  • the invention relates to a luminaire field, in particular for the Interior lighting, with a plurality of at a distance arranged light emitting diodes, a support member on the light emitting diodes are arranged and one in the emission direction arranged in front of the light emitting diode reflector body, the several interconnected individual reflectors for the Having light-emitting diodes.
  • Such a luminous field is for example from DE 201 16 022 known.
  • the luminous field disclosed in this publication For lighting rooms consists of a variety of Light-emitting diodes, which are formed on a support plate as a carrier Support element are arranged, and a reflector body, the in Abstrahlraum arranged in front of the carrier board and the LEDs is to the light emitted by the LEDs to light bundle up.
  • the disclosed in DE 201 16 022 reflector body consists of a one-piece injection molded part with several channel-like Individual reflectors. These individual reflectors are preferably steamed with aluminum to a corresponding degree of reflection to achieve.
  • there are transparent, light-bundling Plastic optics known in conjunction with known luminaire fields are used as a reflector body.
  • Known reflector body are formed as plastic elements, which have a low temperature resistance and also have a high insulation effect. This isolation effect can cause heat build-up in LEDs with higher power and thus lead to defects.
  • WO 99/41 785 light panels are known, the a plurality of grid-like arranged on a support element LEDs consist.
  • the LEDs of these light panels have for a uniform and sufficient interior lighting too low benefits.
  • To a sufficient for lighting purposes To obtain luminous intensity, the individual LEDs would have to be placed so close to the light panels that not every LED is equipped with a single reflector could be.
  • the invention is based on the object, a generic Luminaire field to develop such that this also with Light-emitting diodes with a larger wattage can be used.
  • Raster has the function of the light-emitting diodes flat emitted light on a certain area evenly to distribute and to make a glare limitation. by virtue of the heat resistance and the heat conducting properties of the Metal sheet grid can light emitting diodes with correspondingly high Wattage be used easily.
  • the grid according to the invention is open, ie in Emission direction in front of the LEDs no shielding or Plate is arranged, cools the continuous air convection the LEDs to prevent heat build-up.
  • This embodiment is preferably in light emitting diodes with a particular high performance realized.
  • the thermal conductivity of the Metal sheet grid is also sufficient to the resulting Dissipate heat when at the grid in front of the light emitting diodes Lenses or glass plates are arranged.
  • the metal sheet of the grid is highly reflective and the grid is formed in several pieces.
  • the highly reflective property can be e.g. by using pre-anodized, anodised and achieve correspondingly coated metal sheets.
  • pre-anodized aluminum is used, which is high is reflective and has a reflectivity of 95 percent having.
  • pre-anodized and coated metal sheets have a very hard, almost ceramic surface can these are only mechanically processed without restrictions Reflection properties of the surface damage. So are These materials are only limited thermoformable, without it too Microcracks in the surface and thus the destruction of the lighting properties comes. That's why Grid when using pre-anodized metal sheets constructed in several parts to such damage to the reflective To avoid surface.
  • the Single reflector surfaces consist of several individual plates, the connected by tabs.
  • the inventive multi-part design of the reflector can thus be with any pre-anodized metal sheets each Any geometry of the individual reflector surfaces without damage realize the reflection surfaces.
  • each two opposite Reflector surfaces integrally formed on the grid and the adjacent, also opposite reflector surfaces are attached as separate parts to these tabs.
  • Grid part of a grid closure integrally formed is to simply connect this with a light housing can.
  • This part of the grid fastener can, for example as an integrally formed locking tab with a latching hook include. In an alternative embodiment, this tab have an undercut.
  • the support element of the luminous field as Heat sink formed.
  • the LEDs are thus raster-like arranged on the serving as a heat sink support member and can be arranged together with this in known luminaire housings become.
  • the training according to the invention makes it possible for the first time, luminaire fields with LEDs of high wattage subsequently to arrange in existing luminaire housings, this so retool.
  • the heat sink leads to the individual Light emitting diodes effective heat.
  • the luminous field according to the invention consists essentially from a square inlaid in a suspended ceiling Frame 10, in its opening a square also Metal sheet grid 20 is inserted, and one on the frame 10th attached heat sink 40, at the bottom of several LEDs 50 are arranged like a grid.
  • the frame 10 is in a known manner a bridge-like Mounting bracket 30 is provided for attachment to the ceiling.
  • the grid according to the invention has a total of 16 grid-like arranged Single reflectors 22 on, each having the geometry have a truncated pyramid.
  • the grid 20 consists of a sheet metal profile made of pre-anodised aluminum with square Floor space.
  • the individual reflectors 22 are made of sheet metal profile truncated pyramidal reflector surfaces 24 punched out and bent up out of the plane of the grid 20.
  • the Reflector surfaces 24 have at the oblique outer edges at a distance from each other two fastening tabs 26th on.
  • On this mounting tabs 26 are used to form the complete individual reflectors 22 also truncated pyramidal Part reflectors 28 fitted, the corresponding openings for these fastening tabs 26 have.
  • By bending over the fastening tabs 26 become the separate partial reflectors 28 on the grid 20 to form the individual reflectors 22 fixed.
  • This "multi-piece" structure of the grid 20 allows the use of pre-anodized metal sheets for training arbitrary geometries of the individual reflectors, without the reflective surface damaged during deep drawing or the like becomes.
  • the heat sink 40 is parallel at its top with several extending cooling fins 42 and provided on its underside provided with a planar mounting surface 44.
  • On this mounting surface 44 are corresponding to the individual reflectors 22 of the grid 20 light-emitting diodes 50 with high wattage so at a distance from each other arranged that in the installed position in each case a light-emitting diode 50 projects into an upper opening 29 of the individual reflectors 22.
  • each individual reflector 22 a associated with corresponding LED 50.
  • the regular spaced from each other on the mounting surface 44 are also several LEDs on a connecting them Substrate can be arranged, which then attaches to the mounting surface 44 of the heat sink is attached.
  • L-shaped grid plate 60 integrally formed in each case in the corners of the grid 20 are in the installed position outside partial reflectors 28 L-shaped grid plate 60 integrally formed.
  • These grid tabs consist of a first from upper end of the partial reflector 28 is vertically upwards extending section, which then turns into a 90 degree bend an outwardly projecting horizontal section 62 passes and then after a further 90 degree bend up into one longer, second vertical section 64 merges, the its upper end has a locking projection 66.
  • These resilient grid plate 60 engages in the installed position a corresponding trained grid plate 80 with a locking projection 82, to the grid 20 on the frame 10 and on the heat sink 40 to fix.
  • an inventively designed luminous field can be realize the lighting of a room with 100 - 300 LUX luminosity.
  • other grid divisions can also be used realize as the mentioned 4 X 4 screening.
  • a sheet metal grid with a as Carriers for the LEDs serving heat sink can also existing lights with conventional bulbs on the operation be converted with LEDs. For this purpose must only those from the reflector, the heat sink and the LEDs existing unit are used in a luminaire.
  • the metal sheet grid according to the invention is distinguished in comparison to the plastic barriers by a high heat resistance and good heat dissipation and thus supports the heat dissipation even with extreme temperature development of LEDs with high performance.
  • the partial reflectors of the grid shield on the one hand the diodes off and on the other hand focus the light due to the high reflection effect of the material used.
