Definitions

  • the invention relates to an LED luminous reflector, in particular for a luminaire with light emitting diodes sequentially arranged in a longitudinal direction.

  • LED luminaire reflectors are generally known in the art and are used, for example, in LED luminaires, that is to say luminaires in which the luminous means are formed from LEDs, to form the light emission characteristic, in particular frequently the aperture angle of the light cone emitted by LEDs is large and thus beam-forming reflectors can be used when smaller beam or generally other radiation characteristics are desired than those originally given with a light emitting diode.
  • Such LED strips or LED strips are often used as a preconfigured component in luminaires, wherein for shaping the Lichtabstrahl futurizing of each individual light-emitting diode according to prior art every single light-emitting diode receives its own reflector body, for which it is to be arranged around the light emitting diode around, optionally with the rigid or flexible board is to connect.
  • every single light-emitting diode receives its own reflector body, for which it is to be arranged around the light emitting diode around, optionally with the rigid or flexible board is to connect.
  • special reflector fittings can be provided, which are connected to the circuit board surrounding the LED in order to grasp such a reflector.
  • luminaires with such LED strips or LED strips and the previously known individual reflector arrays are expensive and require a large number of equal handling steps in the production, since sometimes several tens or even several hundred light emitting diodes of a single LED strip or LED strip within a Luminaire with such an LED strip or band is to be provided with reflectors.
  • it is also an object of the invention is a luminaire of the type mentioned, for example, from the utility model DE 20 2011 104 303 the same applicant is known to develop by means of an LED luminaire reflector, which solves the above object.
  • an LED luminaire reflector which is channel-shaped in a longitudinal direction, with a recesses having bottom portion and two opposing, upstanding from the bottom area, diverging Side walls whose upper edges in a direction perpendicular to the longitudinal extension are resiliently movable towards each other. Diverging is understood to mean that the distance of the side walls from one another increases from below (bottom area) upwards.
  • Directional information is set in the sense of the invention in relation to an upward accepted light emission.
  • Such an LED luminaire reflector has the advantage that it has, according to its length, which is present in said longitudinal direction, a plurality of recesses corresponding to a given Repetierterrorism, thus according to the invention, a single LED luminaire reflector for a plurality of multiple LEDs simultaneously Can use, which offers particular advantages if in a light, as mentioned above, several light emitting diodes are used, which are also strung in an equidistant distance from one another in a longitudinal direction. Therefore, such an LED luminaire reflector with the mentioned LED strips or LED strips can be used with particular preference.
  • each individual LED of such a lamp with a single separate and separate reflector, but there is the possibility to use a single or only a few inventive channel-shaped LED luminous reflectors in a corresponding light, the same time as a reflector for several, preferably all light-emitting diodes of this light is used.
  • Such an attachment according to the invention is advantageously achieved in that both the interior of the receiving profile in the direction of the opening is formed widening, as is the case with the luminaire reflector by the diverging side walls, which causes such a luminaire reflector according to the invention with against the spring force acting on each other to moving side walls after insertion into a lamp with such a prescribed receiving profile tends to according to the spring force to push apart the upper edges of the diverging side walls, that is to increase the distance between the edges, and thereby exerts a force on the interior of the receiving profile, which, as described, in turn is widening in the direction of the opening.
  • An inventive LED luminaire reflector and a lamp according to the invention of the aforementioned type in connection with such a luminaire reflector thus have in common the particular advantage that it requires no special fastening measures to attach the LED luminaire reflector in the lamp according to the invention.
  • a luminaire reflector according to the invention need only be pressed from above into the interior of the receiving profile, for which first the diverging side walls, in particular their upper edges, contact the abovementioned projections during insertion, through which projections the diverging side walls are moved toward one another and after passing the projections in Insertion direction behind the projections, the distance of the diverging side walls or their upper edges in turn increases and thus engage behind the projections in the insertion direction.
  • a reflector of this type described in connection with a lamp of the type described in the direction of longitudinal extension direction is basically displaced so that alignment of the individual recesses in the reflector relative to the LEDs or other electronic components comparatively easy can be done without the need for the solution of other fasteners. Furthermore, it is advantageous that in principle all recesses within an LED luminaire reflector according to the invention are simultaneously optimally positioned relative to one another and to the corresponding light-emitting diodes or also other electronic components. It is also advantageous that such a reflector can be shortened in length without further notice.
  • the two side walls mentioned above are symmetrical to one another, wherein this symmetry can be understood in particular with respect to a center plane which is oriented parallel to the longitudinal direction and centrally to the recesses, in particular perpendicular to the bottom area, wherein a mirror symmetry can exist to this center plane.
  • Such an embodiment has the advantage that the emitted light cone of a corresponding luminaire with such an LED luminaire reflector substantially corresponds to a band of light whose opening angle is designed to be symmetrical about the light sources in the longitudinal direction, given by the LEDs.
  • an upper region of each side wall is folded outwards. Such a folding can, for example, take place such that the folded upper area lies in a plane parallel to the floor area.
  • a light exit slot which is more or less tapered in relation to the maximum possible width, depending on the width of the folded region, accordingly results.
  • the outwardly folded region of each side wall has a width perpendicular to the direction of longitudinal extension which corresponds to 15 to 40%, preferably 20 to 30% of the height of the folded region above the bottom region.
  • the embodiment may also be such that the sum of the widths of the two folded regions of both side walls corresponds to the width of the bottom region.
  • the side walls of the LED luminaire reflector which extend between the bottom portion and the upper folded portion, are completely non-contact with the inner wall portions of a lamp of the type described above.
  • a contact between Reflector and luminaire or their recording profile thus results in this case only at the outer edges of the reflector.
  • the side walls at least in regions, preferably over the entire length and over the entire height of each side wall above the bottom area have an outer shape which is adapted to the inner shape of a channel-shaped receiving profile of a lamp into which the LED reflector can be used.
  • this additionally stabilizes the position of the LED luminaire reflector in one luminaire, and on the other hand, the reflector can also be thermally better coupled to the receiving profile due to an enlarged contact surface between the LED luminaire reflector and the receiving profile, thus taking on additional cooling tasks in addition to its reflection tasks ,
  • the adaptation between the exterior of the diverging side walls of the LED luminaire reflector and the interior of the aforementioned channel-shaped receiving profile of a lamp can be made such that the contours of both components in a cross section perpendicular longitudinal direction at least partially preferably completely, based on the height of the side walls of the LED Luminaire reflectors above the floor area are the same.
  • both side walls of the LED luminaire reflector according to the invention are asymmetrical to one another.
  • Such an asymmetry can be given, for example, with respect to a center plane parallel to the direction of longitudinal extent and centered to the recesses in the bottom area, in particular to a center plane which is oriented perpendicular to the floor area.
  • Such an asymmetry here has the advantage that, in a corresponding manner, the radiation profile can be configured asymmetrically to a line in which the individual light-emitting diodes are lined up as light sources. For example, this opens up the possibility of positioning luminaires according to the invention symmetrically in a room and, independently of this object symmetry thus created, to generate deviating light fans.
  • asymmetries between the two side walls of the LED luminaire reflector according to the invention can result in various constructive ways and manners which can also be combined with one another.

  • one of the side walls occupy a different angle relative to the bottom portion than the other side wall or at a curvature of the side walls in section perpendicular to the longitudinal direction of a different curvature or have a different radius of curvature. This can mean that the centers of the respective curvature to the center plane mentioned above have different distances.
  • only one of the two side walls is folded outwardly in an upper region around a fold line lying in the longitudinal direction of extension.
  • Such a folding can be carried out as in the previously described embodiment such that the folded region lies in a plane parallel to the plane of the bottom region, or else such that the planes intersect one another.
