Description

[0001] A component carrier is specified.

[0002] DE 10 2015 103 535 A1 discloses a luminaire with a component carrier according to the preamble of claim 1. DE 20 2014 101 986 U1 and DE 20 2016 100 264 U1 disclose strip lighting systems with elongated carrier arrangements, which form support rail elements open toward the bottom, into which profile parts with flexible arm regions are inserted. Further track lighting systems with fastening systems are disclosed in DE 20 2012 102 902 U1 and EP 2 827 053 A1.

[0003] One of the challenges to be solved is to provide a component carrier that protects the components arranged within it particularly reliably against environmental influences, especially dust and moisture. Another challenge to be solved is to provide a component carrier that is particularly fire-resistant.

[0004] The problem is solved by a component carrier according to claim 1.

[0005] The component carrier is, for example, a carrier for electronic components. In addition to the electronic components, further electronic components or contact structures can be arranged within the component carrier. For example, electronic components, electronic components, and contact structures arranged in the component carrier are completely enclosed on all sides by the component carrier. For example, the component carrier is designed to be attached to a room ceiling.

[0006] The component carrier comprises a support rail, a mounting rail, and a cover rail. The support rail, the mounting rail, and / or the cover rail each have, for example, a profile along a cross-sectional plane, which profile continues unchanged or essentially unchanged along a longitudinal direction extending perpendicular to the cross-sectional plane. According to at least one embodiment, the profile is essentially unchanged along the longitudinal direction if the profile is unchanged over at least 70%, preferably over at least 80%, particularly preferably over at least 90%, of the length along the longitudinal direction in the cross-sectional plane. The support rail, the mounting rail, and / or the cover rail can each have, for example, a U-, V-, or W-shaped profile. In particular, the longitudinal direction can each run along an axis of symmetry of the support rail, the mounting rail, and / or the cover rail.In particular, the longitudinal direction runs along the main extension direction of the support rail, the mounting rail, and / or the cover rail. For example, the support rail, the mounting rail, and the cover rail share a common longitudinal direction.

[0007] For example, the support rail has a first opening into which the mounting rail can be inserted. If the mounting rail is inserted into the first opening of the support rail, the support rail at least partially surrounds the mounting rail in a lateral plane. The lateral plane runs perpendicular to the cross-sectional plane along the longitudinal direction of the mounting rail. In particular, the component carrier is designed to be fastened to a designated location in the assembled state such that the lateral plane runs horizontally, i.e., perpendicular to the direction of gravity.

[0008] The support rail can, for example, have a greater length along the longitudinal direction than the mounting rail. The length of the support rail in the longitudinal direction can be a multiple of the length of the mounting rail in the longitudinal direction. In particular, several mounting rails can be arranged next to one another in the first opening along the longitudinal direction without the mounting rails protruding beyond the support rail. The length of the support rail in the longitudinal direction preferably corresponds substantially to the sum of the lengths of the mounting rails in the longitudinal direction that are arranged in the support rail.

[0009] Furthermore, the mounting rail can have a second opening. For example, the cover rail can be mechanically coupled to the mounting rail in the region of the second opening. In particular, the cover rail can be inserted into the second opening. If the cover rail is inserted into the second opening, the mounting rail at least partially surrounds the cover rail in the lateral plane. The cover rail has, for example, a length along the longitudinal direction that essentially corresponds to the length of the mounting rail along the longitudinal direction. In particular, a maximum of one cover rail can be inserted into a second opening of a mounting rail without the cover rail protruding beyond the mounting rail in the longitudinal direction. For example, the component carrier comprises just as many cover rails as mounting rails. In particular, the mounting carrier can comprise more cover rails and / or mounting rails than support rails.

[0010] The mounting rail comprises two side walls. The side walls form opposing outer surfaces of the mounting rail. In particular, the side walls extend longitudinally over the entire length of the mounting rail. The mounting rail is, for example, formed in one piece. In this context, "one piece" means that the mounting rail is formed from a single, continuous piece of material. For example, the mounting rail is formed from a sheet metal. The side walls of the mounting rail each have a thickness greater than zero. For example, the thickness of the side walls perpendicular to the longitudinal direction is between 0.5 millimeters and 3 millimeters inclusive.

[0011] The support rail comprises two inner walls. For example, the inner walls extend along the longitudinal direction over the entire length of the support rail. The inner walls are arranged in the region of the first opening of the support rail and at least partially delimit the first opening of the support rail in the lateral plane. In particular, the inner walls have a thickness greater than zero. The support rail can be formed in one piece. In this context, "one piece" means that the support rail is formed from a single, continuous piece of material. In particular, the support rail can be formed from a sheet metal. For example, the thickness of the inner walls perpendicular to the longitudinal direction is between 0.5 millimeters and 3 millimeters inclusive.

[0012] The inner walls are connected to the side walls by force-locking. The inner walls form inner surfaces that face each other. When the mounting rail is inserted into the first opening, the inner walls are in direct contact with the outer surfaces of the side walls of the mounting rail via the inner surfaces.

[0013] In particular, a normal force acts between a side wall and an inner wall in contact with the side wall. For example, the normal force acts along the longitudinal direction over the entire length of the mounting rail and / or the support rail.

[0014] According to at least one embodiment, the cover rail comprises two fastening elements, wherein the cover rail is mechanically coupled to the mounting rail by means of the fastening elements. In particular, the cover rail and the mounting rail are positively connected to one another by means of the fastening elements. For example, the fastening elements are projections, hooks or barbs that engage in the mounting rail in the region of the second opening. The fastening elements engage in the mounting rail, for example, over the entire length of the component carrier. For example, the cover rail is fixed to the mounting rail by means of the fastening elements. In particular, the fastening elements can be formed integrally with the cover rail. In this context, integral means that the cover rail is formed from a single, continuous piece of material.

[0015] According to at least one embodiment, the component carrier comprises a support rail, a mounting rail, and a cover rail, wherein the mounting rail comprises two side walls, the support rail comprises two inner walls, and the inner walls are non-positively connected to the side walls. The cover rail comprises two fastening elements, wherein the cover rail is mechanically coupled to the mounting rail by means of the fastening elements.

[0016] The component carrier described here is based on the following considerations, among others. Component carriers constructed with multiple elements, such as rail-shaped elements, are generally sealed with a sealing material to prevent moisture and / or dust from penetrating the component carrier. A plastic foam, for example, is used as a sealing material, which can generally be highly flammable and only ensures the sealing of the component carrier for a limited period of time.

[0017] The component carrier described here utilizes, among other things, the concept of force-fitting the support rail and the mounting rail, so that the normal force acting between the surfaces of the mounting rail and the support rail prevents the penetration of dust and / or moisture. Advantageously, no sealing material is required to seal the area between the support rail and the mounting rail. This advantageously enables a component carrier that has a particularly reliable seal and requires very small amounts of sealing material, or no sealing material at all, making the component carrier particularly fire-resistant.

[0018] According to the invention, the distance between the inner walls and the distance between the side walls decrease in a common direction, wherein the inner walls are in direct contact with the side walls. In this case, an inner wall runs parallel to a side wall adjacent to the inner wall, so that the inner wall and the side wall are in surface contact with one another. In particular, the side walls and the inner walls run in a wedge shape, so that the surface contact between the side walls and the inner walls forms a mechanical stop when the mounting rail is inserted into the support rail. In particular, the position of the support rail relative to the mounting rail is predetermined perpendicular to the lateral plane by the mechanical contact of the inner walls with the side walls.

[0019] Additionally, grooves can be formed on the support rail, for example, which form a mechanical stop for the mounting rail. The grooves can be formed, for example, on the inner walls and can extend longitudinally over the entire length of the support rail. For example, the grooves engage behind projections or lugs arranged on the mounting rail. In particular, the projections or lugs can be formed integrally with the mounting rail and extend longitudinally over the entire length of the mounting rail.

[0020] Furthermore, a step can be formed in the mounting rail. In the area of ​​the step, the distance between the side walls is greater than the distance between the inner walls. This means, for example, that the mounting rail cannot be inserted further into the support rail than the step, so that the step acts as a mechanical stop perpendicular to the lateral plane.

[0021] According to at least one embodiment, the mounting rail has a mounting area arranged between the side walls. A locking element is arranged on a side of the mounting area facing the support rail, and the locking element can be used to lock the mounting rail relative to the support rail. For example, the mounting area extends along the longitudinal direction over the entire length of the mounting rail. The side walls can be mechanically connected to one another, for example, by means of the mounting area. In particular, the mounting area and the side walls are formed as a single piece.

[0022] The closure element is designed, for example, to fasten the mounting rail to the support rail. For example, the closure element is at least partially inserted into the first opening of the support rail. In particular, the mounting rail is fixed in a predetermined position on the support rail by means of the closure element. For example, the relative position of the mounting rail and the support rail to one another along the longitudinal direction is determined by means of the closure element. In particular, the closure element prevents the mounting rail from falling out of the support rail. The closure element engages behind the support rail, for example in the area of ​​the groove, on a side facing away from the mounting rail.

[0023] In particular, by locking the mounting rail relative to the support rail, a predetermined normal force is maintained between the outer surfaces of the side walls and the inner surfaces of the inner walls. For example, the locking element provides a detachable connection between the mounting rail and the support rail, so that the mounting rail can be non-destructively detached from the support rail by opening the locking element. Non-destructive detachment means that two elements that are mechanically coupled to one another are mechanically decoupled from one another without damaging or destroying one of the two elements or a connecting element, such as the locking element. In particular, the component carrier can comprise a plurality of locking elements by means of which the mounting rail is mechanically connected to the support rail.For example, the majority of closure elements are arranged at regular intervals along the longitudinal direction in the assembly area.

[0024] According to at least one embodiment, the closure element comprises a holding plate and a closing plate, wherein the holding plate is configured to mechanically couple the mounting rail to the support rail and the closing plate is configured to fix the mounting rail in a predetermined position relative to the support rail. The holding plate can be designed, for example, as a spring, in particular as a clamping spring, which engages behind the support rail in the region of the grooves on a side facing away from the mounting rail. In particular, the mounting rail can be mechanically coupled to the support rail by means of the holding plate, wherein the mounting rail and the support rail are movable relative to one another in at least one spatial direction. For example, the mounting rail can be displaced along the longitudinal direction relative to the support rail if the mounting rail and the support rail are mechanically coupled exclusively by means of the holding plate.

[0025] The closure plate is designed to determine the position of the mounting rail along the longitudinal direction relative to the support rail. For example, the closure plate is rotated so that it engages behind the support rail on a side facing away from the mounting rail in the area of ​​the groove. If the closure plate engages behind the support rail in the area of ​​the groove, a normal force acts between the side walls and the inner walls, preventing the mounting rail from moving relative to the support rail along the longitudinal direction. In particular, the mounting rail and the support rail cannot be moved relative to one another when locked. This creates a force-locking connection between the mounting rail and the support rail. In particular, the closure element can be operated from an area outside the component carrier, so that the mechanical connection can be released as required using the closure plate.Advantageously, the locking element enables the mechanical connection between the mounting rail and the support rail to be released without causing any damage.

[0026] According to at least one embodiment, a cavity is arranged in a region in which the cover rail and the mounting rail adjoin one another and / or in the region in which the support rail and the mounting rail adjoin one another, said cavity preventing the penetration of dust and / or moisture into the component carrier. The cavity can be formed in the mounting rail in the form of a first and / or second cavity, each of which extends in the longitudinal direction over the entire length of the mounting rail. In particular, the cavity is formed in the mounting rail. The cavity can, for example, be freely accessible from the outside or be at least partially covered by the support rail and / or cover rail adjoining the mounting rail.In particular, moisture and / or dust can accumulate in the cavity, so that the risk of moisture and / or dust penetrating into a first and / or second cavity of the component carrier is advantageously reduced.

[0027] According to at least one embodiment, a further step is formed in each of the side walls, wherein the first cavity is formed in the region of the further step between the side walls and the inner walls. In particular, the inner surface of the inner wall and the outer surface of the side wall are not in direct contact with one another in the region of the further step. The first cavity between the inner wall and the side wall extends, for example, in the longitudinal direction over the entire length of the component carrier. In particular, the first cavity is completely surrounded by the side wall and the inner wall in the cross-sectional plane. Advantageously, the first cavity prevents moisture from penetrating the component carrier due to a capillary effect between the inner walls and side walls in contact with one another.Advantageously, in the area of ​​the first cavity, the distance between the inner walls and the side walls is too large for moisture to enter the component carrier from the outside due to the capillary effect.

[0028] According to at least one embodiment, the mounting rail has projections, wherein the fastening elements engage behind the projections, and the projections each have a second cavity, wherein the second cavities are open on a side facing away from the support rail. For example, the projections are formed on the side walls of the mounting rail in the region of the second opening. In particular, the projections are formed on mutually facing sides of the side walls. In particular, the projections delimit the second opening in the lateral plane.

[0029] The projections extend in the longitudinal direction, for example, over the entire length of the mounting rail. The second cavity is formed in the projections and can extend along the longitudinal direction over the entire length of the projections. The second cavity can be freely accessible on a side facing away from the support rail. In particular, the second cavity is designed such that the second cavity is open downwards when the component carrier is mounted. Dust and moisture that come into contact with the component carrier in the area of ​​the fastening elements advantageously collect in the area of ​​the second cavity, instead of penetrating between the fastening elements and the projections into the interior of the component carrier.

[0030] Furthermore, the fastening elements can be in direct contact with the projections. In particular, the projections each have an inner surface that runs parallel to an outer surface of the fastening elements. Thus, the inner surfaces of the projections can be in full contact with the outer surfaces of the fastening elements. For example, a normal force acts between the inner surfaces of the projections and the outer surfaces of the fastening elements. In particular, the force-fitting connection between the inner surfaces of the projections and the outer surfaces of the fastening elements makes it difficult for moisture and / or dust to penetrate into the first cavity.

[0031] According to at least one embodiment, the cover rail partially covers the second cavity. In particular, an outer surface of the cover rail runs along the projection and partially covers the second cavity. In particular, the second cavity is partially exposed when the cover rail is mounted on the mounting rail, so that dust and liquid accumulating in the second cavity can drain away. In particular, the outer surface of the cover rail, which partially covers the second cavity, does not run horizontally when the component carrier is mounted. Advantageously, the cover rail thus assists the drainage of liquid accumulating in the second cavity due to gravity.

[0032] According to at least one embodiment, an optoelectronic component can be arranged on a side of the mounting area facing away from the support rail, and the cover rail is designed to be transparent to electromagnetic radiation. For example, the optoelectronic component is configured to detect or emit electromagnetic radiation during normal operation. In particular, the optoelectronic component can be configured to emit electromagnetic radiation in the visible wavelength range, between infrared and UV radiation. For example, the optoelectronic component is an LED light source.

[0033] For example, at least a portion of the radiation emitted and / or detected by the optoelectronic component passes through the cover rail. The cover rail can, for example, be formed from a material that is transparent to electromagnetic radiation. In particular, the cover rail is formed from a plastic such as PMMA or glass. The mounting rail and / or the support rail can each be designed to be opaque to the electromagnetic radiation emitted and / or detected by the optoelectronic component. In particular, the support rail and / or the mounting rail can be designed to be reflective to electromagnetic radiation.

[0034] For example, the support rail and / or the mounting rail can be formed with a metallic material.

[0035] According to at least one embodiment, the cover rail is designed as a diffractive and / or refractive optical element. For example, the cover rail can comprise optical lenses or diffraction gratings configured to influence electromagnetic radiation detected and / or emitted by the optoelectronic component. For example, the cover rail comprises a plurality of lenses configured to influence the radiation profile of the optoelectronic component arranged in the component carrier. Furthermore, the cover element can comprise, for example, filters and / or conversion materials by means of which the color locus of electromagnetic radiation passing through the cover element can be changed. Advantageously, the cover rail can serve both to protect optoelectronic components arranged in the component carrier and to adapt the radiation characteristics of the optoelectronic components.

[0036] According to at least one embodiment, the inner walls and the side walls each have a contact surface at which an inner wall and a side wall are in direct mechanical contact with one another, wherein the contact surface extends over at least 95%, in particular the entire length of the component carrier and the contact surface has a width of at least 10 mm. For example, an inner wall on an inner surface is in direct mechanical contact with a side wall on an outer surface. Perpendicular to the longitudinal direction, the planar contact between the inner wall and the side wall each has a width of at least 10 mm, in particular at least 17 mm. In particular, the planar contact between the inner walls and the side walls extends in this width over at least 95%, in particular over the entire length of the mounting rail and / or the support rail.In particular, the side walls and the inner walls run at least partially parallel to each other. Advantageously, the flat contact between the support rail and the mounting rail enables a particularly tight connection between the mounting rail and the support rail.

[0037] According to at least one embodiment, the contact surface is free of a sealing material. For example, the material of the support rail and the material of the mounting rail are arranged exclusively in the region of the contact surface. In particular, the connection between the support rail and the mounting rail is sealed exclusively via the force-locking connection between the support rail and the mounting rail. Advantageously, a moisture- and dust-tight connection between the support rail and the mounting rail without sealing material enables a particularly reliable seal that is not influenced by the material properties of the sealing material. Furthermore, a seal that is free of a sealing material enables a particularly fire-safe component carrier.

[0038] In particular, the entire component carrier comprises a maximum of 1 wt.%, in particular a maximum of 0.1 wt.%, of a sealing material. For example, a sealing material is arranged exclusively at the ends of the component carrier, which delimit the component carrier on both sides in the longitudinal direction.

[0039] According to at least one embodiment, the support rail and the mounting rail delimit a second cavity, and the mounting rail and the cover rail delimit a first cavity, wherein the first and the second cavity are essentially hermetically sealed against the environment. For example, the mounting rail has openings, in particular in the mounting area, which connect the first cavity and the second cavity to one another. For example, the mechanical connection between the cover rail and the mounting rail is designed such that penetration of moisture and / or dust into the first cavity is prevented. Furthermore, the connection between the mounting rail and the support rail can be configured such that penetration of moisture and / or dust into the second cavity is prevented.

[0040] In particular, the component carrier offers a component arranged in the first and / or second cavity a protection class of IP protection class 64. Accordingly, an electronic component in the component carrier is completely protected against contact, against the ingress of dust, and against the ingress of splash water. Protection against contact in this context means that an access probe with a diameter of 1 mm cannot penetrate the interior of the component carrier. In particular, the access probe can be inserted into any externally accessible opening of the component carrier with a force of up to 100 N without the access probe coming into electrical contact with components arranged inside the component carrier or other current-carrying elements. Protection against the ingress of dust in this context means that talcum powder does not penetrate the first and / or second cavity of the component carrier at ambient pressure.To test for dust tightness, the component carrier is placed in a dust chamber, for example, in which talcum powder is suspended by a dust circulation pump or similar device. Protection against dust ingress is achieved if no dust deposits are visible within the component carrier after a period of 3 hours. To test for protection against splash water ingress, water is sprayed onto the outer surfaces of the component carrier from all directions for two 15-minute periods. Any water that penetrates must not be present in such quantities that the proper functioning of a component arranged in the component carrier or safety is compromised.Any water that may penetrate must not accumulate on insulating parts, where it could lead to leakage currents, reach live parts or windings that are not designed for wet operation, or accumulate near a cable end or potentially penetrate the cables. This advantageously enables particularly reliable protection of components located within the component carrier.

[0041] According to at least one embodiment, the first cavity is delimited in the longitudinal direction by first end caps. For example, the cover rail and the mounting rail form a common first end face that runs transversely to the longitudinal direction. For example, a first end cap is arranged on each of the first end faces and completely covers the first end face. In particular, the first end cap comprises a sealing material that is in direct contact with the mounting rail and / or the cover rail at the first end face. The first end caps on the first end faces thus prevent moisture and / or dust from penetrating the first cavity.

[0042] In particular, a plurality of mounting rails can be arranged next to one another along the longitudinal direction. In particular, two first end caps can be arranged between the first end faces of mounting rails and cover rails arranged next to one another in the longitudinal direction.

[0043] According to at least one embodiment of the component carrier, the second cavity is delimited in the longitudinal direction by second end caps. For example, the second end caps are each continuous transversely to the longitudinal direction, so that the second cavity is completely delimited in the longitudinal direction by the second end caps. The component carrier comprises, for example, exactly two second end caps that delimit the second cavity in the longitudinal direction. In particular, the second cavity can be continuous over the entire length of the support rail.

[0044] For example, the support rail and the first end cap form second end surfaces at the ends of the support rail, which extend transversely to the longitudinal direction. The second end caps each comprise a sealing material that is in contact with the second end surface. For example, a first end cap and a second end cap are arranged at the ends of the support rail, partially overlapping each other. The second end caps prevent, for example, the penetration of moisture and / or dust into the second cavity.

[0045] Further advantages and advantageous configurations and further developments of the component carrier emerge from the following embodiments shown in conjunction with the figures.

[0046] It shows: Figure 1 a schematic sectional view of a component carrier described here, Figure 2a schematic sectional view of a portion of a component carrier described here, and Figure 3 a schematic sectional view of a component carrier described here.

[0047] Identical, similar, or functionally identical elements are provided with the same reference numerals in the figures. The figures and the relative sizes of the elements depicted in the figures are not to be considered to scale. Rather, individual elements may be exaggerated for clarity and / or clarity.

[0048] The Figure 1shows a schematic sectional view of a component carrier 9 described here according to an exemplary embodiment. The component carrier 9 comprises a support rail 1, a mounting rail 2 and a cover rail 3. The mounting rail 2 comprises two side walls 21 and the support rail 1 comprises two inner walls 11, wherein the inner walls 11 are force-fittingly connected to the side walls 21. The cover rail 3 comprises two fastening elements 33, wherein the cover rail 3 is connected to the mounting rail 2 by means of the fastening elements 33. The support rail 1, the mounting rail 2 and the cover rail 3 each have a profile along the cross-sectional plane Q, which profile continues essentially unchanged along a longitudinal direction L extending perpendicular to the cross-sectional plane Q. The support rail 1, the mounting rail 2 and the cover rail 3 each run perpendicular to the cross-sectional plane Q in the longitudinal direction L and parallel to one another.In particular, the main extension plane of the support rail 1, the mounting rail 2 and the cover rail 3 runs along the longitudinal direction L.

[0049] The fastening elements 33 are in direct contact with the projections 23. In particular, the projections 23 each have an inner surface 23a that runs parallel to an outer surface 33a of the fastening element 33. Thus, the inner surfaces 23a of the projections 23 can be in full contact with the outer surfaces 33a of the fastening elements 33. For example, a normal force F acts between the inner surfaces 23a of the projections 23 and the outer surfaces 33a of the fastening elements 33. In particular, the force-fitting connection of the inner surfaces 23a to the outer surfaces 33a makes it difficult for moisture and / or dust to penetrate into the first cavity 91.

[0050] The support rail 1 has a first opening 100 into which the mounting rail 2 is inserted. The first opening 100 is at least partially delimited along a lateral plane E by the inner walls 11. The lateral plane E extends perpendicular to the cross-sectional plane Q along the longitudinal direction L. The mounting rail 2 also has a second opening 200. In the region of the second opening 200, a projection 23 is formed which runs along the longitudinal direction L over the entire length of the mounting rail 2. The second opening 200 is delimited along the lateral plane E by the projections. The cover rail 3 is at least partially arranged within the second opening 200 and is mechanically coupled to the mounting rail 2 at the projections 23.

[0051] The support rail 1, the mounting rail 2, and the cover rail 3 are each formed in one piece. In particular, the support rail 1 and the mounting rail 2 are each formed from a sheet metal. The sheet metal has a thickness of at least one millimeter, for example. The support rail 1 and the mounting rail 2 can be manufactured, for example, using a rolling process. The cover rail 3 is transparent, for example, and can be formed from glass or a plastic, in particular a polymer.

[0052] The distance between the inner walls 11 and the distance between the side walls 21 decreases in a common direction. In particular, the distance between the inner walls 11 and the distance between the side walls 21 decreases along a direction perpendicular to the lateral plane E. The inner walls 11 are at least partially in direct contact with the side walls 21. In particular, the inner walls 11 and the side walls 21 are designed such that the planar contact between the inner walls 11 and the side walls 21 forms a mechanical stop.

[0053] The support rail 1 has two grooves 112 which engage behind two lugs 212 of the mounting rail 2 and thus form a mechanical stop for the mounting rail 2 relative to the support rail 1. The grooves 112 and the lugs 212 each extend along the longitudinal direction L of the component carrier 9 over the entire length of the mounting rail 2 and / or the support rail 1. In addition, the mounting rail 2 has steps 213 on the side walls 21. In the area of ​​the steps 213, the distance between the side walls 21 increases, so that the distance between the side walls 21 is greater than the distance between the inner walls 11. The steps 213 thus form an additional mechanical stop, which determines the position of the mounting rail 2 relative to the support rail 1.

[0054] Between the side walls 21, the mounting rail 2 has a mounting area 22. The mounting area 22 connects the side walls 21 of the mounting rail 2 to one another. In particular, the side walls 21 and the mounting area 22 are formed in one piece. A closure element 4 is arranged on a side of the mounting area 22 facing the support rail 1, wherein the mounting rail 2 can be locked relative to the support rail 1 by means of the closure element 4. In particular, the closure element 4 is designed to engage behind the grooves 112 on a side facing away from the mounting rail 2, so that a normal force F acts between the side walls 21 and the inner walls 11. In particular, the normal force F is so great that the mounting rail 2 cannot be displaced relative to the support rail 1 along the longitudinal direction L.

[0055] The closure element 4 comprises a holding plate 41 and a closure plate 42, wherein the holding plate 41 is configured to mechanically couple the mounting rail 2 to the support rail 1. In particular, the holding plate 41 comprises two clamping springs 410, by means of which the mounting rail 2 can be mechanically coupled to the support rail 1. The clamping springs 410 engage behind the grooves 112 on a side facing away from the mounting rail 2. If the mounting rail 2 is coupled to the support rail 1 exclusively via the holding plate 41, the mounting rail can be displaced along the longitudinal direction L relative to the support rail 1. The mounting rail 2 can be locked relative to the support rail 1 by means of the closure plate 42. For this purpose, the closure plate 42 can be displaced relative to the mounting rail 2 such that it engages behind the grooves 112.

[0056] In the Figure 1In the illustration shown, the locking plate 42 is shown in a non-locking position. For locking, the locking plate is rotated about an axis running perpendicular to the lateral plane E so that the locking plate 42 engages behind the grooves 112. In particular, the side walls 21 must be in direct contact with the inner walls 11 so that the locking plate 42 can engage behind the grooves 112. If the locking plate is in a locking position, a normal force F acts between the side walls 21 and the inner walls 11, which causes such great friction between the support rail 1 and the mounting rail 2 that displacement of the mounting rail 2 relative to the support rail along the longitudinal direction L is impeded. The mounting rail 2 and the support rail 1 are thus non-positively connected to one another.

[0057] An optoelectronic component 6 is arranged on a side of the mounting area 22 facing away from the support rail 1. The cover rail 3 is transparent to electromagnetic radiation, so that electromagnetic radiation emitted and / or detected by the optoelectronic component 6 can pass through the cover rail 3. In particular, the cover rail can be designed as a diffractive and / or refractive optical element. For example, the cover rail 3 can comprise a plurality of optical lenses that extend, for example, along the longitudinal direction L over the entire length of the cover rail 3.

[0058] The support rail 1 and the mounting rail 2 define a second cavity 92, and the mounting rail 2 and the cover rail 3 define a first cavity 91. The first 91 and the second 92 cavities are essentially hermetically sealed from the environment. In particular, the mechanical connection between the support rail 1 and the mounting rail 2 and the mechanical connection between the mounting rail 2 and the cover rail 3 are designed in such a way that the penetration of moisture and / or dust into the first 91 and / or second 92 cavities is prevented.

[0059] For the mechanical connection of the cover rail 3 and the mounting rail 2, the mounting rail 2 has projections 23. The fastening elements 33 engage behind the projections 23. The fastening elements 33 are designed as barbs in this case. By means of the fastening elements 33 and the projections 23, the mounting rail 2 and the cover rail 3 are mechanically connected to one another in a form-fitting manner.

[0060] The projections 23 each have a second cavity 220, wherein the second cavities 220 are exposed on a side facing away from the support rail 1. The cover rail 3 partially covers the second cavities 220. Dust and moisture can accumulate in the second cavities 220, making it difficult for dust and moisture to penetrate into an area between the cover rail 3 and the mounting rail 2 in the region of the projections 23. Preferably, the second cavities 220 are oriented such that they are open downward when the component carrier 9 is mounted. Thus, dust and liquid can escape from the second cavity 220 due to gravity.

[0061] The inner walls 11 and the side walls 21 each have contact surfaces 11a, at which an inner wall 11 and a side wall 21 are in direct mechanical contact with each other. The contact surfaces 11a extend over the entire length of the component carrier 9 along the longitudinal direction L. In the cross-sectional plane Q, the contact surfaces 11a have a width B of at least 10 mm. In particular, the contact surfaces 11a have a width B of at least 17 mm. The contact surfaces 11a are free of any sealing material. In particular, in the area of ​​the contact surfaces 11a, only the material of the mounting rail 2 and the support rail 1 are in direct mechanical contact with each other.

[0062] The first cavity 91 can be delimited in the longitudinal direction L by first end caps 71 (not shown here). The cover rail 3 and the mounting rail 2 form a common first end face 2a, which runs along the transverse plane Q. On the first end face 2a, for example, a first end cap 71 is arranged, which completely covers the first end face 2a. The first end cap 71 comprises a sealing material, which at the first end face 2a is in direct contact with the mounting rail 2 and / or with the cover rail 3. The first end caps 71 on the first end faces 2a thus prevent the penetration of moisture and / or dust into the first cavity 91.

[0063] Several mounting rails 2 can be arranged next to one another along the longitudinal direction L. Two first end caps 71 are then arranged between the first end faces 2a of mounting rails 2 and cover rails 3 arranged next to one another in the longitudinal direction L.

[0064] Furthermore, the second cavity 72 can be delimited in the longitudinal direction L by second end caps 72 (not shown here). The second end caps 72 are each continuous along the transverse plane Q, so that the second cavity 92 is completely delimited in the longitudinal direction L by the second end caps 72. The component carrier 9 comprises, for example, exactly two second end caps 72, which delimit the second cavity 92 in the longitudinal direction L. In particular, the second cavity 92 can be continuous over the entire length L of the support rail 1.

[0065] For example, the support rail 1 and the first end cap 71 form second end faces 1a at the ends of the support rail, which extend transversely to the longitudinal direction L. The second end caps 72 each comprise a sealing material that is in contact with the second end face 1a. A first end cap 71 and a second end cap 72 are arranged at the ends of the support rail 1, partially overlapping. The second end caps 72 prevent moisture and / or dust from penetrating the second cavity 92.

[0066] The Figure 2shows a schematic sectional view of a section of a component carrier 9 described here according to an exemplary embodiment. The side wall 21 has a further step 211, wherein a first cavity 210 is formed in the region of the further step 211 between the side wall 21 and the inner wall 11. In the cross-sectional plane Q, the first cavity 210 is completely delimited by the side wall 21 and the inner wall 11. In particular, the first cavity 210 extends in the longitudinal direction L over the entire length of the component carrier 9. Advantageously, the first cavity 210 prevents the penetration of moisture into the component carrier 9 due to the capillary effect between the inner wall 11 and the side wall 21.

[0067] The Figure 3shows a schematic sectional view of a component carrier 9 described here according to an exemplary embodiment. In this representation of the component carrier 9, a lever 8 is shown, by means of which the closure plate 42 can be displaced from an area outside the component carrier 9. By operating the lever 8, the closure plate 42 can be brought into a locked position or into a non-locked position. In the Figure 3In the illustrated embodiment, the locking plate 42 is shown in an unlocked position. For locking, the lever 8 is rotated about a first axis of rotation 81, so that a part of the lever 8 engaging in the locking plate 42 rotates the locking plate 42 about a second axis of rotation 43, whereby the locking plate engages behind the nose 212. If the locking plate 42 engages behind the nose 212, the position of the mounting rail 2 relative to the support rail 1 is locked. The side wall 21 of the mounting rail 2 comprises a recess in which the lever 8 runs. The lever 8 penetrates the side wall 21 completely, so that the lever 8 penetrates through the recess from outside the component carrier 9 into the first cavity 91. In addition, the mounting rail comprises a further recess in the mounting area 22. The lever 8 penetrates the further recess 22, so that the lever 8 runs both in the first cavity 91 and in the second cavity 92.In the region of the first recess, the lever 8 is in direct contact with the mounting rail 2. In the region of the recess, the lever 8 comprises a sealing material. In particular, the lever 8 is in direct contact with the mounting rail 2 exclusively via the sealing material. The sealing material is, for example, a plastic, in particular rubber, which is designed, for example, in the form of an O-ring. The recess in the mounting rail 2 can, for example, be completely filled with the lever 8, such that the lever 8 prevents moisture and / or dust from penetrating the first cavity 91 through the recess in the side wall 21.
