Definitions

  • the invention relates to a downlight which utilizes LEDs as light sources (light emitting diodes, which also include organic light emitting diodes).
  • Downlights are often used as recessed ceiling luminaires (or ceiling mounted luminaires) to illuminate interiors. As built-in or surface-mounted luminaires, these must have a compact design. When using LEDs as bulbs in downlights there is the particular difficulty that the high-power LEDs require a large heat sink, which is not easily integrated into the downlight.
  • a downlight comprising: a support structure for installation or mounting in or on a ceiling with an opening defined by a frame of the support structure for the light exit of the downlight, a heat sink, which is held on the frame structure, at least one LED assembly thermally connected to the heat sink and mechanically attached to the heat sink, and at least one reflector assembly extending from the LED array toward the opening of the support structure, the heat sink being attachable to the support structure in at least two different mounting positions, such that the LED array mounted on the heat sink is at different distances from the opening the carrying structure assumes.
  • the heat sink can be attached to the support structure in at least two different installation positions
  • the LED arrangement can be attached to the heat sink in at least two different installation positions, such that the LED attached to the heat sink -Anowski different distances relative to the opening of the support structure assumes.
  • This construction makes it possible to use different reflector assemblies for the same downlights. For example, relatively long reflectors are necessary for particularly low-beam downlights. These can be mounted on the LED assembly when the heat sink is in the installed position in which it has a relatively large distance from the opening of the support structure. For broader downlights, a shorter reflector assembly is often desirable. This can be provided on the downlight according to the invention, when the heat sink is mounted in the installed position with a smaller distance from the opening of the support structure.
  • the reflector assemblies extend at least over the entire distance between the LED array and the opening of the support structure.
  • a reflector assembly that is shorter than the distance between the LED array and the opening of the support structure would result in a light exit above the lower edge of the downlights and thus light loss due to absorption in the housing or in a light trap on the housing. It is therefore preferred that the reflector assembly extends at least as far as the lower edge of the downlight. According to some embodiments, the edge of the reflector assembly may also project downward beyond the opening of the downlight.
  • the edge of the reflector assembly which defines the light exit opening of the reflector assembly, in the same level as the edge of the opening of the support structure, which is located, for example, in the installed state of the downlight at the level of the underside of the ceiling, in which the downlight is installed.
  • the LED arrangement is attached to a surface of the heat sink facing the opening of the support structure, preferably removable.
  • the surface of the heat sink may extend parallel to the plane defining the opening in the support structure.
  • the surface of the heat sink may have a plurality of positions for mounting the LED array or for attaching a plurality of LED arrays.
  • one or more LED arrays can be mounted in different positions in the downlight within the downlight, whereby different light distributions can be achieved with the same or different reflector assemblies.
  • the same downlights can be equipped with a different number of LED assemblies to produce downlights of different light intensity and light distribution.
  • the plurality of positions for attaching LED arrays each have separate, preferably separately controllable, electrical connection means for the LED arrays.
  • the wiring may be attached to the heatsink or loosely routed.
  • the downlight can be variably equipped with LED arrangements at the installation site without having to change the wiring.
  • the separate controllability of the connection means it is also possible, the same downlight with multiple LED arrangements for different lighting tasks, for example lighter or darker, or for different light distributions, or different light colors use.
  • the reflector assembly has a rotationally symmetrical reflector surface.
  • These reflectors are suitable for generating a circular light field contour of the illumination plane.
  • the reflector surface may also be asymmetrically shaped.
  • a wall which is adjacent to the position of the downlight in the ceiling can be illuminated.
  • the same downlight can be equipped with different reflector assemblies. The different heights of the reflector assemblies can be compensated by the inventive different installation positions of the heat sink in the support structure.
  • the LED assembly is mounted in a plane on the heat sink, which is inclined relative to a plane which defines the opening of the support structure.
  • This arrangement is preferred for asymmetrically radiating downlights. Inclination angles between 10 ° and 80 °, preferably between 20 ° and 60 °, in particular preferably between 30 ° and 60 °, can be provided.
  • the LED array can be attached to the heat sink either directly or via a planar board which is plugged into a surface of the heat sink.
  • the surface of the heat sink to which the LED array is attached may be inclined to the predetermined angle relative to the plane defining the opening of the support structure.
  • the LED arrangement may also be attached to the heat sink via a carrier, for example via an angled circuit board or metal body.
  • the surface of the heat sink which is adapted for mounting the LEDs, parallel to the plane which defines the opening of the support structure may be provided.
  • This embodiment is particularly suitable for use with different LED arrays and reflector assemblies.
  • the same downlight ie with the same heat sink, can be used with a surface-mounted LED array for emitting light vertically downwards or with an asymmetric light output LED array mounted on an angled board.
  • the LED array for a downlight of the present invention may include a plurality of colored LEDs, particularly LEDs having different colors, e.g. Red, green and blue.
  • the colors red, green and blue for example, produce white light.
  • the LED arrangement or a plurality of LED arrangements can also be controlled differently, so that color effects of the downlight can be set by the differently colored LEDs.
  • LEDs with white light can also be used.
  • the cooling body has a plurality of cooling ribs, wherein some cooling ribs are shortened with respect to the other cooling ribs of the cooling body or have recesses in order to adapt the peripheral shape of the cooling body to the support structure.
  • the support structure includes, for example, a plurality of approximately perpendicular to the ceiling support. These limit the space available for the heat sink. In order to provide a heat sink with the largest possible surface, correspondingly long cooling fins are desired. By shortening or cutting out only a few cooling fins, however, the total cooling capacity of the heat sink is not significantly reduced. However, the heat sink can thereby be adapted to the available space in the support structure.
  • the maximum diameter of the heat sink in cross-section parallel to a plane defined by the opening of the support structure is smaller than the maximum diameter of the opening in the support structure in said plane.
  • the heat sink has a copper core and / or a copper base side.
  • the copper core extends in particular in the longitudinal direction of the heat sink vertically to the mounting plane of the downlight. This allows long heatsinks produce with a small diameter. Due to the vertical mounting direction, the mounting and removal of the heat sink and the mounting of the heat sink in different mounting positions is possible because no projections of the heat sink protrude over the support structure in a vertical direction relative to the mounting plane of the downlight.
  • the heat sink is partially surrounded by a jacket which has fastening means for fastening to the support structure.
  • the fastening means such as e.g. Hooks or boards, also be integrated directly on the heat sink.
  • a downlight system which comprises at least one downlight according to one of the previously described embodiments, wherein the downlight system further comprises at least two reflector assemblies that produce a different light distribution, in particular at least two reflector assemblies with different height and / or with rotationally symmetrical and asymmetrical reflector. If the reflector system has at least two reflector assemblies, but both have the same height, according to an independent aspect of the invention, the support structure of the downlight can also provide only a mounting position of the heat sink.

  • the opening 6 is sized so that all components of the downlight, which are fastened within the support structure 2, can be mounted through the opening.
  • the opening may be smaller, in which case the components are mounted in the support structure before the downlight is inserted into the ceiling.
