuminated surface. Although this may bring about an improvement in the lighting situation, such a line is often not preferred.
    In order to achieve a wider illuminated longitudinal surface with LED bulbs, linear lights can at least in a section transparent cover or an outdoor diffuser include as secondary optics covering at least the LED bulbs or the primary optics in the emission area or encloses. In this case, the primary optics can be configured to bundle or distribute the light emitted by the light-emitting diodes as completely as possible to the secondary optics or its transparent section. In order to form the light emitted by the linear lamp, the secondary optics may have a wave or jagged outside, whereby the radiated light can cover a wider illuminated longitudinal area and the light distribution curve (LVK) of the lamp can be adjusted. The disadvantage here is that the emitted light generated due to the wave or jagged outside lines on the illuminated surface, which is often not desirable.
    To this effect. To curb it is known to cover the inside of the secondary optics with a light scattering film. Thus, a comparatively flat longitudinal illumination can be achieved substantially without banding. A disadvantage of such embodiments is that the light scattering film reduces the light intensity, resulting in a loss of efficiency of the linear lamp by itself. Furthermore, such light scattering films form an additional element in the linear lamp, which can make their production more expensive and expensive. In addition, such light scattering films reduce the possibilities in the design of the linear lamp, which is why they are often undesirable for design reasons.
    Against this background, it is an object of the following invention to propose a linear lamp, which allows in particular with an LED illuminant or a series of LEDs an efficient, longitudinal area, adapted lighting.
    Presentation of the invention
    The object is achieved according to the invention by a linear lamp, as defined by the features of the independent claim 1. Advantageous embodiments of the invention will become apparent from the dependent claims.
    The essence of the invention consists in the following: A linear lamp with a light source, a primary optics, which covers the light source in its Abstrahlbereich, and a linear light terminating secondary optics, comprises a arranged between the primary optics and the secondary optics Intermediäroptik which a radiation of the Covering the primary optics, the secondary optics covering a radiation area of the intermediate optics.
    The term "radiation area" refers in the context of the invention to a portion of the light source or the primary optics or the Intermediäroptik which emits light in an installed state of the linear light. In particular, the emitting region of the luminous means refers to the portion of the luminous means which emits light when the liner luminaire is mounted and switched as intended. Analogously, the emission ranges of the primary optics and the intermediate optics in each case relate to an area from which light emanates or is emitted when the linear luminaire is mounted and switched on as intended.
    The primary, secondary and intermediate optics may comprise a transparent portion such as the body portions of the secondary and intermediate optics described below, which may be provided in particular for covering an adjacent radiation area. In addition to this transparent section, the primary, secondary and intermediate optics may also include other elements. For example, such elements may be an attachment for mounting to the linear light or a base profile thereof and / or a lateral cover or side walls.
    The primary optics can be provided, for example, to glare the light generated by the light source. It can also concentrate or distribute the light generated by the luminous means, for example in the direction of the secondary optics. In this way, it is possible to dispense with further elements for bundling the light, for example reflectors, or their construction can be simplified.
    The secondary optics can in particular complete the linear lamp towards the outside and thus be in a built-in or assembled state of the linear light of the essential visible part of the linear lamp. Preferably, the secondary and intermediate optics are made in one piece.
    The primary, secondary and Intermediäroptiken can be made in particular of a plastic such as a polycarbonate (PC) or a polymethyl methacrylate (PMMA). On the one hand, such plastics enable a robust design of the optics in many possible geometries. On the other hand, they can be translucent in many ways, so that the desired radiation characteristic or the light distribution curve (LVK) of the linear light can be flexibly predefined and adjusted to an intended application area. In addition, optics made of such a material can be produced relatively simply and inexpensively, for example by injection molding, and have further properties which are preferred for use, for example elasticity or longevity.
    The term "transparent" refers in connection with primary, secondary and intermediate optics to translucent or an at least partially visible light transmittance. The term "translucent" in this context may refer in particular to a damped or undamped permeability of the light generated by means of the luminous means.
    The LVK or emission curve of the linear light can be inter alia in conjunction with a planned emission direction, which refers to a direction of light propagation, in which the linear light illuminates as intended.
    The Intermediäroptik in the novel linear lamp allows the glare by means of the primary optics or directed light scattered or shaped to a certain predefinable extent. As a result, a line formation generated by a corrugated outer side of the secondary optics can be reduced or prevented on a surface illuminated by the linear light. At the same time, this surface may have a suitable width. It can be, for example, a long drawn rectangle.
    Next, the intermediary optics allows the LVK of the linear light can be preferably adjusted and adjusted, with a loss of intensity can be reduced or avoided. For example, a standard LVK may be specified by the primary and secondary optics. The adapted to the actual purpose of the linear lamp out LVK can then be adjusted by a suitable Intermediäroptik. Accordingly, the Intermediäroptik also allows the LVK of the linear light can be flexibly and efficiently defined both by the form of the intermediate optics and their position between the primary optics and secondary optics, and that the linear light is mainly produced with standard components and only the intermediate optics on the concrete Purpose is adapted. Likewise, the use of further light-scattering elements and in particular of light scattering films in the linear luminaire can be avoided. Linear lamps according to the invention can thus be manufactured relatively efficiently and inexpensively and be flexible for adjustments.
    Finally, the inventive design of the linear lamp allows a relatively high flexibility in luminaire design.
    Preferably, the lighting means comprises a series of light-emitting diodes. The lighting means can thus be referred to as LED lighting means. The term "row" may in this context refer to the fact that the LEDs are arranged along a curved, wavy, jagged or in particular straight line.
    The term "light emitting diode" can be understood synonymous with light emitting diode or light emitting diode (LED). The LEDs may be configured, for example, round, elliptical, square or rectangular. They may be arranged on a circuit board, which may additionally be equipped with one or more operating devices and possibly a control electronics for operating the light-emitting diodes.
    LED bulbs have various advantageous properties such as high energy efficiency, long life and cost-effective production. They allow an efficient lighting adapted to the respective application.
    In this case, the primary optics preferably has a number of primary lenses, wherein in each case one primary lens of the row of primary lenses is associated with one of the light-emitting diodes of the lighting means. With such primary lenses, the light emitted by the light-emitting diodes can be effectively deblasted, shaped and / or directed. The primary optics can thus be embodied in one piece or in several parts, for example with a set of individual lenses. In this case, a one-piece design of the primary optics allow a relatively simple installation in the linear lamp and a relatively simple handling.
    Furthermore, the intermediate optics can have a number of light-emitting diode sections, wherein one light-emitting diode section is assigned to one of the light-emitting diodes of the light-emitting device. In this way, the light emitted by the individual light-emitting diodes and penetrating the primary optics can be scattered efficiently.
    Preferably, the intermediate optic comprises a transparent longitudinal body portion which describes a substantially linear longitudinal direction and a cross section lying substantially at right angles to the longitudinal direction. In this case, the body portion has an inner side facing the primary optic and an outer side opposite the inner side and facing the secondary optics.
    The term "longitudinal" in connection with the body portion may refer to a linear shape. In this case, the body portion may be configured substantially straight in a longitudinal section along the longitudinal direction. The inside of the body portion and / or the outside of the body portion may thus be formed in each case in such a longitudinal section or in the longitudinal direction of the body portion as a straight line. In such an embodiment, the body portion in a plan view may describe a rectangular shape.
    Preferably, the inside of the body portion of the intermediate optic in cross section has a convex curvature extending toward the illuminant. The convex curvature of the inside can be circular segment-shaped or elliptical segment-shaped, in particular in cross-section. The term "convex" in connection with the invention may refer in particular to a curvature with respect to the linear lamp or the associated component thereof to the outside.
    Such a curved inside allows a relatively simple and efficient determination of the LVK of the linear lamp. In particular, by this means, for example, the light emitted by the linear light can be efficiently bundled or concentrated in a target area.
    In a preferred embodiment, in this case, the outer side of the body portion of the intermediate optics in cross section has a convex curvature extending away from the illuminant. The convex curvature of the outside can be circular segment-shaped or elliptical segment-shaped, in particular in cross-section. In this way, the LVK of the linear lamp can be efficiently and easily adjusted to its intended use or the radiated light can be shaped.
    In another preferred embodiment, the outer side of the body portion of the intermediate optic in cross section has two analogous convex curvatures. The two uniform convex curvatures of the outside can be connected to each other via a concave curvature. In particular, they can each be circular-segment-shaped or elliptical segment-shaped in cross-section. In this way, the emission characteristic or the LVK of the linear light can be adjusted simply and efficiently so that two parallel areas are illuminated. This can be advantageous, for example, in applications in which laterally more and in the middle less illumination is required. For example, such linear lights can be used in shops with laterally arranged by a gear product displays.
    In another preferred embodiment, the outer side of the body portion of the intermediate optic has a convex curvature in cross section and a plurality of points adjacent thereto. The convex curvature of the outside can be circular segment-shaped or elliptical segment-shaped, in particular in cross-section. The teeth can be different dimensions. For example, they can be dimensioned from the convex curvature of increasingly larger. For example, the outer side of the body portion of the intermediate optic in cross-section, three, four or five points have that become continuously larger, with the subsequent to the convex curvature spikes the smallest and the convex curvature at the farthest point is the largest. In this way, the emission characteristic or the LVK of the linear light can be adjusted simply and efficiently so that one area is bright and one parallel area is illuminated in a damped manner.
    Preferably, the secondary optics comprises a transparent, longitudinal, convex body portion, which describes a substantially linear longitudinal direction and a substantially perpendicular to the longitudinal direction curved cross-section with a circumferential direction. In this case, the body portion of the secondary optics on an inner side and an inner side opposite the outside. Furthermore, it comprises on the outside in the direction of rotation of the curved cross section formed waves.
    The term "circumferential direction" may refer to a tangential direction of the curved cross section and in particular the circular or elliptical segment-shaped curvature of the curved cross section of the body portion or its inner and outer sides.
    The waves on the outside can be used to scatter the light penetrating the body portion of the secondary optics. The term "wave" in connection with the outside and possibly also the inside of the body portion of the secondary optics can refer to any alternately increased and deepened form. It may thus comprise uniform or irregular sawtooth, sinusoidal, angular, stepped or similar shapes.
    In this case, the waves on the outside of the body portion of the secondary optics preferably in the direction of rotation of the curved cross-section on a substantially uniform amplitude. In this way, a virtually uniform surface can be efficiently illuminated and light stiffening or longitudinal brightening can be avoided.
    Preferably, the waves are formed on the outside of the body portion of the secondary optics as concave dents in the outside of the body portion. Alternatively, these waves may also be formed as convex bulges on the outside of the body portion. Such a configuration allows a simple expedient inventive embodiment of the outside of the body portion.
    In particular, the waves on the outside of the body portion of the secondary optics are preferably formed in each case as a convex bulges and a concave indentation on the outside of the body portion. In this way, edges on the outside can be avoided and the radiated light can be gently scattered, so that a surface lighting is generated. These waves preferably describe a sine function or a cosine function. Such waves enable a relatively simple production of the optics and a particularly gentle scattering of the emitted light.
    Preferably, the inside of the body portion of the secondary optics in the circumferential direction of the curved cross section is formed substantially circular segment-shaped or ellipsensegmentförmig. Alternatively, teeth or waves may be formed on the inside of the body portion of the secondary optics. They can be configured in the direction of rotation uniformly or with changing amplitudes.

    Way (s) for carrying out the invention
    Certain terms are used in the following description for convenience and are not intended to be limiting. The words "right", "left", "bottom" and "top" denote directions in the drawing referred to. The terms "inward" and "outward" designate directions toward or away from the geometric center of the linear lamp and designated parts thereof. The terminology includes the words expressly mentioned above, derivatives thereof, and words of similar meaning.
    In Fig. 1 is a perspective view of a first embodiment of an inventive linear lamp 1 is shown with an attachable, for example, on or in a ceiling longitudinal base profile 2. The base profile 2 has a rectangular base plate 21 and two parallel side walls 22 extending from the longitudinal sides of the base plate 21.
    On the base plate 21, a board 4 is mounted with a plurality of screw holes 41. The board 4 is equipped with a series of LEDs 5, which are arranged in a straight line. The light emitting diodes 5 each have a shape which is rectangular in a plan view or a view from below. In operation, they emit light predominantly downwards in a radiation area. The LEDs 5 together form a lamp of the linear lamp. 1
    Adjacent to the light-emitting diodes 5, a primary optic 6 is mounted with a series of primary lenses 61 formed on a base 63. In Fig. 1, the primary optics 6 is displaced in the longitudinal direction a piece to the left, so that the underlying components are visible. The primary lenses 61 are arranged in a straight row, wherein in each case a primary lens 61 is provided for a light-emitting diode 5. Each primary lens 61 covers the radiation area of the associated light-emitting diode 5. In operation, the light emitted by the light-emitting diodes 5 penetrates the primary optics 6 through their primary lenses 61, and the primary optics 6 itself thereby has a radiation area. Between the primary lenses 61 and the base 63, longitudinal grooves 62 are respectively formed on the primary optics 6.
    Adjacent to the primary optic 6, an intermediate optic 3 is mounted with an elongated body portion 31 and two longitudinal side walls 32. In FIG. 1, the intermediate optics 3 is displaced a little to the left in the longitudinal direction so that the components of the linear luminaire 1 lying underneath are visible. The body portion 31 covers the radiation area of the primary optics 6. It has an inner side 312 facing the primary optics and an outer side 311 facing away from the primary optics 6. The side walls 32 merge at their end facing away from the body portion 31 in each case into a nose 33. The lugs 33 engage laterally in the grooves 62 of the primary lenses 61, whereby the Intermediäroptik is attached to the primary optics 6. For assembly or disassembly of the intermediate optics 3, it can be pushed up or down in the longitudinal direction onto the primary lenses 61. In operation, light emanating from the primary optics 6 penetrates the intermediate optics 3 so that it itself has a radiation area.
    On the base profile 2, a longitudinal secondary optics 7 is mounted, which closes the linear lamp 1 to the outside or down. In Fig. 1, the secondary optics 7 is shifted in the longitudinal direction a piece to the left, so that an interior of the linear lamp 1 can be seen. The secondary optics 7 has two side walls 72 connected to the base profile 2 and a convex body portion 71 connecting the two side walls at the bottom. The body portion 71 comprises an inner side 712 facing the intermediate optic 3 and an outer side 711 facing away from the intermediate optic 3. It describes a substantially circular segment-shaped curved cross-section.
    The primary optics 6, the intermediate optics 3 and secondary optics 2 are each made in one piece from a transparent plastic such as a polycarbonate (PC) or a polymethyl methacrylate (PMMA).
    When the linear light 1 is switched on, the light sources 5 surrounding the light emitting diodes 5 of the primary optics 6 of the primary optics 6 bundle or distribute light emitted by the light emitting diodes 5 in such a way that they strike the body section 31 of the intermediate optics 3 essentially completely. The body portion 31 of the Intermediäroptik 3 thus completely encloses the primary optics 6 in their Abstrahlbereich. The intermediate optics 3 directs the light in a predefined manner through the open side of the base profile 2 to the inside 712 of the body portion 71 of the secondary optics 7. The body portion 71 of the secondary optics 7 thus completely encloses the intermediate optics 3 in its emission area. Since, in this way, the light emitted by the light-emitting diodes 5 is guided virtually completely onto the inside 711 of the body portion 71 of the secondary optics 7, no reflector in the linear light 1 is necessary.
    For the rest of the further description, the following definition applies: If reference numerals are included in a figure for the purpose of graphical uniqueness, but are not mentioned in the immediately accompanying description text, reference is made to the explanation thereof in the preceding description of the figures. If reference signs are also mentioned in the description text which belongs directly to a figure, which are not included in the associated figure, reference is made to the preceding and following figures.
    Fig. 2 shows a longitudinal section of the linear lamp 1. The primary optics 6, the secondary optics 7 and the Intermediäroptik 3 are arranged or aligned as intended. It can be seen that each light-emitting diode 5 is assigned exactly one primary lens 61. The primary lenses 61 are each arched in the longitudinal direction and have an approximately circular segment-shaped outer surface.
    The Intermediäroptik 3 is mounted over the entire length of the primary optics 6 adjacent to this and covers them in the direction of secondary optics 7 from. The inner side 312 and the outer side 311 of the Intermediäroptik 3 are configured in longitudinal section as a parallel line.
    The secondary optics 7 surmounted the Intermediäroptik 3 in a longitudinal direction 11 of the linear lamp 1. It covers the entire interior of the linear lamp 1 and the components arranged therein to the outside from. The inner side 712 and the outer side 711 of the secondary optics 7 are designed in longitudinal section as parallel straight lines.
    In Fig. 3, the linear lamp 1 is shown in a cross-sectional view. It can be seen that the board 4, together with the attached LEDs 5, the primary optics 6 and the Intermediäroptik 3 by means of several screws 8 is attached to the base plate 21 of the base profile 2.
    The base 63 of the primary optics 6 is formed in cross-section approximately U-shaped and encloses the LEDs 5 laterally and from below. The outer surfaces of the primary lenses 61 are also formed in cross-section quasi circular segment. The primary lenses 61 of the primary optics 6 thus each have a quasi spherical segment-shaped outer surface.
    The Intermediäroptik 3 encloses with its side walls 32, the primary optics 6 and the light-emitting diodes 5 side. The inner side 312 of its body portion 31 is straight in cross section. The body portion 31 thus has a flat inner side 312. Its outer side 311 is arched, wherein it is formed in cross section quasi circular segment.
    The side walls 72 of the secondary optics 7 have a hook-like area. over this they are mounted on the side walls 22 of the base profile 2. The base profile 2 forms with the secondary optics 7 together a body closed in cross-section, in the interior of the board 4 with the light-emitting diodes 5, the primary optics 6 and the Intermediäroptik 7 are arranged. The inside 712 of the body portion 71 of the secondary optics 7 is formed in a circular segment in cross section. Likewise, the outer side 711 of the body portion 71 of the secondary optics 7 is approximately circular-segment-shaped in cross-section, with sinusoidal waves on the outer side 711 being configured along its circumference. The body portion 71 of the secondary optics 7 is thus configured quasi arcuate.
    Fig. 4 shows a light distribution curve 9 of the linear lamp 1. From the illustration it can be seen that the light is radiated only down from the linear lamp 1. In addition, the adjusted arrangement of the primary optics 6, intermediate optics 3 and secondary optics 7 results in a relatively pronounced and flat beam of light.
    FIG. 5 shows a cross section of a second exemplary embodiment of a linear light 16 according to the invention with an intermediate optic 36. The linear light 16 is identical to the linear light 1 shown in the preceding FIGS. Except for the intermediate optics 36. In particular, it comprises an identical base profile 26 having a base plate 216 and side walls 226, an identical board 46 secured to the base plate 216 by light emitting diodes 56, identical primary optics 66 with primary lenses 616, grooves 626 and base 636, and identical secondary optics 76 with a body portion 716 having an inner side 7126 and an outer side 7116 and side walls 726.
    The intermediate optic 36 includes two sidewalls 326 and a longitudinal body portion 316 interconnecting the two sidewalls 326. The side walls 326, at their ends facing away from the body portion 316, each transition into a nose 336, which engage in the grooves 626 of the primary optics 66.
    The body portion 316 of the Intermediäroptik 36 is designed both in the direction of the secondary optics 76 downward and in the direction of the primary optics 66 upwardly convex. In particular, both an inner side 3126 and an outer side 3116 of the body portion 316 describe a circular segment in cross section.
    As can be seen from FIG. 6, the convexly curved inner side 3126 of the body section 316 of the intermediate optics 36 allows a light distribution curve 96 to be adjusted. In particular, a light cone generated by the linear light 16 can thereby be comparatively focused.
    Fig. 7 shows a cross section of a third embodiment of a linear lamp according to the invention 17 with an intermediate optics 37. The linear lamp 17 is identical except for the intermediate optics 37 as shown in FIGS. 1 to 4 linear lamp 1 and in Figs .. 5 and 6 illustrated linear lamp 16 configured. In particular, it comprises an identical base profile 27 with a base plate 217 and side walls 227, an identical via screws 87 attached to the base plate 217 board 47 with light emitting diodes 57, an identical primary optics 67 with primary lenses 617, grooves 627 and a base 637 and an identical secondary optics 77th with a body portion 717 having an inner side 7127 and an outer side 7117 and side walls 727.
    The intermediate optic 37 includes two sidewalls 327 and a longitudinal body portion 317 interconnecting the two sidewalls 327. The side walls 327, at their ends facing away from the body portion 317, each transition into a nose 337, which engage in the grooves 627 of the primary optics 67.
    The body section 317 of the intermediate optic 37 has a planar upper inner side 3137 facing the primary optic 67 and a lower outer side facing the secondary optics 77. The outer side describes a left first convex curvature 3117 and, symmetrically, a parallel right second convex curvature 3127. Between the first convex curvature 3117 and the second convex curvature 3127, a concave intermediate area is formed on the outer surface. The two convex curvatures 3117, 3127 describe in cross section in each case a circle segment.
    As can be seen from FIG. 8, the convex curvatures 3117, 3127 of the outside of the body portion 317 of the intermediate optic 37 enable an adapted light distribution curve 97 to be produced. In particular, a double and parallel cone of light generated by the linear light 17 can thereby be generated.
    9 shows a cross section of a fourth exemplary embodiment of a linear light 18 according to the invention with an intermediate optic 38. The linear light 18 is identical to the linear light 1 shown in FIGS. 1 to 4 except for the intermediate optics 38 and 6 illustrated linear lamp 16 and the linear lamp 16 shown in FIGS. 7 and 8 configured. In particular, it includes an identical base profile 28 having a base plate 218 and side walls 228, an identical board 48 secured to base plate 218 by screws 58, identical primary optics 68 with primary lenses 618, grooves 628 and base 638, and identical secondary optics 78 with a body section 718 having an inner side 7128 and an outer side 7118 and side walls 728.
    The intermediate optic 38 includes two sidewalls 328 and a longitudinal body portion 318 interconnecting the two sidewalls 328. The side walls 328, at their ends facing away from the body portion 318, each transition into a nose 338, which engage in the grooves 628 of the primary optics 68.
    The body portion 318 of the Intermediäroptik 38 has a planar, the primary optics 68 facing upper inner side 3138 and the secondary optics 78 facing lower outside. The outside describes a left convex curvature 3118 and a parallel right serrated area 3128. The convex bulges 3118 describe in cross section a circular segment. The serrated region 3128 includes three prongs of different sizes. Specifically, the crest nearest the convex curvature 3118 is the smallest and the crest farthest from the convex curvature 3118.
    As can be seen from FIG. 10, the convex curvature 3118 and the serrated region 3128 of the outside of the body portion 318 of the intermediate optic 38 make it possible to produce an adapted light distribution curve 98. In particular, this can produce a one-sided light cone generated by the linear light 18.
    In summary, with the exemplary embodiments of linear luminaires 1, 16, 17, 18 according to the invention described above, it can be shown that, by selecting an intermediate optics 3, 36, 37, 38 adapted to the intended use, a suitable adapted LVK can be generated in an efficient manner. Also, in a single linear lamp 1, 16, 17, 18, the LVK can be changed and adjusted via insertion of a suitable intermediate optics 3, 36, 37, 38.
    FIG. 11 shows a cross-sectional view of a fifth exemplary embodiment of a linear luminaire 19 according to the invention. The linear luminaire 19 comprises a base profile 29 which can be mounted on a ceiling and has a base plate 219. Three parallel plates 49 are screwed onto the base plate 219 by means of screws 89. The boards 49 are each equipped with a straight row of light emitting diodes 59.
    Adjacent to the three rows of light-emitting diodes 59, three primary optics 69 are mounted, each with a series of primary lenses 619 arranged on a base 639. The primary lenses 619 are each arranged in a straight row, wherein in each case a primary lens 619 is provided for a light-emitting diode 59. Between the primary lenses 619 and the bases 639, longitudinal grooves 629 are respectively formed on the primary optics 69.
    Below, adjacent to the primary optics 69, an intermediate optic 39 is mounted with three elongate body portions 319 formed on a base plate 329. The body sections 319 each have one of the associated primary optics 69 facing upper, planar inner side 3129 and an opposite, the associated primary optics 69 facing away from the outside 3119. The outer sides 3119 of the body portions 319 are each convexly curved and circular segment-shaped.
    In operation of the linear light 19, the light emitted by the LEDs 59 and the primary optics 69 penetrating light is adjusted by the Intermediäroptik 39. As a result, a LVK of the linear lamp 19 can be set efficiently and relatively easily. By the three parallel rows of light-emitting diodes 59, a relatively flat light can be generated, which is often desirable, for example, for a basic lighting of a room.
