Definitions

  • Such linear lamps having a lighting means, an operating device for operating the lighting means and a one-piece carrier profile
  • the carrier profile comprises two longitudinal base plates, each having two longitudinal sides and two end faces, the two base plates of the carrier profile each one of the other base plate facing inner surface and one each the outer surface facing away from the other base plate, one of the outer surfaces of the two base plates of the carrier profile a front of the carrier profile and the other of the outer surfaces of the two base plates of the carrier profile form a back of the carrier profile, the light source on the front of the carrier profile and the operating device the rear side of the carrier profile are mounted, and the carrier profile has two lateral connection areas, which connect each of the two base plates on each one of their longitudinal sides together so that the G Circular plates are spaced apart and that a cavity between the two base plates is arranged, can be used to illuminate rooms, squares, work surfaces, stands and the like.
  • Such lights are commonly called Designated linear lights and can for example be mounted directly on walls, suspended or mounted on ceilings or attached to it.
  • linear lights typically include a straight or curved generally elongated or longitudinal base profile or housing that is attached directly or indirectly to the object or wall or ceiling.
  • linear lights usually have a light bar or a carrier profile along which or which a longitudinal lighting means such as a fluorescent tube or a series of light-emitting diodes or a plurality of lighting means and associated control gear are attached.
  • linear lights 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. Therefore, such linear lights are typically equipped with at least one optical system which scatters the light generated or determines a light distribution curve of the linear light.
  • optics are frequently used which cover the illuminant or bulbs such that the light emitted by the illuminants has preferred emission characteristics. For example, optics determine hue, scatter and / or direction of the emitted light. Also such optics are used to complete the linear lights.
  • the base profile When mounting a linear light, the base profile is usually attached to a target position on the wall, the ceiling or the object, for example screwed. One or more provided with lighting carrier profile is then mounted on the base profile mostly detachable. Then the optics are mounted on the base profile or on the carrier profile.
  • the support profile is usually used in linear lights for carrying the light source, the operating device and possibly other components.
  • the carrier profiles often have a front mounting surface and a rear mounting surface.
  • the light source is then attached to the front and the control gear to the back.
  • the front-side mounting surface with the lighting means facing the space to be illuminated or the surface to be illuminated.
  • the carrier profiles are often made of a thermally conductive material, so that the heat generated abrynger can be diverted away from the light source via the carrier profiles from the linear lights.
  • a thermally conductive design of a carrier profile can cause heat also circulates from one component to another component.
  • heat generated by the operating device can pass from the rear side of the carrier profile onto its front side and thus the lighting means and impair this.
  • carrier profile so that a cavity between the front and back lies.
  • front and the back surfaces are formed on two parallel separate base plates of the carrier profile.
  • the base plates are typically connected to one another via lateral connection regions of the carrier element. Between the two base plates is the cavity, which thermally separates the two base plates from each other.
  • a disadvantage of these carrier profiles provided with a cavity may be that heat is transferred to an undesired extent from one component via the associated base plate, one of the connecting regions and the other base plate to another component. In particular at certain points this can lead to an impairment of the additionally heated component. For example, heat generated by an operating device at the point at which it develops the most heat can thus be transmitted laterally to the illuminant via the carrier profile or its base plates and connecting regions. In particular, when using LED bulbs, the heat balance is particularly taken into account, so that a general or punctual additional heating is usually undesirable.
  • the object of the following invention is to propose a linear luminaire or a carrier profile which, respectively, enables an improved heat balance and, in particular, reduces the transfer of heat of different components to one another.
  • EP 2 827 053 discloses a linear lamp of the prior art.
  • EP 2 674 671 discloses a luminaire in which the light sources and the electrical components are separated from each other by recesses formed on the surface of a luminous means carrier.
  • a linear lamp is equipped with a lighting means, an operating device for operating the lighting means and a one-piece carrier profile.
  • the carrier profile comprises two longitudinal base plates, each having two longitudinal sides and two end faces.
  • the two base plates of the carrier profile each have one of the other base plate facing inner surface and each one of the other base plate remote from the outer surface.
  • One of the outer surfaces of the two base plates of the carrier profile forms a front side of the carrier profile and the other of the outer surfaces of the two base plates of the carrier profile forms a rear side of the carrier profile.
  • the light source is mounted on the front side of the carrier profile and the operating device on the rear side of the carrier profile.
  • the carrier profile has two lateral connection areas, which in each case connect the two base plates to each one of their longitudinal sides so that the base plates are spaced apart from each other and that a cavity between the two base plates is arranged.
  • the carrier profile comprises two incisions which each extend between one of the two connection regions and one of the two base plates connected to it along the associated longitudinal side.
  • the front side of the carrier profile is aligned together with the light source in a direction of illumination.
  • the front side of a ceiling-mounted linear lamp is directed downwards, that is, the front side forms an underside of the carrier profile and the back side forms an upper side thereof.
  • the light source is oriented downward and the operating device between carrier profile and ceiling arranged.
  • the inner and outer surfaces of the longitudinal base plates may in particular be rectangular.
  • the long sides can be several times longer than the front sides.
  • the inner and outer surfaces of the longitudinal base plates can also be designed bent.
  • connection areas each connect the two base plates to one another on each of their longitudinal sides, they are formed laterally on both sides of the base plates. They connect, for example arcuate or angled base plate comprising the front with the base plate comprising the rear side on the longitudinal sides thereof.
  • the connection areas may be continuous or quasi-continuous, so that they laterally delimit the cavity between the base plates.
  • the cavity between the two base plates can be filled in particular with air.
  • it can be provided with openings so that air can flow in and out.
  • Such a cavity allows thermal insulation of the two base plates or the front and the back of each other. In particular, this can be a transition of heat from the operating device to the bulb or vice versa reduced.
  • the carrier profile can be relatively thin at the incisions, so that the heat transfer or heat transfer at this point is relatively poor. This can be effectively prevented in a relatively simple manner that heat is transferred from a component on the one to another component on the other side of the carrier profile, whereby the thermal insulation of the front of the back can be improved. In particular, it can thus be avoided, for example, that heat from the operating device mounted on the rear side is transmitted via the carrier profile to the illuminant mounted on the front side and impairs the latter.
  • the embodiment of the carrier profile according to the invention thus makes it possible in a simple manner to achieve an improved efficient thermal separation of operating device and lighting means or of the front and rear sides of the carrier profile.
  • the carrier profile may have a mounting structure, via which it can be mounted on a housing or base profile.
  • a mounting structure having hooks that can engage in corresponding receptacles or behind corresponding undercuts of the housing.
  • the cuts in the carrier profile may have any suitable shape.
  • they may be formed as notches or channels.
  • they may have a V-shaped cross section, so that they narrow with increasing depth.

  • the cuts preferably each have a maximum width corresponding to at least 50% of a thickness of the base plates, at least 70% of the thickness of the base plates, at least 80% of the thickness of the base plates, at least 90% of the thickness of the base plates or at least the thickness of the base plates. Sections so dimensioned allow for an interruption of the thermal transition between the two base plates to a sufficient extent. As a result, front and rear sides can be thermally decoupled from each other efficiently, so that the components of the linear light mounted on the front and rear sides are protected.
  • the base plates of the carrier profile each comprise two end faces, which are not connected to each other, so that the cavity is open on the front side.
  • a cavity allows air in its interior or other suitable medium can be efficiently replaced. It can efficiently heated air escape from the cavity and be replaced by not yet heated air.
  • the base plates of the carrier profile are arranged parallel to each other.
  • Such an arrangement of the base plates to each other is useful for many applications. For example, it may be preferred for attached to ceilings or walls linear lights. Also, such carrier profiles can be relatively easy to manufacture and obstruct.
  • the longitudinal sides of the base plates of the carrier profile are preferably straight. Such a design of the long sides allows the realization of a straight linear lamp, which is desired in many applications. For example, linear luminaires are often preferred for ceiling lighting of rooms and hallways.
  • the carrier strip is advantageously made of a thermally relatively highly conductive material so that heat produced by the operating device and the lamp can be efficiently dissipated.
  • the carrier profile is made of a metal and in particular of aluminum or coated aluminum.

  • the clamp connection can be strengthened, so that, for example, the optics can be sufficiently firmly held on the carrier profile.
  • such a toothing further complicate the penetration of moisture and thus improve the density of the linear lamp.
  • the inner side walls of the two clamping channels are preferably shorter than the outer side walls of the two clamping channels.
  • Such a configuration of the side walls allows on the one hand a sufficiently strong connection between the carrier profile and, for example, an optic. On the other hand, it allows in particular that a moisture transfer can be prevented labyrinthine. This can allow a particularly efficient seal in a relatively simple manner.
  • the carrier profile has two laterally of the base plates and parallel to the longitudinal sides extending clamping walls.
  • Such clamping walls can serve as male parts of a clamping connection. This can be the top be described implemented in reverse, so the male part on the support member and the female part, for example, on the optics.
