Definitions

  • the present invention relates to lights, in particular interior lights, which emit a portion of light for direct lighting of the room down and a proportion of light for indirect lighting of the room upwards.
  • lights are designed for example as floor or pendant lights.
  • a lamp of the type mentioned is, for example, in DE 10 2010 003 751 U1 disclosed.
  • As light source for the indirect component LEDs are used.
  • a plurality of heat sinks are provided in the luminaire housing.
  • the direct portion of the light is generated by conventional fluorescent tubes.
  • DE 20 2010 017 320 U1 discloses a floor lamp with a rotatable lamp head.
  • first bulbs for an indirect lighting up and second bulbs for direct lighting down in the form of LEDs are integrated.
  • cooling ribs are arranged around the bulbs of the indirect lighting.
  • the luminaire housing is made of metal.
  • Object of the present invention is to improve the cooling options constructively for a lamp of the type mentioned with LEDs as bulbs.
  • a lamp in particular floor lamp or pendant lamp, which has two light exit surfaces on opposite sides of a lamp housing to emit light for direct lighting and indirect lighting, with light sources in the form of LEDs for generating direct lighting and indirect lighting in thermal contact with the Luminaire housing are arranged in this, and wherein the luminaire housing as an integral body of a solid thermally conductive material is formed with a specific thermal conductivity of more than 30 W / Km, preferably more than 100 W / Km and which has cooling ribs on portions of its surface, wherein the light exit surfaces on the two opposite sides are arranged offset to one another and not overlapping.
  • the entire housing is used as a large heat sink, to which the LEDs are thermally coupled directly or indirectly.
  • the LEDs are thermally coupled directly or indirectly.
  • the integration of the heat sink with the luminaire housing substantially simplifies the design of the prior art.
  • the lighting structure is simpler, because separate frame and fasteners for attaching the heat sink omitted in a housing.
  • the housing is formed of an aluminum die-cast.
  • Aluminum has a very high specific thermal conductivity with comparably low weight. Therefore, this material is particularly suitable for the formation of the housing with integrated heat sink according to the present invention.
  • the cooling fins are arranged on two opposite sides of the lamp housing. The cooling fins can each be arranged next to one of the light exit surfaces for indirect or direct lighting. By using both sides of the luminaire is a sufficient surface available to accommodate the necessary number of cooling fins for cooling. Furthermore, the surface of the housing without cooling fins also contributes to the cooling.
  • the light exit surfaces for the direct and indirect lighting on the two opposite sides of the housing are offset from one another and not overlapping. On the one hand, this allows a flat luminaire design and, on the other hand, it still allows enough space to accommodate cooling fins next to the light exit surfaces.
  • the LEDs for the direct and / or indirect lighting are each arranged on boards, which are fastened in direct thermal contact with the lamp housing at this.
  • the boards can lie flat against the housing or be integrated in recesses of the housing.

  • the LEDs for the direct and indirect lighting are arranged offset from one another in a vertical section (for example parallel to a lamp post or pendulum suspension) of the luminaire.
  • the heat input is distributed in the housing designed as a heat sink and there is enough space on the opposite side of the LEDs to the housing for the arrangement of the cooling fins available.
  • the LEDs for the direct and / or indirect component are each arranged in a recess of the housing.
  • the light exit surface may be formed by the outer edge of the recess and is preferably provided with a transparent cover to form the lamp dust, moisture or even jet water protected.
  • the LEDs are associated with reflectors individually or in groups.
  • the LEDs may be arranged on a planar board in rows and columns, wherein the LEDs individually or a group of adjacent LEDs each having a reflector segment is associated, which has reflection surfaces arranged in the manner of a funnel around the LEDs or the group of LEDs are.
  • the reflection surfaces can be designed to focus or widen the light radiation emitted by the LEDs.
  • an LED group can be assigned to a larger LED reflector, which provides the entire proportion of indirect or direct lighting.
  • the LEDs can also be arranged on a circuit board, which is arranged vertically to the light exit surface of the indirect light component or direct light component. The light is deflected by a preferably flat reflector with several facets, which extends to the light exit surface of the indirect light component or the direct light component.
  • the lamp is designed as a floor lamp and the housing has a receptacle for a lamppost.
  • a snap-in and / or plug-in connection between the lamp and the lamppost is preferred because this allows the lamp to be easily assembled during installation on site.
  • an opening can also be provided in the luminaire housing in order to lay a through-wiring from the mast into the luminaire housing.
  • the mast reception is approximately at the center of gravity of the housing, i. not more than about 200 mm from the center of gravity. In this way, the luminaire housing can be stably stored even at relatively high weight on a single mast.
  • the LEDs are the direct illumination on a planar board, on which the LEDs are provided in a plurality of rows and columns, wherein the board rests on ribs of the housing.
  • the ribs preferably extend parallel to the rows or columns of the LEDs in order to ensure a uniform thermal coupling of the LEDs to the housing acting as a heat sink.
  • the LEDs in the direct lighting and / or indirect lighting can each be combined together on a board with a, preferably segmented, reflector assembly in a module which is inserted into the luminaire housing.
  • the structure with an integrated module facilitates the installation of the luminaire. Furthermore, it is possible to provide different modules within the same luminaire series for different light distributions of the luminaire.
  • FIG. 1 and 2 is a perspective view of a floor lamp according to an embodiment of the present invention shown.
  • the luminaire has on the underside a light exit surface 2 in order to provide light for the direct illumination of a room, and on the upper side a light exit surface 4 in order to provide for indirect illumination to the ceiling.
  • the housing 6 of the luminaire is designed as an integral luminaire housing, which is seen in a perspective view from the light exit side 2 forth as a single component without electrical equipment and other attachments in FIG. 3 is shown.
  • the housing 6 is formed of a solid die-cast aluminum.
  • the housing 6 integrates two functions of the lamp in one element. On the one hand, it provides a receptive surface and protects various lighting components, in particular the light sources and the reflectors. On the other hand, it simultaneously represents the heat sink of the luminaire. For this purpose, cooling fins 8 and 10 are provided on the luminaire housing 6 on two sides.
  • the luminaire housing can, as in FIG. 1 shown to have a cover 12. However, this is cut out in the area of the cooling fins 8 in order to allow cooling by air convection. Furthermore, there are cutouts in the cover 12 in the region of the light exit surface 2 in order to decouple the light from the housing.
  • FIG. 3 is in the area of the light exit surface of the direct lighting (in the FIG. 1 shown with reference numeral 2) to recognize a flat depression, on the bottom of a plurality of ribs 14 are arranged.

  • the reflector assembly 20 has a plurality of approximately funnel-shaped individual reflectors, which are each associated with one of the LEDs 18.
  • the lighting devices for the indirect light component are provided on the opposite side of the housing 6.
  • the luminaire housing 6 has a recess on the upper side with a horizontal side wall.
  • a disk 24 with a plurality of LEDs (not shown separately in the figures) is arranged.
  • the light of the LEDs on the pane 24 is deflected via a segmented, asymmetrically shaped reflector 26 in the direction of the light exit surface 4.
  • the recess in the housing 6 in the region of the light exit surface 4 without the reflector 26 and the LED disc 24 can be seen.
  • an opening 28 can be seen in the lamp housing, which forms a connection from the upper side of the lamp to a region of a mast receptacle 32. Through this opening 28, a wiring for the electrical contacting of the LED disc 24 can be laid.
  • cooling fins 10 are also provided on the upper side of the housing. These act together with the cooling ribs 8 on the bottom to cool the LEDs on the disc 24 and on the board 16.
  • the housing 6 is integrally formed of an aluminum die-cast, all connected to the housing 6 heat-generating components are thermally connected, so that the heat can be dissipated through the large surface.
  • cooling fins 8 and 10 are responsible for the cooling, but that also contribute to the large surface areas on the upper side of the lamp relative to the light exit surface 2 for cooling.
